They will all give you about 6hp Get the trick flow ones for your year.

 

Steeda FTMFW

 

MARCH. best that i found.

 

Just get the summit ones they are exactly the same as the trickflow ones but $10 cheaper.

these all net about 6 hp at wheels so about 12-15 at flywheel correct?

 

i would say its more than just 6RWHP. i would say its probably above 10, you feel a difference, and the engine also spins up more freely.

honestly, i think its one of the best single mods you can do.

 

I have steeda and noticed a different, so I say steeda

 

steeda, slp, motoblue are not a piggy back type. i did not feel anything when i did mine.

 

I think a tune would be a better way to spend your money, JMHO

 

i agree with war party and also if you plan on boosting in the future
i would not invest the money.
i would get a tune before the underdrives.
just my .02 cents.

 

Under drives are only like 90 bucks.

But if you dont have gears get those. I have pulleys and didnt notice much but a little. I have march. Andlike someone mentioned before Summit doesnt sell march pulleys for 99-04's Yet

 

Just make sure the crank pulley has the damper on it (like sweet2kstang said) and DON'T get a piggyback one. The previous owner of my car used some generic set and either was a hack or paid a hack but from the minute I drove off the lot my car started misfiring. I took it back to the dealer 8 times before they figured it was the pulley slipping. They overtorqued it and ended up snapping the bolt in the crank, then told me it was my problem and I needed a motor. Almost 8k later I am back on the road.

 

i have the steedas. engine revved faster but it's not a big gain in power. 6hp at the most to the wheels
