Thats pretty quick! Why would you think you did something wrong if it RIPS?

Pics/vids, and let's see how long this 'thing' keeps ticking with all the china/ebay warez...

because it just blows my mind that this little 12a would rip so hard i just figured i must have done something!?! it far exceeded my expectations at only 8 psi boost
i just want to crank up the boost now but i know i will probably break something :/
just leaves me to wonder how awesome this cars going to be with a fd,s 13brew
because thats next i will work on getting some pics and vids 4 u guys

awesome car.

why are you so surprised? the 1st gen RX7s were very light and with an engine setup like yours, I'm surprised you're not going faster. maybe with a good suspension setup and slicks, you'll be in the 12s.

this is why the 1st gen is still so popular in Australia for drag racing.

lol not a mullet i grow out my hair for locks for love. but my best time put down was on cold street tires, and low boost, with a bent axle, and it was the first and, last good run. (rear end was shot after this one) i was having fuel pressure issues all day could not boost past 3 psi b4 she would break up on me, so some guy at the track gave me a wrench and i turned up the fuel pressure about 2 full turns on the jam nut (Mallory 4309) and z00m. i have the vid it pulled so hard i missed 3rd gear 2wice. 13.2s not bad for half a sec trying for 3rd :p no jokes. its deff a 12 sec car with some sticky's. but i did not build a drag car she is just for whipping the ****
out of those DBags whose daddy bought them a mustang for graduation. and in the proses she has become quite the monster
