Honestly, I have no idea lmao Enough boost to hit my power level target. With the cam and port work I've done so far, I figure these probably add roughly 60HP to the previous engine iteration as just simple bolt ons, so I estimate this engine should be at 300-310whp at 15psi. So maybe roughly in the area of 20-22 psi to hit my target?How much boost are you planning to send through it? Think O-ringing is absolutely necessary?
I lightly ported mine and smoothed the transition at the pump exit. I was getting similar hot pressure numbers, last engine iteration ran around 12-15 hot with 5W40 Rotella T6, until I installed the oil cooler. I saw significant pressure increases at both idle and cruise.No doubt, don't let the Corona get you......... Have you upgraded the oil pump? Self ported or even Bad Guys offers a new high volume oil pump. Been thinking about getting one of theirs for the ZC. When its hot and idling, it gets a little low for my liking. Anything below 10 at hot idle frightens me.
The Isky Cams Groove-o-Matic oringing tool. Works great, if only they fucking made one for smaller than 3" bores lol. 3 1/8" is as small as they go, I've investigated lmao. This tool would be slick if it would have worked in my bore, it would be in my checkout cart right now lol.
Hmm.... damn it Slo! Lmao, don't even get me thinking. It is a good idea though.but...... what if you could use a piston to center a cutter and make your own?
I mean, in theory it shouldn't be too hard right? drill a hole in the center of a piston (possibly wrap the piston in painters tape to take up the space) and use a hole saw to gentle nibble away at the surface creating a groove..... could do it by hand and take your time
“We’ve really been focusing on the MLX gaskets, because of all of the engines that we make gaskets for, everything is a high-performance application,” says Cometic’s Kevyn Kistner. “With the Stopper gasket, the center layer is folded over back onto itself — this creates an additional stack-up right at the bore, and once you tighten everything down, it focuses more clamp-load from the bolts to the bore. That’s really where the pressure is.”
Cometic has put this design into use in their Subaru, GM LS and conventional small-block Chevrolet, and late-model Hemi engine offerings, among others.
“For anyone out there making serious horsepower, we have an application of that Stopper design,” says Kistner. “We’ve had great results with this, and guys are holding big horsepower with them. Years ago, you had to go with copper and O-ring on everything with big power numbers, but we’ve finally been able to create a product line that totally antiques that old setup.”
