PTP isn't even out yet. they havn't even put a price or specs on there site.

Fanman

Basing on their preliminary specs, and pricing and what we have seen in the previous posts, & various Mazda shows. If it comes in at $5,000-$5500 like they said, it will be right where it should be (vs. $7000+ of other vendors).

fenderlover

what are the preliminary hp specs and psi requirements

Fanman

They were getting about 275 whp with a T4 turbo setup. Preliminary price was about $5000-$5500 but with a Haltech system (which since has been swapped for a better HKS PF Con Pro unit). I expect price would go up, but they were saying 300 whp for the system now.

If ANYONE wants to come by the shop they can see that this car is still running and in good condition.Actually I would really,really,really appreciate if anyone could come by to see the car and then post their findings here so we can put all the accusations to rest. I dont know what else I can do to prove to people that the car is still perfect,no blown motor,no broke apex seals,etc.........

Yes we waited on an O2 sensor and then we took the car to the dyno.We have had problems connecting with our scanner to the OBD2 port.The port on this car has some sort of issues which cause it to disconnect with the slightest movement of the cable.We need to retrieve data from the ECU like short and long term fuel trims,ignition advance,coolant temps,etc.........with our scanner and cannot do that.So we have been trying to sort that out.Honestly we are in no big hurry to get dyno numbers to please a few people.We are not willing to take chances and try and tune this thing blindly for dyno results.When the car is finished we will make a post.

The funny thing that nobody has figured out though is that you dont have to wait for us to finish tuning or even use our EMS of choice if you want an SFR turbo system.You could buy our tuner kit and a Greddy Emanage,some injectors and there you go, turbo system with alot of potential for a moderate price.Actually there are a few guys who have realized this and ordered tuner kits from us.Hopefully they will post their own results soon.The fact is that the turbo system we build as well as the one that PTP builds has tons more potential then the Greddy system.However, its going to cost you quite a bit more then the Greddy kit.This is the price you will pay if you want more then what the Greddy kit has to offer.

SpeedForceRacing

For $5500 you can get a tuner kit.You have to figure out your own tuning and get some injectors though.The fact is that the EMS systems that are available for the Renesis that can control injectors directly,retard timing and control a boost solenoid cost $1500+ when everything is said and done. Now add the price of some injectors and possibly a fuel pump and you are approaching $2k on top of a $5000-5500 price tag.

Fanman

So you're still talking $7500 for your kit + good EMS, injectors, etc. We all know that smrx8 is talking about a complete & functional turbo kit.

SpeedForceRacing

No we are talking about $5500 for our kit + EMS, injectors,etc.......The fact is that even PTP will be forced to charge a premium for their kit too if they do in fact use the HKS F-con with their system from what I was understanding with my talks with John.The facts are the facts.A good EMS is going to cost $1500+ and there isnt anything, anyone can do about it.Now the Emanage Ultimate might be worthwhile, so this might be an option we look at down the road.

The thing eveyone overlooks with our kit is the high qaulity parts we use.I mean a Tial 46mm wastegate which holds boost till redline is far superior to the Greddys internal wastegate which bleeds off boost at high rpms.A full T4 turbo is much more expensive then a T3 turbo. Using $100 V-band clamps on our 3" 304SS exhaust adds to the cost.The battery relocation system that comes with our kit adds to the cost as does the stainless heat shield.321SS is very expensive to build headers with but was the only option with this rotary motor.We also provide a blow-off vlave with our basic system which is an added cost wihtt eh Greddy set-up.Like I said, the parts we use with our turbo system are much superior to the parts that Greddy uses with their kit.There is no way in hell we can drop the prices further then we have already.If you dont like it,dont buy it.But please dont continue to bash it.The fact is that you would not bash an F1 car because you drive a go-cart on the track would you

Finally.........Our turbo system has much better visual appeal! People who buy our kit and pop the hood have a big *** turbo and wastegate with polished piping in their face.When you open the hood with your Greddy kit you see an airfilter Really...... there is no comparison so I wish people would quit trying to compare apples to oranges.

I could of got the Greddy kit and be turbo'd by now, but instead, I am going to save my money for about another year or so and wait for the PTP and SFR kit to be worked on. Then from there, I'll have enough money and references of people running these kits and will decide from there. I see too many people dissing the SFR kit because of the price, but like Tim was talking about, this kit includes everything you need to reach that power, and then the option to push even more. The Greddy kit is a basic kit where you will need to add parts, bov, injectors, boost controller, etc and even with that, the turbo is too small to really push high into the HP range where the PTP/SFR kits are. If you want the power, you're going to need to dish out the money, that's plain and simple, and it's really getting old for Tim having to explain this all the time. You get what you pay for, just my two cents.

evilbada1

I already have the money,,but no PTP turbo kit available for me to buy lol
Once they're done with gt35r kit, i'll be one of the first to buy!!

MadDog

no one is saying that you don't have to pay for power. What we are saying is that we haven't seen enough evidence yet to say that the Renesis can handle that kind of output reliably. Until we see that evidence, its not worth spending the dough, even if it were cheaper than the GReddy. Why spend any $ if you are just going to kill your engine the first time you detonate with that kind of power? It just doesn't make any sense to try it until you see proof that it can work and work reliably. The proof of that falls on the vendors. We just want to see it in action, providing the promised output, reliably, maybe even on more than one testbed. Not an unreasonable request at all.

