Alright, what are you guys using for clamps and coupler for over 30psi?

That's what I was gonna suggest too, but spendy...Vibrant has those too, so I'm sure you're aware of their existence...I totally want a full piping kit built with these. Badass...

Vibrant Vanjen Style Clamp System

Well, the new couplers and the Forge styles held alright today at the dyno. I had to back off of the boost though. I could only push them to 30psi gauge which ended up being around 27.5 according to the log. The clamps kept slipping when I tried to crank the boost up and I kept loosing tack when I blew off the coupler at the throttle body so I cut that out real quick.

Pretty good day though. I did roughly 25 pulls and bested with 590tq and 575hp SAE corrected at 27psi on pumpgas.

I'll throw the gorilla spring clamps on there and head back for more boost when the pumps change to summer blend Ethanol in a few weeks.

What kind of pump gas and/or how little of timing are you running to let you do 27 psi?

I was looking at getting these. HDi

or these would be cheaper. HDi

31.2 degrees at peak torque interpolated to 25.2 at 7000rpm on 91 octane.

18.3 degrees at peak torque interpolated to 22.3 degrees at 7000rpm on E-85

There's no way I can run 27 psi on our piss poor 91 octane here which is why I was confused.

What turbos on your street car again?

[J. Fast]

They're EVOIII hybrid. MAC Autosport is saying they're 20G's but don't think they're quite that big tho.

Something similar to the "bastard 20g" I presume.

Solid numbers, Jeremy.
