Had a wee quick search but couldnt find out any definite answers to whats the best cooling / least lag options when fitting aftermarket alloy rads and intercoolers. Ive got myself a 52mm alloy rad and large front mount, but not sure what layout to use to fit them, and can make alloy brackets to suit both. Im looking as little lag as possible but to keep water temps as low as possible as I plan to do the odd trackday. I was thinking rad mounted vertically directly in front of the alternator, and the intercooler out front, but Im worried about massive lag, using a single T04 turbo, but looking for any advice.................
Cheers in advance.
you aren going to get massive lag.LOL. the differences between different mounting positions and turbo spool up will very minimal.
obviously the shorter the better, however sharp bends of 90* or more can equate to adding something like 7ft of pipe so its swings and round abouts reall.
the best thing to think about is where you thimnk each cooler will get maximum air flow.
i ran large front mount IC in the front bumper with the rad mounted behind it inside the engine bay. i was going to convert to a v mount setup using my exhisting parts but i sold the car.
a v mount will give better air flow to each cooler as it acts like a huge scoop if you weld in pieces of ally down the side to stop any of the air going around the coolers instead of through them.
Cheers lad. Anyone else tried different layouts to confirm any differences? Im only asking as Ive seen pics of some fds with ics horz just in front of the alternator with very short pipework, and others with vertical mounted rads just in front of the alternator, and intake pipework running down each side of the rad to the intercooler out front, hence why Im curious of the different pros and cons.
Grants hit the nail on the head mate....
Its just what you fancy.. You wont notice any difference from either positions
Cheers lads
Ive got the front mount out front lol, and rad infront of alternator with metal plates top and bottom to help air flow direction.
