Block Guard Or Posting?

Re: Block Guard Or Posting?
Sleeves crack because of cylinder pressure. Lets say a stock engine at peak torque your cylinder pressure is 1000psi. Well 400hp, the cylinder pressure will be significantly higher. For numbers sake, we will say its 3000psi. Now you are already taking the sleeves 3x times the peak cylinder pressure found in a regular engine. Now if detonation occurs(which is essentially the only way to destroy sleeves other than a block overheating to hell, but even then detonation normally causes the destruction), the peak cylinder pressure wont be 3000psi but double or triple that number. That increase in cylinder pressure just destroys sleeves. Aftermarket sleeves handle higher cylinder pressures better due to the metal used thus allowing some detonation to be tolerated. At extremely high hp levels, your cylinder pressure is nothing compared to moderate hp levels with severe detonation.

Inquisition - good thread, and suportive information
beerbongskickass - good link too, detonation *thumbs down* yup its all in the tuning!
i feel a little better now about just running stock sleeves.....
