so if i do this can i just sent it out, bolt it on, then have mazdamaniac send me a map with the accessport? Can i run 300 HP with everything stock?

 

Ya, but I wouldnt go above that without injectors and ignition. MM wont just send you a map, youll have to do some logging, then he makes you a map based on your application, not like he says, ok, you have a BNR turbo, use this map. Its all "per customer" maps.

 

Right thats what i meant, thanks. I am strongly considering this upgrade!

 

very interested to know what happens to your PSI at higher rpm . I have had to work around the wastegate issues to get 10psi up top so interested to hear what happens with this setup ....

 

I would strongly reccomend it. Granted my cars not running yet but Bryan does excellent work. Not only are you getting a more efficient turbo that you can rev to 9k and still make power, but youre getting a water coole CHRA, which right there is worth the money. Less likely to heat up and destroy itself.

 

I have been ***** to the wall with this turbo and it just keeps pulling and pulling the higher it goes in the RPM band. I am very pleased. I am still running it on the stock wastegate, so I believe it was making 6.96 psi all the way up to redline. I do have a BC, so when I dyno it I hope to have it hold 10+ all the way to redline.

 

When are you going to dyno?

 

I predict 321 RWHP at 10 psi, and 348 RWHP at 12 psi

 

Man your good - based on the load logs.... I would not bet against Bryan.

 

jeez i wish i had a spare grand laying around. i'd send my turbo in a heartbeat.

 

I need some stickers and some graphics made. When you are ready I am sure something can be worked out.

 

i'll see if i can get you hooked up.

 

This Friday July 3rd.

 

I bet you will be pretty damn close. I will have to make another video of this thing at WOT! Its crazy and how much this thing just pulls and pulls. Got it up to 100 with no problem. Then I remembered at how I was only at 7 psi

 

I predict he will have wastegate issues and be limited to about 7 psi at redline because of it .
If so I have been through all this and have some suggestions for him

 

I have been able to get 10 psi on the old greddy turbo. So I have yet to mess with the boost controller since then. Hopefully I wont have the problem of only 7psi at redline. But PM me please and give me your suggestions

 

You may have got 10 psi - but up to what rpm ?
I would see what happens with your controller first because your setup is a bit different to mine but if you have no joy have a read of these two threads :

To be honest I dont know about what RPM it was. But Jeff messed with the BC and got it to reach 10 psi, but I know it didnt hold until redline. But Bryan can correct me if I am wrong, but I believe he addressed some of the wastegate issues I may have had. So I am hoping that I can hold 10-12 psi all the way to redline! I will mess with the boost controller on Friday.

 

j.cab, what time do you think you will be rolling? Looking forward to seeing this on the dyno Friday

 

be f'n carefull with it

 

Well I am leaving Whidbey Island around 4 am. Which should put us there at English Racing between 9-10am. If you PM me your number I can give you a call. The shop is in Camas Wa, which is about 25 miles or so from Portland. So my buddy is having a little bit of work done, but I can call you when the car is getting ready to go on the dyno. Or you can just go and hang out if you want.

 

what do you mean...I am running my alky kit as well. I think as long as my tune is fine, it should be okay.

 

As far as i know your turbo is similar (yours should be better) to what i have and it took me a long time to learn what to do to get over 300whp .


Have a read of the first link I posted it may be irrelevant but it may help if you encounter similar issues to what i've had

 

Oh man.... you're screwed then!!!

btw - the boost characteristics are different with a much more open AR trim, not to mention the porting of the Wastegate.

So we shall see.

 

Not really dude... the entire AR trim is completely different. This isn't a clipped Greddy turbine - this is a different turbine all together.
