Racepak for stick cars

Dirk Olson · 04-15-2011, 04:48 PM

Mark,

I actually had thought the same thing accept I bought a couple differant split collars and they are way to big, along with not having much room between the cluster and main shaft gearing. If you could point me towards where you got the split collar I can make the rest. This would GREATLY appreciated!

Dirk, I made my own collar. As you know all the commercial ones are way to big. The collar must be 2.375 o.d x 1.750 i.d x.375. with a small notch in the i.d so the oil relief hole in the counter shaft is not obscured.

I use 3 inputs , Engine Rpm, Input shaft/ Clutch Rpm & Driveshaft Rpm
Is the tire spinning or the clutch slipping while using one sensor for both.

Has anyone put this sensor in a Gforce G-101 4 speed? Is there a good way of doing it?

Mark, what racepak unit do you use?, and does anyone know if the correction can be put into the sportsman and the v300 ?

Thanks,Dave

Monty, by having the engine rpm and the input rpm, you see a true graph in every gear, all the time, another words you see proportionally how much the clutch is slipping. The driveshaft rpm increases continually and it is harder to see the true slipage. Comp and prostock cars have it easy putting the sensor right on the input because mainly they have more room to get the sensor in the bellhousing astheir bellhousings are much deeper than ours and have a different input setup.

All that being said, I am no expert on this data stuff as I don't have any in my cars yet, I just have an understanding of it some what.

Todd,

G-Force can supply a bearing retainer fitted with a bung that will accept the sensor. They can also supply the necessary sealed input bearing.

I have a input sensor on my jerico in my ss/i car that is exactly like the one Mark built for his. I did alot of research and no one makes a kit to do this, including jerico. There is no way we could see to mount it to read directly off the input shaft. My machinest made a slip collar with a magnet that installs on the cluster. We drilled and tapped a 1/2 hole in the case and used a 1/2 bolt with the center machined and tapped to accept the sensor. My trans. is a older bottom loader and was easy to set up with that bottom cover removed. I use a computech system and it will convert the main drive ratio to 1:1. I have a new jerico trans. that was just finished last week and they installed the collar and drilled the case for me. The new trans. does not have the bottom cover so need to install sensor and collar as the trans was being built. This has worked well and have seen a few others done the same way.

Lots of good feedback on the Jerico installation but I'm still wondering if anyone has put the magnetic collar on a G101 countershaft?
