Had the Dart on the Dyno last fall.
It had 350HP and 400 ftlb torque at the rear wheels.

Just out of curiosity What would an estimate be at the flywheel?

I agree with kim.....20% is the number I've used as a general guess. But, dyno's are dyno's...lol. Car weight and 1/4 mph will really tell the story, imo. Sounds like a nice strong street build though. :thumbrig:

Around 420 HP sounds right (give or take a few horses).

Thanks.

The old GTX makes 830 hp on the pump, and on the rollers with a full ex system with tail pipes it made 700 hp..
From what I've seen stick cars run at best 12% to as high as 18%.
Now auto cars are all over the place,depending on the condition of the converter and how restrictive the ex system is..
A customer took his 600 hp 440 Cuda to a chassis dyno and it made 395 hp at the wheels.This is an 11.50@118 mph 355 gear car.
This would be a car with an unhappy converter now,
just my two cents...

Chassis dyno #s are all over the map. Different brands, operators, tires, tranny condition, ect....

Much like flow bench numbers, they should only be used in A-B comparison testing. There are a few chassis dynos around here and the variation between them is ridiculous.
