I'm a new P1800E 1972 owner and am curious about your progress (well, I'm supposed to go pick up the vehicle tomorrow afternoon). Your vehicle sounds like it was a lot like the future donor of mine is now.
My true reason aside from knowing more about yours, is that on my 72', the previous owner switched TO carburator, and got rid of fuel injection.
I didn't know why, nor did the current owner, know why the original owner switched but it may have something to do with this information I found in this link:
VOLVO Parts and Accessoires. VOLVO Parts for VOLVO repair and VOLVO Performance upgrade! www.VLVworld.com sells New and Used VOLVO parts for 240, 850, 740, 760, 940, S70, V70, S40, V40, S80, 140, 122, 164 and More
If you scroll down to the 1800D 1970's section specifically:
engine is all the same as the B20E
engine, but stricter pollution regulation forced compression ratio reduction to 8.7 to 1 on the B20F
. The power went down to 107HP. All cars sold in North America have the B20F
low compression engine..."
So, I'm guessing they tried to improve the hp by putting carb's? Not exactly sure.
I also read somewhere that you can change the gasket thickness to increase the compression ration, therefore giving you that HP back. I could be wrong.
I'm sure this is common knowledge to all you P1800 enthusiasts, but I'm just a couple weeks into it.
Let me know what the masses think... and what they've done to get serious HP gains.
Thanks & oh... I'm a new member here. Sorry to jump on this post for my 1st but, I like to have something to input rather than "Hi... I'm from Tallahassee and..." haha...
