It痴 on my list to do. But the problem that i知 running into is that the shops that actually have a dyno only use it for tuning and hours long sessions.

But i知 really curious to see what kind of power this 2.5l is putting down with all of these modifications that i致e done.

I do want to put in a higher duration cam, but if I do that i知 not sure if I can keep the 1.7 duration roller rockers.

But for now, I知 done with modifying this 4 banger, and I知 working on fixing up the suspension and getting some other quirks worked out

 

STOP IT!
Your speedometer only goes up to 85mph, and there is no way you took it up there with a stock 2.5L
I just got back from a 2000 mile trip to Colorado, and my "built" 2.9L would not do that! I was lucky to get it up to 75mph on the down grades. OH! And trust me my engine is running PERFECT!

And 22 miles per gallon?
Seriously?
Stop it!
Just stop it!


The 2.5L engine is a turd.
And you know what they say............... You can polish a turd, but it is still a turd!

 

Maybe his Jeep has the tires off of a Radio Flyer

 

 

90+ in a 2.5l

What size tires and weight are you running? I have a 2.5 without any real modifications done to it yet and I've read that keeping the weight down and tires smaller drastically help with the output of a 2.5l, that said it is a turd but I am able to see mine max out the speedo on the highway even on inclines.

 

I don稚 remember because I just put bigger tires on mine. I think they池e equivalent to 29 inch tires, but I can check in the morning if I remember.

And yes, smaller tires will help, but the 4.10 gears in the rear (if you have the 5 speed) helps a lot.

 

Where are you located? My brother has an AWD Mustang Dyno on his property in Morgantown , WV

 

I often wonder why folks don't put their location under their avatar.
