At the risk of sounding stupid, I have a question. I've been reading anything I can get my hands on about rotarys. In doing so, I have noticed many cars running surge tanks. Even rotarys running on gas, not just alcohol. Now, I know on a large alcohol motor with huge fuel lines, a surge tank becomes needed. But why am I seeing surge tanks on rotaries that are running on gas?

An attempt to prevent fuel starvation from the pickup in the main tank.

No fuel/not enough fuel under boost = POP!

Are you implying that its just a factor of over engineering? Ive only noticed this trend when it concerns a rotary power fuel injected power plant. Any other FI engine fails to have the surge tank (speaking in terms of cars running 9's or slower). This is what struck my curiosity.

i think its just cause the fd tank pickup stinks. when you get the tank low on gas you can starve it for fuel on the stock tires

Check the link out. Click next two pics to see how I ran my set up. The reason why I went this route was the 1st gen carb fuel tank had 3/8 fuel line/hose to the motor. EFI external pumps need at least 7/16 fuel hose to the pump. This was easier for me and also put the two pump closer to the injectors. SDS (sdsefi.com) has a good write up on how to and why for converting carb cars to efi. chuck |
