Anything else under there? The 3 bars are good for 29psi right? Does the 6758 spool faster than the k04?You may get reliable or you may not. So far mine has been but the stock pistons on these cars are a bit of a crap shoot.
I haven't had mine on the dyno but the MAF reads 44lbs/min at 6400 rpm so I am probably in the neighborhood of 400 to the wheels. I run an EFR6758 at 27-28psi on E47 and methanol injection. I also have the Werks intercooler and high flow cat.
My theory is that the methanol is important for the durability of the pistons in keeping the combustion temps down. E47 helps with this as well. My intake temps are the same at idle as they are at 27psi and the end of a third gear pull.
Mine is a daily driver. No issues so far.
That's pretty much it. You don't need the intake and charge pipes to make the power. I have them but they are just for aesthetics.Anything else under there? The 3 bars are good for 29psi right? Does the 6758 spool faster than the k04?
I have been collecting info for a few weeks and here is my current blueprint (subject to change):
-Either upgraded k04 or EFR6758
-High flow cat
-Cold air intake and charge pipes
Larger turbo/more boost (EFR7163) and higher redline. Built bottom end, stiffer valve springs, neutral balance shafts (or none), etc. You could drop the compression a little to facilitate additional boost but that would probably require a full custom piston. I don't know if there's anything off the shelf that will do that.I heard some of us are running 500-600HP with the lnf, what are they doing?
Mine didn't survive... ended up buying a new engine and am installing pistons and rods in it.Everything I've read so far from just about everywhere says that the stock bottom end is good for 400-450 and needs to be built if exceeded. Is that not true?
I don't mind spending some money but I dont want to exceed 4-5k
That is not a stock engine - it has special connecting rods and forged pistons. So that is $4K before you do anything at all to add power.
