No link to them but apparently i know how to google so here's some info: RE-Zelse: SpeedSource Pulleys Review

Slidin8

i did google, i seen it was a review and skipped over it and went through the speedsource site

i had no idea they were a race team since i do not follow US motorsport

no need to be a sarcastic about it bro

thanks for the link

I mean, some performance would be nice. If I wanted them just for looks I would just powdercoat my stock pulleys ha

Well......unfortunately their "new" website isn't up yet, but I've been running these for about 5-6 years now with no issues.

Coming Soon. The New Unorthodox Racing Website...

Pulleys really are for bling only.

You can trust Ric Shaw. He is a racer in Australia and while he doesn't have much of a name in the states (especially in the RX8 world), he has quite a good reputation down there.
Most dyno results, for pulleys, are useless. It is my belief that you will only get 1 or 2 hp out of them. That is within the margin of error or the change in conditions between the two dyno runs. The main purpose is to slow down the rotation of the water pump and keep the coolant from cavitation while at high rpm's.

sorry for hijacking your thread damn...

slidin8.. best way to get speedsource pullies is to pm someone who races their car and is a mazdaspeed racing member or whatever its called. They can order the part for you and you pay them for it. The speedsource pullies deletes your AC though.

there was a partout of a racecar and the pullies got snatched within 2 days or so.

I may just get the supernow alternator pulley haha, its so awesome

Slidin8

i want to get the whole lot but im unsure on how to get the correct belts since the pulleys are different size.

i really like the purple, i may get my intake powdercoated that colour if i do get those pulleys and run with that for an engine bay theme

mazda876

so when you put these pulleys on the mazda rx8 whats the hp increase??

RIC SHAW

there could be a small increase as most other manufactures claim. but i can not say.
The benefit is the slowing of the water pump and alternator, this prolongs life and helps stop pump cavitation.better cooling when driven hard.
aslo look good. they are lighter so will spin up faster, like a light fly wheel.
i have them on my SP RX8 race car.

Thread revive! Holy cow that's a good price on Japan Parts! Do I have to change the belts?

Slidin8

From my understanding, oem belts work fine

Carbon8

iTrader: (4)

Nope, you need. 33.5" belt OE is 32.

Slidin8

I stand corrected. Thanks Carbon8. I was told by a vendor on another forum that oem belts work thats all

Danmn858

iTrader: (10)

Lol damn you guys are up late. Was not even expecting a response. Where do I go about getting such a belt?

Slidin8

Lol its 630pm here in NZ mate

Carbon8

Went to the drive in tonight.

And yeah me and Charles just dealt with that issue about 2 weeks ago. Had to special order a gates 33.5" but it worked out great. Also recommend going with a stiffy bar for tension as my OE adjustment is maxed out and still not up to backlash spec but it functions properly so I let it be for now

Blame the water pump pully it's substantially larger, crank and alt are OE size.

Yeah I'm in Singapore right now so it's like 230pm here.
what is a stiffy bar? and how much did that belt cost you?

Carbon8

iTrader: (4)

Stiffy bar connects the alt to the strut tower and adjusts tension. Used for REW and 20B swaps, larger range of adjustment. I have no clue on price, maybe 100 bucks

Gates racing belts are 35 bucks, or cheapie auto parts ones are about 12 bucks

You need to go to Bangkok for a "Stiffy Bar"!!!

Ill post pics of mine tomorrow. I ordered from the same site. About 4 week delivery time FYI.

Is that the Ingalls stiffy we're talking about?
If so, 100 bucks is a steal!
Good price.

Carbon8

iTrader: (4)

IDK didn't look at prices, 100 was wishful thinking. If its more its more.

Heres mine, I opted for the titanium (IMO Grey) as the other colors would have looks out of place in my bay.

I was literally JUST in Bankok a few days ago
Was there for two weeks

Thanks for all the info. Whats the point of the bar on our cars? Just because the pulley acts different?

Carbon8

iTrader: (4)

The OE adjustment is limited, going with the stiffy bar is needed when getting different size pulleys in order to account for a larger belt and achieve the tension spec. Just allows a much wider range.
