Just had my car dyno'd. $100 for 3 runs, no tuning, back-to-back. Unfortunately the guy with the videocamera showed up after my run so there's no footage . Makes Ian sad!

Anyway, it pulled 142.1hp and 103.1tq max. Here's the charts + numbers (since the chart's hard to read):

Tell me what you think

 

Good #'s overall but I would had expected the torque #'s in the 114-120...
But good #'s

 

seems to be running good to me could be a little higher i guess but not by much

B16's stock never have anywhere close to that much TQ. 100-105 is the norm.

You expected 114-120 tq? It's rated at 111tq to the flywheel!

 

nice numbers close to my second gen numbers I did 144HP and 98TQ.

My Mods: Muffler tech Muffler, Some Cheap Intake and OBD1 Motor and Stock PR3 OBD1 ECU!!! Also my car was running little rich I can make a little more power with that A/F Guage!!

nice

 

my SOHC has the same torque as that baby!!!!!

i made 121 WHP and 103 wheel torque....

anyways back to ya......
IMO u are running ur car tooooo rich..... seems after 5800 ur engine gets really rich.... in the 12's///// thats t ooo much....... u can get more power by tunnign ur air fuel...

IMO get a FPR, cam gears, cam, and a VAFC or SFC and tune that air fuel.....
not even my friends SCCA race car runs that rich.... and he has 90 psi of gas.....

 

Do you have a 1 million or 5 million series B16?

The tuner said the exact opposite from you... he said it's running lean! AFAIK you want air/fuel in the low 12s for best power. Look at what happens at the VTEC x-over... the air/fuel goes lean and the power dips. It wants more gas. Plus, the tuner said that the reason the 3rd run was down on power was that it was starting to get too hot from running lean and so hard. My last set of spark plugs seemed to have a little detonation on them too.

I have a B&M FPR + gauge and I was only at 38psi fuel pressure (which is stock) so I upped it 2 lbs and it seems to run stronger. I wish I'd gotten it tuned and not just tested now

Sea Hag, it's a 1-million series... Integra XSi. 1991 model year if you want to know

Bossman, those are impressive #s 144 hp from 98 tq... very nice! What did you take it to? I've got a 2" restriction in my exhaust right now and I think that really choked the top end. Power falls off just like stock even though it's got all those breathing mods.

 

raene,

I took my car to a local place here in CA about 80miles away from here.
DynoJet Model 248 was the Dyno Machine.

http://www.raceprep.net/ is their website. Yea you might want to get a better piping to see more power 2 1/4 is what I have.

well hes wrong then

the higher the numbers.... the leaner it is...
the lower the number the richer it is.....

stoich its 14.7.1

on a NA car..... a high to mid 13's on the air fuel its the most desireable place....
u would want to be on 12's if u were forced inducted...

and sorry..... i participate sometimes on my friends tunning for his 2 ITR's that race on the SCCA..... and i think he actually knows what he does.... he has won 3 times.... and its a veryyyyy famous tuner,..... if u dont know who tuned ur car... i might say tell him to check his book.... hes a lil confused

 

I dunno man My tuner has a 7-second car that he's built himself... I'm pretty sure he knows his air/fuel stuff His shop's been open since 1979, when I was born

Resnick's Auto

 

Wait, I may have figured this out... I'm running street gas. Race gas, such as your friend runs - I'm guessing he's running 116 octane or the like - needs leaner mixtures, in the range of 13.0:1 or leaner to make peak power. Pump gas like 94 octane likes about 12.4:1 to make peak power. Since I'm on pump gas and your friend's SCCA racecar is on race gas, it doesn't make sense to compare the air/fuel ratio readings

Isn't it wonderful when we all get along!

 

Here is my graph making similar power with stock exhaust, cat, and a short ram intake, stock PR3 Ecu using both 02 sensors on stock exhaust manifold...

FyI my setup was running ~ 13:1 air fuel ration between 6.5 and 8k rpm. I have never experienced detonation on this motor using 91 octane gas.

Nice Power.

Looks like a Strong Motor!!!

This is what I've heard/experienced myself. Mid 13 A/F ratio @ WOT is about right on a N/A motor (depending on RPM's). But my own personal experience in tuning my Z6/Y8 has only backed up this claim. I leaned out the fuel so that my motor runs at approx a 14:1 A/F ratio before vtec, and a 13.6-13.4 during vtec. These settings are running MUCH stronger than my previously rich fuel curve. I'm also running pump gas.

However, I'll bet you do have a point with the pump vs. race gas though. I'm sure there is a difference in A/F tuning between the two.

 

Very interesting info guys

Sea Hag, your motor's a freak Got an a/f prinout? I want to see if it has that weird leaning-out condition mine does at the x-over. It looks like it does (look at that torque dip! ) but I wanna make sure.

If I hit the dyno up again I'll be sure to test a few different PSI settings and see if it goes up/down appreciably! I'll also play with the settings at the track now that I've got a baseline and see if I can't get repeatability there (I usually run within 0.05-0.1 second run per run so that method's more reliable for me than you might first think )

The a/f saga continues...

And I guess this proves that stock PR3 VTEC X-over is NOT 5100 rpm as everyone says... by both your graph and my graph, it's 4800 RPM!

 

Yeah, when you do I totally want to see the results! Keep us posted!

 

jesus, this proves my B16A is weaaak.

134whp/101tq
B16a1
chipped ecu (moogen program)
DC 4-2-1 header
B&M FPR
open cat
crush bent exhaust
open air element

blah, oh well.

good job, cause other resources basically mimmick what you're saying.

 

Nice, thanks

 

Informative thread... https://honda-tech.com/zerothread?id=95064

 

Track results: I'm in the right lane for all of them; I'm #2782. If you're curious, I raced H-T member Mr. S in each of these races.

First run: No passenger seat, rear tires at 46psi, fronts at 25psi, fuel pressure at 40psi, timing at 17 degrees BTDC, 94 octane (pump) fuel. 14.4 @ 96.5.

Second run: Same setup except rears at 35psi and I removed the front right turn signal for a ram-air effect. 14.390 @ 96.5 (new fastest)

Third run: No changes, but I F-ed up the launch and hit the rev limiter in 3rd, then shut it down way early. 14.7 @ 84.
