Well I suppose I should have made it clear that I was looking for 4 lug hubs instead of 5.. Well the used set I found where 5
oh well! Good thing I have a machine shop and some very experienced co workers at my disposal! I ended up throwing some ARP bolts in there for good measure. A plus to this is if I decide to change my rear end up in the future I now have the option to run 5 lug.

I run an auto so a bit different but that ramp rate should hook about anywhere on a decent tire, being IRS I don't know
You are around a 6psi/second rate there. Mine will put that down like a bracket car any day on that rate, 8-9 is where I would ride the edge and make it work more times than not, 10 or over nope
That is ramping from 4psi to whatever overall I wanted. It would hold any amount of power I could throw at it as long as the ramp rate was proper and in the ranges stated

I've been following this build for a while now, and never posted.
I love it. I'm hoping I can make it to the Mile and can check this out. Not to participate of course.
Good luck man!!

Well **** me running. I just did a 4th gear pull @ 21psi and E85 and Jesus this car is fast. It was pulling like a freight train sideways at 100+MPH!
Duty cycle on the injectors was 60% and I was consuming 800lb Hr with dual 044's and 160's I think that puts me around 1000? Not sure but it felt like it.

That sucks. I got shot down for the runway battle thing in Dallas so I feel your pain. No seat time though? That's a shitty excuse! I'm about to battle some of the fastest street cars in the country with an old *** car with 4 passes and fresh un dialed in E85 tune under my belt
it's all about having a good time.

IMO I'd like a smaller sidewall tyre for speed stuff
I've had various tyres over the years, and some of the taller sidewall tyres can feel unstable at speed.
The Hoosier DR's I was using 255/50x16 have been the worst in that respect. Strangely also the worst gripping at the top end.
I had to back out of 2 1km runs last year due to excessive wheelspin around 170-175mph with them
Swapped tyres to my road 235/45x17 Toyo 888's and they gripped far far better at the top end ( although was still breaking loose a little at 175mph ). Also perfectly stable. Still no real grip below 130-140mph though
I find it best to get into a high gear sooner rather than later, and let the torque do the work.
Despite lack of grip and stability, the same Hoosiers are the tyres I've run my best 1/4's on airfields...which is strange. But they were run at very low pressures to get them to work.
Actually debating what to buy for this year, and thinking the 245/45x17 M&H radial sounds like a good option.

Stay with the mickey . if it was a mile pull maybe think twice but not for this
You won't find a better tire for traction on rolling street type stuff
There is no reason any 1000hp car should be spinning above 100 on a mickey
