Edmund's did an excessive dyno test of the F10 M5 and found that after a double-digit number of runs in high heat, full throttle pulls to rev-limiter, the intercoolers were barely even warm to the touch. BMW definitely made sure that the new turbo cars are up to snuff.

Not to continue posting as a BMW fan boy BUT I do remember watching an official BMW published video about the new M3/M4 and they specifically mentioned that significant design time was spent to ensure that the car has sufficient cooling of the entire driveline during track conditions as not to hurt performance and…

Hellcat makes more power and doesn't pull timing in these situations, plus the reports are that the knock sensor is not triggering nor are any other readings standing out as unusual at the time power is being reduced.

Why yes, in fact I have. I have never experienced this sort of problem. And I live in southern Louisiana and it gets pretty hot.

195 without the aero still sounds slow. ZR1 with less power and torque had to be electronically limited to 205mph. And it had a full splitter, aggressive rear spoiler, underbody tray, etc.

Per Road & Track:

OK Chevy corporate apologist. So why is it that other cars don't have to "pull timing" to prevent detonation after just a couple laps? Is the LT4 really that much of a kleenex motor?

Yeah emissions doesn't make sense.

After several laps on the track or a few hard acceleration runs on the highway, owners of the brandy new Super Vette are reporting noticeable power loss from the supercharged LT4 V8. Originally it was thought that it was heat soak from the supercharger, but, it is, in fact, conservative tuning of the ECU to help the…

So let me get this straight. Chrysler can get 700HP port-injected motor to maintain emissions and pass all durability standards in a heavier car without de-rating engine power, but Chevy can't with their brand-new DI engine?

EXACTLY... all this build up and then... nothing... no follow through...

Are you trying to say that the Z06's "performance issues" are like certain Hawaiian shirt wearing 50 something's with money to blow?

Atleast do like ford does and have the track key...
