Re: What spools a turbo faster: Light flywheel or Heavy flywheel
 

It's not a question of "what to buy" or "what will make my whip more unique" It was just a discussion between me and some friends and I wanted to see what some HMT guys had to say about it.

Thanks for the replies ;)

Re: What spools a turbo faster: Light flywheel or Heavy flywheel
 

I mean in the end its all about theories. We still don't know what will work from experience. What i suggest doing is buy a lightened flywheel and find out. Simple as that and you'll go down in history to be the nigga that found this ---- out :6. But if i were to guess i would say the heavier flywheel spools it first and the lightened flywheel makes more whp :y

Re: What spools a turbo faster: Light flywheel or Heavy flywheel
 

I have an 8lb in my crx, and I make boost on the launch limiter. wtf are you guys talkin about you cant spool a turbo without load? If you dont want to lose boost btwn shifts, dont let off the gas completely.

Re: What spools a turbo faster: Light flywheel or Heavy flywheel
 

I disagree with you one this in certain cases heavier is better, don't drift cars use heavier flywheels? companies make narrow band A/f guages dose that mean they are good...my real problem with light flywheels and crank pulleys is this...The crank is balanced from the factory and I assume the flywheel and crank pulley are too so changing one or both in my opinion would off set it, this can be proven with some of the guys killing oil pumps with the pulleys...I guess I don't have any hard proff but I would only assume this is true with the flywheel and may decrease engine life, I say if you do it get it rebalanced

Re: What spools a turbo faster: Light flywheel or Heavy flywheel
 

Usually brand new flywheels are balanced. Flywheel do not dampen crank wobble therefore it doesnt matter if it is aftermarket or not. Crank pulleys have the more important role when it comes to engine life.

Re: What spools a turbo faster: Light flywheel or Heavy flywheel
 

I wont ---- with aftermarket pulleys. I know too many ppl who have had their engine die of oil starvation bc of them.

Re: What spools a turbo faster: Light flywheel or Heavy flywheel
 

i dont think its because of oil starvation, its the lack of the harmonic balancer that throws the crank off balance and in turn will spin the rod/main bearings

Re: What spools a turbo faster: Light flywheel or Heavy flywheel
 

Yup.Break oil pump gears as well.I have a CTR pulley sitting here for my motor im building but Im scared of using it as it has no damper,harmonic rubber piece.I think the way to go might be to get a OE pulley milled down to remove the power steering and AC pulleys.

You can't spool a turbo without load. A load doesnt have to be towing a house, your engine always has *some* load.

well no ---- your going to build boost, hello 2-step? ::)
