Kinda cool. Does it really produce that HP though??

looks pretty cool.. probably only good as an engine dress up peice though.. not sure how functional it would be...

yea figured it is prally more cosmetic but hes not like creates 10 hp bs so maybe its legit? idk much about engines and all the technology but a guess?

It probably frees up some HP, but I doubt 10

Looks good, but is it style over function?

He's only claiming 2-3hp....that'd be right for a 10% underdrive pulley. Looks trick, I reckon.

pretty sweet, not real anxious to play with my belts though.

Looks very similar to the one's that Higgi produced for the Rx-7. I'll post a pic of my old Rx-7's engine bay if anyone if curious as to how it looks on the engine.

no you read it wrong i didnt say it claimed 10hp... i said its NOT like he claimed 10hp bs everyone tries and pulls... he actually states 2-3hp...so thats more realistic

I'll take "Pics of old rotary engines" for $500, please Alex.... :D

*buzzer sounds*

DAILY DOUBLE!

Today it's our video daily double. Take a look at the following pic.

Nice......Ahhh, distributors....those were the days....!

Thanks,

Would it be much lighter????????

hey even if the dont work... there always still cute! ;) :p

too bad i just can't afford to underdrive my alternator

It was lighter on the Rx-7. I don't know how much the one weighs on the Rx-8, so I can't comment.

Damn, I miss my first gen Rx-7. :(

I don't really want to underdrive the alternator on a car that was a piss poor battery as it is.

Looks damn cool, though.

OK, I went ahead and bought it. My wife's limited me to the occasional $50 purchase for the car.... until we get the insurance check for her car. Then I'm allowed to go crazy.

Just looking at it, it's very nicely machined. Fits in the palm of my hand. I'll do a size/weight comparison this weekend. He's in Florida, so it was a really quick turn around. Not sure if I'm going to install, I'm still toying with the idea of using it as a paper weight at work. LOL

On a side note, he did send a few kitkat mini's with it. Guess he wanted to sweeten the deal... sorry, couldn't resist.

rotary shaped alternator pulley

weight: 107 grams -OR- 3.75 ounces
diameter: 2.5 (ish) inches

I say 2.5(ish) because I'm measuing out to the lip, not the surface where the belt would be making contact with the pulley. I'll guestimate that the contact surface diameter is 2 3/8.


**Edit***
Just ran outside the width of the OEM alternator pulley is right around 2.25 inches, lip to lip. Subtract the width of the belt (times 2) and that's the diameter of the contact surface.

So the rotary pulley is slightly larger. Hrmm, what effect would this have? Also, anyone know the weight of the stock alternator pulley? cortc?
