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

 

that is kinda of low. i made 155 with just an intake, header exhaust and hondata tuning. everything else was stock.

with those mods, you should be pushing close to 160+whp. What RPM is the peak HP at, I wonder?

Im going to go out on a limb here and say its either got something to do with the MSD ignition messing things up, or the fuel system. I know thats pretty broad, but those seem to be the only two areas that can actually do harm to your power.

What header are you running? How is your timing?

 

DC sports 4-1 header. Not sure about the timing.

Please help.

 

Well, half of your mods won't do anything for power (fuel mods, ignition mods) so you don't really have that much done. Try leaning it out a bit. Most people tend to richen it up WAY to much, which just kills HP.

your mods are not optimal; upgrade to 2.5 inch collector+2.5 inch exhaust, take the msd out(its not needed and might cause problems in the future;hint; ignitor); you say its dyno tunned, whats your AF at?

What kind of im. did you upgrade to? itr?
yeah, not needed unless more agressive cams

It really depends on what type of dyno you're on etc. We always get number like that on our M.D. dyno (rating the lowest, 13.5% under a Dynojet) with B16's so it's not that uncommon for us. We had a customer that came in his an 11.50:1 B16A, headwork, pretty mild cams, all the normal stuff, Hondata, and he made ~150whp and 110wtq. Good Luck tho

 

Only 150 hp that is low. 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.

 

How rich and what kind of A:F were you tuning it for?

 

Not sure how rich but they were tuning for a 12:1 (I think it is stoich or something).

 

Stoich is actually 14.7:1 but 12.0:1 is a little rich for an NA motor... I would probably shoot for ~12.75-13.25:1 as we normally tune our higher boost FI motors to ~12.0-12.25:1. I wouldn't consider where you are now super rich but I don't doubt that your power will come up a bit once you start leaning it out a little further. What injectors are you running?

EDITED and ADDED

 

So it should be a little rich but not too rich.

 

anyone else

 

What kind of Intake manifold are you using. As mentioned earlier, the majority of your mods won't really help your setup (fuel mods, pulleys, etc). Personally I would move up to a larger exhaust from the header back, and look into some upgraded cams, and maybe a Spoon headgasket to help out with compression a bit. It could also very well be the dyno. A friend of mine dyno'd his car on a MustangDyno and then on a Dynojet, all other factors being equal or pretty damn close, he had about a 20 whp difference in peak power.

and take the pulley off do a diy ground kit .

Yea, we've had a couple guys do some back to back comparisons of our Mustang to other Dynojets near by. On average we're ~10-13.5% lower all around. That's just something to keep in mind. Dynopacks on the other hand will generally put out the highest numbers.

well to be honest 148whp for a internally stock b16a2 is very common.
I think with all your mods you may have only made an extra 8-10whp and 1-2 extra tq.

get some cams and your b16 will really scream above 6000 rpm to 8500rpm!

like the other said too. msd, fuel rai and a few other stuff don't really help out that much "at this point"...
