Yeah, rocker arms on the hydraulics...

Re: Twincharged wagon is hitting 30 psi!
 

Could you have a valve which is slightly sticking open. Or a hydraulic lifter which isn't properly taking out valve lash (and not fully opening the valve), causing both the ticking and the lack of compression?

Anyway, that thing is utterly badass. Apart from the new paint job.

I say do the bottom all red then the from the bottom of the glass on up do all black. Not feeling the new ummm paint job your rocking right now. :-\

----, my grampa's antique 41 ford flatbed w/flathead is running compression like that - for the 60-something octane listed on it's specs plaque. :S

I'm curious how much that thing weighs. Mid-12's with 30psi and awd, must be tipping 2 tons?

Re: Twincharged wagon is hitting 30 psi!
 

The wagon weighs in at 2700 lbs.

Finally am in the 1.7xx 60' time.

Because I have yet to get the SC to switch off, and then be bypassed, I am leaving 30-50 hp on the table.

Also, because I am such low compression, I am probably needing to up the boost a bit more..... But only on a dyno for safety!

I have some of the parts for the SC bypass valve, but still need to gather the right solenoid and so forth...

Re: Twincharged wagon is hitting 30 psi!
 

And its official. 30 psi is WAY too much for the shitty SPEC pressure plate. I was finally pulling 12.5 sec 1/4s at 112 mph, and the clutch started giving out everytime. :(

Re: Twincharged wagon is hitting 30 psi!
 

Boost was well over 30 psi today, but kept having either clutch issues, or running rich and bogging in the top end. When it ran well, it ran swell though. Couple of 12.6 @ 112 with crappy launches.
