I found the MSS superior to the re11, ESP on a long fast track like wgi.
The best pure track tire; r6 hoohoos.

The weather finally cooperated and I had an opportunity to run the new R-888's at the track this weekend. Whereas I had been turning 2:08's on the RE-11's, I managed a couple of 2:06's with the 888's and I think there's probably another second or two lurking within them. They don't provide the audible feedback the 11's do but they breakaway at the limits very predictably and overall the level of grip is certainly superior as one would expect. Definitely a step in the right direction. 
Also installed an OBD2 gauge from Brockway Engineering that can monitor 23 different engine parameters and display 4 at a time. I chose Intake Air Temperature, Engine Coolant Temperature and Air/Fuel Ratios on Bank 1 and Bank 2. IAT's reached 170+ degrees and I'm not sure what is considered excessive. Any informed opinions would be appreciated while ECT's climbed to 232 degrees. Ambient temps were in the high 90's. What is interesting about this is the coolant gauge in the instrument cluster never budged above 175 degrees lending credence to the thought that it's a dummy gauge with limited real value. Eventually I'll have another sensor installed to monitor exhaust gas temperatures but that's another project for another day.

It was great seeing you out there this past weekend. Your car really looks fantastic and it's definitely moving out there. I've thought about it and I'm pretty sure the limp mode is a result of the high IAT's. Even though ambient temps were in the upper 90s Sunday (hotter than Saturday), the measured temp in the staging area and on track was 115F+. 170F IAT is way up there. The highest I've seen on my Dgauge for IATs was the mid 140s and I've never had any issues. You must be really heat soaking everything as the day progresses. Is your Evoms intake aluminum? I know on my car, RUF uses double walled insulated intake pipes made out of some type of rubberized composite material which keeps the heat from elevating the intake air temps. Maybe some type of a heat insulating wrap might help.
Another issue may be the intercoolers. Some of the big heavy free flow aftermarket types will act as heat sinks and have a difficult time cooling off quickly. I use the 997GT2RS ICs which have the composite endtanks and have been proven to have some of the best thermal recovery out there for cars that get used in a track environment. These ICs have a very dense aircraft quality core and are very light. Something the think about.
Hope you get it all sorted out. See you out there soon!

John,
Thanks for your thoughts. It's clear that I'm going to have to keep an eye on the temps and determine if Sunday was an anomalous situation or something potentially more chronic. I'm running an IPD Y-pipe and plenum and Evoms Clubsport intercoolers and headers. IPD makes a thermal wrap for the turbos and headers advertised to increase performance while offering the side benefit of lower engine compartment temperatures. I'd like to speak to someone who has actual experience with them. I not familiar with other companies which may manufacture similar products but I haven't spent much time investigating it yet either.
Also, congrats on your DE victory this weekend!!
Sub 2:00 minute laps was really moving and gives the GT3 drivers something to aim for! See you at the Sept. DE if it hasn't started to snow up here by then!

Keep an eye out for those R888 and a tread seem splitting across the tire. When the R888 wear out go get some Nitto NT01's and you will enjoy even more grip and much longer wear. The R888's heat cycles out in around 5-7 track days. R888 is the worst of the r-compound tires.

Was at the Glen with R6s this past weekend. I'm freakin' hooked. Only problem you get so fast it's scary with slower cars.
Here's a video of Saturday. There weren't a lot of cars, I just caught everyone
