im talking 93, no injection of any kind?
lets say a fresh rebuilt streetported S4
turbonetics 62-1 with .96 hotside
all the fuel needed, 800 P 1680 S
FMIC and 3 inch piping
E6K and a decent tune?
what would be a realistic SAFE tune?
how much PSI and how much HP?

 

350whp around 15psi depending on the porting should be pretty safe, assuming all your other bases are covered.

 

i plan on having plenty of fuel.
dont know what to use for ignition though? jacobs? MSD?

 

actually I've found the stock ignition after a haltech installation (see adjustable dwell time ) stands up pretty good. Even to compare stock engine/ECU vs. stock engine/haltech, you'll see much less break up up top with the haltech.

 

It's an s4 motor so 8.5:1 compression ratio. He could run more than 15psi safely on 93.

 

I run about 415 on pump, but I use alcohol.

 

my friend made 410 on his FD on straight 93 (AntiVenom7 on here) for maybe 15-20k miles. He popped it when he had a low tank of gas or something and it somehow ran lean.

 

id like 2 MAPS made for my car
1. just pumped gas

2. gas and alcohol

save both maps so that i can switch for track days.

 

a local member made over 400 (407 to be exact) to the wheels on straight 93....no additional injection whatsoever. So 400 wheel, or VERY close to it should be attainable on (93) pump gas.

Good plan on the map saving though

 

Uhh.. Just use a high/low boost switch. Thats what I use.

spring pressure for the street. 24 PSI for the track!!

 

huh, shows what i know about this E6K!
mind sharing how you did this please?

 

I use an Electronic Boost controller. When I dont have race gas in the car, I just use a low boost setting. There is no reason to change the map on the E6K, the specific gravity of C-16 is so similar that you can tune on it for high boost, and be assured your pump settings will only vary by about .1-,.2 points on AFR.

Since the K is load sensing, it only reacts when you tell it too (I.E. how many pounds you are running).

 

i made 430 on pump at 15 psi, stock t2 coils , one msd 6al on the leading. i have an s5 motor, i dont know how far you can push the s4s
