Gates green stripe blower belt

[Detroitboy]

During research on Gates belts for our blowers I happened across a listing for gates green stripe belts. Has anyone heard of these? Are they any better than the green gates belts #100579 at Amazon for under $40?

Thinking they are the same belt. I run the standard black belts. The green belts can snap being they have less give and they don't grip any better

I use these belts, they are made for supercharger use, they hold up well and I turn my superchargers pretty hard, used same one on my whipples as well when I was running them.

That size belt fits with using the AAD Idler pulley in center mounting hole with +10 lower with that 2.74 Satera Griptech prepped upper with 1/2” thick FI Insulator Spacers. Blower making 25.5 psi of boost very little belt dust.
Also fits +10 lower stock upper and no spacers or idler pulley.

Yes, 25.38 to be exact with my hand ported 2.7 snout and 105 TB, has my custom billet 2.7 inlet plate with oiled bearing, the thing is singing but staying happy so far!! Have to try the SDG snout and NW 108 TB someday.

Man that’s moving air! Wonder what mine makes no (just a dinky 2.4) pretty sure I’m maxing out the stock map sensors

Yes, seeing almost 2300 Aircharge and 2.82 PR
What pulley combo on you 2.4?

Nice!!
My guesstimate of boost on stock displacement, stock or RE cam, stock exhaust including cats, 20-21 psi 1900-1950 aircharge.
Yes, most likely your 2 Bar map sensors are maxed out around 18-19 or less. (2 bar is 14.7x=29.4 - 14.7 = 14.7 psi, that’s why RE 2.7 blowers where equipped with three bar sensors which read to about 30 psi of boost or so.

I do have long tubes though, 2” primaries

Probably still out of the sensors ranges.
I suggest replace your map sensors, all four of them with the 3 bar units and have them remapped in your tune, it’s just changing numbers. I may have a set around I could sell you for $200 for the four of them +$10 shipping. Let me know if you want them and I’ll look for them.

So will that belt fit with a stock idler and 3.10 upper pulley?

No idea with any certainty. How I get close for a belt size as I put a string around all the pulleys and then put the tensioner in about the middle of it travel and match the string up, put a mark on it and then measure its length and see what belts are available in that size

 

[Unholy707]

Just get an adjustable idler

The correct number for the Dayco belt same size as stock is Dayco Racing 5100580S. I ordered it from Summit. I think it was $46

The 100 at front of number means it is a 10 rib. 579-580 would be a stock belt. Find a belt between 575-578 for a 3.10 pulley but I also wouldn't even bother with a 3.10 pulley. If you are changing the pulley you should go smaller because once you change it, you will again.
