Very Nice. Your MPH is where cc306 & Heads usually run. Extremley impressive. Get some tracktion. Hell if you can cut a 1.6 60' you will be in the mid 11's.. On stock heads....

Awesome times saint! I'll bet those gears help you alot with getting your car into the 306's power band! If my car wasn't such a old piece of crap that keeps falling apart i would go back to the track to get some better times. Looks like you need some ET streets.

112/115 mph is damn fast for both of you
I bet this cold air is REALLY helping.

is your friend an M6?
I *think* the Xe traps lower than the 306 since the 306 revs higher.
Dont u have a 3x valve job?

Id like to see you both with traction
If you guys are trapping like that, i wonder what I'll be trapping with the 236/242
but first I need a cold air intake

Nice times. What were the temperature and the barometer when you ran?

Gives me hope of running more than a 12.5@108.

Excellent MPH!!! Get the 60' into the 1.7 range and you'll have some very strong 11's.

godddaaaaymn

i ran 115.7 with my CC306 .. on 3.73 gears .. not to mention my heads flow 302 cfm @ .600

ur mph is EXCELLENT ! way too high for stock headed LT1 !!!! wow is all i can say ..

my car weighted 3570 when i trapped 115.7 .. though my fuel pump is half dead and is skimping out on the top end .. so hopefully next year i'll be running higher mph with my CC306

btw, i ran a 12.1 on a 1.84 60' .. spun those useless ET streets past the 60' .... (datalogging ur car while doing a run is pretty cool, u can tell exactly how far u were spinning )
