In a way I hope you do infact had the 145mm crank.It will show the reliability of the blower/kit even with the 145mm pulley.
You have had your kit on almost as long as William has. 1.5 years with a 145mm crank
If you have the 145mm you absolutely need to get up to Huntsville so we can get it on the dyno and get some numbers It will be free for you even if I must pay for it myself..
Now where did that damn 145mm pulley go again???

[QUOTE]neptuner.
Has your boost always been this hi.....Yes. Have actually seen peak as high as 11.8 psi
I remember you asking about it at TPGR SESM last year but I don

Put it on a dyno and see if your boost gauge/MAP are accurate.

The idea that valve timing could cause this is interesting. I have adjusted the valves before but the valve timing has never been intentionally changed. In fact, the head has never been removed so I expect that the valve timing is the same as when the car left the factory.
Has anyone experienced or heard of valve timing being off and causing higher than anticipated boost pressure?

I get 10-11 psi with the 135mm pulley I was getting 6-8 psi with the 126mm pulley.
I think Neptuner's kit shpped before I had SOT build the 135mm and 145mm pulleys for me.

using camuman's (AP2 ) My (AP2) and WLAURENT (AP1) comparable supporting mods/setups
On the 126mm
AP1= 6-8 psi
AP2= 5.75-6 psi
135mm
AP1= 10-11
AP2= 7.5-8.5
142mm crank
AP1= who whats to try it
Ap2= coming soon
Is the differences between the AP1's and AP2s displacements and cam profiles making that big of a psi difference....
I need more data to say yes but the data so far points to yes.
But that still does not explain why Neptuner's psi is so hi.
based on the numbers above he is runnign about 2 psi higher then expected.
