the UR alluminum flwheel says 15 to 30 hp average, im thinking if i get the ypipe(approx. 15hp) and the UR flywheel, i should have about 220+hp to the ground right? with a good launch, is it possible that i could run mid 14 or better. just thinking, hmmm.

 

No. The Y-pipe helps the engine develop more power. The light flywheel does not help the engine develop more power. You won't have 220 hp to the ground, you will have 205.

The advantage of the lighter flywheel is similar to the advantage obtained by removing the spare wheel and back seat, except that (pound for pound) removing rotating weight provides more benefit than removing dead weight.

 

Also, the flywheel helps the engine rev quicker. i.e. the pedal is "more touchy" in a way. Correct me if I'm wrong dan.

Peace

 

aside from the horsepower, the lighter flywheel would still benefit me in the quarter mile right?

 

I have a alluminum flywheel in my 95 max and my 98 I30, the gains are definatly noticable, but not huge, I personaly thing $475 for the gains is not worth it unless you are out of ideas for power improvements. But all in all I am happy with my Alluminum Flywheels.

 

I think in many of these discussions, it really depends on how you look at it.

If you're talking about power to the ground at the wheels, you probably will see gains. If you're talking about power at the crank, then there'll be no difference with certain modifications. If a more efficient drivetrain can reduce power loss from an avg of 20-25% to let's say 15%... you can effectively gain power at the wheels but the power at the crank is still the same.

That's what I was gonna say!

 

I look at it as a dynamometer looks at it. Lower vehicle weight, rotating or not, does not change the dynamometer reading.
