The stock Z32 TT fuel pump is good up to 700hp, so it's not a pump issue. Unless you upgraded to 555cc or higher injectors you will max out the stock 370s around 400hp.
Have you bypassed the factory fuel pump control module? it will hold you back from running full voltage because the wire is too small especially with a bigger fuel pump.
Hi, Can we get an update? I imagine he has since had time to look into the problem and back to the dyno? The OEM 300zx TT pump is said to flow around 380lph so if it was working properly it should have been more than up to the task. Was is a faulty pump, Voltage draw or the fact that base pressure was set too high? None of the above?
lol. Couldn't figure out when and why I'd subbed to this channel. Looked back at the channel's vid history and realized it was for the blown E55 a few years ago. This is really awesome content. Glad I re-found it.
On any upgrade always do the fuel pump on an old car, they are so cheap now. Plus your lack of using knock ears on the dyno is a worry. Lets hope you haven't damaged that engine significantly.
10:10 Bosche 044 You're working with a close to 30-year-old pump. The factory one will make an easy 540 whp if it's brand new but the best way is using the factory pump as a lift pump to a surge tank and then a bosch 044 pressure pump. You don't "need" a surge tank in a road car but for the small amount of time and money it takes to fit it's well worth it.
I bet you at some point the fuel pump failed and was replaced with a na one (as long as the car runs stock boost, you would never notice) it's a cost efficient way to get it back on the road. Na fuel pumps max out around that power range. I'm running 500+ on a stock twin turbo fuel pump without issue. Just a wild guess
How u set the variable valve timing? I hope u do advance timing from 2k rpm till redline... And next another run without timing advance from 2k rpm to redline... Then u will be able to combine 2 graph and select middle ground swichover point for the valve timing...
In the early 2000s my bro was going to buy a fairlady ..my friend was a tuner and had a dyno we asked him what he thought and he said if you buy it get someone else to work on it..There is literally no room in the engine bay..this video really confirms what he was saying all those years ago
Thanks for the heads up about the fuel pump/regulator. I've heard the same thing about stock fuel pumps able to support huge HP numbers, but it looks like maybe that is outdated information (maybe it was true years ago when these cars were younger?) or it's just an exaggeration. Great video!!!
It’s not outdated. There’s a “cheat code”, so to speak, in regards to the fuel pressure sending unit within the pump, where you can put a bolt into a flange or something and hold a spring in place within the pump to withstand up to 750WHP. I can’t recall the specifics in detail, but I know that Supra guys were doing this with Z32 TT pumps quite often back in the day.
Stock fuel pump isnt that big . You need to check what people are telling you. But good to see you kept with the vg30. Check out rwpracing for proper vg30 power.
I wonder if A Taurus SHO (Yamaha 3.0, 1st and 2nd gen) intake would fit on that? Never really looked at a 300ZX intake manifold before. It wouldn't do any good for a turbo/twin turbo setup, only NA. Maybe a custom lower intake manifold adapter. Short and long runner intake to keep the air velocity up at low and high RPMs. It'd be a trip to see under the hood of a Nissan.
6:00. Run some basic screen saltire software on your laptop and show the values as an overlay on the screen. We can hardly read anything on your laptop haha
That is weird... I have 740cc injectors, 3" exhaust from turbo back, intake and rich chip tune. I had it run on the dyno and it made 377 WHP, that is with stock turbos and fuel pump etc. Not sure what is going on here with the fuel, but my mods are nowhere near this and I made roughly the same at 15-16psi...
The previous dyno sheet of this car on stock turbos said 360hp. I told Seb it was complete bs. He didn't believe me then but after driving the car with 380hp he can't even put his foot down. He believes me now. A lot of shops over calibrate their dynos to give optimistic numbers and make people happy. This dyno I believe is very real. Gives dissapointing low numbers but very good laptimes
@@xfmotorsports Interesting, that the guy that ran the dyno in Washington State "Drift Office" told me the same thing about his. Either way, running out of fuel isn't usually something that is common at this power level unless there is an issue with the pump. I know that the TT pump has a 2 speed pump controller compared to the NA. I am not sure what the ECU is doing, as it is standalone, but could that be related?
