Debunking The Myth of the GTX3071R ATP Stock Location

[pikadosboy]

Being a professional shop here on So Cal EVO and in for the long haul, I tend to stay out of the shop warz part of things. I gotta sit on my hands with this one. I'll honestly answer any questions on anything in person however. With this thread (and life in general) you will find truth in the middle somewhere.

Cuz I never seen a garret turbo produce more tq than hp.

You need to get out more J

do u haveÂ* proof with a graph, I can't believe a evo with a 35 r making over 100 tq compare tp the hp on a 35r.

'cause I just make up random shit

I present three Garrett Turboed EVOs with more torque than HP:

In terms of the Church Dynapack dyno, I won't go naming any names (although pretty obvious) but I was told by a trusted tuner shop that the Dynapack could not be "adjusted" like you could with the Mustang or Dynojet. All things being equal, that implies that a dyno pull on the Church dyno should be virtually identical to a pull on the "trusted" tuner's dyno. This certainly makes my curiosity nerve tingle...

Amazing how asking a couple of direct offline questions will clear up a lot of confusion about how a non-adjustable Dynapack can be "adjusted." Simple answer, a different model version.

Might say it the wrong way, I was talking about garret 30 trims and up, is almost impossible that a 35r will make more tq than hp by 100, and if there is I was wrong @ my statement.

It is all what you do with the available boost. Run with no wastegate and you will always have more torque than HP. By quite a bit. Usually people tune for a given boost pressure because of a drivetrain limitation and then at some point you run up against the turbo's air pumping limits where boost starts to taper and the torque falls. The turbo's airflow is what ultimately sets the HP at the top end. But with unrestricted boost at the bottom end, you will get crazy loopy pikadosboy cornfusing torque. Sure it isnt normal or common, but it is out there for various reasons. Now you seen it :-)

i love mike.

Only the first graph shows 100 tq over hp. And that thing is hitting peak torque at under 3k rpm... Wow, what turbo is that?

[HMatt]

^No shit right?

[EvolutionXtacy]

my guess.... a GTX3076R?

The first and last one are secret sauce. I could tell you but you would have to turn in your keyboard. They have to live with airflow limits. The middle one is our shop car set up for a class with a power to weight limit.

Mike, I want my TQ/HP curves to make circles too!

Can you make it look like this?

[amaev05]

That kind of power requires a supercharger and twin turbo kit! ^-^
