meth whp?
anybody got any idea what whp and wtq numbers we can expect from these meth systems? something like the bms one what you think you can expect? we know the whole raises octane and cools temps but what power can we get out of it?

i'm no expert, but my understanding is that the meth ALONE will not net huge gains. it would be similar to putting race gas in the car as far as hp gains. however, it does make the car much more consistent due to its cooling properties and ability to drastically reduce heat soak. but the meth allows you to go more aggresive in the tuning department in the form of raised boost and advanced ignition timing, and that is where the BIG gains are found.

I expected a much bigger gain. Except you race, do you really feel a noticeable difference ? 15 -30whp on a tuned, already pretty strong car ? I'll carry on with european premium gas .

It think you will especially see it on extended, on multiple pulls where high IATs would normally kill your performance. I would say meth will have a bigger impact than a bigger intercooler alone would have. For no more cost than an intercooler.

I had 7 runs in a row on a dyno at 16.5 psi and the difference in power was almost non-existent.
