Default N54 6266 dyno session - 06-08-2020, 10:02 AM

Just looking for some feedback on logs, going port injectiong in the next couple weeks and want to have my current setup as dialed in as physically possible prior to my next step in power.

Mod list

Custom bef twin scroll maps that ive been adjusting over time.

Consisting off vanos timing changes to enable faster spool. Fueling, lean spool disabled. Ignition timing adjusted for pump and e30 maps.

6266 g2 1.15 ar
Jp workz top mount manifold
Walboro 450lph
Custom 3" t304 turbo back
Vs catch can
Mfactory flywheel with spec 3+
Upgraded engine and trans mounts
3.5 bar map sensor
Custom charge piping
Vsrf 7" HD intercooler
All logs done on map 3 20psi

Car put down 520whp on a mustang dyno, Im content with this for the time being as the intercooler and hpfp are nearing there limits. Shop owner advised that this dyno typically reads 13 percent low. Dyno run was on e30 blend fuel.

I've had some issues finding all adjustment variables on dialing in the car as far as the jb4, so please let me know if you find anything that may be incorrect.

Logs were completed with engine timing set to 1 to view knock feedback, Not sure if this is false info.

IAT rises to almost 170f on the dyno with a barrel fan, its clear to me the volume is rapidly outpacing the intercooler. Considering uses a devilsown meth setup I have laying around from one of my other cars with a small nozzle just to keep iat down. Ive heard some negatives about uses this with port injection, any opinions?

Having some issues attaching the logs. Will follow up with a second post.

Thanks!

both dyno logs on e30 blend.

pump gas log is a quick pull on the street after altering some fueling settings within the base map.

iats crazy high.

My logs of a plazmaman intercooler in 31 degree c 88f ambients dont go over 115f cruising.

Start of pulls are generally around 110f end of pull 90f repeat after repeat. Thats without meth or water.
170f bloody high and robbing you some hp.

Thats on 20psi wot runs but e85 fuel compared to 93 fuel.

Typically I see about a 10-20f rise above ambient temperatures on the street in 3rd, Im fairly let down by the 7" hd vsrf. Im thinking that the fan setup at the shop was not helping the situation. Definitely my first priority at this time!

That IAT rise I’d attribute to a few things.

-stagnant air / hot Dyno room
- inadequate fan
-VRSF 7in - ok for stock Turbos, but has shown to be very inadequate with hybrids & single setups

Logs don’t look bad, Heat zapping a decent amount of power for sure

Definitely the next thing on my list Dave!

A couple of questions as I dive deeper into my flex fuel configuration with pi

Pin 2- flex fuel signal wire to jb4? I assuming that this is the case. Saw a fuel-it video that mentioned pin 15 but I'm guessing that this input has moved to 2 for the port injection.

I am working on configuring a full flex fuel setup which consists of mhd to handle the timing adjustments and the jb4 for fuel scaling etc.

Based on my research the only way I believe that is currently possible is to take the signal from my flex sensor and branch it to a motiv flex fuel box in addition to the jb4.

Thanks!!!
