ok i read the sticky about mafs but still have a couple questions

1. to calculate injector size... do you use flywheel or wheel hp?
2. do bigger injectors = worse gas mileage for dd?
3. i already have a 73mm maf, and in the future i want to run 30lb injectors how do i get my computer or maf tuned for that?

Flywheel horsepower the engine doesn't care what going to the wheels

2. do bigger injectors = worse gas mileage for dd?

the gas mileage may possibly decrease .....

but most likely not enough to be concern with

3. i already have a 73mm maf, and in the future i want to run 30lb injectors how do i get my computer or maf tuned for that?

nothing needs to be done to the computer.....

the MAF needs to calibrated for the new injectors....

Curious what is you reason for going to 30lb injectors.....

see chart below

yep i looked at that chart..

and like my sig says...im starting to prep my stang for nitrous...and i wanna run a 200 shot on stock internals...

but dont think im crazy just yet...

my plan

30lb injectors
255 fuel pump
fuel pressure reg w/ gauge
msd nitrous timing retard 8 degrees when using the bottle
93 octane
colder spark plugs
msd rev switch - nitrous on from 3300rpms to 5700rpms


...but maybe i still am crazy... lol

o and how would i go about re-calibrating my maf for new injectors? sorry if this has already been covered.

I don't see any reason for you to need 30lbs. injectors right now.
Just going to larger injectors doesn't make your car faster. Remember that injectors do not MAKE power they SUPPORT power. Kinda like changing to a big lopy cam and keeping the crappy E7 heads (which BTW is a big pet peeve of mine) .

You either have to get your computer tuned for the size injectors that you are using, or buy a new MAF sensor that is already calibrated for the size injectors...

i understand injectors dont make power they support it, but i posted that i was shooting for a 200 shot... and the injectors will not be installed until i am running the nitrous.

o wow, that sucks looks like ill just buy a new one thats already pre-calibrated for whatever size injectors i decide on.

Why such a big pill of NO2???
With the GT40 setup you have, you're already close to 300HP, add a 200 pill and you're pushing over 400HP out of a stock block.

Eh, I still think you should spend that money on a strong short block first. Risk is exillerating sometimes, but blowing your engine up and not having the money to fix it is exillerating in a totally different way.

But hey, it's your car right?

200 shot on a stock block........

you can do it.........
















ONCE.........
