As some of you already know, David Buschur is attempting to run 9s on straight pump gas. This means no mixes or meth, just straight 93/94 octane pump gas. So my question is, how many japanese imports have even ran 9s on straight pump gas? Does anybody know (LS1 swapped RX-7s don't count or anything else like that). I've been searching the internet for awhile and coming up with nothing. What about cars like the Supra and Skyline? Apparently running 9s or even 10s on straight pump gas is not very common for japanese imports and the fact that the 4 cylinder 4G63T is capable of such a feat is just mind boggling.
