He's already got more money then most would put into a stock appearing setup.
Ball bearing mod
External Gate
Get a Tubular Manifold
Where does it stop and at what point does it start not to be cost effective (I know you don't have a tubular manifold Tom).

 

Im pretty sure he is using an internal wastegate from the pic's.

 

I believe he meant to say external dump 02 housing. In which case I believe he's sponsored by the company. But I see smurfs point on all this. The stock frame WOW factor is still there on his set up. To a guy that doesn't sit on Evolution M, he's not going to WTF hit him if they race.

 

why switch to something that is completely unnecessary for the turbo? all an external wastegate is going to do, is allow for over spinning the turbo easier. the 25psi wastegates once tensioned right is better and safer for the turbo in the long run.

if you look where i made 650-660 last year that is holding a good 2-3psi across the board more.. i tried to turn the boost up like that on this current setup on my car and it would not hold that steady line.. so the preload needs to be adjusted (its not the same FP wastegate from last year - this ones Owen developments design), but first i need to figure out where the actuator is actually starting to move to safely adjust it without putting excessive tension on it.

so i must do testing first.. im completey fine with 600whp, but id like the curves to ride closer to the 600whp mark throughout.. not just touch it at 7k.

 

i would gain more topend for sure with a good tubular manifold.. but i want the setup to remain stock appearing for now.

im already happy with my car so it stops now.. i just know the wastegate is bleeding off excessively so id like to get the proper flow going so i can get the proper curves this turbo offers at these boost levels.

i have so much data from my journal fp black last year and the setup is identical aside from the catch can stuff.. so im overlaying graphs and stuff and the current way its running is not matching what it was doing last year when i try to run the turbo in its max power range.

i will test the actuator and go from there.. i am almost positive its on the conservative side because the company who made the turbo conversion is not used to high boost applications and are more so targeting road course cars which 35psi+ would be ridiculous to run.

 

its internal. theres no reason to have an external gate on a fp black when fp and others have true 25psi internal wastegates that actually work.

im sure if i connected my 3 port up i could get it to run 35 at redline without touching anything, but thats definitely the wrong way to approach the situation.. first thing you do is adjust the internal wastegate to flow properly and then go from there.

I know he had an internal gate on there. My point was that buying a stock frame turbo and doing all those things to it (BB, EWG, TB Mani, etc) kinda defeats the purpose of having a stock appearing turbo after all the money spent.

 

stock sleeper ftw.

 

Very nice.

 

hey hey hey now there is nothing wrong with getting a tubular manifold the rest of the stuff i agree with you on. Just so i know tscompusa HOW MUCH WAS the conversion total.

 

Def. nothing wrong with a tubular mani......I'm just saying once you do that, BB upgrade and EWG.....it defeats the purpose of going stock frame in the first place.

 

Its easy to say that after the fact...but the reality is most people start off one piece at a time with stock frame. That is the big draw of stock frame, you get to use all the same pieces you used with the stock turbo so you can piece it together over time. Spending 4-5k over 1 year or 2 isn't as tough as all at once ya know.

Anybody trying to push 600whp out of a stock frame in my mind would be better off with a t3 kit imo, but obviously its easier said after the fact and if the black can do it, why the hell not.

 

Overspeeding the turbo shouldnt be an issue with the DBB chra Tom. Thats the best thing about the DBB, it is almost impervious to overspeed.

 

uhhh.... bearing has nothing to do with over speeding the turbo. Spinning the turbo too fast to the point where it is chocking does nothing for performance and bearings don't change this.

Its physical limitations of the compressor wheels

 

I undertand this, however since people have gotten much more power from the turbo and the big downside was thrust bearing failure from the high speeds not lack of power Tom can push the limits without fear of killing the bearing section and the turbo. Push it hard to find out what it has in it then set it where you like it. HTA82 compressor wheels can do a lot.
