Max boost level 16g

[R-U-QUIKR]

I was curious to know if anybody knows what the max boost is before it would be to much on stock fuel trim with a evo 3 16g turbo. I know it is around 15psi on the t-25 but because of the cfm difference I'm not sure. Thanks.

I wouldnt try to run anymore than that 15 psi until you atleast do a fuel pump upgrade.

with the proper fuel upgrades i have efficently ran 23 psi with a smic

maybe with an upgraded smic but no way with a stock sidemount

 

[fooked]

Yeah 23 sounds a little high with a stock SMIC.

I'm running bigger injectors, fuel pump, HRC FMIC, and a Big 16 set @ 22psi. I would say that's probably gettting close to the end of the efficiency range for a 16g on pump gas.

A little? I have all supporting mods and couldn't get above 19psi on the stock sidemount. He must have a constant spray of liquid nitrogen on his IC all the time. Either that or he lives at the South Pole.

with a front mount and larger injectors/afc combo, 25psi has been seen, shit you can throw 28 at it but not for long.

yeah with a pump and 550's with my 16g i run 24-25psi with a stock smic all day long. well with stronger pistons too. i didnt say it was good, but i get away with it ..

Yeah, me too. But now that the south FL weather is finally starting to cool off a little, it's not quite as bad.

 

[R-U-QUIKR]

Soo... Is anybody actually going to answer the question i asked? Max boost on stock IC and Fuel trim.

theres your answer

 

[doug]

Plus, with no engine/fuel management, you're gonna probably hit fuel cut even at 15 PSI.

 

[btracer]

hmm... i have stock smic and supporting mods but my b16g holds 20psi pretty good. (pump)

Do you guys actually do any time of logging when running 20-23psi through a stock sidemount intercooler? Mine would heatsoak after about 10 seconds of 17-18psi. I would bet your cars are pulling timing like no other and would run faster at a lower boost level.

 

[StyleElements]

maybe hes right guys .. should prolly do something about that .. i would but i wasted to much money on paying dean mason to screw up my trans. intercoolers are so much money :thumbdown but i guess it needs to be done

Exactly

At 19 mine was, so I dropped it back to 17 and now that the weather is cooler - the car runs much smoother, no more timing dips and it feels just as fast as the 19 setting on its best runs.

i have AFCII and logger and dont pull much timing at all at 20lbs. i raced last saturday and everything was fine. though the temp was around low 40* and i never hold 20psi for longer than 10 seconds.

 

[playboy1884]

mine is pretty stock , i have a fuel pump evo3 16 etc , and i run 21 w/o any problems i ran 25 one time , for about 5 mins didnt do shit , no joke

i concur with this guy.

 

[doug]

i run 21 w/o any problems

That's just it-- you don't KNOW if you're having any problems or not since, according to your profile, you have no logging or fuel management tools. It may *feel* fine, but you may still be getting some timing pulled because of knock.

 

[Fakie]

I agree. my car felt "fine" runnin 17psi...till I hooked the logger up and found out I was getting 22 counts of knock :thumbdown
