My Custom GT35R Twin Turbo Z06 - Pics/Info/Dyno Video Inside!
My Custom GT35R Twin Turbo Z06 - Pics/Info/Dyno Video Inside!
The car is FINALLY in running condition. After ten long months, my quest for turboing the Z06 is finally nearing an end.
I went to Sound Performance today to get the car tuned. They spent quite some time (Jerry was great) tuning the Z06 to give it a nice, CONSERVATIVE tune. I am stock block still, so I’d rather be safe than sorry.
So…with .3 bar (4.5 pounds of boost), 93 octane, through a modified but still very restrictive TI exhaust, and on a Mustang Dyno I put down 548rwhp, 511rwtq. I am sure with 3” dual exhaust leading to cutouts I will be able to pick up another 20-30rwhp (those are coming soon).
The new clutch is very very weird getting used to for the fact it catches way up top (need to adjust it somehow) and is about 5 times stiffer than my stock clutch. It is a twin disc and rattles like a mother trucker. Also, one of the seals on my turbos is bad (from the factory – sending it out during winter to fix it). It is kind of funny for the fact an average person would hear my breaks squeaking, see **** coming out of my exhaust, and hear all this random clanking and rattling from the car when it is at a stoplight. They probably think it’s a pile of crap and I beat the **** out of it
I was able to take it out tonight for a few quick runs with my buddy Dave (CobraKalas) and I am sure he will attest…it ****ing moves out! I still have not been able to row it through the gears but wow, I am impressed. I can’t wait to do a 1-4 gear run on the highway tomorrow night! I will def. get video of that and hopefully some races!
Quick shout out to Chris from CM Racing who built this completely custom twin turbo setup. It took a while, but in the end it was worth the wait!
Anyway, below is a link to my dyno pull, a few pictures of the Z06, and all pertinent mod information. Enjoy! I know I will!

Thanks for the compliments guys! I can't wait to build up the rear end/bottom end. The setup was made with 8-1000rwhp in mind for the future. I know I did this build somewhat backward but I couldn't pass up the opportunity to have such a unique setup. I already have an opportunity to have it featured in a magazine 
I updated the video...it now includes a very quick short race against a header/intake '02 C5 Z06. You can see how I just instantly pull
Awais...lets set up a day to race soon! Car still needs a bit of tuning (kept dying on me last night) but should be fixed in a week or so.

Not with those baby turbos. Nice car. Build an LSX block, strap some 72's to it(if they'll fit), and turn up the boost.
