even in the super fruitcake miata community, this is known and understood:

Flyin' Miata : Engine/Drivetrain : Internals : ATI Damper pulley kit

"We`ve found that really high horsepower Miatas - over 280 hp - have been overwhelming the stock harmonic damper. This can crack the gears on the oil pump as well as damage the bearings from the hammering. We worked with ATI to develop this replacement damper to solve the problem. You can read more about what harmonic dampers do here.

This unit replaces the stock damper with what is essentially two in one. The result is not only a safer engine, but one that runs more smoothly all the time thanks to the improved vibration absorption. This is exactly the opposite of billet "underdrive pulleys" that remove the stock damper. We`ve seen those destroy a typical turbo Miata engine in a couple of thousand miles."

ahem. carry on your useless non-engineering level of existence. class dismissed.

lol, i love you mike.

..Also, those yellow pulley's above are made my NAPREC of Japan, its a $1500.00 set.

Be a baller.

Says for s14-s15 SR only.

will just the crank pulley do anything..as of freeing hp? or do we have to use all the pulleys together?

I had the ur lite weight pulley and fidanza flywheel on my sr and I never had a problem. It made a big difference in revs. I loved it.

How long did you run it for? Also did you have an oil pressure gauge? If so what was your pressure before and after running the pulley for awhile? What happened to your SR that is making you sell the pulley?

I ran it like that for over a year with no problems. Yes I had a gauge but I have forgot what the oil pressure was since its been months since I have drove the car. I sold the sr to fund my ls2 swap. I WANT TQ!
