Questions about hp/torque claims (archive)

You state that with your M coupe modifications (i.e. Shark Injection, rev limiter removal) the horsepower rating has gone from 240 to 264, and the torque is up to 276.

How did you verify this power increase? Did you dyno the car before and after modifications? What was the rear wheel hp before the modifications? What %driveline loss did you assume to calculate the horsepower ratings "at the crank."

I'm as curious as others since aftermarket suppliers can make some pretty outrageous claims.

Car is in excellent condition that has been garaged every night. I hate to sell this car though must do it to get into a new house. $33,500 OBO.

Here are some highlights on the car:

* Interior is in great shape, with very little wear on the carpets or seats
* Shark Injection has been applied...though can be brought back to stock
o Removed the speed limiter
o Increased the rev limiter to over 7000.
o Horsepower has been increased from 240 to 264 with torque increases from 237 to 276
* Titanium Cavallino Ti-130R Shifter has been installed, though can be removed and the stock shifter placed back.
* I have applied Zaino Brother's treatments and polish on a weekly basis
* 6 CD Changer installed
* Flip-up moon roof
* Cup holder
* Chrome Package in the interior

Over all this is a great car that I have painstakingly maintained. Only serious inquiries please. Contact me via email.
