wow mine is still clear, how did yours get so dirty so quickly??

markforrester99

The oil is 3 years old and done about 7000 miles. I expected it to be dirty to be honest. Any dirt from assembly of the charger will have gone into the oil over time. Hopefully from now on it will stay relatively clean.

About the same as mine and a dozen track days.
Think i may check mine a bit more carefully but I'm sure its crystal clear still

Has anyone looked much into HKS GT2 supercharger kit? trying to find as much info as possible on it as I'm thinking of going down that route but not really digging much up except for HKS actual website.

It looks to be more reliable then the kW kit for sure

Wonder if it can be fitted to existing GT brackets without buying whole new kit.

markforrester99

The only info i found said that it used a billet compressor wheel. Nothing about any other changes. Still appears to have the same 110,000rpm limit

I have the GT2 kit. The performance specs are identical to the original. The only difference is they beefed up the internals so in theory it should be more reliable. I also replaced the standard diverter valve with a Tial BOV from day 1.

I did read about the beefed up internals and that the chargers max rpm is still 110,000rpm so yeah it should be more reliable but the urge to fit a 12psi pulley as opposed to 10 psi is that much more tempting.

I upgraded to the smaller 110 mm pulley and lowered the red line to 8400 rpm right off the bat as well. At 8400 rpm the blower hits 110,000 rpm with the 110mm pulley. The standard pulley was only producing 8 psi for me because I am at 1050 meters above sea level. The 110mm pulley was able to produce 10 psi.
