Underdrive pully..yes.. or no?

Should i change over my power steering pump and belt tentioner so i can put my under drive pully on? or should i keep it the same as the 91? and just used the stock pully?

I am not going to make any suggestions about how to go about underdriving your car as that is your decision. But if anyone tries to claim an underdrive pulley screwed up their car then they are completely full of it and are just spreading crap. THere is absolutely ZERO proof that the 6G72 needs a harmonic balancer and there are several people making big power running underdive/lightweight crank pulleys with near or over 30k on then with no issues. Other people had an oiling issue and were looking for something to blame their engine failure one.

not worth the trouble IMO.

It's not much trouble.. I mean the motor is sitting out of the car right now.. and I have the belts and underdrive pully (for the 92) and i have the p/s pump already.. so I dont need anything.

What trouble? Its a 15 minute job for a decent cheap power gain.

The Spyder has had an underdrive pulley on it for a decade. Zero problems.

ill admit, i may have been swayed by engine failure horror stories.

This is the link I always post when somebody asks.

Personally, I have to admit my opinion has flip flopped on the topic over hte years. As far as I know, Stealthee is correct in that nobody with our engine can attribute an engine failure to it. However, I also can see the reasoning behind both sides of hte argument. So best I can say is make up your own mind.

I would rather just use a lightweight pulley, instead of an actual underdrive one... I worry about the annoyance with my stereo and stuff.

Lightweight yes, underdrive why?

jason_bet · #11 11-13-2006, 01:17 PM
