Gains from TB on Cobra?

[98blackmagic]

I was wondering how many of you guys with 4 valve motors have changed your tb's and found a few extra hp. I was considering getting one from BBK but did not want to spend the money for one if I was only going to benifit 2 or 3hp. What do you guys think?

i believe that a 4V will gain more out of a TB than a 2V

I believe that as well, almost for sure. Are you going with just the throttle body and no plenum? I know for 2v motors it is pretty essential to get both to have the power gains (still around 6-8), because one without the other is just bottlenecking each other.

You should try posting a thread in the 4v forum

the 4 valve plenum is not like ours. he just needs a throttle body.

accufab has a 99-01 throttle body it's a dual 60mm unit. pricey but nice it's 390 bucks or so.

Dont they make a big oval TB for those? I seen them put one on a bullitt and it make like 8HP accross the board until the peak which was like 3. It seems like you went mod crazy lol, so apparently you have plent of $$$ burning holes in your pocket. Go for it .

buy a tuner before you get a T/B...Accufab is a good brand but their sh1t is WAY overpriced...

$400 for a TB/plenum combo and 10 WHP max ? What a RIP!

Unless of course your loaded

yea I've spent some big bucks over the past 3 weeks, and my checking account shows it . The tb (if I get one) will go on with the cold-air kit and a mass air meter (if I get one). After those induction mods I will take the snake to the dyno and have it tuned on the dyno. Im just trying to find out info on the parts I want before I buy them.

BBK is 319 for the 62mm and 329 for the 65mm

A throttle body is pretty much a waste, at best maybe a 2-3hp gain. The stock throttle body works just fine on even a 800hp 4v engine. About all you will be gaining is the "bling" factor.

i know several cobra owners who went out and got the TB's and they were either a b1tch to tune right or they just gave up on them and now they made them paper weights
