Eri S2K, your setup looks great. I'm surprised more people don't use a FMIC for the same reasons turbo guys don't use air/water setups. I'm not saying one is superior to another, however though there is more piping in FMICs they don't have the heat exchanger, pump, and/or reservoir to have to deal with and appear (at least superficially) simpler to deal with.

 

Thanks Bro! jejej

 

interesting... i look forward to your readings next summer

 

quick question. If you run a air/air intercooler set up with ctsc or vortech kit. Will there any boost lost ? for example if the ctsc come standard 5.5psi. Will it still boost 5.5psi with a air/air intercooler set up instead of the aftercooler ?

 

On a dyno pull where you are doing a steady run up to redline in a higher gear like 4th, no, you won't lose much boost, if any at all. However, in the real world where you are going through the gears quickly, I believe you will not see max boost as you did with the stock setup. Every time you change gears and close the throttle, the BOV will release some intake pressure. Also, first gear goes by so fast, that the blower will have a more difficult time compressing the larger air volume in the same amount of time. By comparison to a car on a dyno, 2nd and 3rd gears will go by pretty fast also since you are starting off at or near VTEC rpm after the change.

This is not unlike those who started off with a Comptech without an intercooler and then adding an intercooler. The extra volume of the intercooler and accompanying hoses and piping dropped the boost pressure by about 1/2 to 1 psi. Owners were compelled to buy the smaller pulley to get that pressure back. As huge additional area like that of an air/air intercooler would create a bigger pressure loss.

 

i had 4psi boost drop when i tried it

had 2.5inch piping, revhard IC

 

I see, I should try to run a the CTSC with a intercooler set up. I want to see if there any power lost.


^ how did you lose 4.5 lbs omg thats alot. I never heard of a turbo set up losing boost like that.

 

I have the 10psi SOS Pulley and at the Dyno the Boost Gauge and the Boost signal in the Dyno Readys 10psi EXACTLY!

So i dont have any Boost loss

 

Eri, as I've attempted to explain, doing this on a dyno is not indicative of what goes on in street driving when you are going through the gears. Also, the pulley may be marketed as a "10 lb pulley" for the application you used it for. Unless you did a before and after run, you really don't know what kind of psi it would have achieved (with and without FMIC). For all you know, it could boost 12 to 14 lbs without the front mount. Did you do a "before" run and measured the boost pressure with the same pulley?
History and documented reports indicate a pressure drop anytime the intake volume is increased like when an intercooler is added or an intercooler is increased in size.
