Well this weekend I headed over to the local Dyno, and straped the 2.4 down to get some base line number's. This was on a Mustang Dyno that's why the numbers look a lillte low. I put down 145.7 HP @ 6000 & 146 TQ @ 4750


Not to bad for a stock 2.4 IMHO

 

They sound ok for a Musatng dyno--not sure. I did 158hp/154 tq with an SRI--old car.

What transmision do you have?

 

Those numbers look like a 2.2L not a 2.4L.

 

?? a 2.2 doens't even make that much at the flywheel, let along the wheels on a mustang dyno

 

Remember this is on a mustang dyno, they always say lower number’s because they put a load on the engine to get more realistic numbers. But if you add in a 10% differences between the mustang dyno and a Dynojet my number’s are 160.27 HP & 160.60 TQ

 

+1 - thank you NR... My 2.2 dyno'd 122.4whp with 2.5" cat-back, CAI, and 62mm throttle body. They're rated 140hp factory, which is 119whp w/ a 15% dt loss. chances are that the 2.5" exhaust hurt me being n/a, but it was a couple weeks before the procharger so oh well
serious? that's crazy mang... 2.4's flywheel rating is 170hp... 15% dt loss puts you right at the 144.5whp mark that you pretty much measured. unless the 2.4's are as underrated as the redline, i have a feeling you wouldn't see too much difference on a dynojet. I know that mustang dynos are historically "lower" than the dynojets, but the numbers you're seeing there seem to be right on - with the math anyway

 

The tuner that Dynoed my car said that his dyno and the dynojet down the street had a 18% differnce, and if thats the case I would have 170 something. That's alittle high for a stock 2.4 so I only did a 10% difference.

 

Mustangs do rate it a little more conservatively... but not 10%!!! Your numbers sound realistic as is, maybe +/-5 hp

 

I would think that 150ish whp is ok for a 2.4L so you seem right on track regardless of the dyno

now get some mods!

 

Those numbers sound about right 145-148 hp is about the norm stock. I had my car re dyno'd friday because I'm tuning and I'm having trouble, not much with the afr on a dyno jet and reading the afr. I'm at like 13.1 to 13.4 so I went to another place that had real time afr which was 11.9- 12.8 I don't know what one to trust anybody have input.

 

Mustang Dyno's calculate WHP.

Dynojet (Egojet) calculate BHP.

 

The numbers in my sig are baseline numbers. These were done on a dynojet.

 

Why is your TQ so low? Are you a manuel or auto?

 

im thinking that is auotmatic. A guy in our team in VA did 160 with just a short ram mod

 

Yea its an auto. I think we dynoed it in "I" if I remember correctly.
