![Question](https://ls1tech.com/forums/images/icons/icon5.gif)
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.

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.
