I like it!!!!

How/when can I get a few of them there pulleys?

 

PM Latemodel21 and inquire.

 

I would like to see a water pump pulley to add to the collection as well. new ribbed idler and bracket will be on the way soon.

 

Here is a pic of the Belt Wrap Kit configured for the larger crank pulley shown on an SRT6 with a 185 crank pulley (and a stock SC pulley). There is plenty of wrap eliminating belt slip at the SC . Also, the larger Alternator pulley slows it down to a reasonable speed (larger crank pulleys make the alternator spin up to 19% faster than stock) and eliminates slip there as well. This pic shows a proto alternator pulley, but I am currently having similar production versions of this alternator pulley made for this application (that, like all the other pulleys in the kit, will have a hard-black anodize coating on the belt surface).

Unlike the kit for the 61-65 mm SC pulley which was able to use the original serpentine belt, this kit requires that a new belt (k081177 ) be used.

Cheers,
Chris

 

I installed another set on a friends car and added the bracket and pulley for mine. This belt wrap kit is very nice.

I've had the kit installed for about two months now and love it. I'll post a pic once the engine bay is cleaned up a bit.

 

Has anyone done a before/after dyno run on the reduced rpm alternator pulley along with the better contact patch on a 65mm supercharger pulley?

 

Why would you REDUCE the alternator pulley size ?
That would make it spin faster, requiring more power to do so and imposing extra strain on it.

 

thanks for pointing out my inadvertent error. now edited.

 

Of course he was referring to UNDER-DRIVING the alternator ... but good of you to catch that



While I would welcome any before/after dynos (particularly any that suggested a big gain ).. I suspect the difference would only be large in the case of a car that was slipping consistently before. Just as good as a dyno run in this case would be to compare typical boost (boost profiles under full acceleration) before and after adding the kit.

The difference to the alternator is more likely to be reflected in how fast the motor spins up (by changing the speed that this "flywheel" spins relative to engine speed) and how long the alternator lives (bearing life, etc.) neither of which will be reflected on the dyno.

hope that helps,
Chris

P.S. Any who have data they want to share .... please share

 

Hello, Chris,

I sent you pm, a week ago but you did not reply. Maybe there is some issue with your inbox..

Please send me pm. i want your belt wrap

 

I'm not sure that "full" qualifies as an issue, but I'll use it as an excuse.

I am trying to avoid selling partial kits as it leaves me with the rest of the kit . And, shipping to Europe doesn't make it any more tempting. But let me consider it a bit and I will send you an Email.

Cheers,
Chris

 

Haha
Aniway, the shipping to Europe will be less than 50$ (just receive S/C pulley from US)
So if you want to offer me something, feel free to send me message.

Best regards
