How to Make FREE Horsepower!!!
Вставка
- Опубліковано 23 чер 2019
- There aren’t many times where you can put some time into your car, and make horsepower without buying car parts. In this video, I spent a good 7 hours into my upper and lower intake manifolds where made everything smooth. Any time that the air that is rushing into the engine has to slow down for a bend or stop at a shelf, is lost power. There is a company that offers this porting service for $700USD exactly what I am going to be doing today, which is why I wanted to see if I could get the same results without spending a dime. That being said, I do have these tools from when I ported the cylinder head on my big turbo MINI ( • How to Port and Polish... ). All of the safety equipment and tools that were used in this video can be found below.

WHO WANTS TO SEE A DYNO COMPARISON!?!?
That would be a big waste of money on a dyno run. You probably won’t even be able to see the change if any at all. Bruh you are better then this BS video!!
Video should've started with a fun session with the normal factory , then do the sanding and see if there is any difference. Or just say fuck it call summit and have them give you a kit to force feed it 👍 . My opinion alot of time spent shaving and sanding for not alot of gain.
Curious to see if there's any gain. Highly doubtful though!
+0.001 hp
Exactly 😂
Make sure you do a "before" dyno run for proper comparison.
I will be!! I found a local shop who just got a dyno!!
You don't need to. It's proven port matched heads. Smooth runners etc gives you more power!
Love the video buddies! I def rely on your awesome vids for many of my z34 upgrades! Not a fan of all the nay sayers out here love that your actually making vids and helping us save some hard earned dollars! For a day or 2 of work at the most totally worth it in my build! Keep doing your thing man!
First time seeing someone port a plastic intake manifold.
first time owning a car too? go to Z1 they have custom ones they do.
Are you 15?
This is honestly an underrated video - back in the 90's we used to pay good money to have our small block V8s ported and polished, and now you can DIY with a video like this that basically gives you the trade secret. Great info and nicely done!
Thanks Carlos! Feel free to share it and give it a thumbs up 👍
Thank you for this. Helps us z34 guys out a lot. Can't trust these suckers out here. Nice knowing we can come to you for adaquete training and knowledge.
When are we going to see that damn mini get tuned and driven!!
When he figures out what's wrong with it.
I just ported my plastic intake for my 4.6 V8. I posted a quick 40 second video of a port that's done vs the other ports... It's a pretty big difference on mine.
Mustang?
A dyno comparison would be a good idea - the problem is the hp "gain" would be within the variance of error and therefore will not be sensitive enough to pick up any of the small gain or loss seen. Any change seen would be the result of dyno variances between runs. Swallow the loss of 7 hours of your time and go put on the bolt ons with a tune that will make a measurable difference.
True... not to mention the possibility of distorting the plastic manifold with heat.
Great vids man I wanna see your vhr run with others
Nice job Milan 👍
To all the peoples that are saying this is not much gain, that is dumb, because, at the end of the day, it's a gain, not a loss. So definitely it's an improvement, and it's free and easy to do if you move your asses and do the work by yourselves.
Now, you will definitely need to tune the ECU to keep the improvement, as most of the cars tend to correct the ECU settings and will roll it back to the factory tune, once it sees what was done to it, so keep that in mind
What can work even better is to port and polish the cylinder head too, but that is not for everybody and it can cost you a lot if you mess it up. To get the most out of it, port and polish the throttle body, intake manifold, cylinder head (Intake and exhaust ports), and the exhaust manifold or headers. That will make a really nice difference, and can be done for free if you don't want /need any special porting patterns
It is not free. A day's labour is what, $150-200 for average wage earners? Spend an extra day at work then buy a K&N air filter. 5hp instead of 1.
@@thequietkiwi what is not free, to diy? I assume that most of the peoples don't work 24/7, so in your free time you can do whatever you want. Nobody said to runaway from work, just to work on your car.😅
I have been "building" my car in my free time, of course, and guess what, it runs and sounds better. Just a valve delete from my intake and porting of the throttle body, and intake gaskets matching, made it sound like it had a high flow air filter, and now with the k&n sounds even better then other stock cars, with just an k&n air filter.
