N249 Bypass guide LCR

[Crhome]

1 word OMG, I just done this tonight and I still can't believe the difference it made. It was simple to do. She is holding boost much longer and I don't know if its just me but also pulling harder. Thank you so much for the guide.

so any hose you disconnect, what ever you disconnect it from you dont block/cover it even though nothing will be there anymore? it just stays open?sounds a bit dodgy thats all

 

[LEE69]

Yes, because you are bypassing it

 

[karlcuprar]

but surely you should close the open ends off now its not connected to anything?

 

[LEE69]

Why if it is bypassed?

 

[karlcuprar]

because theyre not in use anymore are they?

 

[LEE69]

So if they are not in use, they don't need "capping"

 

[karlcuprar]

so if i disconnect a hose and take that hose to somewhere else i just leave it open? thats all im asking because im going to do it

 

[LEE69]

Yeah the LCR is dead simple just follow the guide and you'll be fine.

but surely you should close the open ends off now its not connected to anything?

I can't say for sure because I have not blocked them off but people have had bad effects after blocking them off and even worse when it's disconnected...have search mate a lot of threads do a really good job of explaining it

i done it then and the only difference i can determine is that my forge split-r valve makes more of a flutter chatter kind of noise instead of just a pssht! the dump definitely kicks in quicker off throttle lift off though, however i dont know if its me being paranoid or not but my max boost is about 0.85bar and now holds at 0.7 dont know if thats what it used to do or not though

 

[karlcuprar]

anyone?

 

[LEE69]

Sounds like you got a boost leak, yuk a spit r

 

[karlcuprar]

its definitely not a boost leak and its personal preference

 

[vagman2001]

its definitely not a boost leak and its personal preference

Have you done a smoke test? You won't always hear one! Leaky split r?

 

[LEE69]

but my max boost is about 0.85bar

0.85 bar = 12.3 psi
Standard lcr is 14 psi, again, you might have a boost leak.

 

[LEE69]

Try a standard recirculating valve if you can, see if the boost holds better

Sorry to be ignorant, but this thread is now 11 pages long, what will I gain by doing this bypass?

Nothing at all. At least, I didn't.

Before doing this, does everyone recommend NOT doing this bypass on the stock dump valve?
