The world's greatest engine tuner

So those sin marks appear to be terrible attempts at Singh grooves. Doubt the ones pictured will do anything, but well thoughtout and well cut grooves can actually net a signifigant increase in lower compression N/A motors, and relatively high compression two strokes.

No. When his website looks like this, you know he's smoking crack: http://www.somender-singh.com/

Also, yeah, we had a thread on this back when it was recent

There is a lot of idiot in that thread and its not all from the dumbness of the guy building the car. Glad i didnt read every post and just skipped through the pages with pictures.

Yes. The website sucks but the grooves do work. They are more like a bandaid fix tho. It would be better to have a perfectly designed combustion chamber and compression level for your specific tune and application- but that's just not possible.

I will admit I cannot vouch for four strokes benefiting from them, but in the world of two stroke tuning where I come from they are an accepted and tested modification. They usually result in more complete fuel burning and crisper engine operation, and even reportedly lower egts. Again, a perfect combustion area would be better- but come on.

You're absolutely right.

Brb, getting some duct tape and a screwdriver, aiming for 900hp.

Dont forget about 10k rpms. That is a must. Esp when you only end up with 386hp at 7k.

But common dude, that was only at 2 bar and there is 3k left to rev too.. I think he can get 600 more HP with it with 3k more rpm's

I'll be running 14.5k rpm. I ain't no bitch.

2 stroke =/= 4 stroke
