Jackson Racing Supercharger Owners Thread

But if it's going to be run hard on the dyno right after being installed, wouldn't that put the supercharger in harm's way without doing the break in period?
How long is the break in period supposed to be?
Would my car be safe to run around town just to get the supercharger up and running a bit before the dyno tune?
Any advice will help! Thanks!

I recommend getting a base map from your tuner, which will allow you to drive around, conservatively, and safely, to break in the supercharger and drive to the dyno.

Alternatively, CSG can provide you with a complete tune and a JRSC, so you don't even need to bother with going to a dyno.

That makes a lot of sense thanks!

Thanks for the advice CSG!

Quoting this message is completely broken... sorry

On #2 Is the bypass valve loud.

yes, it's loud enough. You can hear it very clearly on clutch-in, let off throttle to shift up.

I could hear it when I was light on throttle (until it failed) but I can now hear the replacement very well when I'm light on throttle and am high-ish rpm.

However, if there's anything that project cars taught me it's that stability and traction control are your best friends and a stock FRS is plenty fast.

I’m one of “that guy” ‘s! I also had/have ace type A 350 header/over pipe and full exhaust. I had no oil related failures. My #2 rod just snapped. Not one bearing in my engine was spun. I was on a c30 with standard pulley and e85. I always thought I’d get knocking and then rebuild the engine. I never dreamed my snapped rod would turn into a weed-eater and rip a hole in the top of the engine with no audible warning signs! I could literally stick my hand in the engine and touch the crank and remains of the #2 rod. My new “built” engine arrives tomorrow. I have been waiting on it since February. I can’t wait to drive my car again. It blew the Tuesday after thanksgiving last year. I couldn’t deal with it until February as I was being trained to fly a new aircraft, and didn’t have a spare moment. ! If you can’t afford to do a built engine, then I wouldn’t do both e85 and a supercharger. If you can’t wait the best part of a year to have someone build you a strong engine, then I wouldn’t do both! I truly feel that it will only end in tears. By the way I was stabilized at 40mph in heavy rain when it blew. I wasn’t pushing it at all. Very gently accelerated to speed then stabilized, then kaboom! Choose wisely!

I agree, you need a built motor with the added power. After two years of many track days on the stock JRSC setup on premium gas, this year I upgraded to the high boost pulley and supporting mods (injectors, etc) on 100 octane race gas (E85 is not feasible here) at 320WHP. The engine popped (also connecting rod) after two track days. Earlier in the year, I lost the original engine on a 92 octane tune, also due to broken rod. After loosing two engines, I'm going back to the stock pulley setup.

So, yeah, built engine is the way to go. I spent my extra cash on two used engines (which are not easy to find BTW; not good ones at least).

It's nice that you tested it and it works for you, but, it doesn't work consistently if some of have had to change to metal valves because the plastic valve melts. Mine lasted about 20 track days.

Sleepless,

For your engine to expire at that power level and with such quickness, I would say there was a tuning issue. We did many racing events at high power levels on the same, stock engine... No issues. Ran hard in the heat of summer, in a draft. Tuning is a very important component here.

To clarify, I am not saying this engine can make 500hp on the stock engine and survive. I am not a 90's Import magazine. But the FA20 can take what we prescribe for the stock engine when applied/tuned correctly.

Two tunes from two highly respected tuners on two different octane levels...

Might be a dumb question, but has anyone swapped out the intercooler on their jrsc? Was looking into getting the mishimoto intercooler and wanted to know if anyone had already done it or if it woukd even work.

Bypass valve. Couple posts back (last month?) You could use this with the red spring.

Intercooler, my shop is installing an hks intercooler so I'm assuming it works lol. I think many use the jrsc is because it simply works.

Why would you downgrade?

Would i be a downgrade? I was always told the bigger the better when it comes to intercoolers

You think this atmospheric bov would work?

Its made for the same car the other diverter valves were made for, but im not sure how atmospheric vs recirculated will affect it.
