Re:turbos and carburators
I wouldn't say that it's better or your going to ge tmore power out of it but it is so ez to tune. the main reason auto companys use injection is foe emissions.

Re:turbos and carburators
actually EFI really got going once auto makers realized engine longevity improved about 300%.

What about aviation grade fuels. standard is low lead 110 octane. so being a bit lean or having a hair to much timing isnt such a big deal. lets talk about compression ratio on planes. 9.0:1 at 10,000 feet is like 6:1 at sea level. You really want to go down this road go ahead. there is no good way to turbo a carb. sure its been done but its not the best way to fuel the engine. nor is it such a great way to manage spark. If carbs were so great dont you think honda would still be using them or GM or Ford or Nissan or Toyota in Fact harelys now have EFI and to make things even more interesting so do most new planes. No reason to stick with antiqauted technology from 1910. that's a lot easier for someone to read and understand than just simply stating that you feel it's like playing catch with a hand grenade. i never said it was the best way to go about doing things, i just said it was possible and much easier compared to computer controlled fuel injection, especially OBD2, which i'm currently dealing with right now. i'm not going to run out and carbeurate my every day car, but if i wanted to build something for fun at an absolute cheap budget i'd go with a big edlebrock or holley carbeurator on the intake side of the turbine, it's cheap, not very efficient, but it will produce a lot of power. anyhow, i think the main question has been answered, i want to see banshee pics. i'll post one here of my roomates banshee. it's an old pic, since then he's put on toomey t6's, cut the front fenders off, put on extended front A arms from ALBA i think, and a bunch of other junk. it's a pretty fast bike. my other roomates quad is an 87 that we just restored, it's still having issues, i'll get pics of it up some time. |

Re:turbos and carburators
for what youd spend on a carb i could show you how to do it with factory GM hardware for about $50 minus fuel injectors.

Re:turbos and carburators
I'd be intersted in that if I understood that sort of thing. I have heard of this before, but I'm not exactly literate when it comes to programing ECU/ECM's. :-[

Sean88:
I think I saw your setup (non i/c-ed accord, gm comp...) a while back when you joined here... Do you have any details on this setup? I read your website a while back and it didn't give tooo much info (or maybe it was your posts)... But I'm still curious as to the details / inner workings / complexity of this setup. Thanks! |

Re:turbos and carburators
IMO, carbs are ass to use with turbos. They rely on low-pressure fuel pumps so a small pressure change in the fuel relative to the boost pressure can make big changes so you need a good pressure regulator. Then there are the other carb-related issues.
Converting to fuel injection is simple enough, why bother with carbs these days? |
Re:turbos and carburators
yeah, you need a special regulator to hold the carb's fuel pressure at, i beleve, 6lbs above boost. Carbs usually use 6lbs fuel pressure, so if your boosting 10lbs, your fpr would have to hold 16lbs fp to make the carb function like it does normally... now that i think about this, it's not all too special... a 1:1 regulator.. ha!
