Hydrogen, its effects inside an engine.

The Singh grooves on my very In-efficient Heads DID Help a lot.
As far as your motor, I would look at the list of pics that are on his site
to see if any are similar to yours. But it sounds to me that they have
already introduced a similar technique on your combustion chamber.
Unles the two notches you mention are only for Valve clearance. I dont
think that they give as much Benefit in MPG as the Vapour carb.

They appeared to give similar results to a very low level of Hydrogen Boosting.

I hope to get a better HydroBooster on my car in next six months and then
I will be Leaning off the petrol, to see how good I can get it.

Glenn,

I had to replace the head on my 2.5, and the old head was swirl ported, and is a heart-shaped cylinder head. The new one might be swirl-ported, but has oval heads which offer no obstruction or turbulence. It's what I consider a 'dog' head as its compression dropped from 9:1 to 8.2:1.

The hp rating between the 2 90 and 88 respectively. The ft/lbs of tork is about the same. This engine is a long stroke engine and redlines at 5k. It has good low end tork, and works well with a 2400lbs car. This car has 4.10 gears though, so at 3k rpm, we are looking at 70 mph... Still gets 30mph though.

I have been studying heads for a little while now, and it appears that the singh grooves are really beneficial to run an ICE with much higher compression. The engine that I have isn't worth the trouble milling it down to gain compression, but it appears that the grooves allow for a more complete burn, reducing or even eliminating pinging/pre-detonation/knocks, thus, allowing for increased compression, advanced timing, and more hp, tork, and fuel efficiency.

If you look at all the flex fuel cars that are coming out to run E85, they are much higher compression engines. I am willing to bet that these late model flex fuel engines are engineered to create ample turbulence for a more complete burn.

Just a quick question concerning this topic. Someone recently told me that using an EFI motor would be superior to a standard carborated motor due to the automatic computer controls of the fuel/air mixture?
That seemed logical to me, then I began to wonder if the new flex-fuel vehicles may be a better platform to test these boosters on. They have, I've heard but not confirmed stainless valves, injectors, feul lines etc which would eliminate the corrosive nature of the gasses.
Plus; when tuning the motors with the new fuel mixture; they already have the diagnostic boxes and adjustable parameters available.
I'm no where near testing this yet but wondered if any of you have, or can correct my assumptions.
