Darbs I recently came across a rear mounted turbo tundra. He was doing his shakedown runs and his A/F gauge read a stout 11.2 at WOT. He was running around 4 psi. Let me find the thread and video. He was untuned as well.

Just an FYI, I run 7psi at 11.2-11.7 afr on my is350. We have an is250 that's been running 8psi for well over 15,000miles without a single hiccup as well. Apples to oranges but I know the F is capable!

Yes, it is. Unfortunately, it will not be making its debut any time soon as Lotus have axed the Esprit it was to power. Details here.

As it turns out, the quote from the lead technical guy above is inaccurate regarding the Lexus engine. He was actually describing the in-house Lotus engine. I was wondering how they'd managed to set redline at 9400 rpm given the long stroke of the 2UR-GSE. They didn't.

Most performance mods need a watch and timed course to demonstrate actual improvement. Few deliver the advertised claims. Many are actually worse than stock. The best performance mods are made to the driver.

Emotional arguments - They're not just for chicks anymore.

Add 50/50 water meth injection and get that AFR in the low 12's!

Darbs here is that build thread and video about that tundra with no tune. I may have misspoke about the A/F, but you can see it for yourself.

AFRs look tapered from low-high RPM, 11's to 10's. Pretty safe.

Hmmm. I do remember reading he said he had no tune. Maybe he upgraded.

Officially bought the Greddy blower and custom Greddy IM! I'll start a thread as soon as I have it in my possession. Debating picking up the Greddy catback but it just looks like straight piping and ends with titanium spectrum elite mufflers and tips. Not really my style. Specs state The system is made up of 70mm full dual piping to 60mm quad piping finishing with four 115mm tips.

^^^^I'm Confused Aren't you the fella putting an ISF engine and transmission into an '06 blown IS350? And, who doesn't want to use the ISF hood because of the "Beluga Whale look?"

Yes, thats me. Those werent my words though; I only agreed with another poster who made that comment. Its nice to have choices in life....If I decide not to use the Greddy setup I'll be using another Rotrex cent. unit to accomplish my goal(s) for the 2urgse.

If you decide not to use the Greddy setup I will take it off your hands. I would have a second IS-F motor on stand by in case mine goes kaboom.
