Here is a project that I have been working on for a couple of seasons that ought to stir some conversation. Or perhaps get more to thinking about that winter project. I am incurable when it comes to tinkering with motors and always looking for optimum performance from my "C". I came across an idea from a friend who told me about cutting grooves in the squish area of a head on an internal combustion engine to improve gas mileage in his 54 Ford Pickup.In fact I think I mentioned this on the other forum once just to get some input. So with tongue in cheek I put it to rest. But I couldn't stop thinking about all the experiences I had read on the Singh Grooves when I researched his site and followed scores of threads. In fact google Sing Grooves and see what comes up. Follow some threads. Or go to the Web site http://www.somender-singh.com/ or http://www.mgccars.com/groove_101.htm [speedtalk.com] See Automotive Breath. This guy has something here. Best of all it only costs a little time and a couple of gaskets.
By substantially increasing turbulence within the cylinder the Singh Groove enables more of the fuel to be burned and it burns at a faster rate. This promotes cleaner engine exhaust, cleaner oil, more power, lower operating temperature, no pinging and significantly increased engine power at all levels. Since fuel is being burned more completely, the engine runs clean and cool.
I will list a number of improvements that I have personally seen by cutting grooves in the head of an internal combustion engine.
1.) Run your vehicle on 87 octane pump gas with no pinging.
2.) Increase Fuel Economy 20-30%
3.) Increase Hp
4.) Increase Torque at all rpm levels
5.) Lower idle-not unusual to see 500 to 800 rpm and maintain smooth engine characteristics and smooth take off
6.) Lower engine and exhaust gas temp, typically 20 deg cooler = longer engine life
7.) Maintain clean oil - if this was all it did it would be worth it.
8.) Raise compression if you like. Recommend 10.5 to 1 and maintain .070 squish area, but will work with less. And still run 87 oct pump gas
9.) No other mod will get you this many benefits for the cost of a couple of gaskets
This car runs so smooth that I can idle it down below 500 rpm with no problem, however because the alternator needs more revs to come on I have it set to the 600 recommended by the factory. Maintaining N temp reading is routine. Mash on the throttle from 500 and it revs up w/o hesitation. Drive along in 4th at 1200 rpm, give it throttle and it will pull with no chugging. In fact the man who discovered this sometimes refers to it as direct drive. It has great low end torque and increased the power band from idle to farther than I wish to push it. I'm sold and have plans on doing another MGC as well as a set of Harley Heads. This is something any of you guys can do with just a simple dremel tool.
