Get a smaller pulley you pussy.

 

+1 agree

 

To those of you who have installed these keys have you tried to run with the stock ecu for inspection purposes ?

 

I think that's pretty close to the gains that were guestimated for that power level. Also, thats still good power/$.

Due to my low compression and high flow heads, I failed with stock timing. I then retarded the intake 2 degrees and passed.

 

Eight horsepower is a positive outcome. A little lower than I expected but positive.
Every engine is a little different and thus results will vary.
Anything you do to add power now will add a little more because of the cam timing change.
Little things like more boost, bigger exhaust, better fuel.

How much tuning was done on the dyno? Was fuel added? Was the tuner being safe? Is there a plot to share?

 

I don't have an overlay with me at this moment in time.

It looks like there were no any gains until after 7600rpm even then it was around 2BHP, up top at around peak is where i noticed small gains, even then it may have just been due to the fact it leaned the mixture out a little (from 11.7 to 12.1 AFR) so the cam timing 'could' have done nothing. The belt was slipping slightly at the top end at the power was originally down from when i was last at the dyno, it was tightened and power shot up.

I did advance/retard the timing slightly with no gains in power so the timing was pretty much spot on with the cam keys and before. I am the tuner.

I'm not sure what went wrong really.

 

It sounds like it made positive improvments

The fact that it made the afr leaner shows that the engine is breathing better as a result. I think it’s safe to say that if you were maximizing the pressure from your blower, that you probably would see your current gains two fold.

At my level I’m really interested to see what gains I would make. I'm making nearly 16psi at only 8k rpm. After all my efforts getting my car back on the road and running good, I am leery of performing this operation though, as strait forward as it is. I dont like the idea of undoing the head bolts. hg failure scares me a bit running my pressure level and injecting water/meth.

AJ did you see any difference in boost pressure measured after this? More? less?

 

Please explain...

 

In order to pull the cams, you have to pull the tree unseating the head, therefore head gasket failure seems more likely then leaving the motor un cracked. It makes me nervous considering the cylinder pressures I’m already running. It may be undo worry, feel free to put me at ease.
