lets start a sweepstake

[Janner_Sy]

fitted it the wrong way id like to say i never saw that coming.

This is intresting....
I never read instructions... but there is an embossed arrow at one end of the filter body which I assumed is flow direction.
How have you interpreted this?

....Jim at JKM interpreted it opposite to myself and, though I didn't know it at the time, Forge's designers, but according to conventional orientation. I bowed to Jim's experience.

I decided to check it with Forge later and hence the mistake was discovered.

I agree with Forge's intention that the small arrow indicates suction when pointing inwards and delivery when pointing outwards but you could argue (as Jim did) the other way. We all agree it's ambiguous and Forge are revising their instructions accordingly.

To those with wrongly orientated filters:
Don't worry, no harm will be done but soft brush household vacuum (not high pressure air gun!) the filter before reinstalling correctly.

how did it sound on the dyno?

[DanoGTI]

I reckon it will lose performance   

176bhp/189 torques

We've all been conned

....JKM's fan is so loud that it was difficult to hear. Driving, it's not as loud or raucous as an EVOMS. I wonder if it'll sound different after the filters are turned around - It will also place the velocity cap at the delivery end as intended instead of the suction end.

You'll get the chance to hear it in real life sooner or later.

JonnyC of course fitted his the correct way around - Canny fellow.

Well you know, it IS possible that could be the case! It would then have everyone at Forge running around in circles.

By dyno-ing it again on Wednesday with 'wrong' orientation we'll establish a same day datum for any changes when the 'right' orientation is dyno'd immediately afterwards.

The logic, expectation, and word from Forge is that there should be a small bhp increase but also a further small improvement to the torque curve (which is good anyway as is). As JKM and myself are each independent and will tell it like it is, it will be an independent test.

Currently you might say that even in the worst case scenario with the filters 'cart-before-the-horse', the Twintake performs very well. 

I think Keith will be back at JKM next week too

For the sake of the sweepstake I'm going to inform that the Carbonio datum dyno test plotted 238.3 bhp / 270 ft lb.

[Janner_Sy]

your before graph was 238.3bhp 270Ibft . that seems quite low on power for a stage 2 even without an intake. are you running quite conservative settings on your map.

be interested to see whatthe maf reading is though. Logging mine yesterday with ben it made 202g/s. (cold day though)

Well those Maf reading Sy make 249bhp.

according to REVO the MAF for a stage 2+ is 190-205. 249bhp without taking timing into consideration is ok tbh

ens car made 260bhp on JKMs yet only gets peak maf of 195g/s

....I'd have to ask JKM what my MAF readings were - Such info starts to go over my head. I just look at the curve shapes, where they plot, and the bhp and torque. Oh, and the AFR plot.

I'll try and post such info as MAF readings in my Twintake review.

apologies for messed up excel sheet not the best at this vagcom lark

but it shows -   peak flow at 227 g/s  - is this good?

Don't you divide by 0.8 to get bhp???  Which makes it 284, or am I getting confused?

Correct but the OP really needs to post up at what rpm that max value was obtained.
