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.

I havent heard of anyone going any higher with the stock oiling system, just make sure you have enough oil in the pan. With dry sump, the rod bolts are the limit.

going to convert over to dry sump this winter.......the wet sump can't carry enough oil capacity to sustain 7000RPM+

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).

I have been a touch over 8000 many times. I am running a ported and shimmed Melling pump, though. I see about 85 to 90 psi at rpm. No probs so far.

90PSI? Damn!

Whats the deal with the melling pump? Just plain badass or what?

Order 66

The best is the QTP two piece timing cover and there HV pump. Buddy gain 15 more psi over the melling pump on his 383.

I saw that pump as was very interested. Do you have to use there timing cover with that pump?

LOnSLO

iTrader: (15)

Uhhhh, that is the Melling pump.

Also, you just have to do a little clearancing on the factory cover for the bigger pump to fir. Took two seconds.

That's what they mike Die Grinders for right. Cool, sounds like that's the way I'll go then. Hey LoNSlo, sending you a pm now.

The right way to spin to 8000 or 9000 would be a 5 stage dry sump, but who can afford that

DAPSUPRSLO

iTrader: (14)

I hear ya on that. I asked Erik about it and he said I'd be looking at a $2500 on the low side. That made that decision real easy, WET SUMP FOR ME. My buddy pieced one together from Ebay for his sb2 project but took him forever and he's still got quite a few dollars rapped up in it.

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.

I've heard of this, but have never seen it. Where does the pressurized oil re-enter the block?

DAPSUPRSLO

iTrader: (14)

About what kind of cost does something like this run? Just curious, thanks.

iTrader: (6)

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.......

Bryan@LME

iTrader: (4)

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,

Wow, that's just a little bit more competative then the dry sump alternative. Thanks.
