VTT Inlet Review

[DR-JEKL]

Hmm yeah it's surprising that it's taken as long as it has for the platform to realise the potential these inlets offer in terms of increased power and essentially increasing turbo efficiency and perhaps prolonging the turbo life also

So with the AFE DCI setup, did you notice a lot more intake noise after the inlets were fitted? Or is this still a works in progress and you've got the rear pipe left to fit?

Jeez where you cut that pipe really shows how restricted it is!

I'm using stock/Dinan airbox Shane

Hilarious isn't it. I feel sorry for those turbos.

wow kinda amazing so much power was sucked through such a tiny straw.

you look at the outside and think it's not too bad, until... wall thickness.

the way it's happened is funnier, people 'testing' the changes, concluding they don't actually work.. then going 'oh shit my bad' later lol.

[martymil]

The thing with inlets is not so much increase in power but how hard they have to work to make that power, its all about wgdc and heat.

If we can lower the wgdc the heat will lower too as the turbos don't have to work so
hard, with lower heat more power and longer lasting turbos.

If I can make 10 rwk out of inlets i'll be very happy but I'll doubt it.

What ever the outcome I'll be posting the results with logs before and after.

The only problem is that the results aren't going to be just an inlet change as dp
will be in there too, as I'm still running the factory downpipes making 311rwk.

At 311rwk the factory clutch cant handle the power for long and starts to slip and I'm fitting a lighter flywheel and clutch which will effect the final result too.

So the test results aren't going to be really be able to be compared but it will give an indication of what was happening before and after and what can be achieved.

Sorry dude, my next paragraph was meant for Marty

I may be wrong but I'm sure I read somewhere that Tony allowed for this, but could be a BS excuse... Better to be too long than too short I guess

Either that, or I got an unfinished product which they forgot to cut lol

The rear pipe should be done today so I'll let you know

That's actually not the most restrictive part

That was another pipe at advan, when I get mine cut I'll post up the most restrictive point of the pipe as its at least 30% smaller than that

[martymil]

Here are some pics

This is the most restrictive part of the pipe, bloody tiny.

There is no way of getting the rear pipe out without dropping the motor even
with the gearbox out, it isn't happening.

[martymil]

Got the car back today, you can definitely hear the diverter valves working, can't say much for full throttle yet as I have a 800km clutch break in period.

The car drives so smooth, its like a completely different car, it feels far more refined and silky smooth.

The rear inlet is a perfect fit with no kinks or bends, definitely looking forward to the
logs and seeing the wgdc at the drags.

Thanks to Billy from Advan for fitting them, absolutely perfect job.

[martymil]

Well been driving it around a little today, managed to put 100km in mostly heavy traffic.

The inlets provide very responsive and almost instant power from down low.

The car was always a little slow and hesitant to take off now its eager and willing at the
lightest touch of the throttle.

Keep you guys posted, will be tuning the car at the track next Wednesday.

Good to hear. I'm doing mine next week so keen to see if it'll hang with the target up top. Having the hotside done with inlets too.

Who is installing it ?

Was gonna do it myself but I just don't have all day to spend on the car so the boys from Hills Eurohaus are doing the work. Getting a walnut blast done too.

how much did they quote you?

[martymil]

Wont be cheap, what he is getting done is a big job.

Good 8 hrs work.

[martymil]

Well I got the car on the dyno today, and got a nice result.

Something wrong with the website and it wont let me upload any images

[martymil]

Before and after as promised

[_ink]

They are massive results on stockers! Congrats mate.

Did you get a log also?

[DR-JEKL]

Nice gains marty is it about 10kw or so in the midrange?

Yes got a log but had no usb so I'll get tomorrow.

the wgdc is down heaps, nothing like the tft kit but, but perfect for stockers.
the inlet temps took a big tumble, even though the dyno room was sitting on 39c the inlet temps on the third run where 114f or 45c

Originally Posted by DR-JEKL

Over 20 rwk midrange and 15rwk at the top.

Previous run was on 22 psi this time round it was 19psi and under

It made the best of 330rwk on 22psi but the stockers ran out of puff really quickly and fell over in the curve a lot quicker.

So I decided to dial it back a bit and stick to map 7 which I found to be the best map for stockers.

[phunky_monkey]

That's a really nice gain, thanks for sharing. Must be a lot fuller through the mid-range now? And nice to be able to get a higher net result with 3 psi less, seems like they're definitely worthwhile.

I have some VTT inlets to go onto mine too, along with a Wagner Comp 2 'cooler and a yet to be determined intake. Then need to decide what I do tune-wise, as I have the cord for the MHD flash but am a little wary after seeing some of the Vic guys have a few knock issues on track with the 93 map running. Might go a custom tune from HPF or Southern BM here in Melbourne.

[martymil]

Talk to JD75 or Trebila they will help you with all your custom flash needs for mhd.

They do all my flashes for the 1M and 135
