The dyno read low.
What horse power would you rate myt car at/

Your crank HP would be as follows:

Assuming:
180# body weight
assuming 1 gallon fuel and mods equal to OEM parts in weight
= 3465 lbs total weight

343 crank HP which means your mods are netting you a real +10 HP gain at the flywheel. Forget the dyno crap because they are estimates at best. The track HP is the real truth of the matter as it is a test based on the real loads experienced by the vehicle.
