I'm a little curious about my car vs. a stock or mildly modded turbo Supra. As far as year goes I guess any year Supra would be fine. I'm fully aware of their high horsepower capabilities with enough money.

I have a 88 IROC-Z 350 with lots of mods & I've been continuing to work on it. I've put more than $2,300 in it since I bought it last year for $4,000. I've taken care of it as much as one guy can. I want to know what do you guys think my chances of winning against a Supra would be with my list of mods and with it being tuned & dyno tested.

CAI, K&N Filters, AC Delco Platinum's, Omni H.P. Wires, Falken UHP tires, custom chipped, AS&M intake runners, throttle body spacer, TPI air charger, gutted airboxes for increase airflow, new 80 series Flowmaster exhaust with new Maremont aftermarket pipe, Borg Warner I.C.M., ASC heavy duty water pump, Ready Rad radiator, new Friction Master ceramic brakes (for stopping power), etc. There is more but these are the ones I can think of at the moment.

Quick Stock Car specs for further analysis: G92 performance package which is the 3:27 Borg Warner rear gear, modified McPherson strut & suspension system, 4 speed auto/O.D., weighs 3,352lbs. without me, with me it weighs 3,567lbs.

I dynoed my car last summer before I had my AS&M intake runners, throttle body spacer & air charger installed and it dynoed @ 282rwhp & 350 ft. of torque. After I had my new bolt on's installed I haven't had a chance to dyno yet. However, I just did the math & you can figure it out for the total so far.
25HP - Intake runners, 30lbs. torque;
25HP - T.B. Spacer, 10lbs. torque;
12-15HP - Air Charger by Hypertech.

You made 282 rwhp with those very minor mods???
I dunno man. Sounds fishy to me.

yeah, would be surprised if that was crank HP even

you would get rocked by the 94 SUPRA!!! you would be lucky if you could beat a WRX STI

I had a friend ride with me one time, he said it sounded like I had a small cam but because I'm the 4th owner of the car I don't know if it's true or not. What I can say is that ever since I bought the thing, even before I put alot of money into it, the car doesn't lose breath like most of our L98's do at around 4,000 RPM. You know what I'm saying? Camshaft work does help..... but intake runners, T.B.S. & Air Charger bolt on's aren't small power gains, so whatever small loss I take through the crankshaft on it's way down is minimal. Explains why I beat some newer cars when we went on full out races on the roads. Whatever the former owner(s) did to this car, it doesn't look old nor does it run that way.

My friend owns a 2004 turbo charged WRX STI. I've rode with him in his car several times. I've been in it when he's raced it. He wins alot of the races but I asked him one day what he would think of us racing. He told me that it'd be a close race. He said he'd probably beat me & would step into 5th gear if we started heading into really high speeds. He has a fast car, better believe that. He has also rode with me in my car too. So he knows how fast my car is too.

282 rwhp and 350 torque would equal about 350 hp and close to 440 torque at the crank. It is a bit hard to believe that this is the case with the modifications that you have mentioned in your post. Are you certain that this is not fly wheel hp?
As far as the additional mods are concerned, hp is not additive. You may be lucky in gaining 20 hp out of a better flowing intake, but that will not be the case if you don't have a good flowing exhaust with headers.
The Hypertech aircharger is probably going to yeald only a few hp at the wheels.
I also very highly doubt that you will gain 25 hp with the TB spacer either.
Now, assuming that more has been done to the car, like heads, cam, along with a custom wide band tune and necessary supporting mods, and you are truly making 282 whp and 350 torque, you should have no problem beating a stockish 2JZ twin turbo supra. Those cars do make good power, but they also weigh alot more than a third gen.

0-80, I think you'd have it, anything after that, he'll take you out...

CamaroIROC88350

I have a full exhaust except for small block headers (which are next on the list) and I don't have a pulley kit yet either (next on my list). The spacer is definitely 25HP and when I ordered mine it came with a dyno sheet to show the proof. Otherwise I never would have ordered the dang thing, you know? With the intake runners that's 25HP & an additional 30ft. of torque. Here's the website I ordered them from if you want to take a look. They're for the 85-92 Camaro's.

0-80? Okay, so you've never ridden with me before, so I can understand that. But my car doesn't stop going or pulling after 80, in fact it keeps throwing down power well into the 100's. Off the line is the easiest & staying in front, that's fun but I've lost to a Scion TC turbo-charged before. It was last summer before I got my bigger mods done.

CamaroIROC88350

Like I stated to another guy up top, I think a previous owner had a cam installed because my idle is not stock (I've compared it to stock L98's of the same year by watching those youtube videos) and the car doesn't lose breath into higher RPM ranges. I think alot of things have been done to it that I don't know about, which sucks in part because I would've enjoyed doing that myself.

