Honestly, I don’t know the answer to that. The place that I got my harness and computer from also supplied the pedal. I opted for the corvette pedal specifically because of the metal arm. I don’t know if they included a different connector or if that’s a standard GM item.
I have a Gen V L83 in mine, but used a 09-13 corvette pedal (GM 19417903). I cut off the "pedal" portion and welded on the lower section of my stock 80 pedal so it at least looks proper.
Thank you! I have an L83 + 6L80 in mine and am just at the point of needing to connect things. The sensor is mounted but I need to carry on with the wiring. I spoke with Dakota Digital and they were hesitant to say that it would power incandescent bulbs. Thanks for confirming!
If your mounting studs measure 3-3/8", check into a 1970 corvette master cylinder for a MANUAL brake application. It'll have a 1" bore and should have the 3-3/8" mounting dimension. Dorman M36367 or similar.
One thing that may help, is to measure the width of the MC mounting studs. It’s likely either 3-1/4” on centers, or 3-3/8”.
The tandom willwood master cylinders have somewhat elongated mounting holes and should accommodate both. You may still need to make a custom length insert/slug/bullet...
@jjdeneen918 , I think that might be hard to track down via images. I believe that Delphi manufactures these for GM, Dodge, Ford, and others. I’m guessing there are minor variations like the spread of the MC mounting studs, fittings, etc.
You’re correct. Hydroboost (typically) puts out more force than a vacuum booster.
I’m still puzzled by your problem though. The Hydroboost (even with a 1-1/6 or 1-1/8” mc) likely generates as much line pressure as a vacuum booster with 1” mc. Very strange.
1" bore vs 1-1/16" bore = ~12% difference (closer to 13 actually)
1-1/16" bore vs 1-1/8" bore is also ~12% difference
1" bore vs 1-1/8" bore = about 26% difference
The reason for a larger bore size is if you need more volume for your calipers. Ford super duty's for example have up to a 1-1/2"...
