my question is where do you get green serp. belts?

Gates HD belts have green backing

Mine are 2012. The leak was at the internal brazed joint under where the gil tail bolts. It was absolutely due to them not being flushed well. Came off a salt water boat. I got them for a fair price and once I spoke with hardin about how they could possibly have welded that they told me that part is not welded. It is brazed. Easy enough. I sand blasted it and cleaned it well. Then brazed with a ssf-6 rod. Put 2 plugs in he lower outlets and a valve stem on a plug in the top. Shot it up to 150 psi of shop air. Sat it in a tub of soapy water and watched for about 5 mins. No bubbles. Next day before I removed the plugs, I read the pressure and it was still right at 149-150.

Has anyone run these in a bigger(540 650 hp ish) NA setup? I have gils and was considering buying a pair of E tops but if these will do just as well(or really close) I can save quite a bit of money.

Looking at them it doesn't look like the runner on E-Tops are all that much longer. If you want I can measure mine E-Top runners. I just happen to have one off.

The green belts are gates and there heavy duty version they seam to hold up better than the regular ones
