The HC rules say the oil pans can be modified, but does that mean the aftermarket oil pans can be used? Any rules nerds out there.......... help me out.

 

James,

How do you interpret that rule?? hmmm..I think its a bit grey.

 

``Modified oil pans may be used''

The Moroso pan is a modified pan .. works for me. Or maybe, I modified my pan to look just like that Moroso one.

info@honda-challenge.com knows for sure.

A spoon/mugen pan is a modified stock unit, rather than a band new unit (moroso).

What defines modified? Does the pan have to be stock other than baffles? A pan could be cut up and re-welded like the moroso pan as well if that were considered still a stock pan.

 

Either way, your still going to be slow James...

 

I don't think you can gain any power from a aftermarket oil pan, you will just save weight. And with there being a min. weight for each car it does not seem to make THAT much of a difference one way or another. So I'm thinking they MIGHT let you use the aftermarket oil pans. = I don't know

 

the point of an aftermarket pan is not for weight - its for baffling.

 

yes... oil starvation is the DEVIL

 

Me thinks, James, that the answer is in your question. which you ask by yourself differentiating between "modifying" the stock one and "using an aftermarket oil pan." They aren't the same thing.

Kirk the NERD

 

Easy way around Kirk's interpretation...

Buy the Moroso.
Using a hole saw, cut out a 1" diameter circle from stock pan.
Using a hole saw, cut out a 1" diameter circle from Moroso pan.
Weld 1" circle from stock pan into the hole in the Moroso.

You now have a "modified" stock pan that looks and functions an awful lot like the Moroso.

 

Man .. I hate this kind of rule nerd crap. Ask Karl, he will let you know for sure. Either way, under national HC rules, oil pans are free. I don't think any1 will care if JE has a Moroso in 2003.

 

We all do. That is why rules should be as straightforward as possible. That's why allowing "modified stock parts" isn't much of a rule (and likely why SCCA IT and HC-National allow any oil pan).

 

The "stock car" formula that the TransAm went to in the early '80s grew naturally from the series' modified production car roots. In the '70s, teams were allowed to "lighten and reinforce" suspension piece (in the name of safety and longevity, y'know). One lateral thinker lightened his A-arms completely away and "reinforced" the vacant airspace with tubular parts - ta-da! Tubular. Finally, someone said, "Gee, this is dumb" and wrote the rule that explicitly allowed replacement of not only the A-arms but pretty much everything else. Wonder why I am a NERD? I have watched this cycle over, and over, and over...

Oh, I don't doubt it. As far as I'm concerned, rulesmakers shoud either spec parts explicitly or not spec them at all - anything in between leads to the A-arm situation you described.

 

Funny...just what I thought this morning.

 

Crack Monkey your interpretation of the rule is dead on!!!

I simply took 2 inline 4's welded them toghether and made a honda Vtec V8. They are stock motors. 1.5 ltr to be exact. I want to run in H5.

Does the rules say anthing about a motor in front and a motor in rear they are stock just modified.

 

James, I had this discussion last year. It is technically illegal. They never clarified the rules. Modified stock pans only.

You don't want the Moroso anyways. It oil starves on turns. Yeah, great... An aluminum oil pan that costs $300 and starves on oil.

Warren

 

You know first hand?? Ive had oil starvation around several corners & my psi was low I was hoping the Moroso would solve my problem. Besides an accusump... what other way could I stray away from oil starvation??

Vtec not kicking in around corners = fawrk

Pete

 

I've heard the same as Warren says about them, although no personal experience. Spoon/Mugen are the only other brands, I'll baffle mine myself one of these days.

 

I thought Canton only made a D-series pan.

 

would be kind of tough to weld aluminum to steel wouldnt it?

 

Funny I should read this thread tonight as one of the things I did today in getting the sold race engine ready for delivery was to take pics of the modified oil pan that Comptech did for me (at solid cost). Here is a pic and should be HC legal since it is modified. I had heard of an SCCA non-IT racer lose a motor or two and the comment I heard from someone else was it was caused by him "playing around with those Moroso oil pans". Don't have first hand knowledge but the comment came from someone who should know.

Here is what Comptech did on my CRX engine and I will do on others. Basically it is improving the oil return to the bottom chamber to keep oil down by the pickup instead of sloshing around on top of the baffle:

 

do you have a picture of the stock oil pan to compare them? that would help alot.

thanks

Not readily available (all are on engines right now) but the only hole that is there from the factory in the line of holes near the top is the oval where the dip stick pops through. All three of the rectangular holes are the new modifications in what was previously just flat steel. Looks like they drilled round holes to locate the position then cut the lines to create flaps then rolled them up to be scoop-like.
