92 is the flavor we get in the PNW. There are a few e85 places but it seems like a pain so not going to mess with corn fuel. We only have a couple stations around here. They need to make a Blackberry or Christmas Tree fuel. That's what grows in Oregon.

Cool I'm very anxious to hear on the drive ability and feel of this and JRs kit for sure. Doing lots of research lately and this particular blower sounds to be very reliable on other platforms.

Can we have a photo of the intake tube that goes in the front bumper please?

[digital_assassin]

Here we go! Entering last week of the month. Time to ship those kits and take my money.

here you go:


the tube is rotomolded from thermal-insulating cross-linked polyethylene. the tube is 3-1/2" diameter. we used extensive computational fluid dynamics (CFD) to optimize the shape where the tubing passes through the rectangular opening in the radiator support to eliminate any flow loss.

people try to discount the importance of a cold air intake on a forced induction system, but the bottom line is 10-20*F cooler at the intake is still 10-20 degrees cooler after the intercooler....the net effect is this....the intake air temps on the KW kit are only about 10*c (18*F) over ambient...very little heat is added to the air when it is compressed because the rotrex stays very efficient, which makes minimizing intake air temps at the filter important

anyways...other players might dismiss their oversights as not important....but every degree counts

i would love to see a back to back test between all the supercharged kits because IMHO i feel we covered ALL the bases better.

There will be a very good chance of this happening as soon as the kit is in my hands . In the next two weeks Bob @Drift-Office will be tuning my KW kit, a JR kit, and an Intercooled Innovate kit. Missing the Vortech kit and HKS kits but close to all of them being done on the same dyno and at the same time of year so temps will be close.

Thanks. I can't wait to have my kit!!!

my intake is in the same place as this kit's, and my intercooler setup is similar as well. i see intake air temps rarely more than 10f above ambient (only when sitting still, never moving) and usually within 5f. last night on the highway i logged intake temps 3f *lower* than ambient. so, they're doing it right .

The Innovate with the Intercooled option doesn't look like it's going to make my deadline. I have don a Vortech and HKS kit w 6PSI limiter too, so we can get something going for all of those...

I'm interested in seeing the diffs between the KW and JR SC kits, myself.

If we were closer I'd loan you my car for the comparo.

I think it is a 12 hr drive from SF bay area....

A friend of mine just drove up and back this past weekend. Thanks though!

Yep, really lucky to be able to do both at my facility at the same time.

Cheers!
