Had a ton of runs today. But i was dealing with a heat soak issue. My times would be a full second slower if i just did a hot pass. 90F ambient temps, intake temps were 100+ at the start lines. That plus having to deal with a ton of wheel hop if i spun the tires.
Basically what it boils down to is this car is not meant for the straight line. Though this car is a blast in the twisties. If i had 60F temps, with a bigger Intercooler i could have hit 13.4 i'm sure.
Car is set up with Megasquirt II, using launch control and flat foot shifting. Mod list is pretty long, so i post the relevant stuff:
Stock engine internals. 12psi. FM kit, gt2560 (ported and polished header turbo (cold and hot side) and cast downpipe), MBC(junk need to get EBC working), turbosmart BOV, FM 2.5" Exhaust w/ test pipe, MegaSquirt, AEM wideband, 750cc 5o injectors, Mishimoto 3 row(huge) radiator, and Mishimoto slim fans. ebay front mount FM stage 1 clutch. 195/50/15 Yokohama S-Drive tires, Bunch of suspension stuff / tons of chassis stiffening, full brake system upgrade and other miscellaneous things.
Car is a 94 r package car and has a full interior, and trunk, with the spare tire.

Is the Mazda MX-5 Any Good? - /CHRIS HARRIS ON CARS
Chris Harris has been known to not like the Mazda MX-5, even calling it
dirty words in an article a few years back. Now he gets to support his
point by swapping his Ferrari 599 with Cameraman and Editor Neil Carey's NA
Mazda MX-5. Was Chris wrong a few years ago?
