New vs. Old


AFR + Boost

 

damn good numbers

 

You're making a lot of torque

 

That's pretty wild, 44hp from 1psi
Maybe the venting of the crankcase pressure had desreased resistance on internals along with whatever caused the increased boost numbers??
Wonder how you netted that extra 1psi?
Was it just a fleeting 1psi or do you get better spool up accross the range?
Got anything to compare spool up rates with? Do you have a wastegate /boost controller switch?
Did you get and more boost just off the wastegate setting choice?

 

Yeah, I'm pretty certain that my crankcase was seeing some big numbers pressure wise so it's definetely not working as hard for what it's making. The engine feels healthier too.

My boost is pretty wild right now. It's a combination of my electronic boost controller, the boost reference locations and the improper A/R turbo housing.

Here's a boost graph of my previous pulls on the dyno when I still had the PCV system... (Green line)



And this is a boost graph with the crankcase vented to atmosphere... (Green line)


Looks like the spool up is similar and I still hit 17psi at 3900rpm's but doesn't choke down as quickly as it did last time and carries a little further before it dies back down. It's also only dropping down to 15.5 psi at 5500 rpm's instead of 15psi @ that same RPM. I know my A/R housing is choking the turbo down as I get into the mid 4K range but not sure how much of that is due to the boost controller.
As of now my boost reference is done in two places, the intake manifold and the turbo outlet. Not sure why it was set up like that but it's causing some fluctuations in the boost and I can hear the waste gate opening way before I get into full boost. So I'm hoping once I plug the boost reference in the turbo I'll see boost a little earlier.

 

Oh and I haven't touched to wastegate setting it quite a while, it's pretty much set to Wide open when the switch is on high boost.

 

I think you touched your waste gate too many times buddy (sorry, couldn't resist )

 

I am so glad more and more people are using the Dynapacks. Now I can keep up with the dyno sheets.

18psi and no meth . how do u do it

 

big cam, low compression and no timing.
