Pros And Cons Of An Rb30 Engine?

[Cubes]

700rwhp is 520rwkw.

People running on race fuel (so not PULP here) with 2530's make around 440rwkw with 25-30psi.

I dont understand this comment at all.

Just because its a 3ltr does not mean its going to mash out whats nearly 100rwkw ontop of already maxed turbos.

The fact is thats the limit of the turbos, they just dont flow anymore air.

You need GT-RS's for 700rwhp. Im not sure what level of gain Meth injection is going to give...

But just talking race fuel levels which is a level above PULP already, its out of the 2530's reach well and truely

Exactly.. The head and given cam select always determines the amount of approx power a motor will make regardless of its capacity. A smaller motor will simply require more rev's.

Dropping an rb30 under the rb26 or 25 head without touching anything else. All we simply do is shift peak power to a lower rpm.

the meth will allow more airflow and timing without the associated knock you would normally get.

Only problem with it is you need injectors twice as big as normal and a pretty good fuel system that wont perish, and can supply the required amount.

I get at least 1 PM per week asking this sort of stuff.

“I want to go RB30, but I also want to use 9,500 rpm.”

OR

“I like to rev my engines, so an RB30 isn’t suitable for me.

The problem is, if you use the 9,500 rpm efficiently on an RB30, it’s going to make 1,000 bhp or so. So what are you choosing to do, rev it inefficiently to 9,500 rpm? That makes a lot of sense, not. Much smarter (and a whole lot cheaper) to work out how much power you want/need and then rev the RB30 to that rpm.

Hence why the above are nonsense comments, stop looking at the tacho all the time and feel the horsepower. After all that’s what it’s all about.

Thx for the info guys. Most of my questions were for the future however, not right now. Of course there is no need to rev 2530's to 9500RPM on an RB30. Also they will be no where near the power that I am building the RB30 to be able to handle.

However I will be upgrading the turbos later and wanted to get some info for when that time comes.

Thanks.
