How NOT to build a car from the ground up
#21
Checked out some info on Singh grooves. Haven't really heard any negatives about it. Has anyone found any empirical data on this?
"I've done several grooved heads, both NA and turbo applications. 2 Saturns were raised 1 point from 9.5 to 10.5:1, both running 87 octane, neither activating the knock sensor (checked with a scan gauge) even at 20 mph 1/2 throttle in 5th gear. Turbo applications seem to be good for about 4-5 psi extra boost on same fuel."

Oh my dear lord! I feel less intelligent having seen that.
What color is it anyway? Blue? Red? Gold? Silver? Bluish-gold? Reddish-silver? I can't tell.
I love the self balancing turbo,though! It just flings the excess weight off all by itself!

Am I the only one that just got angrier and angrier the more i saw? I swear people like that just need to be homeless...with aids...and leprosy to rot away the hands that ruin peoples (idiots) cars and lives. I cannot belive that theres a group of people THAT stupid. And whats worse that the idiot who took his car there in the first place has taken it back there multiple times after multiple failures. Wow.

Alright. After reading the Singh information, this is my understanding. The grooves or lines are created to expose more of the air fuel mix to the spark plug upon ignition and to help create turbulence in the quench area for better mix and burn. In theory, as the piston hits TDC, the fuel outside of the quench area is not directly exposed to the spark plug, meaning that it takes longer for the total amount of fuel to burn during ignition. With these Singh groves, you introduce the fuel outside of that quench area to the spark plug, without increasing the volume by much. This also allows mixing of the fuel and air during compression.
That's what I got in like 5 minutes of reading, so if I'm off base, then I'll have to read again. I'm gonna look into this more anyhow.

Look at the Miata though, probably one of the most reliable stock cars there is. But if you want to make over 250hp reliably you need a new rear end, new tranny and maybe a new bottom end.
