395 int/378 ex..... HELP!!!!!!

[jcq225]

I built a gen1 1441 and im getting all kinds of degree numbers from friendly advice.My question is has anyone ever had this cam combo and and actually had good results!, what was the best degree for these cams.....please no rocket science mumbo jumbo ...keep it simple

[busaman]

first off neva write in red....got a headache trying to read and im sure everyone is going to chime in on this.....good luck man

[popeye]

depends what your setup is. 110-111 or 105-103

its hard for me to being willing to give you any lobe centers to use, simply for the fact that i didnt build the motor so i dont know things like the piston to head clearance. so i was to say run it at xxx/xxx and you didnt check the valve to piston clearance then tap the valves on the pistons, you would be pissed at me like it was my fault...and its hard for me to give this information with out getting into rocket science mumbo jumbo. i think the safe answer for your build would be do what web camshaft suggested off their tech card lobe centers 106/108 and adjust cam timing if needed to have at least .060" vtp clearance on the intake and .080"vtp on the exhaust. it this is too rocket science mumbo jumbo i would advise you to have a professional builder time your cams.

I agree 100%

sorry about the color didnt know it was red,I do understand what your sayin,but my original question was did anyone ever have this combination and what was your reference degree point that made good power.108,110 and I have good ptv clearence,I was wondering about closing and running tighter cam degree

tighter? are you wanting more or less valve overlap? which ever way you go, in theory, will move the power curve lower or higher

[slo poke]

I have 395/385 and I tried 108/110 but I noticed the power band moved upward and shift point changed slightly shifting at 10600 so I went back to 106/108 or but now I run 105/107 shifting now at 10800 my bike seems to to love that setup 1441 gen1 motor I was told I could raise my rpm a little more if I do the ecu mod but I just ain't sold on that just yet

[jcq225]

I have a computer mod already done ,but remember it does not matter how high you can raise your *******,because if your not in your power band then your loosing HP...dyno will tell you where your power band is and shift within it.

[slo poke]

I know that as well so i didn't do the ecu stuff i like mine the way it is.

[Iwannagofast]

So you shift it on the limiter? The limiter is set at 10,800 from the factory.

[knecum]

so why is your fonts still RED?

[slo poke]

I shift at 10,600 actually but can do 10,800

[BRUNOSBUSA]

As far as the cam degree #,s I run different lobe center lines depending on if it's a all motor , nos bike and depending on clearances. And I don't no where exactly the factory rev limiter is on Busa but I can tell you I shift at 10,800 never hit the limiter with stock ecu .. So I be willing to bet the limiter is a few hundred rpm higher than show on the ************** of tack..

[Johnnycheese]

so why is your fonts still RED?

because they are like everyone one else looking to make there bike fast and won't help anyone else
