Recirculating Bov Aftermarket Turbo Intake

[Marcus89]

I am just finishing up an install of a hypergear ATR43 turbo into my car am going to get an aftermarket intake as the factory won't fit straight in as well as the issues of it sucking shut at higher boost.

I was just curious as to how people have going about fitting the reciruclating pipe from the BOV to their new intake? Get it custom made so there is a place for the pipe to fit? Or get rid of the factory metal bracket/piping and run the BOV piping back through at another place?

Hoping to get car back on the road ASAP so if anyone in Brisbane has had a pipe made up I'd love to know where at and how much it cost.

Either way is easy. On my old setup I just cut the factory hard pipe to suit and used that, but I was using a GTR bov so the hard pipe worked as a reducer. If you're using the factory bov then you can just replace the whole hard pipe with some hose.

Personally I think it is easier to just cut the hard pipe to suit, large ID hoses have a tendency to kink and make routing them a bit messy etc.

go to exhaust shop and get them to weld one up. Or check with M35 scotty or Abe on this forum.

Or get a aftermarket BOV, then run 4inch metal induction pipe with a 4inch 45 degrees silicon hose.

I also own an atr43g3. I bought a 4in 30cm bit of aluminium pipe, 4in 45 degree elbow, couple clamps for under $80 off ebay (uk). Then get someone to weld a couple fittings onto the pipe for the bov and pcv hoses to go on. Do you have the intercooler side sorted?

[Marcus89]

Awesome thanks for the advice. The intercooler I will be able to sort fairly easily almost had it all setup with just the factory piping and a 45 degree pipe off the turbo just needs a little extra length so will likely get a short piece of aluminium for that.

I didn't even think about cutting up the hardpipe no idea why will likely do that. Time to get myself some piping will likely ring around a few shops and see what they can supply at a reasonable price don't want to wait for shipping if I can help it

I have just gone thru this myself, i got a 45degree bend of 4inch pipe which i cut to the right length then got a 4inch to 3inch reducer and connected the airflow and pod, cost me about $60 for the pipe

i then got the fabrication shop to weld in a short pipe and then just connect as stock , grind off the blow by pipe and decide whats doing with that after or get another short bit welded in too .

problem now is i think the fuel mixtures are way off as in very lean, cause the idle and running is very rough and needs tuning,

[Marcus89]

Mines a ATR43G2 so I only need a 3 inch pipe anyway makes my life a little easier in regards to connecting up to AFM at least I believe it is 3inch gotta double check measurment. Going to see if I can fit my pod into a customised factory airbox if that seems too much work will likely just get ebay spec perspex box to make up.

What could of caused the terrible idle mixtures? Doesn't sound right to me

Interestingly found these photos

Which are from a hypergear car I believe (photos same as the atr43 install thread that I have read a couple times) Using the stock airbox although the AFM is moved. I could do this and not run a pod although I do like the induction noise. Maybe temporarily I will keep the airbox and see how it sounds

More trouble than it's worth.

Now I'm confused about what you are trying to do?

Talk to Scotty the link is below in my sig

He can sort out a pipe with all fittings you need for a great price

Do it

I could be wrong, but having a bigger intake pipe than normal , i think it fools the air flow, maybe the air is travelling at a different speed than the smaller stock pipe,

i have tried adjusting my power fc , the injection correction and that made it idle alot better so increased correction makes it richer ( from 1.0 to 1.3) which must mean a bigger intake is making the tune leaner. correct me if im wrong??

It shouldn't be, the AFM will still be registering the air going in. Also your engine can only swallow so much air at idle. Unless your stock intake pipe was a restriction, which it wouldn't have been, then it won't be using any more at idle with a 4" intake compared to a 2.5" intake. Or so I understand it.

Doesn't sound right to me, I had no problems with changing my intake pipe without a tune. Did you change anything else, ie. blocked PCV or bov or anything like that?

no i have stock blow off valve recirculating, ive checked and replaced clamps and hoses, i think it really happened after the tomei cams were put in,

Its all a bit of a mess at moment until it gets tuned, but adjusting this injecter correction makes it idle alot stronger, one the original tune setting the motor just shakes like its got massive cams , like a drag car,

If you think about it, the size of the air flow is what, 3inch? and the intake is 4inch and big 4inch comp with gt30, its like twice as big as stock, thats got to do somting to the air flow

maybe a 3inch pipe is close enough, but 4inch must mess it up , like speed or mass of air after the air flow would be different?

The total size of the pipe has nothing to do with it, your engine only flows so much air at idle. It's the engine drawing air through the pipes, not the pipes forcing air into the engine. Until you get on boost obviously, which is when size matters.

I'd say it is your cams, not your intake pipe.

ok then well thats a good thing that they are making that much difference then, i need to drive it to the tuner 40mins, should i richen it up a fair bit to be safe? i got from 1.000 upto to 1.300 and it sounded heaps better, would this richen up the whole fuel map on a power fc ?

Been behaving like a dam drag car, lol, the times ive driven it people think im about to do a 100meter burn out lol,

[Hanaldo]

Hard to say if it's safe to drive. The intake pipe won't make a difference, but if you have another issue then it might still be dangerous.

I'm running a hyper gear atr43 ss1, with a recirculating bov and am in Brisbane if you still want to see one setup. Or I can post a photo.
