I'm going to explain what is going on in the clearest way I can so that everyone understands what is going on while protecting the integrity of the engines.
There are two engines that we intend to sell to the public.
The first engine is the one we have been working on for two long years
It was to be built a firm in taiwan. it is a long rod 12 engine
specs. It is a brand new ground up engine
13.98 MM bore
14.06 MM Stroke
Long connecting Rod
3 port with RTU gen6 style porting and timing with full cnc blending
12 MM 4340 billet steel crank RTU gen6 fully blended and radiused on a cnc. RTUgen6 timing
fully blended turbo cut on a cnc
conventional turbo and standard head buttons
2 needle carburetor similar to an os carb. to be scrapped in favor of a three needle design
The development of this engine is done as far as I am concerned and anyone who has seen one or driven on will tell you they really cook. However during the development we have had issues and still do getting the manufacturer to produce it. they just cant seem to get it together. So a couple weeks ago a decision was made to transfer the production to another firm. We did all the development on the engine so as far as we are concerned we own it. This obviously will take a few months as the new firm will have to redraw all the parts for us and make new dies set up machines etc. At this time we are confident that the new firm will step up and we also are sure we will recieve an even higher quality product in the end. This engine has yet to be NAMED.
The other engine
13.80 MM bore
14.04 MM Stroke
short rod
stepped steel crank
our timing and fit specs
3 needle carb
In not wanting to put all the eggs in one basket we have been working with another manufacturer in taiwan to launch a short rod 12 engine. we had some initial performance issues during summer testing but those are solved and testing of the short rod motor is showing to be good enough that our version (we asked for a number of changes internally) is on order and some are comming in as we speak. They have made the changes I asked for and these will be sold as Richey Racing Engines also with the RD logics logo on them. These will be based on an STS block and crank but will be different enough we will market them as new engines. This is similar to an serpent picco situation. thats the best way to describe it. These are the R3 and R5 engines. you should see these pop up on the RD site in a week or so.
Hopefully this sheds some light on the subject for you
Dennis- is there a typo on the specs?
13.98mm bore
14.06mm stroke
displacement= 2.158 cc's or
0.1320 cu/inches
13.80mm bore
14.04mm stroke
displacement= 2.100 cc's or
0.1280 cu/ inches
ROAR rules allow a max of 0.1290 cu/ inches on all .12 size engines.
IFMAR rules allow 2.11 cc's.
I guess the long rod engine will not be IFMAR or ROAR legal??
