Turblown vs Petit SC II (AUTO)

http://www.rx7store.net/Pettit_Racin...tage%202cs.htm

My question is which turbo would be the best for pure bolt-on without ECU dyno tuning.

Both sites claim they fit an automatic, bolt-on and 300rwp without additional parts. They are also the same price, price not being an issue anyways, does anyone have experience with these kits and can tell me what system is easiest to install in the garage and will run the best without tuning or additional parts?

Also, I think since the 4 port auto revs to 7k RPMs only, the PUC <=7kRPM may have to be taken into considering.
Thanks again

Where to begin....

No where.

Our turbo system will work on an AUTO, forum member 09Factor has been running our kit for 2+ years.

We can change the turbo to whatever power-band , or driving style you prefer. Smaller turbo = less lag, more low end torque

You will want to tune the car with any forced induction system, or you will blow the engine. Since cost is not a problem just fly out MazdaManiac to tune your car and drive away...

Ah bummer, one site did claim pure bolt on, no tuning. Just caught by marketing gimicks I guess. That was the Greddy with E-manage. I thought I could at least get a preset flash instead of driving the car in.

Anyways, thanks Turblown for answering my question.

The Greddy E-manage was known for blowing engine...

the Pettit is no longer available either...

von: if you think you can install forced induction WITHOUT some kind of tuning, then you obviously are in over your head and not prepared.

I guarantee you that if you don't tune any / every system out there, you will lose a motor. The E-Manage was infamous for this.
I've said it for a long time, Forced Induction (turbo or SC) doesn't kill motors, bad tuning kills motors.

As for additional parts; I would honestly recommend you look into certain things regardless of which system you pick.
Ignition Upgrade such as BHR
AccessPORT for tuning (will work for either)
Gauges - you WILL want to monitor certain parameters such as AFR, Boost, etc
Pod for said gauges
Midpipe since you'll quickly cook the stock cat
Cooling upgrades depending on where you live such as radiator, water pump, and thermostat
If you go with a turbo, you'll need a boost controller.

those are just what I would consider the basics.

Interesting, because it's listed FS on their website and I got as far as putting in my debit numbers for the Petit, just for test. So the MM upgrade is unavailable too?. Must be the economy or too many Rotaries poping and lawsuites.

the MM upgrade isn't available due to supply issues.
There's people still waiting for kits that were paid for a LONG time ago.

I would suggest calling Pettit; I keep hearing conflicting stories as to whether it's actually available or not but last I hear they hadn't made another batch of them so even if you could order one, it might take a while.
I'm not sure though, call them on Monday and try to get a definite answer.

I called Cam 2 weeks ago, they do not have any blowers for their kits. If it has changed I would be dissapointed they didnt e-mail me to let me know

I doubt it's changed, probably just an outdated website.

I think I decided to go Turblown based on the fact that MM is familiar with the setup and can send me a tuned system with the access port purchase. Maybe I'll have the first 300rwp auto. Or not

von: you still don't get how the tuning works, do you.
it will take several tunes to get your system working properly, MM can't just send you a "turblown turbo" map and have it work perfectly on your car.

That is what Greddy tried to do with the E-Manage and quickly learned that One Map does not fit all.

MM can definitely tune your car but it will take some input from you to make it work properly. Please take a look at his website and more importantly his MM Calibration service thread so you can fully understand the process and make it a smooth experience for all parties involved.

You are correct sir. I don't get it.

How far is MM from San Diego. Tried googling them, no contact us. I don't get that website. Are they a strictly online tuning shop?

Phoenix, AZ.

MazdaManiac is near Phoenix, Arizona. 6 hours away. He does travel for tuning, he was just up here not too long ago. He will street tune also, doesn't have to be dyno.

I just purchased the unit.

Wow I can't believe they can drive to SD for the tune. Interesting. I guess I wouldn't mind driving 6 hours. Depends what I'm doing and if the base tune can get me there.

Thanks guys

I'm sorry, but I see a blown motor in your near future. I'm not trying to be an ass. But, you sound like you just want something to bolt on, that give you moar powa.
Do you understand the dynamics of how a turbo operates? Would you recognize "DANGER TO MANIFOLD!!!"?
This isn't GT5, where you buy parts and add them to your car, and all is tickety-boo.
For the love of all rotary engines, do your research before you jump into this. No need to rush.

