But it's only my opinion, others may disagree Really nice journal and love the work going into this | ||

But it's only my opinion, others may disagree Really nice journal and love the work going into this going to have to use the gt20 turbo as theres no room for a bigger turbo standard pressure is about 10 psi at the moment was running 15 psi but didnt feel like it was safe on standard rods and pistons so maybe i could try that first | ||

Expert Posts: 5629 Location: Letchworth/Basildon | Yeah wouldnt feel too comfortable running any more than that. I would worry about inlet temps but you can moniter these cant you? So thats great! With a gt28 you could run 15psi but be in a whole new league of power. Proably not what you're aiming for though  | ||

So thats great! With a gt28 you could run 15psi but be in a whole new league of power. Proably not what you're aiming for though I dont get this, if 2 turbo's are both making 15psi at 4500rpm for example how will one make more power than the other assuming 15 psi is within the efficiency range of both? I can see the bigger turbo making the same boost at higher rpms but if the small turbo is not outside its comfort zone in the RPM range you require why would a bigger turbo make more power? | ||

Its because the bigger turbo will flow more air at a given pressure than a smaller one. This is kinda an extreme example http://www.youtube.com/watch?v=qrb2sBGI8Sk | ||

This is kinda an extreme example http://www.youtube.com/watch?v=qrb2sBGI8Sk That does not make sense, boyles law says that air pressure and mass are intrisicly linked so if the pressure is the same, the volume of the container is the same (same engine) and the air temperature is the same then the mass of air is the same. You have to run higher rpm's to run lower boost so its all a trade off, make an engine capable of running boost or high RPMs or both if you have deep pockets.
