Well I have plans for a full turbo and standalone upgrade not to far down the road, but Im curious what I can do to make some more power now. Here is what I have currentlly.

720cc secondaries
Koyo
AVC-R
SAFC (not really tuned right now)
HKS intake
2.5" turbo back

I am just curious what I could do to make maybe in the 280 range. Maybe I am forgetting a few things, but I am not seeing how I can really make more power without upgrading the turbo, which would result in the standalone. Basically I am wanting to make as much SAFE power as possible, before I have to go the standalone route. I liked the hybrid idea, but it seems as thought the standalone would still be needed. Any advice from you guys running around that kinda power would be great. Thanks in advance!!!

 

i need to know how to tune the safc too...

 

That stock turbo will most likely not make 280. If anyone has made 280 on a stocker, I dont know about it.

They hybrids like standalones because I think you need to run a little more advance in order to make efficient use of a hybrid.

 

Get a wideband, install wideband on car, determine target boost, creep up on target boost in 1 psi increments while watching AFRs on Wideband, add/subtract fuel as needed to maintain mid to low 11s AFR with the SAFC, once target boost is achieved, car = tuned.

 

Then install an EGT gauge & tune the timing.

 

Bah! who needs EGT? I just prefer not to know...

 

the previous owner of my vert made 270on a stock turbo @7psi. S4 turbo, S4 engine.

EMS, FMIC, etc.... but stock turbo.

(just fyi!! (not trying to prove anything, just putting the info out there))

 

Also, you might want to get a new fuel pump also.

Just FYI.

 

7psi...that seems..highly unlikely. When people struggle for 260's at 12-13psi?

I'd LOVE to see a dyno graph of that, especially on S4 engine + turbo..

I'd bow down to whoever tuned that thing.
