Your knowledge of cars is miniscule to this guy

ohh yeah i've seen that guy before. i love those cuts he makes in the head, and even funnier is he has patented it

oh, and of course welding the clutch is fairly awesome too :|

[driftke70]

how does he even begin to think those grooves in the head will do squat, ,

and god knows where he pulled his 900hp estimate,

[Sturgey]

lol that is all

[Chairs with flares]

While the application of the theory is astoundingly stupid in that build thread, there is merit to those little grooves in the head.

They are called 'Singh grooves' after their developer Somender Singh, who holds the patents to the design. As long as an adequate quench clearance is maintained (piston to top of head distance) the grooves act as vortex generators to agitate the air/fuel mixture in the last part of the compression cycle. The keeps the mixture vaporized for longer and reduces the amount of fuel vapor from condensing back into fuel droplets; which burn slower. The result (when done properly) is a cleaner burn with a faster flame front, which reduces the chance of detonation through the cooling (or slower heating) of the air/fuel mixture, and reduction in piston/head hotspots.

Another side benefit is that since the fuel mixture stays a vapor for longer, race motors; even running rich; can idle smoother at lower RPM since the mixture burn is quicker and cleaner. Since the burn is much cleaner, there are less deposits on the piston and head, adding to longevity of parts.

This also allows higher compression (or more boost) before detonation occurs. Alternatively, due to the quicker burn times, ignition timing can be set closer to TDC so there is less 'wasted' burntime, i.e. combustion before TDC that slows piston speed.


Without grooves.

With grooves.

You can see the grooves; one at the top between the valves; one near the spark plug hole and a small one in the lower right part.

i just read all 63 pages and watched all the vids....


that is plain fucked up

i cant click the link as im on limited download at uni.

ive read it before though, didnt get get some phenominal HP from some dodgy ass setup?

from what i remmeber, he did all the things ive always wanted to try, but never had the cash to throw away:P

[rthy]

love the air box

[dave2221]

i should order my new clutch off him.....

that thread is gold

[trueno85]

hahaha my dog was watching the first video of it running and the entire time it was watching it, it just tilting its head back and forth and barking at it! basically explains it even my dog knows he's retarded!

[shichi~]

Wtf????

[The Enthusiast]

I tried to see how long i could read this and look at the pictures without laughing,
i broke down into tears when i seen the gear box starting to get painted blue

the concept is marginal on an 8 valve, on a 16 valve more than pointless

[ke_70]

i cant belive it runs!!!!!! i thought the valves would hit

omg im totally doing this to my 4ac

[ke_70]

omg im totally doing this to my 4ac

make sure u giv it a good coat of blue paint

[corknose]

haha lol i just read the whole thread omg

[Mr Awsome]

did he seriously paint the top of the fucking pistons?

UBER EPIC...

is there any honda threads like that? hehehhe

[Sam-Q]

I dont get it, in some parts he seems to be doing what might be good then he just tottaly stuffs it up. What I dont understand is how is doesnt get the concept that the engine moves when its being used and that flex joints are need for the intake pipes and so on

[Sam-Q]

ok I just read to the clutch part and had to stop myself foaming at the mouth

This has really done the rounds, I first saw this post when it was only about 15 pages long. I still piss myself when I read it.

[pen15]

this bloke knows his shit for sure i want to throw him 1 million to build my next motor


WHAT A FUCKWHIT!
