finished the car at 4am friday morning, got up at 6:30am and drove the car 5.5 hours on the highway to get to a HUGE local car weekend. Raced the 100 foot drags where I did not have my boost controller set up properly and therfore got my *** whooped.

But saturday night we had some very fun street action and I proceeded to take down :

69 camaro, Full tub on 33x17 slicks, 502 on the bottle.
Hyabusa not sure on mods I think just a pipe
C6 Zo6 408,procharger -810 rwhp

as for spool time, still got some issues to work out with spooling it on the trans brake but it spools awesome on a roll.

Well I decided I might as well throw the car on the rollers and make sure the tune was half decent for some friday night action.

I was kindly rewarded when the first pull it broke up rich numerous times and still did 600 ish rwhp. 11 psi of boost/15 degrees of timing and breaking up in the 9's for AFR.

Second pull I got the tune a little closer it did 650ish still same boost/timing. Little cleaner AFR.

Third pull , still working on the tune..... 670rwhp/601 rwtq on 12psi/15-16 degrees of timing and a pretty rich afr of around 10.8 ish.

4th pull got the Afr cleaned up added 2 psi of boost and did 706 rwhp/625 rwtq on only 14 psi/15.5 degrees of timing and around 11.2-11.6 AFR.

I decided that was enough power to try out for the first time out. Overall I am up 130 rwhp and 103 rwtq on 2.5 psi less boost. This thing still has A LOT left in it but like I said I wanna see how it does on this for now.

I have also been driving the car alot to and from work etc.

I really did not think that this stock JUNK would make this much power especially on low boost. All numbers were made on GARBAGE 91 octane pump gas and meth. I will post the dyno chart as soon as I get a chance.

Ran the car last night and learned a few things.

It ran 9.55 @143.5 1.49 60 foot and 116.85 1/8 mph and 6.17 1/8 ET

BUT its blowing through the converter HARD, its on the limiter at 6800 about 300 feet short, hence the low top end mph.

That was on 14psi and pump gas/meth.

I think with a real converter in it and get it to actually 60 foot its got some 30's in it pretty easy.

Street cars RULE!!!!!! Some pics from a few weekends ago when we made a 5.5 hour(each way) road trip and did some 100 footer racing.

Here is the dyno chart, the converter was slipping about 20-25% on these dyno pulls based on the mph and I spun it to 6600 rpm.

Now I can start turning it up! and getting it to actually leave hard.
