Going barefoot is one option. Another is to get a slightly higher profile tire, say 245/55 over a 245/50.

The fact that it's stronger doesn't mean they didn't use less of it to save on weight. We will see what it can hold soon enough, I am guessing something else will break first, money on the axle or tranny.

That Hellcat was literally a sleeper, 0.6 seconds reaction time. Edge left -0.07

Here's a good launch... https://youtu.be/Eh-t6gN37tQ

PTU is slow to send the power back and when it does, I feel it doesn't send enough. So the car is basically 70% FWD and that's a lot of power going there.

If I understand this right, the wheels will come off on the first full power 1-2 shift ehehe My car hops on the first shift that leads me to believe there is a ton of power at redline. Will stay tuned. Meanwhile, I set a new stock record for those who still have their warranty in tact.

More PSi? LMS race v3 is pushing 21 psi, can the block handle that much more? Just curious. I'm guessing more power is going to expose more weak points. For just the tune, the weak point is putting all that power down.

Car And Driver says 3.5 in the Explorer ST, if it's series 2 I might just upsize and tune it to 600hp :-)

2015 Handles 450hp and over 500 tq just fine, at least at 18000 miles.

RMM introduced quite a bit vibration at idle for me when on winter 21s. Summer 20s much softer and acceptable level of vibration. It eliminated wheel hop on 21s and reduced a bit on 20s.

The car has 12.6s in it if I wasn't hopping, I have yet to max it out :-)

2500 might be too high without springs on all seasons, 2k even might be ok. I used to spin stock 265s no tune.

Well...get a Livernois tune if your launch was the best the car can do. Traction off in Sport mode? Very curious, too far from me to see in person. Run em again on video.

K, Ford is not Audi and S4 is not an Edge.

You need a driver mod :-) Traction off, foot on brake, foot on gas, let brake go. No need to go get new car :-)

Hop hop

Think you will need race tire as opposed to lower PSI, I tried as low as 24 psi. Hop at start and hop going into 2nd gear.

What's the plan for wheel hop?

So what you are basically saying is that your admin went into god mode. Ever hear of an appeal process, or the concept of checks and balances? I am done, thanks

www, you race too?

I am running 20s and a summer tire. Grip was a bit of an issue and the car did hop.

Xtra, I did remove spare tire, not the jack, added torque wrench and had a baby seat in the back. I ran both 93 and race tunes. No exhaust, not sure which rpm I launched at. I did a basic log, join my FB group, happy to share the details.

My only power adder mods are LMS v3 tunes, 93 and race plus KN drop in filter. 93 fuel gave me a 13.1, then magic octane booster got me the 12.79. all other mods are aimed at consistency and reducing wheel hop.
