I recently built a new motor for my car, including PP LS6 style heads and the 231/237 cam. It was tuned by a very reputable tuner. It is an M6 on street tires, and race weight was 3685. It was running consistent mid 116 mph traps, and 89 in the 1/8. That seems low to me. With stock heads, a little TR220 cam, and basically no tuning it ran 90 in the 1/8 and 114.5 in the 1/4.

I would like some thoughts and opinions as to what it should be trapping. I am not worried about the slow ET's as the car has a stiff autox/RR suspension and a light flywheel/clutch.

if your suspension and tires are right you should be in the 120's

well lets see you ended in 3rd hitting off the rev limiter so we'll start there, whats your rev limiter & where are you shifting? 3.42 gears i assume, and you bogged off the line...you probably lost some mph by bogging off the line, another 1-3mph can be made with 4.10 gears & have your shift points at 6600 or higher to be effective with a cam that peaks @ 6300.

RWHP from smokemup's calculator is 394.2 RWHP ...

Car still has 3.42's, limiter is at 7000, I was shifting at ~6700. The car is not set up for drag racing, and I have not done much drag racing in the past 5 years. Weather was about 90º and a little humid.

In good weather (50s no humidity) my car traps around 117 with 400 RWHP. That is at 3650# raceweight - you gotta factor that too!

In 90 degrees and humidity, I am trapping 114ish.

Wow, that calculator was off by only .01 for me.

I ran a 12.91@105.5 @ 3455 raceweight

It claims an 11.35@120 on the spray.I hope to find out this weekend.
