forge twintake or ITG????

Okay, Ill try not to be dazzled by peak air flow figures then. I assumed with the rough calc for hp being worked out off airflow then more air flow would = more power
The thing is there are a few subtle differences between my car and Owens. The brakes, the map and the intake are the main three.
On the road, nothing separates the cars, but when my timing is advanced, its clear my car makes 5mph more than Owens on the 1/4 mile. Intake/map or combo, who knows.
Intake air logs would be interesting. Also, with Crail coming, hopefully Rob H and Blade will make it, so it will be good to compare a few Stage 2+ cars performance wise

What are your thoughts on the bum dyno? Been reading more and more about the Dbilas and getting very mixed reports about it. Some are saying that the Twintake was making 20bhp gains over the dbilas 
If this is true then on Stage 2+ yours would of made silly figures as didn't it make near 360 with the Dbilas?
I managed to get a 2000 mile old one for very good money and it's the only intake I can really use as the rest are to loud for work (customers in car etc) and I know exactly what the Dbilas sounds like as my mate has one on his Stage 2+ S3.
Just don't want to put it on if it's no better than stock intake with a panel filter as the filter and intake part of the Dbilas is very small IMO.
Am I going to be disappointed do you think mate?

No, absolutely not. I think the Dbilas is the most under rated intake there is. Everyone goes on about its small filter area, offset MAF placement, weight etc etc. The truth is that its very efficient and goes about doing what it does quietly.
My car made 337bhp @ the wheels with a Dbilas and it was pulling back at the top, probably with the RS4 valve not being there at the time. ZBoyds car made all but the same with an ITG intake and next stage of remap as it did with the previous stage map and a Dbilas.
Bum Dyno with the Evoms feels no different to me, infact, if anything, probably slower with the Evoms.
Get it fitted!

dbilias dyno proven to make 20hp less than the twintake
For the last few months we have been playing with intakes on both the K03 and K04 Golf GTi's. We first built a prototype of our own but we were dissapointed with the noise, its was all swooshing and wooshing, as if a hoover was fitted under the bonnet, but lacked that induction roar that most cars gain with a nice intake.
Another issue was the amount of noise at low throttle and low RPM, and lack of noise higher up the revs. This made 'everyday' driving a bit annoying if you wanted a subtle and quiet car t drive.
Our prototype was shelfed in favour of a panel filter, but performance dropped as expected. This was replaced shortly after with a Forge Twintake, kit fitted fantasticly well, performed well and sounded OK but was by no means quiet. We expected the enclosed filters to help, but they didnt.
Next up was a Dbilas, which is built extremely well and up to the usual Dbilas build quality that we expected but once fitted we did notice the car was far less* eager to pull at low RPM, the dyno also confirmed this with a loss of 20bhp over the Forge item! Once we investigated where the power had 'gone' it was clear it was the tiny airbox with a smaller filter than fitted to most petrol lawnmowers!
But the plus point was that the wooshing 'henry hoover' noises were gone. So off came the airbox to be replaced with an open cone (universal item we keep in stock) and road testing was impressive, no swooshing noises and lots of eagerness that we had lost with the airbox fitted. The dyno confirmed this as did the datalogs and power was 4bhp higher than with the twintake fitted. The setup sounded fantastic on the road, perfromed well on the road and dyno and logs look better than both the twintake and dbilas kits individually.
The conclusion is that if you want a quiet intake, its not the type of filter as in enclosed vs open, its the material that the intake tubing is manufactured from. The Forge item is made from very thin aluminium, the Dbilas is rather thick cast alloy. The thickness of the tubing dampens the noise of the rushing air. I think the ideal solution would be for a manufacturer to bring out an inlet which has all of the benefits of the Forge kit but with the a heavier gauge intake tubing, this will give the power gains, the quality and the silly swooshing noises will be eliminated. Or just buy the Dbilas kit and a universal filter

Yeah I read that too, and to be honest, I don't believe it.
Bearing in mind that an ITG will give 20 odd bhp gain on a mapped car, this puts the Dbilas on par with the stock engine cover. If that was the case, my car would never have made 364bhp at the fly or run a mid 13 second 1/4 mile at over 110mph.

totally agree with allen, i had dbilas on my car for 15000miles and it was great, not any differance between the VF and Dbilas from what i can feel.
if i had the option/money i would defo have kept my dbilas

fair point, but ignoring the difference, he did notice a drop off in power driving it. id like to see this new contraption he's made up though
