Took the car to tha dyno the other day have never had it on one yet. I have the following mods: kenetix pend. greddy evo2 exaust, AEM coldair, act clutch and lightwight fly,Unorthadox pully set(trying out some cheep a$$ test pipes no $ at the moment ) and grounding kit. Every dyno I've seen with a stock car is around 240hp etc. I put down 218hp and 213 toque MAX! Whats going on? This was on a DYNOJET. Someone please help, what can it be, one of my mods, a combation of things,I just dont get it? Where did my power go I should be putting down around 280-300 with all that I have done right?

 

Need to see the dyno chart.

 

1) Is yours a 5AT
2) What year is it?
3) there is no way you will be putting down 280-300whp with the mods you have...

cheers

 

agreed.

the person working the dyno may not have used a correction value for the numbers.


and as far as your mods go, you can't just add the numbers the manufacturers provided together and expect that to be your new horsepower and tq numbers. some mods in conjunction with others will create more power while some may counteract each other.

intake should give u sound and maybe some tq, while opening up the exhaust on a non-FI car will yield lower tq numbers and a little more hp due to that fact that you are lowering the backpressure on the motor (needed to create tq). the pulley set should yield positive in both ways. the clutch isnt going to affect tq and hp. the flywheel might, and i stress that, show gains. the grounding kit, same situation as the flywheel. its there to even the electricity currents in the motor and working systems, not so much create power and torque.

 

I know im not around that I was just hoping for alittle more then stock #'s I mean 218? that over 20 less then what I've been seeing. I've been buying the TT bit by bit just getting stuff out of the way like BOV and turbo timer etc. but I dont want to get it all and put it on with out knowing what might be wrong first. I'll get the dyno print out posted soon the air fuel looks funny. I just wanted to list all the mods to see if anyone might have a issue with any of them.

 

a/f?

 

We need to see the dyno sheet and AFR reading..

 

+1

 

you should of done a base run with out the mods first. now you have no clue if your loseing HP or what your gains are. might just be the dyno..
