@ GT3nut, intressing to read your posts. It seems you guys in USA is keen on datalogging, great for you guys its so many of you got GT4/GT3 and logging.
Anyway, just wanted to ask, how is GT4 engine handle the pressure coming from hosier? Sorry, it might be in this thread but not read all thread.

All seemed to be just fine.

I've got about 50 laps on COTA, and 50 or so at TWS on R7s now, and no issues. It's going to make a lot of miles before we really know.
I don't think we're going to have any trouble..is my arm chair prediction. The CS has the exact same motor, and the teams are running Slicks on it and cup suspension - so much higher g-forces that the street car would do on R7s. All they did was overfill the oil. Porsche said they put over 10K hard track miles on the CS mule while under development.
I suspect we're going to see more trouble with the MA1 GT3R given how things are going with the GT3 engine right now. I hope they have that sorted, but I guess we will see.

I talked to an engineer at the Pirelli Trophy series - he said they are virtually identical. They run higher octane (safer for motor and extreme use) and 100 cell cats (longevity). The dealer can service the motor apparently. They put an extra quart in it, and ECU programing is changed to not throw a warning about it.

It's a good engine IMO and is detuned a bit for longevity and more usable midrange torque.

My logic is not to get any better performance (which you won't), but simply to provide it a small degree of extra protection, or small increased margin of error, as the added octane gives you bit better knock protection, especially on hotter days, or in case you might get a tank of "bad" gas, or a tank that is at the lower octane spec limit.
Always wondered if this logic is solid, or just making me feel better...

Mine is tuned for 93 octane; however, I typically mix in about 2 gallons of either 98 or 101 octane per tank on track days to up the octane just a tad.

Stock from the dealer its tuned for 91 due to Calif cramp gasoline

Good to hear. The company I worked for is the main manufacturer of that crap Calif gasoline (regulatory limitations, not the company. Company, manufacturing process and QA is great). So, I know the differences in the gas pretty well and that's the primary reason I run the Cobb tune for the std 93 octane we can get in Texas. Love Texas!
