Reducing Turbo-Lag w/Flywheels

[CowPimp]

Has anyone here used a lightweight aluminum flywheel or some other form of performance flywheel on their TurboDSM? Does it help the turbo spool sooner? What kind of improvement in 1/4 times?

Read those two and see if that answers your questions. If it doesn't, post back here.

A lighter aluminum flywheel will actually cause the turbo to spool slower than the stock one. The big misconception is that if you get into rpm quicker, you will spool quicker. This is not neccessarily a true statement. Turbochargers are load dependant, not rpm dependant. The heavier flywheel will actually load the engine/turbo up more and cause it to go into boost quicker. Want to experiment this for yourself? Get on your car on a flat road, and see how much boost it builds. Now, floor it uphill, and you may notice the car build more boost and sooner. Obviously the car will feel faster on flat ground, but that's simply because you are fighting acceleration with gravity when going uphill. It's the same reason the car won't build as much boost in 1st gear as it does in 3rd gear. It's load, not rpm. I hope this answers your question.

yeah thats right buddy had a grand national, the auto always put load on it so he would just sit there and build up boost then launch the mf'er
