Testing Waters: $190 Unorthodox Crank Pulley Group Buy, thoughts?

[BITESIZE]

I'm in for the one you want bobafett....

For the record I want a UNDER DRIVEN SINGLE BELT CONVERSION. This means no AC, no PS - just an underdriven water pump and underdriven alternator.

[2oodoor]

meh, i know my crank pulley for sure has a harmonic balancer on it and im not gonna run without one, ive seen what happens to hondas that didnt have one.

I need to go look at mine again now, this sounds like like a argument brewing.
I know they are heavy and balanced, no insulator though. Running without that or a lighter pulley could at the very least start a different wear pattern on the mains eventually, whether that is a problem I dont know.
If you get the appropriate underdrive match pulley for the Alt. you don't loose the charging ability that much.

very nice work once again guaynabo89, that looks bootimus

[nswst8]

Going to sponsor another, Phil?

Not until I get under $500 out of pocket on the cam gears.

[bobafett]

Haha that would be cool if you wanted to sponsor this group buy too. I think if we get the prelude power guys involved again we might be able to pull it off.

Though honestly I doubt we would be able to pull off 30 buyers for a single belt conversion. We need to get a reasonably priced batch of those like guaynabo had made! Can you ask your guy what he would charge to make more of those in a single belt config?

[Vanilla Sky]

The problem you're going to have going with a single belt is that about half of us want an OEM setup. If Guaynabo can hook us up and get what he has made for around what has already been quoted (we'll say $200 for sake of argument), then maybe we should consider going with that shop. If we could get that kind of pricing with an order of 10 pulleys instead of 30, we'd have a hell of a better chance to get the GB sold out.

[bobafett]

100% agree... I know that an OEM belt setup is more likely to be successful, but I would rather modify the stock one than pay $200 for a gear that still needs more $ in mods to get slimmed down to single belt.

[guaynabo89]

why didnt you set up a group buy then....180 is a deal.

this was back in 2000. plus after he did it he said the crank pully was so much work he should have charged me 180 for the crank alone! lol



I know my stock pulley was just metal, I dint see ant type of dampening. it was one piece and I dont think it was fluid filled i know people have had problems with poor quality pulleys chewing up bearings so I had mine balanced up to 10,000rpm.

taking weight off the rotating assembly really helps. i also have an alum flywheel and my car revs almost motorcycle like.

[cygnus x-1]

I can absolutely confirm the following:

My '87 Prelude DX with carbed A18A1 had a solid steel crank pulley.
The '88 Accord carbed A20 engine I bought to rebuild also had a solid steel crank pulley.

Both of these have the smaller pulley nose on the crankshaft. Is it possible that the A20s with the larger pulley nose ('88-'89 A20A3) are the only ones with damped pulleys?

[Strugglebucket]

*sigh* i guess i'd be the only one who would want a stock diameter single belt pulley. i'll give up ac and ps, but not my alt voltage at idle.


oh, and i don't believe the stock pulley has any kind of fluid in it. but the fact that it's somewhat heavy means that by replacing it with a lighter piece you won't have as much damping. for example, you should hear how much louder the transmission is in nuetral when you switch to an aluminum flywheel.

[guaynabo89]

I get no noise from my tranny since I switched to an lum flywheel 9 years ago.

Altenators barely make any voltage at idle. they usually staet pulling good at around 2 grand

[Strugglebucket]

really? it's only in nuetral with the clutch engaged that i hear it. and it's not like a loud noise, just a slight mechanical noise that wasn't there with the stock flywheel. my point is just that more mass provides more damping. i don't know if an aluminum pulley on engine that has a lot of miles on it and hasn't been balanced is such a good idea.

with my alternator i get well over 14v at idle. car stereo is the one anti-performance mod that always gets me in trouble

[snoopyloopy]

i think i might be interested in underdriven pulley that includes all accessories.

[EricW]

Even though i already have a underdrive pulley with the A/c belt removed, I might be up for purchasing another one.

[Toohardtohandle]

I'm in over my head, but if there is a pulley that can improve my performance without losing a/c, p/s and won't effect my alternator...I'm in

I may be a dumb-ass, but I know what I want (lol)

[beerrrat]

i would just cut out the a/c lets keep the oem diameter, why would u want to lose ur power streeing?? and how u gonna run ur beat with an underdriven alt?

[Strugglebucket]

if you're really into performance you won't be "runnin' beat". and taking the power steering belt off frees up some horsepower. plus, then you can remove the pump and the lines and lose more weight. it just depends how far you lean towards going all out for performance.

[ghettogeddy]

im gonna be running 2 batts so under driven oem shouldn't be a prob for me

[bobafett]

what if you dont have room for ps or ac because there is a giant turbo and manifold in the way? :P

[Vanilla Sky]

Then you need to rework your turbo manifold :p.

To be honest, with as many differing opinions on this as there are, I'm sure that we're all better off contacting a machine shop if we ever decided to have one made, since we all want something different.

[MessyHonda]

yeah its not going to be easy...i like guaynabo89 one tho.

[beerrrat]

unless ur doin a swap these cars arn't really much performance wise anyway wtf.... fun to drive but it ain't gonna run 10's haha

[MessyHonda]

the fastest a20 was running 9s.

[beerrrat]

well i stand corrected. how muched he have uder the hood tho $12,000?

[bobafett]

and jason budd has been in the 10s for years. with an a20 prelude. but yes im sure they each have more than 12k into their performance mods. gotta pay as they say...

but yes i agree, if we can find a machine shop willing to make these for under $200 that would be the best answer overall IMO.

[2drSE-i]

jason budd is in the 9s with his EG shell a20. Johnny O was in the mid to low 10s in his accord hatch.
