yeah i spoke to him, unfortunately i'm not rich enough to own a mk2 FRS just a lowly mk1
dunno if they do a cooler for that

im not allowed to drive it if theres a chance of rain 
the cooling system is soo good it takes a lot longer for the fans to switch on and thats with an uprated fan switch from MSD. car is yet to be live mapped need a dash 34 actuater.i will have to get some pics up on my own thread

Got my car back from Spec-R after installation of one of their new 'bar & plate' intercoolers, fuck me what a difference. Took the car back to Mark @ M.A. Developments to adjust the fueling and he has managed to get the map back to the original settings from the last dyno (677bhp on pump fuel), he managed to get six degrees back in that he removed when the engine was re-installed as the intercooler that was in the car before was strangling it. The charge air temps when mapping were unbelievable, on one 178mph mapping run the increase over ambient was just 10 degrees c, where Mark would normally see 20-25 degrees c if not more, averaging at just 7 degrees over the mapping runs on the day. The difference is like night and day compared to how the car drove before. It drives like an aspirated engine off boost and spool up is superb.
Here's some pics showing the intercooer/pre-rad and the other goodies:
This is the same intercooler set up as mine, only it's a polished for one of Petes gay customers, think his name is James (Space_hopper).
Mid install

This pic shows the pattern strut brace in place as mine wasn't polished in time
and finally the man reponsible for making my car how Mark intended it to be
a truly gifted engineer
For those of you who don't know my car (Brunters 2004):
I'll leave it to Mark to put up the temp details from the intercooler

This is the best intercooler I have ever tested through out the testing the max increase in inlet temp was 10c at the end on a 30mph run to 178mph,
It was running 2.6bar on a GT35 and the other runs to 150mph we saw 5 to 7c max increase I am stunned at how well they work.
Flow trough the intercooler is improved also due to the entrance in to it being much better as its not hitting a dead stop entrance to the intercooler on the current 500intercoolers I can see a lot of copies coming out in the near future.

bar and plate has always been the way to go. Most cores out there rare just radiator cores. My S2 uses 2 2wd cores and that is incredible.

hmmmmmmmmmmmmmm. How frustrating that it is so much money. 
Wonder if i would see the magic 500bhp using one?
6 degrees advance is a fair bit. Must be something about 6 degree's and cossies. 6 degree beam, 6 degree's ignition advance

pinched from another forum, showing various core designs. Typical cheap egay ones can clearly be seen to be shite. Although often they work ok simply due to being oversized.
material quality, air /fin density
Precision Bar and plate
HKS tube and fin
Ebay B&P (note the relatively low fin density, no staggering of the fins, and little done to encourage vortices to maximize heat transfer):
outside fin design
precision core
Precision (notice the density and the slits in the fins where the excess metal is canted outward into the flow):
Garret Core
HKS (again, lots of slits and they are canted into the airflow):
Ebay (harder to see but the fin density on the outside is less and, while the fins do have slits, they are not canted into the airflow -good for letting air get to the radiator though!):

mark would this type of intercooler have such a large impact on cars running between 400 to 500 bhp

my own core, although entire unit is pretty large, 115mm thick. Not sure why the two dont appear to line up, although external fins can be seen clearly trhough

Yanks tend to favour the bottom style of cooler here.
"Vertical flow inside the APS intercooler is by far the optimum configuration given the space considerations that must be accounted for in the front of the vehicle. This solves the huge air flow restriction problems that horizontal flow cores experience particularly at high power levels.
"The horizontal flow configuration shown above forces the charge air to flow through very few internal intercooler passages. In addition, each internal passage is very long, causing further restriction to charge air flow - resulting in a high pressure drop. In other words, the long route with few passages"
"The vertical flow configuration as specified by APS spreads the charge air flow evenly over a far greater number of internal passages and results in significantly less restriction. The path length of each internal passage is also shorter, further improving air flow over a horizontal design. The net effect is a short route with many passages resulting in a massive charge air reduction but with improved air flow."

Think the gain that Ade had was down to the flow of the end fitments and nit directly a gain from the core. If you have a intercooler made for the car and lined up trottle body it should be far better.
And before people start knocking Pro Alloy yes l did have a couple of problems with intercooler on Yum but they did get there in the end and if l ever desided to get back to this moddifing lark again l would use Pro Alloy
I'm sure it is very hard to do a test of 2 intercooler because of conditions ect ect .
Now I better go before the linch mob get me!!!

dave your wrong it has alot to do with the core as well as end tank design. pete has put a lot of work into both areas

Would love to see a back to back test maybe fast ford could make it happen and all the guys that make intercoolers could supply them a use a Cossie maybe ades l would give my day up to help out changing the intercoolers

True !!!!
I purchased the first 2 cores myself as they were the correct size to get near 100% flow on mine & another 800bhp Cossie in construction. Pete then used the maximum envolope in my car to design this new series of coolers.

spoke to pete and arranged to have a chat with him at ford fair about this
good thread. if only we could use bowmans on our cars....work a treat here
inlet temps 220 deg.....outlet temps 50deg!

I have tested the vertical bar and plate and this was 8inchs tall on a evo and 24inchs wide from mem and at this size on the evo it was found to be to short to work in my words it was crap, So unless it was made taller I would not go this route.

My testing has proved to be better than the last intercooler Ade had on his,
The improvement in cooling is down to the type of core we have used and the way we top feed as it helps with the flow into and through the core.
