  • Sounds like you have it well planned. I would prefer to see liquid lpg for better control/less exploding intercoolers but the stepper motor control is better than nothing. Don't discount ignition control on the engine though, ignition timing makes a big difference to response on the turbo and general engine efficiency. It will be particularly useful with det resistant fuel like LPG.

    GT35 is a reasonable choice for turbo given the capacity but without knowing specifics of the engine such as compression ratio and trans choice it is hard to be specific.

    Sounds like a cool project, look forward to seeing it in members rides or build threads.

      Thanks for the quick reply.
      Stock compression: 9.0:1
      Trans will be a three speed auto, stall converter ~2200rpm due to cam.
      Will be in a 1450kg '72 holden panel van.
      The mixer ring sits 90mm above the carby (TB) butterflies, with a volume of <1.0 litre under the mixer, so unless something drastic happens the intercooler sits nearly a metre away from the lpg input and will hopefully remain atached. And if it backfires I will try and design the plenum to let go first.
      How strong will the plenum need to be? - say 10psi x (average 4bbl aircleaner internal surface area) = a lot of sq inches! I had better put some ribs into the design.

      And where is a good place to get steam pipe bends and sections in Melbourne? And, is good penetration gas or gasless mig going to make exhaust headers that will last?
      Too many questions, sorry! Thanks again.

      • Hi ive got a 800cc three cylinder daewoo matiz i was thinking of boring it to a 900cc and turbo converting it and was wondering if you know of a turbo system off another car that would do the job right without killing the engine ive been looking into it but theres not alot of info out there for this little tiny engine lol. Thanks turbo yoda

        • would forced induction work at all for nitro rc motors?

          sure as you said, small motors cant make enough air flow to get a turbo spooling, but im not specifically talking about every day turbo, im just talking about the principal of forced air induction on a nitro motor. would it have any benefits at all?
          i suspect it would just lean out (even with adjusting of air/fuel) and it that it may be the same as turbocharging a turbo 2 stroke - the air just passes straight through, no benefit.
          this is .18cc
          so, its about .00018 liter motor? XD they rev incredibly hard however

            What course of chuchu do I take, any small enough turbos around??

              It would work fine on the 4-stroke models, on the 2-stroke ones it would only blow unburnt fuel/air mix into the exhaust, and increase fuel consumption a lot while hardly/not increasing power..

              Garrett GT06 comes to mind, for 100-500 cc engines, very nice for go-karts, mopeds and other small displacement stuff..

                  i have that exact engine on my monster truck the port design in them does not lend itself to boost of anykind 4 stroke nitros are starting to trickle into the car market and once they do you bet people will ad boost quite quickly. and beleive it or not there is already turbo's small enough for these things. the first things that come to mind are rc tractor pullers and rc drag cars that have been custom built to run 4 stroke rc plane motors already running boost
                  the build it started as show and quickly turned into GO!

                    RBInnovations have been making supercharged nitro rc motors for quite a while.

                    • Too bad supercharging a 2stroke like that only blows out fresh mixture through the exhaust while hardly adding any power..

                      • sooooo I got a 2008 mazda 6 2.3 l, Im sitting at 125hp and 125 torq, all I got is an intake and thats what I dynoed at ... I want more power and I have been thinking about forced induction, this is a car that has never given me any problem no matter how hard I drive it so I dont want to get rid of it, Im a college student so I dont have 2000 cash to put on my car on one sitting so

                        I thought of a turbo, but this include many parts, my car can handle a turbo at 5-7 psi without having to do support mods on internals, so why spend 5k on a turbo if I can only go up to 7 psi, next idea was supercharger !

                        on the supercharger gains what are they? Also what parts do I need? as basic the supercharger, belt and ?...

                        Comment


                        • 7psi with hardly any timing took the mx5 from about 80kw to 110kw.. nothing to sneeze at!

                            Here is what ~ 4psi does to a 140 flywheel Hp BMW. The car uses my phantom supercharger set-up. ~ $1200 all in.

                              • I'd assume another term for going past the turbo's RPM limit, pretty much any condition that falls outside the compressor map causes this (too much boost (=wastegate stays shut), too little flow at high boost levels (compressor surge) or too much flow. (compressor stall)
