HA HA HA
Charlie did you read the beginning of this thread? You were going to boost to 15 psi. LMFAO! 30 and climbing. I guess that might happen to me?

How fast has the engine run? Any comments about vibration levels?
I've never built a 'four' before, but I'm working on one for LSR and am concerned about the inherent imbalance (180 degree crank)- don't quite know what to expect at 9-10,000 RPM.

There is a pretty wicked vibration with this engine. The only thing I can say about it is it seems as the rpm's go up it appears to stabilize. I.ve had the valve cover bolts come lose , the starter bolts too. The only real time I notice it is when I'm cursing. The rear view mirror gets burry . This motor see between 6500-7500 at the most. I think people make it out to be worse then it really is. I know of a couple of guys that spin this same motor to 8500 rpms all the time and it lives. So 9000-10,000 I don't see to be impossible . Just get it balanced real good with light parts...

Thanks Charlie. "good balance" can be done. "light reciprocating parts" no way! Hemi pistons with domes to get to 12:1, and Diamond-recommended full-skirt (not those 'skeleton' pistons that guys run) to survive 30+ PSI boost and 4 HP/c.i., on BME 426 forgings- not at all light. The only factor in my favor for less vibration, is the decent R/S ratio of 1.84 (6.660" rods, 3.620" stroke).

No problem Jack. If there's anything else you want to know feel free to ask. I've been through a lot with this motor. lol There will be a lot of fabricating for sure...

Innovation for speed at Bonneville is the nostalgia. Twin balance shafts can control the 2nd order harmonics.

I finally got the header installed and the motor running. I also have 3/8" pushrods in the motor now. That wasn't an easy task to do.. Now I have to get it tuned better it seems like the new header wants to have a little more timing at idle. I haven't took it out for a ride yet but im betting in going to have to make some more changes there too. This fuel injection is not easy for me so far.. I have a lot of respect for these guys that now how to tune them...

Charlie,
I just noticed your front stabilizer bar setup. It looks like a "bolt-in" deal. What is it and can you show photos of how it is attached? Thanks! |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
