BOOSTD

There is room, however I'am over the 6 cyl WRX sound

Re-attached

Every single turbo car I have seen has oil in the intercooler pipes. I wouldn't stress to much unless there is alot. Oh and btw get the leak fixed at the bottom of the cooler

any more thoughts ? Getting my new system custom made tomorrow morning. It will consist of twin 3" front pipe through 2x3" magic cats and then merge to 3.5" Cat back. I will be asking for the Y pipe to be as slow transitioning as possible....since 2 three inch pipes into a 3.5" would speed flow up in a hurry

bump

HKS GT-RS will make 300rwkw with supporting mods, also look at a GT3071R from www.atpturbo.com (alot of info and dyno charts).

boost is measured at the plenum. boostd is a measurement of restriction, flow is what makes power. The cooler flows the same at less boost

I just finished installing my ARC intercooler. My initial impession was a massive increase in low to midrange and much sharper throttle response. After further investigation I found the car was running significantly lower boost but no loss in power. I put this down to much less restriction from the intercooler....which is what ARC are all about. At .6 bar in first and second the car spins up all 4 and changes lanes by itself. I haven't loaded it up in any other gear as the tuning is all up to sh$T now. I can't wait for another dyno run so I can over lap the two. Conclusion <ARC are GODS> PS this cooler replaced a TRUST item of same thickness

Advan reccommended using Dextron III. I spent big on Transmax Z =(

third gear is the weak link, might as well drive it till it breaks

Not sure if I follow you guys. The ARC cooler kit has twin inlets. The associated piping has to have the BOV return pipe reomoved to fit. (from the two inlet pipes after the AFM's) Also the return BOV plastic pipe behind the intercooler has to be removed as the angle ARC have set the intercooler on is pretty large.(leaning forward)

hmmn I won't think ARC would do it if it caused problems. I'll get the mrs to translate the instructions. Maybe it states Aftermarket are needed. Doesn't look like it in the diagrams tho.

yep, adjustable cam wheels

yep second hand, piping pics i have to get from home.. I do have the instruction manual with it...trying to figure that out atm

pics up, more to come

I have just recieved my ARC intercooler for my R33 GTR. The kit comes with piping and also some solid plugs to fit into the BOV lines. I am not sure if I should be installing after market BOV's or not. Will the Lack of BOV's cause issues?? Or is the a ploy by ARC to increase engine response...from what I can see the twin entry piping will not fit with the BOV return line. Matt ARC.php.jpg

I'll take them, PM sent

yeah and we are not a wrx forum

I know an equal length manifold works very well, however being after the turbine may degrade any substantial gains....

ok NOS is partly o2 in a compressed form which enables more power from say a restrictive intercooler for the same area of oxygen, NOS has a much greater density of o2. When you heat nitrous oxide to about 570 degrees F (~300 C), it splits into oxygen and nitrogen. When it vaporizes, nitrous oxide provides a significant cooling effect on the intake air. When you reduce the intake air temperature, you increase the air's density, and this provides even more oxygen inside the cylinder. This overcums much of the flow restriction and heat related power loss. And since NOS is injected after the intercooler....the size of the intercooler has less effect on max power out put. So as for being pointless and bearing no relevance, that is your veiw. Were I was pointing out that with the assistance of NOS a 10second time with ANY stock cooler would be more feasible.

Handles like a go-cart !

i've seen a R34 with stock SMIC make 278rwkw with NOS lol.....u get the picture

I bet it runs NOS, only way to over come the flow restriction

anyone?

I would disagree, The core on the Just jap cooler looks very good. It uses the same type internal fin structure as the GTR trust items. On the exterior the tubes taper to a finer point rather than a blunt rounded edge to encourage more airflow through the core which is a very good design on a thick core which suffer from starving the radiator from air flow. Very similar to ARC intecooler design. The exterior fins are also fluted to increase cooling.
