Help me prove my dumbass friend wrong. He says changing the oil in your car and your oil pan adds 15 horsepower.

 

Sure, if you're running a 1000+ hp car

 

No, of course your friend is right- this is especially true if you drive a Honda with one of those C-tech, or B-tech, or maybe it's V-Tech engines. Heck- those cars are so fantastic you can polish the intake and add 10hp.

Seriously, you can "free up" maybe 4-5 horsepower on an engine by installing a pan with a windage tray and a crank scraper. Changing the oil doesn't "add" anything- you don't think the manufacturers used brand-new oil when they dynoed the engine for the EPA and their marketing department? If you have 10-year-old sludge in the pan and it's stuck to everything else, changing the oil might "free" an amount of power- but it certainly isn't making "more" power because of it- with the sludge build up you just lost more of what it started with to friction.

 

If your oil is bad, or low, then changing it get rid of some possible friction caused by the old oil, and in tern allow the motor to run more efficiently and make more power, but no where near 15hp.

And a baffled oil pan that keeps oil in the sump area, with a windage tray can add hp to around the 10hp mark.

 

Heh, ya, or if your running 20,000 rpm.

Ya... every seasoned veteran uses an oil pan with a windange tray and a crank scraper, because they are trying to milk every last bit of power out of it. But I would say it's 2-3 hp... but maybe something like 20 hp if your in a corner and it saves the oil from splashing up on your crank, at 5000 rpm.

 

I would agree.... it's more like 3-5HP for full on windage + crank scraper.... and you will get nothing from changing oil unless you go to a thinner oil.

 

Every season veteran does not use an oil pan with a built in scraper & windage tray to milk HP, genoius.

Oil control is very important making sure you pump is always submerged in oil....adding a windage tray/trapdoor help this.....the crankscraper, this is basically a $15 mod that requires 1 hr at the most of your "free time" and can net you most likely up to 10HP.....now 10HP for $15 is GOOD IN MY BOOK, and probably the best BANG for your BUCK you will ever get.

 

Synthetic oil is 'supposedly' good for 2% more HP over non-synthetic.

Can't remember exactly where I got that from...I know they did a Royal Purple test in GMHTP about a year ago, might have been there.

 

I guess I misworded it, I didnt mean the crankscraper and windage tray were "built in" to the pan, but every veteran uses oil control.

O and thanks for being rude about it, genius.

 

double post

 

Sry was in a "mood"....sounded like you were poking fun......i took it the wrong way.

Basically a little HP here & there adds up....and 20-30HP more from little things such as port-matching, oil control, synthetic oil, etc... is cheap HP. Something that is often overlooked due to lazyness.

 

No harm done.

You are totally right. The difference between good engines, and great engines is attention to detail.
