Hi there

Managed to get myself an X51 carbon air box, so it fits better I've also gone with this:-

EuroCupGT 82mm GT3 Throttle Body & Plenum Kit for 997 Carrera C2S, they also sell hose which works with stock air box too, looks good especially the carbon fibre plenum, heres a link:-
http://www.porscheshop.co.uk/acatalo...induction.html

At the moment car has stock air box but I dremeled out the resonator and put in a BMC filter, also got X51 headers and PSE too. Also had softronic map but at this state of tune the difference between stock and softronic map was like 2BHP peak and no change elsewhere. Still the car made 358BHP at the flywheel.

Car now has NHP 200 cel cats and loading the softronic on the car with these fitted could be felt on butt dyno, so softronic no doubt working better with high-flow cats. Car goes to the dyno in one to two weeks to get a baseline figure with the cats fitted. Then the euro cup plenum, GT3 throttle body and X51 air box with BMC filters shall be fitted and car ran again on dyno, softronic shall then be removed to see if it is helping make more power or not with the above.

I shall post dyno plots all together when all done, but looking forward, be good to make 385-390BHP at flywheel.

 

Looking forward to the results Gibbo!

 

I will love to hear from your results, as I have the x51 box, gt3 tb and NHP plenum... I also have the NHP 200 cell x pipes. the x51 box alone is beautiful!

 

Similar setup here. Can't wait to hear the results!!

Hi there

Got an X51 airbox as you guys know, but its missing a part which Porsche can't locate for me as they need a partcode, I've circled the image in the part:-



Can someone please pull this part of their airbox, it just easily pulls off and should have a partcode stamped on it. Can someone post the partcodes which are stamped on it please to help me source a part.

If Porsche don't have it separately then I need to try and get something made up, otherwise my engine will suck in warm air.

 

Hi!

That part is not on the PET catalog. I pull mine off and this is what i found:



it's not a 997.XXX.XXX.XX part...

 

Hi Joel

Do you think anyone can supply me this part?

One more thing the one of the other side is a slightly different size, is this true?

 

Hi there

OK I think I found the part
http://www.autoatlanta.com/Porsche-9...5000-srch.html

Hopefully that is it.

Joel can you confirm still please if they are both indeed slightly different sizes?

 

I just bought the part from the my local dealer and the X-51 side bellows is # sc997-110-252-00. The bellows for non x-51 or the left side (looking at the engine) is # sc997-110-250-00

 

That is the wrong side. See my post above.

 

Disregard my part number. That is for the piece that fits in the decklid. Sorry.

 

This schematic of the regular airbox doesn't show that as a seperate part #

 

yes, left and right are different sizes... the driver's side is bigger

 

I guess best idea is buy that bellow part and then modify it to fit, as can't see anywhere that sells the bellow for right side of X51 air box.
