Dart B18c supercharged with NEW dyno graphs

[Dart]

Hi Guys
I have finally had my race car tuned

i have come to the end of my knowledge and would appreciate some help to optimize my current set to increase the power figures

My specs are
dart b18c Block
standard stroke
84 mm wiesco pistons
cr 12.3 ?? ( compression test 225 PSI each cylinder)
eagle rods and crank
full head of ferrea
exhaust valves 1 mm over size
Head B16 Jhh Ported
skunk2 spec 2 cams set to skunk2 cam specs
toda cam gears
Jackson racing supercharger 7 to 8 psi
Aqua mist water injection using middle nozzle supplied with kit ( triggered at vtec)ignition timing 26 degree to 28 advanced
toda extractors
buddy club spec 4 exhaust

My thoughts on the areas I feel my need some attention but hoping for some input to guide me<<<<<

cams need to be dialed in better for the supercharger
over or under water injection
add methanol to water injection


I am hoping some knowledge can be pass on my way

NEW DYNO RUNS








These runs are after fixing the exhaust and changing the supercharger pulley size and increasing the water meth injection

What is with the big drop in PSI at around 6400rpm?

vtec switched to high lobe of cam, it s around 1 to 2 PSI

Power seams very low, especially for a built engine. Why is the CR so high for a boosted application? Have you considered running on e85? I dont know much about Jackson racing supercharger's but cant you swap out the pully to increase boost?

Maybe get it retuned/ looked at by someone who knows what they're on about. Toda_au has made more power from a standard b18c7 SC, maybe get in contact with him.

I made 162.8 on a stock b18cr.... Only toda cam gears, toda headers, toda flywheel. And some horrendous press bent cat back

And genuine Honda air filter/intake on 7psi

Higher CR usually yields more power but also more lag with a turbo, so maybe it's irrelevant with a SC because the belt isnt driven by the exhaust?

But I was kinda expecting 180+ kw from the build specs, dyno variances aside. How big is the BC spec 4 exhaust? 60mm?

[Dart]

Exhaust seems to be fine size wise. No cat.. I drive car to track so e85 not an option yet. Those 180 + power figures would be nice.

[Dart]

All ready running the bigger crank pully So no more boost
I'm scratching my head to know where to find 20 kw

You could always carry some jerry cans with you to the track, i dailyed with E85 for ages with no issues with finding fuel.

IMO your cams are too big for a supercharged setup, standard cams should make more power, if your tuner can set them.

Not uncommon with the crap intake manifold setup these kits have,you are saying EAGLE Crank and rods is this a stroker setup? and what Skunk2 cams tuner 2 or Pro2

[GSi_PSi]

damn, that this is built aswell, i wonder how much power if it was a turbo setup
