Elite 71mm Review (log information)

As many of you know, I recently received my Elite 71mm low pressure turbo. Well it's already on the truck and I have close to 200 miles on the truck testing the new setup. All I can really say at this point is.....WOW! I am so pleased with my new setup. There is nothing that I have found that I dislike about the new setup. We did run into some issues with the POS Diamond Eye downpipe that is on the truck, but powerstroker67 is taking care of that little problem this coming week by sending me one of his ceramic coated downpipes. The turbo spools quick, makes some serious boost, and sounds wicked. I didn't think it would have the whistle that it does under load, so that has been a huge bonus. Always nice to get a little extra than you expected. With my current setup (dynoed 594 on Dunbar's last March), I can definitely see 30-40 HP being gained with the 310 tune. I don't want to say my truck will make 630 HP, but seat of the pants it feels so much stronger than before.

Now to the data logs....that I unfortunately forgot to monitor throttle position percentage, so I can't really say how hard I was in it. It was 54* and very low humidity when I performed these logs. Perfect weather!

Data Log 1 - acceleration from 34-72 MPH at what I would consider between 1/4 and 1/2 throttle.

Max EGT - 1,072*
Max rail pressure held - 25,400 psi
Max boost - 53.7 psi
Max back pressure at max boost - 52 psi
Max EGT at max boost - 1,066*
Max back pressure - 56 psi
Boost at max back pressure - 30.1 psi
RPM at max back pressure - 2300 RPM
MPH at max back pressure - 38 MPH
Rail pressure at max back pressure - 21,950 psi
EGT's at max back pressure - 756*

Data log 2 - acceleration from 68-85 MPH at around 3/4 throttle

Max EGT - 1,128.6*
Max rail pressure held - 25,600 psi
Max boost - 54.6 psi
Max back pressure at max boost - 60 psi
Max EGT at max boost - 1,047.6*
Max back pressure - 60 psi
Boost at max back pressure - 53-54 psi
RPM at max back pressure - 2170-2240 RPM
MPH at max back pressure - 78 MPH
Rail pressure at max back pressure - 24,600 psi
EGT's at max back pressure - 1009-1050*

Data log 3 - acceleration from 65-92 MPH with the pedal to the floor

Max EGT - 1217.1*
Max rail pressure held - 24,900 psi
Max boost - 55.5 psi
Max back pressure at max boost - 59 psi
Max EGT at max boost - 1,068*
Max back pressure - 65 psi
Boost at max back pressure - 53 psi
RPM at max back pressure - 2580 RPM
MPH at max back pressure - 91 MPH
Rail pressure at max back pressure - 24,700 psi
EGT's at max back pressure - 1208*

If there is anything anyone else would like to know, just ask. I can look it up on the data logs I took if I have that particular PID logged. The most boost I have seen was 56 psi and the most back pressure I have seen was 66 psi. This was pushing it as hard as I could from a rolling 70 MPH. Hopefully this review helps others on the fence about a turbo setup and also helps those looking for hard data using a big low pressure turbo matched with the stock VGT. I will post some pictures in a bit when I get them uploaded to my computer.

Thanks,

Jeff@Spartan

Industrial fuel line clamps that didn't do a damn thing for my harmonic fuel line issue and got in the way of the heat shield....which is where Ricky proved to be handy! LOL

Nice write up Jeff! I will have my truck back this week hopefully. I am excited about the turbo whistle. I miss the whistle that the powermax made on my old 06.

I can't really tell if the exhaust sound has changed. It doesn't seem like it has under normal driving conditions. At WOT it seems much throatier. The whistle is definitely noticeable in the cab under load though. I love it!

Nice!

Jeff, how are you monitoring the back pressure psi on the Dashdaq? I dont see it anywhere...

It's labeled as EP, Exhaust Back Pressure (absolute). It's under Ford Specific parameters. It reads back pressure with barometric pressure added in. Rule of thumb is to subtract 14 psi from the number you see on the gauge.

I think it would be a great setup for towing! You can't beat good spool up and cooler EGT's when towing.
