Ok all I’m just whipping out the measuring sticks here, so if that offends you than don’t read on.

My personal interest is in the engineering of the machine itself. I design and build more than I drive and I want to understand the art and science behind the race more than I want to be on the track. I feel that the best engineer is the one who spends the leaste amount of money and does the most with it. Perhaps Ford or Toyota has that crown… I don’t care to address that particular angle in depth in this post. What I want to know is what the hell is the deal with the Supra…

Are Supras truly as fast as the supra community claims them to be? I’m enough of an engineer to know that it is all about 2 factors. First is burning fuel to make power and the second, getting that power to the ground… So looking at the Supra ; I see it takes 30-45 pounds of boost and with the right fuel pump could perform as well as an engine 2 to three times its size. But that would only put it on par with a vette running light boost. SO where in the hell are these 6 and 7 second quarter mile times coming from and how are they making 1000+ HP on 30 pounds (2 atm) of boost? 2 atm = 3x the stock displacement/power that should be around 700 Hp.

My first theory: Most supra owners are younger and less mature as such, so I’m willing to make an assumption that they are more likely to exaggerate or omit details (lie). Now don’t get all excited if you read this and feel I’m pointing a finger at you. I’m 42 and raised my 1st son, been around many others And most of all I was 21 once myself as were all my friends, so I can look back with a laugh and say that 21 year old and such age young men tend to be a bit more full of **** on average than they will be in the following years yet to come… Maybe they are sliding in 1/8 mile track times and doing some what if calculations to report HP (like what if I burned 80lbs per hour with each of 6 injectors and it was all translated to HP…

Second theory: Japanese engineering is so far advanced that we ought to hire them.

I know it is a forged motor and all: And what each car weighs… so I’m looking for some sort of sage knowledge. I can’t see all the facts and engineering lining up. The fastest corvette is in the 9s with 1500 HP. Weighs in a little less than the Supra and has plenty of good drag radials to choose from. Am I to believe that even a middle of the pack twin turbo supra smokes it?

 

Generally speaking, no.
But some of them can be VERY fast, especially on a high speed highway run.
If you've ever heard of the telephone game, well, that clearly has applied to this particular car. It's starts with a car that ran 11s on stock turbos with aftermarket cams and race gas (true) and by the time the story makes it to the interwebz somehow morphs it's way into a car that ran 7s at full weight on a 100% stock motor and pump gas.
And if you've ever heard of the term "fanboy", it was likely invented because of this one Toyota LOL.
There are still far more 11 second Toyota Supras then there are 9 second ones. And even fewer true 8 and 7 second ones, though they certainly do exist.




Much of it comes from traditional hot rodding/drag racing innovation and tricks (LOTS of power, gearing, suspension/tires, weight reduction etc.) mixed in with some serious modern day computer software/tuning technology.
And MONEY.




EXACTLY.




Ok, you're going to need to revise/work on that one a little bit LOL.
1) the fastest Corvette is not only in the 9s and 2) modern era Corvettes have gone mid-low 8s with less than 1000rwhp.
I don't even think the one that has gone 7s (yes, 7s (atomicfusion's C6 Z06)) has a full 1500rwhp.
I believe that the "1500hp" car you might be referring to is the LMR C6 ZR1 that recently went 9.6@147mph? Well as it turns out someone on You Tube screwed up royally in posting that with totally false information as that car is making NO WHERE NEAR 1500hp. Probably closer to 885hp and that's at the crank (likely less than 790 at the wheels) so that 9.6 is well within the range of what it should be running. And do keep in mind that is a total street car, air conditioning, power windows, stereo and all.

Some are supercharged, some are turbocharged and one even did it with nitrous but consistent 8s are no longer out of reach for a properly built late model Corvette.

 

You need to do a much "better" quality of research. The fastest Corvette is in 9's with 1500 hp?.......I hate to break it to you but a gentelman who goes by the screen name RobZ drove his car into the nines with a NA 346ci head and cam car ......back almost 3 years ago on 93 pump gas with about 490hp with a stick shift. Not convinced? Google "RobZ Corvette" and read the GM High Tech magazine artical from 2009. In contrast... PaulZ ran 8.5 with a twin turbo ZO6 back in 2005. I believe Paul Major is running in the 6 second range with his twin turbo Z, and lets not forget about Tim Lynch and many others.

 

The Supra was over engineered from the factory. The bottom end can handle about 800hp. The tranny can handle about 600hp stock. They swap out the 2 small turbos for 1 BIG Turbo. Get the right fuel and tune and these cars can easily push 600+hp. But, it takes money to do it. Parts are expensive. Mainly because there weren't many Supra's made. I live in So Ca. Capitol of Modified cars. For every 50 Vettes i see, I'll see 1 Supra.

