Uh, the M21 is a turbo cam...

M22X's are what you want.

 

Aquafina, will I need any other headwork, such as a P&P to run the M22s? I'm definately considering them. But, then again this will be a daily driver.

Bump

 

Nope, you can drop them right in.

 

the duration on bc3+ is like 295 or so but not 300

and we dyno did a bc3+ cam test on an all stock b16

stock 135whp
stock with bc3+ 145whp
stock with bc3+ and Intake cam gear +2
152whp

stock with bc3+and intake cam gear +2 and jdm itr (runing open header) 165whp

these r on a dyno jet

good ****!

135whp stock to 165whp bc3+ + gears + tuning. 30whp....thats very good.

WASN T TUNED
ONLY CAM GEAR ADJUSTING
DIDN T ADJUST AIR FUEL OR TIMING YET

 

Hrmmm, how much more power can be squeezed out by adjusting the air fuel and cam timing?

from the looks of air fuel
not much more peak maybe about 3-5 with timing adjustment
but mid range will be a very big gain!

 

From what I've seen B16's don't like much cam. Much more than CTR's and your spinning the bitch to 9.5k before the good power kicks in.

Look at Omni's 200whp B16. Peak power was at 9.2k rpms with a profile similiar to TODA' Cs.

thanks 4 the heads up

 

UPDATE:
I went with the stock injectors for now until the break in is finished for tuning and BC3+ because of the sufficient mid range in consideration of an already acquired T1R 4-2-1 header, prescribed compression ratio (CR) in correlation to the motor's approximately 10.8:1, smooth idle, advanced chill casted design technology, availability and affordability.

If I would of had a slightly higher CR and a 4-1 I would have definitely gone with Rocket's m22 cams. Only downside of the BC spec 3+ cam is the profile, the duration is a bit on the large side for a B16.

Until the next update or my next post, cheers damsels and gents!

 

Well we just got done dynoing a stock B16 with the smaller old spec m22's and they picked up 7-10whp throught over a big name brand

 

what were the cam adjustments over the major brand? What was the whp?

 

Let me try to get the dyno and more details re the tune.

my STOCK BLOCK and unported Head b16 made 170whp with M22s. all i did was install omnipower valves, .10 mill, m22s and AEBS manifold.

baseline was 146whp

 

suscribed!

 

Cant wait to run my M22s

how much compression do you pick up with a .10 mill? I want to run M22's but not sure what combination of things to up the compression...

 

How much do you have to rev a B16 to make good power from M22? Since M22 has 12.1 lift the BC3+ seem better for a daily driver who doesnt want to spin a bearing?

How is the primary and secondary lobe between the two cams?

 

to me it comes down to Billet vs. Chissled Cast Cores, Billet wins so Buddy Clubs all the way
