Default Stock LS1, 678 whp

I've never made a brag thread, but thought this was worthy. Sorry, no video. Camera man was too scared to be near it during the pulls!






I purchased this car new in August of '99, and I've been beating the **** out of it ever since. I put the blower on about 5 years ago, drove it at 500whp for about 3 years, and then I met Anthony. The modifications have been happening in rapid succession since then. I'm afraid we've reached the limit of my Vortech super charger, and probably exceeded the limits of my stock bottom end by quite a bit, so this is it, I'll be running this set-up until something lets go. I want to see just how long this motor will stay together.

The car made 336 whp bone stock, so I'm pretty happy Anthony and I were finally able to double that. That's not a "glory pull" graph, that's the tune he turned me loose on the street with, so I wouldn't follow behind me too closely!

Part list includes; my all original stock bottom-end with 142,000 miles on the clock-including rod bolts, stock 799 heads/valves, my original rockers, ARP studs, LS6 cam, LS6 intake, AFR springs, stock LS1 pushrods, Fast Track Performance designed fuel system pushing E85, American racing 1 7/8" headers, 3" X-pipe into stock Z06 Ti mufflers

Special thanks to Anthony Peck at Fast Track Performance in Louisville. He's made my plain-Jane blown C5 into something worth talking about. The Kid knows how to make fast cars, and more importantly, he knows how to make fast cars last!

Very nice results.
As I'm sure you already know, the title is a tiny bit misleading though as it's not exactly a "stock LS1" having both a cam and cylinder heads from a later model on it (it is essentially a stock LS6 in a way )...but it certainly is a stock LS1 bottom end and that is quite impressive.

I have run it a few times, but it was about 125 whp ago the last time, and crappy driving resulted in a best 11.0@128. The tranny and rear are stock, so I probably won't make another pass for a few months, I'd like to enjoy it for a while before I have to start wrenching again!

1000's, it kinda thirsty these days. At 55 psi I think Anthony said the injector duty was at about 90%, but I could be wrong, I was too busy thinking about the consequences of 678whp and a stock bottom end! LOL! gas mileage isn't too bad, it's averaged 15mpg around town over the last 2 weeks and that includes about a dozen Dyno pulls.

And yes, the deceptive thread title was just a headline to attract readers!

I approve. I made 700+ for almost 3 years, but it recently the rods let go in spectacular fashion. My profile has mod history and carnage pics. Congrats and enjoy the ride!
