I just installed a Trust Airinx on the weekend, and right now I'm considering taking it off. Does anyone else have one? It has to be the loudest piece of **** I've put in my car. Are they supposed to sound like an extra loud vacuum cleaner on intake and a horse when you let go of the throttle? I expected a little bit of extra noise, but this is ridiculous.

I was going to record a sample of it and put the MP3 of it up, but I just thought I'd check first. Maybe I've screwed up the installation.

I'm going to make an insulated box to go around it quiten it a bit (and hopefully only let in cold air). Will this make much of a difference?

As an aside, anyone who reckons a pod filter is a good substitute for the BOV noise is kidding themselves. It sounds terrible, nothing like the clean tccchhh sound of a BOV.

Cheers,

Michael

Yes it is supposed to be loud and if you get that "Horse" sound then your bov is not working efficiently enough.

Trust make a good filter but unfortunately it always comes last in filter tests with k&n first and HKS,blitz and apexi in close succsession.

If you have the option to get rid of it and get the apexi then do it.

Thanks for the responses guys.

Boostmeister:

The whole reason I bought it was based on a magazine comparison. It had equal best filtration and the best performance. I'll have to find the mag it was in.

Now, about the BOV not working efficiently enough, I've got the stock one. I thought that was good for a fair bit above the stock power. I don't think I'm too much above stock power levels, in fact I'm still running 7 psi boost. I used to have a Blitz atmo one in series with the stock BOV, but that went when I put the FMIC on. So do you think my stocker is faulty? I'll replace it anyway as I miss my BOV noise :)

I'll have a look for you. No promises though. It was a pretty good article actually. Otherwise I wouldn't have bought the pod on their recommendation. I reckon that since it's as loud as it is, it has to have good airflow (ie good performance) but the filtration would be down. The article didn't agree with that though, as it said it had good filtration.

I also think that it would be good if there was only one company that evaluated all the performance parts.

Yeah I'll check them out. The article I read may have even been from there. Not sure though.

I remember one thing the article said though, the reason they liked the Trust was because it was a dry filter, which meant it wouldn't foul the AFM with oil like many of the other ones can do.

Black33,

The article I read said it filtered very well, and since it was a dry filter, it wouldn't get oil on your AFM. It certainly isn't a BAD filter. I think all the filters mentioned are all the best of the best, so it isn't like you're tying a handkerchief over the inlet pipe or anything.

    • Ok i will get those 310mm. I found one but on a different site. This is the description on those...is it ok? Technical parameters: - Axle: front. - Disc type: ventilated. - Number of holes: 5. - Disc diameter: 310mm. - Total height with center: 54mm. - Thickness (new/min.): 30/28mm. - Designed for brake calipers manufacturer: Sumitomo.
    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