He is in good hands. He is not the one doing the install & Jeff is doing the tuning, 300rwhp is cake-walk on these cars.

Hmmm subscribed.

I don't know what injectors you have or plan on running. But for 300whp, You will need at least ID 2000's for the secondary injectors. Even if you uncap the 440 secondaries they stop at 880. so still not enough fuel.

When i did this on mine, i was fuel limited to 8psi. Anything over that, she went lean really quick.

EDIT:
von, between the Turblown setup and MM's tuning you have nothing to be worried about.
The first one Turblown built was for me, and its been running fine for close to 2 years. MM did the tuning.
quite rock solid and HAULS Donkey Butt!

I believe that 100%.
I just felt the need to be the devil's advocate.
Makes me feel like I should have just "bitten the bullet", instead of immersing myself in hours of research lol.

I don't know why people think you need to be an 8club fanboy to purchase a turbo and It's not like simply knowing how a turbo works will keep your engine from blowing up. A business like any other is there to help the customer make informed decisions, like the banks did in the pre realestate boom, no forum pre-reqs/post count necessary.

And I do beleive my engine will blow, but look at all the 8s that blow with no turbo at all. It's just a crapy car. One that I like.

09Factor,

I hear your're the Auto to beat :)

I was given the injector upgrade by Turblown during the purchase. Not sure if it was pri or sec but I'll cross that bridge when I take it to MM. Also have the Access Port.

...... hmm

I'd say 280-290 is easy. 300 can take a little more work to reach. Also the OP has an AT and not sure we have seen 300 obtained.

^^^ I think Phil got there, or is at least damn close

Phil's SC'd 8 isn't quite at 300. Yet.

Considering that in 7 years we STILL have not seen a 300whp AT I'd say that statement is just a tad optimistic . Not to mention that there are not that many 300whp MTs out there either .

but he has moneyz to spend

but then again not enough to start with a 6 spd instead

fanboi? Right.
You obviously have ZERO experience with your car. You probably regret the purchase, but are too far into it to give it up.
I was trying to give you advice, but now you just seem like a numpty kid who wants a better car than the one he's stuck with. Auto to Manual swap? Good luck.
Enjoy your "crappy car". When it blows, hopefully you'll get rid of it and buy a civic

For the sub'd. Car is finished and running, just waiting for MM to fly to SoCal to tune. If not, I won't have dyno results for at least six months as the car will sit or change ECUs from Cobb to something more user friendly and less controlled by MM

Some comments on the forum are already wrong as there are 4 port autos over 300. I'll send private messages to some of the sub'd with dyno results and keep off the forum.

Thanks

The Cobb is not an ECU, it's just a flash device and datalogger/code reader. And the Cobb Access port itself is very user friendly, you just have to know what you are doing when using the Cobb ATR software to tune. Even if you went with a stand alone ECU you would still need a tuner. MM is not the only person who can tune using a Cobb either, FYI. But he is great at it and would be your most logical choice.

As for the 300WHP four port comment, put up or shut up. By reading your last few posts it's pretty obvious you don't know a whole lot.

I didn't think I needed to know anything when paying someone else to do the work. I don't see how that statement (me not knowing about my car) has any bearing on the fact that 300 has been obtained by a 4 port.

I'm simply stating that the others who post their opinion as fact are wrong. Sorry I won't be posting my own personal numbers for you to see or arguing with you further.

Ofcourse Jeff at MM is not the only person who can tune, but he almost seems to control the Cobb market. I called Cobb support and the only support they provided was to call MM who ofcourse flat out said he won't respond to phone, text or email. Pluss, his tuning days are only once or twice a month and on work days for a few hours only. That is the kind of support you get when you buy Cobb. Being new, not a lot of "other tuners" have base maps making tunning take a lot longer and cost more money. Forget using MM base maps for those are password protected for some reason. Not bashing MM, I think Cobb being new has some fault and I think MM provides one of the best services, the fly to destination, live tunning, unforunately, this should have been my first choice as the remote tunning and support is not very flexible.

I took the car to another shop who said they know Cobb and 5 hours later at $150/hour said they can't figure it out. Some other issue with Cobb not sending commands to the ECU.

