Estimated Q/M Time

[suprajunkie08]

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

what R&P?

16.1 @ 85, maybe?

[suprajunkie08]

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.

[supra4life]

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.

[suprajunkie08]

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.
good luck

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

[supra4life]

My stock auto ran an official 17.5.

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.
