What do you hit for max boost and exhaust back pressure?

I have my Turbonator set to limit boost to 55psi. EBP is also at 55psi at that point.

Are you running head studs? Any valve spring/pushrod upgrades?

Yup. ARP headstuds, fire rings, Mahle pistons (coated), Manley rods etc. need to look up pushrod and vave spring specifics.

Thanks, I installed a turbonator VGT (not the electronic one, so I cant set limits) and I am trying to find out my "safe zone" I have ARP head studs (not fire ringed heads) and stock pushrods/valve springs. I hit 50 backpressure and 38 lbs of boost. Before with just the SXE364.5 I never really hit over 40 psi on either before.

I only really have a few reference points with the VGT, that's you and backwoods

I have been following along on your build. Looks like you got the Turbonator set up well from the get go. It’s not hard to see high EBPs when those vanes shut. I think they’re capable of cutting exhaust flow off more than the original EBPV. I don’t know how responsive your mechanical actuator is to throttle lift though. The electronically controlled actuator shuts the vanes pretty aggressively when I let off the loud pedal. It is why I had to install a BOV.

Like you, I have found the Turbonator makes the exhaust pretty loud and I have been contemplating a muffler. Probably an MBRP.

Thanks for all the intel, if I lift fast it definitely whoosh's and whoosh means = broken turbo.

I may open it up a hair, reduce some backpressure and wait until I get my Comp 910s installed.

You're welcome! If you're worried about breaking the turbo on sudden throttle lifts, the BOV does wonders. I used this: https://www.turbosmart.com/product/b...EFavuPkrpiG4ig

After many attempts at clamping and reclamping the boot from the IC tube to the Y-pipe, it still farts a high-pitched squeal at high boost pressures. I think I am going to have to resort to one of these.

If you were to set max boost at 50psi, do the existing boots hold without farting? Just wondering where the limit is with the current setup.

Do you need boost up to 55psi to use all the fuel from the 205/80's cleanly? I'm assuming when towing, you are not running boost up there typically, and have good EGT control.

Is boost above 40psi needed for short duration fueling during acceleration, not so much steady state? I want to understand better how you are using the truck with these awesome mods. I need to re-read this whole thread.

Probably not. Audible fart onset is about 38psi.

Yes, 55psi is to get the exhaust somewhat clean when I romp on it in the Performance tune. See below for why I romp on it.

Boost above 40psi is indeed for short duration acceleration mainly because Vegas drivers’ mission in life seems to be to c**kblock anyone merging onto the highway.

Welp, noticed a few drops of oil in the garage floor so I dived under the hood to investigate. Turns out that my y-pipe to plenum boot clamps are popping off the silicone boots as well. What was once a fart from the IC pipe to the y-pipe has kow turned into a full three-horn ska band.

these guys really are clowns. So we had exhaust brake function with the electronic actuator. Then they ditched it and did an air actuator for the exhaust brake. Now we are back to electronic actuator for the exhaust brake. The mechanical actuator has also changed multiple times.

I also like how the spool up increase is 200-300 rpm or 200-400 rpm. Just depends where you read. It’s like they just throw random numbers out there!

I can confidently say mine significantly increased spool up! So the VGT works but the marketing is so shady and awful
