There are 100 cars on corvette forum that could cover the quartermile faster than that car.

 

I'd be interested to see this. 100 corvettes that run 10's? We aren't counting how fast they "could" go, or how fast they "wanna" go.... And who said it was a competition? Sure there are stock bodied supras that run 9's and high 8's. There are 1.8L 'econobox' civic's that run 9's. ... it's not a competition, they are different cars -each w/ their own pro's and con's. My philosophy is to enjoy motoring; the hapiness cars bring to their owners is all that matters in my opinion. :) I'm not flaming, just expressing my view. Thanks.

 

Sorry but that car couldn't run 10's, sure the power is there, but its not usuable. I'd like to see him run 11's his first time out.

 

Sorry guys, I have to go with Jen on this one. Take it from someone with WAY too much power. Having all wheel drive & low boost off the line is going to be superior in a street situation. Read my post about the 850. Blowers are great, but they are actually too efficient sometimes. Believe me, I will probably have more power than anyone on this forum but there will be cars that can beat me. A properly set up Supra will probably be able to take me in the quarter. Now at the Salt Flats it may be a different story :)

 

Who said there is no room for twin turbo's???

Are you feeling well Merlin? :D
Have you been driving that vette of yours around?

 

Supra's don't have all wheel drive Merlin, and that car's power more than doubles in like 1000 rpms. Sound Performance on Supraforum even challenged him to a quartermile race in a car with ONE turbo small that either of the turbo's on the above mentioned car.

 

I have to agree with Bill. Although a single turbo from an Audi may not flow enough for an 8 cylinder engine, two of them would! Plus two smaller turbos will spool up a lot faster and create a lot more midrange torque than one huge turbo. Besides that, keeping one turbo for each bank of cylinders also creates a much more balanced dual exhaust.

So my vote is to use a couple of small T03 or T04 Garretts rather than some enormous single turbo out of a semi truck, for example.

 

Once a car is in the upper RPM range, "Mid-range torque" does nothign for you. At high speeds, HP prevails. Torque gets you off the line, HP propels you to higher speeds. Like i said above, i think 2 ported 20G's would do nicely on a vette :).

 

Hey got to come in this ,Check the picture what Twinnie posted,does it look pro or what!!! and proud to say, MADE IN FINLAND.... :seeya :seeya :seeya

brgs Joni

 

Yup, made in finland but soon in holland tearing the tarmac from the local streets :D

Oh no, not the TQ vs HP debate.... I'm sittin thsi one out! :jester

Hey Jen, what does a 20G flow in trems of CFM?

BTW, a guy here at work has a ported turbo Eclipse (FWD), running 14 PSI, with a downpipe.
Is this car suppose to have a 20G in it?
What size inlet and exhaust does it have?

He has asked if I would run him. I accepted, just need to find the time. Is this car suppose to be fast?

I would love to see a stock body inmort run 8 or even 10. The only 10 I have seen in an import was a highly mod honda (nitrus the works) looked nothing like stock. I think it was on HP TV. THIS CAR WAS NOT FOR THE STREET.

 

One 20G flows 650 Cfm... So duals would give 1300?... not bad. If that's not enough you can stick on dual 25G's that would together flow 1700 cfm... :)

 

The K03 in the Audi TT 1.8l can only flow enough for about 220hp and I doubt 2 of them would be able to flow enough for a 5.7l motor(Audi S4's which have 2 K03 & a 2.7l motor make about 350hp with a chip and full exhaust). The K04's are good for about 265hp each so 2 of these would work...but why not just use Garret turbos??? The Garret turbo kit for thwe Audis & VW's are making anywhere from 270hp - 310hp on stock 1.8l motors.
( I plan to get one of these kits for my TT)

 

I was talking about Garrett turbos. The T03 and T04 are Garrett turbos.

Jenny, I'll bite. When you're on the street, high rpm-only power is what does nothing for you. Merlin's torque, even without adequate traction, would WALK ALL OVER a twin turbo Supra, while it's trying to spool up. And by the time it does, Merlin's traction comes in and his horsepower curve makes him run even harder from the Supra.

Let's convert over to a twin turbo set up designed to run hard from 2500 to 6500 rpm and compare that with your preferred set up that'll run hard above 5000 rpm. The twin Garrett turbo set up will walk all over you on the street. On the salt flats...okay, you'll probably win. How often will that be?

To all the folks who don't think torque is important and horsepower wins races...they haven't run my big block Firebird. I have been CLOCKED by a cop a week ago hitting 65 mph from a dead stop by the time I left the intersection. Of course I got a ticket. But dang...0-65 mph in the length of an intersection?

Is your high-rpm responding turbo going to spool up quick enough to catch the Bird? I don't think so. The race is over before you get out of your lag.

It's all in the launch. If you don't get a good 60 foot time, you can spend the entire rest of the quarter mile trying to play catch up. Torque wins races.

Don't worry Merlin, you'll destroy the Supras. Jenny, watch out for Merlin.
:D

 

Thanks for the vote of confidence Momo!! One thing I'm starting to learn in life is balance & I think on the street, a good balance is important. If I can ever get this thing finished I think folks will be quite shocked what it can do, but traction is definitely a huge issue. I've always believed that a properly set up big block with forced induction of any kind will always take a smaller engine of equal boost. It seems such a simple concept, but people still reject it. For the street I feel the ultimate setup is high rpm forced induction - so I both agree & disagree with you. The part I agree with is the torque. You have to have the torque to really launch off the line, but not so much torque that you spin tires or break things. With the next car I am going to experiment with a monster block 700 cubic inch car that is tuned for high rpm's with some kind of forced induction that also only comes on in the high rpm's. I think this would be the ultimate street car. By setting the powerband in the high rpm's this car would act like the smaller engines up high & not spin the tires as much but would still have huge torque because of the size of the block. I know it sounds crazy, but I think it would work. Basically take the biggest engine ever put in a street car, set the powerband & induction high in the rpm range & see what happens. It might bog some off the line, but once you got motion & the boost came in it would be a frightening experience.

P.S. Jen's OK... She actually may help be helping me with my stock project so who knows - she might be crazy enough to even want to drive the beast. Wouldn't that freak out the guys at the local track! A cute little gal driving such a wicked beast. Too funny - I would love to see the look on people's faces...

 

P.P.S. Most all out race setups I have seen running turbos use a single turbo. I have seen a few twins, but what they usually do is use one big monster turbo. I don't really know enough about the subject to understand why that is, but they don't seem to have much lag. The technology of these new systems allow them to spool up much faster..
