I am Putting my 3rd gen back together with a street ported 3mm seal motor and a 62-1turbo with a 96 a/r. I am using 850cc all around and an Super AFC for the time being. It is just going to until I am ready to install my TEC II. I am new to the rotary scene so my question is, roughly how much boost do you think I can run and how much power do you think I can put down with that much fuel... I have a chassis dyno with wideband so i am going to tune carefully just looking for past experience or opinion..

.96?? is that the exhaust A/R?? well you could be looking at
30% up with the 60-1 and running the same boost levels. As
for BOOST levels the 3mm seals can take the abuse which means
as much boost as you want as long at you don't detonate. Then
u have to be looking for an aftermarket ECU ....

 

.96?? is that the exhaust A/R??

Yes that is the exhaust A/R

This is not the first car i have ever built or tuned, I know that i can run as much boost as i want as long as i do not detonate.....


My question is FD specific meaning has anybody run this set-up before or had some sort of experience with it so when i put it on the Dyno i have something to go on...

ok then 550 prim's and 850cc secondaries 12psi boost then start
risking things up the high end!!!

PS:45-50PSI fuel pressure!!

 

I wrote a web page to help figure out how much HP your fuel system will support:

The SuperAFC and stock ECU are a bad combination for tuning a 3rd gen because I think the S-AFC just tells the ECU you are running more boost to get more fuel, which makes you hit the fuel cut sooner. I would wait until you get proper engine control before you mash the gas pedal or you might need to get a new engine. Rotaries do not survive a lot of detonation.
