FP Red vs. Stock Turbo, E85, stock longblock
FP Red vs. Stock Turbo, E85, stock longblock
Hi all,
Just wanted to share the results of my latest dyno session @ AMS. I was made aware that there are not many apples-to-apples comparisons of the FP Red to the stock turbo on a bone stock longblock (with no other factors changing i.e. adding cams), so hopefully this post will shed a little light on that subject by providing what is as close to a back-to-back comparison with as few factors as possible changing.
Modification list:
FIC 1100 injectors
Walbro 255
Artisan intake w/AMSOil filter
Artisan turbo-back exhaust WITH HI-FLOW CAT (for all the haters)
Artisan "hot side" intercooler pipe
Bushur "cold side" intercooler pipe
GM 3port BCS
(I'm sure there is something I am forgetting...)
Now, a few quick note sbefore we get to the charts:
1 - The original E85 tune on stock turbo was performed 2010-9-7, and the FPred tune done 2011-1-31. There is a chance that the gasohol in September was of a higher EtOH content due to blending schedules in my region-- I am not sure if it was real-deal E85 or something less. The most recent tune is on the winter blend, which could be as little as 70% EtOH. Draw your own conclusions
2 - Hardware wise, the car is exactly the same for the go-fast bits, however in the interest of full disclosure, the stock longblock I am running today is not the same stock longblock I was running in September. Nonetheless, both are bone stock. Also, I now have a HDSS clutch on the stock flywheel which I did not during the initial tune (it started slipping about a week later :P)
3- Obviously, the climate has changed, which is why I will post both corrected(SAE) and uncorrected numbers for the FPred. I think (not 100% sure) that my stock turbo dyno plot is with SAE correction (maybe Chris or Mitch can chime in). Otherwise, it was the same dyno. Again, draw your own conclusions.
Now, the charts! :

Corrected FP Red dyno, 2 back to back runs:
Corrected(I believe) stock turbo(plot#1) vs. corrected FP Red(plot#2):
Sorry that last one is a bit hard to read... copier at work only scans black and white.
Very happy with the numbers and the way the car feels (what lag?). Back in September during the original tune, Chris@AMS told me their Mustang consistently read 8% lower than their old DynoJet across several cars. Using this multiplier and the uncorrected figure of 395whp/352tq, you get 427hp/380tq... not that numbers other than a timeslip mean anything

noticed the pics are down... fixing ASAP -- my domain expired :P
edit: looks like the domain will be down for a bit, so I uploaded the sheets to the first post. enjoy!

nice numbers. car must feel great. one thing i noticed is that your boost tapers down to around 22-23psi. i would have expected that turbo to hold 28 psi all the way, if not maybe a taper of around 1-2psi.
A- I have a stock wastegate actuator
B- This is a conservative tune
C- I could see fuel(E85) supply being an issue... I'm on FIC 1100s and a single walbro... not sure how close I am to static open on the injectors.

If I'm reading it right, you're making MORE power and MORE torque pre 5250 on the stock turbo. To me it looks like the FB Red only gained you ~40hp on the top end and lost quite a bit on the low end... Looks like the stock turbo would've been more fun haha
He just has to run more boost to make it more fun...
The red is a different fun than the stock turbo, not the same punch in the face, but up top it just pulls and pulls to redline.
But with 28psi+ on the red the fun factor far exceeds the stocker.

If someone wants a more "fun" turbo, then a green is more their choice
In order to make setups as "fun/worthwhile" as others you need to pick a turbo that you will utilize.
Derek isn't fully utilizing the red on this setup and without doing that it will be hard to compare the two.
I know exactly what you are talking about.... though some people don't, and make funny comments like "the stocker would have been more fun" (though this turbo isn't even beginning to do work yet... lol
