Hello guys.

Here's the question: how quick 500-rwhp MKIII can be at 1/4 mile on street? (not prepared track)

And now whole story:
I'm trying to build high-powered weekend car, as Supra should be. There are a lot of such cars here on SM (450+ RWHP, big brakes, good suspension, stereo and full interior). Some of components (to give you an idea) are: 7M, pt67dbb, FFIM, probe pistons, eagle rods, 720cc injectors, standalone etc..

And now about racing...
We have very sad situation in our country with drag-racing. There are only few (less than 20, iirc) official "tracks" in whole Russia =( I put "tracks" in quotes because these tracks are just pieces of general roads or airfields (except two). No preparation at all! Most of them are dirty/dusty and even have bumps... But we have plenty of racers and I like drag racing (if it can be so called here) too... Why do I do that? To compare my car with others (many people upgrade their cars too) and to show some rich modern fast car owners that old '87 Supra deserves respect too... Yes, maybe this situation looks stupid to you, but it is our reality... =(

So, now more detailed questions:
1) How fast full-weight MK3 can be on unprepared track? I was able to run 13.3 with crappy 2.3 60' on SP61-style turbo... Once I even hit 12.9... So can I run (theoreticaly) 12.5 e.g. with my new setup or it's just a dream?

2) Are there any benefits from drag radials in such road conditions? or it's just waste of money? What tyres do you recomend for my situation?

3) Now I'm on R154 but going built A340 (don't like manual in stop'n'go traffic). Will auto improve my 1/4 mile times? (with 3200 stall, better frictions, improved cooling, etc) How much should I expect?

Thanks in advance for your opinions and advices!

Slicks if you really wanna go fast, Drag radials on a manual trans= wheel hop, But you are going auto so get some slicks Crank the boost, adjust your fuel & timing to conpensate for boost, Do good burnouts adjust tire pressure too, It's all in the how to drag your supra thread... I can't wait to get my supra running!!!

And I assume SupraStick controls it pretty well? Ian, do you recommend suprastick v4 for my application or something else similar? (I have no spare outputs on my engine standalone, so tranny controller should be separate unit)
Thanks!

Get some VHT, it will become your best friend especially if you guys are fortunate enough to have concrete streets over there.

Drag radials will help (or better yet, full slicks) a lot. So will an automatic tranny. You'll drop a second off your best time, more than likely.

Wrong slicks on an unprepped track aka the street will not hook for shit, in fact you will be better off with a set of good street tires. case in point, did this after a 20sec burnout, tried launching.. 285ft...75mph in 2nd smoking the back tires.

Took it to the track, launched a few times and did this....

My opinion would be to get yourself a good set of mickey thompson et street radials, ive seen a few of my buddies pull the front wheels on the street (unprepped) a few time with those... There is no reason you should be running high 12's on your setup, i ran low 12's high 11's on stock turbos with only 395whp in a full weight supra. even on the street the car would hook enough to pull off a mid 12 pass.
