on the h22 how much power are people making on the pro 3? any dyno graphs links to other builds with the pro 3s? what advantage are a web or ferrea cam profiles gonna have over the 3s? is it in the rocker arm design? thanks for your help in advance

 

i have a set of pro3 cams in my car right now. im gonna re-tune the car sometime next week and will let you know how it goes..... BTW the car sounds wicked while idling

 

look at NAH2B. He is using the Pro3 cams on a stock port head. Like 13:1 CR and an f23 crank made 305hp IIRC with a burns spec header and a custom made intake mani.

 

NAH2B is running a 95mm crank. I doubt its a h23 one either. he also has a rlz valve job on the stock port head, race gas, etc.....

 

Yes, NAH2B is running 89 or 90 bore with 95mm crank.
I am running PRO3's in my DOHC F23. Will have dynojet numbers soon. Idles like a V8.

 

actually it is a new h23 crank

heres a link to his build thread. unfortunately its closed a quite a few pics missing but you get the idea

https://honda-tech.com/forums/drag-racing-36/build-thread-import-sports-street-allmotor-h2b-2474967/

 

yes sir...94+ crank

 

cool thanks for the replies.. but what about other customs grinds from web or ferra? any advantages 4 those?

 

See signature for Pro3 power.

 

Whats your supporting mods, and reason for this big *** cam..?

 

well my setup currently is about 2.4l fully ported head dual 55dcoe weber carbs custom header 15..1 compression debating on pro 3 or spend the extra on a set of web cams.. is the extra money worth it for the rocker arm design.. how much horsepower realistically will you gain over the pro 3s.. i sent 3 different cam sheets... majorly different to web cams and they sent me the same profile for each build.. that is why i ask. doesnt seem to accurate to me.

 

Well ever motor responds differently to any upgrade done.
You obviously have a full out race motor, so i'd look into some custom grinds.. pro3's could provide you with what you need, but at the price, you could probably get some custom grinds from bisimoto.. or rocket.

 

here ya go:



as others have said:

89x95
13.5:1
custom intake and exhaust manifolds made by ME haha

very simple and reliable engine setup w/ plenty of room to make mo powa!!


if your gonna run the pro 3s make sure you learn how to do this:






or you can pay me to do it for ya

custom web cams could be an advantage if you want to run os valves.

however you may be able to get the pro 3's to work w/ +1m oversized but you will have to pull them away from ceterline.

i will find out soon

what is your setup ad what are you gonna be doing w/ the car/motor?

 

what cams r u running now?

 

well pro 2 now in the current setup.. other engine is itching to go in... as far as degreeing the cams in... not a problem but thanks for the offer.... as far as changing the valve timing events to run oversized valves, how will you know that your not hurting performance? skunk 2 says to open and close them at a specific time for a reason...

 

screw what skunk 2 tells you lol. skunk "says" alot of things....

seriously though you can certainly lose some power by "un degreeing" your cams, however the advantage of runing larger valves in an H head will outweigh any possible loss.

my cams are off centerline now just to have .032 V2V, otherwise would have only had.028 with their specs.


do you have os valves in the head already?

and you said pro 2s in your current setup but sounds like thats a different motor. have you run the new 15:1 motor yet?

 

which is why degreeing the cams isnt a priority....

but knowing your clearance is

 

have not run the new engine yet.. no on the oversized valves.. who does your head work and can put in oversized valves?? what did you change to make your v2v different?? did u see a gain?

 

i dont have any headwork yet other than the infamous RLZ valvejob performed by the best man in the industry himself.

when you change cam timing, your changing V2V and P2V at the same time.

dont worry about gains and losses from cam adjustments so much. just know your clearance limits first. then you can "play" w/ them on the dyno if you want.


so when you ordered the 15:1 pistons in the new build, what cam specs did you provide while ordering?

 

well i had web send me a profile for it.. if you want specs i can pm them to you but i need to get the card from work.. what about the valve job is so special?? and how can i get ahold of him?

 

and where did you get your dial indicator setup from? its badass. i use a single one and have to swap side to side

 

radius valve job w/ magical angles haha

best way to reach Brad is email www.rlzengineering@yahoo.com


nah i dont need the specs

take those specs and compare them to the pro 3, most likely you wont be able to run them w/ those pistons but you never know....

 

jeez you want me to give away everything huh?

lol its all good, its the Belben kit. available from Xenocron in NY. get the degree wheel w/ it. saves alot of time from doing backwards math in your head

 

well its a locked vtec setup so im not that worried about cylinder pressure being too high since the duration is so much on the pro 3s.. as far as you intake setup is it an itb or plenum manifold? and what about your runner, is your intake port enlarged or stock size?

 

im talking about P2V clearance, you may not have enough. takes alot of dome to get 15:1 and depending on the rest of the bottom end setup and the cam specs you gave the piston manufacturer you might be limited to that cam spec as a max.

my intake setup wont matter, its nothing like a set of webber carbs haha

but theres plenty of info in my build thread which someone already provided above if you want to look.
