its a great blower if it suits your driving style....u have to think about how you drive and what you want out of your car...i love top end and having the car pull harder and harder as the rpms go up and never having the power drop off thats y i went with a centri
either one will run with an ls1...but the centri will pull an ls1 that much harder up top...a kb will blast it out of the hole though...so like i said, it depends on ur driving style and what most of your racing consists of...going from digs or on the highway
Make sure you beef up the tranny as well. And maybe look into a high stall converter. With the stall and the KB you will be leaving the ls1 guys at the light. That is of course until you run across one that is built.
10psi on a stock 02 gt and a 2.1L KB = death.....i know...buddy just blew his engine. great blowers....but recommend forged internals with that poweradder...imo. by the way read KBs site because once you set that blower to 14psi it loses 3psi after a certain blower rpm...the blower is most efficient at aproximately 10psi...been doing their research on the 2.1L vs the 2.6L just a thought...do alot of research.
the above is the 2.1L blower. direct bolt on with all parts needed (from kenne bell). the 2.6L is a tuner kit and requires that you build the kit and get a custom tune. just an FYI for all who dont read the whole thread.
I have only seen one in person. It was a complety stock KB GT. stock wheels and tires even and he was whoopin up on a vette. TA wasnt even any where fair race. Dont know the boost he was running, it most have been under 10, just a guess tho.
