Rapid Or Process West ?

[Bomber]

To be fair, the first PWR stepped was poo. The tanks were redesigned and the current version came out January 2011.

Kev has for the record stated he'll chop the top of one of his stage 2 coolers to make it fit and it would still outflow the PWR. Given their is demand for a 'no trim' cooler, I'd love to see another option in the market. Some would not like the look of it not going past the bar (like the stock one) but if it peforms, you'd be getter more air to the radiator.

There's alot of techical differences between all these kits, obviously prices vary, as does "to chop or not" but poeple are also overlooking some very important facts...

I wont crap on and make it look like a lame sales pitch, but please consider and think about your ultimate goals and what you want from the car.

When I first set out designing the V1 intercooler kit, I considered a small thin core , like the F6 unit, but after some testing of the factor G6ET / XR6T intercooler, it was found that flow and cooling wasnt too bad, nothing great but enough for resonable power due to its good design and well laid out piping. The F6 cooler is better again due to its larger core/ end tanks, so my decision was not to try to make something small and easy to slip in, but make something that was priced well, would suit entry level budget but also handle the higher 600kw end of the market.

My view was why sell something marginally better than factory when for the same basic manufacturing costs we can produce a product that will support a huge power increase and gives the customer future growth for bigger power.

With the V1 kit you get the large cooler with 3inch inlet and outlets, no others at this price range have this size, the cold side piping is 3inch and goes directly to the throttle body eliminating the plastic elbow, again no other kits in this price range have this, the hot side and cold side are designed to fit my battery relocation kit & plazmaman relo kit, a few of the other kits wont allow for battery relo kits so check these factors if your thinking of upgrading at a later point.

Same deal with the my 4inch and 3.5inch short intake & airbox kits for the drivers side, a few kits wont suit these, though Plaz & PW will as they have the same upgrad-ablility.

On the upside I have designed piping adapter kits to suit some of the other intercooler & piping kits to use my battery relocation and 4inch & 3.5inch intake / airbox systems, plus the alloy Elbow replacment for those who have cracked factory plastic Elbows.

So best to compare apples with apples and make an informed & educated decision, rather than cheapest or shinniest or what ever.

Cheers

Chris what happen to your center fed cooler? No good?

Think the problem with the FG's is you can't get the width you can on older models, VL's or Jap cars. That's why they have to be so tall. Could be wrong.

What were the differences? Better numbers or just feel?

28rwkw from a rapid to a PW Stage 3 and Inlet air temps where much lower on back to back runs. 9-10 degrees increase with back to back runs for the rapid and 3-4 degrees increase with the PW 3

im pretty sure your right dillz.

my mates 31 skyline and a mates vl all had wide coolers, not tall at all!

taller isnt always better if the air is mostly going through the lower half where the end tanks are....that's why guys with rb30s and 600x300 coolers can push 400kw with gt35s easy as

Upan1c used to have a 600x300x76 cooler on his car when it used to make 370

that's a good reason to have asymmetrical end tanks

that's a bit more than your tuner told me, but you did go from my stage 1 cooler to PW stage 3 cooler , so for the extra $$$$$ you'd want a power increase and temp drop... then again if you fitted a Plaz cooler you'd make more power again, but the kid doesnt like them either

Like I said, compare Apples with Apples.

On the topic of 600x300 coolers, the first BA to run a 9 sec quarter used a cheap Chinese 600x300... If that matters or not isn't an issue, but there's way too much fluff and useless data surrounding intercoolers, go to the drags and see what cars are performing and what's cars arnt... A lot of guys there with big dollars spent and cars not going anywhere near as fast as they could be.
