Re: Ben Jammin's 1955 Chevy/GMC Project
 

yeah when i started thinking about it further about the way i discussed it i blew a couple of holes in the idea myself , rpm alone doesnt show true torque
you allso need trottleposition traveled distance per amount of time wish can be done by gps or by pulses for the speedo from the car itself gps would be most acurate as tires spin

the gps only way does make more sence it can calculate torque at the roadsurface from the total weight of the car and traveled distance per amount of time , there wouldnt be anything else needed and it would be exact as long as theres traction the accuracy would depent on the amount of calculations per time (one calculation over a 1/4 mile would give an avarage torque while one every tenth of a second would give a graph of the whole run)
the torque displayed would be the torque aplied to the road from the tires , spinning tires would lower the reading as the car travels less distance , it might make a nice tool for tuning a car for traction its more acurate then seat of the pants adding trottle position hunidity and tracktemperature to it could make an adjusted graph over a complete run (it can calculate the difference to wat it would be if temperature and humidity where optimal )

this stuff gives me a headacke but i know it can be done

Ok, I think I see where my confusion is coming from. When I said I wanted to install the x86 version of Android on my VM and then install Torque, I ment the Android application called 'Torque' not to try and measure torque! Sorry for that! The program 'Torque' can estimate HP with some other factors, but it is just an estimate. I don't think it estimates torque though and that isn't a number OBDII tracks either so there isn't a way to accurately get that number from the data available. I did read a few years back, I think it was in Hotrod Mag, that some guys was trying to build a sensor that was placed on the drive shaft and would provide a the main missing piece of data to accurately measure torque without a traditional dyno... don't know where that went though.

it should be possible to build a loadcel into the drive shaft the problem would be getting the info out of the spinning drive line and have the electronics stay alive in there too
Wat he could do is make the engine(plates) pivot on one side (the side the crank spins into ) and place the load cell on the opposed side between engine(plate) and frame , the engine will push down on it during the run (opposing against the drive line torque) and the weight can be calculated into torque you still measure as far as the tires will hold and it will prolly be a fat line from all the vibrations coming of the engine while its running but it would be similar to a rolling road dyno and gives more accurate data with the weight and drag of the car being pushed and all

the horsepower device you're talking about , i heared about a chart once that you could estimate horsepower against you 1/4 mile time (this amount of horsepower is needed to push a car that weight in that time ) it could be they just put the chart into the computer nowadays , heared about a stick on the window type computer that measures g force too

i think the person thats able to build something like the torquemeasusering device I'm talking about could make a bundle from it

Hey guys, I'm going to be out working in the shop all day today, I am going to be working on getting the frame coated and putting the rear suspension together, stop by if your bored!

I got quite a bit done the past two weekends. Most of that time I have been streaming my video for some family to see. I'll try to update on here before I do a lot of work so you can see what I'm doing it real time!

Started off by taking all the suspension off and flipping the frame to get underneath coated. The floor of the shop was nice and clean before I got started!

New leaf spring bushings and pins all the way around! Got all of them from my local parts store.

All grade 8 hardware by the pound from Tractor supply ( I would go broke if I couldn't get it from them!)

Ive got some shock mounting issues I have to iron out, but other than that all the suspension is done! I forgot to take pictures after the front end was on, but I'll post some later.

Looks great man. I checked out your streaming video a few days back. Kinda makes me want to put a web cam out there... I just don't want anyone to see how much sitting and "thinking" I do! (Or how often I have to re-do stuff!)

Ive got the rest of my shocks in place and a built a cab dolly so I can move it around while I work on it. I made the inside the same width as the frame and the supports the same dimensions as the stock cab mounts on the frame. I changed the design a little bit from my drawing because the supports were a bit overkill.

My measuring actually turned out right and the bolts lined up to mount the cab to the dolly. It rolls nice and smooth, I think I'll be glad I spent a little extra time to make it.

Sweet work on the dolly! I may have to make me one like that!!

Re: Ben Jammin's 1955 Chevy/GMC Project
 

Looking good. I'm not taking my cab off or I'd copy your dolly. I'm using the same p/s kit as you and haven't done anything with my left front shock mount yet. How did you mount yours? Are you moving your right front shock to match the left?

Re: Ben Jammin's 1955 Chevy/GMC Project
 

Russell,
I will post a picture on here this afternoon. The instructions for the P/S kit suggest a location for the shock mount. The location they suggest shortens the extended length of the shock by a good bit. In my situation, I have a drop axle that makes things more complicated. The instructions also suggest to use a Passenger (right) side lower shock mount bolted to the I-beam. For my particular application this interfered with the tie rod that I had to move due to my drop axle.

I used the original Drivers (left) shock mount and flipped it upside down and altered the shock mount bolt to make it work on the right side. Doing this additionally shortened the extended length of my shock. With all that said, I could not mount the upper mount (the one removed to install P/S gear) in the location suggested by the instructions because I would not have enough shock travel. SO, I measured how far forward the upper passenger shock mount was from the center line of the axle and used that measurement to install the mount on the drivers side. The extended length is still shorter on the drivers side than it is on the passenger side, but it appears to have enough travel.

I do not yet know if it interferes with any fenders or anything, but it seems to be sufficient for a shock mount. I am not changing the passenger side shock location. In many stock setups for various vehicles they actually having the shocks coming in from either side.

That is a lot of text, but I hope it helps. I will add some pictures this afternoon.

Re: Ben Jammin's 1955 Chevy/GMC Project
 

Sounds like we ran into the same issues. Getting the shock mount installed is one of my next chores so I'm interested in seeing your pics.

Re: Ben Jammin's 1955 Chevy/GMC Project
 

I had to trim the fram a little bit around where the original steering gear was and I used washers to make the mount level across the side of the frame. If I remember correctly the bottom bolt hole is already there, I just made it a little bit bigger.

As you can see on the bottom picture, I basically pointed the triangle made by the mount bolt holes toward the bottom shock mount. This is how the other shock is setup.

I started slicing and dicing on the cab yesterday. It made me nervous, but I had to start some time! I actually made and welded my first patch panel today, and I think it came out pretty good. I definately have a long way to go!
