Stock 5.3, GT45 Turbo, BTR Stage 2 Turbo Cam: New Personal Best but we fight the boost controller

Turbosmart boost controller gives us issues but we finally make a decent pass.

[@BadLuckGarage]

Heck yea man. Going faster and faster ever trip. That’s what you wanna see. 🤘

[@waynesspeedshop8167]

love your build! I have a similar setup in my s10

[@user-iz4xj1yk4s]

Nice runs man

[@CarportGarageDragRacing]

Thanks

[@genzllabk23.8fastestinnwi8]

Would you recommend the btr stage 2 turbo cam over the the btr stage 3 turbo cam ?

[@CarportGarageDragRacing]

I am not sure. I have only tried the BTR 2. I would think the BTR 3 would require a better intake than what I have.

Hey man little imput your timing is way to low i have a twin gt35 setup on 12 psi and the tiing is set st 29°initial and then pulls 3 degrees 26°becayse you give the motor 6 psi befor any timing is pulled at all yes it is on e85 and yes i daily drive my squarebody do that and its going to be a whole diffrent animal!!

[@CarportGarageDragRacing]

Ya I'm on the low side. I'm just trying to kinda sneak up on it.

[@CarportGarageDragRacing]

After more testing, at the track it actually like 18 degrees at 16-18 lbs boost

[@richardkamowski4656]

What injections and pump are u running? I have 850cc injector and a hellcat 525 pump I’m trying to use with a 4.8 gt45 and e85 hoping to make 15-20 pounds max

[@CarportGarageDragRacing]

I have the exact same and run E85. I doubt you'll see anything higher than 14 lbs with a GT45 though.

[@BoostedBlazer]

@@CarportGarageDragRacing I have a GT 45 on my 4.8 and I have it gating off at 15-16 PSI but it'll do 20 easy on my setup.

[@CarportGarageDragRacing]

@@BoostedBlazer what kind of fuel system do you have?

[@BoostedBlazer]

@@CarportGarageDragRacing Stock LS Non return style fuel rails, Evil energy return style regulator with 6an lines, Siemens 80 lb injectors and a Aeromotive 340 pump.

[@CarportGarageDragRacing]

@@BoostedBlazer I am assuming you are on gasoline?

[@ChristianHernandez-vm2fk]

What valve springs sir ?? Looking to do the same setup on my fox

[@CarportGarageDragRacing]

I ordered everything together from BTR they recommended for that cam, springs, pushrods, valve seals, etc....

[@JesseSeg84]

Stock 10 bolt rear end?

[@CarportGarageDragRacing]

No, it has an 8.8

[@fourleafcloveer5011]

The boost controller is suppose to be teed between the wastegate and the compressor housing. That's "On gate" with a tiny bit of restriction. If you blow into a boost gauge, it won't show even a pound because your mouth isn't strong enough to blow a pound no matter how much you suck. lol

[@CarportGarageDragRacing]

I had the compressor housing of the turbo going to the boost controller, then it went into a T and went to each wastegate, I have 2. It still did not work correctly.

[@CarportGarageDragRacing]

Actually the average person can blow 1-2 psi, but I was only blowing through it to make sure there was no restrictions.
