Fuel starvation, who else?

Whereas fuel starvation you lose all throttle regardless of RPM. It can be for just a moment, or it can be so severe that it last a few seconds... if it last a few seconds, you have a very good chance that the motor will turn off all together, which has also happened to me on the track

hmm.... i'm not sure now. from what you're describing, it now sounds more like limp mode, since it only does it above about 5k rpm. but the weird thing is that my temps are only around 220 (cooled back down from about 280+ in a previous session). and it only does it if i'm "pushing" the car hard. (will not cut out if i gently roll on the throttle - in which case i can rev it all the way up to redline).

boosted, its still probably starvation, especially if you are getting it after right hand turns.

In my case, I think I have gone from having it happen around 1/2 tank to 3/4 now because I switched from used R888s to Goodrich R1s. The grip is awesome, and the new brembos really rock.

spl parts sells a surge tank kit, but I don't know if I have the patience to install something that complex, or if I want to pay someone else to do it for me.
