I trapped 112 several times the last time I went.

Mods are 1 3/4 slps, mandrel 3" exhaust, flowmaster, CSI H20 pump, Crane RR 1.6, Moroso CAI.

Stock pulleys, mass air and throttle body. And that is with 50lbs of wheel and tire at each corner

Re: anyone trap 110mph on stock heads N/A?

I trapped a best of 109 mph and 12.61 ET's and that was with all the bolt-on's and stock weight for a 96 WS6 6 spd ( I did have slicks & skinnies on the car). (No cam or heads)

I trapped 109 mph with everything listed above, but I did not have a PCM tune or a cut-out. I'm pretty sure now that I have the PCM tuned and a cut-out with some other weight savings I think the car should see 110 for sure and maybe some 12.30's still a stock bolt-on 6spd LT1

Re: anyone trap 110mph on stock heads N/A?

I'm hoping for somewhere close to a 110 trap once I get my headers on.

Also... with a better 60ft, doesn't that decrease trap speeds?

I trapped 103.98 or something like that with a 2.3/2.4 60ft.

But I was shifting 400 rpms early or something like that (Tach is way off)

I want a 105 trap with a 2.1 60ft... but best I could muscle out was a 2.2 but even then my trap wasn't any better nor was my time.

?

Actually your trap speeds will usually go up with a better 60ft.

Mkent,

I have the 218/224 and trapped 112 in a full weight car, m6 though. I used to have a webpage with all my mods, dyno's, ect but i lost the free hosting. Let me know if you have any more specific questions about the setup.
