Hi, I am in the process of refreshing a 914-6 GT tribute car that was built for PCA solo events in CA and has been mostly in storage for several years. The engine is a 2.4 that was built by GD racing in San Bruno. The suspension and brakes are 3.2 Carerra. I pulled the calipers and they are at PMB. New soft lines are going in. I was somewhat surprised to find the stock 914 brake pressure regulator still in place. There is no after market proportioning valve.
The car will be used a few times a year for vintage wheel to wheel and then some PCA DE events. I have several years of experience racing vintage FV. As I got older and saw several buddies get involved in some nasty open wheel tire to tire incidents I decided I wanted fenders and more metal around me. I am not the most aggressive driver in the world and this car will remain street legal. I also want it to remain as period correct as I can get. I don't want to go down the rabbit hole of cutting a ton of metal out of the car, etc. Should I pull the regulator and put a T in and proportioning valve in the cockpit? Should I leave as is and see how it performs? If I leave it I will send to PMB to have them rebuild it. Cheers, Jerry |

Well, I take no credit for the build. I wish I was close enough to check yours out! It was done by a Porsche tech in the Bay area many years back. I'm just trying to get it back on the track. I got the brake calipers back from PMB and am hanging those with new soft lines. A new MC will be installed. I also have a fuel cell from Patrick Motorsports ready to install. The Weber 40's were in bad enough shape that they went to a local mechanic after I failed to get a plug and jet holder out due to them being so stuck in the carb body. The hope is to get this ready for an event in late April or at least early June. |
