Questions re: Weber 44 IDF carbs:
1. Is anyone running these on a stock engine, and if so, how do they perform? National Carburetors kit for stock engines is 34 ICT's, lightly modified 40 IDF's, and only 44's on heavily modified engines. 2. What problems do you introduce using 44's? other than dumping too much fuel in the engine...... 3. Venturi's are 45mm, someone pointed out that one should use 40mm venturi's - is that with a stock engine? 4. Anyone run 44's and then convert back to EFI? How did that go? Labor cost? TIA, GN |

Got a call from my good friend in whose barn the 914 was parked for about 12 years. I brought him up to speed on how things are going with the car, and the whole issue of the carbs.
He re-affirmed to me today what he had told me earlier: he had been riding in the car through that day with the PO (also a good friend of his) and he said he was really impressed with how strong the engine was for a 2 liter. He affirmed again how well it ran. SO, I am going to initially install the 44 IDF Weber's with the 44mm venturi's. I gotta find out what he is talking about. And if the Weber expert at Pierce Manifolds in CA was correct about no mid-range torque. Who knows? If it runs great mid-range, I just may return the 32mm venturi's. On a related issue, Ken in Cinci (bigkensteele) sent me a pic of the D-Jet system and I was blown away at the tiny throat on the throttle body. Looked like 28mm. How can that thing breathe? And the air intake nozzle is even smaller! Heck, the throat on the Amal carb on my '71 Triumph Trophy 500 is 26mm! So anyone tell me the diameter of the throttle body throat on the D-Jet? TIA, GN |
