GI; 2.5L Light Weight Crank Pulley

[aahtxb]

start with the 2.5!!!!!!!!!

I personally don't have any experience, but IIRC, i've heard that some underdrive pullies need modification of the oil pump housing do to improper fit. I would make sure that's addressed.

[ya_whatever]

On the site the 2.2L ones say they don't need modifying.. Unless I was reading the site wrong, might be I just have had stars in my eyes LOL..

I think what was said about the built balanced engines versus stock shows how a torsional vibration damper named differently actually gives up a lot of misconceptions of what it's for.. IT HAS NOTHING TO DO WITH BALANCE!!!! It has to do with the frequency, harmonics of vibration and degree of twisting of the crank. Simply if you want to see what it does take your index finger from one hand grab on to it with the other had and twist your find notice the elastic skin kinda holds back.. Thats what the rubber does. Best bet don't worry about it and those that want it maybe can spend their own money on properly designing a damper. Or offer several different fluid dampers of different frequency's that'll bolt on.

I'm in for one as long as I don't need to balance anything!

Just let me know.

I used to do alot of the prototyping for Rafi back when RR was bringing out new products.

Still have #1 of the RR STS and RR stabilizer bushings on the wife's car

Thats awesome!!!

Well the 2.2L pulley is almost done, and then we'll start on this pulley.

I hate to say it but I am a vendor for OBX, so if anyone wanted one of those pulleys let me know.

so can we look foward to one with a balancer?

[Md323]

oooh boy, here we go again!

It will not have one

[MakatoMotors]

<< dissapointed
was really looking foward to a 2.5 pulley with balancer

[riithunder916]

But doesn't the engine need to be balanced? Does the stock pully come with a balencer?


Mike

[TravisWilliams_GT]

I'd get one because eventually, all the OE ones WILL separate at the outer ring.


And the wife uses an OE one.

[riithunder916]

yes the oe will seperate, and that pisses me off, but do you need the balancer? if not then I'm all in and still in, if so, then I'd be hard pressed to buy one, I'd just find another OE ones.

[ya_whatever]

If you look at the OE ones the drilled out holes are what provide the balance. You know I think for most of us the need to stop the crank from twisting by letting the weight on the pulley lag is minimal. If there was a greater need for it those guys would never get that 1000 HP 2.5 on the stock crank, it'd just twist itself to crap.

[MakatoMotors]

but dont we already have undrive pulleys ??? wat the point of another one? y this over the ebay ones or rr ones. idk maybe im confused
