adamshowtime, hello.
First time to the forum, I'm the owner of the blue skyline with twin superchargers w/ intercooler, these pictures were submitted to HPI website. (Previously was a single supercharger on the supra) Please note that the supercharger is a research mark-up for R/C product development. the SC that you saw was hand-crafted. meaning less precision and tolerance on the casing, tubine and shaft. I have tested them up to 20,000 rpm. the SC itself does not boost pressure but increase a lot of CFM. the intercooler was spreaded with CO2 to lower the intake temp. the A/F ratio need to adjust to a slightly richer setting....

Bottom line: the Supercharger does help but not a lot on a 2-stroke engine. I have seen a big improvement at the top end (where CFM is at its highest level) but at low end, it is just almost inpossible to tune without pressure regulator.

Keep your eyes out on the [link=http://www.hpiracing.com]hpiracing.com[/link] gallery. I will be posting new pictures for my RUF porsche with rear mounted intercooler and lancer EVO V. Both supercharged and intercooled. I'm also working a chassis dyno bench. it will read Hp, engine speed and wheel speed.

Any one interested in my development, please email me [email protected]

PS. the supercharger is a registered design.
