I'm finally finishing the setup in my truck. Putting the 2 Walbros in today and will begin boost tuning. Here's the setup.

Stock 150k mile 4.8L
KBRacing hot side
BW S372 83mm turbine
Head studs
LS9 gaskets
Patriot dual springs
Hardened pushrods
LS6 cam
100lb injectors (so like 120 @ 4 bar base?)
Twin Walbros
E85
4L80e
Circle D stall

I think that's about all. I'm going to push it to whatever it will have fueling for.

Anyone with experience on similar combos, what should I rev this out to? I'm going to street tune it first before going to the dyno.

I'm thinking somewhere around 20lbs and 10s in the 1/4 would be fun. And 4wd will be nasty on the street

 

What pumps 255's? This will be a nasty street setup.

 

That turbo will push a 4.8 truck into the 10s pretty easy.

 

@10 psi......

 

I'm interested to see what you can get out of this set up. When is the first track date?

 

HAHA yes. And I love how that smiley is named cody lolol.

 

Twin Walbro 255s. Bucket is modded and ready to go back in in the morning. Hoping for the track next weekend.

 

Might have to run the fuel pressure at 3bar to get those pumps to push enough fuel.

 

All together, did some initial tuning. At 15lbs so far and still pulling fuel out of it. It's getting fun Launches well too.

 

You will have to upload some vids ASAP
