camgear = power

[jspec civic]

Hi ppl,

i have got aftermaket camgears on my b16b, can they be adj and improve power even though i got have aftermarket camshaft?

thanks

[dsp26]

do you mean "HAVEN'T" got aftermarket camshafts?

yes there are power benefits depending on how much overlap you can run and where in the powerband you want it set...

best left to a "performance orientated" mechanic... as setting these wrong can be catastrophic.

***EDIT***
i was actually just researching cam gear dial settings on the net and here is an interesting comment from skunk2 i highly agree with:
http://www.skunk2.com/cgi-bin/kb.cgi?&do=read&id=185%E2%8C%A9=



Our camshafts are aftermarket performance camshafts and can NOT be set in like factory camshafts. They must be degreed in for optimal results. Page 21 of our catalog, which can be downloaded under "News and Events" on our website, gives an overview on how to degree in a camshaft. We do not recommend using the cam gears to dial in our camshafts. In some cases we have "Quick Settings" using our cam gears that can set the camshaft close to a degreed-in setting. Using this method, however, will release Skunk2 of liability if something were to go wrong such as engine failure because degreeing-in the camshaft is really the only way we engineered the product to be installed. We recommend that professional mechanics familiar with "performance tuning" of the specific vehicle in question install the camshafts. Many mechanics are experienced professionals but the camshafts that we offer deal with much newer technology than what most seasoned mechanics are used to.



like i said in another thread and most will agree, i refuse to take my car to your everyday mechanics when i know theory/consequences far more than most of them despite their years of experience with (dis)assembly exceeding my own... there are however outstanding examples and you would normally trust them as you've dealt with them before and understand the level of their expertise.

great find!!
some dam helpful info in there

[todaek9]

Hardly saw anyone can dail a cam at all...if u find one, pls tell me...but not those "who use dyno and dail (retard or advance) a degree at a time"...

[grumpy rooster]

I know someone. :)

And I know someone who can't.

[dsp26]

I know someone. :)

And I know someone who can't.

I wanna know too... does this person happen to be in Minchinbury? :p

[grumpy rooster]

Yes. I have first hand experience with him in before and after dialling in of a cam. He had to fix what someone else had done on my car. And this was another reputable tuner who was supposed to do it but had it all wrong.

[todaek9]

I got mine done...before and after effect was just crazy if your dail is perfect...but it was the best 3-4hr i spent waiting and watching plus i have no idea what kinda things he's doing...And the bill is quite dear...

Ppl with cams should get it dail using this method, but not some crappy "a degree at a time" and yet not getting it perfect...

[beeza]

What meathod is that Adrian?

[kraiye]

dont you have to pull the head off or something and use special tools to do it right?

[dynosaur]

I know someone. :)

And I know someone who can't.

can u tell me who ?

I m located in Melbourne .

thanks alot :)

[grumpy rooster]

I only know Sydney well.

Go see Andy if your in Melbourne.

soooo... i came across this right (v2v & p2v clearances):
http://honda-tech.com/zerothread/1891614

Will/Should a tuner know my exact cam specs and lash adjustments prior to them screwing around with an assembled motor on the dyno?

Also is anyone able to tell me how much retard b16a2's suffer for every 1mm removed from the head or headgasket?



Seems i may have to mill the head a tad if it's warped which doesn't help me as i've commited to a purchase of a 0.5mm head gasket which i intend to use. This obviously won't leave me much room to correct cam timing retard + overlap tuning of my cams as v2v will become the bigger issue... didn't realise clearances were so tight on honda motors:zip: Until someone can give me an answer on this also, am I safe to assume I can remove UP TO 0.5mm off the head and use the 0.5mm head gasket because the pr3 pistons have valve reliefs?

I will most likely be running Skunk2 TUNER Stage1 cams with Toda springs i've acquired... seat pressure research tells me that it will be able to seat the valves properly at high rev so no prob there.

[dsp26]

actually.. is anyone able to tell me how thick the standard AUS B16a2 head gasket is?

according to:
http://www.c-speedracing.com/howto/compcalc/compcalc.php
the OEM 3-layer HG is 0.7366mm/0.029'

i maybe able to workout the retard based on this:


note how about every 2 degree increments = .020 thousandths difference of clearances. therefor every 1 degree changed on the cam gear = .010 change of P2V.

i think you should leave all that to your tuner/engine builder..

i'll be doing it myself :) + help from willing forum members.

a pride myself in my own work... don't see the point in modifying a car or being an 'enthusiast' if i can't do or attempt certain bits myself.

doing this will be my first honda but not first engine so i'm a tad n00b... i'm willing to risk to learn :thumbsup:

that is how people learn. Good to see you putting in the effort and researching before taking on the build.

People seem to throw cash at workshops and expect magic to happen but in the end they get disappointed and ripped off.

ok good on ya mate much respect goes to you for attemptin it yourself.... i just thought your getting it built and i was thinking that you should leave all that stuff to your engine builder etc... sorry for the misunderstanding all the best of luck

[dsp26]

^^^all good.. i was just hoping some speople already had measurements of sorts as it helps a lot in the pre-planning stage and predicting what other supporting mods i would need in advance.

[Limbo]

i had Hanny's preinstall & adjust them when i got my timing belt changed.

i have to say i certainly felt a difference & they ddn't charge any extra for it

[Limbo]

There's a standard setting for stock motors i just can't rem what it is.

[dsp26]

cmon Limbo use the force!!!!

considering some info you started releasing in the water leak thread.. would you mind telling me how much you shaved off the head considering you have high lift Toda Cs? it'd give a good indication of available clearance

[delsol9000rpms]

not sure mate sorry... the toda spec c's have 12mm lift... i think it was about 20-30thou
