Define "full exhaust system".

If you've deleted cats, then you'll need a custom tune. If you still have the stock header and overpipe, then you're good with the CARB tune.

Catbacks don't add power, no matter what the manufacturer/vendor claims. You'll see why FI is the way to go once you get your kit. More hp/dollar

Catted UEL headers, Motiv front pipe and over pipe, and greddy exhaust

My apologies if I missed this, I've read so much over the past month my head is spinning. Are there any high boost pulleys in the works for the JRSC?

What is the stock pulley's size and max boost?

You'll probably need a custom tune.

Boost depends on where you live and how the conditions are. Stock pulley is 110mm.

I can't comment on the rest

Where would i get the tune done? Like i said all new to this

If you are having it tuned locally...

California - Delicious Tuning
NW USA - Probably Drift Office
NE USA - Moto East
SE USA - Jamesm at HRI Tuning
Central USA - ???

E tunes - Jamesm, Delicious Tuning or Moto East. Jamesm would be my top pick overall for either types of tuning. Apparently, he's an absolute baller tuning this car.

NDA for any possible future products and as for a maximum... Legal liability. While his engine might have a max boost of 25psi, yours might only be 20 psi. So if you try to go for 25 and how your motor, you might try and sue him over it.

read between the lines guys :p

Yes. Yes I am

I just like bugging you about it. Constantly.

It would be nice if JR comes out with an "upgrade kit" that includes everything (pulley, new track tested tune, etc.). I'd gladly fork over more money.

Wishful thinking. I know

patience!

Would you like to discuss the horsepower gained from the evacuated crankcase (on a motor with a third of the piston underside surface area of that rat motor) and how that compares with the horsepower lost from the intake system being restrictive enough to allow a turbocharger to draw the kind of vacuum it would require to actually evacuate the crankcase? Because we could do that...

If you know how those pumps work, yes.


You're still missing the point that PCV is not simply about emissions. The percentage change is the obvious point in the HP figures or does a smaller motor magically turn into something different that defies physics?


Also, one doesn't need a major restriction to draw a vacuum.


It's not hard to add catch cans into this setup:

I do know how they work. I know why you gain power with them, and I know the PCV system will never be able to draw any real vacuum in the crankcase, which makes your comparing the two ridiculous.

I'm not the one missing the point here. I completely understand your point and I am rejecting it as ridiculous. Big difference.

No shit there would be a percentage change. I'm not asking a system to defy physics, that's you. You're the one claiming you can gain power by evacuating a crankcase to nowhere near the level that a vacuum pump does...
You can't evacuate a crankcase with the turbocharger's intake pipe without that intake pipe being under a deep vacuum. When that intake pipe is under a deep vacuum your compressor is working at a high pressure ratio and producing a lot of heat. Not to mention that when you pull a vacuum on a chamber that's full of oil vapor you pull that oil vapor out and coat the inside of all your intercooler piping and the intercooler itself.

I invite you to prove me wrong. Hell, I hope I am wrong. Rig up a vacuum gauge to that crankcase in your supra and make a video. Let's see the pcv system in action pulling a partial vacuum on the crankcase.

Also, one doesn't need a major restriction to draw a vacuum.

I work with vacuum systems every day. You're wrong. Did you bother to read that article you quoted? It said they had pulled 6" of vacuum on their engine with that pump. How are you going to do that with a PCV system on a turbo engine without a restriction at the intake that soaks up power by moving you into a higher PR on the compressor? Remember you need to flow all that crankcase pressure through your small PCV lines and catch can. Drawing a minor partial vacuum in your turbo inlet pipe isn't going to cut it.

It's not hard to add catch cans into this setup

Which brings us right back around to my statement that no oil separator is 100% efficient. I work with the most efficient oil separators in existence at my job, and I get to deal with the problems caused by the less than 1% of oil being left in the discharge of the oil separator quite often.
