Hi all,
I am running a standard set up at mo,the last owner set the boost at 14 PSI / 0.9 bar,i have seen various figures being banded around the forum so I thought I would ask the quessie and hope for a safe answer from someone who knows there stuff lol. First off what kinda difference would it make if i tweaked it up a bit?? Second off, is it SAFE to do so?? It has an adjustable controller on so easy to do. Thanks in advance! Jim

 

Thats pretty much standard boost, safe (depending on any mods) is probably around the 1.2bar mark, but its also advisable to run a knock sensor of some sort (KS3/4 or a knocklink).

my 2000 classic runs 0.5 bar i presume that this is standard??

 

No mate, for some reason your car is running in safe mode. You'll have to do an search on here about reading fault codes from your ecu.

uk classic is .8 .9 safe is 1.1.1.15 fuel cuts in at 1.21 i ran at 1.1 for well over a yr befor remap

 

would a avcr bypass fuel cut ? also my rac rouns 11psi no worries just brought a avcr hoping to push the psi up a little

 

so if i were to tweak her up to 16 psi would it make any real difference to 0-60 performance???

 

Safe mode eh? ****! Sounds expensive so just to clarify what is standard boost on a uk turbo? I think the lambda sensor may be fooked could this be the culprit?

 

From .9 to 1.1 it's around 25-30 bhp would have to check my print out, uk turbo is .8-.9 as said in other post.

 

Ahh right I'd best get it booked in sumwhere then. What usually causes this problem sorry to hijack the thread and all

 

my uk 1999 runs at 1.0 bar std

 

How do you adjust the boost?

 

map tweak? boost controller?

i ran 1.2 bar on mine with, hks induction kit, 2.5 turbo back magnex, a HKS fuel cut defencer and a HKS air fuel ratio adjuster, and to be fair it was quite rapid!

 

So are we saying that 1.1 bar / 16 psi is perfectly safe? Thanks

 

no no no no!

don;t just tweek it up a bit, you'll throw a piston out the side of the engine. mate's lad bought a car, was very quick. had a manual boost controller on it. he put it on the dyno the day he got it to make sure all was running right. it wasn't. the operator did half a run and refused to run it again untill it was sorted because of how dangerous the AFR's were.
Boost/fuel cuts are there to protect the engine, removing them is a bit like being on top of a tall building and removing the handrail around the edge of it.

only safe way to up the boost is map it, simle as. the mapper will push the car as far as he/she sees safe to do so. some cars take more boost and timing than others.

get it mapped properly or you'll be asking 'where can i get my engine rebuilt'

 

It makes sense when you think about it more boost= more air/fuel etc

 

yep, looks like for the origional post its a manual boost controller being talked about

 

Well thats it then!! Stick to a safe 0.9 BAR / 14 PSI. Question answered,topic over,proper remap for me I thinks lol

 

good choice lol
