I've finally gotten the engine together and in the truck, I'm to the point where I need to make some decisions on what to do for turbo or turbos for the truck. A little about the truck:
I race in 200' mud pits, truck is a full out race truck/toy. Frame is a 96 dodge Ext/LB shortened 3', body is a 46 power wagon and at this point, just the cab and doors are original. Fenders are all carbon fiber, bedsides are CF, hood is steel strap/aluminum with a CF grill. Engine is 18 3/4" back from stock location, cab is back that far as well. 6.13 gears in the diffs, lincoln locked in back and lunchbox locker in front, 47re with full manual vb and factory transfer case in high range. Tires are 38x11x16 fronts and rears are 39.5x18x15 rears
Now to the engine. 5.9 block bored out .45 with CP Carrillo hybrid pistons/rods, fully studded engine, crank girdle. Hamilton Head, ported/polished with larger valves with tube intake. Water to air intercooler with dual pumps fed from bottom out from top with 10 gallon tank. Air shutoff valve on intake. Hamilton 230/240 steel cam. Injection pump was just redone by Seth, 13mm p pump, hamilton 2.75 cam/springs. full cut delivery valves and larger holders, .120 lines. Injectors are IH 5x20 dual feeds. Fuel fed by 2 air dog pumps independantly front and side with check valves set at about 50psi if I remember right with a fuel return external regulator.
I've run a single s475, just not big enough anymore with this setup, tried running an s480 but had issues spooling it, just too much fuel at spool up, worked with Seth to fix that issue.
Exhaust Manifold is a t4 straight steed
Turbos I have sitting around right now:
s366 from ED, billet wheel, comp cover .90ar t4 foot, used many years ago when I was just starting out, needs to be rebuilt after years of 2000 degree + runs
s475 billet wheel, comp cover .90ar t4 foot .87 exhaust side
s480 reg wheel and cover, .96 exhaust side with I believe a 1.0 or 1.1 ar t6 foot
I'm at a crossroads, looking at buying a t6 comp steed manifold and running the s480 and seeing how it spools up with the changes made and getting rid of the adapter I used (t4/t6)
But also interested in possibly twinning the truck, only thing I'm worried about with twinning is I'm very limited under the hood with what I can fit under it.
What would be a workable combination with the s475 I have as the small turbo? Would a t6 foot manifold be better for twins? I've never really looked into twins before because of the classes I've been in with the different orgs, but I'm to the point of pushing out of those classes anyway with the changes I've made so might as well start looking and planning for the future.
Any insights or people I need to talk too about the twins road? Any help would be appreciated.
