what 70% of meth is added? mixed with water???
I use a 70/30 meth/water mix. The kit looks pretty invisible. The Procede is hidden in the DME compartment/box. The meth pump is mounted on a bracket under the hood. A custom-fit harness connects the procede to the meth hardware. I'm not don't with the custom brackets yet so I'd rather not post up pics of prototype stuff. But once they are all laser cut and powder-coated, i'll post up complete kit pictures. The whole kit is easy to install. Expect to spend about 1hr. Don't have to get the car on a lift or run any lines under the car as it re-uses the factory windshield water bottle. You don't have to take off the bumper either. The whole install is done under the hood. Easy to remove as well if you have any warranty work.

Yes, it picked up approx 30whp with no active changes to tuning. The DME simply ran it's ignition timing targets and the engine ran a cooler, denser air charge. For example, without meth, IATs climbed from 35degC to 55degC. WITH METH, they DROPPED from 35degC to 15degC. Some pretty big passive gains right there.

I'd be very interested in running this set-up on a non-intercooled set-up since they seem to be so popular. I'd imagine bigger relative gains that what we saw today since the temp drop would be so much more significant. Plus, we could undoubtedly run a higher boost pulley since the meth would perform better than any intercooler upgrade.
