SpeedForceRacing

Actually it is SFR(Speed Force Racing) that builds the kit.SSR is one of our distibutors.The system has been complete for sometime.There is a 280+ dyno chart on our website.I will go to the dyno shop to get the 287 horsepower dyno chart.We have another RX-8 in the shop right now that will easily push over 300@ the wheels on the stock motor.It should be completed next week and the dynos the following week.We just used a larger T-4 turbo.The programming will be available for the TSI unit asap and programming for the Emanage will be available in a month or two.The thing about our kit is that it is not cheap and all the parts are high-end parts.You get what you pay for.If you are trying to compare out kit to Greddys then consider this............

We use an external Tial 46mm wastegate(that adds $500 to the cost of the kit-with the Greddy kit external wastegate is not an option)We use a full T-4 (adds another few hundred bucks to the kit compared to a small T-3 turbo) We build a 321SS header with a double slip fit connection(adds$500 to the price of a kit over a cast manifold) We use V-band clamp assemblies and a 3" 304SS downpipe(adds a few hundred more to each kit). Dont forget the blow-off vlave(add another $150 to the kit) and wait there is the injectors(add $400)Did you want the car to run right out of the box and make power? (Then you need to add in the cost of the engine management and boost control solenoid).Like I said, it is a high-end kit.The turbo has the potential to make 600+ at the wheels if you can run enough boost and lower your compression.You will never make that with a Greddy kit!

The bottom line is that the kit is done and finished.There is two kits.A tuner kit which comes with the turbo,headers,wastegate,intercooler,plumbing,etc.. ..and you tune it with whatever system you choose.The second kit is a complete kit from us with a pre-tuned engine management system,550cc injectors,etc......

Ofcourse we are always trying to improve our products and make them better this is why we have another RX-8 in here to exceed the elusive 300WHP mark.

Because it is superflous

Beside the fact that a "full" T4 is the wrong turbo for a typical street application, it is no more expensive than a T3.

Though a cast manifold is more durable and thermally efficient

V-clamp is just easy, not better. The cast manifold on the Greddy is in the same boat as the manifold as mentioned above.

Yeah, you need one of those.

Just injectors? Don't those need...

Oh, yes. Yes I did. It is a kit, right?

I guess controlling those injectors would have been difficult without it.

Or, rather, a high-end collection of parts. Not really a kit, now is it?

Or yours - without significant modification to the motor.

Jeff you are hijacking now :p

SFR/SSR whatever...just give us a basic summary

I'll pm hymee about a summary

then some moderator can clean up this thread

dstnRX8

what company is PTP, just wondering, when will it be available

Not a rotary.Look at most of the single turbo Rx-7's and see what they are running.

You need to read up on the abilites of 321SS over cast iron.If what you were saying was the case then F1 cars, Nascar and every other race orginizations would be using cast headers right?Besides that,we have been hearing about Greddy exhaust manifolds cracking on the Rx-8s,350z's and a few other cars they build turbos for.Now what?




Or, rather, a high-end collection of parts. Not really a kit, now is it?




I guess you could say the same thing about Greddys 'kit" now couldnt you? I dont know what your probelem is with us but drop it.We are trying to help people make more power and you are just knock us left and right because of........the fact that you have a Greddy kit?

Most of the single turbo RX-7s aren't running 7 to 9 PSI - the limit of the factory fuel injection system. If one doesn't purchase your "option" pack so that high boost is supported, the T4 is going to be so laggy as to be laughable, not to mention it will be sitting at or below the surge-limit line through most of its performance curve.
Shall I show you flow maps and explain them to you, or can you do that on your own?


I am well aware of the "abilites" of stainless steel. A cast iron manifold is a better choice for the street, F1 not withstanding. What an absurd comparison.
There have been no reports of the Greddy manifolds cracking that I have seen. You will have to produce those before I will even entertain that gratuitous claim as a defense for welded over cast manifolds.


Nope. The Greddy system is a kit. It comes in a box, you bolt it on and you drive away. There are no options and there are no part selections that are required to make it work. It is a complete kit.
You system is not a kit by a long shot.


