Super gas/comp/Street forums?
 

Are there any more forums out there for throttlestop racing? This appears to be more of a super stock/stock forum

Re: Super gas/comp/Street forums?
 

I guess we just don't talk much....

Re: Super gas/comp/Street forums?
 

This was the place at one time tho.

Re: Super gas/comp/Street forums?
 

We need to contribute questions and ideas and bring it back.

Re: Super gas/comp/Street forums?
 

Super Street is a very competitive class and a lot of racers won't just give up hard won secrets. I get that but, other than a couple of things there isn't much I won't share with my fellow racers.


My feeling is that now matter how consistent one's ride is, if the racer can't let go of the button at the right time and drive the stripe he's dead meat anyway. Unfortunately, more times than not I'm in that group.


I don't think the combination I run is unique, just different. I'm happy to share just what it is.

Re: 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.

Re: Super gas/comp/Street forums?
 

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.

Re: Super gas/comp/Street forums?
 

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.

Re: Super gas/comp/Street forums?
 

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

Re: Super gas/comp/Street forums?
 

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.

Re: Super gas/comp/Street forums?
 

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?

Re: Super gas/comp/Street forums?
 

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.

Re: Super gas/comp/Street forums?
 

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!

Re: Super gas/comp/Street forums?
 

That had me confused as well. I don't remember exactly, but I believe my datalogger showed MPH on the stop at just over 60mph. And my cruise RPM is on the high side.

Re: Super gas/comp/Street forums?
 

my car with a 4.88 and 32 inch tire shows about82 mph at 4200. drop to a 4.30 would be about 93 doing the basic rpm tire diameter gear ratio calculations. ofcourse thats with no convertor slippage so its actually less

Re: Super gas/comp/Street forums?
 

My completely uneducated guess would have been 40-60 mph for most cars.

Re: Super gas/comp/Street forums?
 

Mine is probably slower than that since my cruise is 3,600 rpm's

Re: Super gas/comp/Street forums?
 

I just picked a mph for my discussion. I have no idea what the stop mph is. Those numbers are probably more indicative of the 1/8 mile mph. Just saying that if you start at a slower mph but have a longer time to get to the finish, versus a higher mph but shorter time to get to the finish... Will it change the finish mph much?

Re: Super gas/comp/Street forums?
 

Of course it will change it. More time WOT will produce more MPH unless your engine has its tongue hanging out by the finish line. The definition of "much" is up for debate. Will it be enough to change the appearance of the race for you and your opponent? Probably not unless your timer or cruise RPM change is dramatic.

My dragster is mechanically injected, so I go on the stop at 0.100 and shut it down to a dead idle. My cruising speed is almost a stop. I also come off the stop in Low gear. I've never run this combination wide open to the 1/4 but I only lose 2-3 MPH at the 1/8 mile when running 8.90 on the stop as compared to a wide open pass. 6.19 @ 145.86 compared to 4.69 @ 148.14.

I would hazard a guess that cars running a more traditional cruise RPM and coming off the stop in High gear are down 10+ MPH at the 1/8 compared to a WOT run.

Re: Super gas/comp/Street forums?
 

I do know if you are low on power dropping that cruise rpm gets unpredictable. And if you make good power getting it too high puts too many numbers in the timer. It’s a test and tune fine tuning point til you find what works on your car. I’ve been on at .001 with a Maxspeed, on at .10 same carb...you just have to have enough power to do it that soon or it will know the breath out of it and you’ll get a dip. I had a big motor combo that liked .001 and shift at .020.at 4300 and it worked well. Tried it with a smaller motor and it was a no go

Re: Super gas/comp/Street forums?
 

^^^^ This
Every engine/combo is different. The key? Test, Test, and Test some more. The combo will show you what it likes, not the other way around...

Re: Super gas/comp/Street forums?
 

4400 on launch, .050 on stop 2300 rpm, off stop 2.75, 10.90@147 and change at the stripe works for me

Re: Super gas/comp/Street forums?
 

Lenny5160,
When running 9.90 I go on the stop at 0.001 and coast at 4150. I come off the stop in high gear. My 1/8 mile is 7.02 @ 131.83 compared to 1/8 mile WOT 4.66 @ 150.00


I lose 18-19 mph.

Re: Super gas/comp/Street forums?
 

You're about the highest MPH S/G guy that I know of. Probably coming off the stop around the 330 cone.

Can a double 0 dead on 122 mph car beat a 150 mph car?

Re: Super gas/comp/Street forums?
 

119 Beat my butt more than once.

Re: Super gas/comp/Street forums?
 

I have a 57 chevy sbc mini blower I have been kicking the S/ST idea around. This would be just a fun car trying to run 10.80s flatout footbraking it. I'm usually red on a pro tree. I would give it a shot unless someone talks some sense into me. Has anyone ever won without all the electronics? Im sure there would be a train following me to the lanes.

Re: Super gas/comp/Street forums?
 

Yes a former IHRA world champion in the 1090 class used to add weight, very hard to beat.very slow car
another guy from Atco runs our .90 series sometimes and uses no electronics and is very good
If I had a roll bar in my street /strip car I would use that as a back up without thinking twice.
Give it a try you might get hooked I see you are from Pennsylvania come run one of our mid Atlantic .90 races, the tree is set at .500 not @ .470 it would be perfect to get some seat time

Re: Super gas/comp/Street forums?
 

How can you run a 9.90 class with no electronics?

Re: Super gas/comp/Street forums?
 

Go duckhunting and say a prayer

Re: Super gas/comp/Street forums?
 

Former World Champ in SG Ed DeSault does it regularly on the west coast.
He has started running mostly Nostalgia series on the west coast recently however, over the last several years he has competed in Division and National events and made many rounds with only a trans brake and a bolt adjustment on the throttle linkage.
9.90 in the 130 MPH range
Everyone to his own thing.

Re: Super gas/comp/Street forums?
 

The thing is without a transbrake, it would be tough on a .370 tree.....
I agree with the no t-stop, many ways to get to the # , being slow isn't a disadvantage!

That's awesome didn't know that
