Dyno Tune 1/27/2022

Pump gas tune, 560 whp / 624 tq - pulley change only and cooling mods, up 15 whp and a lot in torque!

Meth tune, next week

Bugs being sorted out then return next week. Pump too small- ran a little lean up high. Got the 75L pump, initially thinking single nozzle pre boost, but need the 190L for the 4 nozzle post boost. Sensor wiring making controller blink and led not working.

Dyno showed great torque gains and you could definitely see where the cam stops at around 5800.

No pics of chart till I get the meth sorted.

Stage 3 coming soon!

Lingenfelter 10.1:1 CNC LSA Heads. Flow I 358 at .650”, E 234 CFM at .650” (or equivalent)
Cam, TBD. Been looking at Steve Morris Racing Stage 2 Asymmetric lobe
Cam supporting mods by Steve Morris Racing
Dyno TBD

Stage 3.5
Synergy or Kong blower porting
Katec or NW 103 TB

Curious what gains are for porting at this level, that is why it is scheduled last. Will be looking at percentage of gain which should scale across the board.

Went to Test n Tune today at Pacific Raceways in Kent, Washington. 1st pass was 11.90 @ 122, second pass 11.03 @ 133 (that’s when they told me I needed a fire suit so I got one at the Pro shop), last pass was 10 96 @ 134 spinning down almost the whole track. Then drove hone with a McLaren and Lambo. Great day all in all!
