a big thanks to mainstream performance for letting me use the dyno jet !
http://www.mainstreamperformance.com


i have a mildly built b16 with
JDM DC 4-1
2 layer headgasket
toda flywheel
custom 2.5 inch exhaust
custom ROCKET chip

everything else is stock






the blue line is GSR cams, the red line is b16 1st gen cams

i use a wideband on the street, so the a/f was dialed in right when we hit the dyno on the 1st gen cams

i swapped to the GSr cams on the dyno and proceeded to lay down 146 whp untuned. the AFR's remained close to the same as with the b16 cams, and with a little tuning, i managed to get 148whp out of it with a 12.5:1 AFR. anything above that would start to loose power, and i tried AFR from 12.5 all the way to 15:1.
as you can see mainly the top end suffered on the GSr cams, while the bottom end was a hair stronger.


any comments are welcome. i think i could have gotten a little more out of the b16 cams with more tuning, once i noticed i was getitng whp out of running richer on the GSR cams

hmmmm, very interesting, i would have figured slightly higher numbers from newer GSR cams vs 1st gen B16 camshafts. GOOD numbers on your B16 though IMO considering cars with similar mods i have seen make 135-140

 

redy to race?


there will also be a IM manifold test coming up soon!@

 

CRX>CIVIC anyday, even when you had your built GSR, you know i cant lose, if i do, ill be the worst roomate you ever had

You should do the 2nd gen B16 manifold against both itr and the 1st gen B16 ones. A lot of people have mixed feelings about the subject to which makes the best powerband.

if anyone local can provide them for me, ill test them!

at the moment its going to be a 1st gen mani Vs a AEBS

 

cmon man you know your roomate has got the hook up BEYOTCH, i got one for you buddy

 

I may can get an ITR mani. for you to use

 

PM me and we can see what we can do

 

Go Murph!

You need a better intake pipe.

 

ZANE IS THE MAN!!!

 

Interesting.

 

i know rocket, i need to do a battery relocation to get anything worth while in there...


itl happen soon.

 

looks good as always good numbers! ill give u a hand with a battery relo if u want. see ya round

that would be incredible.

Nice numbers man.
I like seeing stockish b16 dynos, i can't wait for the day i get to dyno mine

 

Neato test. When I had auto B16 cams and a stock manifold I was making peak power at about 7100rpm.

I see you have that weird "b16tq curve" down from 3000-5000rpm. Mine does the same from 3500-4500rpm.

 

PM me if u got an AIR manifold layin around. i would LOVE to dyno it against an AEBS!!

 

TTT

lookin for manifolds to borrow!

 

.....post the a/f graphs.

Those will show the supposed delta's.

What size injectors?

 

AFR will take a minute. i got them saved on the datalogger.

they got mildly richer on the GSr cams, and kep0t gainaing power all the way down to 12.5:1

 

I'll make you a new chip.

Your not getting enough fuel after 7200 rpms.

 

Im loving the blue bomber black bumper special. Total hotness! Good job

you retard. the hood is open. you can mount any sort of intake up and lay it in the engine bay for dyno purposes.

u must be a JDM h8tr, cause that intake came on my JDM b16

i had a fan blowing into the engine bay and one blowing into the radiator.

IAT's were no factor in the #'s
