The power steering system runs hot anyway... but now that you have added so much horsepower you are driving it that much faster. It also gets dirty fast, even boiling it aty track events. My own Infiniti dealer sees this a lot as well.
I also recommended a spare belt... not that it has any special propensity towards just breaking, but it is now doing a double duty that it was not designed for (most factory supercharged systems will use a separate belt or at least a wider and stronger one. In the G, there is not enough room in front of the engine for anything like that. This is not a Stillen issue, it's simply the lack of available room). And also carry one because it's an odd part # that is not regularly stocked by most auto parts places. Keep an eye on it... any signs of wear at all and it should be replaced. I replace mine regularly after the original got old and just snapped on me. Changing it is murder...

 

Thanx man, An your talking the drive belt correct. I will have the dealer look at my PS fluid next oil change.

Yes, the single belt that powers all the accessories as well as the supercharger. It's a Dayco "Poly Rib" 5071045. I also carry a diagram showing how the belt goes on the pulleys, it may be self-apparent to some but it is complex.

I have a set of images I'll put in the DIY section if I ever have any spare time. I photographed the entire thing last time I did it. Not a big deal to do by hand, but there is a special wrench I bought which makes all the difference.

 

Nice thanx man.

 

Food for thought: You can see from these images why a forced-induction G needs a replacement exhaust system.

This was my stock G37S exhaust system y-pipe. It's TINY and very restrictive.


Here's one of the two inlet sides. They are especially small, only 43mm or just over 1 5/8".


And here's the single outlet, 60mm inside diameter, just under 2.5". I'm surprised that Nissan engineers didn't at least use an oval outlet.


There's a reason why it's small - exhaust flow velocity = low end torque. But this clearly won't work for a F/I G37S that may be capable of 500 horsepower at the flywheel.

My supercharged G uses an ARK GRIP Burnt Tip exhaust to replace the stock system, providing for true dual exhaust and far less back-pressure. It's a bolt on to the stock converters, and replaced everything behind that. It's designed very well... fits very well... but it's not for everybody. It's outright guttural at idle... way too loud for many neighborhoods. From the inside of the car, it's also loud at idle. At highway cruise, it's easily tolerable, not interfering in normal conversation.

On a naturally-aspirated G, IMHO, you'd loose too much torque with this and it would sound lousy. It's just too big. But clearly the stock system is too small for a forced induction car.

 

I'm stock exhaust and I am FI and make 500hp to the flywheel.

 

anyone know if the Hotchkis Sway bars fit over the stillen supercharger kit?

 

You mean under. None of the components are anywhere near the supercharger, which is mounted up high.

 

Yes they'll fit, i have them both installed.

 

My Hotchiks, are on the way ,"Should be here today", An I have a front tower bar"Memeber from here". I will be installing them this Saturday.

 

I was wondering if I added a exhaust system (cat back) would I see any real gains. Also this was on a Mustang dyno.

 

Which brace did you get? And will it indeed clear the intake tubes on the left?

 

I hope you FI.. LOL Or super inflated, HAHAH, you a cat back you shoud see another 10-15 WHP, see my sig,, 7spd auto and AWD Mustang dyno also.

 

NO!! Didnt clear.. LOL Sold it the day after I got it.. . I dont think there is one there is ZERO room over there.. LOL
