عايزين مهندس ميكانيكا وميكانيكي دماغو نضيفه :d

والله ياباشا الكلام اللي انت بتقوله حلو بس للاسف يصعب علي امثالي فهمه :d بس ارجوك متكرروش لاني بردو مش حفهمه :d تفتكر ايه الطريقه الصح اللي ممكن تتنفذ بيها الموضوع ده وازاي تقيسها علي اساس ايه يعني ده اللي عايزين نوصلو عشان نقدر نطبقه ومستني ردك

Many people want to know how they can cut their own groove. Here are a few steps to the process.

1. Chose a engine design that has some form of squish or quench. Consider both the piston top and combustion chamber when deciding.
(e.g. dish pistons reduce the squish percentage considerably.)

2. Run a base line test with regular pump gas and production compression ratio, normally near 8.5 to 9:1?

3. Remove the heads and raise the compression ratio up to 10:1, milling the heads is the preferred method.

4. Cut one groove in each combustion chamber like the one in the pictures. So far the straight channel seems to work the best.
(if using a SBC, the grooves will measure near 1 cc volume)

5. Ensure a 0.070" piston to head clearance is maintained, measured at engine assembly. Most hot rodders are tempted to raise the compression by reducing the piston to head clearance down to 0.040" or less, resist the temptation.

6. Bolt the heads back on, leave the tune up alone, measure and report the improvements. Check and correct the tune up as needed and put it in a car (dyno's aren't much fun). You won't be dissatisfied.

شكرا ياباشا علي مشاركتك وربنا معاك ف المذاكره بس قوم من ع النت :d
