MM Turbo upgrade 3071 or 3076 or ???

After taking my turbo apart to find out what size it is I have concluded it is a T04e 57 trim . According to the flow maps - this turbo should be capable of around 300whp and yet I pushed it to 350whp - fck what was I thinking ? !!!!!!
Anyway - If my turbo can do that then I guess it's reasonable to assume that the 3071 can be pushed to 400

Granted I can't imagine shoehorning a larger turbo into the location the GReddy manifold dictates but its a little disappointing to think the only way to reach 400 wheel with the kit is to run the turbo so far outside of its efficiency range.
When I first got on the RX-8 club, there were precious few people with turboed cars to begin with, and those few were shooting for the "holy grail" of 300 whp which everyone agreed would be more than enough for any street car. With the available upgrades now like the AccessPORT and BHR ignition hitting 300 whp is easy and everyone is looking at "double baller" status as the next target. I'm curious if its going to take a different kit to really start pushing the envelope.

Do you think that you are hurting the turbo's feelings by asking it to go outside its 70% flow map island?
Or, do you think you are physically hurting the turbo (or some other part of the system)?

Well, I guess that's a good point... but from everything I've read, the primary reason for picking a turbo is to maximize its efficiency to ward off additional heat and avoid surge. It just seems counter-intuitive to me to use a less efficient turbo and then use charge cooling to reach a target unless there is a compelling reason to use that less efficient option. If the primary reason for that is the space available I guess I understand it. I don't think the turbo is going to yell "Ouch my compressor wheel!!" if I put more boost through it...

Thankfully he's not posted the dyno charts otherwise there would be an army of people claiming they were doctored.

A good example, look at Esmeril. They were claiming 400 whp with their kit, and there were known failures with the kit and people got on them really hard until Chris posted a dyno showing what the kit could do. Sure there are still issues that people have, but it changed the environment from open hostility.
I'm not saying Jeff should post his dyno because honestly I don't give a rats *** if he hit 400 whp or not. He said he did and I believe him, but it won't change anything for me if he posts or doesn't post that. What is an issue is making such a big ******* deal over something that was a simple question:
"Does the kit hit the advertised horsepower, and if so does it do so despite operating outside the optimal efficiency."
It's a yes/no question, with no need to be blown up into a big thing with people guessing and mudslinging on various sides. If the turbo is outside its efficiency range and that is acceptable due to the space constraints and the desired spool time, great... just say so. Hinting the turbo has a different compressor wheel, or there is some kind of "magic" involved is inane.

I know it is not the only book and it is likely not the best, but a quick overview of Hartman's book could give anyone enough info to feel comfortable about these issues pretty much. I was looking over it again last night and was suprised that the 3071r is used in many examples.
Just fyi

If you're asking what kind of turbo comes in the upgrade that's one thing. Using Esmeril as an example would fit. In their case, Chris was making claims that their bolt on kit was capable of 400whp but there were not any dynographs to back up their claims.
Mazdamanaic has never claimed such high figures and IIRC 310whp was the advertised figure and so far I don't know a single instance where this power level was not reached.
If people are upset Jeff isn't talking about what's in his car then it's just tough. Nobody has to pull back the curtain and show the little man operating the controls.
Doh, beat me to it!

Perhaps I am confused to the purpose of this thread. My understanding is the question being asked is what kind of turbo is MazdaManiac running in his car. What you are expressing Aaron is what kind of a turbo is included in the Greddy Upgrade that MazdaManiac provides?
I do care that the website advertises it can hit 400 whp (so yes he does advertise that) and I'm hoping to move in that direction, but the compressor map doesn't seem to fit that target so I had a legitimate question about the turbo. I would of course be totally fine having the conversation in private, but my record in reaching Jeff is less than stellar, hence the thread.
I got the answer I needed (and assumed anyway) so you may all resume the normal RX8Club programming.

Read again:
The turbo included in the upgrade kit is capable of flowing enough air to produce up to 475 horsepower at the crank. That is over 400 horsepower at the wheels.
However, getting there will require major upgrades to other areas of the drivetrain, including but not limited to fuel injectors, ignition coils, intake and exhaust piping, fuel pump, cooling system upgrades, transmission upgrades, differential upgrades and suspension.
It is not an unrealistic expectation to get well into the 300+ HP* range without serious modification with this kit.
The primary goal is to take the existing GReddy kit and give it continuous power to redline and add 25 to 75 HP* to the numbers people are seeing with the GReddy kit alone.

I understand that, but as someone who has upgraded every single one of those things you list as needing major upgrades I was specifically referring to the line that says the turbo is capable of flowing enough air to produce up to 475 horsepower at the crank. It isn't a totally insane question to ask how that is possible if the compressor map is way off its efficiency island. I honestly don't understand why its such a big ******* deal? It's not an insane question to ask and I shouldn't have to pull teeth to get a simple yes or no answer.

I will now be offering my Turbo kit to the public!
This kit is capable of producing 900 crank HP. That is over 700HP at the wheels. However, getting there will require major upgrades to other areas of the drivetrain, including but not limited to fuel injectors, ignition coils, intake and exhaust piping, fuel pump, ported housings, extra rotors, a different turbo, cooling system upgrades, transmission upgrades, an LS1 swap, differential upgrades and suspension.
It is not an unrealistic expectation to get well into the 250+ HP* range without serious modification with this kit.
It is possible that I may have at one time in some way perhaps hit these numbers in my own car. I will niether confirm nor deny, nor comment on said numbers. However my kit may or may not, though probably not(though you could get lucky!) contain a turbo capable of these numbers.
To place an order simply go to my website. I will gladly assist you. If you have not recieved your order within 8 years please contact me by cheerokee smoke signal while holding your left hand behind your back. Any other forms of communication will be ignored. I cannot be responsible for unexpected winds blocking your signals.

Then again, I'm seriously considering an LS1 swap now so I can use Mawnee's new turbo kit... that sounds amazing! Fortunately I'm proficient at smoke signals already.
