Are these available for the V6? Figure it would be a nice simple bolt on.

Any Ideas?

 

there is nothing available right now. i have built one for my car but i haven't run it very much yet. once i get some run time with it, i am considering making more to sell but i want to verify that my design has no problems.

 

Hey guys,

There is a guy who bores out throttle bodies. He charges about $150 bucks and will bore it out to 57mm. He does this currently for Fiero throttle bodies, but they're not THAT different from a Camaro / Firebird 3rd gen V6 throttle body.

He also said that he has done a couple for his friends before.

If you're interested, shoot him an e-mail.

i don't think that there is enough meat in a f-body TB to bore it to 57 mm. i have an extra stock one out in my garage that i was already planning to bore to see how big i can make it. i'm thinking that i might only be able to take it to 54mm, but, we'll see. of course, that 2 extra mm calculates out to over 30cfm...

 

Whats the bore on Stock TB?

Hey,AM91 Camaro,If you get to selling the TB's..How much you think they would cost?

 

How much Extra CFM from stock to 54MM?

 

Stock is a monoblade 52mm.

 

Stock is in fact 52mm= 308cfm
FDP made a 62mm=435cfm, but will not work on the stock intake plenum. I tried to taper port a stock intake to work with it but was not happy with the tiny lip remaining to seal the gasket area between the TB and the plenum. I would guess about 57 mm would be the most you could port the stock intake for a smooth nontaper flow.

The FDP 62MM TB's were discontinued due to lack of sales.

 

i don't know yet how much i would sell the bigger TBs for. i want to get some run time on mine to make sure that there's no problems before i even consider, very seriously, selling them. i am guessing an extra 30-40 cfm going from 52 to 54 mm.

 

62mm TB attached to a stock plenum ported max to fit. I did npt want to try and port the green section any thinner than I did because it was just getting too thin. I did prt material off of the plenium about 4 inches up inside the plenum from the TB lip, but I just did not want to make the rest of it any thinner to match the 62mm. I only ported the 62mm at the tapered lip I show and realized I am running the risk of breakage or even porting a hole right into the casting walls- this is when I decided to build the new plenum.

The blue line shows aprox stock plenum wall thickness.

 

Only 30-40?

Thats like barely any Power Making potential.

 

30-40 cfm is only my guess and that's only with 2mm. 2mm isn't very much. now, if i can go 5mm bigger on the stock unit...we'll be looking at quite a bit more flow... my new 65mm SHOULD flow close to 600 cfm! of course, that's going on a 3.1 with a lot of mods! i'm a little worried that it might be a bit much but we'll find out pretty soon, i hope!

 

Looking forward to results..Dont forget to post em

 

if they're what i'm expecting....i will definately post! lol.

 

30 cfm is quite a bit when you consider the size and requirements of our engines.

 

Would there be any modification requirment to this performance TB? Modified Intake/Plenum etc..??

 

nothing would be required but some porting out of the neck would be beneficial.

 

A stock 1985 MPFI unit works very effectivly as is mated to a 3.4 mill.
One wants to increase outside cooler air to stock MPFI set up.
One wants to exit exhaust fumes better than a stock exhaust set up (my current weak area of my combo).
One wants to ignite fuel stronger (to take burn more fule) than stock ignition set up.
My engine a 3.4 swallowed all these goodies (except exhaust) and it works very well using a cleaned (not ported) out 1985 MPFI unit. And I'm running the more restrictive Firebird air cleaner intake set up, too.

I just setup the TPS on the 62mmTB and RTV'ed the TB to the ported stock extra plenum I have- going to try it out on the 2.8 tommorrow if I get home early enough to see if it will render any results on a basically stock motor.

I'll post results when I try it- by this weeekend for certain.

 

awesome! you plannig to go run some laps with it on there or are you just going to go by the good ol' seat of the pants?

 

You're using the stock strong 2.8
Give a shout about your results!
Totally peaked my interest!
I can only say the stock stuff, "works just fine" ontop a 3.4 mill.
My only limitations I feel is the stock exhaust system I run.
Yes I am using a 1995 Camaro AC Delco Cat Convertor & a Ansen Z-28 exhaust muffler set up, to help.
To help. Stock is so restrictive.
How I can't wait to install the PaceSetter Street Legal Exhaust system. Your ride has the headers, too right?
