I just switched to an RX6 single and already miss my seq. Pettit twins. The spool is quick on the RX6 but nothing kicks like a well tuned set of seq. twins.
I went with the RX6 because I thought it would feel like the seq. twins but without all the hoses and solenoids, but it is just not the same. I think I only gained about 30whp over my previous setup and it is only at the topend; torque is probably about the same but not as low in the rpms.
I'm already planning on getting a set of stage3s next year, so I'll be calling you Bryan
BTW, Bryan is a great guy. He helped me when I was rebuilding my Pettit twins even though I had never even bought anything from him.

Singles are for ultra high HP applications, Twins are for 425RWHP or less. Anything over that go single. Autocrossing and road racing people need to stay stock or they will be upped a class. Emmissions and inspections also restrict people from going single. It just depends on the application.

I was running about 13psi on the twins and currently running just over 14psi on the RX6 (1.00 on AVC-R) - untuned
My twins pulled very hard and quick off the line and I miss that. I did not have to rev the engine to launch.
BTW, I did not mention that I switched to a streetport also when I added the RX6, whereas I was only on a reman with the twins, so my topend increase is partially due to that.

From all this talk of the upgrade and everyones recommendations I will be going with a set myself. I need to keep visuals best I can with the smog people in the area. I am almost thinking it might be too much boost for me, if there were such a thing???

when it leads to detonation and engine failure....YES
at 17 psi, you need to mix 100 octane with pump
at 25 psi, you need to run C16, as Rich noted
in case you haven't checked gas prices lately, this stuff can eat your wallet

Who is runing the bnr's in sequential mode and making around 350+ rwhp! thats what i wanna know? cause i love sequential and i really dont wanna get away from it! I think an FD with 350 to 400 rwhp max is a well balanced car. If its runing sequentialy there might be some guys that get you on the strait line(not to many) but no one will touch you in and out of turns.

I am now running 10s in the leadings and don't get breakup anymore.
I haven't made it back to the dyno to go for a full 15 psi pass yet.

I'm going back and forth between BNR's and a GT35R/T4 setup. I'm tearing the engine apart and I'd rather not slap all the stock turbo crap back on if I don't have to.

c16 is 111 octain correct? a local place has 100 (more then 111 cause its still street legal) 111 and i believe 115, also sell it by the barrel. is race fuel all the same or is it all just a high octain leaded fuel? i think half the reason people switch to a non seg or single settup alota the time too is you loose so many sylanoids and such for the seq. that it cleans up the engine compartment nicely, i dont have to worry about smog. so thats why im looking into going non seq or medium single and ditching all the emmisions. i just hate the mess of wiring to deal with

I hate to be that guy again, but is their anything special, such as pressure reducing valves and stuff in the vaccum lines, that you need to do to run 15psi seq. I'm at 12-13 right now and when I get my injectors upgraded, hopefully by Christmas, I plan on running 15psi.
