just asking what peaples views on the the best all round intercoolers are please,the cars chipped,-31 actuater,exhaust and has a piper cam in head off his old engine.used one of the little pace jobs years ago but car got written off and then used one of the first grs full front versions on last rs but had real trouble keeping car cool.so any help and advice would be good as me brothers got his eye on an airtech frontal cooler cheers si

 

GRS. Nothing better.

 

cheers mate

 

Is it charge temps your having issues with, or water temps?

 

I run GRS, was brilliant on the cvh, not used it on the zt yet

 

GRS.

 

it was water temp with the old grs cooler

 

Try cleaning out the rad, and get yourself a 1.3 CVH 82 degree thermostat.

Afraid the higher water temps are a side effect of the cooler working so well.


An alloy rad will help in this situation, if you can stretch to buy one.

 

will get the thermostat thanks for the info and my brothers on about getting an ally rad when gets the cooler and cheers again for the response

 

No bother.

 

think your find an 4x4 cossie is better

 

I had a GRS on my old turbo, seemed to work ok, apart from 2 things - the mounting tabs snapped loads of times and the car overheated like a bitch as the cooler blocked the rad.

The NMS intercooler seems an awesome bit of kit, no idea how much it is though?

 

GRS seems to be very good. as long as you dont mount it like they tell you to!

how the hell the car is supposed to stay cool like that i dont know!!

 

Maybe 2 of them welded together NMS style? But on it's own?


You'd need a reverse crossover pipe too....

 

pretty sure the NMS ones are made from 2wd intercoolers and yes you will need the reverse cross over pipe

 

i had a grs front mount but i sat it rite in the bumper.slightly trimmed the bumper but didnt cut whole thing out.left standard fan on rad.it had nice big gap between intercooler and rad that way to allow air in.had no problems like that

 

Have had GRS and Radtec setups and if anything GRS ran a little hotter. Ran about 30-35 more hp with Radtec as well...But purely for IC would say GRS.

As said though given the choice i would have the NMS jobby, or push the boat out and go with RS500 spec and a removable front panel

 

When you fit an I/C and rad you must have them sandwiched together without a gap in the between them as you are relying on pressure differences to allow the air to move into the engine bay.

Like an injector firing into the inlet manifold, pressure has to be higher the rail side than chamber.

 

GRS is the best Intercooler, in terms of performance and fitment. I've tried others, but none have worked as well.

That said, I might be selling my GRS soon.

 

just to throw a spanner in


i got a modded mitsi evo 7 in mine (wrc spec core, what ever that means)

was done by the pro alloy boys

 

I was just about to say, no ones really rated pro alloy

Is this is a no no then

 

the stuff they do off the shelf is not really up to big boost


had one when they first come out, took it back off qiuite quickly

 

how did you have yours fitted? and what fans? also did you have temp problems?

mine used to run hot once i had the GRS and alloy rad put on. i did have a 82degree thermo too.

or anyone else that had no problems how was yours mounted, fans, etc?

 

The NMS ones are now custom made as far as i know? They aren't 'just' two cossie ones welded together anymore.

They also seem to give good airflow to the rad.

 

again cheers for the ideas and we fitted the grs how the instructions said and the car just overheated at the sight of traffic but other than that couldnt fault it.i think a change of position could be in order if get another grs as we saw a few nice ones at donnington last week that had moved them lower down,and im quite good at overcoming head scratching moments after some of the stuff ive done with my bike ha ha,i will tell my brother what everyone has said and thanks again si
