What is a safe boost level

 

[Guest]

a little bit less then fuel cut off

 

[Guest]

where's that

 

[Guest]

~ 12psi Youll know it when it happens.

Itll feel like a really harsh rev limiter

 

[Guest]

what kind of numbers can he expect on a dyno and at the track (Stock wheel and tire)

 

[Guest]

Hard to say...

Maybe 260-275 rwhp if tuned at 12 psi

Maybe mid-low 14 seconds if you drive it like a champ

 

[Guest]

BTW what cut defencer would you use

 

[Guest]

theres only one that I know of that is strictly an FCD and thats the HKS, I think our cars use the code K...

Its not smart to do that mod unless you know what youre doing.

If you boost much higher then 12-15 on stock fuel, stock HG, etc youre asking for problems.

Get an AFC and do a little fuel system work before you even think about an FCD

 

[Guest]

I have no experience with supras but I have the hang of the tuning concept I just need advise on what needs to improved or adressed to get around 350 hp with daily driver confidence

Don't use the FCD unless you want to rebuild REAL soon. It is aweful easy to run lean with one of those. Get a real computer like s-afc II or emanage and do it right with some more fuel and air.

 

[Guest]

so the afc tricks the afm into thinking the boost is not too high and at the same time allows you to give the higher boost level that you are really runing more fuel to cool everything down a bit right

Your friend needs a combination of things to get past FCO. An AFM based fuel computer like the S-AFC or S-AFR cannot give you higher boost and run more fuel. The only piggybacks that can do that is the e-Manage and the discontinued VPC/FCON combo. The easiest way to get more boost safely is the Lexus/550 mod (use the search feature for more detail) combined with a fuel computer for fine tuning.

Simply slapping on an FCD on a 7m is a quick way to kill the motor.
