How much boost

[1fast97gsx]

... could I run with a 16g on 660s with safc and 255 fuel pump on a supra smic? I want to keep the sleeper look but I still want to be able to basically max out the turbo ... thanks.

is this a small or big 16g? if its a small 16g you can get away with 18psi on pump gas. on race gas you are good for over 20

yea its just a small 16g ported. Hmm 18 psi seems good ... I have it set at 17 right now but I still have that stock pos intercooler.

If you tune the car right and log it and stuff you possibly could get away with 20psi on pump as long as its 93 octane. I ran 20psi on 93

I run 20 psi on my 16g all day with 50 lb fuel fuel pressure, walbro 255, safc, 550s and 93.. no probs at all..

with what intercooler? I have the stock one still and anything over 17 psi I start knocking a little. I don't have aftermarket fpr either tho...

 

[Wobble]

the 500 dollar dejon tool one.

Not 20psi on stock IC.. didnt know you were still on the stocker. Yea nothing above 17psi id say. Get a supra sidemount or somthing. Then jack it up to 20psi

at 20psi on a supra SMIC, isn't it likely to hit fuelcut due to the increase air flow?

 

[1fast97gsx]

I'm not really worried about fuel cut ... more so timing advance /knock

 

[Wobble]

youl get fuel cut via MAS ovverun with any intercooler/setup if your not running bigger injectors so you can tell your MAS its seeing less air..

thats a wonderful feeling BTW... hitting fuel cut.. make ya crap yer pants the first time..
