Hey people, just installed a Apexi power intake POD on my R34 GTT (stock) and it seems that on the factory boost gauage, it has a significantly lower maxium boost reading (previously read like 0.75, closer to 1+ but now it reads 0.5 on the boost guage). Strange the car is much louder and i dont think i can tell any difference in power loss, not sure. Could it be that the POD is sucking in hot air and loosing boost that way? its not boxed up yet but will be. What else you guys think it could be?

dont quote me on it but ive heard the factory boost gauges arent the most acurate, best to get an aftermarket one.. I doubt the pod filter would be reducing your boost and if you cant notice any drop in power id say its just your gauge reading wrong.. It could howver be that the pod filter is too small and cant suck enough air in but then im sure you would notice that

Take it off and check to see if there is anything in the pipe.

Who did the installation?You or a mechanic?

I have heard some horror stories about rags getting sucked into the turbo and blocking the inter-cooler.

Not that this is whats happened....just trying to help....gauges just don't go when you install a pod filter.

Yeh its kinda wierd, the boost does sit lower on the guage now, it was done by an import garage and it was an apexi made for the car.. Im just wondering without the POD being boxed up it might be sucking in much hotter air, could that lead to a drop in boost pressure?

Have you noticed this under load ? The 34 like the 33 is limited to .5 bar until you hit 3500rpm. Goto fourth and kick back to third, then double check that it hits .7 bar. Generally speaking the 34 factory boost gauge is fairly accurate, when it does begin to play up you get an all or nothing reading. I've had a autometer boost gauge, blitz electronic boost gauge, and the factory boost gauge and they all are pretty accurate. Stan (satanic) also runs three boost gauges and finds the factory one pretty close to the mark on the 34's.

Also do a hard ecu reset in case it's your AFM playing up.

Yea it does stay just above the 0.5 mark all the way to the red line.. the ecu has been reset aswell since the install

      Duncan's V37.......race car?

      By Duncan · Posted

      Small update for the day... Turns out the intercooler and engine coolant hose kits are anything but complete....I probably should have counted better but it only really covers about half the coolant hoses in the car, it really just covers the visible stuff and pretends everything else doesn't exist (turbo water feed and returns and also heat exchanger lines through the 2 pumps and cooler) .In any case, I'm happier to have half reliable hoses than none, but a bit of a disappointment. Anyway...finger click (and 5 hours).....hoses in place, lots of spring clamps replaced with screw clamps, and engine coolant is on the pressure tester for the night.   Incidentally, upsized header tank is an Inifiniti factory option....not sure I'll ever do prod car racing in this but at least it is legal.

      Just weld it onto the hot pipe. If you want it right after the turbo, put it right after the turbo. Or rip the comp cover off and drill and tap a hole into it.

      hahaha glad I can rely on you two to go on a spiral at the drop of a problem! Some quick answers....the ducting is excellent top bottom and sides....everything that gets in goes through the coolers (noting the oil cooler redirects it out again, fair call if it is cooling 120o+) and the heat exchanger for the intercooler also has some scoops to pick up more than it's fair share too. I can't see going down the water spray track....no bueno for formal racing and a big risk for long rally days if you run out (plus I'm not clear if it is allowed there either yet).   Frankly, it must be possible to reliably put 400kw through a standard front end, the BMWs do it so I just need to work it out....I'm starting with reducing blockages in the way and adding some coolant capacity with a bigger header tank, flushing rad and making sure it was filled/bled properly (I didn't do the last coolant change); also taken measurements incase next step is a bigger/higher capacity custom radiator

      R32 GTR Limp Mode?

      wow, a completely stock GTR! I've got to admit, I have no idea from what you are describing....do you have  any idea where the "thump" comes from, and are you certain it is the HICAS light not something else like the cat overheat light?

      nice work, welcome to the world of CAD! fabricating accurately in 3 dimensional space is beyond me....I almost always end up making something more than once...sorry I mean I extensively use prototyping
