There are lots of reasons

If it was actually putting down the full 1000hp on an airfield at only 100mph, I'd be very shocked if it retained grip.

And all airfields are different, surfaces are different, weather conditions, vehicle dynamics etc etc

I have used both Nitto and MT DR's in the past at speed and both have been stable compared to the Hoosier DR's

 

Only downfall to the mickey is it will feather up, then you are on marbles

But small burnout to clean and u won't beat them with a fresh surface

 

Show me something to back claims

I have plenty of data showing what is capable

That is all I did this summer testing... Rolling hits on asphalt

 

I have been 3.42 100-150 and 4.05 60-130 on 275/50-15 mt radials...... On everyday blacktop asphalt


This is on certified vbox runs...

Straight as an arrow, zero spin, like a Sunday drive

By 110mph much more power than car saw to run 163 in 1/4

 

I believe all your data is ramping in boost and hence power so traction is not overcome.

So it's highly doubtful the full 1000hp is being applied to the ground at 100mph. Not even close.

 

Where i would probably feel a little more comfortable with a 26" tire i think ill be ok with a 28". After all this tire is a radial and this particular race is on a prepped drag strip ( a very good prepped dragstrip) With the short distance of the race i think the taller tire will actually help me as i should be able to utilize my 3rd gear a little more.

 

Not sure why you feel that way. The 100mph range is when i am at peak boost/throttle/fuel consumption. If its not making 1K there than where the hell would it be? cutting the tires loose at 100MPH in a 2960lb car making 1K isnt a phenomenon.

 

Yes your right I have no idea where I peak boost at, no way to tell from a log or for the fact I am entering the ramp rates


Please look up my times on other boards and you will see where I sit... And the lack of other rwd stuff close to my times on the street


I can send you my vbo files if you wish... You can look at exact coordinates of where this happend and what highway

 

Ah right, I thought you were referring to a Texas mile or similar. Didnt realise it was a prepped track you're racing on.

And I know breaking the tyres loose isnt a phenomenon, I can do it with ease way past 100mph although I'm around 3700lbs.

But ZBrown is achieving excellent results with his, with normal tyres on normal roads but he has spent a lot of time dialing in and ramping in boost to allow it to grip.

 

I've already seen some of the info in other threads and yes the times are excellent, but as said you've spent a lot of time dialing in the boost/power/trans/chassis so it will retain grip on the street.

 

All I did was test this **** this whole summer. The mt Dr is king, I couldn't get close to touching my DR times even with full slicks

Here is one of the high power

I am targeting as fast as possible from 60 on, I am not entering my ramp in off of gate(4psi) till 30ish mph

Phone is taped to the steering wheel, look at all tat steering input from the instability

 

Its all about power delivery. Completely

I could be rolling 80 and I just let 12psi slam in I'd roll them

That video above I am around 24psi from 110 on

18 the the car ran 163 on

 

On local airfields I've tried ET Streets, MT DR's and Hoosier DR's, all same/equivalent size

For me the Hoosier DR's worked best, ET Streets were the worst.
Not really a surprise as the wrinkle walls are really designed for a prepped surface.

But as said, the Hoosier DR's were definitely the most unstable once around 170mph upwards

In previous years I'd used MT DR's and 555R's at speed, all approx same size again and they were stable even at 190mph and even when pressures were probably lower than they should be.


Any idea how the M&H drag radials compare to the others ? I did email them, and they simply replied they dont comment on other tyres, the M&H are the best in the world.

I'm sure all sellers would say theirs are the best too.

 

I agree the et street/et drag suck donkey for traction and for sure stability on the street.

Don't trust them at all, made my butt pucker every time. And couldn't get near the time out of them

Never tried an MH but also hear good things, don't know if I could go away from the my radial for how well they work

Here is on 26x10 et drag.... Barely can get even to 130 before I have to lift or die. the last hit I actually made it to 130 and it was a 4.6 60-130



And here is on a 275/50-15 radial. It looks slower it is so drama free

 

Sorry for hijack lol

 

Don't worry about it. Exactly what tires are you running?

 

The 275/50-15 regular et street radial.

The 50 is the 26" … the 60 is the 28"

The ones that look like this



What u have pictured is the pro tire. Never tried one. They will be softer, don't know if this is good, as the et drags are really soft and they tear up on the asphalt and I think that is why they can't stay with the et radial for me. Where the radial tire surface doesn't get its **** kicked instantly/tore up when it starts spinning a bit under power from being so soft

 

Yeah that's what I figured. We will see what happens. The tires are a radial so hopefully they carry some of the characteristics.

 

 

I'm going with the pro on my next setup. Don't worry you'll be ok
