450hp?

[Supraboy89]

just wanting to know if anybody has achieved 450 horsepower with a SAFC on pump gas.

Go here. Control F and type "safc". Tekdeus got over 500 whp.

With the Lex AFM and 550s looks like 450 is plenty possible with a bigger turbo.

I'm hoping to do this without an afc. I want to do it with just lex/560s. It won't stay like that though of course.

allright well when i tune with mine the highest hp ive hit is 375hp at 18psi and 387hp at 20psi with 11.7 to 11.3afr across the rpm range and cant seem to pull anymore hp out of it. i have all the mods to get 450hp but cant seem to get there. the only thing stock is my turbo mani and intake mani and throttle body and engine internals.

What size turbo are you running? Can you post the dyno sheet, and does it include afr graph?

A bigger turbo will yeld higher numbers with your set up. Do you have a fuel pressure regulator?

A mod list would be nice. Only thing I see is you're pushing a ct26 60-1 to 20 PSI and only getting 387.

i made 448 on a 1jz with a bw 83-75 (60mm) with SAFC II and adjustable fuel pressure reg. I think you need more turbo to hit 450 on pump gas.

Well the guys at precision turbo said the 57/58 was good for 600+

Website says 540. Thats probably at 25 psi or high without seeing a compressor map.
