Still cool to see what can be done.

Please let us know if it works better.

😢 C85 at 2:35 on video

You lose something, though, right? Something more than a check engine light trigger, I mean. Or is it only checking on the working of the catalytic converter and sending a fail code? It does not tell the engine to do anything at all?

Yeah, I got it, but I assume anybody buying the four cams and the Cobra jet are also going to add headers, E85, and, oh, I dunno, maybe a tune? 576 at the wheels is kicking. I wish you did not have to lower the engine to fit the manifold. You have to lose the strut brace, too. But this...

Thanks, even if it is disappointing to read.

Your car, your choice, so I am not criticizing, but I am curious why you would want to install narrower front wheels than stock.

Why is the tuning comment in there? Is it still not tuned? Will tuning cure the CEL issue?

2.89 mph And yeah, that 3587 difference is like adding a very low boost. I think you are correct about another 2 mph.

All that is required is a tune. In other words, the same thing you are already doing, but specify E85 in addition to your headers. https://www.mustang7g.com/forums/threads/e85-tune-results-on-stock-s650-mustang-gt-5-0.169947/

Interesting. This is where I found the electronic sound (I presume) jarring.

Put the video on Youtube and you can just post the YouTube video? 3 days, ouch. Glad you got it done! Are you considering E85 and a custom tune or no? (is E85 a thing in California?) UPDATE: It looks like they have E85 all over Huntington Beach: E85 Huntington Beach but those prices, ouch!

What sort of subtle change?

What are the noticeable results?

I don't know how they ever pass at Monaco, for instance. The entire track looks narrow, tight.

I am having trouble imagining what sort of trailer I could load my Dark Horse onto without tearing the front splitter off.

:facepalm: The minimum weight including driver for 2025 was raised to 800kg. That's only 1,760 pounds. 840 horsepower plus 160 horsepower from hybrid boost = 1000 horsepower. So 1.76 For a 3950 lb Mustang to have a similar power to weight ratio would require 2,244 horsepower...

With ring gap on the stock engine, I am thinking 30 minute track sessions are going to close that gap sooner or later on a summer day.

GM engineers ought to focus on active aero for next year's model ZR1.
