we can always "test" a unit in my renesis-beater

 

50hp a 5psi sounds pretty good to me. Is this with a completely stock exhaust system? I thought you had the hymee muffler, or did you have that and more?

 

Doh! Wrong thread

 

We have the Hymee catback everything else is stock. Well, we do have someones shifter kit installed. No decals. I do have Hymees decal hidden in the glove box.
But it's written in Australian, no one would understand it anyway.

 

RP:
Are you going to tune your system for a max of 5psi or are you going for more?

Thanks

We are searching for a safe limit for the street driven Rx8.
Right now we are driving around with 6psi. It will get more soon.
We have to solve a problem that this car has always had but gets worse as we add pressure. It has nothing to do with the blower itself, it's in the car. And has been since it was new.

We are not looking for big dyno numbers, just what will give a good driving car with safe operation. We want to hold the saftey factor within reason. There is no limit for axial flow pressure but there is for your engine.
We don't want blown engines all over the place like some out there now.

 

Does the power curve feel similar to what is stock only more of it? That is what I would like more than anything.

 

Hold it up to a mirror. You'll be able to read it just fine.

 

Funny guy. Give me a call I have a question about that motor on the intake we talked about a long time back. I still think the problem is in there. Why don't I have your phone number, or do I?

The power curve does follow stock but it compounds, meaning the spread in power gets wider as you go up. That is do to the linier boost curve of axial flow.
In fact it did something I never saw on piston engines, it made the torque peak move up. I'm not sure if that is going to hold true when we finish tuning and adjusting boost.

 

have fred call me too and maybe i can come down and we'll bang heads on it.

 

yea I may not be able to bang heads with you guys... but I can be in charge of lunch....while listening....ha ha

 

Probably, 'cause he doesn't look like he has missed to many lunches.
(For you guys who haven't met him, he's one big happy caribbean man.)
You know that green guy in the movies who you don't want to make mad?

 

Okay so once people have this installed, will they be able to choose different pulleys for different levels of boost? If so, how high will this particular unit go before it becomes inefficient?

 

Green guy can be two people, the incredible hulk....or SHREK!

Take your pic :-p

 

Should I ask about tuning or... is it a secret or "wait and see"? I know that you originally wanted an ECU flash, but... developments in that area are ??? to none, and you are testing an Int-X right now. Just a little curious what this setup is going to look like.

Beautiful work thus far... can't wait to see what you can get once you have a properly running car.

 

he is working with the ceptorx.... scott was just out in cali.... tuned a bunch of turbos...

everyone wins.


beers

 

Thanks Swoope.

With no other complete option... I suppose you're right. That $1,600 just hurts though.

 

hurts less than a blown motor.

 

To be a tad flippant... hurts even less just to buy a faster car or one with better aftermarket support (or stay NA).

I've never knocked the Int-X as being a bad product. Just a bit pricey... particularly when all you want is a plug and play system (which is what both Richard and Pettite are after)...

It really does suck that the aftermarket for Mazdas in general (except for the RX-7) seems so poor. Subarus... great. Mitsubishi (DSM or Evo)... great. Mustang... amazing. GTO... great. Hell... VW GTI... great. All of them have flash tuner solutions (yes... multiple) already on the market. Oh well... c'est la vie...

Sorry for the thread jack.

 

You forgot the best Mazda sport car ever....MX-5/Miata. That car has a ton of aftermarket support.

From what I have read, in the future most ECU's will become tougher and tougher to crack. They will control just about every aspect of the vehicle, I wonder if the days of flash tunes are over.

 

^ Doh! How coulf I forget the Miata/MX-5... we'll see if it stays that way with the new one (in terms of power/engine mods).

 

no they are not

 

agreed... only getting better. Check out the MkV GTI (really any VAG car) and Legacy GT or the new Mustang to see. These cars' ECU has been cracked open wide and any kind of mod is possible... not just engine tuning! The best has yet to come...

 

This thread is getting just a little....
Keep up the GREAT work Richard. Can't wait to see this thing cruising around the streets of So Cal.

 

the more the ECU controls, the more flash tuning will allow.....

It will just take longer to crack and sort out initially thats all.....
