Sounds promising tuning limits for my injection pump is 350Hp with minimal compromise as this only 50 above the original designed. 400 cuts life span dramatically. Swap to a P7100 like Skyjing has offered7-800Hp.
So its doable with a stock motor and a cupola bolt ons.
Power to speed ??
I was hoping for 1: 1 HP:MPH dyno said ~50hp /70Tq at gov limit 2500/92.5 mph (I should have put 4th gear on a togle switch, dyno had same truble I had at Bonneville downshifting .)
1:1.85 hp:mph . The page with the correction factor said uncorrected 148hp 396tq was the best it could muster @5,950' 85°f 175hp 491tq with correction factor(lab conditions eg sea level, 25c 77f ect ect). There trying to find the corresponding graph for me.
The one they gave me and I posted shows 115hp 309tq . To the ground .
The 2nd one 1/4mi with several down shifts peaked at 95HP 1/2 way through 3rd gear fell off (this is very pronounced on steeper on ramps) made the 3-4 shift droping to ~ 40-45 hp then peeking agen followed by 3 4-3 down shifts. 1st gear is the only gear thar duse not show the defuel start at 2000rpm
The torque curve shows the tq to the ground. Including the amplification from the gear sets, the shock load torque of the 1-2 shift is about 470 lb droping from 83to 25hp as the motor slows from 2500 to 1200.
------

300hp will require more than just turning the screws.
Planning stages

Quick change rear. If i gear for peak power insted of peek gov my target will be at 2000rpm

Turbocharger

I'm looking at a Borgwarner S362SX E with. 88AR wast gated.(I like how they have both volutes wastegated individually on a single actuator) set to 30psi. (Head bolt / valve spring safe limit) sitting on top of a BD diverter valve which will turn this into a .44 air ratio below 12 PSI this should improve my drivability around town but leave the top-end open for my Bonneville aspirations this turbo will support 91lbs/min (10 hp/lb flywheel 7hp/lbto the ground) 500hp in excess of what my injection pump is capable of.

Option 2

SwitchbladeTurbothis option is a spin-off of a Variable geometry turbo . It also diverts the air at the nozzle end of the turbine housing with a shutter that moves out to expose more of the turbine wheel as boost builds. And injectors
