cam gears

[biskey77]

[size=3][font=arial][color=blue]putting cam gears on a 96 teg ls. have mods of I/H/E, pulleys and a few others. what pitch should i go with the gears. i was told go 4 degrees positive. i am going for short run HP not looking for high top end. thanks

When you tune cam gears to high or mid range, do you lose STOCK power in either the high or mid? Or do you just gain less in one or the other?

come to talk about cam gears, what should be done to my cam gears? i'm using jun3's with spoon cam gears, jun springs, honda #100 pistons with b20b block balanced n lightened, type r head ported n polished.

doesn't make the awesome power i'd expected. dynoed it once, only 132hp@6000rpm. after 6k power went down like crazy. can now rev up to 7500rpm.

what's the problem?

I have the diskette, but how do I show it to you? Injectors are of H22 VTEC Twincam, ignition timing 15, fuel pressure is normal, compression is about 10%, cam gear was at 108 degrees.

My mechanic say he messed up with the cam spec, the calculated 108 when the valve is not lifted. Actually, should be 108 when valve is at 1mm lift. He said this is the main culprit.

On coming monday, he's gonna tear the engine apart and rebuild the engine. I requested him to recheck all the main bearings, torque of conrods, crankshafts & etc, maybe it will affect free revving if its tightened too tight, right? He'll use the clay method to set the cams to exactly nearest to the pistons at full lift to optimize the power.
He said this is necessary because jun3's are very difficult to set, is it true?
Is it necessary to set the valve nearest without touching the pistons to actually gain the power of jun3's

Is what he's doing right?

yup, the int valves are bent. replaced it already. now the power is only 132whp@6000rpm on the dyno after reassemblying. Where did my mechanic screw up?

thanks tuan

thanx tuan. i'll go through what you've said. tell you the result later
