I think you should change the cylinder head bolts, because they are torqued to yield (usually) and cannot be reused.

Diesel engine normally operate at higher compression ratios & ignition is automatic hence may be its difficult for groove to impart benefits.......

Also if we can find good amount of increase in torque then theoretically HP must increase.........but not tested so far......

For timing belt if adjustable tension is not sufficient then we need to change timing belt.......in my case I found it advisable to replace....also with different car there is different amount of material to be removed from surface so in some car we might need not change it...also I think changing head bolt is good measure for tighter fitting with right torque......

Enjoy....

Hey guys....I have a question on post-grooving torque:

When Kaizer and Finetuning mentioned that they are able to drop to low speeds even in higher gears (i.e. 20 kph in 4th) without knocking, does this mean that the engine rpm is also at or above idling speed?

I haven't gotten my engine grooved yet (running into schedule problems, you see), but I have got my Ikon 1.6 to run at 20-ish kph in 4th without knocking. However, the engine rpm sinks to 500! Is this the case in a grooved engine? I would think not.....

By the way, finetuning, my vehicle would not have been able to do even that (above) without acetone! so props again to you, man, for the evangelization!

Hi vezj420,

Infact I can drive my car at 4th leaving pedal with 4 persons......normally on 4th gear we cant drive with full load at idle speed....suppose after touching speed of 40 on 4th gear we lift acce.pedal then slowly it comes down to say 20 or so when we get knocking..jerks and car engine stops..means engine torque is not sufficient enough to carry load at 4th gear at very less rpm.....

Driving at 20 on 4th is the indicator of plenty of torque at said rpm......this is a boon in city traffic....we can travell on 3rd throught including nicely carved bumps....in no way stock car can perform like this....at idle speed normal air fuel mixture is not sufficient to produce enough torque to behave in this manner but with grooves there is great amount of turbulence in both compression as well as power stroke(mixing air & fuel in most efficient manner) hence with same amount of air fuel engine produces more power which is capable of driving efficiently in city traffic....

If your car doesnt knock at 20 kmph on 4th gear then its producing excellent torque.....try this with 4 persons.....with grooves you can then travell at 15 or perhaps 10 or 5 kmph on 4th gear.....this seems unbeleivable but is very much true.....keep using excellent acetone in right amount....

Enjoy....

anyone in chennai who has tried the grooving on their cars pls PM me. I am one step away from doing it and i sure could use some advice..... and probably a ride in ur car.

FT, u got me there! I got to 20 in 4th with only me in the car, and I guess I was on the threshold of knocking.....rpm had sunk to 500, but interesting thing was the car was moving without jerking!

u still didnt answer my main query though - when u get to low speeds like 20 in hi gears like 4th, what rpm does your engine stay at? is it right around idling speed or does it sink below that?

My Zen idling rpm is around 700 without ac. even on 4th gear the rpm is around 900-1000.
does this ans the question?

[vezj420]

yes, it does....thanks Kaizer!

[finetuning]

Hi vezj420,

My car doesnt have rpm meter but I feel its not going below idle rpm on 4th.....it must be around 1200 to 1500 on 4th gear......I think kaizer pointed rightly on his zen...anyway your car is producing wonderful driving charecteristics which can only be enhanced with grooving.....beleive me it will be a great fun to drive grooved car.....Excellent DRIVABILITY is the main outcome of groove work apart from other benefits.....

Now after grooving with even full load you will be able to drive on 4th at idle speed......you can then simply accelerate from 20 to high speed without changing gear.......also after 40 kmph
we feel a kind of boost when we press acce. because of turbulence in combustion chamber......

Anxiously waiting for your groove work & results.....

As said grooving will impove the FE and also the torque.Is there only a marginal change in performance or much more than that.

cheers:

[finetuning]

Hi NFS,

I think you need to read thread carefully as everything is shared...

Now after grooving there is good amount of increase in performance....its not marginal.......

Enjoy...

Hey everyone! This seems like a great thing to do! A great invention indeed. Hats off to him. So I was reading this thread. But I somewhat got confused. Someone here said that after grooving, the engine temperature decreases, and so the ecu gets programmed to provide more rich mixture. Wouldn't this reduce the FE? I know its a YES, but then how does the FE become better? Or after resetting the ECU, the ECU adjusts to the new low temperature as its normal temperature?

I have a Ford Ikon 1.6 2005 model. Whenever I try to go in 20 in 4th gear, it gives a force to get back to 1,000 rpm. No knocking tho. But I really like the thing of "full combustion" to get more mileage and torque.

On an earlier post, some one told that Mr.Singh would be stopping work and getting to concentrate on R&D.

If yes, then if I want to groove my Ikon 1.6, to whom should I go? I felt I should go to him only because he's the inventor for this and the pay should go to him only.

Still, is it possible to groove the Ikon 1.6? Would love getting more torque and mileage from it!

Nope my engine temp has not decreased I have an mpfi engine. The grooves can be done by any skilled mechanic, just call mr somender he will guide you.

Hello Kaizer! Thanks for the update. I will contact Mr.Singh and get details from him. Thanks for the update on the engine temperature. However, has anyone already done it on a Ford Ikon 1.6?

[Absar]

Hello? This thread gone silent now..? I mailed Mr.Singh and I'm waiting for his reply regarding the grooving steps. I'm actually a bit impatient to do it for my Ikon 1.6. Btw, does this grooving job take a long time liek 3 - 4 days including the head removal, shaving, polishing/lapping, grooving and fixing the head back or is it possible in a single day? I might be travelling on a 800+ km trip next week (7/3/07-9/3/07) and I want to do it with a grooved engine.
