Thought i would add, that my stock bore turbo 9.5 pistons would not clear oversize intake valves either.
I do not fault JE for that unless a oversize pocket is specified.

The zx14 intake valves run right to the edge of the cylinder at the outermost part from what I recal.
I didn't check but is there even room with the stock valve angle to go oversize on a stock bore without notching the cylinder for clearance?


Theres plenty of room to the bore. Thats not the issue. Its the side of the valve pocket at the deep part. He also thought the angle was off.

Got enough miles to do full throttle runs. Pump gas with 104 just in case. Logged AFR 13.8 at 11K. Pulls like a freaking train all the way to the limiter. There is horsepower everywhere but gets real strong about 8K. Good golly Miss Molly.

Jim, I don’t have the numbers yet but you done real good. If I get arrested it’s your fault. I'll be easy to find, just look for the old fat guy with wide eyes anda huge grin.

Come on Monday!

I know you mtr is modified, & the 14's come RICH fr the factory, but, Are you still in the negative numbers in the 9750-11k 100%tp range??

This setup uses a PCIII. It was mapped for a Brock's Alien head pipe. The motor is being broken in before final mapping. It’s not a huge surprise that it’s running lean. The AFR from the data logger was 100% TPS in second gear (that’s all the road I had).

The PCIII will be remapped Monday. At that time the ignition module will be tuned as well. While on the dyno the bike will be fed race gas.

I just wanted to relate initial seat of the pants full throttle runs. The untuned motor shows promise to say the least.

After you get your mtr mapped in at correct arf etc, I'd still like to ask if you were still in the negative numbers in the 9750-11k 100%tp range??

Got them,

Competition CNC Stage II head, 1mm os valves
LC @105/108
2mm over
CR approximately 14:1
Brocks Alien head pipe
K&N air filter
Straight VP MRX01
PCIII with ignition module.

No power gains from ignition module.

Max torque - 111.33 ft/lbs @ 7.7K
Max HP (corrected) - 216.20bhp @98760 rpm

Torque curve breaks 100 ft/lbs at 5K and remains above 100 ft/lbs until limiter.
Motor is extremely tractable. Horsepower and torque build smooth save for a large jump in torque around 3.5K. The engine is streetable though octane booster is a must, preimium plus 104 booster seemed to work very well. It would be a monster street bike.

Still in negative numbers in the 9.7-11K range. But that is static on the dyno. The stock map seems to be dumping a lot of fuel in the engine at high rpm.

Jim done real good.

Next step is larger throttle bodies.

Stock crank, not sure which correction was used. To be honest I didn't know there was more than one method. Do you have calculations for each method?

I'll be running the Texas Mile, maybe Loring this year. New to the venue so the bike won't be the limiting factor. I need to improve my launch and tuck. I have a lot to do to catch up with the bike's potential.

I used VP MRX01 on Jim's advice. The engine may have been detonating on pump gas. Since I don't have much experience with the engine I would rather use higher octane and keep the engine safe. This build was a significant cash outlay from my point of view. So I am protecting my investment by tuning cautiously, hence the high octane fuel. The results speak for themselves.

I was surprised; the dyno operator was surprised, only Jim seemed a tiny bit disappointed in the numbers.

Bottom line, Jim's stage II head works. This would make one bad ass street bike. For me its too fast for much street riding. I would get arrested.

There is more power in this motor.

MRX01 is great stuff! Makes good power in an all motor bike. You are wise to use the higher octane fuel. I melted a couple pistons running pump gas in a 14:1 (measured) compression engine.

Great numbers! She should be a runner!