Anyways getting to the Turblown vs Petite topic back on track, I'd like to give good recommendations for the turblown kit. He fits all parts on an Rx8 before shipping to ensure proper fitment pluss he supports his product 100% and was available every day over instant message. The car is now running with this kit in under 30 days since purchasing the kit online. This included custom fabricating all parts and having a friend do the install after work.

Post numbers and photos or it didn't happen.

To make an educated decision on turbocharging an RX-8 , it would be necessary to know as much as you can comprehend. Not educating yourself is just stupid.

Saying a four port Renesis has made 300WHP is such a vague and silly statement. Did it make 300WHP for a day? Is it still putting down 300WHP? Why is it such a big freakin' secret? It's just retarded that you are being so secretive about what you supposedly know. I have found that most self proclaimed experts are not experts at all.

And your statements don't mean jack as far as I am concerned because you have no credit here. I could give a sh$t less what numbers you put down but if you are not interested in sharing or possibly proving people wrong then why are you here?

MM does not control the Cobb Market entirely. Is he the only vender of the Cobb AP for the RX-8? Yes. But you can choose to just buy the Cobb AP alone from MM and not use his tuning services. There are "base maps" available and if you did any research you would know that. But the chances are that those base maps would be useless to your particular build. MM's maps are his work product and he can choose to run his business as he pleases, why should he offer you a free map anyway? The Cobb is not new and many will disagree and tell you his live tuning service is actually pretty convenient.

Well that doesn't surprise me, a lot of shops think tuning the RX-8 is easy until they actually try it. And then they blame everything but themselves when the tune is jacked up and the motor blows. Cobb not sending commands to the ECU? What a boat load of bullshit.

I have heard great things about Turblown and they seem like a great outfit and I am actually considering some of their products. That said, a well designed turbo kit isn't worth a shit without proper tuning.

I 100% agree with 9K. If your gonna spend shit load of money + w/e tuning and not willing to show off your dyno numbers, somethin is wrong. If I could put down 300 whp thats bragging rights. It puts your ride off from others. Not a typical rx8 but originality and personality is what I respect.

yall give the guy a break---he came on the forum with a simple question--he got some good advice and proceeded. He admits he doesnt know how to do things himself, yet he is willing to pay for good services. Yea he made a statement that he will make 300 rwhp with an AT car. Turblown backed him up on that. He doesnt have to prove anything to anybody.
If yall dont believe you can get 300 rwhp from a 4 port engine, make it worth my while and hell i will do it! And it will be as reliable as any FI rx8.
Sorry to go on about this---i just remember when I first came in and how much I had to learn, and still am after over 8 years of messing with it. Yall are making good points and I think he gets it. So lets see what happens?

Thanks, 9k sounds like he wants to fight somebody haha. I don't remember saying I made 300rwp but whatever. And once MM dyno tunes my car, I won't be posting results no matter what horsepower. I'm just using the forum for information, not friends, bragging rights or social networking. Some statements that 9k and others said like having to comprehend all information regarding a turbo before professionals install one on my car makes me feel like I'm living in a fast and furious movie. The comments are as obscure as not double clutching.

best wishes for positive results that you are happy with

:lol: I'm not fighting you bro. But it sounds like you have it all figured out so rock on.

von--9K has some good points and it actually trying to help in his own way. He is actually a good guy.
You see--with this unique car once FI is professionally installed and tuned the owner still needs to have a great understanding of what is going on. This is a temperamental engine to add FI too. It's not one that you can just get done and then drive it with no problems. Yep FI can be done and made pretty reliable BUT, the owner needs to be aware of some warning signs of problems as they are going to come. And if the owner is not aware of these and the probable cause, then a catastrophic event could occur. We would hate to see that.
You sound like a very intelligent guy thats willing to do what is needed. A lot of good info is on this forum and believe it or not no one on this forum whats to see you have problems with your car.
You are certainly off to a good start with a solid build. Keep us posted. Glad to see another AT car get boosted.
OD

Good luck with your build, don't worry about what these guys say but knowledge is power! Seriosly though just post the numbers up, I'll be surprised if you get 300 hp, just my opinion though.

changed your mind already? :rolleyes:

Post numbers, ignore negative comments.

Fine, but MM doesn't fly to SD until 17th of Jan. So i'll let you know then. Tuning is already paid for

That's the spirit! :yelrotflm

Ignition breakup past 5k above 6psi. Towing car to shop to figure out what's up with ignition breakup

Oh boy.
