I was at a car show a few day ago and I saw a 98-02 Trans Am with a twin turbo set up on it. I saw the guy open his trunk, so I asked him once he was done doing what ever it was he was doing.. "How big are those turbos?", he rosponded by saying that they were 10lbs each. I then asked him what else he had in it.. He said SLP Loudmouth exhaust, Cam, headers, and it was a 402 stroker (or something like that..). I asked him if he put in on the dyno and he said no, but he figured it had around 750 horses to the rear wheels. I was pretty impressed, but I was a little bit suspious. I thought that was a lot of power for those few, but big things he did to it. Could it be possible that with those options it can put out that much power, or was he over estimating?

If someone can tell me how to take a video off a camcorder that uses video tapes, I can post a video of it.

 

a twin turbo 402 could definitely put out that and more.

 

there is a guy on muscle car evolution that has a twin turbo stock cube putting down 720 to the wheels, so i think 750 on a 402 is a bit on the low side unless he just ain't pushing that much boost.

 

that guy did not know what he was talking about...someone built the car for him lol.... you dont tell people how big a turbo is by how much boost you are running... and you dont have headers on a car with a front mount turbo setup, you have exhast maifolds that go to the turbos...

but yes a 402 with twins could have 750hp it could have 1000hp or more as long as his drivetrain can handle it.(assuming thats a built 402)

 

Could have been on the level but I find it suspicious that that setup wouldn't have been tuned on a dyno therefore giving him "accurate" numbers.

 

Why? It would be much easier to street tune a TT car. Dyno tuning usually just goes for peak numbers.
