Re: Cutting patterns in metal
How about a basic jigsaw? I have a vertical bandsaw, but the problem with most of these is that the blade speed is set for wood so it's way to high for metal and you need a step-down gear to run a metal cutting blade.

Re: Extended sump question
EMPI has two different finned slimline sumps; one is 1.5 quarts (probably the one Jim is referring to) and the other is 3.5 quarts and about twice the size.

Re: Extended sump question
And if you had more space to work with, you could probably incorporate swinging trap doors into the sump to retain oil near the pickup.SR Racing wrote:You could also fabricate a sump that would be wider.

Re: New manifold rules in GCR
It is MY opinion that you are not INTERPRETING the rules correctly. This is good, it means that there is still a lot of gray area to work in. I didn't think I was offering an interpretation of the rule, just trying to read what was added to the new proposal compared to the old. Sure there is a lot ...

Re: New manifold rules in GCR
So basically the change is that you can't reduce the thickness of the metal from both sides of the tube to allow stretching the ID within the existing OD limit. As a newbie, I was surprised to learn just how much alteration is being done to these "stock" manifolds and was a little taken ab...

Re: Extended sump question
I can send you AIM data files showing peaks above 1.4G at several tracks, although it's typically closer to 1.3G, which is plenty to uncover the unbaffled stock pan I was required by rule to run until last season (and still do because I'm satisfied with the Accusump's performance). I also have data ...

Re: Extended sump question
+++ EVERYTHING you just wrote except the lack of a front seal and being a flat four applies directly to the 302 in my Mustang, or the engine in any other production car that is road raced. The Vee engine is just not that unique of an application that it makes the Accusump ineffective. But I'm done ...

Re: Extended sump question
Canton recommends 7-10 lbs. Anything less than that and you won't even get full use of the oil in the canister. And as I mentioned, a warm vee idles at under 10, so the canister will empty at that point. Another draw back to a accusump with manual valve only, is that point when the tank does drop m...

Re: Extended sump question
Canton recommends a base air charge of 5-7 psi. The rest of the pressure in the cylinder is created by the pressure from the oiling system. It may discharge some of the contents at idle, but that's not really what you care about. It's in the high-G corner with a momentary loss of pressure that you c...

Re: Extended sump question
Jim, I don't completely agree with your description of how an Accusump works, although not being very familiar with Vees, it may very well be that they tend to push some oil out due to the poor sealing. For one thing, the plumbing is the same for either use as a pre oiler or a "safety" dev...

Re: Extended sump question
I'll ask again about an Accusump, since it's already legal and cheaper than a dry sump system. Is there any reason NOT to use one? With the external coolers most engines have, plumbing one is simple. The only objection I could see is weight and locating it, but the 1-quart Canton Accusump is about t...

Re: Extended sump question
Does any one run an Accusump in FV? They are allowed per GCR 9.3.1. I've run one for years on my Mustang with a stock pan and it definitely works, which I can prove by having "accidentally" data-logged oil pressure with and without the vavle open a couple of times.

Re: FV Racing Sim Development
That's nothing. You should see the real simulators they use in F1. I saw one at the SAE conference in Detroit a few years ago. Imagine a cockpit on a platform mounted to a series of hydraulic actuators surrounded by a series of flat screen monitors that reacted to the actual forces on the car while ...

Re: Aftermarket shock mounting
Thanks. I did mean the front, and that's pretty much what I figured would be the method, just wanted to confirm before I started drilling! It's going to be much easier and cheaper to run SAE than metric anyway. I priced some metric 12.9 bolts at the hardware store at over $3 each!

Re: 23x5.0-15 Hoosiers?
Size, weight, construction, and speed rating are all unique for land speed racing. There aren't very many tall, skinny tires rated to 300 mph. Goodyear hasn't made Bonneville-spec tires in many years and the existing supply of tires is all there is.

Re: What oil and weight for summer in New England?
Calling these engines air-cooled is somewhat of a misnomer. The cooling of a Porsche/VW/Harley-Davidson, etc. engine's internal parts is done as much by the oil circulating through it as the by the ambient air forced over, through or around it. This is true of a liquid-cooled engine to some extent a...
