interesting debate.... my current fave kits are the 500/550 kits (not available in the usa) and the g-power kit... 345 Tq at the wheels the wheels though?? nahhhhhhh cant believe it!!

Re the intercooling, a proper FMIC air to air will always be superior, one of the best reasons is a simple recovery time, heat up the air to air set-up, and it'll recover far faster and get temps down quicker, air-water is great up-to a point but once that water heats up.... im willing to bet 100 bucks a track session with a 500-550 inter-cooled car with its very large intercooler will show lower AITs than a similar water-based setup.

when i look to rally based teams, mitsubishi, subaru, citroen, they all place huge damands on their AIT cooling systems and choose air-air, then for me, the latest high tech supercar the gtr, comes with air-air.... even when bumped upto 1500hp, they still use air-air.... this says alot imo!! its soooo flexible as well... bigger pipework, bigger core, bigger endtanks, you can really tweak an air -air setup...

the VF/gpower manifold has cores inside it.... this WILL be a restriction theirs no way around it....

In any instance where a proper sized fmic can be used, id take that option... but they do have their pitfalls as well imo.......boost losses, complex pipework routing, maybe heavier??? not to sure on that one.

i suppose really their is no wrong and right way... but for me, fmic works and is tried and tested....

btw think my car will be the first 550 spec z4m on here maybe?? i WISH g-power offered an upgrade path.... the Tq rich asa unit just makes me want it!!!
