Green is a stock f20c
blue is my built motor on stock cams (2.2 liter, 12.5:1 compression with boltons)
Red is built motor with brian crower 3 cams, dyno'd back to back on the same day



There were no timing chain or clearance issues with these cams. I am using supertech dual valve springs.

all 3 setups were fully tuned with aem ems.

 

Goes to show you how good the stock cams are.

 

hmm.. wrong attitude.. lol, it goes to show how BAD aftermarket cams for this motor are. ( or at least these cams)

 

maybe the tune?

 

wow i would be upset, maybe do some more runs on the motor after letting it cool all the way down.

if nothing else, i'd call them and get my money back.

 

wasnt the tune, jason spent a few runs just getting those cams back to where he was making power with the stock cams, and then a few more to get that 5whp peak gain.

they arent his cams so no worries about getting his money back

 

sucks for whoever owns em

 

lol, whats the price on those cams for 5whp? lol

 

In a couple weekends are are going to be testing them in the owners car.

he has an AP1 with a short intake, megan header and i think he has a 3inch exhaust

 

That's true I guess, I wonder how bad the stage 1's are?

 

These results are not surprising. Were there any cam timing adjustments made?

 

no cam timing adjustments.. I'm WAY too Poor to spend $800 for a set of cam gears.

I have a set of Brian Crower stage 2 cams on the way and i'm in the process of making a new intake manifold.

with the bc3's there was more than 1psi of vacuum in the intake manifold past 7500 rpms.

 

I tried the BC F/I cams when they first came out (it was the first set to be installed) and the results were 7hp less than stock cams.

 

Did you ever get a chance to dyno them with a F/I setup?

 

Yes , that's how we know the hp diference.

 

BC cams seem to have the same results on many platforms.

 

Let's just give it more lift with less over-lap and call them F/I cams. Sadness

 

How were you able to degree the cams without adjustable sprockets? Don't the cams come with a spec sheet explaining how to set proper cam timing? Pretty sure any high lift/long duration cam will need to be degreed to specs before working properly.

Also how much total advance are you running up top? My stock f22 made 227, could just be a bad tune. Or just very conservative.

 

the guys i talked to at BC said they should be fine w/o adjustable gears.

with the lack of adjustable gear availability for this motor its stands to reason that they would take that into consideration. the ONLY available set for this motor is the Toda set at $800+

I have a set of stage 2 cams i'll be testing in 2 weeks once i get my diff put back together.. stupid honda and their glass rear ends

 

Just seems strange to me. Every aftermarket cam I've ever bought came with a spec sheet and recomended cam timing.

 

they do include a spec sheet, but there is no way to change it so noone cares to be honest.

this graph is in MPH, we were having tach pickup issues

vtec is at 4200

 

Was looking at the wrong graph haha. Didn't ips offer an f20 cam? Or was that just in development?

 

any reviews on the s2 bumpsticks
