Pineapple Racing Oil Pan is heavier than expected

hey all. i recently bought this part off a good forum member here, and got it in the mail today. it is a MASTERFUL peice, well desgined, and built. it even has some surprises that took me a minute or two to discover! like dual drain plugs and a cylindrical housing for the oil pickup so its fully baffled in 3d.

now, i have held a stock oil pan, and remember it being anemic and light like it was slightly chinsey. this thing...is a tank...at least close to 20 or maybe even more. granted i am sick and everything is heavy atm and i have not curled in awhile, it does take some amount effort to curl the oil pan. its thick metal, i think it would be bulletproof up to a .357 cal LOL.

honestly i thought it weighed enough to be a turbo on my NA, and can see why alot of race guys go stock with baffle (weight and money vs wooo). it may be enough of a weight difference to cancel out a CF hood, really (better placement of weight, but weight nonetheless). but i guess it will be nice to have the extra oil and treat my engine out to a nice part every once and again.

anyone care to discuss the engine benefits vs the fact that now other light weight front end parts are now in place soley to combat a oil pan upgrade? i could always sell this to a someone with a turbo high output motor and go stock with a baffle to save money and weight...if its not going to help out my engine enough to have this on there...discuss? 20 pounds of oil pan + 1 qt oil in weight

I actually plan on installing one of these on my stock ported n/a. Of course it's heavier. It's thicker, larger and cast. It's a much nicer design. It's also there to slightly stiffen the engine and to do that it has to have some mass to it. That few pounds is not going to slow you down. At least not anything that anyone anywhere could feel. The benefits far outweigh (no pun intended) the drawbacks of being heavier.

if your really worried about the weight I can trade you my factory oil pan with banzai brace which has yet to ever leak (running over 500 to the wheels for hours at a time) and you can trade me your PR unit. =)

no difference on track can make up for the skills you can acquire, stop worrying about weight.

I highly doubt it weighs 20+lbs. Its not THAT heavy.

Mines on my engine or I'd weigh it for you

Honestly, even if it was 20lbs you're really not going to notice it. There's a far greater variance in weight between a full and empty tank of gas - and that difference isn't SUPER noticable, but noticable.

the FD is very good, but in most other cars where the weight is can be more important than what the weight is.

best example is the spec e30 we ran last year. built to the rules those cars end up around 2550lbs, its just a steel box with a big chunk of iron in the front. so the weight distribution is not very good, its all in the front, and seems to be off to one side too.

minimum weight for the class is 2750lbs. we ran ours at 2550 on saturday, and then sunday we added a really really heavy spare tire to bring it from 2550 to 2750, lap times actually were slightly better, as the car would actually handle turn 11 at infineon.

oil pan is low in the car, holds more oil, and that works....

Realistically it weighs somewhere between 8 and 10 pounds (I'll weigh mine once I'm home from the office). And yes, at least the weight is at one of the lowest points in the car.

thanks for the discussion, just what i was looking for! i dont have a scale and am working with curling resistance and guesses, of course. the peice is indeed a 'epic quest item', i just wanted to hear some opinions from the gallery. i am pretty weigth conscience on my FC, no matter how much i seem to take off the car it probably wont want to drop below 2500 with the cage, i have even removed all windows and interior.

our old ITS/PS1 car had a hard time getting UP to 2350, and we didnt go nuts stripping it, it still had the tar, and passenger seat, and things like that

depends on if you want to street it too, if its a turbo and stuff...

thats really weird. i had weighed my GTUs at a track day right before the cage went in with a stripped interior at 2600, then added a hefty cage. was yours an s4?

good news! i feel a little better and the oil pan seems to be a little easier to lift (didnt know the sickness got me that bad). its still a little heavier than i imagined, but i think all of its benefits outweigh the difference in weight between what the engine has to carry normally and the +12 bls or whatever. just was a first impression i wanted to have a convo about hehe

haha, figures. s4's are magically lighter, ive found. my best guess is the chassis itself is lighter somehow (less reinforcement?). i've learned to look at s4's and s5's almost as differently as a s5 and s6, but its always been a fantasy to turn a base 86 into a full s5 conversion just for the weight...2300...woah. like i said i dont think ill see the day that my GTUs is under 2600, after the cage.

i'm not sure there is a huge difference, we've got 2 87 gxl's that are 2800+ and my old 91 AT was 2880
