I have a 97 LS, the whole bottom end is built 9:1 . I have 440cc rc's, a 255 lph fuel pump, fuel regulater, and a FMU. I was wondering what is the most boost i can run on 94 octane and maybe a octane booster. I was told 15 Psi. If any one has any info please let me know.
thanks

I forgot the most important i also have a Apexi Afc

thanks

 

It's really not a good idea to have that pump with an FMU. they cant take the pressure.

 

what do you mean you shoudn't use a fuel pump with a FMU? doesn't DRAG kits come with FMU and fuel pump though?

 

He means that /particular/ pump.

 

I suggest you check this out http://www.hondata.com/tech.html
That should help you determine that 15 psi on the stock ecu is very hard to achieve. The most restrictive part on the engine is the map sensor. 3 bar map sensor can cure all your problems.
