High RPM Big Motor Guys, What Oiling System?
Hey guys, I'm interested in what rpm alot of you are spinning your motors to. What rpm and what kind of oiling system are you using (dry sump/wet sump). Also, what kind of motor (bore x stroke, compression, rod length, etc.). Any kind of information you can provide would be great. Thanks.
Gotta a solid roller 434 in the works right now and just want to see what some of you guys are doing out there.

Ok, I'll start then. 434, 6.125 callies compstar rods, huge dish weisco turbo pistons to offset 37cc chambers of c5-r heads, callies racemaster crank, 4.00"stroke x 4.155" bore, 11.75 to 1. Don't plan to spin past 7500 at the advice of HPE on the limits of wet sump within the ls1 block (darton wet sleeved block).
Just curious as it seems like quite a few spin faster then this with a wet sump. Thanks.

Cool, this is what I was getting at. Actually Tosto is going past this with a wet sump in his 422. I was curious to see if any others were. I was advised that 8000rpm and a wetsump will make for a "short lifter". Doesn't mean it can't be done, just curious to see if anyone else is doing it (7500+ with wetsump).

At LME, if we are not going dry sump we modify the stock oiling system. We do so, in a way that eliminates aprox. six 90 deg. turns that the oil has to make. The system uses the stock pump with an external filter and pressure regulator. We have this set up on several of our race engines seeing 8-9000 rpm consistantly. On freshen ups the brgs. look real nice.

do you have any pictures of how you do this?
I'm THINKING you come out the front port, run to your filters/oil cooler/etc., then go in where the oil pressure sensor is but thats just a guess.......

The oil re enters the block at the oil plug location above the oil filter. The stock filter housing is pluged and you use a remote filter. Im my opinion this system makes the block as close to priority main oiling as you can get with the factory block.
Sorry i do not have any pics. The price with the remote filter housing, pressure regulator, fittings and machine work is $700.
Thanks,
