I got a b16A2 with lots of bolt on mods. With all fuel mods(rail, pump, filter, regulator), CAI, 4-into-1 header, tester pipe, 2 1/4" exhaust, pulleys, Intake manifold, Msd 6AL, MSD coil, MSD plugs, VAFC V-tec controller, dyno tuned, but the power is still very low. My numbers at the wheel are 142.8 hp and like 102 tq. Dont unterstand why the horse power is low? Been told that it is the intake manifold. Also been told it shoud be making more like 155hp-160hp.

Running very rich when the VAFC is turned off.

Also the compression is like 195psi in 3 cylinders, and 185psi in the last

Also when i installed my IM (Skunk 2). Could it be i accidently switched plugs on the map and tps sensors.

HELP

EDIT: Nevermind I just reread your post. Those numbers are pretty damn low. Maybe a set of cams would help open things up? I would check all your sensors too like you said.

Formula 1

those numbers r way low i put down 167 on a gsr with i/h/e/ that was running hella lean too

u have way more fuel mods which shoudl help i would guess something is up with the fuel pressure ( get a regulator) also the map and tps could be switched? but u shoudl get a cel? also 195psi is not good u shoudl be on 210 plus i hit 190 psi in jdm gsr a tooth off in the timing belt so that is what i think

ask the guys at the dyno what they think...they usually have a good idea

also get the wideband next time you run to check out your a/f ratio

I dont know what is wrong. The guys at the dyno said that my car is running pretty well but te HP numbers ar just low. The odd thing is when they turned off my vafc the A/F numbers were really rich.

did you check it yourself? or have it read by a computer?

take it to autozone just to make sure....

ORcivicsi

Read by a computer.

all i got to say is wideband

ORcivicsi

they did use a wideband sensor

Like everyone else said that is damn low, i have seen a si with just i/e and put down 141hp. I dont see why it would be the manifold though.

blinkn09

wow that's really low....i got a stock A2 and it dynoed 145hp with 106 Tq at sp engineering...sorry man i wished i could help

blaster834

was that at the wheels or at the crank??

First things first. What dyno were you on? What kind, it DOES make a difference, some read lower some read higher. What are your 1/4 mile times like?.......If all else fails, start removing mods 1 by 1 and find the culprit.....Also, take it to a different tuner this time around, just for ***** and giggles............John
