Waiting for a response from KW on the kit with the 70mm upper pulley vs the standard 75mm upper pulley(standard in their mass distributed kit) before I submit my order.

Trying to compare how much boost it produces at 7200rpm vs the 75mm pulley designed to spin the rotrex to 7800rpm on their base maps. To me it's sounding like the 70mm is the route to go, I do not want to rev anywhere close to 7800. I have a long history with Subaru oil pumps in regards to cavitation.

Why not go with the C38, and use a larger pulley? This will give you future room to upgrade to more power when you eventually want it, without over spinning the C30 SC.

Received my new belt cover, need to install it. I've been driving with snow/ice tires here and haven't had any issues on the ice. I've had to keep it around 2k rpm to keep the rear in check, though.

I love this kit, the power band is great. It is all you need from 2.5k to about 4k rpms. Then if you really want to have fun, you have that last 3.5k!

who here is running the c38 compressor? any pic of that setup?

Looking forward to seeing how this kit performs on our XLR8 BRZ. We've had great experience with the Kraftwerks kits with the Civic, S2000 and Miata platform so the FT86 platform should perform well too. Thanks for the feedback.

Not overly concerned. Should be able to make a little more then 350whp out the c30. Won't really need/want more. I have a 550whp+ sub 2500lb rwd coupe already.

Also guys, just for reference the 70mm pulley produces approx. 12.5psi vs 9.5ish stock 75mm pulley.

OmarGC · 01-23-2014, 07:41 PM

Of course your boost may vary due to exhaust restrictions/rpm range.

Are any of these recent Kraftwerks designs that use the cogged belt?

Are you trying to instill doubt in a cogged belt? I'm pretty sure you know the answer to your question.

I'm more interested in knowing if they've finished development on their S2000 kit. Calm down.

Finished the install last night! Thanks to @digital_assassin for the helpful tips, @FT-86 SpeedFactory for the great deal and fast shipping, @KraftWerks for designing the kit, and @DeliciousTuning for the basemap!

Here's a pic from last night. Still need to install the bumper but I'm debating whether or not to remove the grill and expose the intercooler for that "bling" factor. I still haven't really ran it hard since it decided to snow last night but I took an easy ride around base and everything seems fine so far. Also didn't realize how loud the whine is but I like it! Lol

digital_assassin · 01-26-2014, 01:53 PM

The whine is going to be tamed once you get your new pulleys. Night and day difference. Whine is still present when driven hard though

grostoine · 01-26-2014, 02:03 PM

Your new pulleys? You a re talking about the 70 pulley ?Or we are suppoosed to get new pulley to quiet down the system a bit?

Idler pulleys with teeth
