Pontiac G8 2008-2009 - HSRK, under drive pulleys

hey does anyone know where i can get these items or any info if the void warranty. how much do they help horse power and is it worth getting them? thanks..

You can get the HSRK from Vectormotorsports. It prevents the ECU from pulling timing and definately makes a differance. I got my UDP from Livernois motorsports. It will add 5-10rwhp and helps the engine rev quicker by reducing rotational mass.

will these things void warranty?

Do they no, but can they. Depends on the failure and the dealership

so if i installed it do you think i would have trouble at the dealership?

I donk they would care about the HSRK at all. They might not like the pulley. Its not difficult to swap them back out before going in for warranty work.

so the hsrk is fine i wouldnt have any problems? would it b hard to install it on a vararam intake and would it throw any codes?

I have a Powerbond UDP on mine and have since about 500 miles with no issues and I doubt I will ever have any issues from it.

The HSRK kit I personally dont mess with, I just adjust my IAT tables and it gives the same effect and didnt cost me a thing.

Hey jacob dont forget to install the flex capasitor!!!

LOL..

Black widow, how do you like your vararam intake. I've been looking at getting one, have you had any issues with it? :usa:

Not BW but I noticed even before my cam the car pulled harder above 50 as compared to another cai

so the vararam is the way to go????
