I was wondering if anyone has ever found this out? Being a student has cut my hours short lately so I haven't had the extra cash to buy the intake piping and have the motor pulled to install it. So I am wondering if anyone has ever figured this out.

I know I made 657rwhp @ 5000rpm with 22psi through them with a 3071. I'm going to crank the boost up tomorrow back to 20-22psi with the 3076's and see how far I can get. I guess we will know hopefully tomorrow as long as I make it home from work tonight.

I would strongly consider new hoses at that boost level.

 

My hoses are upgraded. I am using AP Engineering ones. My intake pipes that go from the turbos to the actual V-Flow is still stock.

 

Sorry, my mistake. I dont know the answer to that question

 

I can tell you though that the Silicone hoses can hold 30-40psi with a capped in before it shoots the othersides cap off.. LOL! Don't ask me how I know this.

 

well colorinc had issues with his 20gs , choking up top when he cranked up the boost.

 

That's a really good question because I have always used them but a few times that I did 700 cars without they would make good power. The turbo's surely do have to work harder. Your turbo's are big enough that you could be fine till you want more efficiant power.

AWE and EVO get 700+ out of the 997TT's with stock crappy piping now. That's not to say that the first car to get a set won't make more power and respond better.

So I guess yes and no. Maybe wait till you get injectors and do the whole deal...or at clutch time.

 

this is true!!

 

Years ago, when I first installed an early EVO GT640 kit on my car, I started off with the stock intake piping. I then added the V-Flow and FVD Intake Plenum. The combination of the 2 added pieces increased boost by 0.1 to 0.15 bar. Don't know if that helps you out at all.

 

Good observation...I think that about covers it.

 

I have the S-Car-Go carbon fiber intake piping

 

How much was that Sean, and are there other options?

 

There are a few options: Gembala, FVD, EVO...

I chose the EVOMS, as it is very well built - I think the piping is ABS plastic and it's about 1/4" thick and very strong. This is not a pipe you want to become compromised from rubbing and it's very tightly pinned between the motor and fire wall, so I think it takes a fair amount of abuse...IMO, the intakes with the ribbed hose look like they could wear through fairly easily after a while and result in the turbos/motor sucking in whatever finds it's way to the hole.

Ryan,

2K...S-Car-Go is expensive but high quality.

 

A month ago I was looking at hotrodding a stock tt with k24/20's.
At first I didn't want to spend the cash on the intake/pumps/injectors. From my research I came to realize the Protomotive intake was one of the best bang for bucks upgrade when it comes to engine mods.
I'd highly recommend it.
Colorinc, what exactly was going on with your new turbo setup?
