That's a neat project. I like that you're using a 4.3 chevy rather than a 3.8 buick.

actually there is going to be a big problem with the exhaust..... its too big!! lol its 4 inch to the bottom of the firewall (no muffler) so im going to see what the open downpipe sounds like and go from there. if it has to go to the axle its going to have to get "CREATIVE" !! lol

Does anyone remember QuickTim's twin turbo Monza?
He built everything and needed only a driveshaft before selling it.
I'd love to have the pics of his build, as I'll be hanging twins on my
car when time and money allow. I'll be aiming for 1200-1500 hp.
I have some turbo Vipers I want to put behind me. :D

BTW, Nice build!

For some reason the video didn't work for me but the audio did. Not very load at all for open pipe but sounds nice.

I've always had the opinion that turbos make EXCELLENT mufflers!

Awesome, nice work!

I've never seen an intake like that. Is it specifically for a turbo appliction?

no thats a crossram for the raised runner bowtie heads.. it was developed for ASA short track.. id rather have a single plane but this one does look cool and it has a wow factor! these heads flow dang near 320cfm, has a roller cam of 224 555 lift, motor made 260 wheel horse NA. so 1 horse per ci NET not too bad. i think 5-7 psi to start will be fun. someday later with a turbo cam and lower CR and (stronger everything of course) i dont think 600wheel is out of the question. eventually i would like it to run low 6's in the 1/8th