I've got so much car crap at my house, it's ridiculous. In my car, in my Jeep, I can't even find my S.S. Card!

I do alot of my own work on my car because I like to learn & I don't want to pay anyone to do stuff for me. But to install a camshaft, headers, and more is something that I would want to do. Take that engine out & go to town! I need some valve stem seals installed because mine are burnt up.

84firebird383

That isn't how it works.

CamaroIROC88350

iTrader: (1)

Yeah, that's how it works. Take into account the small loss through the drivetrain making it's way down to the wheels.

Twin_Turbo

iTrader: (25)

No that's not how it works, you can't add the numbers like that. Same BS as people w/ 300HP from a chip & a filter...come on now!!

84firebird383

I was just trying to help. Go ahead think what you want.

CamaroIROC88350

iTrader: (1)

Yeah, I know that you don't get 300 from a frigging chip & air filter. No crap. I've got way more than just that. Just because I don't have a frigging supercharger or nos or headers yet doesn't make what I'm saying nonsense. And this thread is getting off topic guys, I asked one simple question about a race. Not all of this other stuff you guys bring up. I'm fully aware of what power gains I can make and NOT make with mods, cooling upgrades, etc. If you don't like my thread or you don't like my mods don't comment. There are plenty others who'll answer the thread.

CamaroIROC88350

iTrader: (1)

Read my reply to the other guy. I'm not thinking what I think. I've got the paper proof for God's sake. No crap you don't make 300 from a filter & chip. I know that. But I've got way more invested thus far than a stupid chip & filter. I don't spend my dough on b.s. parts to get nothing out of it. The only way to know anything for sure is to race, from a dig and from rolls. Dyno testing & taking it to the strip too.

CamaroIROC88350

Some of us actually do our technical research on mods before we buy them. I spend an average of 3-6 months researching mods through these forums, online, in person & the actual parts specs before I end up getting something, or not. For example, Street & Performance (which we've heard of) makes the throttle body spacer I have. It's 25 horses & 10 ft. of torque from that bolt on & that makes alot of sense for what it is. Ask my car how it feels, it'll show you. The S&P part I bought a few months back came with a dyno sheet that you get when you order the part. It shows the gains for each particular car that they make it for. Anywho, if anyone wants to just answer my simple thread then that's fine. I'll be glad to talk & listen but to the others who want to just bash my mods or call them nothing, well fine. It's not like I got some stupid Ebay chip (which are crap) and a filter & called it a day. Jesus.

bigred75

if it was like a 94 to 96 hands down you would get stomped. i love camaro's with all my heart. but my friend drives a turbod 96 and well lets just say he isnt slow....in any form of the word. those cars are very easy to make nasty fast and all he has done is tuned it and rebuilt the motor with forged internals and diffrent turbos and he is running 10's i believe. either way it would take a little more than a 350 to get a turbo's supra. now the old year models u could prolly wax. i know that my car beat like an 80's model n/a supra.

I think you've got the wrong idea. I don't fall for that crap & I appreciate your feedback.

CamaroIROC88350

iTrader: (1)

Yeah, I agree. The Supra's are light as heck, at least they appear to be that way. I think they weigh around 2,800 lbs. or so. I like em' alot myself.

Saculia

iTrader: (1)

No,
Actually supras are heavy cars. Especially the newer ones, 93-97. They weigh 3500 pounds and make 320 hp and about 330 ft lbs of torque in stock form. I believe they run mid 13s in the quarter with 0-60 in the low 5 sec range. This approaches LT1/LS1 4th gen category.
A well modded L98 will run that fast. However, like it was pointed out, unless there was a good bit more put into your engine than what you have described, you will not make that kind of power.
Your mods are only as good as your worst bottle neck. Doesn't matter what you do to your intake, if you have a restrictive exhaust, you will not be making as much power. You can't put air into an engine if you can't get air out. This does not mean that you don't have a good cat back. Your restriction would be at the exhaust manifolds.
Now, is it possible to make good power with the stock exhaust manifolds?
Yes, however it takes a hell of a stout combo to do that.
Most of the power gains in our SBCs will come from improved heads, even if a stock camshaft is retained. One only has to take a look at the stock cam specs of an LS1. A head cam swap is even that much better. A cam alone with restrictive heads is not going to do as much good.
Now if you have CIA and larger runners, but restrictive intake base and plenum, stock heads, cam, and stock manifolds, you will see very little gains.
However, if you have the mods you mentioned along with a good set of heads, a larger cam and headers, the mods you listed will amount to more power.
This is the reason why you can not add things like you were saying earlier. Every time you improve something, another bottle neck shows up. In order to gain the full potential of the mods you are putting in, you have to improve the whole system.

