Hey Rotarygod, you might be right , but don't say " these guys don't know what their talking about....

Because these guys are from down under and have a tremendous amount of knowledge
about rotaries.... But I still hope your right..

 

back to the original theme of this thread for a moment, congrats on a fantastic job! very, very impressive. now go enjoy that ride!

dd sends...

 

well... ptp it something like 360+ hp...
310 sounds scary

 

so someone help me do the math. how much power loss do you think is from the wheels to the crank? if 25% then he's at 413.33hp to the crank. If 20% then he's at 387.5hp to the crank.

 

neither...but you're opening a whole can of worms that this thread doesn't need to see

BTW i got first dibs on 400whp..then everyone else can have it

 

duh,
i just tought of this, are you doing scotts kit??????

beers

 

[QUOTE=epitrochoid]neither...but you're opening a whole can of worms that this thread doesn't need to see

how so?

 

Personally I would tune for a lower A/F ratio since this is a street car. Your really asking for trouble running close to 12.0 A/F ratios with pump gas on a boosted rotary at around 15psi. Tuning to the ragged edges does nothing for long term reliability. With the turbo running out of it's efficiency range, all it's doing is heating up the air and will increase the chances of detonation. Your not going to have any margin for error in a slightly lean situation with your current A/F ratio. Remember, a perfect tune can't always be relied upon when something else goes wrong. Example fuel injectors don't always spray perfect forever and not all fuel is the same. This is exactly why the FD was tuned to a A/F ratio of 10.0 and one of the reasons why my orginal Fd engine has over 100k and still runs perfect. Now I'm not suggesting you re-tune that rich, but I am suggesting you leave some more room for error. I'm tired of seeing our engines blow for stupid reasons.

 

T-von,
I agree, but Hybrid-RX8 may have several different maps he's flipping through. The interceptor can store up to 4 different maps. This map may not be what he uses for normal driving.
Or this might be his daily driving map.. and i'm totally wrong.

From talking to the person who originally tuned my e-manage. The Renesis seems to be able to handle a slightly leaner map than the 13b. Why is that? i'm not sure... and i can't speak for him. Then again i don't think any of our boosted owners here have hit high mileage on our cars yet. I guess time will tell if its possible or not.

Great numbers!!!

What octane were you running to get 310 WHP?

Also, are you using the stock injectors? If not, what is your fuel config?

Thanks!

 

congrats on the numbers !

 

From my understanding the zero overlap and less dilution of the intake is that reason. But still, why take that chance just for a few more ponies? Personally I wouldn't have any problem loosing say 20 hp with a higher A/F ratio if it saved me my engine over the long run. 20hp isn't worth a few grand for a rebuild IMHO.

 

Uh, I managed to get a T3/T4 into that spot without too much difficulty...

It flows plenty. The TD04-18G (similar, but SMALLER turbo) can flow way more than the 400+ CFM the Renesis ingests at WOT and 9 PSI.

 

great job on getting 309 WHP from your greddy. when i think about it, you get 200WHP at 3500RPM. i still prefer the smooth transtion of power from my na rotary to any other set ups.

 

Well, i would agree.. but i wouldn't go with a blanket map that is just pig rich. There is such a thing as being too rich and the severe problems that can come from it. Many horror stories in that world that I won't get into (not from me personally).

Still... it is possible Hybrid-RX8 has a different map that he uses for daily driving.

Wow. 5 pages later and Hybrid hasn't posted a single response to our questions....

I wonder what's up. Hope all is well...

 

hey guys..............everything is SPECTACULAR.... I've just been swamped at work.......... I'm going to try to get a video together for this weekend...

I'm going to try to get to some of your questions tonight...!!

 

Even though he said he has been busy with work, I know that if it was my car I would be out burning tons of gas having fun with that kinda power.

Congrats Hybrid, have fun with that monster.

 

<15% ( realistically it's closer to 10-12 % for a rear wheel drive car ). It's just not possible to loose that much power and not have something melt/break from the heat. ( the energy has to go somewhere... )

 

If you don't mind me asking, approx how much $$$ did this cost (in CDN Is it in the 5 - 7k range ??

 

Brice... I'm still ripping it on the way to work in the back streets... talk about short spurts of FUN!!!

Aseras... it should really be about 15%-17% loss from the crank to the wheels... power loss is not from heat but from the drivetrain..

I really have to give the kudos to Scott ... with his tuning ability and with his engine management system. I really think the key to this car hitting the power it did and having the driveability it has now (exactly like stock ... with loads of power ) was a result of installing ther Interceptor. Also, a big change beyond the 310 whp is the 252wtq! I've actually got wicked low end power now...

With the emanage, I was lucky to break 190 tq at a higher RPM even fully tuned. I had asked Scott why this was and he had explained to me it was the Interceptor's ability to control the variable intake. Maybe when he gets back to Florida he can chime in and explain the technicalities on how his EMS does this. Hell, I'm just a driver finally enjoying his car.

 

Yeah, you need to dyno! bragging rights for the Greddy/Emanage people! Low 13's on the street.... thats all I need... I just wanna surprise all these hillbillies around here
Nice numbers by the way!! congrats! hmm... Emanage or Interceptor-x!?

 

Mad Dog... I was able to hold boost until about 7500 rpm and it would start falling off to about 8 psi if I remember correct...

The internal wastegate on the Greddy T618Z turbo does suck but at the same time the turbo isn't capable of flow in the higher RPMS.

 

So you have 13psi at 7500 and 8psi at redline? Not too shabby....
That alone is giving a huge increase in power.

 

Here we go.. rpm,CFM chart... ( NA ) Figures sea level, 40C air...

I hate to tell you but it's pulling more than 400 cfm NA.. if my numbers are right...
