Вставка
- Опубліковано 6 вер 2024
- I FINALLY PULLED THE TRIGGER AND ORDERED THE 56MM BBK THROTTLE BODY. THIS THING IS BEAUTIFUL AND DEFINITELY WOKE UP THE BRONCOS ACCELERATION. JUST ONE PROBLEM. I STARTED GETTING AN ANNOYING WHISTLE ANYTIME I WOULD TOUCH THE GAS. AFTER LOOKING AT FORUMS I DECIDED TO TAKE THE DREMEL TO IT AND SMOOTH ANY SHARP EDGES. TURNS OUT THE IAC PORTS NEEDED SOME SMOOTHING AND BAM!!! NO MORE WHISTLE!! ENJOY!!

I've read about the whistle issue in a couple places. You need to polish (use rotary tool) where the IAC valve goes to eliminate any whistling noises due to uneven surfaces. It needs to have a smooth surface.
I put the Twin 61mm TB on my F250 and I used a Transdapt spacer aswell but I modified it from 61mm's to 56mm's as years back I increased the twin 45mm throttlebody to 54.25mm's in the front[inlet]and 56mm's in the rear[outlet] and also ported the plenum with a sandblaster w/coarse sand then also ported the intake manifold when I changed the intake gasket and saw that the Edelbrock #3881 intake had a 56mm inlet so I ported the stocker to twin 56mm's..
If anybody knows about HVAC you know how fluid dynamics work[yes!;- air is a fluid!!]...With the exception to the 54.25mm twin inlets that I modified to twin 56mm's the 61mm increase then the 56'mm taper down effect increases air pressure..In your case it would be 50mm inlet/56mm flap w/outlet funnelling down to 45mm's... My Transdapt spacer stock was 52.47 inlet that tapered down to 47.53..
The TB has a very heavy set of springs which made driving my stickshift very hard especially after doing the spherical heim joint mod to the pusher rod on the clutch to make it effortless[no more nylon bushing!!!]plus the disc flaps get stuck out of nowhere and adjusting the screw to open the flaps throws my TPS out of whack.Theres no tiny air holes in the flapper discs that help balance idle plus the flapper discs are twice as thick as the stock flappers plus the rod that activates the flappers was stuffed into the housing which is why they set the spring pressure so high also the lower bearing was binding from having grit inside i so I had to take off shield spray out the bearing then use a tiny dab of anti-seize on it before reinstalling the shield..There was no welch plugs to block off the vacuum for the vacuum lines as they just relied on the gasket to totally seal it which totally didnt so I modified mine with JB Weld.Sometimes on occaision the throttle would stay at 1000 rpm's and I thought air controller but turned out to be the flapper rod being stuffed in the TB meaning the slots for the discs to fit into werent wide enough for the flaps but someone at BBK made them fit......LOL..Then after fixing the TB I had to disassemble again because there was air leaks at the bearings that I stopped by using vacuum grease packed into the bearings..
After taking the time to disassemble troubleshoot and modify a $400 part the right way and doing it very similar to the way the stock TB was setup my supposed to be plug n play $400 TB now operates buttery smooth with the same pedal pressure as stock,doesnt get stuck or throw off my flawless shifting techniques and works as its supposed to. but for how long its gonna last is still the biggest question...LOL
Is it normal for a high iddle after installation I when and replace my stock throttle body for a 61 mm bbk on my 93 Ford f150 5.0 but it has a crazy high iddle on it's on
You should order a throttle body from an 01 Bullitt mustang stock there 57mm and you have to do a little porting to the intake. But they fit perfectly.
Or you can get the big throttle body and do a lot of porting to the intake.
Good luck brother I have 3 Broncos of my own and always will 😎👍
Love watching the transformation of your rig! Keep it up, bro!
Where can I get that intake hose set up
You don’t need the carb sticker for the edelbrock manifold
I noticed you have MSD distributor cap. What spec is it to include the what kind/type of distributor, spark plugs, cables, coil, etc...Thank you boss.
Msd cap and rotor kit #8482
Msd ignition coil # 8227
Bump up your cables to 8mm the brand really doesn’t matter they all worked the same for me.
The rest just look up “bronco 6 liter tune up” and it pretty much just gives u a hotter igntion system.
Hey bro I when with a 61 mm on my 1993 Ford f150 and I got a bad high iddle is that normal
That sounds like maybe there’s a vacuum leak. When I first installed it I had to play around with the vacuum lines and had to reroute them.
Thinking bout getting one for my 90. It runs erratic
This definitely fixed my erratic idle.
Where do you find those cold air intake tubes bro
Will that throttle body would also adapt in my 96 Bronco 5.8?
Yes. I suggest getting a little harbor freight dremmel and smoothing out any hard or sharp edges cuz they will produce a whistle sound
what size coolant temp sensor adaptor is that on the upper hose and where did you get that intake hose assembly ?