I don't have the Greddy kit - I built my own system completely from scratch. Don't presume anything - you could have fiured that out on your own with a simple search.
I have no "problem" with you (I will assume that this was directed at me since you didn't manage to use the quote function correctly), but your claims have been, to date, spurious at best and I see too many impressionable people buying into your claims without understanding the limitations of what you are really offering.
This is a public thread and I will challenge you at my own leisure.

Speedforceracing (Tim )

If you do a search you would have noticed that Jeff (Mazdamaniac )built his own Turbo kit within 2 weeks of commencement .

Greedy as other forum members have copied Jeffs Tuning maps to use for their own mappings :D

You guys have been talking of producing one for How long ..........???? i hope you race faster than you manage to try and put out this kit , getting it fitted is the easy part lets see you Correctly tune one

I can just see all the blown up engines courtesy of speed force racing

Talk is cheap show us the finished correctly tuned product , then come back and do some boasting you clearly have taken on more than you can handle .

I don't see why there's all the negativity. I for one am happy that companies are trying to develop products to push the limits. I think its great that SFR is making this kit and I hope it does well. Everyone seems to think this will break the engine. I don't know why, and sure hope it won't as I plan to eventually get my Greddy kit to around the 280hp mark. Granted it has taken them along time to get this kit done, but ya know, they are they only people besides Greddy who have done it (and have it for sale). I don't see Pettit's, PTP's, or anyone else's actually ready to sell.

I don't think it will break the engine at all.
However, I do think it is quite possible that someone will order this "kit" and install it without understanding the engine management part of the system (and lack thereof in this "kit") and then pop their motor.

they sell it with a pretuned EMS

Are you saying T4 turbo PTP is using for their kit isn't a good street option for rx8??????
Since they will be offering any turbo I want for the kit if I didn't like T4,
what turbo will you recommend??
My hp goal is around 400whp.
Thanks

rotarygod

T4 is just a family of turbos. Depending on what trims you get, they can make anywhere from 300 hp to many times that. Not every T4 or T04 is the same. You can get a T-04 that will get you 400 hp.

The problem is in the engine management. You need to control this fuel very carefully so you don't blow anything up. You will also need to address your fuel issue as you don't have the capacity to hit that number with the stock fuel system. What turbo you have is irrelevant until you fix this.

Fortunately soon there will be a way to get a true standalone ecu onto the RX-8. I'm working on it. Not sure if I want to make the info public knowledge or not though.

I DO NOT understand why the US HKS does not HAVE THIS FOLLOWING INFO. Nearly everyone in Japan knows, shown in the Tokyo auto salon, and even talked about it in this forum -

HKS is bringing out a Rortex SUPERCHARGER! Much like the kit for Z33 (350Z).
I have the picture in my Jap mag, I think I should scan it and put it here.

No power figure yet but the price will be a million yen installed in Japan. Tuned by HKS F Con V Pro and have an intercooler with tubing coming out of the exisiting VFAD.

It is going to be available in Japan this summer.

It remains my favourite just because I want to be different. Although I like to see Hymee's blower.

The similar set up in Knight Sport - tuned by the stand alone ECU gives 284ps.

all hail, Rotarygod!!!

rkostolni

RotaryGod you would be the man if you could get the fuel management figured out. I am already saving for a stand alone, and will definitly be buying one when I think someone has the bugs worked out.

I would love to hear about anything you have made any progress on.

Check out the Megasquirt thread.

Oh do they? Which one now?
First it was an E-Manage with a Haltec E11 as an "option".
Then it went to a Tec3.
Now it is an HKS VCON for which they have yet to become an authorized dealer.

Mazsport is coming out with an upgraded greddy kit. They claim more then 300WHP.

rotarygod

That will be with a new slightly larger compressor wheel. I still doubt it will hit 400 hp though.

rkostolni

Anyone know if they are going to change anything with the turbine side. It seems that could be a big restriction.

JOHNRX8

New List:
Richard Paul - Supercharger
Hymee - Supercharger
Petitt - Supercharger
HKS - Supercharger
Blitz -Supercharger
Speedforce Racing - Turbo
A-Spec - Turbo
PTP - Turbo
Mazsport - Turbo Upgrade (Greddy)
Any others?

mike1324a

ssr engineering has a turbo kit

davefzr

SSR is SFR... They are just the promoting/distribution company though you can buy it directly from SFR...

mike1324a

Has anyone heard anything about the hks kit lately?
