KC Turbos has decided to venture into the EcoBoost world. For those of you who don’t know us… we do a lot of Powerstroke Performance. What we like to do is buy a 100% stock truck, test tunes, test turbos, fuel options, etc… then we develop our turbos around that data. It takes a while and we usually do it behind the scenes, but we decided to post it all up on the forums for those who are interested in following along.
.
Today we are posting up results from our 2016 2.7 rcsb 2wd. We got it up on the dyno for some baseline tuning. We assume the truck was stock, but could have had some sort of tune in it. We decided to go with Gearhead tuning… we have worked a lot with Matt at Gearhead in the powerstroke world and he has really put in a lot of time on these ecoboosts.
.
Let me start off by saying these trucks are a BLAST to drive. They are so light and nimble, we were very impressed with what the 2.7 ecoboost was able to put out with just a tune. Everything else 100% stock.
.
I will post up 4 dyno charts. Chart 1 is just the HP numbers. Chart 2 will be tq and HP but gets a little messy with so many dyno runs on the same graph. Chart 3 is just stock vs highest tune to show the gains. 4thchart comparing a tuned 5.0 to the 2.7 ecoboost. Stock with a tune the ecoboost wins hands down.

Chart 1, 2, and 3
Red – stock baseline number (ran with 91 pump gas)
Light Blue – SCT - 91 (ran with 91 pump gas)
Green – gearhead AO tune (ran with 91 pump gas)
Orange – Gearhead AO (ran with 93 pump gas or e15 added to 91)
Dark Blue – Gearhead e30 tune (ran with 91 pump gas mixed with e85 to get e30 ratio)

4th chart
Light Blue – 2017 5.0 coyote tuned on 91 octane
Green – 2.7 eco gearhead AO tune (ran with 91 pump gas)
Orange – 2.7 eco Gearhead AO (ran with 93 pump gas or e15 added to 91)
Dark Blue –2.7 eco Gearhead e30 tune (ran with 91 pump gas mixed with e85 to get e30 ratio)

 

Pretty dang cool Charlie. Are these turbos variable geometry?
