Pretty excited to share some info and video about my recently finished (sort of--are they ever finished?) TT build on my 18 Mustang.
Car is running a semi custom TT kit from CXRacing. I had to rework (cut, re-weld, reshape) a lot of the hot side of the "kit" to fit around the 10r80 in this car. On the cold side, i upgraded the upper IC pipe to 3.5" for better MAF resolution and ease of tuning. I had everything powder coated wrinkle black for a low key look.
Absolutely love this car. For the first 1/4 mi shake down, it did decently well. I would have loved to break into the 9s my first time out, but wasn't in the cards last night.
This pass was on 8 psi boost. I tried to turn it up to 10, but the track just wouldn't hold it with the 18" tire set up i was running.
Anyway.. not a lot of s550 content on this site, so thought I'd share.
Please excuse my son's excitement at the end of the video hahaha.

139 is good, but was hoping for more .. you know how it goes hahaha. Fontana is a SUPER stingy track.
Running e85 with ID1050x's and a Sai Li return fuel system.
Pretty damn good pass for shakedown run. How do you like that Sai Li system? I have been wanting a return style setup, looking at his and the JPC one for E85. FWIW I have ID1000s.
Injector duty cycle is still low. I don’t think the car is making much more than 750 or so, so should have some room still.

Get that thing on a dyno man! I know they're just tools, but I'm curious. Because I wouldn't imagine me going much faster with 815/833. Like 141-142 max.
Jeez, I need a 10R80.
Y’all both need a dedicated wheel / tire package!
solid shake down. What is your suspension setup?

I'll def schedule dyno time once im finished working out the kinks. The track outing definitely exposed some. I ordered all of the stainless tubing and bends i need to fab up a true 3" exhaust from the turbos back. That will be next weekends project.
I have been running 3" after the turbos to about a foot before the pumpkin... at which point it necked down to 2.5" into the factory mufflers.
Thats all going away which will free up some more power.
Im half way there lol. Ive got the fronts.. .just need to line up some 17's for the rear and some ET R's.
Would be nice if ford sold a SRA swap for these s550 cars. Maybe make it for track use only (the S550 Cobra Jet is solid axle) . SRA would probably drop a good 200lbs. Making these newer mustangs about the same weight as the s197 while being more aerodynamic.
