^ LOL at the last post.
I dont think the supercharger made it to production and the exhaust has been discontinued for quite some time. There was someone talking awhile back about Greddy making another exhaust just not full Titanium. I wonder what happened with that? I rather wait to see whe PPE has up their sleeves.

Back from the dead - Does anyone know anything about the Greddy mp92 supercharger pictured above? I know it was on the 0-60 magazine IS-F but what was its original planned usage (aside from SEMA)? I can only find pics of their car idling and nothing around expectations, pass/fail, etc. Just curious what power this was hoped to put out or really ANY information around it.

Yeah, got that. Any info on what it was supposed to accomplish in terms of PSI, etc?
Yes, we all know that as well...don't think it will ever be cracked in the states.
I don't understand why all 2urgse owners are afraid to let the amazing ECU tune the car up to 5-7psi though? I've been boosted on my IS350 making 372whp at 7psi with the stock ecu handling everything perfectly. I've done countless datalogs, dynos, etc. Without derailing my question I just don't get why people don't think the stock ISF ecu can run the car on 5lbs of boost.
With that said I would be looking to run the mp92 on the stock ecu at 5lbs to see if it can be done. Yes, I have the opportunity to purchase the blower and custom manifold.....

I think this looks a whole lot more interesting. Unfortunately, they've removed the direct injection...maybe that's how they can tune it with a conventional ECM.

Lotus Chief Technical Officer, Wolf Zimmermann, says this engine can reach up to 630 HP at 9.400 rpm and 424 lb-ft of torque Between 5.500 and 6.000 rpm.

Details are foggy at best but I see one giant injector just past the throttle body. Its no wonder they couldn't "tune" it if they were dumping additional fuel with reckless abandon. I would think the stock fuel system is capable of 5psi without additional fueling...I'd actually be willing to bet after all the toying on my IS350 I've done comparatively.

Absolutely! But I've got the greddy mp92 with custom manifold a click away with paypal. Details are foggy at best but I see one giant injector just past the throttle body.

It has always made me wonder what Lexus did to slightly detune the 2UR.

That's going to be a serious project...post up if you get it, I know we'd all be curious to see what it will do.
