I just came back from the dyno. I did 3 pulls, I got 320WHP and 347wtq on a mustang dyno. I want to know if this is a good number for an 03 with bolt ons, 10.5 hotside, 272 cams and gears, 255 fuel pump, and alcohol injection?

-HKS 272 cams
-AEM cam gears
-walbro 255 fuel pump
-10.5 hotside
-Alcohol injection
-Dynoflash Custom Tune

 

What does 'bolt ons' mean? Have a detailed mod list?

 

You should get better numbers with Alky but mustang dyno gives you lower number...

 

Nice Numbers

 

Nice numbers...I had similar numbers and mods from back in 05' with Al's custom tune.

320whp/335tq @ 24psi (no spiking) on a mustang dyno

-stock intake w/drop-in filter
-3" Downpipe
-3" Works cat
-3" hks cat back
-MBC
-HKS 264 cams
-walbro 255 fuel pump
-16G w/10.5 hotside
-Alcohol injection (meth)
-Dynoflash Custom Tune

 

only runing 24 lbs on alkie wow.........that not to good look at my mods and i just dynoed on dynojet 352\338

 

Well I would think that is pretty good for a Mustang dyno. Although I would run 26-28psi on alky. My friend made 376/393 on a Dynojet with 272/280 cams and basically the same bolt-ons as you at 28psi.

 

I think thats right were it should be! I also had a tune from Al today and got 291hp/291tq. This was an 03 also without the 10.5 hotside, crower stage 2 cams, and no alky. Im very happy with the numbers. More then that the car feels great. and thats really all that matters.

 

Well, we can play dyno numbers game all day on the internet.

But on the track my measily 320whp @ 24psi equates for avg 112 mph trap speeds on my previous simple mods.

 

It really depends on the calibration on the dyno

On Buschur's dyno those numbers would be very impressive as it reads 20% lower than a dyno jet

AL

 

Al, do you think if you lean out just a little bit up top it can make more power?
