dont most of you think that you are gettign too big of a turbos, i mean most of you it seems run mo more then 15 psi, and that is way too little for turbos such as the t56 and up. you get shitty *** low end you hit full boost by 5k rpm and the car is dog do drive around. woulnt it make more sence to just get somethign smaller and have a much bbetter power band where your car woudl actualyl be FASTER then the one with a bigger turbo not evenm talking about how much easier and more fun it woudl be to drive. it seems most people here dont do their homework for the type of turbos they buy. usualyl the most whp i see here that peopel post are aroudn 400 i mean a small to medium t04 can do that. whats the point of gettign these humongous turbines? do i not see something? or are u just gettign teh turbine for the bragging rights and how BIG it will look when u pop your hood aka (ricer). it seems most peopel only get here half of what teh turbine can do which is NOT a good thing you want to be in its EFFICIENCY range.

I think a lot of people do it for the name. A lot of people try to build dyno queens. It's all about the props.



To each his own, eh?

While some single turbo's are "too big" for the street, there are some that are too small to make anything much over 400rwhp on street level boost. Its a small sacrifice to give up 500-1000rpms over a small single struggling to get to 400rwhp, when you can have 425-450 easily on a bigger turbo that won't die off on top end.

if you dont die off at teh top end thenu are sacrifying a bunch of low end, its better to die off and make more power inteh midrange then never to fall off.

Depends on how big of a turbo you go with. You don't necessarily loose a ton of low end. The t62-1 I ran had awsome low end, and would make my apexi turbo look like a turd all day long. Who races at low rpms anyways? If you have midrange and topend, what else do you need?

I'm not sure you have ridden or driven many rx7's with single turbo's. I had full boost at 4k rpms and making hella power from there all the way to 8k rpms. Again, its how you size the turbo to what you want. You CAN have good low end and good top end with a single turbo. It might not be that perfect stock low end, but its close enough for what you gain everywhere else.
