Question Can a FAST 90 mm Intake/TB be ported to 100 reliably?

If so, which sponsor would be an optimum choice for the work along with Vengeance?

Or does anyone sell a 100 mm throttle body?

Thanks!

I could only open up the snout of my Vengeance ported FAST 90 to just a tad over 92mm. I wouldn't think you would have a chance of doing that on an old FAST 90 because you will run into the "O" ring channel. Now the FAST 92 might be a different story, based on my single experience with the 90, you could probably port the intake snout to take a 95mm. Hope that helps.

Damn. That sucks. Guess I'll have to bite the bullet and get the new 102 FAST

THANK YOU!

That's exactly what I'm looking for


EDIT: Forgot the new 102 isn't compatible with cathedral heads Guess I'll have to call Ron and see if he can port my 90 to 95 and buy a 95 mm tb.

I just wanted to have 100 mm straight back once TSP's 100 mm Lid and MAF are on

We have done a few 100mm openings. Can only be done on the 92mm intake though. Also, you will lose your O Ring to achieve the 100mm. We use a paper gasket with RTV to seal the intake/TB... Several people on this forum have had it done and it seems to hold up fine.

Give me a call if we can help you out.

Ron is correct, the 92 does open to the 100 and the results are good to date.....just need to do the gasket by hand.

Has anyone picked up anything from going from a 90mm to a 100mm TB? If so, who? I would gladly do it but I have heard that the 90mm will support over 1200 hp without restriction.

I'm an LS7 guy that has one of your throttlebody's but that doesn't mean my opening is at 100mm. I haven't heard of anyone doing it yet.........not even Vengence.
