Kenne Bell install with numbers now as well.

Doesnt matter the IATs. It will ping with 13 degrees and cool IATs. It could be carbon build up. It could be just that thats were its gonna ping at 15 pounds of boost with no meth. No telling. But, with the meth we'll be able to get at least 4 or 5 degrees more, maybe even more than that.

Sorry guys this was not a max effort yet. Meth will go on as well as a more capable fuel system when the forged 347, TPIS Stage III 6.0L heads and a Futral FM8 blower cam. Stand by guys a lot more in this setup for sure but remember this is a stock motor on a stock fuel setup with a BAP.

Well there's something that I don't know then. Doesn't meth just lower the IT's? I would now guess not from what you are telling me. I thought the IT's really affected the amount of timing one could run a great amount along with other things like compression and spark temp fuel octane etc etc?

As for the IATs, the higher the temps, the more timing is pulled. But, this can be tuned. There are several tables that all have to jive to end up with the desired timing without KR. You've got the low octane table (which it runs off in SD) the engine protection table (retard), the boost timing table (retard) burst knock, IAT retard, and I'm sure theres more. You gotta know where to add and where to subtract.
Anyways, on the last run, the IATs where low enough to not be pulling any timing.

From what I understand the big bore 2.8L is meant to be run @ over 20psi to really get her moving and that the 2.2L and 2.4L KB's are actually more "efficient" with the lower boost pressure.
Regardless, thats awesome man! Always cool as **** to see a KB on an LSX

How effective is the KB intercooler? Or any twin screw or roots type blower for that matter it seems the intercooler is way too small for the motor when the intercooler rests underneith the blower. I know compactness and ease of install is the main principle, but intercooler is not a place you want to skimp thats for sure. I would rather have a KB blower minus the intercooler and send the intake charge through a large FMIC if that was an option.

Well the screw heats up the air as it is compressed so the only effective way is to have the intercooler under the blower. Put some pure meth on it with a boost activated switch and call it a day. Meth will lower IAT's tremendously and allow for a lot more timing. Best way to do it unless you wanna run alcohol or nitro-methane.

lol:thats what I don't like about those types of superchargers. I like being able to run a nice lookin FMIC and meth is not needed really. I do like the torque curve of the twin screws and roots type though. I went turbo for reasons like greater efficiency, jetlike sound, more power than any supercharger, not having to worry about a belt, being able to change boost levels with the press of a button inside the cab, and don't forget about the turbo whistle!

Love the KBs man your setup makes me cream my pants. I can not wait until I can get my Maggie!!!!
