what kind of hp am i looking at??
 

i have a e99 with stock turbo and stock injectors as far as i know, i have a stage 1 intake and a power hungry performance chip that adds up to 120 rwhp no cat or muff, new trans and i was wondering about how much hp im pushing now and whats the most i could push with stock turbo, ive heard u guys say 300 max with stock turbo and injectors but say 210 stock plus 120 chip is 330, so whats the deal??

My guess is you might be right around 300 rwhp... Early 99 has smaller injectors than the later year superduties.

Agreed... About 300 or so... Might make 310, but it depends on the dyno...

You can't add the HP on the valve covers to the HP setting on the chip and the intake and such...

Stock Superduty 7.3 puts out about 220hp to the rear wheels, most HP a chip will add with stock injectors is 80-100hp...

My guess is 275ish

I agree about 290hp - 300hp. Last time I saw a set up just like that dyno it was 292hp 602tq.

depends on elevation too, i did 202 stock and 260 on a 120 tune from PHP

also depends on engine condition...injectors blah blah blah. but id say your at 3 maybe 310:humm:

well thats stupid!!! so the number on the chip means nothing, but my turbo will only hold up to 300 right???

Its not really stupid if you think about how much power your drivetrain uses up to put the power to the ground. And the rating from ford or any manufacturer is rated at the crank not the tires

:nice:


OP, What's the E99 rated for at the crank? 235?

235 + 120 = 355 x .15 = 302 That's assuming a 15% drivetrain loss...

ya that is true, i did not think about that,:nice: i will have to find a dyno somewhere some time and find out for sure

ive been doing some reading and some say that chips wont work on their single shot injectors??? how common is this???

When you swap to single shot injectors, you just need to send your chip back to get reburned for them...

so its very common, okay just didnt know if that was just certain injectors or all of them,

The chip will work, it's the tunes that won't because you are tuned for split shot injectors...

okay, im also looking at water/meth injection and was wondering if i shouldnt expect a power diff with stock injectors and just expect lower egts or what i should be expecting

I dynoed 351hp in Colorado with 30% meth, and a 38r... Should pick up about 30hp... But I use it more for the cooling effect then the power gain.

Straight water is best!

so straight water is the best thing ta run, okay, im doing to lower my egts because i tow quit a bit with it, but the power gain is just a plus haha just didnt know what to expect with stock injectors. but even with stock injectors and turbo i would be expecting 30 more??

does the early 99 use split shots?

yes they do,

Yes, They are roughly 120cc AB split shot injectors.

The late 99+ use 140cc AD split shot injectors.

thanks 95powersmoker, you have helped me out a ton
