378whp 344.7trq FD vs 387whp 420trq EVO vs 500bhp 523trq Viper
Local hang out, Friday night, getting bored.
Talked to a guy who recently had work done to his EVO. Asked him to do a highway run for fun.
The race: 50 to 120, start on the 3rd honk. did it 3 times, he beat me each time fairly consistently. By 120, he has about 2 cars on me.
He showed me his dyno, and it was 387 whp and 420 torque . I don't know about you guys, but this is the first time I have seen a small turbo charged car having more torque than HP. His car is ~ 3400 lbs, and boosting 29lbs on the stock turbo, another .
I have a RX6B single and all supporting hardware tuned to 18lbs, stock ports. Dynoed at 378.4whp and 344.7torque.
Half an hour later, a friend shows up in an 04 Viper, stock rating 500bhp and 523torque, setup a race between him and the EVO. I rode on the Viper, same scenario, 3 honks and we are off. A total of 5 runs, each time the EVO won by half a car. The Viper also weighs in at ~3400lbs, it surprised me a bit, I wasn't expecting over 20% drive train loss on the Viper.
It was an exciting night all in all. Sorry guys but the 7 did lose this time, maybe 25lbs of boost??

few questions....
Were you or the evo on race gas? Did you or the evo brake boost? Do you know how to? I raced a 489awhp Galant VR4, weights about the same as an Evo, and I pulled on him about a car when I brake boosted. If you don't then those cars will get the jump on you and keep it there.

Turn up the boost next time too Also, that torque that he has on you doesn't mean all that much when you're racing from a roll.

^ even though you're at 50 in 2nd it will still take you a little bit of time to build boost as soon as you floor it. Brake boosting is easy to do, and you have full boost as soon as that third honk goes. It really does make a difference, trust me.
Yes, you do brake and accelerate at the same time. Brake with your left foot and press the gas. Keep your eyes on the boost gauge and your speedo. Keep it at a steady speed, play with the brake and gas pressure according to speed and boost. Depending on the speed, I usually see full boost (15psi) while I'm just sitting there. When that third honk goes you take OFF! Try once and you'll see what I'm talking about.

Here is a dyno sheet of a 385awhp EVO I'm sure the average HP over the RPM range is better than a 378rwhp rotary, but you be the judge. The boost will spike to 29 and then taper down to 22ish at redline.

Your looking at 360rwhp and up for over 3000 rpm's. It would be nice to compare graphs.

The highest stock turbo dyno for a EVO is 404awhp, so it won't get much higher than the one he posted.
Look at the graph I posted that's why the FD lost. The car with the highest avg. hp over the RPM raced will win. There aren't any 375rwhp peak rotaries that will average 365rwhp from 5-8K, while the EVO was in the 360-370awhp the whole way.

MY stock twin car makes 345-360 for the whole power band. i would say 360ish is maintained for 1500-2000rpms.
i think i would beat a 380 evo with my car, given the weight advantage, especially on the hwy. I have no idea why this guy lost.

Matty, can you post a dynosheet, so we can compare it to the one I posted? Most of the rotary dynosheets I see aren't getting over 250rwhp by 5000rpms when the peak is 375rwhp.
The one I posted showed 360-388awhp from 4500-7500rpms.

Jasil, here is my dyno chart:
The blue plot is where I'm at, so I wouldn't say that I'm not getting over 250 by 5K.
Matty, I love my car as much as the next person, but I am in no way under the delusion that the FD is unbeatable. And as dubulup said, if you believe you can beat an EVO with 387whp and 420ft-lbs of torque with your car (which by the way beat a '04 Viper with 500bhp and 523toruqe) you are way too full of your self and your car.
