Some of you may remmember my B20 build from about 2-3 months ago. I finally got it on the dyno. This is tuned with a VAFC. I gained about 20whp after playing with the VAFC. Final figures were -
234hp
155tq

Any feed backs? I was expecting more because of the high compression set up -
B20B 85mm with F20B Accord SiR pistons
ITR head, ITR IM, ITR TB, Skunk stg2 cams, skunk valve train, DC 4-1.
12.5:1 cr.
Will post up the graph later.
I'm impressed with the torque because it stayed high all throughout the rom ranges.

 

sweet setup ...
f20 parts rock

 

what rods did u use

 

Good stuff I'm happy to see it worked out, I was curious to see how that block was going to work out for you.

 

good stuff

 

good **** homie

 

Thanks, I'm surprised you guys like the figures. I was thinking they are a bit low. TBH i was expecting around 210whp. Hondata is next on my list anyway. Aiming for high 12's low 13's NA.
Ran 13.5 on street tires this weekend.
Will post the dyno graph as soon as i get the scanner.

Used Stock strengthened rods.

 

was that on 91 oct? btw nice numbers bro.

 

great numbers, especially w/ a dc and stock manifold......why are you dissapointed... you expected 210 but got 230+?

 

Sounds alittle high for that setup...what kind of Dyno? What was the correction factor?

 

Wow you think those are low? I'm with Dave here and think there good or even on the high side.. Especially with only a dc header

 

98 octane.
Heres the graph -



I'm aiming for 210 at wheels.

 

you aimed for 210 at wheels and overshot with 234 at wheels ? that looks like a chassis dyno chart, correct ?

if thats 234 at wheels for the mods listed, thats an excellent setup, not to mention very smooth and clean curve.

Greg

 

I wish dude. Thats 234 at the fly i got 195 at the wheels. What do you all think of the torque line. I'm very impressed with it.

 

uhhh confused? So do you have 234 or 195 WHP??? Arent all dynos for whp?

 

so f20b accord pistons with stock rods too??? i may bite your set up

 

how much work had to be doen to get the f20 pistons on the b20 rods...are the wrist pins the same ?

thats what i ment!

 

what did you to with your vafc to get 20 more hp? fuel curve wise

 

good ****...i am doing a b20 build up over a year and a half...so i have a lot of time to make sure i dont **** up...but yea i was wondering what head would go good w/ a high cr...i was planing on getting high 12 to low 13 compression pistons..but i wasnt sure what head to put on there to compensate for such high compression...but nice setup...congrats

 

either head will work well, if you are getting aftermarket pistons then just change piston specs to give you the compression you like...keep in mind gsr head usually have .2 cr over the b16

 

Could'nt tell ya. I bought the block already built. I'm not an engine builder.
As for the VAFC Wide thr high cam point was richened by around 20% and afew other places leaned. It was the tuner that played with it at the dyno. Personally i reckon he's gone too rich. I had a glance at the AFR and in some instances i was seeing 10.2!!
Hondata next!!

 

nice setup

makes me anxious to have mine fully tuned

 

[QUOTE=HondaIntegraR]great numbers, especially w/ a dc QUOTE]

Any suggestions on what header to use next?

I would like to know as well. If they are a straight drop-in, they would be a good, low-cost alternative to expensive and clattery forged pistons.
