How is your new tb performing?
Do you have any issues with the plastic adapter melting, cracking or any other fault?
Are you able to make this in aluminium for us?
Many thanks for your efforts!

Still no issues. No cracking or melting. Intake air keeps it well cool (try and put a hand on your tb to get an idea of the temperature). Of course long term testing will be - long term - obviously. But I have done quite a lot of driving with it for now.

To make one in alu the design should change a little to work better on a lathe. I have no idea of cost but i think it would require a batch of around 10 to make it worthwhile. I dont think that interest is that high and that is why 3D printing is so useful for these things. I might ask my normal machineshop for a price.

If the original TB I good for about 330-350hp, what would this size be able to cope with? Did you change the MAF to match it?

Dont really think of the TB as a horsepower restrictor but more along just giving the engine the easiest breathing possible. The biggest restriction in my setup now is the MAF and I am looking for a suitable bigger replacement casing. I have not tried anything yet but I believe it will need a remap to cope with offset values or I will be running lean.

I think it would become a restriction eventually depending on how far you upgraded your engine. Defiantly get a new MAF and remap though.

I have a weird issue with my TB. As you can see from this pic the wires have been glued into the connector!! Could I swap the TB cover with the Porsche one, and basically use the whole cover as a connector? Otherwise I will have to find the right connector somewhere and have the wires all soldered onto it which I imagine will be a giant PITA

I'm considering the larger TB mod, but reading mixed thoughts on this online.

Does this actually make a difference and is it a simple plug in play install ?

As I said there is mixed opinions on this on the forum hence me asking the OP their views having run this mod for a while.

I can not tell you if that is possible. I would search for the connector first. They must be fairly standard.

It certainly increases throttle response. If hp is more or less I can not tell you. My bum tells me it is not less but I have no rr runs to back it up. The wiring is plug and play.
