Whats the standard boost on a LCR 225?

Just wondering. I have since remapped mine and fitted boost gauge and was wondering how much more boost I have over standard.

Boost peaks at approx 1.8 bar now.

I thought a mapped LCR was more like 1.6bar / 22psi or there abouts :confused: 1.8bar / 26psi does sound a bit much! :hide:

My 210 LCR, when it was and is standard, peaks at approx 10-12psi and when it had an AMD map it peaked at 22psi

Yeh, 1.8 for bout half a second? then sitting about 1.6 bar tops?

Yes, that's about right, falling to 1.1 at the redline. Peak power is usually at 5,500 where you should see a smidge under 1.2 bar.

And yes, standard boost is 0.8 bar.

I can believe it'll spike to 26PSI, but I don't think the standard turbo, even with 4bar FPR can sustain 26PSI... that'd be a very nice pull, if possible.

Over-optimistic boost gauge? :p

any stage 1 remaps use the 4 bar fpr?

Not as far as I know.

I'm a bit confused by your question though...

Edit: oh, I get you now. It says 4 bar fpr in his sig. @OP - you should take that off, probably an idea to read up on A/F logging just to be sure, but nobody does a Generic Stage 1 map that needs a 4 bar fpr AFAIK.

And, At lickwid, fuel pressure reg won't make a difference to boost pressure. 1.6-1.8 spike is "fine". people will say otherwise and suck their teeth, but it's what all LCR's do (if you take into account that his boost gauge might be a bit out).

All the 210/225's "saturate" the MAP sensor, which according to many, is a REALLY bad thing :shrug: As I understand it though, when it's runnign above the MAP's maximum, it falls back to using the IAT and the MAF to calculate the boost. Probably explains why a duff MAF on a chipped motor is extremely noticeable...

Yes exactly where I was going with this Phil.....

Blelock - I fitted a 4bar FPR to a stage 1 LCR Running Revo on the advice of a tuner (luckily they are no longer solvent) the upshot was fuel economy was really bad, massive overfuelling and reduced power (about 10-15bhp down at a guess) if you are running a 4bar FPR on stage 1 remap follow Phil's advice above and do some logging yourself......or speak to an independent tuner etc

mine is around 1.5-1.6 bar,i was told any more and it wouldnt be reliable,didnt know if that meant turbo would fail or it would over boost and then ecu cut boost back to protect engine.