 

Not to mention they have been discontinued for some time now. Stock parts are probably getting harder to find. More than likely, they over engineered it because they didn't want any warranty issues. The reason that motor handels boost so well is beacuse (like you mention) it was designed for FI. The head gasket has a lot of contact surface around the cylinder walls and there are 6 head bolts per cylinder. The LS1-6 has 4 bolts per cylinder, and not as much surface area around the cylinder.

 

True...and the Corvette is still being produced/sold to this day, the Toyota didn't sell well here at all so it was dropped and not long after that ceased production entirely even in it's home market.
That's what happens to cars that are sales failures.

 

Exactly, what I was thinking.
Stock for Stock a typical Mark IV would have its hands full with a LT1 ZF6 C4 Corvette for competition in comparable model years.

Granted they maybe a bit biased but this IS Corvette Forum.

Once you start modifying it comes down to who has more money and who has more knowledge to build a faster car. Then there is the issue of driver...

Another interesting article: http://www.roadandtrack.com/tests/co...orsepower-club

 

I bring that up to people all of the time, some tend to worship the car for some reason but a stock MkIV Toyota Supra was a low 13 second car at best, they aren't light cars.
Yes at the time that was pretty quick for a stock car and like most boosted factory cars it could be modified faster easily enough but it wasn't exactly a cheap car either.
At one point they stickered for over $45k, and this was the mid '90s!

 

That 1st clip is very cool. Does anyone know what clutch and flywheel he is using-as it sound's like it slips perfectly at the start with an easy hit.

Regards,
Steve

 

Again, it comes down to research. But if you must know its a Mcleod single disc slipper clutch.

 

Thank you.

 

Just to confirm. I am 100% Corvette guy...

But here is a Local Model (she) runs a Supra about 9.0 Flat over 150+MPH... I have seen her and her car before. Very impressive. google her... you will like :-)

However... I have witness Paul Major run his Z06 (granted not a IRS rear) before the crash...and he was going 200mph

What I had based my numbers on when I made the post was a comparison of the supra forums and corvette forums 1/4 track time list. I am very surprised to hear a 490 HP vette do 9's ( I didn't see anything like that on the forum list... I'm guessing it was strictly a track car. Perhaps I'm failing to separate the track cars from street cars.

When I do "research" it is very difficult to separate the Bull Sh** from the facts. Nothing I have found on the internet can compare to the knowledge people who have been at the tracks for decades have. So please understand I'm looking for what I don't have (first hand knowledge). The post from supra owners often make outrages claims.

Given all you know, if you had simply to win a drag race and had 30k to spend under the hood, would you go with the supra or a corvette. and why?

Don't get hung up on side tracks (the vette is a better car in so many other ways). I'm just exploring tis one facet...

Thanks for reading.

 

You might want to focus a bit more on some of the faster categories within these two lists, their validity and the info on them is pretty well documented and scrutinized, not too much BS will find it's way onto these lists:

The car had some trick parts and careful attention to detail/fine tuning thrown at it but it was still considered by many to be a street car. I do believe that it was even driven the 40-50 miles to the track and back on some of it's low 10 second test passes just prior to finally going 9s.
The same car has since gone 9.3s and mid-high 140s with a 388 cubic inch motor, still NA, still street drivable.

I was there in person to witness Tim Lynch's record run. Amazing that the car runs low 6 sec on gasoline.

Let me just say that in my opinion there is nothing impressive about anything Toyota. The little Hondas that run 10's and nines is impressive. Its pretty amazing what they get out of those little engines.

 

That is an beautiful car. How much?

From my perspective Corvette, Mustang, or Supra, if you're not using a stock block it changes the game. I don't think a stock block ever made those numbers. Yet I've always been sympathetic to bending the rules for the LS-X block. What was Tims block?

 

My friend Gary White has a supra,every day driver no cage still has air and every thing it came with from the factory.HE CAN DRIVE THE CAR ANYWHERE.It will run in the nines. And if that is not fast enough for you there 10.5 Toyota will run in the high 3's in the 1/8 mile.Just google GARY WHITE.

 

Also his every day driver is a 6 speed drives it every day rain or shine!

 

There are quite few 9 sec vette's that are driven on the street on a regular basis as well as some 8 second ones, and several of the guys do post here on drag racing section. They drive their cars to the track or any place as well and have all accessories. Several were at a recent track rental. Several are stock bottom end cars such as Tommy's car from anger management and Shawn's which are well into the nines. If you like Toyota's, well thats fine everybody has their own opinion....Have a nice day and thanks for playing. This isn't my thread and I really don't want to Hijack the OP. If you didn't happen to read the OP's original post, most of it is copied below.
