Yeah next to no lag at all due to the short pipe run.
Basically there's a rad / cooler at front of car as well as the normal rad but the one to the charge cooler is much smaller.
The water continuously flows through rad into the bit you see under the bonnet which is basically a heat exchanger so you have the cooler mix cooled by air flowing through the rad which then cools the charge air again in the heat exchanger.

Cool charge temps will make the car faster and is much better for the engine as your less likely to suffer a melt down on pistons so when cars racing on track it's paramount if you want the engine to last any length of time.

Also the car we just sold to tucker on this forum has a pace charge cooler fitted with a 3071 turbo, absolutely zero lag and very responsive car, you would not get that response from your average fmic kit

What's the max bhp you think is safe with your charge cooler set up

Well if possible to make 900bhp out of one of these engines then it would be good enough for that I'm sure.

The rasheen could be running up to 650 and I've no doubts whatsoever that it will be fine

Charge cooler kits are very expensive though been looking ....

Yep there not cheap
The pace one fitted to car I just sold the guy I bought it from had paid over 1250 for that.

The funny thing is when I had the one that's fitted to my car now up for sale a couple years ago I think I advertised it at 650 then dropped it to 550 and no one wanted it but soon as it was fitted to my car all of a sudden everyone wanted it but then I thought don't want to flog it now lol

Seems out my budget lol.... Anyway back to my original question front mount or top mount!

Would I need a front mount for mapping?

I don't think there is a right or wrong answer there mate, it all boils down to personal preference. You won't 'need' a front mount for mapping but if your going to go with a front mount then obviously you may aswell get it fitted before hand.

Mr b. you said something about charge rates.. What do you mean by this pal

Charge temps, basically if you measure air temp before & after the intercooler you will get idea of it capability & limits, not many tuners do this extensively as lazy at R&D but not so lazy when come to the banter as they don't make money not selling you parts.
I would run up to 400hp on a ARC or re-cored top mount without concerns  in uk/europe type climate for road & light track use..
Front mount was a fad & turned into an easy tuner sale & main reason car owner got it was for looks rather than the technical need/benefit.
Basically use only what needed for you power goals & spend money wisely, sure BIG power cars & extreme track use or hot climates such as asia pacific means decent front mount  probably needed but for most peoples power & usage  the top mount will be better option.

As Bob says charge coolers are good & do lend themselves well to the GTiRs available space. Efficiency is very high & they can have benefit of short neat charge pipe runs but disadvantage is cost, weight & complexity.
Fit what you need for your build power & usage type, and that is where most people go wrong & budget is gone or drive-ability/reliability ruined is the result.

don't think the charge cooler weighs any more than a 4'' fmic setup tbh as the rad is far smaller in every dimension, the pumps being plastic are very light and the exchanger weighs no more than 3kg say 4kg with fluid added so all in all around the same weight as an ebay jobbie maybe less.

but as said, its total overkill for a car running the usual 3-400hp when a tmic or half descent fmic will do the trick

Weigh in all components/fluid if you got it off vehicle as interesting seeing actual figures on that to some common intercooler kits.
For there heat exchange capability you couldn't complain at some extra weight.
Do remember seeing your one advertised & surprised didn't go as price was cheap really & a great bit of kit for high power track car.

Best thing you can stick in your charge cooler tank is some ice cubes Bob :-)
Good excuse for a mini fridge in back of rasheen :-P
Water & methanol injection is quite good & seriously helps lower cylinder temps but once again quite expensive, needs good ecu control for max benefit, is complex plus needs topping up frequently ...

Ok i touched my tmic piping after 15 min driving it was burning hot..Think i decided going to go for fmic can anyone reccomend a decent one short as possible run?

The pace front mount kits have a relatively short pipe run but they are not cheap

Is it possible to buy the intercooler and do custom pipework? Would that save cost and maintain efficiency

I suppose you could do that if you can fabricate your own pipe work or know someone who can do it.

I would like to get a custom pipe run made up for my front mount because it has about 5 miles of pipe work to it Laughing

How much power you going for, I've used top mount for 15 years, original top mount at around 3 years & 320hp & ARC for the rest & slightly more boost. I checked my charge temps - they decent enough. Only extras I done was thermal shielding under top mount to reduce heat soak & water injection as on standard pistons. engine still good fingers crossed, top mounts do work but go front mount if that what feels best for you.
Custom is possible but main issue is for good pipe run rad &/or slam panel is in the way so can get costly unless very hands on yourself.
also review your budget if not endless as spending too much in not needed areas tends to be a project killer.

Don't forget the Radtech one which has short pipe runs.
http://radtec.co.uk/products/299/Pulsar-GTIR-Intercooler-Kit.htm

When I first got my car it had a front mount and the water rad had been dropped by about 3" and the inter pipes taken over the top. Quite good short pipe runs but they had cut out most of the bottom cross bar to make it fit..  Neutral

if you want a fmic kit with short pipe run ive got one you can have for £120
I cant remember how the pipes ran on it as was taken off a while back now but everythings there.
you can adapt pipes yourself as its not hard if you have some couplers.
you can run them under slam panel on inside of headlights that's what I did with my old fmic kit which shortened the pipe run drastically
pm me if you want it
