Hey guys long time no see. Had some internet troubles.
Just wanted to fire this out there but what do you think my 85 supra would run in a quarter? Keep in mind she is bone stock. And with driver weighs in at roughly 3200.
Ive used online calculatorsthat tell me from a best of 15.6 to a worst of a flat 16second run. Whereas i have an american car buff who doesnt believe it can run past a 17.5 in the quarter. And now my friend believes his 89' Cavalier Z24 can bust my nuts since he got a ticket at 16.34 and is convinced my supra cannot pass 17.5 . And everywhere i go it seems that number is off.
However, i just wanted to get your more....experianced and professional opinions when dealing with the supra. Keep in mind again its stock and i run a 5-Speed Manual. :mk2_vroom

16.1 @ 85, maybe?

R&P? lol sorry im a noob xD
And i dont know if this counts for anything but i removed my cat. And i have 2inch pipe(not straight) running into a 2 1/2 inch flowmaster.

R&P = ring and pinion, rear differential gear ratio...My guess is it'll run about 16.5, but you never know till you get to the track.

Yea im not sure where to find what ratio im running? I have a P-Type 85 rear end. So im not sure exactly. But hopefully before i ever hit the track i will have a modified airbox with a rabid chimp intake. Not that it will make a huge difference. But a little more power couldn't hurt.

But any of you guys are more then welcome to come down to Kill-Kare race way. Has a speedway and a drag strip not more then a 20min drive from where i live. And i would love to make some friends on here in person. Besides i just want to have somebody down here that can bust this guys Dodge Neon SRT-4. I know he has it running 13's or low 14's im not sure though.

FYI - official times for the '85 MKII from magazines back in the day were low 16's.
There are several factors to what your car will actually run at the track - things from how healthy your car is, how well you can drive it and the track itself... There are 2 things to understand; there is your cars potential, and then your ability to extract it.
I've have/ had several 14-15sec 5M-GE MKII's - ranging from 14.6 to 15.4; and that is from just intake, header, exhaust, etc to stock. Never taken a MKII to the track that was slower than mid 15's.
W/ an intake and exhaust, a strong 5M that is well tuned (bumped up timing, good plugs and wires, no 'issues', etc) should have a good chance of running in the 15's or possibly high 14's.
But the other factors are how well you can drive it - at the track is much different than on the street btw. It usually takes someone quite awhile before they can reach their cars full potential at the track - so its doubtful that you'll be very impressed w/ your initial results; getting some track time will make one of the biggest improvements overall.
Lastly is the track itself - lots of variables here as well; biggest one is probably elevation. We have five 1/4mile tracks around here w/ in 1.5 hours ranging from 320' down to 16'. I've taken the same cars to multiple tracks and the times vary as much as .5 sec or so.

I got my auto to do an unofficial 1/4 mile (iphone app 'dynolicious') @ 16.3. and a lightly modified 5spd to do it in 15.6

My stock auto ran an official 17.5.
03-23-2009, 07:05 PM
my first day doing the 1/4 mi best of 7 runs, mostly stock with RC intake and CAI through the fender and i think a K&N...

Last summer with no mods once so ever except for a straight magnaflow my car ran a 16.2, and that was with squishy stock suspension. Since then I've upgraded the suspension so I'll get less squat and I removed the cat and junked the stock air box. I'll see if any of that made a difference.
