So went to the dyno yesterday to tune my V-AFC. Came up with some decent results.

I managed to pull

216hp@7400rpms SAE
171tq@5600rpms SAE

Temp was 83 degrees F and the power correction factor was about 1.055

I was pretty happy with the runs considering this is my full street setup...this is with a catalytic coverted that crap dual stage manifold, and no cam gear tuning.

I have the entire data readout, so I will be constructing some graphs tonight to post up. A/F is decent but I need to fine tune it still.

Setup:
Intake
AEM CAI 2.75", K&N Cone Filter
64mm TB , IM ported to 64mm
Hondata IM Gasket

Fuel and Ignition
AEM FPR
Stock Fuel Rail
Stock Fuel
Stock Fuel Filter
RC 370cc injectors
Stock Ignition and Coil
TechTom P72 (like a hondata)
Apexi V-AFC

Head
H22A1 head ported by Top Power Racing
Valves deshrouded, head milled back 10 thou
Crower Stage 3 cams
Skunk2 cam gears
Jun Valvesprings
Jun Titanium Retainers

Block
H22A4 Block
89mm Iron Sleeves for 2.3L displacment
H22A4 stock crank, H22A4 crank 55mm mains
Crower ProBillet H22A I-Beam Rods
ENDYN Rollerwave 11.89:1 pistons and rings
Stock Head Gasket bored to 89mm
Prodrive oil pump gears
Power Enterprise Super Strong Timing Belt
H23 manual tensioner
Balancer belt still on

Stock pullies
Removed A/C compressor

Exhaust
Trust/Greddy SS Header
Random Technologies High Flow Cat
Greddy Power Extreme 2.5" catback

Drivetrain
Clutchmasters Ultralight Flywheel
Clutchmasters stage 3 clutch
Accord Euro-R Transmission w/ LSD
1-3.285
2-2.090
3-1.481
4-1.071
5-0.812
F-4.266
ES motor mounts

Keep in mind the LSD causes a good size drivetrain loss too

As you can see from the setup there are lots of ways to gain power...I'll get to that probably over next winter

nice numbers mang!

All motor.

 

can i drive her?

 

you said your ecu is like hondata...then why the v-afc?

 

very impressive. Btw-where did you get your jun valvesprings and titanium retainers? Or where can I? I have been looking for somewhere to buy jun/ thanks

 

Nice numbers man. How much do you think you'll be able to squeeze out of your current setup w/ proper tuning?

 

he just has an intkae manifold gasket.

 

Nice numbers. If you play with the cam gears some you could probably squeeze out a few more horses. Other than that you have a pretty solid setup..

 

 

nice for a partial tune... get some real engine management and finish up the tuning and you should see quite a few more hp from that engine

 

nice #s on just a vafc. and torque is very good. same as 2point6.

yea like mentioned above u should get hondata. and you should be able to release some extra Hp.

 

nice numbers

The Techtom is like a hondata in that you can adjust fuel and timing, but in one shot only..like the chip costs $700, so you only burn it once. It was previously done with the old H23 VTEC stroker motor. So while the tune is similar it's not right for this motor. So I have the V-AFC to adjust the fuel.

My main drawback is that I can't improve my timing at this point. It kinda sucks cause I was running 14+ A/F at wide open and I wasn't detonating or anything, which tells me I have a fair bit of room to advance timing...oh well...A/F is 13.0-13.7 now.

 

Are you plannin on getting any dyno numbers without the balance shafts runnin???

 

oh did you ever find out where your redline is....or find where it droped off

 

Here's a graph I made in this graphing program with all the datapoints...I will figure how to add an airfuel and add that next

....added to first post

You can see that with some cam gear tuning and a better IM I could get a higher peak power

nice too see it pull to 7500 atleast..most start to fall at 6700

for sure with the crappy *** IM its being held back...cam timming is going to be sweet


oh and i need a ride again im itching

 

Needs a header

 

Nice HP and numbers The lude must pull like a mad dog!!!

What do you call this? A ham sandwich?

 

wow! super nice numbers!

 

ya thats true with all the new headers out there like prospeed and smsp and there another one to very nice lookning ...guys are picking up 10 or more hp

so buy one of thoses and ill take you greddy for super cheap since it sucks soooo bad

A little too much....I get noooooo traction right now but it's a ton of fun on the highway

The greddy is nice....but I agree if you look at the simple size of it should be considered somewhat restrictive for an all out setup....

I think intake and exhaust are my main restrictions...I need a better Intake Manifold, a bigger header eventually and to run a test pipe.