Also, a curiosity of mine, since this is using a MAP setup I assume, is there a reason that the 90 degree bend before the single intake is necessary? That is a known restriction and solutions that use a dual MAF and a translator (Selin) are often used when on the stock ECU. With MAP, I was wondering what would happen if that Y piece under the nose cover was replaced with two air filters on the turbo inlets, eliminating that restriction. Note: Visible as the green filter at 3:15 Another thing too, those foam filters are mostly NOT recommended because they get old, stop working and break down, letting chunks of old crusty foam into the intake. I had an old TT I was working on that had that same filter media and it let sand into the intake...Needless to say the engine ended up being toast.
@@xfmotorsports thanks! I've got VG30DET running over 8000 rpm for a half of the season, and then 3-rd rod bearings got bad...so now i try to figure out, was it the knock, oil starvation or exceeding of RPMs...
by the way...drop of fuel pressure in your video on dyno can be just because of the bubbles in the fuel return line if the tank was 1/2 or less filled.
Just don't go above 500 crankHP. I did some research on that motor and if I remember correctly the block like to split apart at 500 HP. That's why there weren't too many high horse power 300zx's out there. Even built the motor would not stand more than 500hp. I wanted a good Nissan motor for an early project car and could get one of these motors really cheap. But then found out that they were fragile, so I passed on that motor.
yeah thats just not true.... these are pretty stout motors.. ua-cam.com/video/e6UhQDD_oRs/v-deo.html the things that ruin these engines are cheap upgrades and bad tuning.
Your fuel pump might be an N/A pump that someone switched in at one time not knowing it was N/A, to save money, or your fuel filter might be clogged. The standard TT Fuel Pump can handle 740WHP brand new.
Your pump is most likely fine. There is a brain....behind the drivers seat that controls the pumps output under load. That is most likely your failure.
Channel wise, I believe he is going the wrong way with the content. The videos over the last year have been quite bland documentation of working on regular cars, or doing way too technical and detailed, boring things on a few, somewhat interesting cars. It's hard to explain really, but considering the limelight he had with his homebuilt racecar series, he hasn't really recaptured that sort of attention again. He kinda let the E55 ASL project fizzle out without ever really finishing it and that was a letdown. There are thousand other channels that do headbolt replacements or fix random cars. There WAS only one channel that documented creating a detailed and engineered HOMEBUILT RACECAR. That was his ticket to youtube success. Considering his latest "F1" build, I hope he has realised that aswell. I wish him nothing but good fortune, but am just kinda disappointed in the direction the channel has gone.
As an engine builder from the USA I wish I could work with you on these awesome projects!
Anxiously awaiting your f1 style project, planning to start a similar project in the near future!
Man I love this channel. This is hard stuff. Would love an update on the manual swap e55 if you worked out the electronic issues.
Agreed! Compared to most other car channels XF is straight rocket science.
I love watching busy pro's share their expertise with the rest of us. Great projects!
The stock Z32 TT fuel pump is good up to 700hp, so it's not a pump issue. Unless you upgraded to 555cc or higher injectors you will max out the stock 370s around 400hp.
If the injectors being small were the problem then the fuel pressure wouldn't fall like that.
Looks like they went with the yellow top injectors. Should have went with the red
This guy is exactly what I would picture in a 300zx owner. Bluetooth ear piece and all.
17 psi boost is always the peak magic number on these 90's japanese cars with stock fuel pump ;-)
Kind of sad because of fuel pressure issue but also happy knowing we will see more of this outstanding Nissan beast :D
Any thoughts on the freevalve stuff Wesley Kagan is working on? The two of you seem very similarly minded
Just dyno tuned mine for E 2 weeks ago. And yes, a walbro 450 provides more than plenty fuel.
Have you bypassed the factory fuel pump control module? it will hold you back from running full voltage because the wire is too small especially with a bigger fuel pump.
hey great channel, youtube needs more 300zx content like this! I am also looking at putting a haltech in my z32

