Mojave 1.5 Magnum Mile - ZR-1 Net Registry Forums

PhillipsLT5 · 05-30-2012

I am going to run this, this weekend
Any tips?
I have run several 1 mile shootouts before but now I will need to shift into 6the for 1.5 miles, I think it may slow down in 6th?
My car has 422 RWHP, 4.10 gears, elevation is aprox 2700, high temp will be 90, wind 15 to 20(hopefully tail wind)
My car ran the mile at 169.7, close to 7K in 5th
My car ran the 1/4 mile at 118, close to 7K in 4th
Dyno shows no more power gain after 7K
So I am pulling 5th from 1/4 mile all the way to 1 mile, fun ride
My car is tuned for 91 octane as that is all we can get out west, but race fuel will be available

I would try to find a 3.42 center section/batwing to swap in there

Sounds exciting. I'll admit that I juust don't have the guts to do it.

When Rick Mueller had my 91, he did the Texas Mile with a speed of 170.281. He gave me the certificate with the car. Kinda neat.

Good luck and be safe!!!

Hi Phillip!
You'll have enough runs, run it both ways and see.
Topped out in 5th, and shifting into 6th. Let us know.
I'm jealous, mine is still up on jack stands, and not smogged
yet. I'll miss this MM. Be safe and good luck to you and Jr!

no time for rear end swap, 170 is real strong for a mile
new ZO6's doing 172/173, new ZR1's doing 175/176

I can not stay too long, maybe 10 sec at 6K or more due to water pump cavitation

You need to do a search on my name and read the information on the water flow and thermostat. If you run the car over 5200 rpm your system starts routing the water around the radiator straight to the motor, the heat skyrockets because of this not water pump cavation. If you want to run these events I recommend an aftermarket high flow radiator and cut the thermostat main spring.

I have a stock thermostat, fluidyne radiator, will not get to 5200 in 6th, but I am there for sure climbing in 5th, wiil the temp guage rise or oil temp rise or both rise?

Hey Phillip
I say no overheating: You will only be at the higher
RPM's for a relatively short period of time compared to
sustained high RPM's when going around a track.
I would be more concerned with ballooning (is that a word?) the
radiator at high pressures/RPM's but I think your/our
systems can handle it.
And remember, its only $$$$!
