The motor consists of:

USDM B18B1
-eagle forged H-beam rods
-je forged pistons (9:1CR)
-ACL main and rod bearings
-ARP Rod Bolts and Head Studs
-Balanced rotating assembly
-Exedy stage 2 pressure plate with 3 puck sprung clutch
-Apexi World Sport II
-Exhaust and intake ports all gasket matched
-All new Gaskets and seals
-AEM Short ram intake
-AEM Fuel Pressure Regulator
-B&M Fuel Pressure Guage
-Dual core radiator
-Wire tuck
-Engine bay painted flat black



not to bad i didn't think, can anybody else re-assure me on this one?

fuel pressure was set at 38psi and the timing was set to stock.

 

no input eh...

 

bump for input!

 

just looking for something to compare to really, thanks for the bump man this thread moves real fast

 

nothing!

 

damn, so thats what mine's gonna be like preboost huh...

 

Just wondering but, don't you think the horse power is a little low.
I have the same motor with just an AEM Cold air intake and dc 4-2-1 headers. I've never ran a dyno on the car but it doesn't feel like I have that low of HP.
I can take an IS300 of the line and no problem.
I though stock was 142hp. dont know abot whp though.

 

yea but u probably lose about 15% through the drivetrain... so 125whp sounds about right... its the "torque" that makes you fast off the line...

 

I'm no expert but that sounds about right to me.

At least its not: https://honda-tech.com/zerothread?id=1387090

 

What is the stock Compression ratio of an LS? 9.8:1? If so then thats right. You loose about 4% or so for each 1 compression you drop. Theres a bigger calculation to this but 4% is the rule of thumb. So it looks like you lost 2% or so from normal. That also looks like one healthy motor.

 

^^^ thanks man but it was 9.2stock i beleive, not positive (it's the USDM motor). The motor definatly feels healthy, it makes some weird noise when in high RPM but i think it's my DIY gasket match job . I am looking for a ls head right now actually to start building it and a new IM. Prolly blox or the jdmshit one

 

The stock compression of an LS is 9.2:1, they say the JDM one is slightly higher but bumping up the compression to 9.4:1 wont make a ***** worth of difference.

The reason the motor made the power it did was because of the mods already done to the car, and the fact that the motor has probably a little over 5k miles on it.

It may not feel like it, but you probably do have that low of HP. LS motors arent HP monsters, thats what boost on these motors is for.

 

hey jon, did you snap any pics at the dyno?

ive got a couple of your car if you want them

This is jon we're talkin about, does he go anywhere without his camera?

I believe he has some on his computer, I think I saw one of your car, but I am not sure.

 

ok numbers for a b18b. I've seen stock (i/h/e) b18b's make 120 whp. You are making 7 more. Torque is avg for an LS motor too. Numbers are going to change dramatically under boost, not hating here. Just stating what I know/seen.

 

^^ thanks a lot man , I was happy with the results for the most part

 

Rule of Thumb:
14.7 psi = 1.0 bar atmosperic pressure. This is what your b18b is under now and it is making 127 whp. That being said suppose you boost it to 14.7 psi, that would double the normal pressure that your normally aspirated motor is under, rendering double the horsepower. Look for roughly 254whp at 14.7psi. Nothing to scoff at. There's my 2 cents.

Wouldn't this vary depending on turbo size and trim? Not trying to be a dick, just curious.

 

I don't know if it's just the air down here, but a basically modded LS (I/H/E) will usually see around 125-130whp +/-, 112 seems a good bit low IMO.

112 is the torque he made

 

my friend just made 235whp on a gsr with 6psi with a 2inch dp and 2 1/4 exaust so i'm thinking that Ill be seeing better number than 245 with a fullrace kid

I've seen stock b16's at 10psi made 320whp with the stage 1 fullrace kit, the non GT kit

what i'm going for: http://www.full-race.com/catal...d=195

oh ya and follow your signature

Yeah it varies a little. It is good to use as a rule of thumb though.

Eat poopay!

Now would be a good time to post up your race gas dyno sheet(the one with vtak )

 

^^^^ what i thought
