Hi

MY00 uk, 440s at 86% idc, running 1.35 bar. I will be fitting a front mount and induction kit soon. Will i need to replace the 440s for 550s?

Cheers

 

assuming that is on standard turbo then you should be okay, once remapped obviously.

The turbo is a td05 16g

Are you running a Pump and Reg.
IDC seems low at 1.35bar.

I was hitting 97% but now 100% since a filter change. But it is a bit on the rich side and at standard pressure.

 

Hi
walbro pump only

As Scott says the IDC is low for that boost on a TD05 16g.. would be concerned it is lean..

or is the boost profiled so it only peaks at 1.35bar and tails off? not sure why it would be setup like that though with IDC still available.

Simon

 

It was mapped to 1.35 peak tails off to 1.2. No nock/det and had at least 6 runs on the rollers.

 

the tailing off would explain the IDC then.

so in answer to your original question.. you would benefit from 550s whcih would allow it to mapped to run more boost and held should you want more out of it.. which of course you do else you wouldn't be fitting the FMIC.. lol

You could use an adjustable fuel pressure regulator instead (or as well) as the 550s.

Simon

 

Ok thanks, how much boost on standard internals?

Cheers

 

Depends on your mappers views.

1.4bar is fine..

Simon

 

Mine tails to about 1.1/1.2bar from 1.35, so I still think the duty is a bit low.
They do tend to run richer on the roller though, hence why it may not of been picked up.

Do you know what boost it achieved on the rollers, as this also can be slightly lower then on-road.

 

Produced 1.35 on the rollers but sometimes gets to 1.4 on the boost gauge when on the road. I thought that was down to the cold/colder mornings.

 

I managed to hit 91% idc on a 20G @ 1.61 bar so id say that it would be wise to get 550s
