BOV fluttering back though POD, Heat issues

Hi

Once again in the search of power I am wanting to do something about my intake. When feeling over the bonnet, right above the POD is feeling like the hottest part of the bonnet. I'm guessing this is because when the air is returning back through the compressor its picking up all that turbo heat & throwing it back out through the POD.

My question is how do get the temp down. I was thinking of a Cold Air Box & some additional piping bringing cold air up into the box from the bottom of the car. I'm at work now & have not yet had a good look @ how this is going to work / fit.

Anyone who has had this problem & or how they solved it would be great. Are there pre-made cold air boxes for sale for the r33 gtst & any comments from people who have had experience with them

I currently run a t3/t4 HiFlow Turbo with a K&N Pod.

Cheers,

You can buy a could air induction box from www.nismo.com.au then simply get some ducting pipe and make a duct from your front bar to the box, wella, heat issues solved. Also, is your turbo in the stock position? And does it have the stock head shield over it.

Oww ok thanx, Hmmm $200 or $300 for carbonfibre? I'd rather something a bit cheaper full stop, custom made maybe.

My turbo is in stock position & as for head shield i dont know.... I can see the turbo, nothing covering it, is that what you mean?

Its hot not because of reversion but because you have a pod that is sucking in hot air from the engine bay. As suggested above a CIA will help your cause.

Technically reversion would keep your engine cooler due to overfuelling on release of the throttle body. It would be only a few degrees and for a few seconds though, but has nothing to do with a atmo BOV. Plumb back BOV I beleive increase intake temps, due to re-circulation but I have no evidence to support this.

do you have a Frount mounted intercooler?

if not, you will not be able to feed cold air from the bottom due to the fact that the stock cooler is there..

If you want to do something cheap, go to Clarks rubber and ask for some of that Shielded rubber/foam stuff.

then go home, get some cardboard and get in your engine bay and try to cut out a partition that would go between the angine and the pod filter.

get it perfect, then cut that shape out of the shielded rubber stuff.

when you place the new created shield, make sure the silver shielded stuff FACES the engine bay and the rubber/foam stuff faces the pod filter.

this will help a little and only cost you about $20 for a whole sheet of the rubber stuff.

cool.

you have a fmic.

so the stock cooler place is perfect for a cold air duct.

go to a plumbing store and buy 3 inch PVC piping.. get about a meter.

also buy 2 x 90 degree bends and 2 x 45 degree bends.

also get that blue plumbers glue.

now go home, cut a 3 inch hole in the panel under the pod filter, and design a cold air duct with the pipes you got so that it goes from the front bar up to the hole under the pod.

this wouldn't cost you any more than about $20.

buy some Matt black spray paint too so that once you have measured and cut the PVC piping for the CAI, and you have trial fitted it perfectly as you want it, Glue it together and then once dry, paint the thing black so that it can't be seen too easily..

NOTE. the bends that I told you to buy are great.

Once you have those and the straight pipes all together, it all fits together like lego. and it is a perfect 3 inches and smooth on the inside for better air flow. unlike those air con ducts that people use.. that flexible slinky type stuff is crap.

Hi GTST,

Did u ever have any dramas with your cai kit picking up water when it rains? We had a simular setup on my dads r33 and whenever it rained the ic would fill up with water! We were considering putting a drain plug on one of the ic end tanks!

Thats what happens when you use a 'everybody look at me' bov on ur car :D

??? the intercooler was filling up with water?

so you're saying, the water was going up the cold air duct pipe, somehow through the air filter, through the turbo and in to the intercooler?

that's pretty much impossible..

or are we getting our wires crossed.

you said...

I read "IC" as InterCooler

please explain..

GTST,

Thats what appeared to be happening, the air filter is an apexi super suction kit. I should add that this only happened on the highway at 100kph in consistant rain fall.

It's not so hard to believe, the air filter has a really high flow so water can get through it. With the turbo sucking in air it will pull the water through, it'll have no trouble going through the turbo and then collects in the ic because of the resticting tubes + gravity would play a part.

