That's a cool story bro, and I'm not arguing that their data is precise and detailed, but every single tuner in the subaru community has proven (with testing) that these "1000cc" injectors flow 100-150cc less then EVER OTHER 1000cc injector they ever tuned with.

I'm currently running them on my forester. Scaled to 850 or something like that. If you're familiar with opensource tuning software I can send you my map. IPW is calculated differently than ms or aem obviously, but its very accurate. I plug in 1000cc and the car is lean as crap with tons of fuel correction. I plug in 850 it runs fine. I throw in DW1000's and plug in 1000cc car runs fine.

You can throw numbers around all you want, but unless EVERY SINGLE other 1000cc injector flows more than 1000cc by a good 100-150cc, then your opinion on the matter means sh*t to me, no offense.

You're making yourself look like a total retard, Vlad. Do yourself a favor and take 30 seconds and look at the flow numbers ID posts on their website for the injectors. They flow ~880cc at 12v and ~910cc at 14v. That doesn't change the fact that they will still flow enough to make 700bhp on gasoline, since I actually looked at the data and procured the flow number based on duty cycle and rail pressure before doing the math.

But hey, glad to hear the hivemind Subaru collective has done the testing to agree with the numbers ID published years ago

You can call me names and be condescending all you want, doesn't bother me.
I wont argue with you more, since we're arguing about different things.
I'll just sit back and watch Min attempt to make 700hp on these injectors. If he does, on a non-inflated dyno, I'll shut up and eat my words.

sigh

This weekend I hope to figure out my stupid intermittent power/ground/short issue. Will then pour the meth in the tank and have at it and see how much boost I can run at 100% IDC.

Let's see what the weather forecast is for this weekend....

Rainy!

What a surprise. sigh


Oh and BTW my car voltage drops to around 12.5 at redline. Does not bode well for MAXPOWER.



Also per JayL's advice I'm gonna check my dead times again.

High impedence (witch I think is what the miata takes I don't recall) 1600cc bosch injectors .

288.99 to your door. At that price it would be worth having sit on a shelf just in case. I know it on ebay but screw it the power you are trying to get you should just run -4an line to each cylinder and let it fall in it will burn.lol But seriously they can be had for a decent price.

Ill bring my optima by your house to try I wonder if a bigger battery will solve your problem. Miata batteries are really small. You can try a real mans 800cca battery instead of the miata 400cca.lol

If you like idle quality, low-speed driveability, and motor health, there are some things that are just worth paying for.

Idle. My idle is 1200 RPM and I'd be ok with a 2000RPM idle. Why? Because racec...

Plus it would make clutch slip into 1st easier.

Gonna try Sean's Optima.

If no worky I like the idea of second battery in parallel. Not sure if that is joke or not but it sounds good. Fuc I will load my trunk up with Prius if it gives me more fuel. That would be awesomely wrong.

I don't understand why you think that a battery issue is causing the high duty cycle. It's a Bosch 044, you aren't running out of pump.

Its a joke, or should be. Run a real battery if you think that's the issue (but its not). Batteries sit at 11.8 when not charging, so it'll drop down to that when the alternator isn't charging. Why haven't you put an FD alternator in yet?

A 26R72 battery has a lot more CA and CCA while only being a bit bigger. With minor mods to the holder, it fits like a glove.

Given that i put down a whopping 280hp last time (on drag radials) i would be surprised as well. Only one way to find out.

If i can put down 600 on that dyno i would declare "mission accomplished".


Chpwqbwbbbsnqnm where is how to instructions for fd alternator?

...yeah, really. I think it's probably pretty relevant, seeing as how the OP has his fuel pressure set at 70psi base with a vac-referenced FPR to compensate for boost.

Do you think the 0.55 BSFC is off? Remember this is US units, not metric units - I'm using lbs/hp-hr.
