Downside is COST and COMPLEXITY.

srce,
have you talked to Howard Coleman about his setup? His name may have been mentioned early on in this thread, but what was stated was not up to date. He is trying out a twin t-04s setup right now and is just now breaking in the motor. He told me that he saw 5 psi of boost however by 2100 rpm. He has been working with majestic turbo, and I can't wait till his engine is broken in and then tuned so we can see what he gets out of that setup.

On that same thought though i'm probably wrong but wouldn't the whole complexity thing in turn make it less reliable? I suppose it would be different if you did your own twin turbo setup, but mazda kinda ruined it for me with the their version of the twin turbo system on 3rd gens.

theoretically more power = higher combustion pressure, so a 400hp 13b should have a certain amount of combustion pressure, we'll call it bo. when you compress air it gets hotter; hotter = more prone to detonation. we'll call that luke.
and we'll call airflow daisy duke.
so
the less luke you have the more daisy duke you can have for the same bo!
or airflow isnt the reliabilty problem its heat, or heat induced detonation
detonation is somewhere along the lines of 10x more pressure (plus a shockwave) than normal combustion, this is why it does so much damage
and we'll call airflow daisy duke.

I think what Mikeypoo is trying to say is that higher compression(more boost) will raise the intake temperature higher and thus increase the chances of detonation. When a turbo is in it's effeciency range(and below) the air it blows into the engine will be of a lower temperature than a high boost turbo.
Did I get Daisy, Sally, Jessie, Bo and Luke right?

Sorry, I don't even know who he is. When did he start his project and where can I get more details?
Thanks
Thanks
