Super gas/comp/Street forums?

Hello All.
It would be nice to get more guys/gals talking on here or other forums.
I guess it is all top secret, and nobody wants to give in and tell all.

But then again, if you start something most guys will chim in, right or wrong they will chim in.

As in a Field of Dreams (I think that's the right name of the movie)

Cal, there is some truth to that and I also think that the only forums that gets regular traffic here is the stock/stock forums and the classified forums. That said, I'm far from being the expert on throttle stop racing but if you think I can help, just ask.

Okay, I'll start. I like to run a lower cruise RPM for a shorter time. The thinking is I can get into high gear sooner for longer and make more MPH. Saw a couple of MPH.

So getting on the cruise quicker will help MPH.
But will it effect consistency or 60 ft?

No, we go on cruise at the same time, just at a lower RPM. Because we run a lower RPM we don't have to be on the stop as long. Like anything else it depends on what the car likes. We've run it on 540 and 565 engines. I'm not sure it would work well on a small block.

I wonder about this also. If we have a car that runs SG, 9.90 @ 160ish. If the stop stall is
4200 for 3.5 seconds. How fast is the car at 4200 for the 3.5 seconds? Lets just say it's
130 mph and then gets to 160 at the finish. If the same car is 4000 rpm for 2.5 seconds. Is that car now running 125 mph. Does it get to 165? The car is at a slower speed and has more time to accelerate, but can it over come the lower rpm while on the stop to run faster at the stripe? Or, is it better to be at a faster mph on the stop and not have as much mph to gain? I have heard many discussions about this but I'm still not sure which one is better?

It doesn't really impact what you are trying to say, but those speeds on the stop seem really really crazy to me. 130 mph while coasting on the throttle stop? Not unless you turned the stop on at the 1/8 mile!

If two identical cars have the same cruise RPM, the one that goes on the stop quicker should have more top end MPH.

If two identical cars go on the stop at the exact same time, the one with the lower cruise RPM should have more top end MPH.

My personal guidelines are:

1. The 'stop on' time should be just high enough for the car to cut a light.

2. The cruise RPM should be set so that the car can at least clear the 60' beam while on the stop every pass in any weather conditions.

There will be other things to consider in each case. Some cars may need to be WOT a little longer at the start to work the chassis properly. Some cars may come off the stop cleaner with a little higher 'stop on' RPM than absolutely necessary.

I run oddball combinations in both of my cars, so I can't always use these principles but I use one of them in each car.
