wew 9 psi and 390-415 rwhp is enough to handle a stock block on premium fuel. I can't imagine trying to squeeze more boost out of that on the stock compression without race fuel.

not yet.......still trying to get the tune right for my #9 pulley.....I think that Ken fixed it now though!!!el_kid_1 said:
Right on, I plan on using it only for the track with 100 octane gas. Although I spoke with Ken and he said that it should be OK for me to up the boost by 1 psi since 93 octane is readily available at every pump station in Puerto Rico.kirkyg said:
With the KB supercharger, every psi of boost requires ~1.5 octane over 91 octane. Therefore, 93-91=2 octane....2 octane/1.5 octane per psi = 1.3 psi more. 9 psi + 1.3 psi = 10.3 psi or 10 psi. On our kits, every psi equates to 17-20 rwhp. Anyways, I would not go anything beyond that for street use. As I said, I only intent to use it at the track and with 100 octane gas for an assurance. As far as I know, our stock blocks can handle up to 450 rwhp. That's what KB suggested...not going over 450 rwhp.

Sounds like you've researched your stuff. Just be prepared for the cash to build a new block when your pushing the limits of your current one

I have the chip, but haven't put it in. I am in the Navy, stationed in Maine, and the car is in my parents garage in NJ. I need to get back down there to install the chip and tow the beast back up here. Should be all good though.2002BLGT said:
