In each different tuners website they claims around 10HP at least for each part so what numbers of HP can we expect from all these parts together

plenum 15 to 27HP
ecu 10 to 30HP
muffler 0 to 12 HP
cats
headers
air filter 10HP

 

All in all .. you will be lucky to get ~30hp out of all of them.

 

Agreed!!! Then again, I have all those mods, just waiting for sometime so I can dyno my car

 

For the money spend on every single one of those mods, you're close to supercharger territory which would yield so much noticeable horsepower. I would guess 30hp to be gained from all those mods. You can't add all those numbers up to get a total because it doesn't work that way, instead those mods would just work together to push out a total of 30-35 hp.

 

Depending on whose FULL exhaust set up and mapping you use, e.g. Cargraphic, Supersprint , FVD, AWE, with the plenum you will see 30 to 38 HP @ the crank easy.

Everyone stretches the hp figures, with a X51 option you only get 26 hp, why would the other guys give you much more? 30 is realistic.

Look at the post re: Viagra, if you put 4 pills in your tank, you'll get renewed vigor in your engine.

 

i didnt feel anything noticeable...........until the sc'er

 

Let me explain why you would get more from the other guys. Look at the header design of the guys I mentioned , then the X-51 header. The X-51 is a little diffrent from stock design wise. IF you get 2 HP gain .... that's alot. The equal length , spaghetti style header delivers the proper flow out of the exhaust ports to deliver the added tq low end, then work properly with 100 or 200 cel cats at mid to high end. Then you add the plenum , which works well, and a good ecu re-map, you will be over 30 HP easy.

agreed... equal length headers and 200 cell cats with plenum makes a noticeable difference!

 

so your car goes from 350 to 380 hp.... do you really think you can tell the diference with 30 more? it probably translates into tenths of a second with respect to performance gains. get the mufflers for the sound for sure. get the supercharger for gains. buy all the extras after the blower if you want to squeeze a few more out. the smaller mods on here are great for tinkering, but don't expect anything dramatic from them. i'd be surprised if your seat 'o the pants meter could even detect these small performance mods (ie ECU, etc).

 

most DEFINITELY!.... on the track on a long strait away its the difference between somebody staying with you and you walking them... by several car lengths by the time you hit the next corner.... gives you that edge... and yes you can definitely feel all those parts working... especially @ higher RPM.

personally I stay away from supercharging because of the load it places on the engine not to mention catastrophic engine failures and premature deaths caused by forced induction kits... normally aspirated is my preference and these parts definitely do the trick... reliably!!

My point exactly +1

 

i would love to see a stock c2 run against your car down the straight. i'm guessing the difference would be insignificant. i'm sure part of those pereived gains are from dropping that stock lead weights they call mufflers i don't think you're "walking" anybody as a result of adding 30 hp on a chubby 996.

for example, I ran one of the members on here in his 3.6 liter 997 back when my car was stock. so close you almost couldn't tell the difference and he had another 20 or so HP on me. (edit: he had the 3.8 liter)

 

that's what I think but if these numbers are right (www.vividracing.com) 30HP from their ECU, (www.roadsportsupply.com) 27HP from intake plenum, (www.evoms.com ) 10HP from air intake and (www.awe-tuning.com) 12HP from exhaust system we should get more than 30 HP easly

simply if ECU or plenum alone can make 30HP we can get more from all parts together

its not insignificant... especially down a long strait away... go to the track and you'll see , especially above 4000 rpm you'll be pulling !

ok... NOW your talking through your butt... you beat a 3.8 yah right... (maybe he was a gear higher.. lol... ) tomorrow you'll be telling us you beat a turbo....
