How much boost is safe, yet aggressive to run on pump fuel?? I'm running 20 right now. Here's my setup:

Hyperflow FMIC
Xede Computer
Innovate LC-1 Wideband O2
Innovate XD-1 digital display
GT30R Turbo
RNR Tubular Manifold
ARP Head Studs
38mm Tial Wastegate
3" RNR Down Pipe
3" Offroad Pipe
3" Buschur Cat-Back Exhaust
Denso Iridium Plugs
Buschur 680cc Injectors
Walboro 255lph Fuel Pump
HKS 264i/264e Cams
TurboSmart E-Boost Electronic Boost Controller/Gauge
HKS HiperMax Coilovers

 

I am running 24 pounds on good old 93

 

22psi on 91oct

 

What kind of pump fuel do you have access too?

 

thats pretty high, are you running with alcohol/meth??

i spike to 22 on 93.

 

93 is all we have around here

 

I'm running a 21psi spike on 93 octane, but I also don't have a flash yet.

 

no alcohol or meth yet, but with the bigger injectors and a good tune 24 pounds is safe for me.

 

your on a 50 trim kit though right? are you only putting down 327 with it as well ?

 

i think i'll shoot for 22 or so then....now if i can just figure out how to change the setting

 

I ran 23psi w/ my old GT30R and XEDE.

 

I've been as high as 24 with no knock on 93/no meth, but 22 pulls a lot better because of the timing advance.

 

Yes, on a mustang dyno but the tune is conservative right now until I get my meth kit on

 

ive run 27 psi on our 35R on 94 (lucky for us in the northeast) octane sunoco with no knock 11.2 afr peak...

stock head gasket, arps, cams, 35R .63, 880 injectors etc.... utec etc....

but, i will run 25psi on the final tune on pump.

we have seen serious differences depending on the brand of fuels also.... i tend to stock to sunoco or mobil.

also...

we made 372whp on a mustang, 93, 23.5 psi on a 60-1 non ball bearing turbonetics... no motor work aside of supporting mods (no cams etc)

damn low reading dynos! lol...