The 1st time i noticed it we were on our way to the dyno and it was raining. When the car was doing runs on the rollers i could see a vapour shooting out of the tb, i had a look and noticed one of the vacume lines had come off and when the car was at full song the water was being pushed up out of the cooler and shooting out through the hole!

There wasn't much water in there, a couple of power runs pretty much got rid of it all out of the hole but its something to think about.

      Thanks for the quick replies guys its appreciated. A small extension was welded onto the standard 6boost external gate pipe which you can see where the pipe goes from black to stainless just below and to the right of the rear housing in the first picture. Overall I would say the flow is pretty good other than 6boosts choice to come straight off the collector at a decent angle.. Not sure why I went with two valves, I originally replaced the stock twin bovs with the GFB when I had the twins on. When I purchased the EFR it came with the Turbosmart Kompact BOV so I figured that would be a better option than the stock EFR Bov. I don't believe the Turbosmart BOV is adjustable? When I get the spike and then sudden dip in boost pressure, the turbo speed does drop as well. Stock head size wise however I believe it has Neo Turbo springs and a Neo Turbo intake camshaft and an aftermarket exhaust camshaft in the vicinity of 260 degrees. We didn't try a different MAC valve, we tried two different ways of plumbing it and we also tried removing the mac valve entirely and just having the boost source from the turbo directly connected to the wastegate and it still spiked / dropped and exhibited the same behaviour. Standard R33 GTR 5 speed tansmission. I'm running a Haltech Elite 2500 and can provide some logs if you. I understand what you're saying in that it looks like an auto plot however no, it's still a manual and it just has a lot of torque down low, for all intents and purposes it's a very impressive street car. I've attached a photo of the quickbitz dyno plot which was when the only difference is I was running -5 twin turbos with a mac valve. As you can see theres a decent dip in AFRs between 125kmh and 135kmh. Our problem now is not that the AFRs are dropping, just the boost pressure is dropping, however it is evident in the same RPM range of the map, coincidentally or not.

      What transmission are you running?  It's a bit tricky with the scaling, but at face value the power "curve" looks more like a "line" which is a bit odd... basically a lot more like a dyno plot I'd expect with a highish (compared to a factory auto) stall torque converter type setup. If this is running an auto then this kind of boost control challenge is definitely a thing, the rpm scale on the dyno doesn't reflect what the engine is actually doing (unless the dyno has access to the engine's ACTUAL speed electronically) and what you'll get is a big rpm flare up as the engine torque launches past the converter pump's ability to resist torque at that rpm, then as the converter starts picking up rpm it will kinda even out again and the engine rpm will pick up more steadily. The trick with this "flare up" is if it's kinda near the boost threshold for the turbo then the engine's airflow requirements to maintain the previous boost level will outrun the turbo's ability to supply that boost - so you end up with a natural flattening off, if not dip when that happens.   If you are running closed loop, or even tune the "feed forward" wastegate duty cycle to deal with that rpm spike then when the engine starts settling to a more typical climb you'll actually have a situation where the gate is "too closed" and boost will run away for a bit, then have to pull down again.      It's not trivial to get this perfect as most boost control systems are generally expecting more predictable engine rpm rates of change, but if you *know* that's whats going on then you can at least "accept your fate" and realise getting that area perfect is kinda chasing your tail a bit, and assume that if the rest is working sensibly and the spike/dip isn't completely uncontrolled then you should be good. Sorry if I've gone off on a tangent, but the dyno plot and boost control behaviour look a LOT like what I've seen tuning autos in the past. What ECU are you running? Could possibly be convinced into looking at logs if I get too bored this weekend haha.

      A few things that seem a bit off here. - why is there 2 BOV’s?  - the turbo smart BOV on the compressor housing, is it turned up ALL the way? I have seen this become an issue on old man Pete’s car. It would push open and recirc, turbo speed would rise and the boost pressure would do weird things. - stock head? Does that include springs? - tried a different MAC valve? Is it plumbed correctly?
