This car ran 11.83@123 .....launching at 1600 RPM

This is from May 1992 mag...the 1989 Snakeskinner 1

Yep but who did the work? I cannot remember... I guess JVD would know unless you do...

If you go down this road to Siamese , make sure you have someone who know what they are doing........ this thing cost me major $$$ for the plenum, work done, then GVD to fix it...



Hey Todd

Sure would like to see those double DD's

I have only seen the single D

[RHanselman]

You know, GVD was probably the guy...

Hey Al

It was both that Greg had mill flat.
I bought all new plenum, and housings, sent out for siamese runners got back a wrapped used mess from Kirchhofer. I sat on it for a few years then had Greg Van Deventer port it and mill it all flat. So I bought new parts, got used parts back that would not seal, then Had the right Guy fix it.... This is why I say " go to the right guy first ".

I've never heard or read of anyone doing a flow dynamics study on
the LT5 intake. I'd like to hear more about how this would be done.
(specifics)
As for before and after TQ & HP numbers, yes I've seen them years
back on a HI car called the Pineapple Express. They were posted on the list server (mail list). I can't promise to find them, but I'll look. As for the stock numbers. They're out there in spades.
