Contour Enthusiasts Group Archives Forums Modifications Duratec Performance Twin Turbo?

Well since we are pulling out the old mopar turbo memories...

I had an 87 Shelby Charger...
Probably weighed a thousand pounds with me in it (okay maybe a little over 2000lbs); 200 HP engine. (not stock of course )

My buddy had an 86 GLH Omni...

We used to terrorize those poor 70's & 80's V8's

WHAT!??!?! i talked to mirko all the time, the amount of $15,000 NEVER came up. maybe if you are talking about ALL or mirko's costs and stuff... maybe... but i doubt it...

one more thing... our cars need MORE low end torque. everyone is so worried about peak numbers and how much hp they make a 7500rpm. who cares. you aren't going to break into the 13s with high peak numbers. you need more at the bottom end, twin turbo setup offers more torque at a lower rpm, which is what this car needs. yeah a single turbo might get you the big numbers, and might do it more efficiently, but a nice sized twin turbo setup will get you the wins, torque rules, and we have very little of it.

More like get off the crack you're smoking.

While you are correct we need more low-end torque, you are nuts if you think low-end torque will get you 13s.

To hit low ETs, you need top end power. When do you hit 0-4k (that's what I consider low end) RPM when you run the 1/4? In first gear, for about 1-2 seconds. Rest of the run you spend running the motor WOT at 5k-7500rpm. That's not low end torque.

How about this, I'll give you a motor with 250lbs of torque between 1-4k rpm, then you get a 'measly' 180 ft lbs from 4k-7k.

See what you run. You'll be happy to hit mid 15s.

Gonna agree with JV here....

Give me a set of slicks, and a 100 shot of N20, and I'll show you 13's with my whopping ~140 ft/lbs of torque.....

Once again, if torque is the deciding factor here, why don't we all just buy caterpiller graders and get 9's out of em....

I don't ever see below 4k at the track! Why would you?

HP for racing
TQ for cruising

that's funny... i don't remember anyone talking about spraying a motor, i thought we were talking about turbos... just so you know, a 100 shot of n2o is gonna give you some torque as well.... :rolleyes:

first off, our 60' and 330' times are pathetic, WE NEED MORE TORQUE. the car does not have enough torque to get up off the line fast enough to break into the 13s without some serious high end power... 400hp.... which i still say is pathetic if it takes 400hp at the crank to get a car that weights just over 3000lbs to touch the 13s. the car needs more torque all across the band, but i say no one short of 400hp will be consistantly hitting 13s without 400hp, unless they have a nice amount of low end torque. look at david z's car. he has TONS of torque, and i believe he is one of the only people on this board to actually see 13s at the track.

and that statement about catapillers, just goes with the overall atitude of this board, ignorant and childish.

i never relized how childish most of the people on this board are until i started checking out the f150/svtperformance boards.... people are so much more helpful and mature. they don't have this "if you don't agree with me i am going to flame you make useless childish commements until you do agree with me" instead they provide facts and technical data to help you understand where they are coming from.

just my two cents...

A lot of low end torque sucks on a front wheel drive car...so therefore it's useless. You'll spin your tires all day.

Sorry but a lot of low end is not needed for drag racing...if you are street racing up to 60mph, then more low end would be great...

Shoot, I thought we were talking about turbos. What happened?

Anyway, maybe I can offer some insight regarding to the horsepower and 1/4 times. In drag racing, what you need is the maximum area under the curve in the range of rpms you are in so you can use all of your power to move you down the track. A car with all peak number will not do too good in drag racing nor will a car(diesel engine comes to mind) with a lot of torque down low. What you need is a compromise.

Let's take all of the s/c svts and my car for example since the peak numbers are similar. My car was making 270 rwhp a year ago and most of the s/c svts are making the similar numbers; my car weights 3400 lbs while the contour weight 3100 lbs. So on paper both cars should turn similar trap speed(not E.T. since rear wheel drive have advantage in traction). But why is my car turning 104-105 mph consistantly while the contours are struggling to get 100 mph? And my car is 300-400 lbs heavier. It's because the better low end torque(250 ft/lbs of torque at the wheel from 2000 rpm and up) and the flatter power curve(250 rwhp from 4.5k to 7k). I can utilize my power in a longer period of time than what the svt contours can(270 fwhp@6800 rpm or so).

Anyway, I think I have done enough blabbing for one day. And don't feel bad about no one is doing a turbo kit for you guys. Us cobra guys are still waiting for the Incon twin turbo kits to come out. It would be nice to have 450 rwtq with only 5 psi. /me drools

well said tcobra! thanks.

btw, I may still try to get that spare Auburn and 4.10 off of you, even though I don't need 4.10, but I'm sure I can trade someone for some 3.73's then I just need some 31 spline axles!
