Dean 250 for you I think is pretty reasonable. I hit 250 with just OR H pipe flowmaster cat back, and K&N cold air intake. But every car is different.

Yea I'm really curious to see the difference when I put the Diablo tune on it.

S197GT07

Now do you know if protree uses a dynojet or a mustang dyno? Big difference!

All i have is a custom tune, and i've seen dynos of tuned s197's anywhere from 265-300rwhp. so im hoping for a solid 275ish, but we'll see.

What is the difference between a mustang dyno and dynojet? Always wondered that and when I would think to look it up I would get sidetracked.

S197GT07

pretty much its the way they measure the power. All you need to know is a Mustang dyno always reads lower then a dynojet.

smitty2919

Which is more accepted/more accurate? I know the real numbers are track times. Even though there are more variables at the track (traction, driver error etc.)


I'm googling 04 GT's with nothing more than exhaust/tb+plenum and a tune for mods....they range from 240-252....we will see.

The website says Dyno-jet.

S197GT07

I think that the more accurate is actually a mustang dyno. I know there are far more cases of people who use a dynojet and dont get the trap speeds they should.

smitty2919

Well then we will see how much difference a 75mm TB/Plenum O/R X and magnapacks make really make lol

S197GT07

Yea it will be interesting. I know for the 3v's a TB does nothing unless you're boosted/have like 400hp N/A. And any exhaust mod gives no power except for longtubes.

Also, for me, in stock form 300hp ~ 255 to the wheels. I'm excited for getting the graphs
