Dyno

[robmustang201528]

Putting my car on the dyno again . ARH LT x pipe stock mufflers, cold air tune. Made 430 hp 390tq in 100 degree weather. Hoping for 440 and 400 tq. Temp should be 60 degrees tomorrow. Do you think I'll make more hp with the lower temps? Or should I wait until its colder out? I know of in 30 degree weather it'lol make more power but that's not realistic. How much hp do you think I'll gain on the dyno in 60 degree weather vs 100 degree? Thanks

Should, NA loves cool air.

I'm hoping for 450-460 after I get the CJ on.

Are you just trying to get a low number on paper?

If it was sae, it likely will make the same. It'd corrected for temp/humidity. Obviously it can't account for things like pulling timing but I wouldn't expect much more.

What intake? Im also curious on who the tuner is

 

[robmustang201528]

JLT cold air. Pro dyno tune

Interesting. Peep this guy. Hell of a difference. Same place you were just at.

Only difference is he has the off road x pipe and the mufflers. I still have the stock mufflers and high flow cats. That's the only car I've seen, make that much power NA. I've seen 425 to 445 with my mods NA

You didnt mention catted in your OP. Mufflers only add a few hp. By those cats take a decent 10+hp from my understanding. Also that heat did you no favor. Da had to be really high. Ive seen a couple handfuls putting out 450-470s. Heres another for you.

Alot of the high hp cars are making high numbers in the winter. Nov Jan and feb. I haven't seen anyone make over 445 in the summer

I made 446whp 436wtq corrected on a 95 degree day in Florida .

 

[robmustang201528]

Idk then lol. Either I got a lemon or my is just hiding horsepower somewhere.I hoping to make what u make on a cold day

stick cars seem to do a lot better on a dyno than auto cars but dont do as well at the track.

 

[robmustang201528]

Exactly l. Yeah I have the performance pack 6speed

Hotter months typically show lower actual readings, but have higher correction numbers. Colder months show higher actual readings and lower corrected numbers. Just depends on if your using SAE or STD factors. Local to me in high elevation summer months, the dyno's in our area will show sometimes 22-24% correction.
