Purple Supra vs Blue RX-7 [additional footage]

here's just another video of two cars driving at the speed limit. this was actually the first take, it wasn't posted before because of the stupid commentary of the passengers in the car when the supra backfires.

Good observation. No, it's not nitrous. Even stock RX-7's run richer than most cars. With an A/F ratio of 12:1 as opposed to 14:1, they naturally run rich. At full boost, the secondary injectors in the RX-7(850cc) come into play, but the gas doesn't get completely combusted in the engine, the white smoke is the excess gas being burned in the exhaust line.

*note* don't run a alcohol based fuel additive in a 13b u will fuck the seals found this out the hard way, one reason i switched to Toyota u can completely rape a stock supra block with boost pressure it will withstand they truly are the gods of imports, i know guys running 24psi+ on 700+hp Supra's on stock bottom end its quite a feat

0:06 sounds so gay..

@sodaann can you please read the top comment. NO PISTONS.

@sodaann ... But the RX7 doesn't have any pistons.

@sjoey

if you run an engine at 14:1 your going to melt the pistons. and wtf is an exhaust line?

@sjoey Dam someone who actually knows what they are talking about THUMS UP

@sjoey : Your correct that they are ussually tuned richer, but not 12:1. Try 10.8-11.1 MAX on a 2 rotor running big boost. Also, not even N/A cars run as lean as 14:1 AFR. That is near stoich, but too lean for most engines. Any high powered turbo car should be in the 11.1-11.8 AFR range. The rotory tuners ussually add a bit extra fuel for safety measure because the apex seals can be damaged so easily.

at the same time to rotary motor burn oil due to the way the engine operates
