My OBS "build"

So it's getting close to being done, so I figured I'd share what I have so far.

I'm not doing this myself as I have no time, but a great shop is doing the work for me.

The list:

Adrenaline HPOP
205/100 hybrids
T4 mounted S366, billet wheel
The shop built their own fuel system, fuel labs components
Of course new tuning via TS chip
Replaced the Swamps IDM under warranty, it stopped working properly after about 3 months
New UVCHs


Fixed the leaking front and rear mains

Should be done soon, here are some pics.

in your pic it does not appear that the regulator is on the return side. that is an issue. otherwise well done

I have no idea if it matters which way the fuel flows through the head. I'll bring that up to them though.

AFAIK it doesn't matter. Dude I met here who did a WVO has his dino-diesel running one direction (IIRC, back-to-front) and the WVO running the other.

Just an opinion, I would think that it does indeed matter where this motor is concerned. Since this motor is being build to make real power and not for the case of towing reliability or high MPGs please consider that the motor fires hole 6 right before hole 8. Under hard acceleration the fuel would be pulled by number 6 to leave 8 "dry". There are two reasons for having the heads flow back to front in these motors, air bubbles move uphill and 6 starves 8.

Just an opinion...great work in there OP!

I assumed that the flow could be reversed since it is a "common" fuel rail.

Big fuel, that is a good point.

All good things to think about. As to what point it would be starved, how could the starvation be measured?

More pictures. The truck is done. Made 359 and 590, but should be more b/c the tranny was acting up and we didn't want to break anything.

It is amazing how fast it is now. A little smokey but tuning can be tweaked.
