Posted: Tue May 02, 2006 9:02 pm Post subject: VW redrive thrust results

I made the first thrust test with my 1200 MK IV.  The engine is a 1915cc VW 

with a 1.6:1 redrive and 72" three blade Ivoprop.  I was disapointed at 2500 

rpm's static wot, but got 345- 370 lbs thrust at that combination.    The 

advertised potential for the redrive is 475 lbs with a 2180cc VW.

  I need to tinker and get my rpms up into the more productive hp range, but 

don't want to just start taking inches off the prop.  First I need to verify 

my tack, fuel mixture, etc.

   What do the other engines produce for thrust?   Anyone have numbers?  

Suggestions?

     Thanks         Ron NB Ore   N541KF

Ron,



Any answers yet?



Going by memory, that is about 70 hp worth of thrust. 

I drove VW's for many years, but they have not had a

lot of good results in most planes.  Some do OK and

they are cheap, but most of the ones I heard from

thought they were underpowered.



Keep working on the tuneup and see what happens.  The

potential is there somewhere.

Kurt I have heard on another list that a direct drive 1835cc put out 275 lbs 

thrust. I'm way over that and think I can do better with shorter prop and 

more ppitch.  I will try my 64" GSC to see what that does before cutting the 

72" IVO.  I have many other thing in the building stage so I'll post as I 

get results.  Ron NB Ore

Thanks Ron, 



Isn't this what we are all about?  Experimenting with

what works best and telling others?



I don't think my prop is the best for my engine, but I

don't "know" what is best.  It may require different

gearing for the engine to match the prop, or a

different prop to match the engine.  It sure doesn't

seem like 140 hp worth of thrust up front to me.