In a week or two

The intake air filter is pretty much right behind the radiator, wouldn't that be the opposite of cold air intake?

Na fuel pumps max out around that power range. I'm running 500+ on a stock twin turbo fuel pump without issue. Just a wild guess
I wish I could bring my E55 out to Canada for some XF mods 😁
Great video as usual. Can not wait for the F1 project to get going especially the chassis build. Really excited
I’m currently building my 300zx abs man is it a pain in the ass lol good luck
They are called lorinser wheels on the s63
Updates? Hopefully upgraded fuel system resolved the issue!
The way the guy said “i seen a flame” had me crying
300hp crank to 380hp at the wheel is a big jump, no wonder it felt good.
380 on wheel is maybe 420 on crank?
Very excited to see that m113 dry sump system.
What is the update on this 300ZX TURBO? did he get a new fuel pump she achieve 500HP? WE NEED AN UPDATE VIDEO!
I can't wait for the next F1 build episode
How u set the variable valve timing? I hope u do advance timing from 2k rpm till redline... And next another run without timing advance from 2k rpm to redline...

Hello - did this car ever return to the dyno with the upgrade fuel pumps?
Awesome and crazy as usual 😋
Thoughts about doing toyota getrag r154, v160 and/or tremec t56 adapters for the m113,119 and m120?
I love this channel. Much success to you brother.
Such great content, originally came for Mercedes content, but everything else is gonna be worthwhile for sure. And dont forget your Namaaz bro lol
Great job!
About the F1 engine will keep it opendeck? With all that boost inst better/safer make it a closedeck?
The turbine wheels of the matte grey car look inspired from the one on the SLR
great update !!! excellent channel

Why don't you get a e85 fuel pump so u can tune for that n put a map sensor n air temp. I had a issue when air temp was getting hot
Is that the original fuel pump or was it a brand new OEM replacement? I also heard that they should be good for 600hp
I woke today wondering how things were going in the XF Motorsport garage. Good timing I guess
The wheels on the Mercedes are Lorinser LM6
I hope you have changed or at least checked the fuel filter. If it’s clogged it will kill power significantly
Realistically around how much did you waste?
I have a doubt which year of 63 cars change from the m156 to the m157
Excellent content! Keep it up
Hmm!! Only 380 hp!! Looking forward to seeing what the uprated fuel pump does to boost the hp.
The wheels on the 220 looks like the brand Lorinser
when is this going to be dfinished?
What do you mean by "igniter" ?

Could be different dynos, different fuel, different engines, a lot of variables.

Great job man
I have 1996 Nissan 300zx twin turbo I need upgrade please
Wheels are Lorinser Rs8
Meh. Need to go to side mounts, and Geeze with the Haltech and those turbos for dual intake. Leaving a lot just in those mods.
Please say, what is the maximum safe RPMs on this engine (VG30DETT) ?
Power starts dropping off after 6500rpm. Redline is 7k. I've heard people taking it past 9k but not sure what their mods were
@@xfmotorsports thanks! I've got VG30DET running over 8000 rpm for a half of the season, and then 3-rd rod bearings got bad...so now i try to figure out, was it the knock, oil starvation or exceeding of RPMs...

It does.

God your so wrong.
yeah thats just not true.... these are pretty stout motors.. ua-cam.com/video/e6UhQDD_oRs/v-deo.html the things that ruin these engines are cheap upgrades and bad tuning.
Mine over 650whp for years.. what are you talking about
Those wheels are made by Carlsson.😁
Finally
What do you use for knock control?
his ear and possibly a knock sensor
Your fuel pump might be an N/A pump that someone switched in at one time not knowing it was N/A, to save money, or your fuel filter might be clogged.
The standard TT Fuel Pump can handle 740WHP brand new.
Isn't this the exact same 300zx from wheeler dealers?🤔
Bloody hell 😍
Why do you have a Russian secret agent helping you? The ear piece is a dead giveaway!
You shouldn't just rule out the fuel pump in general, because it didn't work for whatever your setup is. I'm make well over 600whp on a stock TT pump.
As good as it gets... Ho do you know all this?
Never know if Sebastian is on a call or not.
I have been waiting for this video. Love the channel.
The “cool” wheels are SLR replicas mounted the wrong way around. Cool... :-p
You lost alot of your lisp, good for you man
Maybe the fuel pump is Just old and make not the original power
That desk fan doesn't seem good enough for a dyno
Your base fuel pressure is WAY too high! Base pressure should be 43.5psi NOT nearly 65! That’s why you’re running out of fuel pump!
If he is at 20 psi of boost, wouldn't he be near 65 psi for fuel?
I cant believe yall didnt at least put a wahlboro fuel pump in there that's a must for more power more fuel OEM is Do Do 💩
Hellcat fuel pump will do the job and they are cheap .
👍💪💯
Your pump is most likely fine. There is a brain....behind the drivers seat that controls the pumps output under load. That is most likely your failure.
