i just did a dyno run on the weekend. My first dyno run last week was 144.7 at the wheels and 130-ft-lbs. I was running too rich so on the weekend i used the O2 wideband and came up with these results:
fuel pressure dialed down-70-73 at WOT
BTC set at .5
157.2 at the wheel> 189 at the fly
141.2ft-lbs> 170 at the fly
Does this seem right?

You are running 6psi, correct?

YES I AM RUNNING WITH A 6PSI PULLEY!!!!

i don't know what else to do besides dialing down the BTC to 0 degrees, but i don't want to detonate the car.
FASTFOUR> you have a v-tec right?
I don't have a v-tec in my car.
that should make a difference right?

I have an LS motor (non vtec) but use a VAFC. It works just fine no matter what anyone may tell you. You would be able to fine tune (as much as you can w/o a standalone) the a/f ratio's and probably squeeze 5-10 more hp out of it, not to mention the gains it may give you throughout the powerband.

what other mods do you have to make your LS motor at 168.8whp and 137ft-lbs
That 10hp gain against my 157.2whp and 132ft-lbs can make a difference. For example a header can make up the 10hp!
BTW what is the VAFC?
Defconsc
------------------
There is still more in it I'm sure. I hit 168.8 and 137.2 (now 165 and 137) before my AFC. There is more in it, you just have to spend lots of time on the dyno.

The DC 4-2-1 gave me 5hp to the wheels over the DC 4-1 and my 3 inch custom CAI made 5hp and 4tq to the wheels over the AEM CAI. There is 10hp right there. Those #'s were all dyno proven as well. The VAFC is a device from Apex-i that allows you to set your VTEC point and play with a/f ratios. Since I don't have a VTEC motor I just use it for fuel adjustments.

I should be able to get 160 from my ex correct?

The most I've seen from the SOHC with JRSC is around 140.

Man, I hope that's at the wheel! Considering the SOHC has 130 at the crank. Figure with a 15% drivetrain loss of 20 HP, the JRSC gains ~30 HP on an SOHC. That's like a 27% gain.
Tom, you'll have more drivetrain loss considering your automatic.

USDM SOHC 1.6L VTEC motors produce 125-127 flywheel horsepower... so if you reduce this to wheel horsepower (deducting drivetrain friction losses), you typically end up with about 105 to 110 HP. If you multiply this figure by Jackson Racing's typical claims of a 35 to 40% increase in power, this would yield 142 to 147 wheel HP.
If you could get 160 wheel horsepower, you have done a great job... especially at stock boost levels.
The highest dyno I have seen on a SOHC VTEC 1.6L is 183 HP at the wheels... the next best being the Zdyne powered JRSC CRX at 176 HP.

Mario (d-x factor) got 150 at the wheels on his dx motor with 8psi pulley and some bolt ons. how much do dx motor makes at the wheels? 90? just seems wierd.
