Situation: The shop that can degree the motor is stupid busy and wont be able to degree my motor for a month. Ive talked to my tuner and he said if I can get the base cam gear settings with the amount of adjustability he can tune the motor. (example would be +5 exhaust, 0 Intake with adjustability of +/- 1 degree exhaust and +/- 0.5 degree intake)

I need to know The Base cam gear settings adn adjustability!!!

the setup is b20vtec
12.5:1 compression ratio
skunk2 pro3 cams
rs machine pistons
ferrea valvetrain

So if there are any pro3 guys please let me know! Or even better if there are any skunk2 personnel to help me out even better!

Ive been trying to find it all over and cant find ****. Ive been trying to call skunk2 but can never get through and all i get is "there is 1 caller ahead of you" BS then leave a message after 10 mins of waiting....

Help a Brotha out!
Thanks HT

 

I have new pro 2 cams and while the standard response everyone would give you is that the cams need 4 degrees of separation to be safe, I only need 1 cam degree of separation to get .040" clearance V2V. I only know this because I took the time to measure the clearances. If I had of just asked what to start my cams off with and tune them with from people on here, it's possible my final gear settings could have been far from optimal because of the amount I was told to seperate and adjust. My advice to you would be to either degree the cams or at least measure the V2V clearances so you'll have a much better idea of where to set the cams and start tuning from as far as clearances go.

 

yeah, just got a hold of a s2 rep not too long ago.. they said 4 seperation as well.. **** im gonna try to bribe my degree guy to squeeze me in.

any other input?

 

In for more advice

 

there is member here that goes by the name of 92TypeR that did it on his set up and he kept it 5 or 4 degrees apart and made good power

 

my pro 3's are straight up on the intake and -4 or so in the exhaust

 

i dont know how accurate this is in real life.. but the skunk2 rep told me what they have written in their books is +2 intake, -2.5exhaust.

i talked to my degree guy, and he said thats about what they come out too.. +2,-2 he said.


more input would be great as i would love to race my car as i live in canada and winter arrives pretty fast.

 

bump this up!

so would it be safe to move my settings as i tune?
like start at +2,-2 1/2 then advance 1 degree each side to get it closer to right angle?
there is about 30 thou taken off the head and block combined, i heard the golden rule is to advance a degree on both sides for every 10 thou. which will leave me at +5, +1/2

any input on this??
thanks

 

you wont know what settings make the best power on the dyno w/o making several adjustments

and you cant safely make adjustments w/o first checking your clearances

 

This ^^

and...you only advance 1 cam degree for every .040" removed.

 

in this 4 degree separation does it matter if it goes - or + ???

 

if your looking for the drop in settings for the pro3's, they are the same as the pro2's

0 on the intake +4 on the exhaust.. if your gears are setup for 1 cam gear degree = 2 crank degrees, use 0 on the intake / +2 on the exhaust.

 

you sure..? you didn't mean +4?

your motor would have imploded.

 

im using the GE gears..and thanks for the info

 

Sorry to bring this back from the dead.. But my H22 pro3 safe zone is also..

0 intake & -5 exhaust = . 030
1 intake & -5 exhaust = . 035
2 intake & -4 exhaust = . 033

Etc..

+ 4 on the exhaust is a definately NO zone...

Using the Skunk 2 pro cam gears.

 

I believe your numbers are backwards. Please recheck. This was V2V?
There's no way that your intake is @ 0 and your exhaust is @ -5 and you didn't touch valves.
Advancing the Exhaust will reduce chances of V2V contact, you're seperating the cams from each other more. Please make sure you're calulations are correct.

I'm almost 100% positive that you mean to say

This is +1 intake & -5 exhaust

 

are you 100% Sure you have pro3's..?
Just have a hard time believing this, as everyone has to have some seperation, you're just bring them closer, Did you degree the cams yet as well?
Please make sure you have the proper Pro3 markings on the dizzy side.

 

Yes they have the 'P3' markings..

 

Did not degree them yet, just checking my v2v clearance

 

Amazed that you have that much clearance. I've done a few h22 setups, the best settings while having the minimal clearance of .030 was a -1 intake and +3 exhaust.

Good luck!

 

So +4 exhaust, will do what? Hit your intakes? How is that NOT a safe setting?

 

I find it also weary myself, Ht member 93-lsvtec-eh2 also has about the same as me.. - x on the exhaust side..

But you and others have + on the exhaust... I wonder if the '-' and '+' markings on the camgears are ok..

 

Check to see that the - is towards the back side of the Gears, and the + on the front side.
It should look like this.

I too am also worrying if they were stamped wrong. Advancing would be going in the direction of the rotation of the motor, Retard would be going in the opp direction as rotation. Normally if you're retarding a gear, you're pulling it back towards the firewall, if you're advancing it, you're pushing towards the front of the car. This is from looking on the side of the car @ the gears themselves.


Its very hard to see the marks on your gears from the picture.

If all checks out, then dont worry. You've got actual clearance checking. Can't dispute what you have infront of you. Good think you're doing what most dont. Good luck again!

 

Well this explains it!!!

My + marking is pointing to the firewall and - to the front!! Ain't this a b$&@!!

At least we know this now!!