Great content like always! Good luck with all your projects brotha!
Step 1: remove entire exhaust system.
Step 2: get pulled over.
Step 3: put it all back on.
Idk I haven't been pulled over yet
Just install active exaust cutouts to bypass your catylytic converters and wire it up to a hidden switch.
If they go far enough to request an inspection you just have to say running them open is intended for use on track only.
Will only cost a $200-$400 depending on how many cats you have, the bore and where you install the bypasses.
If you think that would help 🤡
Love the video and the project. Props to all of us DIY guys. Question though: doing it manually at home by hand... my concern is that you'd end up with slightly different sized ports just due to human error and "eye-balling it". I wonder if there is any way to measure each port to make sure they're as close to identical as possible?
My thoughts as well
That's effort and commitment right there. Not sure its worth the effort, most of us don't have the tool or confidence/expertise/steady hands but more importantly, time and patience to do this!! esp with its questionable gains.
But its the first time I seen one go to such extend for their car and 'free horsepower', But I am sure it was worth it, cos inside you will know you are one of a kind and probably the only 370Z roaming the streets with a smoothed out inner manifold! haha~
I had a g35 vq35.Port matched the lower to the upper.Used paint to outline one on the other.Good result.😀
Nice 👍 Happy to hear it came out nicely!
I liked using the Dremel. Worked perfectly.
This sort of port and polish work is SOP for anyone serious about race track driving and racing.
For intakes, please go with AdminTuning and dont waste your money with the others.
I like all the experts commenting on this, is hilarious 😂
Something that I want to mention is that the plastic didn't get any smother at the end, and that can affect the airflow, if you don't have the willingness or the patience to go all the way and sand down to a polished look the plastic, you could use a heat gun to "melt" the rough surface that you got left with!!
You really don't want a polished intake track. Tons of articles on why you want it non polished. Exhaust ports you polish but you leave the intake ports just ported out.
@@1330dai I'm pretty sure that on port injection you can polish the ports before the injectors, as it will accelerate the air flow in to the engine, but you have to leave them rough-ish beyound the injectors to help the mixture atomization as for the exhaust the only advantage of a polished surface is to get the carbon build up delayed.
Melting would just cause more irregularities bcoz no way could u do it uniform like sanding but u only have to go to a certain grit not mirror finish like factory just think what a alloy one looks like inside they are not mirror finish &i know for fact going mirror polish on alloy in a plenum can actually reduce power as there needs to be a little roughness to encourage a swirl effect for better air/fuel atomisation then straight turbulence the only free way is if u know how to open the ports just enough to make power too big but n it also has a negative effect then port match everything same as the exhaust manifold n exhaust ports
Enjoy your 1.2 hp extra
I would be surprised if its that much
Also possibly a lean check engine light.
@@nightracerx Why would it become leaner you dumbass?
@@kiyoponnn Why wouldn't it? Dumbass.
@@nightracerx lol. yeah. no.
He did remove a fair amount of material and smooth out the transitions nicely I'd guess the intake mod alone is good for 6 whp with another 4-5 ft lbs trq.
Nice guess, but probably more like 0.6 hp.
@@thequietkiwino you actually gain around 10-20whp all across the powerband with performance drop in filters and exhaust components.
Quality labor
I think you had an o-ring gasket but, you should be able to make a template for the gasket match in order to open it up some more.
Good job 👍🎬🇬🇧❤️
Very impressive 👍
Thank you Jeremy 👊 Cheers!
If you install new headers (cat-deleted) and new mid-pipe (cat-deleted) like you mentioned but cant afford to replace the stock mufflers (catback) will you still see a performance gain? I just want to know if this route makes sense cause I thought the mufflers where only an auditory gain for sound and not much more performance compared to the other part previously mentioned?
