Re: oil retention devices
 

Jeff, I am a paid member of both the NHRA and IHRA and posses a competition license in both as well. I am not sure how to take that statement. Are you asking me to leave the forum simply based on the fact that I am not class racer? Or just making me aware that the NHRA rep is not interested in hearing any pro's or con's from a non-class racer?

Re: oil retention devices
 

Why not just legalize Dry Sump systems? That would at least have the added benefit of improving performance.


And VIc S......... 11 quarts ???? ...you sandbagger!
If you cut it back to like 8 quarts it might cool down a little bit quciker & Just think of how much weight you'd save LOL

Jeff Lee: Sorry but my old eyes glazed over at about posting #35. We are in total agreement.

Racer6x64: The oil temperature issue is: the hotter the oil the thinner it is. The thinner it is the it's ability to protect the engine is lessened, oil pressure is lowered, oil flow is increased (emptying the pan quicker) and more oil migrates into the cylinder. Once all of these changes are dealt with there is no "issue".

Angelo: Remember all of those engine changes Dean and I use to do? I was running 8 qts. 11 is much better and cheaper!

Re: oil retention devices
 

Just what I made in bold.

Re: oil retention devices
 

Does that mean that the NHRA ACTUALLY DOES CARE about what class racers have to say?

Just asking...

Re: oil retention devices
 

Since I have involvement with both S/SS cars and .90/ Bracket cars ,I have a few points to make............I've run a diaper on my SG car for the last 6 years , I can tell you oil temp is not an issue,but cooling the car between rounds is. .....When the hot lapping starts ,I'm lucky to get the coolant below 160 deg..The oil temp stays around 180, which is where I want it. [btw ,I run 5w30 ,not 50w] ..look at any of the racing oil sites ,or ask someone who spends a lot of time on a dyno ,You'll find the optimal temp for oil is 180 to 200 deg.........Is the diaper a pain to work around at the track, you bet! ..............does it drag on the ground in the pits or on a wheelie ,you bet......Do I want to put on on my Stocker [ or any of the S/SS cars I work on ?] ,No Way.,even tho having one probably saved my SG car a few years ago..............I will say this, I think ATF leaks are a far bigger problem than the ocasional oil down from a S/SS car. ...........That's a problem that can be corrected with a $30 puke tank , [ and I wont have ATF dripping on my head when I work on cars with Metric 200's ]...............Tom

I've been involved with Diapers since they became manditory. My Alky F/C never had one. Every engine/rod failure with my Top Fuel Car(s) and since working on Jim Head's Funny Car results in and saturrated over flowing diaper. THE ONLY thing that saves an Oil Down is a correctly designed and sealed belly pan with fore and aft baffles to stop Oil Shosh. After we hang a rod out we carefully let down the belly pan that is usually full of oil along with the soaked diaper. This is the rule not the exception with Nitro Cars. Did I mention we run Dry Sumps? IF diapers were the cure all, then why are there still oil downs with the Nitro Cars? Why are belly pans manditory also? My feeling's are quite simply that a "universal" Diaper for stock/ss is impossible. The containment is too close in proximity to the headers and the risk for fire is multiplied. I personnelly will not run a diaper on my car WITHOUT an on board fire system. When they pulled Al DaPasso out of his Alky FC in BG , KY in 1992 the meat (muscles) of his lower legs were hanging off the bones like a cooked chicken. ( He died several weeks later.) I prefer for that not to happen to anyone ever again. MY point ? I hate Fire. Hit a guardrail,... spin out,... flip........NO problem .....I hate fire.....What's next? Fire Suits, and Hans Devices? Give me a brake! ...PS... for all the non Vietnam Vets out there, Go on line and look up how Napalm is made; Take a little Gasoline, Mix in a little Aluminum, add some Oil, etc. etc., sound Kinda like the contents of an oil pan?
