Well, if it's the only full set available, then it actually is the lightest. Not an overstatement at all.



...it's also the heaviest.

A set is a combination of individual elements. Idlers are nice and I will buy them separatly (thanks Raceseng for providing such an option). GFB's 3-pulley set + 2 Raceseng idler is the lightest set in the market so far.

However, if I didn't have the GFB set already, I'd definetely buy the full set Raceseng - the difference in weight in negligible and Raceseng looks just so much better!

Yeah, I plan on having a mismatched set, but basing it off the Raceseng kit. I believe Tomioka makes the lightest alternator pulley.

Here's a post from a while back: http://www.ft86club.com/forums/showp...&postcount=133

You can pretty much be guaranteed those numbers aren't accurate, though. When speaking in pounds, if it ain't at least 3 digits behind the decimal, it ain't accurate.

forgive the noobie post but im still learning everyday...

i know these are serious weight reduction, but how do they affect power? like will i make more HP if the pulleys are lighter?

also, how will these work with FI? like will the huge power bump cause issues?

Your engine will still produce the same amount of power as before, but it won't be spending so much power simply making the pulleys spin. So more power will get to your tires. So it's not about making more power, it's about not wasting what you have.

Stupid question here. I've been looking in to pulleys (specifically crank) for a few days now; HOWEVER, due to my wife not being able to drive stick, I've got an auto. I can't seem to find an answer to the question whether these will easily still bolt up with auto and whether it would even make a difference.

Found a thread on nasioc where it was basically stated pulleys aren't worthwhile on autos due to how they work. I won't lie. It was all above my head as I'm not much of a gearhead.

These are STX legal. Any/all accessory pullies can be swaped.

@Raceseng do you offer the idle pullies by themselves? I already have other pullies that im satisfied with.

HI,

I also have GFB set already, so I plan to do the same thing like you

(GFB's 3-pulley set + 2 Raceseng idler )

Is there any issue to do the mismatch?

I just wondering there has some balance design in it or not.

Thanks a lot.

Working on the groupbuy soon. We are scrambling to get all of our products loaded to the website.

Not to mention, there are 5 other products in design, prototyping and manufacturing stages... AHHHHHHH!
