Back from the dead...
I'm new, about to pick up an 03 10th Anniversary TR KB Cobra this weekend. Talking to a few people about the benefits of Meth injection for high speed runs and open track. I'm not that familiar with the Cobra setup because I am coming from a Speed INC built 416CI N2O GTO.

Basically there seems to be two thoughts on this. First is that it doesn't benefit you for lowering IAT's and is thus a waste of money. The other opinion I have been getting is that it does reduce temps, but only in the combustion chamber where it can't be measured easily (and thus prevent detonation). All agree it allows for tuning on pump gas (91/93) as if you were using 100+.
So are the benefits worth the cost for someone who wants to do some open track and go WOT on the Autobahn at 100+? I keep reading that cooling is the main concern for this type of driving (open track and sustained high speed high RPM loads). Already has a Gords H/E but I am also considering a larger radiator.
I've got the opinions of Speed INC and Kurgan on this already but reading around various forums it is still confusing since some say it is a complete waste of $$ that could be spent on other modifications that are more useful.
