60'- 2.308
330- 6.381
1/8- 9.758 @73
1000- 12.64
1/4 - 15.02 @92

i revved it to about 2300 that launch

**blueguy** · 09-09-2010

For every .1 on the 60' you take off...thats an average of .25 in the 1/4. So...if you would have had a good launch...say...a 2.0 60 foot...the nyou would have been close to that 14.5. But...sounds like the car is knocking just a tad. That's a really low trap speed even for stock. My stock car went 95 with the headlight/air filter out.

**xsvtank** · 09-09-2010

how is it knocking its stock pulley?

**matt5112** · 09-09-2010

it happens. i was knocking when n/a with headers on 94 octane

**xsvtank** · 09-09-2010

alright well if i can get a pulley puller im dropin my pulley and my friend (worked for slp 15 yrs) is going to tune it claimes he can tune it for a 3.4 with no knock so we shall see

**blueguy** · 09-09-2010

Ya a 3.4" with no knock and MODS. DO not drop pulley sizes without reading this...and I bet your friend can NOT tune out a 3.5" or a 3.4" on a bone stock car...that's ignorant.

ive read it i know and well see if it knocks ill go back to stock pulley and get headers

**CTKGP09** · 09-09-2010

you should get headers anyway, it will only help you

**matt5112** · 09-09-2010

Your car is going to be a fail on a 3.4 without headers or any exhaust mods...

**CTKGP09** · 09-09-2010

^^^agreed and thats no fun

**xsvtank** · 09-09-2010

ikik i hear it all the time ill see but im doing rockers and headers over the winter anyways lets chill here if i break my **** i break it

**blueguy** · 09-10-2010

Well thats like saying...if I light this match next to a gas pump...might die...but I might die.

That's ignorant dude.

Hey man we are just trying to save you some money.... ALOT of money. Chipping a piston or pistons will cost you proably more than your car is worth. I'd wait to drop pulley sizes until after you do the rockers, headers, and proably should go with a downpipe, u-bend delete ect. But thats my $0.02.

Best, Lenny

**xsvtank** · 09-10-2010

thanks guys and ^^^ i already cut out u bend and res (not saying its enough)

**blueguy** · 09-10-2010

Resonator does nothing to help exhaust flow...all it does is make your exhaust sound horrible. You still have 2 out of the 3 restrictive parts of the exhaust...the downpipe and the front manifold. Plus...if your car is knocking...its just gonna go slower in the 1/4 anyways than stock.
