I have the best RINGs!!!!!

[Turbofreak]

I will have the most awesome rings ever in my Turbododge!!!

I am having a custom set of Total seal Gapless rings made in their Chrome-Steel top ring with their ductile moly second and stainless 3 piece oil ring set for our standard
1.5/1.5/4 mm ring package on our engines

cost is about 4 times what a normal ring set goes for...

I spoke to Kevin there and he was very helpful and informative...

I was just afraid of putting the regular Speed pro rings in the hole again, knowing that theay are just cast cheap rings....

Sealed power used to make file to fit rings for our engines, but they have been out of production for over 6 years now... and their aren't any in any warehouse... believe me.. I checked...

I know that these TOTAL SEAL rings will hold up to what I need...

Kevin said they are the only rings that will take the high horsepower/ heat-stress loads of high Boost/ Nitrous together on a small bore...

Also I discussed with Kevin that I was cautious to use a gapped ring (normal-style) because of the possibility of all the extra crankcase pressure that will/could build up with all the blowby that will make it past the rings....

I wanted to run a vacuum pump to pull crankcase pressure out, but I know from experience that you can't run very much vacuum in the crankcase of a wet sump engine before the oil doesn't want to return to the oil pan because the vacuum pulling on the valvecover wants to pull all the oil to the top of the engine....

You can't pull much more than a few inches of vacuum on a wet sump engine before encountering oil return problems....

So... I decided that I wanted a gapless-style ring to counter this blowby-crankcase pressure build up ... Yes, I will still be running a blowby-catchcan-oil seperator off of my valvecover, but no... not a vacuum pump...

Sweet dude. I wanted to buy gapless rings when my engine was out in February but couldn't afford it plus had to strip my block for the special ring hone. Next time will do it. Let us know how it works out!

[Turbofreak]

I hope to take some pics and of the part numbers so it will be easier for everyone to have gapless in the future...


BTW- did you ever get a part number for the Kevlar REar Band and who did you get it from- you and russ right??

Sonnax didn't list it, but they gave me part numbers on the h-strut and governor fix kit...

I spoke to a guy at sonnax, and he didn't know anything about a heavy duty rear band....


Thanks!

P.S.- any news on the gear with the roller thrust washer???
THANKS AGAIN!!

hEY, I will send it out monday, cheers!

great

Why would you want to run a vacuum pump on a boosted engine?

[Turbofreak]

You want to reduce/eliminate as much crankcase pressure as possible out of the engine....

Crankcase pressure is caused by air-pressure leakage from pistons/rings, poor valve seal against the seat, etc...

This is what causes blowby...

Wear of rings/ cylinder walls/ pistons....

If you get too much cylinder pressure built up in the crankcase, it causes ring flutter, because rings are designed with a certain amount of twist in them to load them against cylinder pressure... and when the ring sees cylider pressure from combustion, and it sees crankcase pressure from blowby... it is having to fight both ways....

Also, look at it like this.... if the piston has pressure on it's underside, it is that much harder to push down, therefore, the horsepower made by combustion is having to fight the crankcase pressure on the back side of the pistons...

You can eliminate/greatly reduce crankcase pressure/blowby pressure by running a very good crankcase breathing/catchcan system, such as one that MOROSO sells...

It will keep crankcase pressures at a minimum which will make more horsepower... even with excessive blowby, if you can vent it out of the block, you can pick up horsepower!!!

Does that make any sense to you??

Ask more questions and I will try to explain further if needed...

Thanks!
