1.2 bar

Hi all,

would it be safe to up the boost to 1.2bar on a fcd and fpr aswell as getting it checked out on the rollers ?

Im currently on 1bar on my hybrid at the moment but looking for more power.

I would like a ecu but im tight on cash at the moment.

Not advised really mate, especially with no management. A friend of mine ran his with a hybrid ad just adjusted his fpr to suite the boost, it was all wel and good for around 4 5 month. Then one day it just didnt start. And the car got sold between 3 or 4 different owners. None of them figured out the problem.

to be honest as long as it doesnt lean out at any point under load and its safe across the whole rpm/boost range then it shouldnt be a problem.

if you take it to the rollers and they have any concerns then thats the time to keep it to 1 bar.

45 months seems decent lol

Its not advised as the fpr cant adjust the fueling at individual revs where as the piggy back /stand alone can.
1bar is usally the peak of the CT9 but i dont know about hybrids.But if your on stock internals i highly doubt you can map it safe at 1.2 without detonation resluting in your internals being,for lack of a better word, fucked.

Forged will stand up to the det much better but it is not a sure way around it.

As for the above with the car not starting,more info and im sure it could be figured out in a different thread.

4 - 5 lol, and internalls will be alright with 1.2bar from a ct9, theyr only crappy little turbos anyway they pack up after a few weeks at 1.0bar. Oil seals are the main concern with them.

I think it was the battery :p

ran mine for ages on 1.2 bar using an rrfpr / FCD. setup. first with a ct9, then a hybrid. made good power, no failures. as long as it's setup right.

just cos it's crude doesn't mean it's not effective ;)

Its effective yup,but it could end up with a lack of compression :D
It depends on who checks and adjusts your fueling and if your engine takes well to it,no?

LMAO,why do most run a 1bar then?
Its harder to get it mapped safely the more boost is used.

people only run around 1 bar on std ct9s because any higher & its out of its efficiency range, more boost shouldnt mean its harder to map, it depends how controlled/stable it is. Eric (ktl) you just spent all that money forging your 4E now you wanna skimp on one of the most important mods which will give you reliablity & power, you could run it on a fcd, rrfpr but at least get yourself a emanage blue. :slap::p

that had nothing to do with it, :homer:

EDIT: obviously there are better options out there, his question was would it be safe, and in my experience, it was. my hybrid was a fair bit bigger than most, and aside from a rich idle (which i still suffer with, trying to fix still) i had no problems

If ya wanna run 1.2 bar safely with a fcd and rrfpr, you wanna get some sort of fuel controller to trim fuel where required checked with wideband!

You can do it with jus' a fcd and rrfpr, but somewhere in the rev range (coming onto positive pressure) the fuellin' will be too rich or even lean out. Does not mean you can't still tune it with jus' the fcd and rrfpr, it's jus' gonna take the tuner more time to get the safe a/f target so you can have a reliable car.

not right.

just get her fuelling right and she'll be grand, 1bar/1.2bar.

if the AFR rights and you dont have the dizzy somewhere stupid there shouldnt be a problem, have a listen for det if you want, only downside will be if she is fuelling right up top she'll be rich down low.

So then mapping it at 2bar is the same without having det?
He never said it was forged though so the internals will stand up to it much better.
I was talking about internals,not the turbo blowing:)

If it wasnt mapped right on stock internals at a much higher boost than stock then i think it would,in the end,go bang.

But seeing as its forged it should handle it well enough but it wont stop it from eventually blowing if its not mapped right.

But can you get it fueling right at double the original boost with just an fpr and fcd all the time?
It would depend on what the fueling shows up like on the map no?

yes you can get it fuelling right, but like dubseven and others have said whats bang on up top will be rich down low with this style of setup.

and what map? we are talking about a fcd fpr.

You could still get the likes of martin tracey to adjust it and check your fueling at the same time,he does do it:)
