FR-S BC 7

+5.0 points (supercharger)
+1.5 (Hancock RS3 or star specs tires)
+2.0 (coilovers)
=========
+8.5 CC 5

To compete with just a simple Mustang GT, we're looking at the following

Mustang GT BC 6

+1.5 (tires)
+1.5 (brakes)
+2.0 (coilovers)
=========
+5.0 CC 5


So, this kit is going to have to compete without weight reduction. I don't think that's going to work with the numbers here.

220whp = ~260 at the crank

With stock car weight of 2750 we have a power to weight ratio of 10.5 - a Mustang GT has a power to weight of 8.73 (~3600 curb weight and 414 bhp), a BMW M3 has a power to weight of 8.2 (~3400 curb weight and 414 bhp).

I just don't see how all that lines up, if we're talking competitive, within the same class. Now if we start taking weight away from the FR-S, add e85, it starts to look much better but that also puts the FR-S another class higher.

I'm shooting for at least 270whp. That would give us better power to weight than a Mustang GT & fancy pants BMW, and should give us a chance to be competitive with the big dogs (assuming supporting mods are done). So far only Vortech & turbo kits can achieve higher than that. But I'm holding out for innovate as I think it has a good shot.

Keep in mind, most of the small turbos are achieving torque curves matching (or better than) the dyno posted of Innovate. Now I give you, this is a great cheap easy to install kit, that gives somebody awesome drivability. But if I'm going forced induction, I'm looking at what's going to make this car competitive with the big dogs, otherwise I'll stay N/A
The car can be 2515 using the 0.09 rule without taking points for weight reduction..also your formulas all assume onlt one vector.
Think of your car handling like it does but not giving up anything in a straight line...thats where the HUGE S*it eating grin comes from under your full face helmet. It comes from you going through a corner and catching the M3 getting to the straight and he doesn't just dissapear in a straight line...he stays RIGHT where you left the corner...oh thats right you will out break the s*it out of him in the next corner entry too! WOOT WOOOT FUN FUN FUN!