I don't think anyone here is even making explicit comparisons with the GReddy. I haven't seen a single post saying "why buy SFR when Greddy is so much cheaper?". They are kits with totally different aims. I think we all understand that. The only comparison I draw is between the amount of proof-of-concept presented here on the forum. There have been enough GReddy kits installed by members to say that the Reny can handle that level of power output without fear of blowing-up, even under detonation.

If you want to peddle a product, you have to advertise and answer the questions that people have - especially if there isn't enough of a customer base with your product installed to do it for you. That's how it is with the GReddy kit. There are quite a few people with the it installed to advertise for them. That's just not the case with SFR yet. All the flack that SFR gets on this forum is due to the fact that there has not been enough information shared. They can invite everyone they want down to their shop. But I don't see anyone beating down their door to do it. So, it seems to me the best thing is for them to generate the evidence on their own to share with the forum that their product preforms as advertised, and does so reliably.

If and when that happens, I am sure people will line-up, cash in hand. Then, and only then, is the price justified (even if its cheaper).

Fanman

Let me clarify. Your tuner kit will be $5500 + (according to your costs) a good EMS + injectors (which your kit does not include), etc will be a good $2000 min. So therefore the total when all is said & done you are still looking at $7500+ for the equipment.

I think the reason why people are saying you are expensive is that PTP gave a preliminary price of $5000-$5500 for their unit (with a Haltech). A complete turn key kit, not a tuner kit. Obviously with the HKS EMS unit it might go up. I'm sure if they came out and said that it will now be $7500 then they would get a hard time as well.

Nobody can/should compare your kit to the Greddy. Obviously your kit has much more with it. The question is that is it worth it for people (a question only they can answer). You are looking for a price no object crowd/max hp group vs. price dependent group. All good.

fenderlover

so basically we have 3 options

greddy $3500

SFR $7500

and soon PTP $5500 (estimate)

am i correct?

Fanman

No, I think an honest assessment is :

Greddy = $3100 ($2900 + BOV) = 230-240 whp

Greddy (with Interceptor/good EMS & Injectors) = $5,000 = 270-280 whp (not counting the 12.5 psi runs that showed 292 whp)

PTP Motorsports = $6000 (estimated, & assuming with new HKS EMS it will be a bit pricier than original $5000-$5500 turbo kit with Haltech) = 300 whp (standard tune)

SSR/SFR Racing = $7500 = 300 whp (standard tune)

gh0st

PTP is going to a more expensive turbo. i suspect prices will go up

All I can tell you is that I wouldn't trade my Greddy/Mazsport Intercetor-X for anything.I have driven the car for monthes,and it not only hauls a$$ but is so smooth around town that the drivability is seamless.It spools so fast it seems that you are always in boost, and really pulls.

fenderlover

so wut it comes down to is which is more power full

ptp or sfr. unfortunattaly we wont know until ptp releases

Fanman

And pretty much SSR/SFR as well. Only a very few out there so far, and no new dynos. Both these are in "very close" to production/release phase.

If it means anything, you are in Texas, PTP is in Texas as well.

SpeedForceRacing

I understand the points/concerns you guys have and we will try to address these by doing what we do best and that is proving it.We understand that our target market will be smaller then that of Greddys.We knew our price would be higher.We except the fact that not everyone will be willing to spend the bucks that we want for our system.

The crappy thing is that the EMS is killing it for the Renesis because these EMS systems cost so much.It adds a significant cost to the system.

For all the other turbo kit(G35,350Z,Altima,Maxima,Sentra,S2000,Porsche,BM W,Scion,Supra,
Focus,etc.....) we build, we use an EMS system that costs $500 and controls fuel and timing.Unfortunately it doesnt work on the RX-8.When something is available that works well and doesnt cost an arm and a leg then we will definitely look into it.We would like to see our system come in the $6500 range one day with all the bells and whistles(EMS included).


As far as the Renesis goes,we believe it is capable of sustaning close to 400WHP reliably on a stock motor!We have seen people running crazy boost levels without problems.We will still stay conservative for the moment and run around 8-10 psi with our system and see what we get.So stay tuned because you will all be in for a nice suprise very soon.

fenderlover

we just need to see the in depth specifications of all the turbos before an educated choice can be made.

terrypk1

Here is something interesting.
As i read from a recent mag(did a compare between TT,Votex Mustang,Greddy RX8), after installing the Greddy kit, the RX8 lost it's DSC and ABS function. As a result, the Greddy RX8's breaking distance was much more than the stock one. My brother told me that it was because they changed the stock ECU to Greddy thing.
Can anyone tell me that is there any connection among the ECU, ABS, and DSC?
Does the SFR turbo kit do the same as the greddy in terms of no traction control?

fenderlover

stupid question:

what's an ABS and DSC?

Fanman

No, the reason they lost ABS was not because of the turbo kit, it's because they replaced the stock braking system with their GREX Braking system & disabled the ABS & traction control. The turbo kit had nothing to do with it. I have it on mine & my ABS & DSC work fine.

ABS = Anti Lock Braking system

DSC = Dynamic Stability Control (our traction & stability control unit).

fenderlover

thx fanman lol

if u want to upgrade your braking system what can u do to keep your ABS?

fenderlover
