Throttle Body

CanaryGT · Dec 11, 2010

You think getting a larger throttle body would yield any better results? Im currently running a BBK 65MM...

Mod list?

I wouldn't think so. I've seen people make VERY nice numbers with only a 65mm TB. But as ivan said, it's gonna depend on your setup.

bigger IS NOT always better.

Depends, but 65 and 70mm have about the same results on a light/mildly moded car. 75 can actually reduce hp and is really only used for F/I or wicked engine setups.

I have the same question, would a 70mm or 75mm do better with a 94 Cobra with around 11psi?

It's hard to tell, you'd have to have a dyno to prove it, but as long as the intake is port matched then there should be some higher peak hp gains with the 75 over the 70. Put it this way I'm running a 75 on my Kenne Bell 95 with no problems. Too bad I'm selling everything, time to get a Terminator

You should sell me your 75mm, lol

how big is the hole on your intake. i would get one that matches that size

I have a 302 with Trickflow Heads, TFS1 Cam, Cobra Intake and the rest bolt on mods. Thats about it. Cause my 100 shot doesnt really count.

a 65mm would be pretty close to a Cobra Intake. My TFS port opening is 75mm. I am going for a full 75mm from the intake, elbow and TB to help it flow and not have an restrictions. The less restriction air has the better to an extent
