I was curious as to how you guys keep your crankcase pressures down low. Do you guys use a catch can with filters, vacuum pumps, tie in the exhaust to pull vacuum.... I know Tony at T1 runs a catch can box with 6 freaking lines coming out of his box, to me that is just to much so I was looking for a simpler design.

 

For our drag car and pretty much all other high HP cars we just ran 2 -8 lines to a vented catch can. Havent had any issues. We havent done any testing with a vacuum pump or with the exhaust vacuum setup yet.

 

Would be nice for you guys to release the Dry sump....

This is something I thought "could" make more power is a some sort of Vacum pump with as much crank case pressure these motors produce. V8 Guys have had lots of luck with vacum pumps, on a SBC 441CI I saw on a Engine Dyno 35-40hp gains from just a Vacum pump, This was on a 14:1 motor. Not sure how it would perform with a 120CI motor...But under high boost ( Compressions of 25:1+)

 

+1 im getting crazy oil pressure with my built motor havnt tried the vented catch can yet!!

i have a non vented catch can laying around the house can i just drill and tap a air filter on the greddy catch can??

 

were the fittings welded on and if so can you post up some pics.
thanks

 

i think they just tapped the existing holes in the rocker cover to allow bigger fittings.

 

NewCalEvo, you are correct. Here is the catch can we use, I use it on my personal car and a few other guys here use it also.

You tap the hole next to the Cam sensor by taking out the little tube that would normally recirculate back into the intake with a -8 AN fitting. You then take out the PCV valve and tap that hole with another -8 AN fitting. Run both those lines to a breather can "IMO better then a catch can" like this one posted below.



AMS has built a couple cars with a Dry Sump oiling system "vacuum pump as referenced above"but still not has released it to the public. Even if they would just release the gear drive system and oil pan the rest could be bough separately. HKS makes a Dry Sump system but its like pulling teeth to try and find somebody that will sell it.

 

See now i never knew you had that. Another good option. Putting in a order now..haha..

deleted sorry.

 

As far as the HKS dry sump goes, I believe that they only have a scavenge setup. All it does is suck oil from the pan and send it to a storage tank where the stock oil pump draws from. Thus still using the stock oil pump to create the pressure. So in turn it is not a true dry sump. The "dry sump" that we are designing is a true one. It uses the pump to scavenge and produce the pressure for the engine. This is a pretty complex piece and we have been doing some extensive testing before going into production with it. After all this kit is the heart of a potentially expensive motor. In the next week or so I will be releasing the pricing. We are still finalizing the bracket and creating a tensioner to keep the belt taught.

 

That catch can is sweet looking, and very compact from the looks of it. I may have to put in an order for one.

 

Have you guys done any testing with having the exhaust pull vacuum from the engine during high rpm runs? I would think the amount of exhaust flowing during high boost and high rpm's would be more the enough to pull vacuum from the engine.

 

Ive been thinking about trying it this year. The only think I dont like the idea of is spraying the track down with oil vapors.. then again though the V8 guys seem to all be doing it. If I do it I will post up the results.
