Default what to expect from Headers and underdrive pulley?

I already have the headers/ory thats gonna feed the open borla exhaust that is already on the car.

I wanna get an underdrive pulley cause i hate the slow rev of the motor so im thinking the underdrive fix that somewhat.


so what should i expect from those mods?

yeah I'll go ahead and get a dyno tune at Tick Performance while im at it.

I know the heavy *** flywheel plays a part in it too.

Ok then, I'll start an other thread and ask what it could be....

Changing the pulley for 3hp is hardly worth it,unless your never going to mod it further.

If you plan on doing a H/C swap in the future do the pulley then.

25hp off the headers tune will help the most, maybe 5-10 off the pully

You can get the Powerbond combo from SDPC which has the pulley, perm bolt and 2 belts for $220. Here is a link to it:

Listen to these guys, youll save yourself time and money.

Stage the mods.

No sense in putting on the UD pulley if you have to take it back off to install a cam in a few months. Dont risk damaging the crank threads either, buy the tool to put the pulley on from one of the vendors or from the classified ads.

You will see, as mentioned, the headers will give you the most power especially with a tune.


+1 on the SLP 25% pulley
