Therm, That is sorta the point but right at the end you went astray. Doesn't matter if he cooled it more. It would be only a slight help. You are still putting more mass in there then the static compression along with the dynamic compression can take. There is a limit based on the fuel that normal combustion will can be supported. You could run methenol and get away with a lot more boost.

The intercooler allows you to tune a bit more because you are not on the thermal limit of the internal parts. Note, the IC does not give you any more mass, it only cools what it got. If the internal parts could stand the temp you would leave the heat in there to help combustion. In jet engines the air comes out of the compressor after a little inernal cooling at say 800f. But they have nicle alloy hot sections. If they could run hotter they would.

Every degree that goes in carrys through to the exhaust. On top of that it is in there during the process of combustion and if the parts are on the limit you must get that heat out before it goes in.

The more you raise the heat delta the more expansion, more power.
On a boat you can get the charge down to almost water temp if you wanted to carry that much cooler on board. But there comes a point where it is antiproductive. I don't know a particular point that this is. It will vary with the insallation and desired results. This is why they seem to be raising pleasure boat engines manifold pressure. I know the CAT engines just keep getting more power as time goes by. And it is the same basic engine.

 

does anyone know what kind of gas they will be running in the car that made 290? also, i am not very good at figuring out how fast a car will run, about what would 290 hp do to a 1/4 mile time if everything holds together?

Well you tell me when you come up with one of these Perfect systems.

Roket rider, Keith from SFR told me pump gas , I believe that would be 93 octane

 

By no means does adding such things as water injection take the integrity of the kit away. A volvo is apples to oranges to a rotary, and when you can actually cool the combustion temperature it therefore allows for safer power (simply put). As for the "poor design", the pictures and dyno's speak for themselves.

 

Why not tune the system without the WI...and have the WI as a failsafe at high boost. I disagree with using a map tuned specifically for a WI system. I wouldn't want to suddenly run out of water while flying down a straight at WOT and suddenly enter a state which could result in massive engine debris hitting the car behind you on the track.

If you are tuning with the WI...are you going to have some sort of warning system in place when the water gets low? A possible ability to cut back the boost if the WI has run out?

 

Hold on there Elvis. I wasn't bashing your kit whatsoever. I was bashing...er disagreeing...with using water injection to raise the safe boost level (which is poor design). As you can see in my post, safer power was what I was using the water for. I didn't chip it at 15psi then add water so I could raise the boost to 20. 15psi was well within the design limits of the stock Volvo intercooler, but 20 would generate too much heat (i'm ignoring the mitsu turbo's capability, it obviously can't do 20psi with any efficiency). I used WI for summertime peace of mind.

And "As for the "poor design"" I was refering to any kit that relies on WI to run at advertised power. Not your kit (assuming you're not going to need WI to run at advertised power :p)

So relax, have a beer, it's Friday

 

Our system is and has been tuned the whole time without WI. It's just an option for those that want the extra security

 

Sounds like a lot of people bitchin'. !!
Of course you can doctor Dyno runs! We have a Dynapak at Fountain Motorsports for race car development, some product develpoment work for mfg's (Stratmosphere and others) ......and the occasional daily driver hop-up! The Dyna-pak is supposed to be the most accurate, repeatable, etc.....and it seems to be from our perspective. HOWEVER, if I know that more dense air will effect my readings, I can 'pretend' I am at a higher elevation and have the computer show 'corrected' readings and viola' MORE HORSEPOWER!!!
You should ALWAYS take these claims with a grain of salt, if a mfg. says 20 hp gain it was probably the best of 3 or 4 runs, yada yada yada. every thing I've seen about my RX8 seems to point out that any gains from various product are modest at best. A cpl hp here, a cpl there.
300hp with forced induction at a modest boost for reliability and drivability sounds pretty darn good to me.
And I have the Dyno to prove it to myself that it works.
I'll be glad to check out SSR's once it has been out a bit longer and any potential bugs are worked out.

 

Ah awesome. I misunderstood the original post, as it seemed you were reaching the boost level with WI...aka not being able to run at that psi without the WI firing. Danke for the correction.

 

Hey guys SFR posted some new pictures of what I believe is the finished product on their Turbo for the RX8 on their web site.. It shows the heat shield installed and I see the exhaust is heat wrapped..

Hey SFR/SSR , does that heat wrap come with the kit, I did'nt see in the list, or is that something I can find easily at the stores, let me know...

 

Yes the heatwrap comes with the kit, same with the shielding and the battery relocation.

 

Thanks SSR/SFR , just was checking all final pieces, since mine is the first one out the door. I 'am looking forward to this sytem...

 

No problem rotoman, anymore questions just shoot

 

OK, next , when will see the new Dyno posted showimng the latest hp figures with the new injectors...

 

We have to get the chart from the dyno shop on monday and we can scan and post it then.

 

I don't want to sort through 22 pages so sorry if you guys already covered this, but I've heard the stock transmission isn't very bulletproof and at almost 300 whp, did you have to replace the clutch? Do you recommend some transmission mods? Thanks.

 

And it's monday... the end of monday too. So we all demand a dyno chart or we will doubt you forever.

 

If any of you have doubts you can feel free to call The Dyno Shop, www.thedynoshop.com . We still have to pick the new chart up.

 

Speak for yourself.. I really believe if any of you had the opportunity to drive SSR/SFR's turbo kit, you would not be making some of these comments. Your mind would be in the back seat of the car because it just blew you away... Any car that is making an additional 115 whp over stock would tend to do that.

 

Guys we waited this long another day is no big deal.. It's funny with the internet everything is so fast we forget all the things we have to do during our work day. So I guess what I'am saying is , there's only so much that can be done in a day..

 

More of the same... We know you have to pick up the chart but don't PROMISE something if you don't know if you are going to have it. Better say "sometime next week we will post the dyno charts and people will expect it anytime from monday to friday.

I ordered my greddy kit today. Good luck to all of you that are waiting on this kit.

 

man you guys are tough on people. let the man do his work...hes working on it!
btw mazda champion, did you ever promise something and not come through on time?
good luck with your greddy, and hope you dont need tuning help! hehe

 

Everyone wants everything yesterday, We have some great members and yet some whinners, But good luck on your Greddy Turbo.. Let us know when you get it..

The point is not being able to meet the date everytime, in several occasions.
I'd prefer to be told "we will post it sometime next week" than we'll post it on monday and not post anything. That makes you lose confidence. And by the way SSR, why should I call the dyno shop since you are the one trying to sell the product??? Remember you have competitors, if you had a monopoly that'd work differently, but not in this case.
