Default Not your typical grooving!

http://www.somender-singh.com/

While on youtube, stumbled into some video clips which ended with the above link. Seems very interesting idea, instead of polishing and smoothing out the chambers, extra grooves are placed on the cylinder head to maximize engine power. Like always there are both sides of the story, decided to share my bad *** discovery to the online miata community.

Below is a little ghetto video clip found on youtube, posted to those who prefer visual information.

I dont know if this is a fail or there is some win to the above information.

I'm sure this is legitimate. I hear slicing grooves into the head is what all the high-end race teams are doing these days.

your badass discovery has been around since the Bloodhound Gang debunked magnetized miracle strength tonic.

There was an article in popular mechanics about this guy a while back. On the motors this guy has access to it works well. But these are also smaller displacement, and typically very OLD engines where the head design is crap to begin with. Most of the engineers that commented on the guys work said it would probably not do too well on a modern engine.

while everyone building powerful engines smooths just about everything down this guy roughs it up.

I see prostock heads every day from almost every team. I've never seen one with those grooves.

Yeah even in v8 stuff I've never seen a set of cnc ported afr's,edlebrock's,dart's, ect with such things. Its ideal to have a rougher finish in the intake port to help atomize the fuel. But grooves in the chamber= hot spots

I guess its been a decade since I've had a look but those were supposed to be the rage at one time at least.

so...how the hell are they getting insane power out of 500" motors?

I know I will get flamed for this, I have done this same mod on nitro fuel engine, not gas powered, (20%-35% Nitro) and the improvements were noticeable. Two things were evident, much better top end, and better fuel economy.

The mods were done on .12, .15 to .26/.28 nitro engines on the crown. I know it is very different, two stroke, carb setup, nitro and displacement. I would have harder time tuning the smaller engines, the big blocks like the .28 would run way much better, although I went to crazy on one of the crowns and messed up the idling.

by using jesel valvetrain! hp is a function of rpm baby.

The more crazy thing is how can the entire field of 16 be within .06s when there's so many different setups...ford, chevy, dodge engines, wedge & hemi style heads, different chassis setups, etc. Nuts.

EDIT: I will try to remember to bring these up next time I talk to some of the engine builders.