I got it on Amazon for pretty cheap. Never leaked or gave me an issue. It’s a Dewhel 38mm radiator hose adapter.
Love watching your videos! What is the part # for the Trans-Dapt throttle body spacer? Thank you🤙🏽
Did you ever reconnect your purge valve to the port that is plugged off?
I left it capped off for a bit but the idle was very inconsistent. Eventually I ended up reconnecting everything back to the factory diagram.
Hey man was curious where you got your intake tubes? Also what did you do with your mass air flow sensor since your running 2 tubes the whole way
My bronco is a 90 so it’s Speed Density. No MAF sensor.
Where'd you get the intake with the filter?
Can you tell the difference on HP??
What intake tubes are you running? And what did you do with the sensors from the stock air box? I have a 94 bronco 5.0, looking to get rid of stock intake and airbox, just wouldn’t know what to do with the sensors.
What kind of air intake is that? I heard the k&n intake tubes have trouble fitting on larger throttle body’s
I have a 5.8 1995 if I buy this is it just a bolt on or do I have to buy something else besides the throttle body?
did you put headers?
Yeah It has JBA headers
How long does this take? I’m doing this job tomorrow morning with my friend. Great video thanks
about an hour.
@@SORRYOUTEXPLORING hey man I'm trying to build an intake like that for my f150 could you shoot me a list of what you used ie. Tubes and filter and any other parts. Much appreciated
@@SORRYOUTEXPLORING hi there, last year i bought a 93 bronco with the same BBK and i can hear the whistle, where i have to install the spacer?
Great video!!
Hey what is your air intake setup? Ive never seen that? What is it i have a 5.0l and im going to do the same setup but i was just curious
Looks like there is a throttle body spacer as well what’s that brand?? Be interested in how it effects the MPG. Been thinking about this mod for my Bronco.
Josh Armstrong it's a trans dapt spacer. I'll keep you posted on the mileage
Adventures With Laylay I pulled the trigger and installed the BBK today. Will see how it does over the next week. Do have a little whistle that I’ll need to hone down later.
How much bigger is that bbk than the stock one
around 15 mm bigger i believe.
Damn that thing sounds mean!
Will this work on a stock intake manifold?
It's on a stock manifold when he first installs it.
What does this improve on your truck?
How thick is the intake manifold face plate?
I just ordered a 56MM BBK throttle body for my 1995 F150, it is a 5.0 V8 this bronco is the same engine right?
Same engine. Your gonna love it. Might have to dremmel any super sharp edges or you will get a loud whistle. Not hard to do at all.
@@SORRYOUTEXPLORING awesome thank you!
Whats your air intake setup
S&B Filter. Ford Oem intake tubes to a bbk throttle body.
How did you get the bottom cooling line on there without kinking it?
Gave it some extra hose so I would bend nicely without kinking. It took me a while to get it to route so it wouldn’t kink. Some zip ties helped.
what is your intake set up??
S&B intake filter. k&n intake mount. Oem Eddie Bauer wired intake tubes.
Did you keep the bottom half of the OEM airbox then install the K&N clamp over it to hold the filter??
You can keep the bottom half of the air box on but I removed it.
@@SORRYOUTEXPLORING oh it looked like it was there still lol
If you don't want that, I'll buy from you.
Anyone else thanks anyway
its awesome watching your rig come together man. I have a question on this video though.. I've been looking for a properly sized spacer for my BBK twin 56mm throttle body, but everything I've seen doesn't seem to fit up, its either stock or 61mm... You mention that the spacer is a little bit bigger and works well with the BBK, do you happen to have a part number for the spacer (I noticed in another comment you said it was a trans-dapt spacer, but want to make sure I get the right one)? Also, and you may not be able to answer this.. but I have an Edelbrock Intake I'll be installing with the BBK, do you think the spacer is even necessary?
Since you have the edelbrock intake manifold the spacer isnt needed at all. Your getting plenty of air flow. But I can get u the part number I'f you still want it.
@@SORRYOUTEXPLORING If I don't need it I'll probably just pass, lord knows how much money I've already thrown into the project bronco so one less part to buy makes me happy. I just don't want whistle, not trying to go around flexing on the gas pedal pretending I have turbo hahaha ( had one on my previous truck and that whistle got old real fast). If after everything is installed I have a whistle I'll hit you up for the part number. Thanks a ton for the super speedy response and keep it coming with videos!!!
@@Edirty6 I found a few videos on smoothing out the idle hole in the throttle body so get rid of the whistle. Bbk machines the throttle bodies with really sharp rough edges so as air rushes past that edge it causes a whistle. A 10$ harbor freight dremel took care of the whistle.
@@SORRYOUTEXPLORING thanks for the heads up on that, pretty rad considering I picked up a Dremel last week to clean up tight spots on engine parts hahaha. I'll look into those videos
Hey buddy do you happened to fine some videos of porting that part out
