35 psi boost max

I am at the present running a tripple dog and puck stack with boost fooler that will hit a max of 35 psi on my mech gauge. I smoke real good if I dont ease into each gear and run it up slow because otherwise it is a freight train until boost gets elevated.

Before I had this I had a TST and ramifier that would hit 36 or 37 at the max. When the ramifier went south and I went back to stock I could hit 33-34 before the truck would kick back each I ran through a gear to not let it hit any higher.

I am running the super stocker 62 with the low drive pressure wheel and wanted to know what I can do to elevate my boost pressure or am I limited by my Fass 95.

I am a little green on the these dodges so I am still learning the quirks.

Thanks for any info and or advice that is given.

Not all "boost foolers" (not an accurate term) are created equally... the '05's Quad Race allows 48psi on the stock Holset.

... kind of worried what the Smarty will produce on top of that!

It sounds like the wastegate is opening a little too soon on your HTT. You may need to get a boost elbow fitting so you can keep the wastegate closed a little longer for more boost. I would be careful though so you don't over boost that thing and pop a head gasket. Did you put the resistor in the stock electric wastegate harness?

I am under the assumption it was installed when the turbo was installed. I know I ordered one but since I had some else install I am not for sure.

Where should I look to see if the boost elbow was put in and if this is my problem.

I have been figuring from posts that I have read that with this turbo I should be blowing in the neighborhood of 45 psi.

You need more fuel. You just probably are not making enough power on the upper end to spool that turbo.

I know the puck does next to nothing on the top.

When I had the ramifier even when turned all the way up and the tst 5X5 to play I still could not get it to spool any higher boost so that makes me wonder if the FASS 95 is not enough.

I can hit 39-40 psi on level 5 with boost defuel setting turned off on my Edge. I now have it set to defuel at the recommended 36 psi. I'd hate to blow a head gasket.

I see that from your sig that you still running the stock turbo and are able to hit 39 psi. I am running the super stocker and cannot get it that high.

Maybe this is what this turbo is good for?

I will have to call HTT to see what they have heard as to the normal operating range of the Super stocker 62.

The 1:1 drive pressure for that turbo should be in the 45 PSI range and that turbo will run there all day long. The boost elbow will be on the little blue hose between the housing and the wastegate actuator. It will have a little screw on the brass elbow that you can turn in and out to adjust the pressure with. It's not a standard item. Most of HTT's turbos are set manually using the wastegate actuator arm with adjusting nut. An easy way to get around that is using an elbow. While you're down there, you can look at the harness that went to the stock turbo. It should have a solid connector in the end of it. That would mean you have the resistor plugged in there.
