500HP quarter mile times

[Meanmyz]

Hi guys,

I am "on deck" for a Haibeck 510/350 package! I was just wondering, "what are the avg quarter mile times for 500 hp cars, for those of you who are running a similar package/hp/setup"??

No need to get too technical. I don't plan on changing the rear gears. At least not right away.

So if really good stock times are: 12.8 - 13.1 seconds @ 110 - 112mph, then typical 500hp LT5 times would be...?

The thing is...I probably already have a pretty good idea, but like everything LT5 or ZR-1, I like to read it over and over again, or let "soak in"

Don't worry about e.t. its just a measure of how badly you want to break parts If I were you make a few runs at a local track or GTECH/iphone app your car and you can expect about 8-9 mph on top of that ideally.

What's his 500 package consist of?

12-12.2 or so on street tires....119/120 or so.

Traction is hard to come by and you have to lower your launch RPM....

[LGAFF]

To put it in perspective....when I got my stock 90, the first run I launched at 1500 went 13.3 at 109. Raised the launch to 3.2K I went 12.88 @112.68MPH....

With the 500 package you lose the ability to launch at 3K+.....on street tires...

I did watch the videos from the thread about the FBI "doing it again", and I was surprised how those guys seemed to launch at such low rpm!

Low restriction exhaust, headers, tune, lightweight flywheel, porting of the plenum, injector housings, heads, ... Stock cams...All the tried and true stuff, but with the special touches unique to the builder.

12.5 @ 118, elevation 1K, 60ft = 2.1, street tires, 410 rwhp
60 ft means everything, every 1/10 = 1.5 10th at 1/4

A lot would depend on your tires. With street tires you should be able to cut low twelves easily, possibly high elevens.
My car has most of the equipment Mark recommends, but with a stock engine, see below. With practice, all that stuff will cut a full second off your times.
Then if Mark does the top-end you get about another 1/2 second.
Then if you do the myriad tweaks Pete is famous for, you're banging on the tens.

Don't worry about e.t.?..........Huh?

Low E.T. means you got there first, you win. There is no bigger thrill at the drag strip than to beat a car that cuts a better trap speed. That means you won the race with less power.
