this is reference to another post.
What is the difference between having a turbo ls/vtec at 300whp and a 300 whp ls/vtec with high comp and no2 making the same power?
This question is in reference to how te sleeves would hold up? Because in the other post people were stating with the motor +no2 setup the block would need to be sleeved and the turbo motor at 300 stock sleeves would be safe. These setups would have good tuning as well.
This is saying the motor car is making between 215 and 230whp + a 75shot(wet) and the 300whp is just a reference #.

I recomend the Nitrous setup.

 

What cracks sleeves is the cylinder pressures. When you detonate your cylinder pressures go sky high. They key is the tuning. You can tune a turbo car and get a consistant tune. With nitrous you have other variables like bottle pressure which change the effect the shot of nitrous has on the tune. You can tune nitrous but when pushing the limits of stock sleeves if you push it too far you will crack a sleeve. The way people make great power on stock bottom ends has to do with fuel management and the quality of the tune.

 

I agree with what that ricer said ^^^

Another thing to take into account is the fact that generally, nitrous makes more torque, so when compared, if you have 2 bone stock GSR motors, one with nitrous making 300whp, and one with a bolt on turbo kit making 300whp, the one with nitrous SHOULD make more torque... Remember what qitstrn said, cylinder pressure is what cracks sleeves, and torque has a direct relation to cylinder pressure, so the motor making the more torque, most likely the nitrous motor, will have the greater cylinder pressure, making it more likely to crack a sleeve...

 

thanks for the answers, i was thinking it had to do with cylinder pressure,(low compression=less cylinder pressure) but was unsure. thanks for the responses
