Main girdle how many of you run these? just wondering at what horsepower you guys think that a girdle will actually help? im doing a 408 with a thumper series. just wondering if this may be helpful in my build.

On my camaro stroker motor build from EXOTI PERFORMANCE PLUS.com I had them install one and can make over 700RWHP.I would not feel good about this unless I had one.It is cheap insurance.
Please note the LS base stuff is not like the ford 302 blocks. I have yet to see anyone split a block. Now if your running 1500-2000rwhp then yes but 700rwhp is a walk in the park for the LS based stuff.

Mike or Steve, girdles on those ERL blocks? Or just pinned caps like the normal poeple?

The Casper engine had a girdle and showed bearing life that was incredible, but it did not run much. 6.86 @205 with about 1900hp
Mike Brown used a LS1 block without girdle and showed reasonable bearing life for his estimated 1400 flywheel hp, but the caps did move a bit.
Steve Turley used a LS2 block with a girdle, all his bearings showed good except the rear of the thrust. He was a touch higher power than Mike, probably 1500-1600 based on his 9XX to the tire and 7.79 in Memphis.
After this coming summer you should start to see a pattern of what level the main bearings start to show problems. Can't wait to take apart some new stuff to see how its holding up to the incredible power produced.

I'm betting his thrust bearing is more a result of the forced staging habits we have for turbo cars. I'd be curious to see what Tom's looks like after the burndown.
if they had actually put some boost to it on the dyno it would have pegged it like paul did. Steve was running in the mid 180's at 3400, it's probably a little higher than 1600.

He was suposed to be the last car on the dyno and just wanted to put down enough to get the win. But an LSX block guy asked if he could sneak in. Hmmmm 
With the amount of passes on the Camaro at that power level. We couldn't be happier with the way the bearings looked. It does run pinned caps with a girdle.
I've never ran a girdle on my motors and think we have gotten really good data. I think were all in agreement that pinning the caps is a good idea.

anyone have pics of pinning the caps? I hadnt heard of it till recently. I'm building my iron 408 now and might consider doing it. Also is everyone running the stock caps or billet?