It might improve performance, as the cats are stealing some hp, but that it's illegal almost in any country, unless it's for track use, I'm sure you would gain more with a bigger bore exhaust then the stock.
In most cases, the mufflers are just what they are called, mufflers, but the stock ones are quite restrictive, depends on the model, they can have the pipe shaped in "S" or whatever, so it takes more time for the exhaust to get out.
So do you do any shaping down in the port or just smoothing?
do i need to buy the sand paper rolls or can i just use normal one and make it at home?
Obviously some people have no idea on idea on flow and port and polishing? It's like 2 engines. One is blue printed. And one is assembled roughly. A blue printed engine will perform a lot better than a non blue printed engine. Common sense! Same with port matched intake ports and exhaust ports!
Cleaning your evaporative system, valves and lubricating throttle body passages will be a so MUCH better job that this.
So for this to work right on a newer car you then need a tune? Right?
If you have a VHR 3.7l 370z or g37 just put a 3.5HR intake manifold on it… motordyne basically sells a m370 manifold for over $500 for the 3.7 and all it is, is a 3.5HR manifold with some stickers lol
What if you have a Hyundai with built-in doors on the runs on the upper intake manifold.
Wow...lets do a dyno test to see if added 80 bhp or 120 bhp..!
Well, I was actually expecting more extreme porting job. But yeah, smoothing out maybe also work.
Hi Milan. I own a Hyundai Genesis Coupe 2016 with a V6 3.8 liter GDI engine. Is there an easy way to inspect valves to know if they have carbon build-up to prevent a possible useless and costly clean-up expense? Thanks! :-)
Get a probe camera, remove the spark plugs and get the probe into the ports. The footage will reveal the condition of the head and valves.
Trust me, if you have even 20000km on that motor you have sever carbon build up
If you have a GDI engine you already have problems.
Just block of the egr for a start
Dimple porting intake manifold gives power
Very nice job. My brother has been building performance engines since he was 23. He is 62 now. It all adds up a lot. I've been in some of his projects before and after. Damn big difference. Top job btw! Cheers from Australia just subbed.nice work.
Thanks brother! I appreciate it. Welcome to the channel 😁
You will "visually" see a difference but you only accomplish a super minimal (not measurable on a dyno) difference in HP. You are dealing with a run of the mill daily driver, not an all out performance engine. There are much better ways to spend your time and money to increase true engine performance.
My tip for greater power gains than this is to compound your paint then polish ( weight reduction) 50 bhp at the wheels my arse
Are there any other hidden, not as known things you can do to bump up the power in your car? I have a 2010 Chevy malibu with the 2 4L ecotec engine and there arent a whole lot of mods and stuff for it. I can really only get a tune and a cold air intake besides doing porting and stuff
You'd be much better off working on the suspension and brakes, and try to remove a bit of weight.
with this you make only 1hp more ! lol . buy a chip
EVERY LITTLE BIT COUNTS!!!
Fisnik Bunjaku and you could f up the intake mani. It's a worthless mod.
@@Sergiosniper100 No, not always. Why run the risk of fucking up your shit for 1 hp? You'd get a much better increase by leaving the spare wheel at home.
how much would a shop charge to install this
How much HP did you gain out of it?
I respect the effort... but for the work... it’s pointless. More on plastic ... then air dynamics and Venturi effects yada yada take effect. A drop in k&n filter would net more power
Is this the same thing Z1 does to their manifolds?
Yes
manufacturer should be doing this
Hopefully you got dino result before and after
More power baby
yes more air more power but y’all make sure you get a ecu tune
Hmmm!!! 0:17
MOH POWA BABY
You need to look at the choke point, meaning the smallest point of flow. Your valves are way smaller than the port, the points that you made in this video are related to cars that had fuel and air mixed, you have direct injection and this did nothing on this application.
The vq37 is port injected... actually do research next time.
5+ hours of work to gain 0,5hp
Maybe less.
z1 motorsports ported manifolds are probably ported better
Are the gains worth all the work?
