I'm gonna say you should see about 190 at the wheels all said and done and be turning 1/4 mile times in the high 14's. Too many guys with 2.4's are almost there and don't have the tune and injector swap for it not to be broken soon.

It all depends on the dyno. My 2.4 auto dyno'd at 142whp on a dyno dynamics dyno with similar mods (except my ss/sc injectors aren't installed yet.) Yet I turned a 15.35sec 1/4 on a bad day.
A much better measure of performance is your 1/4 mile times. Take that bad boy to the track and let's see what she'll do. Besides it's much more fun than burning up the dyno!

Um.... You do know we have 173hp from the factory right? The GMPP intake alone adds 12hp so right there your at 185hp at the crank. The GMPP catback has dynoed at around 15hp aditional now your up to 200hp at the crank. The injector swap and tune are good for a dynoed 15 hp according to the graphs on G5.net so now your at 215hp at the crank and this isn't counting a header or DP.

I do however agree with the 1/4 mile time. a good run with those mods would be well into the 14's.
god luck with the mods!

yeah in summer
soon as i meet up with wickedss2005 in columbus for the tune. and physcostevo sends me the file will be good to go. and ill be installing the exhaust wednesday. to see how it sounds and see if it throws a code b4 next saturday. i think i will easily get 175 hp to the road. will see ill dyno it after all parts are installed and then take her to the track.

i dont agree with the that intake hp gain, no intake is going to add 12 alone, unless it has ram air. now with the exhaust i think 15 hp combined would be reasonable. using the numbers to add up is nice, but its just not realistic.

Yes Lewiss has made a functional hood scoop but on a dyno with the hood shut it can not see enogh airflow to make it act like a cold air intake. All he did was give it another sorce of air rather then the factory small opening uder the GMPP's filter.
All you need to do is not seal it to the hood and let it get max air and your at 12hp. Lewiss did it, I've done it IDK whats not believeable about it. I can find you the dyno sheets from the GMPP catback too if you'd like showing the 15hp gain. Not trying to sound like a dick here but people have already done this and are seeing the gains I listed. Once I get done mine this summer I'll post a dyno sheet showing the total effect of all the mods working together.

Umm no, my stock 2.4 put down 146 WHP on a mustang dyno. So if you think that all you will net is 9-14 hp with I/H/E downpipe and tune, then there would be something wrong with that car.
Id say bettween 170-180 whp

mustang dyno
yeah the mustang dynos read low for our cars anyway so i think hes getting more than what that says. cuz they use load to read the numbers anywhos id say somewere in the 170 to 180 also should be sufficiant.

I'm gonna put this to rest this weekend. I found a shop who wants to help me with my new tune and get rid of my CEl in exchange for copying the tune for re-sale I said sure! So he will re-tune my car FREE and then he offered a killer deal to me, he said he'll give me an hour on his dyno and dyno tune it for me based off the existing tune for $75.00!! So I'll tell you exactly how much HP a 2.4 with the GMPP intake, and 20 injector swap with tune is worth and then I'll take it from there with each mod I do. $50.00 for an hour on his dyno anytime I want is a HELL of a deal!
I'll let you know asap. But I'd be willing to bet that I'm pushing 165+ at the wheels.

oy vey.. i'll go through this again....
the 2.4 comes with about 170 chp take into account the 12% or so drivetrain lose... your at 155hp to the wheels ... with a full exhaust you'll get around 15, so thats about 170 hp, about 5 hp from the intake so your at about 175 whp... then with the injector swap and a GOOD tune it's been rumored to give you between 15-30 hp... so you should be putting down 180-200, assuming your tune doesn't suck.. if your tune sucks or you're running at a higher altitude then your numbers will be much lower.. but 180 is a good number to think you're going to get.
there is an automatic that can run a 14.8 on all of the mods you've done...
supposedly psykotune's tune is awesome
either way good luck however the best gauge is at the track

He kinda dropped off the face of the Earth all of a sudden! I can't get ahold of him either anymore. No E-mail, No PM, No cell phone, No texting, He's gone.

#23
Well worst comes to worst I have a copy of his tune saved on my files so if anyone needs it PM me and I'll e-mail it to you. You need HPT to open it and you may need it tweeked a little cause right now its set for cars in Arizona which are 3000 ft above sea level and its very hot out there. Basicly the MAF tables need to be adjusted.
#25
Yes its set for AZ thats the reason I said you need the MAF tables worked with so the car doesn't think its lean at idle, my only problem!
