C6Z vs 5.0 (at the track) Local racing group is doing a top 10 "street car" list and this was a race for the #2 spot. 3 races on a pro tree - I'll admit that I need a lot of practice. 5.0 took home the W.
5.0 is on 13lbs from a P1SC, roughly 640whp.
C6Z is a 10.5:1 427 LSX with a small cam, 1 7/8" headers, MSD IM, CAI, roughly 540whp.
Air temp around 90F, lots of heat soaking in the lanes for both of us.
My runs were 11.0, 10.9, 10.9. First run was a 1.9 60 and subsequent runs were 1.7 60s.

Also my 60 foots were 1.7-1.75. I've watched a friend with similar power go 1.45 on the same tires in his C6Z... so practice is needed.

Thanks! I hit a 132 when I let the car cool down for a while and managed to go straight up from the lanes (no waiting), but all the runs in this vid were 128-129. I think I'll be changing up my Halltech for a Vararam... IATs were sitting on 135-140F by the time I did a burnout, and weren't recovering until the end of the track. Also looking at a flex fuel sensor + injectors so I can mix in some E85.

Nitrous will wake it up even more

very nice op! you got the w on round 2 but round 1 and three were a bit lazy coming out the hole. Imho you won because you obviously reeled him in on all runs. This is why I don't particularly care for track racing though to me the faster car is more determined by a 40 - 130+ roll (real world results). Still all in fun though, nice run

Yep. My 42lb injectors are sitting on around 87-88% duty cycle. I'll probably never run more than ~50% E85 while I'm still NA, but I am thinking I can go 100% E85 and still hit less than 90% duty cycle with 60lb injectors.

Built the engine with boost in mind. Ring gaps are set for boost/nitrous and we went a little lower compression. Cam is a wide LSA for boost. It should be able to comfortably handle about 1500 at the crank.
Yeah we are doing digs on a pro tree because it's about the driver AND the car. Once I get a feel for reaction times and get my 60s down a little, he's going to need more power to keep up for sure.
Halltech will probably make more power on a dyno. However, the Vararam will have ambient IATs even after sitting in the lanes and all the way down the track. I trapped a few mph higher the one run I started with ~95F IATs, so it's very noticeable. IMO for drag racing at a track, the IAT advantage is worth it. If I was roll racing on the highway I'd keep the halltech.
