how much horsepower?

StripedStangLX · 03-13-2001, 09:51 PM

My mustang contains the following modifications, but i don't know what to estimate the horespower at.
-E303 cam, 1.7 roller rockers, underdrives, 1 5/8 long tubes, BBK off-road H pipe, flowmaster 2 chambers, 9" K&N cone on a 75mm Pro M mass air meter, 24# hr injectors, no ac, 160 thermostat.
Before i got the car it was raced, so it may have port work but i am not sure. It has 3.73s also. I destroy my friends 89 which has an AOD w/ shift kit, 373, BBK shorty headers, and flowmasters.

-What kind of power do you think my car is putting out?

This will probably get moved to Windsor Power Forum. Im no expert, but Id say about......456 flywheel, and about 421.8942 at the wheels.

No seriously, Id say 250-260 at the fly?

I'd say Stoplightwarrior is pretty close. I think 260 would be a tad optimistic. Assuming that you're engine's still pretty efficient (i.e. good rings, seals, etc.) i'd say you're in the 250hp range.

I'd say an extra 35-40 HP at the flywheel.
