I want to know how much boost you can work on a RX-7 for a every day car
with the differents mods.
Please post your mods and your max boost

 

13 psi, low mileage daily driver
mods in sig

 

^Adam's the man

 

I'm also runing 13PSI but on less mods and the same ECU... seems like plenty. I have another ECU tuned fro 14.7(1 BAR) but I dont think I will be using it and if I do I'll still use a manual boost controller to bring it down to 13PSI

 

I was running 11 psi, with a downpipe, gutted cat, stock catback, blitz intake, and a manual bleed Home Depot Special boost controller. It was non-sequential too. Lost the motor due to an overheat but never stuttered or anything from detonation. Stock ECU.

 

I don't think it's the boost that kills, but rather the detonation (via A/F ratios, gas, octane )and additional elements that makes all the difference in the world on whether or not ur apex seals go kaboom.

 

14 lbs on pfc (nice and rich) 3" downpipe, 3" midpipe, intake, fuel pump. everything else stock, on low miles. Spring time will be non-sequential, dp, mp, cat-back (gt-spec or nur-spec), intake, radiator, FMIC and some bigger injectors, and im undecided on psi for now.

 

where do you think the extra air comes from to cause the detonation?

 

oh, i run 13 also. CA, IC, DP, MP, CB, PFC

 

13lbs too...see sig

 

BTW I think a big difference is the difference between Cali **** gas and everyone else. I had no problem running the 11lbs of boost on 93 octane.

 

20 lbs.

 

13psi with mods in the sig.

 

im on a low conservative 8psi non seq

cb, dp, upgraded smic, 2 stage bc, intake

 

IC, DP, MP, CB, PFC 11psi the 14psi on the 4th with new mods

 

intake, dp, greddy pullies, exhaust, & m2 ecu @12psi. driven at least 100 miles a week.

 

12 psi with mods in sig.
