Belt Wrap Kit for Supercharged M113 motors
Buyer silence on a new mod is never a good thing. Generally people post up impressions of a new buy while still in the box.
I'm interested in this, but only when proven to not carry any baggage.

I put my belt wrap kit on last week and just put the motor back in yesterday. Also added the smaller super charger pulley. I love just looking at it!

The reason you made 22hp more is because they used STD correction instead of SAE. Not a good comparison. STD corrects to a lower temp and makes 5% more.
Bottom line, with belt slip you loose boost and a little boost can easilly be 20-30 hp loss. Nice to see peopel starting to post thier feedback and dynos to give us ideas. It is common knowledge, that all our belts slip and the reason we get so much belt wear and nasty black dust all over our crank, sc and idler pulleys.
Below is a quote from GM Hightech magazine that explains STD
"STD Correction
STD, or standard correction, represents one of the oldest correction factors used by the Society of Automotive Engineers (SAE). STD is also known as J607 and it uses standard conditions of 60-degrees F, 29.92inHg and 0-percent humidity. For you engine dyno enthusiasts, these factors should look familiar, as STD (J607) is one of the most popular correction factors available and used almost exclusively by NASCAR teams to compare results from chassis dyno testing to results from the engine dyno. STD is also one of the most stable correction factors, in that it has not been changed for many years and the ideal factors remain consistent."
This is as close as I could get to my BW kit installed. Need to try a side angle for the next picture.

Check out the video of the stock idler below, before we installed the 3 kits for him.

The picture in my post above, was before the car was started or belts aligned. This car made 518 RWHP with SC pulley, belt wrap, headers and tune only! That is impressive and clutch engagment was extremely smooth.
