DOHC-DX

it is completely untuned. i was a bit disappointed on the HP numbers. 130whp, 120wlbft. just look at the torque curve tho!! nearly peaks at 2k rpm! torque is on top, HP is the bottom.

Those are nice numbers, why disappointed? The LS is a wonderful motor for sure, and it's impressive to see people building them NA. What kind of cams do you have in there?

IM ALL BOB

well when I dynoed my stock LS with just a tanabe exhaust.. stock everything else .. it hit 123whp/117lbs torque.. so your engine is strong at least.. begin the mods =P

I think those are pretty good #s and a nice torque curve for sure

functionFiRst

you shouldn't be dissappointed with those numbers...you should be dissappointed if it's 109 Hp to the wheels.

sweet figures man, btw how has CHB been treating you?

<=- hatchback from CHB.

Thats not bad considering that your engine hasn't gone through any tuning yet. And, LS B18B motors are 142 HP to the flywheel. At 130whp, that sounds about right. Get you car tuned and you should see higher numbers. Cam gears, cams, fuel pressure, timing, etc.... will all help you.

DOHC-DX

yes, adjustable cam gears are my next mod along with p30 pistons and 11.3:1 CR.

then, back to the dyno for tuning. this was basically a baseline. after the pistons/tuning i'm hoping for 170whp/155wtq

more comments needed

gamby

There are plenty of B20's that only put down 120 to the wheels (I'm referring to B20Z's).

You're in pretty damn good shape.

HXMan

I really don't think that will happen with just higher CR and tuning. Sorry but you will need more then that.

vovinamer

vtec head will give you more impressive numbers, but 130 wheel is pretty good

DOHC-DX

yeah, probably true. those numbers were just a guestimate. i forgot to mention ported intake manifold and overbore t/b along with the pistons. possibly even hondata intake gasket

rainmanEK

im sure with those pistons, a vtec head will get you there! eric

DOHC-DX

no, LSVtec is not a route i am going to consider. i'm not a master engine builder, so i am not going to risk the notorious un-reliability of a half assed built LSvtec.

thanks for the input so far everyone

Yes a lot of B20s put down 120 whp stock...add a decent I/H/C/E setup to a B20 and you're looking at 135 - 140 whp.

How aggressive are your reground cams? What aftermarket cams to they compare to? Nice torque curve by the way

DOHC-DX

they are pretty mild. they have more duration, which is what i'm attributing the low RPM torque to. i believe the regrind was performed by schneider. they are very close to the webcam 148e in numbers. i have all stock valvetrain

typeRdriver

sell it and buy a type r

DOHC-DX

yeah, ok... thanks for such valuable input

to bump that HP # up, is a skunk2 manifold worth it, or should i just port an OEM one?

typeRdriver

na im just jokin man .... good numbers for what you got. keep up the work

Hyjnx

I wish i had a tourqey monster...Nice run!!...bet your a quick one off the line ?

DOHC-DX

well, as long as i get traction. my best (and very first) time dragging was 15.4 at 92mph. that was with LSD, soft street tires, and tons of wheelspin.... in 90+ deg weather. now i know why i spin so much

with practice, i hope to be at 14.8-15.0

i got a skunk 2 man...and i think its worf it..i felt the hp gain of coursee..and some whistlin..ppl think i have a supercharger..butt....i really don't kno how much it compares to portin the oem..it might be the samee...and cheaper...but skunk 2 man is really worf it skunk 2 is easier too...u jes buy it and put it on...and plus u could sell yer stock manifold too..for those doin b20vtec or whatever...
