Yeah, i reckon ppl should post there secrets, to help other fellow competitors out.
One of the problems with my car is its weight 
But... im not too keen to start ripping crap off a HSV.
But we shall see....
ATM, my plans to go fast are mainly diff and heads/cam

my plans are new engine, 10-12 psi of boost, bigger exhaust, spool with 3.45s, maybe some weight reduction, and possible head work.
if people want to be posted up in the first post, just reply with your cars details in a similar format and it will be updated

Im gonna give it a damn good go, although my chances are pretty low. Would be nice for the first car to get under 5s to be a wagon 
Planned engine work over the next 3 months...(buick V6)
Port and polished heads (flow tested)
Forged pistons + racing piston rings
Larger cam + roller rockers/springs etc
larger throttle body
vortec supercharger + FMIC @ (hopefully) 12-14psi
custom ECU/upgraded injectors/engine oil cooler
LSD (not sure on gearing yet)
What do you guys think? under 5 seconds is probably a bit hard with a V6/Wagon combination, but im going to give it my best.

have updated for you feistl. i assume your engine is currently stock? im not sure how the vortechs go in terms of acceleration, might be a little slow off the line, but should still see a decent time if you get it all done right.

the problem with the manual trans and buick V6 with 3.45 gears is that you run out of puff in 2nd gear before you make 60mph which means you need to get 3rd gear which costs you a bit of time without power going to the rear wheels. you really need to rev it out over 5500rpm and the buick just doesn't make any power here unless it's cammed with decent heads on it. the autos don't ahve this issue

:P. Wasnt expecting to be put on the list, now i really have to get my ass into gear :P.
Engine itself is stock, rest of the car has been worked. Ive been trying to get the car ready to handle the power (Eg brakes, suspension, wheels, clutch, exhaust, intake, cooling etc). Now that the car can handle it, i can start prepping the engine for a supercharger.
Oh, and best time btw is 7.9s

well, because atm i only know my cars weight and rwhp i used a bunch of different estimators/calculators - a 1/4 mile one first to convert with another estimator into 1/8 mile specs then putting the et and mph into the 0-60mph estimator it comes back saying my car should do 0-60mph in 4.18 secs apparently....ill have to find a g-tech and try one night
