id try it
although iv read all the remarks of it and agree that it'll probably feel ****, but people shouldnt live through other peoples experiences, lessons need to be learned..atleast by trying it and finding out for himself, he might have learned not to cut corners on the next purchase
who knows it might even be adequate for his car

True, but these forums are here so people dont have to learnt the hard way and find out for themselves, There is alot of experience on here so use it, take advantage. Becuase some mistakes are expensive, and a £400 FMIC is not something you want to get wrong.......
yeah and if it hadnt already been bought then I'd agree, i know that I wouldnt take the plunge and buy one after reading all the stuff about em, but as he's already bought it, i just think he might aswell just try it out

I dont see how ignoring others personal experience of this to see for himself how much pressure drop across the core he gets is going to help in other than experiencing some how to fit it time... ready for redoing it and getting one on which actually works properly.
Detuning your car and paying money for it and taking time to fit all of which could be avoided.
You ever run a GRS?
no i havent, but nor have more than half the people who slate it
im not saying that you or mike an addo are wrong...far far from it infact, as stated i trust the views of those who have tried the GRS, and wouldnt buy one myself
but i also havent run a laguna fmic, nor have the majority of this forum yet look at how much flak that takes, and yet there are some people happy with it and without proof that its less effective
im not trying to start a huge discussion or telling anyone to ignore any of the valuable information...but theres only one way to learn something for yourself, its not like it'll waste a whole day to fit it... he could prob fit it, test it, decide he doesnt like it and remove it from his car and stick it on ebay in a day
All im trying to get across is that while he has it, he might aswell just try it out for himself, if he doesnt want to then fair enough, otherwise what was he point ordering one in ther first place, whats the point doing anything to the cars, we all know its a waste of time and money in the long run anyway

at the end of the day its his choice as to whether he want to waste his time potentially with what he's bought.
I have no opinions on laguna cos I have no experience of it... but I have seen GRS, rejected it on sight and chatted with the man who made it directly. He wanted me to try it, but it was never going to flow adequately. It did cool however, but the pressure loss was very undesireable.
AM's initial core offering did'nt work well enough IMHO either, and that progressed and developed into something that did. (with stage 2 offering as an upgrade, and better end tank design on stage 1)
His choice..
he has to put the effort in after all.
In his shoes' I would bother.

As Bill said it takes alot of trial and error which unfortunatly for us we went through so you guys on the forum get the benefit of the knowledge and dont have to.
Our GRS Cores lost huge Boost around 5-7psi. We got around this by converting them to single pass and new pipe work which brought back the boost but core design and pipework design was poor.
from here we developed our own core which again was a big improvement on the Modded GRS, but due to end tank design didnt have enough Dwell time in core. Especially fitted to something like Bills IHI @ the time. So again it was back to drawing board changing end tank design and pipework.
Suppose the one thing to consider was that the Modded GRS singlepass core we done did work okfor regular chipped cars, as did our first core on chipped K03s. But as we aimed for suitability and max performance i.e. ihi territory it pushed us to continue developing the core with Bills feedback to its latest stage on both stage 1 and stage 2 cores with different end tank designs vs size to get best out of it on big bhp applications
What im trying to get at is We went through alot of hassle & money to get it right. Granted we learnt alot through the experience of buying the GRS but would I do it again????? Like Feck..... Its the old phrase:
"Do it once, Do it Right"

Basically a FMIC shouldnt go there. and requires alot of work to get it there. No More work than our own core but you have to ask it it worth the work to get the GRS there, My answer would be No from personal Experience.
When I first fitted it it took the best part of a day and a half, Addo was the same, partly due to limited knowledge and poor instructions. Although I could prolly do it in a few hrs now... just gotta look at the bumper and it jumps off as does most of the engine bay stuff case its been of so often
Anyway its alot of work and not straight forward
Single pass, dual core, dwell time! Can someone please explain, as i'd like to learn.
I was tempted by a GRS, but after reading peoples experiences with them, i opted for the forge one, purely because of a group buy discount, and excellent customer service. If i was to buy a FMIC again, it would be between the Forge, and the AM one. One the basis that both have good proven results, and look good!

Single Pass is when the inlet is on one side of the core and outlet on the other.... Like forge & our own.... This is most efficient way for an intercooler to flow
Dual Pass (Like GRS) is where the inlet and outlet are on the same end of the fmic, i.e. inlet at top of passenger side and outlet at bottom of passenger side. This means the air has to flow through the core twice, i.e. through top half of the core, into other end tank, through bottom half of the core then out through outlet. This cause pressure loss
Dwell time is the amount of time air stays in the core.... This is where you have to be careful. For example too long and you have pressure loss, this is usually the case on badly designed cores or cores that are oversized for the application. If its too fast like I original core it throttles and goes through so fast it doesnt cool air down enough or that it doesnt allow equal filling of the core and only uses x amount of rails due to speed. this usually means system is efficient air flow but not always good for High Boost applications so this is why we modified the design of the end tanks to slow the air down and distribute the air evenly through the core
Hope that makes sense

yeah myself and adam were the first to say, after all we had him mod the GRS core to our spec, We designed and had new pipework fabricated, then drove to him to get him to mod the existing core to our spec. Fitted pipework and went on our way. A Bit of guess work but it worked out at the time
