Thanks Crusher. Nice try, but I'll still just be getting the front rotors.
Don't need much for back brakes when you are standing it on it's nose to slow down when the radar detector goes off!!

All I know is that the HP numbers that they get at RMCR have been duplicated
(within 1%) on a Dynojet Dyno in Texas when they take their car to the
Texas Mile. So it must be very accurate.

Ted, If you want to pay for it, find me a dyno around Yuma, AZ and I'll check it again at
120 ft. above sea level. I'm heading there on Tuesday and I'll be there for three weeks.

This is a good site for DA so you can find what you lose at Altitude and Barometric pressure, Humidity and Temperature,

Don't need a web site to tell us Colorado owners what we lose due to altitude. You just have to race at Bandimere with DA's in the 9000 to 10,000 ft range and you know right away. A car that runs low 12's at sea level
runs nearly 14 sec 1/4 mile times. That's why we will never make the fast list.

I know that, It was for all the guys on the forum too, Guys don't know, I in the summer have a DA of 5200'-6500" and i am at 600' above sea level.

Bump for Further Discussion.

Congrats on this install and thanks Don for some real usefull info. This is the best Vortech install I have seen, great details: the use of the screen and the cutout for the intake.

I hate to thread jack but is there something on the market that would be easy to use to make adjustments for altitude without a lap top? I know you have to deal with other factors but at least to get your air/fuel and boost adjustments. I am at 2600ft and hate to have a gas hog when I go to the shore. Or maybe that is not enough altitude difference to worry about?

Your only talking about a 8% loss in power compared to sea level, and the computer is self compensating for all conditions, so No Worries, When we Choose a Pulley for the car we can add an extra LB of boost.

I'm assuming this car made about 720hp at the crank?
Awesome build. That car must really move.

Here's the speed I did on my way to AZ. This was somewhere in the desert at 6400 ft altitude and the outside air temp was at 20 degrees and the tires were fairly cool. I could see for 10 miles ahead of me,
not a car in sight, at about 6:30 a.m. I was in 5th gear at about
6300 rpm's when I hit this speed. The car handled perfectly, didn't feel light,
just hugged the road and performed beautifully.

It's alot different highways out west. There are stretches of interstate
where you can actually see the highway where you will be at in another 30 or
more minutes of driving at 75 mph. And not a turn in sight, straight as an arrow. And not another car in sight. Back in your part of the country there some roads that are capable of those speeds, but the traffic
volume won't let you even come close. We didn't even have a speed limit in Montana until a few years ago. As long as your car was built for it and had good speed rated tires the highway patrol would let you run wide open.
Of course it also helped that I was dating a highway Patrol officer at the time!!

I'll definately have to head out that way if I ever get my sc. You've got an excellent ride there. I can tell how proud you are....

BTW - hope the relationship ended well....

Yep, still good friends. And now my sister is marrying a Montana Highway Patrol officer. I hope she treats him good!
