Just a reminder, I'm looking for anybody who does not have the stock tires/wheels to post their G-force max forward acceleration from the dash display (after resetting it) on dry un-prepped asphalt, temperature they tested, as well as their rear tire size/model. Mine was 0.80 G forward with my...

Bought my roush S/C PP GT mustang about three months ago. So far so good. I can't tell the difference in driveability from my last '15 PP GT car which I had for 2.5 years except that this one accelerates faster. Note that when you accelerate faster, you expect the rear wheels to slip more...

I've got about 2500 on mine, and really am considering RST or RXT. I heard they both make noise at idle (under 1500 RPM), so I'm looking for a better alternative that doesn't make noise. I heard the RST is very much like a factory feel, but the RXT is jumpy and uncomfortable to use. I also...

Did they hassle you on the new free clutch install on your whipple? When I needed a new clutch on my old '15 GT (no SC installed), it was a horror story since they said I had more than 12 months or 12K miles and they only replace the clutch for free if it had less than 12K miles/12mo on it. I...

I speak from experience that if you buy a new GT that the dealer already had supercharged, you can find one that will agree to give you the full bumper to bumper 3yr/36K warranty (including engine/transmission). If you do it yourself (or possibly even later after the car is bought but through...

"As far as what the tires will hold with G-force... take the car to 60 and slam on the brakes" That is a good idea, but requires some knowledge of the front tire sizes also. So if anybody wants to try to post braking g-force, post both your front and rear size/type tires and the temp. It kind...

I'm not sure if there is some optimum weight you can add in your trunk to get a better 0-60 or 1/4 mile time as adding more weight generally increases the time it takes to accelerate to some distance. If the rear tires stick better, but the car weighs more, there must be some 'sweet spot' where...

I read somewhere that the goal for a RWD car is to transfer most of the weight on the rear wheel during acceleration and very little weight on the front wheel. This way, you get the best acceleration since all of the car's weight is pressing down on those two rear wheels. When you enter a...

Hi Sigintel, "Always insure front hydroplanes first so you can back off speed in a straight line and resume ass haulage without a spin into a bar ditch. Wider than 255 will bring hydroplane speed way down or need new rains once tread depth below 5/32. If its dry enough to run >245 width, youll...

Dodge Demon tires: Nitto NT05R 315/40R18 Dodge demon weight: 4280 lbs. and has 808 (91 octane) to 840 HP (100 octane) at the flywheel. Of course, the 0-60 times they publish are impossible to get on a normal street. They sometimes include a rollout where they don't count the time until the...

Found this video of a Lambo Aventador (700 HP 4WD) vs Mustang Roush phase 2 (727 HP RWD): [ame] A lambo was on my list of desired cars, but a used 2004 lambo with high miles was still 2x the price of my brand new supercharged GT. I heard it costs $1250 for an oil change. I think I got a...

The 2018 zl1 camaro with 650 HP uses goodyear eagle F1 supercar 3R summer tires. Anybody have experience with these? Note they only have two sizes, 305/30ZR19 and 325/30ZR19. I'd keep my 295/30R19 MPSS on the fronts and replace the backs with these. The 650 HP camaro gets a 0-60 of 3.5 sec...

"I've run the MT ET SS and its decent in the rain, not as good as the NT555R, but you will not die driving it in the rain" Thanks CMY for your response! Yes, I really am trying to not die in the rain as it rains 145 days a year were I live...

I agree with you that the right tire won't slip in 2nd as well as not slip off the road in mildly wet conditions. You know, I still watch Dragon Ball Super in Japanese when it is played every week in Japan (our Saturday nights). I should have outgrown it since it's a little kid's show and I've...

I actually used to have a yellow '15 GT PP car but traded it for the dark grey supercharged '17 GT PP metallic one I have now. Naples is a long drive, but thanks for the invite! Google maps says 1 hour, 41 mins. I probably still have several months on the tires I have, but I'd like to buy a...

Thanks for the link cobo_pro! Your tire was ranked at the top of the 5 they tested. That CECS tire looked about the same and slightly better in wet conditions. I can't believe they found a 0.95 and 0.94 G on those tires, but maybe their G-force meter is more accurate than the ones in our...

Just for reference, I found a new 2019 corvette zr1 is coming out with 755 HP. Many Mustang turbo/super charged cars are probably around that HP now (at the crank) on 93 pump gas. They are using Michelin Pilot Sport Cup 2 335 wide tires, probably the same ones used on the Z06. I found these...

Hi Cobo_pro, can you reset your accelerometer and take a new reading of forward acceleration on dry asphalt (not a racetrack) just before the tires slip with your MPS 4S and let me know what it is and what the temp was? Feel free to try in 1st or 2nd when the weather is as hot as possible and...

Unfortunately, at 40F you probably don't get 'good' traction on any tires. I just happen to live in South Florida where the temperatures are generally 70F to 95F most of the year and I am close to sea level so I get slightly more air pressure. I suppose if you posted the forward acceleration...

"NT555R DR should last over 5K" Thanks, I would consider them, but they don't make a 19" tire and my wheels are 19". "No street tire will hook" Tire choice is one of the most important factors on a FI GT in my opinion. Better tires (softer compound) = better grip. At some point, the...
