    Eventuri intake to Forge TIP?

    Sure, attached, the part was from Merlin Motorsport: https://www.merlinmotorsport.co.uk/p/aluminium-air-hose-reducer-1-step-ar

    Eventuri intake to Forge TIP?

    Yes, I ran a 4-3.5" alloy step-down with the Forge TIP to the IE intake. The boys at Forge even sprayed it black to match for me when they swapped the inlet!

    Facelift Anybody running Unitronic stage 2?

    I've been running Unitronic Stg2 for over 2 years now, I do like the idea of flex fuel too but waiting to see what their Flex-Fuel upgrade involves before I make any changes. It runs just fine on UK 99RON, which is actually a pretty good power for daily. It's about 540hp on a nice cold day...

    Facelift Unitronic Inlet elbow

    Just embrace it and get a pallet with 60x10l of E98 in the garage ;)

    Facelift Unitronic Inlet elbow

    It's such as odd design. Are you still on the Uni 3" like me? What metrics will you taking before/after to compare? I now have got hold of the silicone bits to fit the 'bare' RHD Eventuri 4" I bought cheap, so would be useful to also take before/after and see if there's any measurable gains...

    Sportback Custom Flex Tune with DS1 + build

    I agree with the cast bit. I went with the IE downpipe, it is cast to the flexi pipe, the downside is keeping stock equivalent weight but I'm not bothered about that, it has a great balance between noise and very little rattle. I just need to get through UK emissions next month now, I have...

    Facelift Unitronic Inlet elbow

    Any update on this one? Just to remind you, it's easter weekend - perfect opportunity to get it fitted and give us all some feedback :icon thumright:

    Facelift Unitronic Inlet elbow

    Well done for taking the plunge! I will be interested to hear how this works out, seeing as we've both on the Unitronic 3". I have felt the car might have made a tiny step back vs the forge inlet, not enough to warrant change, but the 4" I hope will. The Eventuri does look like a smoother...

    New 2021 Audi e-tron GT

    Spent some time in a Taycan Turbo S recently, it's turned me... phenomenal machine, so capable and good fun. Sounds like the GT RS will be very similar. Don't get me wrong, the 5-pot is going nowhere but an EV will be the next family car I think.

    Anyone here running a Haldex Controller?

    Pressure = more rear bias. The controller is just altering pressure to increase/decrease engagement, the single knob is just changing one variable to increase/decrease the scaling to dial in hook-up. It has a complete brain in there with very complex map capabilities, just a shame it's so hard...

    Anyone here running a Haldex Controller?

    On the pot. Basically at about the 1/2 way mark the pump duty is "100%" which will give you something similar to stock pressure. You have 4 not very obvious points either way that will increment that in either direction of circa +/- 5%. If you just max it out you'll give the axles a hard time...

    Anyone here running a Haldex Controller?

    I have both the VdV and Iroz/Syvecs controllers. The bottom two are variants of the VdV, "piggy back" devices, I do really like the integration though. The piggy back is a safe way to play - you won't break anything. They all have pretty good interfaces, the VdV phone app can change quite...

    Air flow improvement

    You will have a flow restriction on the stock airbox, but what you have there is a pretty good "half way house" for money vs gain. As as has been said, take dyno figures with a pinch of salt, I've never bothered with it but run alot of logs and Dragy times which are a better "real world"...

    Should I go E85? Unitronic

    Ah Stg1+ E85 makes sense re: stock injectors. That run was April time, single-digit C. I do have a TTRS though which is good for a few 10ths over the RS3. It's still fast though - not actually seen a faster stock time tbh!

    Should I go E85? Unitronic

    The wastegate line on some cars had a length of rubber that could be prone to getting soft and collapsing, which will cause the car to stop making proper boost. On my 2018 it is a mostly metal variant so have left it, no issues. Regarding Ethanol... to run it on Unitronic you'll need the...

    Insurance telematics boxes

    I've worked on this stuff; their algorithms determine my typical drive to the shops as an 'aggressive driving' event. In terms of data - the device I worked with quite advanced with an accelerometer and GPS. At the back end there's clever software and analytics. It could serve up all your...

    Tuned cars !!

    Yeah that's my take-away from i too... alot of extra money spent to gain alot of power, but also put it in the unreliable and inconsistent camp. I mean I'd be taking the 911 as my favourite anyway, but it 'won' by virtue of being most consistent for me. I'd concur, "stage 2" has been reliable...

    Reyland rear discs350 mm

    Most popular because BTCC use them, as do many other racing series, and we all like to mimic racing cars :sunglasses: But, according to AP: When you cut a slot or drill a hole in a disc you impact heat transfer. The area around the slot or hole acts as a cool spot when the disc heats up, which...

    Sportback Reyland brake upgrade (front & rear), size advice

    Answer on this is yes. The rear caliper bracket pushes it outboard about 10mm, and the disc hat of course to match. As a result it bolts on with no requirement to modify or remove the rear guard, and I had a few mm clearance to it still.

    Sportback Reyland brake upgrade (front & rear), size advice

    Any performance disc is going to be some form of cast iron, and will rust. I'd think trying that spray paint some discs ship coated with, that the pad wears through, could be an idea to protect that inner bit and the tops (just mask up the bell). I think you could get away with 2mm less on the...
