Lots of new parts on the 505 for this round of testing. Dry sump system is main focus with custom drive parts and mounts. Jesel sent me some 1.85 ratio rocker arms so I'll be doing some ratio testing. I'm using a cam from Jones in this motor. This is the first time I've worked with Mike Jones over there since I've always worked with Comp in the past. I also have a full ignition system that MSD sent for testing. 7AL2+ with a big honking HVC coil. Guess we'll see how it all performs here shortly.

Close up of the ignition plate I built for the back of the motor. This makes it more self contained so we don't have to rewire the dyno cell. Thanks to the guys at MSD for the parts and tech support.

My son is 11 now so he is starting to help out with building motors. By the time he is in high school he should be a decent mechanic.

that's cool that your son is interested- mine couldn't care less. good luck with that motor, i hope you blow it up (the dyno)!

Is this a Flat cam, or a roller?..Cant wait for some details...

I'm sure the boy will be pumping out Custom Billet peices before ya know it LOL
That's good that he shows a interest in that stuff, I'm hoping for the same with Mine

Andy your stuff is always so flippin clean it's discouraging to we mere mortals

what kind of testing will you be doing with the MSD? is it a comparison test against something else?
tell us more about the "ratio testing" as well. what's that all about, just to see if they're really as advertised, or how much difference they make against something else?

Roller cam, 266/272 at 0.050. Mike Jones is an interesting guy to talk to about cams. He does a lot of circle track stuff but he also has some drag race profiles. He posts a lot over on SpeedTalk if anyone is interested in reading some of his posts.

hate to ask about something so trivial, but whos vc gaskets are they? how do they hold up?

moroso makes those gaskets. 93055 is the number. They will last forever unless you do something to them. They work best on machined surfaces and cast valve covers.

One more thing is i only use the center 4 bolts.

you gonna dyno it with that oil pan.. looks like a wet sump pan to me..

505 Dry sump Pedestrian head engine why ?

With that engine combo Dry sump would never even be a consideration.
Under 1000HP dry sump should not even be in the picture.

Thank you for the data but it does not seam realistic ??

No dry sump unless the motor makes more than 1000hp? That sounds like a really stupid rule you made up there.

I could do back to back wet-sump vs. dry sump testing but I probably won't bother since it takes a bunch of time and costs a bunch of money. Nobody is paying me for this testing so it all comes out of my pocket.

I am planning on moving most, if not all, of my future engine work over to dry sump. There are just so many advantages to the dry sump that I doubt I'll switch back to a wet sump configuration now that I have the dry sump. The dyno cell is configured for dry sump testing so it has a big tank, plumbed lines and a remote filter. So all I need to do is plug into that and go.

I like being able to change the speed of the oil pump since that is one thing you can't do with a wet sump pump. I also like the fact that the oil on the pressure side tends to be in better shape on a dry sump system than in a wet sump system. And if I put a larger pump on there I'll be able to run pan vacuum which should help with the power a bit. So basically I don't see any reason to run wet sump anymore on the dyno, even with street motors.

Well the economics don't quite work out that simply. Magazine articles do provide some income but you can't really make a living building engines for $15,000 and selling articles for $1000.

Andy I am curious about the oil pan just like Kens Avenger. It looks pretty deep for a dry sump set up. Is there a reason for the extra depth. Thanks for the posts, you always seem to find something interesting.
