Reliability after supercharging

Nitto 555R’s for the win

Reliability is a case by case scenario and dependent on how the person drives it. Mine is a 16 with over 30,000 miles on my Whipple so it may not answer your direct question of an 18/19 model year. I have had zero issues and my car is daily driven along with about 6 road course days a year. I am not gentle and run it to its edge on track and when it’s daily driven, it’s just driven pretty much as a regular car with occasional spirited moments. I never have to add oil between oil changes and I do run a catch can.
Back to more on your topic, I don’t run my strut brace and have never noticed a difference as most don’t but there are plenty out there that have modified them to fit so that’s an option. The most important upper brace is the k-brace and much more functional and can be added if your car didn’t come with it. On a side note, the Roush SC cuts this brace on the drivers side (among other modifications to the front engine cover as well) which is asinine and the Whipple does not.
You’ll get plenty of opinions on tire brands so I’ll let you get hit by that. Wheel size and offset also have a contributing factor to that. Other contributing factors that can help out a lot is differential ratio and transmission gearing plus suspension changes and building it correctly for your intended use.

You don't need to cut the k-brace on the 18+, maybe you do on the previous years. The lug on the timing cover gets cut down so that the blower drive can use the 1st sheave on the damper. This reduces stress on the crank snout.

That’s good to know about the k-brace on the 18’s and up. Poor assumption on my part.

You'll probably be able to pick up a STB from Ford once the new GT500 debuts, shock tower mounts are almost certainly going to be identical. Worth checking out.

I've got 14K on my '18 with about 8K miles with the Whipple on it. I haven't had any issues with it.

 

[DuRsT]

I put 25k on my Gen1 Coyote with a Roush blower on it with zero issues.

I loved the reliability and all that, but I did hate that you couldn't hear the blower at all. Would have preferred some amount of whine.

I have about 18,000 miles on a 2018 gt a10. It’s been whipple supercharged since about 4,000 miles. I use it as a daily. I’d be lying if I told you that I don’t worry in the back of my head about reliability but mine has been perfect so far.

As for the STB, I think you’d have to be pushing the car really hard and have lots of experience pushing to the limit to notice it. I don’t so I can’t tell a difference.

I’m running the stock ps4s tires and they won’t come close to hooking. In cool weather they won’t hook until 5th gear. In the heat they’ll sometimes hook in 3rd but usually not. Forget wot in 1st and 2nd. As far as I can tell they’re about as good as you can get short of a drag radial, but I’m all ears for suggestions for a DD.

I just got my 2019 PP1 a10 and looking to do the roush too. From what i have been researching getting wider wheels helps with grip i plan on going with the P51 19x10 front and 19x11 rear. should help.

Wide is good but the tire itself matters more. For a daily check out the Nitto 555r. Will hook but won't be as deadly in the rain as some of the MT or other options.

555r isn’t available in 19”

Roush supercharger going on tomorrow I got a great deal from Beefcake racing on a 4th of July sale. I’m gonna run with stock tires for a bit and then get some big boys after I melt them LOL.

yeah i fucking hate it... should have looked at tire options instead of picking wheel size first.

I'm stick with nt05r's for the 19's... I don't know of any other viable options with 700 wheel to keep the power down

Those hook but gotta be super careful in the rain.

I spaced the 19" availability part when mentioning 555r my bad.

I’ve heard good things about the Firehawk Indy 500, but never tried them so...

I have 275/35-20 square on my set up and they hook up and handle great. I only have the e-force 2300 stage 1 kit but I was still amazed of the amount of traction I get in 2nd gear, dont get me wrong they still break loose all depending when and where I get on it. I'm sure that will change after I get off the EB 93 tune.

 

[TehEno]

Could try the Toyo 888r's? But I think the widest for a 19" is 305.

They offer a 325 and even a 345, but the aspect ratio is 30
