My experiments over the years lead me to some definite conclusions & proof of improvements in the area of Thermal efficiency gains - Both DI Diesels & Petrol engines respond to this design change almost in the same manner - If done on the piston crown ! Provided the Piston has a Dish. You can run petrol engines incredibly lean without any hick-ups or heating-up or stalling !
( My simple way to prove this is to remove the lean setting carb from my modified engines & bolt it on to a stock / std engine & watch the fun - you just cannot get it started up - unless you keep blibbing the acceleration pump - next the water temp will go through the roof in minutes )
Back on my engine the same carb with the ultra lean jets will fire up almost instantly - same with the DI Diesels - instant start - with smoke & noise levels way down too !
I have seen just one deep groove is enough to define a total change. More the compression the better it responds - If you ever took a stock engine and just shaved 60 thou off the head and ran it on a stock cam & fuel - The end is not far away !
This design needs - Piston to head (Cold) at least 0.060" + for comfort ! You can drive them as slow as they can go, in top gear with out any jerks - Or hear any bells ringing - as you step on the gas ! You will Just notice Torque flowing out ! I have seen this happen in 2 valve heads with small squish bands too - the same effects with real large ones also - the same goes with 3 valve & 4 valve heads too - A little squish on 4 valve heads is enough to get it to work wonders - you don't need to play around with a lap-top to re-tune any of these engines ! Strange but true ! As this is a complementary design to present day ICE's with the least inputs. The plugs are a good indicator of what is happening inside - If you go real lean & mean - the plug's outer ring starts to turn blue - so does the cylinder wall ??? - But nothing ever happens to the piston crown, the valves or the seats ???? - as the water & oil temp just stays there - in case you have removed the thermostat - The temp will come even lower as you pick up speed ! This way, the Oils last out much much longer !
This " One " single design change to combustion chambers is enough to bring about a total change to the age-old IC Engine ! Mr. Rudy, a die hard - *Huds Only* - has freaked out after he modified his - Out of the Box - Hudson 6 - Twin carb engine ! He just cant believe it - He shaved off 0.040" of a brand new L head - placed a single groove per cylinder - & the death rattle never came back - he tells me - he can comfortably go up slopes in top gear doing 400 rpm on regular gas ! Without hearing any form of Ping ! Or see the temp go up !
All this must be sounding like impossible stuff - Most of it comes close to " Believe It Or Not " Stuff ! ??? From Day one - everyone is just stuck on Dyno results - Full throttle - Plotted Graph ! Is what we want to see Mr. Singh ! Do we see any gains ? ... If not, it does not work !
I would like to ask the World - How often does any one drive at full throttle? - Maybe at the Gasoline Alley - but certainly not all day in and day out at full throttle. Driveablity along with flowing Torque is what the World is looking out for ! It needs to start from rock bottom - zero rpm - this is exactly what the groove delivers & achieves ! Automatics just shift far more easily into higher gears while the rpm's stay low - Because you don't need to ' lay on the gas ' that much - lesser throttle applications are bound to give you the best fuel economy ! With my design you will pick up the desired speed - the potential limit lies with the lowest Differential ratio you can get your hands on !! You can actually drive cars at idle speed in top gear ! Nobody will believe this either ? Unless seen ! We do it every day. Read the pages. You can too. From a lawnmower to a snowmobile to hot rods and daily drivers of sorts. The groove works, and you will hear more about this idea that cannot be supressed because it is not a complex design or a riddle nor is it a " Secret" ! ( Any more ! ) Anyone can do it and this has been proven by the people who are visiting our website & other forums. Dear readers, you are also capable of performing what I do with a jewelers saw and a set of small triangular and round files. For those who need numbers, Dyno tests are in progress. I will not be surprised, and if you are, then you haven't been reading closely enough on the net ! Until Soon !!! Discuss this article on the forums. (0 posts)
