Are 250/100ís going to make the 369 spool quicker than the smaller injectors being tested here? Iím hoping so. Iím also going to be using the Irate manual shift box so I can unlock the converter easily when towing and under the turbo. Thoughts?

IMO the debate would be weather bigger nozzles really spool turbos faster... because body size has NOTHING to do with spool up. Body size is simply the maximum amount of fuel you will dump at WOT on a max effort tune.

In our testing so far... smaller nozzles tend to spool the turbos a little faster. Now I know some people have spent countless hours live tuning bigger nozzles and claim they spool faster with cooler egts according to their "butt dyno". But that has not been our experience while working with some of the best tuners on the market sending "email tunes" and testing back to back on our dyno.


I also know some guys who have replaced 200,000 mile old stock tired injectors and went with larger injectors and spooled way faster... but that is kind of apples and oranges

Will be finally getting the tow truck on the dyno with 238cc/80s and the s364.5, it has been running the setup for the past 4-5 months. Excited to get a s366 /s369 on it with the 238s/80s compared to the 205/30s.

Did you do tests with the 205s and the 366?

We did not do the s366 with 205/30... customer jumped up to the 369 because that is what everyone "swears by", saying it tows amazing and is the perfect setup. NOT TRUE FOR HIM. That is why he dropped back down to an s364.5

The 238/80 and s364.5 truck is a little smokier and harder to tow with, he had to be much more careful with EGTs and throttle position with towing, but did have more towing power over the 205/30 but had to be more careful with it. That was after many email tune revisions. We were luck enough to have Andrew Arthur (the best kept secret in 7.3 tuning). He was able to live tune the truck and pull a lot of fuel out of it and got it to run much cleaner... but did lose a little power.


We do have a dyno graph from before the live tuning. Here is an all out race tune vs tow tune with 238/80 and s364.5

Am I the only one who hopes kc turbos creates their own thread or web page with a bunch of dyno sheets they've collected. Looking at dyno graphs from everything from stage 1.5 to 300/200 has been extremely helpful.

We have thought about trying to make some sort of interactive graph/app/web page where you can select each setup we have ran and overly them.

Its easy for me to do from my computer, then screen shot, then post the pic online... but it literally turns into 1000s of options.


I live for this stuff... main thing I love about my job is learning all the differences between setups and turbos. It really helps us to provide a better service to our customers when it comes to get them exactly what they want/need.
