Stock air box on single turbo


SupraT61

Recommended Posts

Here's the air box i made from the stock box, I'm thinking now it could be to restrictive :(

 

Iv got a t61 that I want running at 1.4 bar

 

Anybody else got any views?

The cars not mapped yet, I don't know if I should get it mapped with this box on or just buy a 4" cone filter then fit the box later and see if there's any difference :(

 

The reason I wanted to keep the stock air box is because I'm keeping the SMIC (replaced with new one) So the cooler air I start with the better as I don't have a large FMIC to cool it

Ryan.G did exactly the same on his GT4088 (slightly larger turbo) but I think he found it too restricive and changed it for a AEM or K&N filter. You might get away with it on a T61... one way to find out!

 

Looks like a tidy job :thumbs:

It's still worth giving it a try just to see how you get on. Ryan was running with WI, cams, a slightly larger turbo that was dyno'd at around the 560bhp mark. It might work fine on yours.

 

PS: You'd do well to put a blanket on that turbo, it really helps with the under bonnet temps

I just cant afford to get it mapped twice if it doesn't make the power using this box if you know where I'm coming from.

 

I'll have a look to see if I can duct an extra feed into it from inside the wing or something.

 

I'll be getting a turbo blanket also ;)

 

Thanks guys
