nope. you cant magically make boost faster just because your target boost level is higher. the only thing you can do is get a ecu boost control and try to force the gate to stay closed longer in hopes to hold more boost uptop.

 

That depends on your boost control. If it is a wastegate with a 30psi spring sure, but if it is an EBC that doesnt let any pressure go to the wg until boost is acheived it would not make it spool any slower. I usually dont allow my solenoid to starting cycling until about 2-3psi before target boost. That way it spools fast and holds proper boost till redline.

 

nice dude.. very clean! Magnus v5 is what id go with. talk to Aaron about that, im sure he will hook you up. That is my next manifold probably

 

like Batty just said IF the wastegate is set to stay closed longer DUH (stiffer spring). but just because you are set to run 40psi doesnt mean youre going to make your boost faster vs 30psi on a MBC or any boost controller for that matter.
I have real life experience logs infront of me showing no gains from running 34psi vs 40psi etc.. infact it takes longer to make 40psi then it does 34psi.. anyone that has a ****ING CLUE KNOWS THIS.

(i removed this comment because it was a bit rude)

 

what he's saying if im reading correctly is its easier to hit 30 psi on the way to 40 vs hitting 30 heading for 30.

 

and this is not true.. i have logs right infront of me showing its not. if i make 30psi 3800rpm im not going to make it faster with the boost set to 40psi.. its going to hit the 30psi at the same RPM level it took before and then after that wherever 40psi hits.. how the **** do you expect to make it hit 30psi faster just because the MBC is set to run more boost? maybe on a bleeder valve / pos MBC that constantly bleeds off extremely bad.. but not on a hallman pro where it has a needle hole bleeder valve......

you do understand theres a SPIKE to your boost target and then it tappers off? You cant manipulate the spike on a manual controller. and you cant make it build faster with a ebc/ ecu boost.. you can make it try to hold longer or control the boost so it doesnt spike etc on a ebc.

 

Speaking of wastegate staying closed longer when I was taking my turbo apart last weekend I noticed I had my FP 18psi wga sitting loose on the wg flapper rod. I remember preloading that effer! The retarded thing is that I remember checking the crack pressure and fullyopen pressure during install but what happened is when I attached the FP oil line the actuator/mount must have slid over a little (explains why my wastegate was opening at 14psi duh). With it installed correctly I should have a little better luck on the boost control. I'm debating on going with the FP 18psi wga set to ~20-22psi or just going with the FP 25psi wga. With my 25psi wga installed it fully opens by like 26-27psi though with barely any preload (or my pos gauge is off a c-hair) so I'm still noodling since I have both I could put on.

 

Thats the case i believe it may occur.

 

yes and that i agree with 100%. that makes sense of course. if its bleeding off more air to control the 30psi vs bleeding less for 40psi yes it will.. but as i said we are using ball and spring mbc's these days not bleeder valves.. its not 1990 anymore.

 

you know how to make sure it never cracks open prematurely? you pressurize the wg actuator slip the arm off then adjust the arm so its humanly impossible to slip it over unless you pressurize the wg and actuate the arm then you slip it on.. this way when it cracks open its barely cracking open at all.. you will feel the difference.

 

ya i shouldnt have said auto-x. i meant road course. auto-x is mostly parking lot cone and dogding and etc correct? if so then yes fp black would be a nitemare on a auto-x course.

 

Why would you want to hit 30 but over shoot it to 40, only to pull it back to 30 again.....DUMB

 

It's good that you admit that, because that is exactly what some of your opponents in this thread are getting at. That 100 lb-ft discrepancy between the BBK and the Black down low in the OP's graph would definitely be noticeable in an autocross or in any situation that favors response over top end. For some people, myself included, the best example of such a situation is driving the car daily.

We're spoiled in the Evo community to have turbos capable of 400 whp on pump gas while maintaining stock spool. That's plenty for a lot of guys who daily the car. The Black is NOT one of those turbos unless you're running a stroker, but of course it can handle a lot more power up top.

 

Jeez man, How many miles on that car? 6?

 

Great comparison thank you for sharing. For me it will be the bbk b once it is release but it is no secret it will be owned by the black in the quarter. I think it all depends on what the owner is looking for and the primary use, dd, auto x or drag. Again thanks for sharing the info, and for taking the time to post the graphs.
