Most Reliable Centrifugal SC?

The first one was innovative sc, second ful bown turbo, third vortech.
For hard core track use I have a talon AWD since 1992 and still Runing strong. Of course I have to repair or replace the tranny 4 times, 1 transfer a lot of clutch and 2 engines (that's the car that I learn mechanic with).
Also have a 2 Toyotas, the first one in a old school 22re with all (built engine, stand alone, full suspension and supportive mods) but that one is for off-road use and I really mean off-road. The second toyota I just buy it, is a supra 2jz, I did pay a lot but the car is full built 1300whp that's the 1/2 mile beast.

About track time/miles... Hmmm I start racing at 7 and still compete at 41, that include motocross, cross country, go karts, cars, mountain bikes, road bike and triathlon.
With that been said I could tell you that I do have a personal machine shop and I'm a freak of suspension mods, sadly the frs didn't need much help in that department, but you know that. Only as the rubber get more traction you star to fell the need for some bars.

Anyway I don't do this for a living its just a hobbi.
That's my experience

Gd that is a cool story.

There you can see the needed modification to the air box screw. The pic with the bike is only to show we're I get the 100 octane. Last the 22re is NA, high Cr full modify that is the ride to go racing.

So yea pretty cool I think.

As far as kit issues, the only failure I've heard of is people not clamping down piping and having boost leaks.

Read the threads and look for what problems people report.

Key word here...Rotrex. It doesnt matter which unit you are running in centrifugal, they all use a Rotrex manufactured unit. The difference is mainly preference in piping, pulleys, install, intercooler, overall look etc. The point of failure that is most costly is the actual blower though. and KW is the only company that has had significant non-blower issues.

HKS is the only company that stopped using Rotrex (they actually manufactured the units under license) and went ahead and produced their own unit with improvements.
The shaft for the compressor is significantly thicker than the one usually used in the Rotrex, plus they disengage the traction drive at low revs to reduce parasitic losses with a spring- loaded roller.

The only down side with HKS is you have to notch the metal in the bumper for the intercooler pipe and the stuff comes from Japan with minimal representation in North America. However I believe I helped the US distributor blaze a trail if anyone ever destroys a supercharger unit and needs to buy it standalone. There was, and hopefully they have resolved gross inefficiency how that went.

Agreed, I went with the JRSC due to not having to cut anything and the integration of the Engine Oil Cooler and not having to have a second mounting bracket for the Oil Cooler.

I don't believe everything I read, but I do remember reading about failures with the HKS compressors as well, enough to make me think twice about them. In the end, I think they both can fail and it boils down to how the companies back their products. Also I imagine a good number of failures tie back to poor installation - i.e. incorrect belt tension, poor priming, etc.

There are several failures reported on V2 units apparently purchased grey market in Russia. My unit failed due to my error. Not aware of any others.

HKS has provided thousands of similar units for Yamaha jet skis with no known problems documented.

So what answer did we come up with?

Based on my reading through the thread, I will be putting my money on JRSC. Thank you @CSG Mike!

TBH I'm running the JRSC c38 and other supporting mods and I'm loving in. Yeah the Eforce would have been nice to have for the low end TQ/power but I like to keep my reva high and fly.

There is HKS SC oil for COLD area
http://www.hks-power.co.jp/product_search/product/727
part no. is 12002-AK030 ( for under -20'C )

I think Russian guys didn't know about that. (almost every HKS SC unit in russia failed)

there are Tons of HKS SCed cars in Japan. but I can't find any report about early unit failure in japanese forum or blog.
