Questions for boosted N/a fellaz how much boost have you put through yours?
Like it says how much boost have you guys run?(Aaron Cake has been contacted about this but i'd like to get the information rolling....)
Are any of you guys running S5 rotors in your trubo 6 port projects? If so how much boost are you all getting safely?

I am using a s4 6 port, although it is not a stock motor, it is the motor I bought off of Jimmi325i. He built it for boost(He planned on using a 200 progressive NOS shot) The most boost I ran before the turbo blew was 11 psi. I had no knocks or anything like that, ran great. I plan on running 14psi when I get a new turbo.
Keep in mind my motor is different than most though. I also used Tii manifolds and a v mount intercooler. I know I have to upgrade my secondaries, I will run 680 primaries and probably 850 seconds. Rteck 1.5 and safc2. I switched to an n332 ecu to get some timing retard. I used to just have 550 and 680s I think It would be safer to have more fuel or atleats access to

thats what I did, ported the edges of the tii lim and added a little epoxy to weak areas. No need for 5th and 6th under boost.
1987rx7guy, I am not sure what exactly he did for boost, all I remember him telling me( a couple years now) was its been milled, tii intermediate, and some massive porting. You would have to contact him for exactly whats done.

The reason the previous thread was locked is because this has all been covered...
I was running about 8-10 PSI daily, 12PSI at the track (paper clip on wastegate line) and sometimes spiking to 14.
The amount of boost you can run on an engine is not a set number. Many things influence this, not the least of which is the type of turbo...

The answer is the same regardless of compression. It mostly depends on tuning. Fuel and timing are critical, and timing becomes especially important as you raise boost/compression.
I have been trying to keep a running total in my head on turbo NAs, both S4 and S5. But I can't think of any S5s that are still alive. This leads me to believe that perhaps the S5's compression is too high to turbocharge when running the stock ECU. But I could be mistaken...I wish more S5 owners would chime in.

By the spring i should have a a T2 engine running the S5 NA rotors (assuming i can find another rotor...) I'll give you guys a heads up as soon as it's done and broken in.
