My friend has one and it made a difference.

 

If it only makes 1 more whp. it makes more whp. Granted, if it only makes 1 hp for 265 bucks its going to be a lame mod choice. I'm no newbie to turbo cars so i don't have grand delusions of making 30 more whp. What i do expect out this though, is that i gain at least 10whp peak and at least 10 whp over the top end of my rpm band. This should be obvious why i expect this. It should hold boost better up top thus giving a better power band up top. I will start a new thread about this. If map wants to help me the dyno time ( $) i have the ability to test this back to back from megan.

 

^ I understand how it works and the benefits from having one. I have one and love it but it is not a MAP. I would be careful going to MAP to do a back to back test on their own product. No one would believe the results if there were any. Good luck with what you decide to do.

If you understand this, then why are fighting so hard to dispute any gains from one? ive all ready decided what im going to do. Luck has nothing to due with the test. either they want to be in on it or they don't. simple. Im extending an offer for you come have a front row seat during the dyno session if you would like. Im not saying its going to be a gain or not. Thats why im going to try it wanna race?

 

Thank you all for the kind words!

This is a large part of the reason why we have yet to do the testing

 

If you read, I was not "disputing" any gains! I am 200% for external dumps so before you become arrogant, maybe you should read the posts next time! I obviously have an external dump and that is one of the main reason why I believe I made 520 on 30psi in 90 degree heat!

First off, I was not telling you nor anyone else that they should not go external dump, I believe everyone should. Even the stock turbos because they tend to hold boost better in higher rpms than a recirculated 02. I was stating what I believe to be a better external dump 02 design. PERIOD! If you have any problems with what I believe you can call or shoot a pm to Robert, R/TErnie, English Racing or anyone else that I'm sure could guide you in the right direction.

Thank you for both your offers but I would rather not!

By the way, let me know when you have problems because the MAP dump doesn't allow the flapper to fully open

Have you somehow stumbled across a wastegate actuator with exceptionally long travel (in comparison to the stock and/or aftermarket units we are aware of)? Otherwise, I don't see how your statement above is relevant?

 

Whooooo. go easy there turbo. no one was bagging you. My offer to you sir is still on the table for you to come see first hand. btw. arrogance is bliss and yes i did read where you said "Originally Posted by BLKCarbonEVO See I don't believe that the stock turbos make more power on dumps"

 

Holy shnikes....is the top right picture as far as the flapper actually cracks when its fully open or am I missing something here??

 

MAP O2 dump purchased

 

You are correct sir, that is the full travel of the wastegate arm and as far open as that flapper will ever get. If an actuator with about a 1/2 inch more travel existed I'm sure that would help the boost creep issue even further, as you can see the flapper has plenty more room to travel within our housing

 

Chris Carey, do you think you can post up some more pics of the dump? i think when i place my order for the exedy twin, i'll probably scoop one of these up aswell.

 

You can find a few more images here

 

Oh wow thats crazy! No wonder theres problems. Youd think the thing would open completely.
So is it possible to do that? Couldnt anyone just cut the arm and weld in a center section to extend the arm a tad??

 

Unfortunately no as in that scenario the wastegate would always be partially open The issue here is the total travel of the actuator itself...
