To be honest, I didn’t really get enough data to make a decision. If anything they might need a stiffer compression, I’m also thinking stiffer torsion bars in the front might keep it from dipping too much under hard breaking.

@johnfiore91 2 ай бұрын
These types of events are sanctioned by the Pa Hillclimb Association but you’re correct, they are not considered hillclimbs, these track based events are called track sprints. They are run the same way as a hillclimb, solo timed runs. There are two types of hillclimb racing, this type is more road racing based and is also the oldest form of motor racing in the world, the other is straight up a dirt hill that’s more like a cliff. Classes are determined by several factors like engine displacement, type of chassis/car, etc. (a lot of that I still am learning) The goal is to have the fastest time for both your class and overall.

This will be random and rambling. . Real Watts links like the hillclimb (hc from now on) can’t tolerate much variation from vertical when viewed from the side and through the bell crank. Also, the link arms must be straight and inline with the heim joints on the bell crank. Any offset will lead to binding and breakage somewhere.
@truthboomertruthbomber5125 4 ай бұрын
All the engine torque multiplied by the trans and final drive gearing is being fed into the frame by your lower arm and it’s mounts. There is no way this concept can do the job being asked of it. The heims are way too close together and too close to the centerline of the axle. The forces being fed into the arm are immense. There is a huge bending moment being applied to the arm. When those huge slicks bite and the pinion gear is “climbing” ( QC, I know ) the ring gear the upward force is hammering the lower arm and its mounting brackets and the center section of the QC.
@truthboomertruthbomber5125 4 ай бұрын
The rear arm’s geometry cannot meet any of the requirements needed for a successful Watts linkage installation. The the bell crank’s path is an arc not the vertical flat plane required. Also the upper heim moves through a different arc than the lower. I’m talking about side view here. This doesn’t address the issues that exist in the upper and lower links as they articulate due to suspension travel.
@truthboomertruthbomber5125 4 ай бұрын
Now we come to the interaction between the outboard axle location design which causes the axle to travel through a mostly flat vertical plane and the center arm which forces the center section to travel in an exaggerated arc.
@truthboomertruthbomber5125 4 ай бұрын
This is all meant as an educational constructive critique. You are in a battle between the design element necessities and your mental concept of staying true to “it’s a real sprint car” . . The DEN requires the rearend housing to feed longitudinal and lateral tire forces into the frame with no binding of the locating links or the driveshaft. It must do this while traveling in the vertical plane due to bumps and driver inputs via throttle, brake pedal and steering wheel. There is also the winning credo of KISS. That’s out the door at the moment. . Rearend location is going to make or break this project. Right now cosmetic considerations are forcing impossible constraints on engineering.

@truthboomertruthbomber5125 4 ай бұрын
Have you cycled the rear suspension through it’s full travel? Short driveshafts start to bind up pretty quickly. You likely have way too much suspension travel for the pavement. Also more steering lock than you need. The steering ratio may be too fast making the car difficult to drive smoothly and accurately. Ditch the torsion bars. Coil overs will be much easier and cheaper to dial in. You could use one of the torsion tubes to house anti sway bars. A sequential transaxle with paddle shifters would eliminate the shifting issues and really help the performance by giving you 5 speeds. The required IRS rear suspension would of course be a complication but no worse than your current setup that likely has a lot of bind and who knows what sort of instant center, roll center, etc issues that are present. One last thought, you may be killing the clutch with all the slipping driving the car around the pits.

@@johnfiore91 Carroll Smith wrote several books back in the 70s and 80s that were recommended to all beginning SCCA racers. "Prepare to Win" and "Tune to win" were his originals. One of the best ideas was what he called "paper dolls". You measure all of the suspension components and pick up points and then cut out posterboard facsimiles and draw your suspension pickup points on an adequately sized flat surface and then you put the posterboard trailing arms, etc on the flat surface and work the parts through their travel. Nowadays you would use CAD programs to do the same thing.

Agreed with tailshaft. My old Supermodified [1968 forerunner to a Sprintcar] has this issue and is possibly longer @ 92". You need the suspension to go up and down, through a very small arc. I have clearanced both front and rear yokes to gain angle. You will only require max 6" of travel, 5" will do ok. 3.5 down and 1.5" up from ride height. And yes I once hillclimbed it,,,, rear brakes only, chassis set remotely square and even dia tyres. I just needed 3 hands!,, one to steer, one to change gear and one for the brake. It now has a hand clutch which will make it harder. Coilovers would be simpler and easier to 'tune' and using one torsion bar per end could make a good sway bar. I doubt you would need one front but a softer front bar in the rear would be ok rear,, make it adjustable. That is the way I set up my road race tintops for hillclimbs

IMO you need to think about you first foray at Pikes Peak in 2026. You need to spend 2025 making your car 100% reliable and nearly maintenance free. You should still go to PP next year but as a spectator. Spend a lot of time in the pits talking to old hands. See what they are doing. Solutions they are implementing. The old saying is “learn from the mistakes of others “ but the more important motto should be “learn from the successes of others “. Preferably really smart “others”.

My best friend was on the tour for 2 of the 3 years. For comparison, his car is 2500lbs while mine is about 1900lbs. I like his car and what he and Roger Johnson accomplished but it’s not a sprint car (even though he proclaimed it was lol). My car’s chassis ran with the World of Outlaws Sprint Car Series in 2017. I know some will try to argue that but midgets and silver crown cars are not sprint cars.
