Outer Limits 4x4 Board

what does everyone think of these? the price is unbelieveable but i question the quailty over an off the shlf kit 3 or 4 times more expensive.

has anyone bought one?

For an intercooler to work properly it must have about 1psi pressure drop otherwise there won't be enough surface contact to cool the air. That kit claims 0.05psi drop which won't work!

One of those thats hard to say I have just built my own that has a 2% pressure drop but the style of cores is very different in mine.

At the price it looks just too good and the pump does not look up to the job either.

With a low pressure drop across the unit you have to wonder how much surface area is available and what's the temperature drop across the unit ?

And the pump doesn't look much to me either. The Bosch ones PWR and others use are designed for hot water and use magnetically driven impellers so there is no shaft seal to leak or wear out.

I have one of those, but XSPower brand. Same design, the measurements on mine match the "600hp model".
I think their power ratings are a little optimistic, probably based on a big capacity V8 with minimal boost.
If like me you're running more boost then their ratings don't mean squat.

I haven't hooked mine up yet. Shame on me.

Regarding pressure drop, they haven't mentioned what flowrate they measured that at, pressure drop squares with flow. 0.05 psi drop at very low flow is possible, but I
m expecting to get a lot more than that in use.

So take their numbers and claims with a few grains of salt, but the product might be okay. That design has been used on many race vehicles so it must be a viable option.

i would understand the design/dimensions would work. but its the quality of the materials and build that i guess would be in question. it states he lives in brisbane so i wonder if he will let me come look at them?
