How much hp can b48 handle on stock internals

[chowser51]

Why did you start a new thread?
People were answering you.

Best answer: get a b58.

hey bro some one told me to start new one as idiots were not and=swering my origanl question

[oem.plus_440gc]

Did you look through the B48 engine modification thread on the forum at all? What are most people running for power? Typically you're not going to have much to gain outside of the OTS maps until you go big turbo/meth injection/port injection/etc. So my honest suggestion that should really answer your question is... stick with bolt-ons and an OTS tune. If you want more than that and have to ask this same question multiple times, you haven't done nearly enough research to go past the bolt-on level. If you're serious about making more power than OTS/bolt-ons give you, it's time you start doing serious research, call up tuning shops who work on and tune B48s, and start making connections with others who have gone past the bolt-ons stage with the B48. Asking the group is going to get you the same answers you got on the last thread (which i also answered you in).

Big power on a small engine means big money and big knowledge...

Sorry, but this is just dumb. If making big power is your goal, you bought the wrong car. Sell it, buy something else and save yourself a ton of money and headaches. You can dump $5k into that car and still not have more power than just buying something else. If you can’t afford an M3/M4, buy a B58. A simple downpipe, tune, and some E85 and you’ll have 5x the car you have now and still be very reliable.

Unfortunately, there is only one common idiot in both of these threads. ....and that person started both.

nice man the conversation got changed
I wanted to know how much hp a b48 can handle on stock internals
And it changed to turning 330 into m3

When you don't get the response that you want be sure to start a 3rd thread!

No offense (ok, actually offense), this is a cut/paste from your first post on the last thread. It was you wanting to make it a M3:
"How much hp can b48 handle on stock internals
i have 330e and want to knwo how much hp it can handle.
I want to get the same performace as the m3 f80/g80"

but yeh, why not open a third thread to see if you can get a different answer. Would be good if you could confirm Einstein's definition of insanity: "Doing the same thing over and over expecting a different result"

We’ve gotten a stock b48 low compression to reliably hold ~475 whp for a couple months BUT OP apparently doesn’t know how a turbo car and/or what is involved when pushing limits for boost/timing/oil pressure/etc to keep it alive when reducing safety margins.

Doesn’t cost a lot to get there, but since OP has no idea how this works, it’s best to stick to off the shelf “stage 1 stage 2” maps or buy another car

[chowser51]

There's a whole B48 section here:
https://f30.bimmerpost.com/forums/fo...play.php?f=422

start a third thread there and get the same answers.

so i should go low compression if i want to go high hp
thanks for the good knowlege
ps what comression number was he running

bc my question was not aswered everyone changed it to making f30 a f80

[MidtownMike]

I told you bro you can get 700hp out of a B48 320i. Just do it bro.

Somewhere between 300-350 HP. You aren’t getting M3 levels of power and keep it reliably. Stick to OTS tunes or get yourself a B58. Did that answer your question?

It won't.... this is the exact response i've given 3+ times to him in 2 threads as well as a ton of other people. He's dead set on MAX power possible on a B48.

[Wires]

Looks like you are trying to make it a G80 M3, you need to redo all the suspension, engine and drivetrain. You'll need the water injection like the M2 competition for maximum power.

Happy OP? We've turned it around to "you need an actual M car again!"

Patiently waiting for thread #3 to open.....
