steped up to an HX35W/12 holset turbo
THIS IS THE STRAW THAT BROKE THE #1 RULE CAMELS BACK
... #1 RULE IN ADDING BOOST TO DIESEL . "YOU MUST ADD FUEL TO INCREASE BOOST THAT IS HOW IT WORKS." EVERY DIESEL SHOP AND PROFESSOR I've SPOKE TO READ ABOUT SENSE 2014. With the exception of Mr Blaylock the creator of the Switchblade. he gets lower lag but not higher max
Same fuel tune from when I got the truck.

H1C/21cm^2 12PSI (naked) 1psi 600 EGT 250-300'
H1C/16 17PSI (full wrap) 1psi 500 150-200'
HX35/12 21PSI (naked) 1psi 375-400 <5'
lag 1 to maxpsi at highway speed
stock 21cm 15sec (1 thousand 1, 1thousand 2....)
H1C/16 6sec
HX35W/12 1sec

65 cruse flat land no wind egt/boost
H1C/21 600/0-1
H1C/16 500/1-2
hx35w/12 500-475/3-4

max reachable EGT
H1C/21 1075
H1CX/16 1000
HX35W/12 900

boost to temp coralation
.......................500..600..700. 800. 900. 1000. 1100
H1C/21............. x ...1 ... 3 .... 5 ... 8 ... 10 . . 12...
H1C/16................1 ..3 .... 5.... 10.....15....17.... x
hx35W/12..........3.....5.....10.....15.....20.....x.... .x

tune the turbo to tune instead of tuning to the turbo.

deciding on the Switchblade .95AR or Diverter Valve T4 .88AR divided with a Borg Warner S361SX-E to S362SX-E. (S360SX is out it is missing the new tech I'm after). both increase velocity /*power in the flow TQ applied to the turbine and progressively open to allow acquitted flow to support more than Aeroheads proposed 300hp target.

-------

300HP @????RPM=TQ @2000RPM
