Hey guys what do you think i should have projected hp gain with installing Header, highflow catted dp, Gm sport exhaust, gm intake, and 2.0 stock injectors. im saying upwards of around 185 to the road you think thats plausbale. let me know and theres a poll for it too woohoo.

ryan.

ps im saying around 185. oh this is also with a tune from hptuners...

its the 2.4 guys

 

What do you have a 2.2 or a 2.4?

 

It's in the 2.4l performance forum!!

 

i hit 177 and i have gmpp i/h/e 2.0 injectors tuned

so you'd be lucky hitting near 190 with the dp, thats if you can squueze another 13hp out of it

 

yeah im thinking its puttin down around 150 or alittle more right now to the road with just my intake on. um yes i have ca header, ca dp, and gm exhaust, 2.0 injectors. tune will be on the 28th in columbus.... so hopefully we can sqeeze out some hp somewere. after everything is on im saving money for bills i have stacked up lol!. then later this summer twm shifter and rims and then projectors. ill have to get some photos guys when i go to columbus thanks.

With a good tune you might squeze out 185-190 at the crank not at the wheels.

 

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'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!

 

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.

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!

 

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.

ryan.

 

to the wheels your looking at about 155-160 w/ a decent tune

 

You don't agree with it? Um...ok heres a link to a dyno sheet that prooves it...
https://www.cobaltss.net/forums/2-4l-le5-performance-tech-46/gmpp-intake-dyno-numbers-47695/

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

 

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

 

you mean physcostevo i cant get ahold of him im trying to see if he can send me his tune b4 the 28th which is the big columbus meet. and thats where im getting mine tuned and injetors installed so i dont know.

ryan.

 

lol physchostevo psykotune... you get the idea I wonder if his tune works on ions cuz I would love to drop about 1second off my quarter mile

 

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.

 

i hope he can send me that tune file b4 next weekend though d***.

ryan.

 

DAMN i hope he comes back... oh well I"m sure I can find someone else to do a pretty good tune... it might not shave 1 second off your 1/4 mi but it also might not throw a few codes and disable your cruise control or whatever hehe

 

better not. stevo said hes the only one with a good tune for injector swap and full ex hmm well wickedss2005 is gonna tune my car but will he do it good idont know will see. in columbus.... 28th meet.

ryan.

 

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.

 

hmm i'll talk to one of my friends about it who tunes Redlines and see what he thinks .. .

not only is it set for arizona but it's also set for an automatic isn't it?

i'm in NY ( 60 miles north from NYC) which is closer to sea level to say the least.

 

You can leave out the transmission part OR just copy and paste the engine tune into your tables rather then mess with anything else.

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!
