Nothing a few bucks, some time, and a dremel cant prove or disprove!

Lol

I got a buddy at junkyard, can get stuff for like half price. So.... Yeah


generally, im all about things being scams. And I dont deny this may b one. Bit there have been a lot of cover ups also. Cant figure out unless its tried by friends or yourself

 

Even if you do the work there will be no way to verify the change did anything positive (or negative for that matter). There are just way too many variables for any one engine to prove or disprove.

Until one or more credible labs do a double blind test with several engines to prove (or not, most likely not) the efficacy of these grooves, then I deem this a scam, plain and simple.

 

You would have to run the engine with the heads without grooves for quite a while to get enough data. Then groove the same heads and run the same amount of every variable to get any reliable data. Changing from one head to another can change performance anyway.
I'm leaning toward another Al Gore "global warming" scam.

 

im just curious guys, how could this b a scam if u do it yourself? obviously singh cant do em all and rake in all the dough...

 

It's not a scam so much as an undocumented modification w/o any (that I could find) definitive testing.

Only testimonials to support. Some testimonials are compelling, but then you see lot's of folks tout Cold Air Intakes as providing great improvements in acceleration and fuel economy. I know those are erroneous.

Carl Sagan (for other reasons) said something like "extraordinary claims require extraordinary proof". That applies to singh grooves for sure.

good luck

 

I like the way u said that Texas. If I ever do that, then I will document the whole procedure I take, and post that as well as results. But thats a long ways away if its going to happen.
