All bolts ons plus GM 847 cam = times in sig. Full weight car, heads never been off the car and are completely stock in all aspects.

 

dont be mad.it also depends on the track among other variables.

 

well i did use a mail order tune so that could be some of it.

 

M6 or A4? M6's usually trap much better than A4's.

 

m6

 

Wasn't your 60' something terrible

Get some good tires on that thing and try it again.

 

2.2 60'

 

What exhaust are you running.

 

hooker aerochamber with dual cutouts and jet-hot LTs

 

Might want to consider a true dual setup from Doug at Performance.

I think he was around $250.00 for the whole thing.

You could have it as just a track exhuast?

 

performance is who put the exhaust on. you think it will make that much of a difference going from open cutouts to true duals?

 

I think so, the motor needs backpressure. I'm not a fan of cutouts anyway. I think most of them disrupt the exhuast flow.

Look at Bryan's car vs Joe's car. Exhuast is one of the differences. Look at the mph difference. They are both auto cars. One traps 3-4 mph more than the other.

I trapped 3-4 mph more with the x-pipe.

 

One thing to consider is that thunder valley sucks.

 

i ran 109 a few times,full bolt on LT1 with an auto et's were 12.36-12.39. race weight was around 3590

 

i went 110.6mph with my old hotcam and edelbrock shorty headers.
