6800 -7300rpm
8.0 - 8.5 psi
960-970 C exhaust
AFR - could be over 12
15 - 17 degrees advance - hard to pinpoint the exact number but it will be in that range . Split was around 14 degrees but not sure as I dont have that map to look at .

Here is the full map . Numbers on the far right are the base map numbers . Numers in the square are the modification to the base map .
so for 7000 and 7.4 psi we have 20-3= 17 degrees
green square is the one I think i was in - or half way to the next square on the right .

 

your exhaust temps are very hot. are they measured with a thermocouple or from some other source?
the consensus on ausrotary.com is in the 800deg c range is the zone for reliability measured at the ports pre-turbo. if you only have one probe measuring both rotors then you can have an averaging effect and one could be 800 the other 1100 and you get 970.

 

980°C is hot, but not unusual for a rotary.
Its not unusual for a high-output street rotary to see pre-turbo EGTs as high as 1100°C!
I wouldn't expect a motor to live very long if you sustained those sort of EGTs for any duration beyond a couple of seconds.
Cruise EGTs on a bone-stock RX-8 can be as high as 820°C.
I regularly hit 980°, but that is at 14 PSI, not 6.
That said, your ignition timing is pretty retarded.
Especially above 6500.

 

What i did today


Ready to go to rebuilders


Spagghetti junction

 

hope you know where all those parts, nuts, and bolts go

 

Well - i know the thing on the chain goes in here somewhere

 

wholly **** your apv ports are soooooo clean.. how many miles / km on that motor????

btw, im back did you miss me?

beers

 

I been awhol as well but - yeah of course we missed you

105000 km on the engine (65000 miles) - yeah they look pretty good . Maybe it's all the trackwork they get

 

Swoope - do you have any spare yellow injectors going cheap . wondering about upgrading the primaries....

 

if yellows are on a six port i have them. and really did you clean the avps up for that photo?? as mine looked like *** after 55k miles...

beers

 

That's about what mine looked like.....bit of carbon on the ends...and a bit of oilly stuff on the barrels that wiped right off.......about the same mileage too...and lots of track time

The old " redline a day" thing seems to hold out for carbon. Problem seems to be in the seals though

 

no clean up - straight out of motor .H ave been running Moreys FI cleaner for the last 6 or 7 tanks .....

 

ahhhhh,

that helps, but damn my hi way life!

i dont have photos on this computer. but if you do a search from years gone by. mine were ugly!!! at ~ 55k miles..

beers

 

brett: good to see the engine out, going to a good rotary rebuilder?

 

/\ hope so - only just found out about him . He is a rally driver and has built a number of engines but not a renesis yet ....

 

Sorry to hear about this.

Are you going to use the mazsport coils with the rebuilt engine?

Personally, I'd have recommended going back to the oem coils, and keeping boost to 9 psi for that kit. It's just not efficient enough to work well above that. High IAT spells trouble.

12 AFR wouldn't necessarily mean blown engine.

 

/\ well I'm not blaming the coils at this stage but yeah - that is another uncertainty ......


I would like to figure out what psi will give me the lowest IATs at 7000-7500 but the flow map cant really tell me that because i'm off it no matter what pressure i run

 

Regardless of blame, what do you plan to do differently once the engine is rebuilt?

 

good question
here is what i was thinking so far
*run 9-10 psi up til about 6200 then let it drop off to about 7psi from there on . I know that can work .
*Look into getting something to measure IATs
*Fit larger primary or secondary injectors and run a lot richer higher in the rev range
*Advance the ignition 3-4 degrees and montor EGTs
*make sure i dont push the car when it develops a misfire

 

you forgot:

* throw mazsport coils in the trash

 

everything I've read says it's the peak torque that you have to worry about detonation the most, the low and upper rpms are fine. Which is why Jeff's maps go rich in the 5.5k range, and leaner above and below that point.

So what you're doing is keeping the boost up till you're out of the danger zone then decreasing the pressure... doesn't sound like it's going to do what you think it will.



I installed the xgauge code for cat temp in my scangauge2, and it rocks

 

Lets see.....Bosch coils and Microtech ignition module = crap right

Mazsport bashing is one thing...but come on........

 

I agree, if for no other reason than you have one less possible problem to worry about in the mix.

 

Only because I have run it like that before and it ran sweet . Where i was having misfire issue was
1/at aux valve opening when running higher boost - this kinda points to the leaning off causing the misfire
2/Above about 6800 when at higher boost

Everything below this in the rev range was fine even when I ran 11 psi one time

 

Not bashing but at this stage in the game, it doesn't make sense to reinstall the Mazsport coils.
- dwell settings have been questionable for certain FI applications
AND
most importantly, what if a coil goes bad, ignitor freaks out? How is he going to replace that? Might as well install something where replacement parts / support is more readily available.
