Only a real kook would try to turbo a 914 with a pull through side draft carb! (IMG:style_emoticons/default/poke.gif) (IMG:style_emoticons/default/welder.gif)
Serial, a system like that works fine and doesn't run hot if set up right and not over-boosted or run lean. I definitely did not want to mess with ethanol injection and did not need it. I limited my boost to around 7 psi but cranked it up to 9 psi a few times. It was happier around 7. That was on the street on pump gas without additional cooler or oil cooler or anything else. Unless you switch to a different induction you can forget about inter-cooling. Your setup has fuel being mixed with the air and going into the turbo. that's already bad in that it can centrifuge out the fuel and cause puddling a little. It's manageable. but if you add an intercooler, you'll be giving the fuel an even better motivation to puddle and separate and pool, causing rich and lean spots which on a good/bad scale, are down near the bottom closer to bad. Run it a little rich on top end, manage your timing so it isn't too advanced, keep the boost reasonable, and you'll have lots of fun without turning it into a hand grenade. Attached image(s) |

I just bought it like this and am NIT wedded to this set up or even the engine (much to Mr Epstein delight). It would be kind of fun to figure it out but if it is a bad idea we can scrap the set up. |
