Stick or auto?

 

Your brother is most likely going to be dead even or even edge you out with the mods he has done. I would start off with headers, a tune, and some sticky tires, that should do the trick.

 

You win from a roll, lose from a stop. The SC3800 has no top end.

 

Its a auto
to 93 Phoenix its actually the other way around with the supercharger he beats me off the roll Lt1's arent known for ther top end its weak and i get him from a dead stop but thats with stock 2.73's before his tune and 1.84RR's

 

Well with an auto going to 3.73s put in a 2400-2800 good top name brand torque converter with a good set of sticky tires and he'll never see anything but taillights from a dig or from a roll.

 

Thats the way it should be thought maybe an eletric h2o pump you guys know anything as far as gains and also disadvantges??

 

Don't go thru the trouble at this point. Do as AL SS590 M6 stated. 3.73s a "GOOD" 2800 stall, and a set of drag radials will make a huge difference with your car. Throw in a tune and a cut-out and you will not only kick his ***, you'll have a big grin on your face for quite a while.
Don't forget a trans cooler and maybe a shift kit to help firm up the shifts if you go with a decent converter. And remember, no restalled stock converters are exceptable, ever!

 

It will give you about a 10 hp gain, plenty of other mods to do first. You may also want to consider doing some weight reduction, its free!

 

True That i love free mods!

 

Just be sure you can out launch him.....and tell him to buy a Random Technology downpipe!

 

Yeah, I have a R/T downpipe he can buy.

 

I believe it is a R/T down pipe.
to everyone else thanks for the advice i'll let everyone know the results in May after nationals
