ja those will work perfect they just require a different plug

Balls! i suspected as much, i think i do have spare plugs for them

stock injectors cannot do 170wkW.

Sorry boet, but on the stock 370cc injectors you have just over 150kW on the flywheel at a duty cycle of 90%.
With 444cc injectors you can get to around 190kW on the flywheel.

Depends on the dyno.

Yes of course.....silly me

I disagree with those figures there are multiple variables that come into play when it comes to power no one can truely say a certain injector is good for certain power depends on what fuel what fuel pressure you are running there to many other varialbes at play to make such a bold statement. if i run 93 through my 440cc and get X amount of power and i run octane booster or water meth or av gas though the same injectors but are able to advance the timing i will get more power at the same duty cycle. but one thing is for sure the stock injectors are not good for power lol

if you really want to see power to injector size all the leading injector guys have calculators on their website

well i know from one dyno to another you wont get exactly the same reading but i always thought Dastek is quite reliable. as i mentioned fuel pressure regulator has been fitted, rx7 series 6 fuel pump and NF Black octane booster was used when the dyno was done. anyway, the bhp injector cc formula i saw on the net had it cc/min over 5 (dono what factor the 5 is but ja) times number of cylinders = max BHP (fly @ 100% duty cycle)

370 / 5 x 4 = 296 BHP (fly)
296 x 0.9 = 266.4 BHP @ 90% duty cycle which is 199kW fly.

so 171wkw isnt impossible, at least thats what Dastek says.
