GTM supercharger DYNO

Mike@GTM

I'm not sure if you're familiar with mathematics or not, but he is very clearly making 500hp. We advertise our supercharger as brake horsepower (aka at the flywheel) due to the wide variation in chassis dynos. You see, the OP posted some very useful information that you chose to ignore...namely, his stock dyno graphs on the same dyno.

So, this is where 5th grade level math comes into play...ready?

The OP made 278 whp (that's the average of the four runs posted) with his stock car. Assuming that his car was making the Nissan advertised 332bhp we can divide 278 by 332 to find out that 84% of the power is making its way to the wheels (according to the dynojet).

Now, let's take the average of the four supercharged runs which is 417whp. Now we can divide that number by 84% and guess what we get?

An average of 498 crank horsepower. Sure, 2hp less than our advertised 500bhp, but as you can see from the four runs, it is well with the standard deviation from pull to pull.

No nitrous required for our supercharger kit to make the advertised horsepower...also, no cats were harmed during testing.
