What Have You Done To Your Stagea Lately?

[iamhe77]

Whats wrong with your 3 dials? My boost gauge isn't working, but I found a thread on Scotty's soldering fix, so I'll do that, get it working, then think about changing it

Iain has an RX, so no dials from factory.

[iamhe77]

when I got my suction pipe made by scott it increases airflow dramatically.

I think Cam experienced it too.

as well as scott jethro craig etc.

our Air flow signal cuts the engine when it reaches 4.80volts through the air flow meter(correct if a different figure)

You'll need to get it tune, and have the airflow clamped to get it to stop doing it. with an emanage etc.

mine has a 3inch pipe custom made from the turbo outlet to the airbox. if your doing that, I guarantee you'll hit an airflow cut.. just be ready for it!

Edit: and yeh stock injectors will max out with the suction pipe mod, which isnt very safe!

Yep, still experience it when I put the foot down due to still running the stock ECU (nor for long though )

awesome! what you thinking? if you dont mind.

[bigkevracer]

Bah! Can I upgrade the injectors without running an emanage or upgraded fuel pump?

[Sunkist]

you can probably to a Tiny extent, but anything safe? you would want to be running an emanage.

stock fuel pump maxes out at 220ish kw with higher flowing injectors..

[richzx]

What about with the stock snail, does the suction pipe still max out the AFM etc or is it only with a hi flow turbo that this happens?

[Sunkist]

yeh it does.

I think Cams is currently a stockish size. and when mine was a stock size it was doing it..

[Daleo]

yeh it does.

Cam was one of the first Hiflows, IIRC, it just a mystery bag spec wise; might not be maxed as easily by a stock turbo?

[iamhe77]

Yep, my turbo is very close to stock size it would seem.

Look forward to seeing how early it comes on with a tune

Suction pipe eliminates the air supply restriction caused by the stock intake piping to the turbo.

Unfortunately opening this out allows too much airflow under full throttle for the standard ECU fuel system.

It may not do it with an upgraded fuel system though.

as cam said stockish size..

im pretty sure his one cuts at something like 4,500 right cam?

its not hard at all to get to 4,500

[bigkevracer]

So... the long term solution is obviously injectors, fuel pump and emanage.

What's the short term solution? Take it off (which I'm sure will be a pain in the arse!)?

[Sunkist]

well you can drive it around as normal. i think the airflow cut will be saving your engine from running TOO lean in the top end where the injectors are maxed.

but you will experience an air flow cut.

put it all back on when you go for a tune and emanage install! with injectors pump spacer(depending on brand of injectors you might need a plenum spacer) etc..

all my stuff was sitting in my room until i wanted to tune!

EDIT: this is what I mean about the Domino effect!

You were going well for a little while there Aaron, but quite wrong here.

Mine doesn't run out of puff at all.

Prior to the suction pipe, I could boost right up to the limiter without running out of puff.

what? lol

no i meant your turbo is a stockish size, but it didnt mean that it wont cut with a larger suction pipe.

When you put the suction pipe on, didnt your start cutting in the 4k RPM range?

my first turbo rebuild was a stock size inducer, with a slightly larger exducer - but it would still cut.

[ironpaw]

Once you install the suction pipe you'll get airflow cut. This happened with me and that's with the stock turbo, at around 4k RPM

I timed it so that after I got the suction pipe, I had Scott's hi flow and injectors installed the next week, then off to tune on the Saturday.

You'd also have to baby the car till its tuned (this is if you upgrade the injectors and what not)...I got sick of staying off boost pretty quick!

Depending on the size of injector you're upgrading to, you won't be able to drive it unless you've got a basic map put in via a piggyback. My car was at Scotts for a few days getting all the mods put in and when it was ready to go Cihan came to install emanage and loaded a basic map into it so I can drive it...

I think Aaron is saying after you had the suction pipe fitted you had airflow cut @ 4.5k RPM too?

[Sunkist]

no. i called him and explained what I meant.

It doesnt happen at specific revs.

it was just around where it happened...

It happens once your AFM receives and sends 4.8v+ to the ecu, from the increased air flow.

[richzx]

So the suction pipe doesn't max the injectors just the AFM? If that's the case wouldn't a fuel cut defender fix that by clamping at say 4.6V? If the injectors are maxed then obviously needs bigger injectors.

Surely you'll start leaning out the fuel mix REAL fast if youre doing it that way?

[Sunkist]

mine were maxing before it cut.

so my informeter told me anyway.

so i was forced to baby the car around lol

emanage can clamp the aiflow at 4.6 as mine is.. anything after that is mapped by a boost sensor plugged into the emanage.
