Stick racers.......step in please.
This question is geared toward , but not limited to , 9 second or quicker stick cars.
What was the single most contributing factor in getting you in the 1.20s......... Help a brother out please.....:D uh , that would be 60fts LOL |
Re: Stick racers.......step in please.
Figuring your 4 link is close, the thing that took us from 1.33 to 1.29 in SS\CS was shock settings both front, and rear, and limiting front end travel. Way more in the clutch also, but we never figured it out.

Re: Stick racers.......step in please.
In order of importance: 1) Clutch, 2) Suspension settings - IC manipulation, 3) Shocks, 4) Weight adjustment and placement, 5) Tires (considering you are not doing something stupid now)

Re: Stick racers.......step in please.
Where are you at now, and where do you want to be, and with what combination. Very vauge question. My bracket car is barely in the 9`s (9.972 best), and barely in the 1.2s (1.295 best), and also has ladder bars, with everything ahead of the roll bar main hoop stock. I`m guessing that you are looking deeper in the 1.2sand 9second ETs considerably deeper?

I've been thinking the opposite of what I used to on on rear shocks , meaning I used to like the bump valving stiff to help the car pitch rotate but anymore I'm going softer........and want to try much softer...........to get the car to "squat" and see how this effects the 60s.........definately agree on clutch but I havent figured out the balance between low base and c'weight yet.........I'm also clutch assisted. |

Re: Stick racers.......step in please.
How big of a tire are you running. I can tell you this much about my car, if it hooks , it will run slow, but get a good reation time. If it spins it will pick up 2 to 3 tenths. I only run a pro tree. .4. I set it up to hook, at least I try to. This past weekend, I slipped the clutch at the start, and I thought it slipped the tire then hooked. It was slipping the clutch. If I want to run fast bring up the r's on the starting line take some weight out of the back, slip.the tire some, and it will pick up a bunch. Just have to drive.to keep it in the groove. Lots of fun to drive.it this way. Lenco, with auto shifter.

That and softer rear shock settings maybe? |
Re: Stick racers.......step in please.
Go to a track that has some bite, Silver Dollar on a test & tune or weekly race does not have it. The wind blows a lot of sand on track, on Friday nights we blow the tires off in 4th gear. Commerce is not a lot better on a normal week.

Re: Stick racers.......step in please.
I leave at 5700 right now, and we will move that around a little to get the 60 FOOT , where they need to be, so that the package will be close to the 9.9. 7000 sounds like you at the top of what you can get. I really don't believe that you will get a whole lot more, by bringing it out at 8. Are you hooking or spinning, are you carrying the front out? I would step back from the car and try to find a little more power. Slipping the clutch is ok, but I feel it is a slippery slope, to get it exactly the way you want. I would not push your package too much, just race it and enjoy it, especially if it will be consistent and RELIABLE. Man, you must be buzzing that thing at the finish line with a 5.86. Are you in high gear at the 330 ft mark? I had 5.43 gear and it ran good, but I am at 4.86 now, and it is almost too much. My cube is 352, 5 speed and I am in high gear before the eight mile, I like to spred the gear changes out as far as I can

I need the 1.29 or better 60 fts and I will work on it til I achieve it:D Be it thru shocks , IC , pinion angle , clutch......whatever. |
Re: Stick racers.......step in please.
Joe, your car is fast enough to turn a 1.35 into a 1.26, 1.27 60' easy. We ran high 9.60's, low 9.70's and ran several 1.28, and 1.29 60's We did better with the shocks set stiff in the rear, and front, and the limiters tied down to 1" travel. Same basic tire you're running, but a 6.20 gear, 3.39 low. Also a soft loc clutch. Your ladder bar set up is still very capable of 1.20's. And we are completely lost in the bell housing.

Anyway , please show me how dumb I am and come fix it..........I'm gettin old and tired , but still willing LOL BTW how much base did you run and are you clutch assisted? |
Re: Stick racers.......step in please.
Joe, I'm the wrong guy to ask on clutches, chassis, etc. I'm barely smart on engines, but I will tell you what little I know. Yes, we were truly clutch assisted, clutching every gear. And sir, I made a mistake with the clutch deal. We were running the soft loc in the dart buick, which was 100 HP better then the iron head 291. it went 1.26 in 60. The runs we ran high 9's and 60 footed high 120's we were running a ram street strip rag, 30# steel fly wheel, and 1800# base. On the dart buick we ran sintered iron, aluminum 18# fly wheel, and i think 350 base. We ran better with the heavy pressure plate and fly wheel on the 630 HP motor, and ran better on the 720HP motor with the lite stuff. I know other people all run better with the lite stuff, but we never quite figured it out. And yes we go through the lights at above 10,000 in the 1\4. We also ran better leaving at 8,800 then we did leaving at 9,700. There's way smarter guys on here to help you with your 60 ft. then me.

Re: Stick racers.......step in please.
If it spins it will Pick up 2 or 3 TENTHS faster ET?
|
Re: Stick racers.......step in please.
Yeah GTX John, you heard me right, it will pick up 2 to 3 tenths if it does not dead hook. This is a Super gas car, if I feel it spin the tires, I know I am going to be way fast, and have to pedal it at the big end. I have attempted to run hi 8's with it and it has to spin the tire, to even get close. Do you know any stock stick cars that dead hook and run.fast? I think even pro stock like to spin the tire some. Auto cars to me like to dead hook. Yeah it pulls the motor down on the launch, but it moves.

Re: Stick racers.......step in please.
In a stick car you have to spin the rear tire 1 to 3 revolutions on the launch to go faster. if you are dead hooking it will just suck the wind out of the motor and it will try to play catch up the rest of the way and be slower

Re: Stick racers.......step in please.
I know that sounds weird to the auto trans guys but yes, you've got to spin the tires a little to get a good run. Obviously, the trick (if you want to win rounds) is to get it to spin the same amount each time.
Regarding starting time RPM, the best 60' that I ever had was a run where the two step malfunctioned. I normally leave at 8600, on that run the needle was off the end of the tach but boy, did it leave! If you want to 60', be brave and don't look at the tach. Obviously there is more to it than that but I don't think you can leave at 5000 and expect much in the way of 60' times. Jim Caughlin SS 6019 |

Re: Stick racers.......step in please.
very informative lessons here.
When I ran my chevelle as a stick I always tried to come out at a lower rpm like 350, car never worked as it was just bogging along. no torque multiplycation like the auto in the car now. I always tried to dead hook it and broke first gear twice lugging it in the torque band fighting for traction. autos have torque multiplycation and get up on the tire easier if I'm explaining/understanding right. sticks need whell speed to get the car going and get it from specific amounts of tire slip.
