ok, well now i'm thinking about buying a 83 z28 off of my friend, it's got a 350 that he desktop dyno'd it to right around 325 hp. i am wondering with that much power plus lets say a mild cam, nothing huge but something like 272 duration 454 lift. what are the chances? and if i lose what do i need to win.

hot86z-28

oh yeah the new car is auto 700r4, if it matters, somebody has to know.

CrazyHawaiian

well im assuming its a drag race and not a freeway race so a stock 94 supra tt will run a 13.9, beat that and you got him (should not be too hard). But if the supra has any mods then watch out!!

hot86z-28

yeah i found out the 400m time, damn japs cant post 1/4 times, i just wonder what my set up will be running, it's a girl driving, but i hear she is a pretty good driver. i hope i get the car and win the race.

i watched a buddy of mine drag race a supra...not sure if it was TT or not but it was the newest style. He has a supercharged mustang GT with stock suspension so it spins like mad. He spun horribly out of the hole as usual and still pulled a length before the next light (pretty short race) id say top end for a supra TT is pretty nice tho. I swear that mustang would kick some major *** if he would get some traction but nooo alluminum heads and a new intake is next he says

Cuco85T/A

In the 1/4 mile the supra should be faster than a 13.9 with a good driver. More like mid 13s or low 13s.(Car and Driver )
and like CrazyHawaiian said you have to look out for those modded supras. some of the BPU supras can put down 400rwhp.
and that should put it somewhere in the 12s.

There's a guy in our points class who ranges between 13.80's - 14.20's (depending on the weather) in his bone stock TT supra w/auto.

LYV18F

well, since pontiacz28 hasn't said it yet, if you lose to a girl you should sell your camaro and live in your closet the rest of your life...


oh - did ya catch the sarcasm?

hot86z-28

lol yeah i figured he would come saying something of the nature. i'm not real sure when we are gonna race, or if we are gonna race i need to find the money to buy that other camaro first.

You can't go by C+D for actual track times. Their test is with a new car, great weather, and an incredible driver. They almost always get better results than even the car companies advertises. More realistically high 13's for stock, but it doesn't take much to get thesese cars into 12's, or even 11's, so watch out.

Is the supra auto or manual?

if the Supra is bone stock you'll have a good shot, if not kiss your *** goodbye

and DO NOT race him on the highway, he'll leave you like you're driving a neon..

hot86z-28

the supra is supposedly a 6 spd the person wasn't sure, i have never seen the car but have heard about it, so i dont really know. i didn't plan to race on the highway because i know i have the torque, low end, and it has major advantage high end.

Garett92Z

i'm sorry but I don't think you'll take him, hard to say though I guess. My friend has a 94 red TT BPU...

stock they are low 13 second cars... full exhaust, boost controller, intake and these things are 12 second rides it's crazy.

toyota really got it right on that platform.

oh yeah and look under the hood, if the thing is "missing a turbo" then don't even bother racing him

garett

hot86z-28

well now i realize that if i would be buying the same motor mark a. has then i would have no chance... thanks guys... what would have to be done to a 350 tpi to run with one of these

unknown_host

iTrader: (1)

dont get a 350TPI, get a cam and some vortec heads. that will bump compression up having 64cc combustion chambers to like 9.3:1 or so. a cam will help take advantage of that high rise intake you said it had and the vortec heads are supposed to be worth 30 hp over stock heads. that should get you close to at least 300 ponies.

TBI305Camaro

dont those single turbo supras have like 600hp or something crazy like that?

rx7speed

if they are running a single turbo it more often then not means they are tuning the car to have quite a bit of power.

prolly running something like a t-76 or larger and about 20+psi of boost

so yeah 600 hp could easily be gained by a single turbo conversion

TBI305Camaro

thats nutz 20psi?!? I know a guy running 15psi of boost (intercooled also) on a crazy mustang. ran high 6s in the 1/8th with no intercooler and a 12psi blower. Also running a decent shot of nitrous also. And the car is still street legal. They drive it to the strip and change tires its insane.

paul_huryk

I can't figure out that one, typically a single turbo has to be really big to support the airflow capacity of two small ones. On a 3L motor, it takes a bit of time to build up boost on a single turbo, so you get some lag. I would think a good twin turbo setup would work better (maybe not in the easy to plumb deptartment) because you would have more bottom end with the same peak power.

