What kind of WHP numbers should an '06 2.4 put down bone stock. I'm guessing it will make 150-160 based on accelleration.

Thanks!

 

155 whp if 5 speed.

 

It's an auto. So what are we looking at 145-150? It seems higher, but I guess it is pretty light.

 

Less than 150 for sure. In fact because of the poor gearing in the auto, a 2.2 5-speed is probably quicker.

 

no way!!!! i have a auto 2.4 and i pushed 152 whp

and that was when i was stock

 

Oh, you're a stunning 2 whp over 150. Go back the next day and you'd be under. The day after on a different dyno you'd be 160. Fact is... the auto sucks power.

 

auto tuned=different

but yeah stock 2.4 auto will be between 145-155whp...mine put down 154whp stock
5spd ive seen between 150-160 stock

 

the auto isnt that bad on this car and when you tune the auto it really wakes up. i dont see a 2.2 5 speed beating a 2.4 auto if both are raced properly.

 

2.4L auto tranny 3.91:1 final drive is an excellent ratio for accelerating. You also forget that the converter is actually a plus under acceleration -- multiplies torque under acceleration because of the stator. There's more to an auto than is widely known...

 

i agree with red

 

agreed..this is why a tune opens up the auto 2.4 real well...a tune done right..lol

 

Yep, the torque converter really does give a big boost in the low end torque delivered to the wheels....question is, can you get it hooked up? If you can, it's soooo much easier to drag an auto with consistant results...too many variables with a stick.

Sure hope hptuners gets the 08 2.4 unlocked for us soon, would like to do a few things that only a tune can do

 

hey i do need to tune my car looking for a tuner

 

HPT is unlocking the 08 2.4L this Spring from what I've heard.

 

how much do people usually charge for a tune? and where's a good place in the houston area to go?

 

the guy installing my s/c has the beta software that nobody else has to tune my 08 sport

 

I normally charge between $200-250 depending if it is an Auto or five speed, and mods
done to the car.

 

check my sig for my numbers. But a tune would really help with an auto.

 

depends on the conditions. Some shops are warmer or cooler then others and eeryone knows that cooler weather is better to run in. My car runs at little shittier when its above 75 and humid. But when its about 50 outside its perfect. Im sure there are more variables then that though. As for the shifting in a auto 2.4. Can you get a shifting chip for the 2.4 like the 2.2 has? i have a 5speed but i was just wondering.

 

If you mean the B&M shift-plus...works on both the 2.2 and 2.4 autotrannies. The auto is pretty much the same -- just the final drive ratios are different...3.63:1 in the 2.2 and 3.91:1 in the 2.4

 

the shift kits are good for the 2.2 cuz not many companies have tuning available..but the tune on the 2.4 opens the whole care up..def get a lot of gains on a good tune.

 

Got her on the dyno today, and you guys were right on. Bone stock and running 87 octane, it put down a couple 146whp pulls and a 148whp pull. With a quick PCM mod to run closer to 13:1 AFR, and 1 degree added timing, it put down 150. The real improvement was in the average HP gain of 6whp and nearly 8 ft lbs of torque gained at 4800 RPM. With another degree of timing added it already had KR. and hit 150whp again. I'm thinking some exhaust mods would allow a more aggressive tune. Otherwise, It's going to need 89 octane or higher to get much more out of it without any mods.

We will keep you updated with our progress.

 

Run 91 or better...you can turn the timing up a little.

 

Thanks for giving the dyno results. I got a g5 gt and its a auto. I only have a k/n typhoon intake for mods so with that i should be atleast 160 whp.

 

my stock number are in my sig. as of now last time i had it dynoed it was 170whp and 168wtrq
