Need 2/10ths I have a full weight manual 72 chevelle 370ci ported heads, johnson link bar lifters, headers 3in with xpipe, ls6 intake stock TB, vortech v-3 si 3.4 griptech pulley 9-10lbs at the top using air to water intercooler. 275/50r15 d.r. adjustable coilovers. Best time so far was a 3k launch to get 12.10e.t. @ 111.98 . What would be the best purchase to to help get me to 11.99 just to say I did it!

Agree on what's the 60ft? You need to leave in boost. What are you shifting at and what cam and was it degree'd? What compression ratio? You're missing at least 10 mph if that engine setup is healthy. Did you dyno it?

Shifting around 6500 and a jam cam was the recommended. Not sure about the tune someone did it for me. Had initial problems with belt slippage and a lack of intercooler which has been fixed but never went back to know what the final info was.

what kinda of mph at the track or even h.p on a dyno should I have so I know what to look for if the tuner can look at it soon. I thought a 1.8 was good but you guys are saying i should be in the 1.6 range?

wait a minute ....
you bought a boosted car ....and you don't know if it was dyno tuned or have any numbers ?
if that's the case, get that bitch on the dyno ASAP and stop going WOT. I mean really it shouldn't be driven.
it doesn't take much to blow the motor. just one lean run with too much timing will pop it FAST.

It's an auto, but has run 11.60's @113. And I think his mph is a bit low. I'm sure it's every bit as heavy as your Chevelle.
I'd bet given what you said, it has no timing due to no intercooler. Or does it have one now?
I assume pump gas?
What EFI system?

During the dyno he only ran the motor up to around 3k and said its slipping and hot intake temps forced him to shut it down. Was told the tune he made should be fine for a basic setup like mine. I've changed the style of tensioner and installed an air to water intercooler since. Sounds like I need to get back on the dyno. Oh it's a holley terminator