That's up to you. I think so, but most people don't like putting work in on their cars for smaller gains.
I strongly suggest you get ahold of admin tuning, go with their 3in intakes !! He can even do a mail tune but the man knows his stuff when it comes to these Z’s and G’s
Get admin and get gapped
How to change automatic transmission fluid on a mini?
Step 1, swap out the automatic for a manual ;)
milanmastracci I totally forgot.. your mini is a manual . Thanks anyways
You should put some WD-40 on a towel and rub it on the intake runners to make it smooth🔥but great vid as always🔥
With more air, you need more fuel proportionally
Exactly
You are correct, however most cars' OEM fuel systems are not close to being maxed out.
Doing this by itself isn’t going to make any difference, especially on modern engines. Usually this is only done if you’re using oversized valves/wilder cams.
it milannnnnnnnnnnnnnnn Sweeet
I think putting it in the dishwasher prob get you 3hp gain lol
I got both upper n lower from z1
Hey bro ,do they make a difference
What about if I just get the upper , will I still see gain
Get tuned by admin tuning!!!
And then get gapped by weak ass tuning he does
This only works on cars that aren't computer controlled
I could do that to my tahoe 2011
Wet sand it then wax it. Use ceramic coat
Don't forget to take a poop before driving for weight reduction
Hey man fuck these haters this was a great video and I’m going to be doing this on my G37 coupe along with isr longtube headers, SCS 3” single exit, Gtr injectors & aem 340 fuel pump to run e85. (Already have longtube intakes)
I seriously doubt this does anything major
One way to find out :)
Make him money on youtube
Not even a port and arguable if it can be considered a polish...
Yeah how much hp did he gain from 7hours of work
Free power maybe wanna send me a new car?
I don’t understand how this really does anything lol
Yup let’s waste money on a tune after this.
This wont give you a single hp, dont recommend doing this. A free to "increase hp" guide is to clean your throttle valve, check tire pressure..
Milanmastracci, when I saw you polishing the plastic “imperfection”, I realized if hundreds of people watching this would do the same job and waste their time to gain 0.66 hp with a potential risk of contaminating the intake system.
My advice is DO NOT do this procedure!
Well I will be doing a couple Dyno runs with the car as is, along with how it is after some these installed.
If you are that desperate for 1.5HP your better off going on a diet 😂
I cleaned my ashtray and my car is 30hp richer...
This will not increase air intake all you have achieved is reduced very minor turbulence WTF I agree with
Itsjusta VTEC
That’s a ton of work for ZERO noticeable performance gains.
Nothing you’re doing there will demonstrate a statistically significant in crease in HP on the Dyno.
“Smooth” does not equate into power. Especially if you decrease velocity.
I’ve seen more intake manifolds destroyed by professionals “porting and polishing.” Sure it looks great, but they all too often destroy velocity.
Without a method of flow testing your intake while modifying; leave well enough alone.
👌
At least port it. What you did will net you 1-2WHP
I feel like this made no difference at all.
Dont. Just dont.
Your car is nice and all but the Nissan is still pretty primitive not my choice of vehicles sorry
How could you show this to your viewers? Think you are out of content.
What do you mean? I understand people are not made of money, however by doing this porting process, you should be able to make your car faster without purchasing a mod, like an aftermarket intake, etc..
There are companies selling pre-polished intakes for thousands of dollars. He's doing people a favor.
Why didn’t you show us how to remove it man ? Come on dude please
Dropful take the bolts out and lift... if you don’t know where the bolts are then you shouldn’t do this because you need more research. Learn your engine before you play with it.
Do you even have a 370Z???
not free, for cheap. :P
not feel or make a difference
Mate lets get real the gains can't be anywhere near 0.5% with this procedure and anything below 10% won't be noticeable out driving.
😂🤣
That’s a lot of work for very little gain in HP!!
So much effort for negligible gains.
3rd
Don't tune and map your car just go buy a car that is designed to give you the power you want.
First
Don’t care ^
