my school is doing a dyno day may 16 they are charging 20 bucks for 3 pulls and all money goes to a little girl that has to have kemo. i was thinking of dynoing my truck any body got any ideas on what it will pull? its a 4.6 with k&n cold air intake and dual 2 inch pipes with 20" rims if that helps any.

also if any one wants to come it is at wyotech in blairsville pa may 16 9am to 5pm first come first serve.

 

the 5.4 guys seem to lose about 80 HP through the drivetrain

you have 260 crank HP...but those 20" rims are gonna kill ya as well. I'd venture to say you have about 160-170 RWHP


could be higher though. Your tranny is different from the 5.4 tranny

 

im hoping to be atleast 200 prolyl wont get it but i can hope. lol

 

doubt it...but you never know. The tranny in these trucks eats up the HP. Since yours is different, it might not be such a HP hog.

and to be honest, I haven't seen any 4.6 dyno runs from a Truck.

 

wow, i wish we had something like this when i was in school

 

what is the worst that can happen on the dyno?

 

nothing im sure it no worst than a high school driving running it just kidding just check all your fulid levels have fun you will under 200 20 bucks for 3 pulls is cheap. let us know what it pulls

 

What year is your truck? That will determine you fly wheel HP. 04-06 is 231 and 07-08 is 248. If you can find some 17 inch wheels, definitely use them.

 

I'm gonna guess 172hp.

i saw a dyno chart from K&N when i was looking for intake, i think it said 191hp before their intake.

edit: found it

both of there charts for the 5.4 show about 190-195 hp stock??

Dyno at your school?
Dang.
I also did not realize that there was so much power lost in the drive train.

 

Going by those charts, the 5.4 is only 3 HP's more at the wheels?! I bet the 4.6 was 2WD, short bed, reg cab, and 3.73 gears.

 

I'll say 175ish to the wheels.

And a dyno day at school for a good cause is pretty damn cool.

 

Screw selling cookies for fund raisers, bring on the dynos.

 

well i go to wyotech thats why we have a dyno here in the hppt(high performance powertrain) building.

i have a 04 4.6
