The Dodge Charger RT in the article is 10.5 to 1. So I want to ask a question. What if you use 87 octane in your 12:1 compression Mustang GT religiously and drive it hard even on hot summer days? I have to think that there must be some sort of longevity issue that will arise at some point...

The F150 is interesting. So using 87 octane lowers the boost down to 16.2 psi. Imagine if I said I was going to build an engine for boost and run 87 octane and force 16.2 psi into the cylinder with turbos. Would you tell me I am crazy? The F150 pickup did lose add a second and lose 4 mph...

And lol at the BMW making 617 to the wheels on 93 when that is what BMW says is the flywheel number. No wonder those cars can accelerate so quickly. But, no, they did not risk putting 87 octane in this car. Whew! You can pick these cars up now with less than 50k miles for about $55k

Imagine 18.5 psi forced induction but only getting a total of 190 hp and 179 lb ft of torque!

krisk, For what it is worth I was quoting a post about the other system coming loose, not the rear camber arm.

Which camber plates did you install?

You say "best," but do you need/want more than that? I guess I assumed that even at -2° you are starting to hamper the ability to apply throttle early coming off the turns in that 500 horsepower beast. Wouldn't that problem just get worse the further you go?

Looks small. I guess I was just more concerned about what a 20 pound chunk of metal would do in a collision (which is also lighter than I thought it might be).

How do you know when it is the right time to go from just putting the car in Track Mode to holding the traction control button until the dashboard says "AdvanceTrac Off" and hitting OK?

You drive around with a floor jack in your car?

(1) Caster camber plates would be my first mod. (2) Stickier tires in a 295, 305, or 315 size on 11" wheels would be my second mod. The same size all around. 18" or 19" - 18 would give you more tire choices, but these days 19's choices are catching up. I recommend you join...

And I do not know that it was topped out as against air resistance. That is just the speed they hit before they had to brake to make the turn. Maybe watching the video again we could figure out if there was more, or not. EDIT: Nevermind, the speed is not displayed on the video, so no way to know.

Specifically, I think it was this one: https://kpmfuelsystems.com/product/kpm-800hp-track-pack-fuel-pump-module-oe-replacement-s550-s650/ Which is also what Ford put into its track experience Dark Horse cars.

Nice result on 93, and the torque is high at any rpm where the car will be at full throttle with a 10R80 automatic

Steeda has a video of an S650 hitting 176 at Daytona after a Palm Beach Dyno tune with the speed limiter removed and rpm limits raised.

Is there video of that from inside the car?

Out of curiosity, why did you replace the rear studs?

Which ones are you installing?
