I thought Id post this here and see if you guys have any ideas. My car is not making the power it should. A stock SE-R should put around 120 hp to the ground. The first dyno run I did I had an AEM CAI, and put down about 111 hp. The dyno run is here: http://community.webshots.com/photo/...0439XOjVaMGpcI . Notice the line is very shaky. The next time I went I had the AEM CAI, a Hotshot header, and courtesy midpipe (2.5 inch mandrel bent exhaust). I dynoed at around 122-123 hp with that, still very low. In an attempt to fix this problem, I have replaced my dist cap, rotor, plugs (gapped correctly), wires, fuel filter, cleaned air filter, new O2 sensor. I have also reground my MAF, adjusted my TPS voltage. My compression checks out great. My cat is not clogged. My timing is at 15 degrees. Now, here is what I think it could be. The first thing im going to do is have my fuel injectors cleaned and flow tested. I havnt really heard of anyone's injectors getting clogged, but I completely cloged up a fuel filter after less then 5k miles, so thats first on my list. Next up will be some dyno tuning. I am still runing the stock muffler, so I will do a run with no muffler. After that ill do a run with no cat just to make sure thats ok. Then I might play around with my timing some, and also run with the AF ratio probe to see if that tells me anything. If my AF is off, i may replace the FPR (fuel pump has been replaced). Im also going to pull the valve cover and check to make sure my cams are not worn. Anyone have any insights or ideas? TIA

No one knows anything?

Blasphemous

Not all motors make exactly what they should. For example, SCC and AEM both did dyno testing for some part on the RSX. AEM's RSX dynoed like 7hp more or somethin, while SCC's car (brand new as well) made consistently 7hp less with the exact same mods. You might just have a "weak" car.

OMG! You went to Rosen Autosport, that's mistake number one. Those guys do halfass work and if you don't believe me, just ask Gti-R and myself. They did my JRSC install and ending up only hooking up three injectors and messing up a whole bunch of wiring. Anyway, they put the car on the dyno after the install and said it put down 128whp. I got the car back, fixed all their fuck ups and laid down 140whp. Just to let you know, they are real shady and I will NEVER do business with them again!

Hmm, havnt heard bad stuff about them before. I know all cars dont make the same power, but still, that is very low. Definatly not normal. I did not have Rosen actually do anything to my car, just did my dyno runs there.

I'm just saying bro, they're real shady up there. Be careful.
