The fuel curve is the way it is on purpose I have played with the fueling and running it very very rich in the midrange does not change power one iota and keeps it extra safe so that when the boost slams, there is plenty of fuel waiting in the wings.

The blips you see in the power/torque curves down low are also on purpose. I was DUMPING tons of fuel in right there to be safe on the dyno. In reality, the car would never be operated in the same manner on the street as the dyno (i.e. high boost pull lugging the engine from low rpm) so I left the fueling this way to be conseravtive. This turbo hits hard and fast so I want to stay ahead of it.

Ignore the up and down peaks at the end of the run. Those are when the run was over and the car was spinning down.

Also...this run was on pump gas with the alkycontrol.com progressive kit. No race gas needed

 

Yeah...that was frustrating. There was seeingly alot of noise on the dyno that day as we had pickup problems with quite a few of the cars.

But, I can convert the numbers for you guys here from my datalog.

The run ended at about 6900 rpm, which would be 95 mph on the plot. So, the ratio is roughly 73 rpm/mph.

Another interesting note......

On the dyno, the car took 2 seconds to spin the drums from 60 to 95 mph

 

SC61.....he was inspired by the yellow skittle

 

holy shit sleepeR!!!!!!!!!!!!!!!!!!!!!!!!!!!!


good job man!

 

Same turbo that you told me to get like a year ago

Precision SC6152S with the ported shroud TO4S compressor housing. This thing rocks.....massive difference compared to the TO4E 50 trim I had on there before.

 

Larry,

how did it feel to turn on the A/C and drive 15 miles home in the beast

 

Pretty dang nice I sweat my butt off in that 90 some degree dyno room all day.

 

Yeah......I liked what I saw on Sean's car at that SRT4 dyno event you hosted last July
