Are there pics in the old thread?

Shamblerock

Is our current power train components able to handle such an increase in power? How do you get around the cat burning up or does that have to go?

army_rx8

re-amemiya had to upgrade their clutch and l.s.d. with their turbo (it made 256whp and 325 torque i think)

SSR Engineering

No problem

Here are some old pics

Rotoman

You know what they say ,everything in moderation. I bet I can blow that clutch with the standard hp ratings... We can keep upgrading where-ever you want to go.. When I install this kit I'am not going to beat the **** out of it all day long... You also know the old saying - when you have the power you don't have to prove all the time.. If the clutch goes out alittle bit sooner than normal I replace it then with a heavier duty system and so on

rotarygod

Theoretically all you'd need to do is resize the turbo a little bit and retune the ecu. Big deal. It shouldn't be much of an issue.

davefzr

Do we have any assurance that our engines will not blow up after 2 months of use? When you state lifetime warranty is that just on the parts you provide?

Correct. The warranty is on the SSR kit, not our engines etc..

rotarygod

There isn't a single company anywhere that will offer a warranty against you damaging your engine. They only make the kit. They doin't prevent you from modifying it or abusing it. These are the most likely ways you will hurt something.

davefzr

What is considered abuse? I am the type of person who enjoys going to the race track and pushing my car to see what it can do. Will a turbo fail on me after a few outings to the track? Is there preventative maintenance that every FI owner should do if such an event is attended?

rotarygod

The biggest problem is that the term "abuse" is very subjective. What may be considered abuse to one may not be to another. It's like taking your car to the dealership to get a new clutch under warranty. They always say that it must have been abused. My friend's Z-28 killed a clutch just from bad luck and he had a hell of a time getting it fixed under warranty. The point is that if you kill it, it is very easy for a manufacturer to say you abused it and blame it on you.

Many RX-7's are track driven all the time with no issues. The key is always good tuning. If your system is tuned properly and you don't allow the engine to overheat, you should be fine at the track.

I'm sorry, did I hear you correctly? You got a 70% increase in power using 6 psi?
I never was able to do that!! I think half of that would be good.

Is there something magic about your air that gives you these numbers when the greedy kit at 7psi makes over 50hp less?

I'm not going to raise the BS flag yet until I hear why you think this can happen.
You might want to show me the math on this one.
Because if you have somehow gotten 100% efficency it still couldn't do it.
At least not according to the math.

Now Richard, you're not equating boost pressure to horsepower are you? :D

Theyre using a bigger turbo too

Snoochie

Of course I want to see the dynos first but I cannot help but say daaaaaaaamn.

foxman

time to start saving, this sounds like it is well worth the wait

mike0615

Hmmm, sounds like fun, but after talking to allot of mechanics, that little rotary engine we have doesn't take all that FI to well. they explain to me that the FD RX-7's engines only lasted about average of 50k miles cause the turbo was to much for it to handle. wouldn't the RX-8 have the same problem since it's basically the same 13-b engine with the multi-side ports? i just spent 1600 on HKS-hypermax 2 suspension, mainly cause i plan to track my car on a monthly basis. if u can convenience me that this turbo will run at those increased power outputs and last for a reasonable amount of miles, i'm gonna start saving again and dump my girlfriend. . i'm serious too, track racing is the funnest thing i have ever done in my life, even sex comes second now. well, just to let u know, i usually run my car on an average of 7k rpm for 30 min at a time on the track, so would u consider that abuse? oh yeah, is it possible to let us know about what price range ur talking about so i can start cutting back on expenses that aren't to important like cloths, food, water... ect. if its the real deal, i'm gonna get it if i have to sell my blood ever week or so. :D :p :p :p

I dont like the part were i got to change my injecters ..

I don't mean to hijack the thread - but are you planning some sort of shielding for the hot side of the turbo? I can't imagine what 1500? 2000? Degrees would do to the surrounding plastic, and the car's battery.

philodox

296whp from only 6psi of boost? By all means, if it's true I am VERY excited for the community as a whole, but I dont' see 6psi making 110+whp... regardless of how big the turbo is. What kind of turbo is it again and what's it's airflow rating?. Hell, for all we know when they did their runs their AFR's were high 12's and they were running 130+ octane racing fuel to keep it from detonating

Very funny 13, but my foot is not in my mouth. From the boost I can get the mass if you give me some other data. Did you notice that I did the math for philox engine and came very close to his output. Now the numbers for this installation should be close. Meaning temp and baro etc. If I remember right the answer was 242hp. that's 50 hp less than these guys are claiming. Now I don't know about anyone else but that is just to far off the theoretical number to be possable.

If the math is that far off why have it at all. All engineers should be taken out back and shot as worthless beings. Of no use to the world.

Giving every possable, even every impossable benefit of the doubt 6psi can only be 40% increase in intake. Now that would be no loss for working the air. Better then 100% efficency. Perpetual motion, call the Pentigon and the patent office.
Given 175 WHP to start x 1.4=245 A 70 hp increase and not probable due to reality.

So how do you get 120 hp increase?????????????????????
I'll tell you how, with a mass increase of 80% or a Pr increase of about 120% or 18 psi after the IC. Now that looks like three times what we have here and your going to point out that if you just doubled Jons increase you would be there so 14psi should do it. Ahhh now here is where what I preach comes in. You can't just add up the boost numbers because the air is hotter for the next 7psi and that group of psi's has less mass. On top of that with a turbo it is costing more percentage wise to get your higher boost due to the extra restriction of exhaust.
(Note; it will cost more with a supercharger too if it is the kind that becomes very inefficiant after the first few pounds(read roots).)

You can argue that saying your using a larger A/R but that get's us off on another topic best argued by rotarygod.

I've made my point and await counter points.

bureau13

Well, at least you now have a list of mechanics to avoid. Seriously, FD engines had issues because "the turbo was too much for it to handle?" Are you kidding me? That had NOTHING to do with the FD reliability problems. Inadequate cooling and an overly-complicated sequential twin turbo control system that tended to deteriorate in the presence of the aforementioned heat.

That said, I don't think you can draw many conclusions about the Renesis on the basis of its being "the same 13b engine with multi-side ports." That's sort of like saying two motors are alike because they're both V8s. They're very different animals, and the 13B-REW was designed from the start for forced induction, while the Renesis was not. There may be some down-the-road reliability issues with FI who knows? I can pretty much guarantee you that we WILL get reports from early adopters of blown engines, etc. As a number of people on the forum have stated about 8 million times, most of this will come down to tuning....if you try to push it without properly taking care of the tuning, you WILL have trouble.

Oh, I just read that part about a bigger turbo, I don't care if you took a turbo off one of those V16 92 Detroits! It of course would be running in surge anyway but you get my point.

dmp

I've got a feeling somebody will post up and say "Oh...I meant 292HP at the CRANK!"



:p (which we all know is impossible to measure for 99% of people - Shops/People often brag about claimed Crank HP to make their numbers sound higher)

twospoons_

Why would they need bigger injectors if they were running only 292hp crank?..
