Should the SFWD class be able to use an external oil pump or dry sump?

How would using an external pump / dry sump make this class better or worse?

Wouldn't most engine builders agree that the factory pump is inadequete.
The Corvette uses a dry sump, so streetablity is not the issue. I would like to hear everyones opinion on the subject.

 

It'd be cool at times I guess, but we've never really had any huge problems with factory pumps. Don't get me wrong though, we've definately broken a handful of them, so it's sort of like trannies... Seems like thing would get a bit cluttered in a factory Honda engine bay though, I dunno? On a race car, hands down no doubt. Just my $0.02 though.

 

no

everyone had this discussion last year and the answer was no - the answer is still no - seems like everyone is doing a great job with a stock oil pump for the most part - it is definately not really something to be concerned about, just assemble your engine correctly and with care and go racing - you can pretty much ask any of the racers at the top of the class, seems like the stock stuff is working just fine for the majority of us, some teams did have some small issues this year but they have pinpointed the problem and fixed what they needed to - the engine in our car right now has probably close to 200 quarter mile passes on it and numerous dyno pulls on the same OEM oil pump with no worries in the back of any of our minds (knock on wood)

here is what will happen i guarantee you if they allow them - first they allow dry sump systems, then everyone wants vacuum pumps, then methonal, then a weight break, so on and so forth until the whole meaning of this class is lost amongst the dire need to outspend each other

so the answer is still no

 

With the amount of power everyone is making, a better pump is a must. The problem with the dry sump is that it takes room for the oil tank, external pump, lines and filters. I think the object is to keep these cars to look like street driven. Maybe the answer is to pull some power out of them.

you don't need 900 whp to go mid 9s in these cars - this has been proven time and time again - quit trying to win the dyno contest and setup the car with a decent amount of safe power within the rules that are stated and everyone including the sanctioning bodies seem to accept at this point in time and get some seat time

we aren't talking about dyno'ing in Utah here, simmer down

 

Everyone knows I just love post about dry sump systems. James is correct that the Nhra answer is still No, but they can be ran in Nopi events with the engine diaper. We don't want to miss out on the Vegas and Bandimere Nhra events this year so guess what? We are removing the drysump in 2006. It will set on the shelf for now. Planning on 3 Nopi events as well.

It would be nice,but,i dont think the class needs that right now.
A well balanced motor and a dampner should do the trick.

 

Might as well allow an xtrac or the new gforce tranny at the same time, but that's not gonna happen because I wouldn't consider it, nor would others, street legal. Street driven, maybe, but not stret legal.

 

what rpm does everyone shift at? im doing some research and this info would be great. im not trying to get NHRA to allow dry sump but an external pump would be nice. they require us next year to run a motor / trans oil catch pan. how much of a streetcar does that resemble?

if tis is true why not just allow a EXTERNAL WET SYSYTEM i mean if they are makeing 200 1/4 mile passes and 800 whp on a stock oil puump what would b the dif if ya used a external wet system ,this is supposed to be a class for tyhe average racer i cant see the average joe building a built to the hilt motor for this class to compete and haveing to worry bout a oil pump going and killing him for the rest of the year being that teh average joe does not have money to build a killer motor and have a backup your talking bout thiusands of dollars that the average joe dont have plain and simple ( not talking bout a guy taht says he is the average joe mean while has parts given to him for cheap if not free) and run stickers on the car for it (wich i personally think should not be done cause most of that is for sponsorship anyway ) maybe they should have 2 sfwd classes sfwd1 and sfwd2 with a t3 turbo limit in sfwd1 for the no-frillls racers
