This is one of my good friends cars, some of you may be familiar with him "SPDKILZ". He just got it done from having a completely one off custom Twin Turbo Kit Installed and I thought you guys might enjoy seeing it! Here is the post he made on shockerracing.coms website:


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 :D

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 ******* 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!

Can’t wait to get a few races in before winter!!

I'm sitting here shaking my head... that thing is insane! Great craftsmanship!

The guy who built it does amazing work, it just took 10 months to get it done. The guy is like an artist, he has to have perfection when making things. When you pop the hood on this car it is just amazing! I can't stop staring!!!

Holly sh#t, that is the best installation shot I have seen of a TT set up, artist? No kidding - major props!

Great job. Those are some kick butt inter-coolers. That car must pull like a bear down low.

LOL "pull like a bear down low" or a raped ape! Nice job guys!

The car turned out awesome, but he is still looking for a little more horsepower. As of right now the car has a 3" exhaust going back to the stock catback TI exhaust so he is working on getting electronic cutouts in the 3" pipe to free up some power. I think he is also planning to change out the springs in the turbos and get a boost controller so that he can go up to about 6psi boost. He is looking to get a little closer to 600 rwhp on the stock block and rear end!

Really nice! Great pics :D

He just did an interview for Corvette Enthusiast Magazine and I think they are going to be doing a photo shoot in November! Look for the car in the magazine sometime around the end of the year.

Very nice! Thats a beautiful machine!
