hey all, ive been a long time reader and huge fan of the site, but this is my first time posting

my question was:
to everyone running skunk2 pro2 cams in a b16 i was just wondering what everyone had their cam gears set to?

i know.... i know.... i should degree the cams in, but i just want to be able to start the engine for initial cam break in then its going straight to the dyno for a full tune

the last thing i want is to smack a valve in this thing as soon as i fire it up!

it is a stock unmilled b16 block and the head only had 3 thou takin off at the machine shop (wasnt warped, i just wanted a perfect sealig surface on the head)

like i said this is for initial startup only.... im not expecting it to make peak power with the specs you guys give me, i just want it to be close enough to safely run

thanks in advance

You do know that pro 2 cams are big cams right? You realize that they'll probably make peak power around 9000 Rpm? How is the rest of your build designed around those cams?

 

the rest of the build is fine.... just wondering if anyone knows a safe gear spec for initial start (i want a safe break in, not power.... itll be on the dyno for that)

 

Doesn't Skunk have "quick settings" posted on their site or on the literature that comes with the cams?

 

X2, they should have all the details on their site.

 

In a B16, try more like 9500+

 

+5 on th exhaust +1 on the intake.

 

Why would that even matter.. The cams will only make so much power depending on the support of the motor.

I shouldn't have to tell everyone here, that these cams will make power in a b16.. even the pro3's.. it wont be "opitum" power.. but it will make alot of power.. you just won't be able to ultilize it.. until you can support the revs and flow.


and dont say compression.. its only 1/10th of the equation.. to make power..

Your exhaust on the pro series cams will always be more advanced, then your intake.

 

thanks ALL MOTOR

are those the specs skunk has listed on their page(i cant find them)?

 

These are specs from multiple professional guys.. that have used and tuned these cams

e.i. donf for one.. those settings help?

 

For my pro 2 build

When i degred my camshaft +4ex+2in was the peak lift on each vtec lobe.

But my v2v clearance was fine also with these skunk2 quick setting +4ex+3in

 

Funny how a B16, B18 and B20 have way different torque/hp curves with the same compression/cam. Almost like displacement plays a part in it....like a B16 makes power higher in the RPM band then a B20 w/ the same compression/cam. Um...I might be on to something here. Next thing you know I'll be saying that nitrous adds 200ft/lbs at 2600rpms but only 50ft/lbs at 10k....um....again, must be on to something here.

 

displacement Is the part that makes the difference. a perfect example would be why diesels engines make their peak power around or before 3000 rpm. the stroke is so long it can only turn so many revolutions per minute. look at a rc car engines for example they max out around 40,000 rpms only because they have such a small stroke. train and ship engines have mass amounts of hp but use huge two stroke engines except the locomotives use the diesel engine to power generators that support the electric motors which put the real power to the wheels. we could talk about wacky RS ratios all day but i been drinking so i will get my as$ to bed before i wonder off into a drunken stupor. have a nice day man

 

?

you need to clear up some info before you spready it around.

b16's ya..

b18's ?? Gsr or ls..

B20? you realize that a ls and b20 make more torque then a gsr and b16?

Pro1's make power ona b16 up to around 8300rpms ona dynodynamics making alittle over 136whp on those dynos.
Pro2's aren't that much bigger on the primary side, where its bigger is the vtec lobes.
Point of my reply was.. you said its a b16, i said why would that matter because this isn't the right cam anyway for his setup.
the pro2's shouldn't even be used in this setup if you want to make optium power.. you can use them.. you just wont be able to rev as high.. as you need too.

 

95 integra... you do realize the b16,b18,b20 have different RS ratios? different displacement? the torque curve and hp curve are not determined by the compression of the engine. from what i know, when talking about engine powerbands you have to consider the size of the engine (bore and stroke) along with the camshaft being used(thats if a camshaft is being used) and rod stroke ratio. the powerband is said to be between the peak hp and peak tq. but i would not say the cam determines the powerband. although the tuning around the cam has a lot to do with how well the cam will perform in certain platforms. the example i was trying to make last night would be smaller engines make their peak power at higher rpm than larger engines. no real mystery there. they just operate at higher engine speeds. its like you were insinuating something but didnt really get into anything specific. hopefully this cleared up what i was trying to say last night while being intoxicated.

 

u do kno u need to run aftermarket valve springs n retainers right?? juss askin didnt kno wat else u got done to the head!!? i got those cams i had to get skunk2 springs/titanium retainers

 

did you ever get the b16a dyno tuned? what settings did you end up with on your cam gears?

 

just go +1 in and +4 ex

 

Does anyone happen to know the p2v clearances at ex +1, in +4 with factory sized head gasket and oem pistons - assuming that the head has not been milled and the block has not been decked?

Thank you!

 

Sorry, I should clarify - I was asking in regards to a B18C1 GSR engine.

 

you'll have to measure as it varies. It's more about it being in a safe range rather than a specific number.

 

sorry to bring this back but when u guys say +1 in take +4 ex r u talking bout degrees or marks

 

degrees. some markings on cam gears equals 2 degrees
