Hi Net This reply is a bit late, but perhaps will aid anyone wanting awesome power. Getting the genie out of the bottle is not a problem, keeping the genie from blowing up the bottle is quite a bigger concern. I wrongly used the rational.---- Ford utilized a t3 in the turbo coupe and made 180 or so HP from their 2300 engine. In the Turboford.org forum, there are guys with 300HP and up versions. My 2366 type 4 VW has a shorter stroke then the ford and is probably making way over the magical 100HP. I was wrong in thinking that I actually had time in the cockpit to manually control the boost. I would always start with the waste gate open and set my boost on the roll, during the first few seconds after full throttle was applied. keeping control of the power is the essential part. Full boost would have been too much for the engine as it could easily make over 40hg on a cool day. After one more vehicle project I shall return to my KR engine and this time I plan to install a BOV.
I'm not sure an automatic waste gate is a good idea. at altitude, how well will it function? . I could not use full power and full boost at the same time between surface and say7000' I have been to 10 and still had plenty of boost at full power. I will probably have to fly it west to see what it can do. I have not had the pleasure of doing that yet. If I'm correct a smaller turbo spools faster but gives you less total boost. Orma L.
