My brother's driveway built LSx Iroc at the track putting it's new power to use. Kept getting faster and faster each pass until track officials shut it down for lack of a NHRA rollbar.









It's still spinning off the line and he's finding the shift sweet spot. Once we get it sorted it out, we're shooting for a 10 sec 1/4 mile.

Awesome! Can't wait to get back to the states so I can play with my Ls1 T56 Iroc... What's all done to it? Cam, exhaust, tune...?

I'm not too far behind with the 388cu

There's a bunch of sweet LS 3rd gen running around SoCal these days.


Mild BTR cam, custom true-dual exhaust, CMS dyno tune.

7.1@97.7mph vs 7.9@91.5mph is a pretty big margin. He shifted early on these runs, it'll do 6.80@100+mph if he shifts closer to 7,000 rpm.


You do have an impressive 1/4 mile trap speed for a TPI variant

I know about the 1/8 mile speed. Currently working on it. It going to get better with time. Give me a couple of months. I'll be close for a mild build.

I'll head out to fomoso soon get my launches down and find that perfect shift point. 2nd time out with the new set up, waiting to weld my relocation brackets for lca and adjust pinion angle. Not bad for a lowered car and a/c equipment

Yeah! Give me something to shoot for