But what do I know, I drive a Chevy.

typicallly those running one single large turbo are pushing WAY more power, T-76's are very popular among the surpa crowd, i'd like to hear the times of the fastest supra still using the TT setup..kinda curious...but those pushing big power use a single big turbo. remember, the supra engine spin up to 8K easily..yeah lag might be an issue way down low but top end, *** damn those things fly...

rx7speed

exactly


who cares about not getting any boost till about 3000rpms when you can spin till 7000-8000rpms


ok just heard of a t04R what the hell is that?


this guy is running it on his bridgeported rotary in japan pushing 25psi... most ppl I know with a t04 are only pushing maybe 15psi or so

what give, I thought that would go pas the turbos ability there

CrazyHawaiian

From this website: http://www.to4r.com/specs.html

The T04R kit is a medium-large HKS single turbo kit capable of 730+rwhp (Dynojet / 860 flywheel horsepower) on high boost.

TO4R specs
T04R Turbine wheel dimensions are 74.2mm/64.7mm
T04R compressor A/R is .70
Available T04R turbine A/R's are .81, .84, .96 and 1.15

HKS turbo inducer / exducer sizes
HKS T04R 66.7mm/84mm
HKS T51R KAI 70.3mm/94mm
HKS T51R SPL 76.5mm/102.2mm

And you can buy one here:

paul_huryk

Ouch, that kit is $4,400 alone. An intercooler for that has to be at least $3,000; not counting other engine/electroncs parts.

Sounds like an expensive proposition, but makes the power possible.

screw that, i'd rather just spend 600 on a TA-49, couple hundred on a deltagate and be done with it, that's put me into the low 11's(probably) which is as fast as i would wanna go..

rx7speed

ok I know a little about turbos

but when you get all tech there I am lost


um....


I'm just curioius about how much lag I would have vs just a normal t4

PONTIMANIAC 90

Actually Supra is not a true TT car like the 300ZX TT w/has 2 small turbos that spool up together. In the Supra the 2 turbos spool up in stages. The smaller one first and than the larger one at certain rpm. Swithching to a single larger turbo allow the Supra to run more boost. Some people convert Supras to a true TT set-up but that is as you can imagine can run you double if not triple $$$. BTW all the other TT cars;RX7,GT 3000 and Stealth are set staged like the Supra.

Cuco85T/A

Single turbo Supras can be made to handle :hail: 700rwhp.
They can also boost up to 28 psi. That would easily put it in
the 10s no problem.

TexasLT1

Hey RX7...my brother is putting a peripheral ported turbo'd 13b in his 68 VW beetle(after he finishes putting the 462 in his 78 T/A) Should be a 9-10 second car when its done...5 speed porsche tranny, porsche suspension...fiberglass hood, decklid, and fenders...about 350-450 hp in a 1500 lb car with great gearing!! FAST....

CrazyHawaiian

Actually I've read about Supras pushing 900+ rwhp @ high boost. Take this for example ... single T-72 setup (still with a stock bottom end) and a 70 shot of nitrous. It ran a 9.81 @ 153.58mph. Street legal and on street tires. After the guy dropped his daughter off @ school, he went down to the tracks and posted a 9. Nucking Futs!!!

http://www.turboimports.com/swst88supra.html

And then of course there is the Walserrz ... I've seen video of him beating stock and modified GSXR1000 and Hayabusa Bikes on the freeway (from a roll).

Yes I give major respect to these IMPORTS.

rx7speed

he fuggin nuts


a PP motor can run about 250-300hp N/A but with a turbo put on it also ¿!¿!¿!¿!¿!


only problem is only high rpm car
and a turbo with a PP would only make it more so

TexasLT1

actually that was my brother that posted that under my name. yeah, he is friggen nuts, he's had that car for over 2 years now and its still sitting in pieces. he talked about getting it running but he doesnt have the money or seem to want to put the time in to do it. I think its just going to remain a dream for a while, but if he does in fact get it running, theres going to be a lot of racers around here caught off-guard. it'd be sweet as hell if he did everything to it like he talks about, but I cant see it happening anytime soon. as far as the high rpm, thats what I tried to tell him, that he'd have to launch at ungodly high rpm's to even get a good start, but once that thing was rolling, or a highway race, that thing would be crazy fast. and in a car that small?! I dont know if I'd have the ***** to drive it, let alone him. guess we'll see...

rx7speed

a PP turbo motor I guess you can do and make huge amounts of power

but he would be better off just buying a larger turbo for the car

that way he can drive it around town still and still get somewhat devent gas
