@terribleoneprimopro

i dont think that to be accurate.....

my idle afrs sit at 15:1 as well as my cruise tables, under boost i am at 11.8.

my fuel system is rather conservative using stock 550cc primary with 2000cc secondarys and the IDC is at 40-50% at 20psi on a 35R.

timing is rather aggressive tho since i wanted my egt's to be around 1500*F under boost, but it gave great response and good torque

@mexinuggetsanyone

your ignorance is exactly the negativity that the rotary doesnt need.

my FD has been pushing 25psi on a 35R with 1.0 a/r turbine for the last 5 years or about 40k miles on the original, stock motor with 105k miles.

dont be an idiot.

the success and reliabilty of any engine is in how it is tuned. and i had mine tuned by well known rotary tuners.

nice

Depending on airflow and timing these cars require ALOT of fuel for more power.

Also take into account the bnr compressor with stock clipped hotside flows more air at lower boost than the stock turbo. Stock turbo STRUGGLES to make 250hp at 18psi........

[mexinuggetsanyone]

yeah you can push more boost in a rotary engine... then expect to rebuild it within the next two years and oh by the way that's only $3500... maybe he's running 7psi because he wants his car for a while?! and either way a better turbo, exhaust and tuned set up can make way more power on less psi. better exhaust flow is better then just more boost.

@iamxeddiex well kinda. . . but i meant like different apex seals.

Wankel!

[iamxeddiex]

@ 255 it better not have a port job.

[iamxeddiex]

you mean a port job.

ROTARY FTW!

S4 PRIDE!

[buhrrito]

is your S4 block stock? or do you have like a rebuild internal motor?

[myersprostatus]

why are you only running 7 pounds? this baby could fly