Best thing to do is take her to the track over at Gateway and see what she does.
Just my .
Best of luck!

danziger

Dunno if you are serious or not, but here goes...

I can't think of many people that would do heads/cam and then leave on the factory exhaust manifolds and unported lower TPI intake. 25HP from a TPI throttle-body spacer is absurd...

The MKIV Supras (1993-98 in USA) are no joke. 320HP stock and capable of nearly 500RWHP while retaining the stock twin turbos (BPU = Bolt-on Performance Upgrades). The big single-turbo conversions (APU) can reach above 800rwhp on the factory long-block... They are a little heavy and were designed more as a GT than a full-on sports-cat, but handle/brake well enough. There aren't too many stock ones still running around, so good luck...you'll need it.

LOL@a spacer giving 25hp....you can't really be that gullible. Just because a company gives you a fancy dyno sheet doesn't mean it'll give you that power on YOUR car. EACH car is different, each combo is different. Regardless, a spacer on a mildly modded TPI motor isn't going to give you 25hp, just isn't happening. How the car "feels" is completely irrelevant.

Intake runners aren't going to give you that gain either. No offense but you sound like a ***** adding up potential power gains because a catalog says so.

As far as your RWHP goes, you are NOT putting that much power to the ground with the mods listed, it just isn't happening, PERIOD. So either you're not being truthful about the numbers or there's a lot more work done to that car than you know. I'm not trying to start an argument or flame you but that's just how it is. People are getting on your case because you're coming in here like you know exactly what's going on with your car and you're not about to hear anything otherwise. Just because a company claims this, that and the other doesn't mean it's true for YOUR car. Here's an example. How can **** companies like Jensen make claims they have 1000watt amps and yet a good quality amp pushing out half the power works better? Because all that amp has to do is hit the benchmark once in ANY scenario, in ANY set up and they can claim what they claim. Motor parts are no different. Those runners very well may give "A" motor 25hp, but who's to say it's not a AFR headed 383 where the runners are an actual weak link? That's obviously above and beyond what your motor is. See where everyone is going now?

Why are you using a Supra as a benchmark? It's a bit odd. A mildly modded 94-96 Surpa "should" walk you. Then again "mildly" modded is a subjective term.

zachkuby87

what they said u sound like a dumb *** that can read a brochure congratuations. if u can get 25 hp from a tb spacer i should be able to get like 35-40 hp with this really cool shifter **** ive been lookin at.... lmfao

If you race a mkiv Supra, do not do it from a roll.
My buddy had a 95 Supra TT Automatic and with a t-bleeder mod, 4" exhaust and 3" downpipe, Boost
Cut Controller, it dyno'd 395 at the wheels and ran 12.6 @117mph. car was slow out the hole but picks up speed like a raped ape.

I raced my brothers low 13 sec Trans Am on the highway from a 70 roll and tore him up. I was about 100 cars ahead when I shut down at 170mph, and at 170 the Supra was still pulling.

It's like the old saying, what's the difference between a 400hp and 600hp Supra? About 2 tenths.

I thought it went "what does a 400hp mustang and a 900hp supra have in common?

12 sec timeslips!

tealcamaromanrs

so what did your car run at the strip????

toolegit86

as long as the supra was a 7mgte (older i think under 91) you have a chance. but if its a 2jzgte i would not do it. they are a strong car and make power very easy. even the autos are strong. the 6speeds are pullin basterds!! there is one we raced with that is a 6speed with hks cams a single turbo running like 780whp and he wants more.

sti's/evos the luanch is what makes them awsome. there strong sound cool but have a short life span! both cars are very fast and can handle very well.

CamaroIROC88350

Yeah, I hear you on that. Supra's are bad a@@ and I'd like to own one eventually but they're expensive. I'd probably pick up a early 90's model & soup her up.

CamaroIROC88350

Before I really started to do any kind of work on my car I took her to the Gateway last Spring. My car ran a 14.0 even. I ran against a 96 Mustang GT and beat it I guess you could say. It was the 1/4 mile, so not really a race race to me.

CamaroIROC88350

ntomsheck

iTrader: (1)

If you want to beat some of the later model supras, skip the little upgrades like pulleys and TB spacers. I'm not here to say they don't add power, but I will say the power added to dollar ratio isn't that great, compared to a fantastic head/camshaft combo. The best power/dollar ratio would be nitrous, if you motor can handle it. If you're runnin high 13s or even a 14 flat, a 150 shot will drop you down to low(ish) 13s, assuming you have suspension work and can hook it.
