which is the best one to buy?


have they been back to back tested?


just seen radtec do a new 60 mm deep core, anyone used this yet?

 

pro alloy one the back to back test in performance ford.

would go for that or genuine 500 IMO.

 

The Radtec one had the best temperature drops in the PF test but the Pro-alloy looks more bling.

Both well made but the Pro-alloy one is more finished.

I'd go with Pro-Alloy or Radtec.
No real difference in performance and which one just depends how bufty you are and how much you care one is sub Ł300 the other is Ł400.

I paid Ł260 for my brand new Radtec RS500 cooler, but that was cheap as I bought two

 

was hoping they would come out on top


thanks

 

ive got a radtec one and ive never had any probs with it

 

The only test done was sep 04 PF.

AH fabrications and Rad tech come top on the cooling side, but the pro alloy is a more of a show piece (polished for looks) and had good temps too, so come top.

all Ave temp's in that PF test were on a T4 460-500 bhp car, done from 40 - 100mph flat out. on 3 runs per intercooler

AH Fabs = 104oC ave drop, with ambient 17oC, b4 inter ave 131oC,after 27oC ave.
Radtech = 104oC ave drop, with ambient 19oC, B4 inter ave 138oC,After 34oC ave.
Proalloy = 99oC ave drop, with ambient 18oC, B4 inter ave 127oC, After 28oC ave.
Pace prototype = 93oC ave drop, with ambient 20oC, B4 inter ave 121oC, after 28oC ave.
Std RS500 = 77oC ave drop, with ambients 21oC, B4 inter ave 111oC, after 28oC ave. on the rs500 test i took ave from 2 runs, as the 3rd has a printing error.

on my fiecos i dont notice ambients do much to peak ACT's, not 3-5oC ambient difference any how, but cooler the better.

The test was too rough, as only tested them up to 100 mph,

as on my cossie my ACT's dont reach peak to at least 150mph if more on its first run, but do a bk to bk test (not letting nothing cool) peaks about 130mph.


as if i run the test it would be done on a high boost (35psi) 450-600 bhp car, where the pre inter temps are high in the first place.

The test would then be done, @ a test run way, where top speed could be achieved.
And the done bk to bk tests on each inter, and i would record
peak ACT's before and after intercooler,
ambients,
boost before and after intercooler,
and maybe Egt's and AFR at time of peak ACTs.


It would take more time, but would give a true results,

As on my cossie once i reach a peak ACT on my 1st run, i can (tried many times) then do 4 more back to top speed runs and the ACT stays the same peak figure ( Thats all with my water inj turned OFF).

 

all above edited with the results from the Pf test.

 

 

I had the Rad tec one, got it from Rapid Ford on E-bay and was the cheapest around.

My cossy was running 400 bhp and the intercooler was lovely

My average inlet temp was 20-25 when driving normally. even in summer it really did not go up much

This is my Fiecos prototype intercooler,
designed by me, usin Ah fab's core (same as in the pf test), but now 2 years old, and now getting new one made, better core, and end tanks.

even in 28oC ambients after 4 back to back top speed runs at brunters change temps peaked and held from 7000rpm in 4th till 7500rpm in 6th gear (130 - 169mph 0r 15 seconds) @ 43oC with water inj off (38oC with waterinj on)

 

Gus your inlet is wrong for one!

 

rads what you mean?



cheers for info folks

 

Just seen what you said in the RST room...

RS500 coolers have the out on the right, Could be a fair bit of work thats all!

 

 

weld some cossie one,s together
all the big bhp cars do it so they must be better
but also depends on power output

 

The only problem is with that is the air flow getting to the rad, as cossie inters are alot narrower than a 500 one, so the end tanks hide the rad = over heating problems.

 

Martin Hadland's new car will be fitted with a Proalloy intercooler.... enough said

 

 

as its for me s1 i think i will be using pro alloy as it might need modifying in someway

 

speak to Karl at NMS and check out his quad cosworth intercoolers, they are HUGE!!!!

 

who supplies radtec cooler for best price then?

 

Dan @ rapid ford is good .

 

give that chap wayne a shout at pro alloy, he can make one offs he may have already done a cooler that size for the s1 and have all the drawings ready to fabricate

 

will do pm already sent


pro alloy is only 45 mins up the road aswell so could take shell to them if needs be


thanks chaps

 

radtec were selling them at autosport for Ł250

 

fucker! shame i wasnt there then

i see rapid ford selling on ebay for Ł325 delivered i think. I was hoping for Ł300 or less...

think they'd do a deal on couple of people buying at same time?

 

pro-alloy group buy !

 

well at the right price im interested. Had the stupid thought of buying one now and cant get it out of my head so im gonna have to do it

soon though before i get sensible again

 

Fancy ask Pro if they'll do it? and at what price for what numbers?

if we could get it for around Ł300 or under i'll buy the rad aswell

 

we would be interested to chat about a group buy......
really easy to sort out......
what kind of numbers would we be looking at????

 

chops... I thought you had a pro alloy cooler???
you were one of our first IIRC?

 

we would be happy to take a look at it for you...as long as you are not in a hurry.....the workshop is fully booked into March
The other way to do it would be for you to make a cardboard mock-up and we make it from that..
or
frankenstein motorsport have done this convertion with one of our coolers..maybe worth having a chat with them?

 

yeah group buy sounds good will be needing a 500 cooler pretty soon

 

count me in, i'll take a cooler if the price is right, and if its cheap enough i'll have the rad to match

 

how many do we need and for what prices?

 

nah mate not guilty. You might be thinking of my imposter on here called "lamb chops"


so anyways how many needed for a group buy? i was ready to get my wallet out this week...

chop

 

WOW! pf HAVE RE- RUN THIS TEST IN THE 'COSWORTH COLLECTORS SPECIAL' WHICH HAS JUST BEEN RELEASED

 

Pro -Alloy mate, the guys are friendly and can customise it but you would have to wait

This is the new super wide, (140mm more than standard) and super deep (65mm instead of 50mm) with the patented (so I expect royalties : ) R&B scoop design Pro-alloy intercooler.

I will have some temp figures by end of Feb when car goes to Bruntingthorpe.

 

sorry mike .. been using a scoop for the past year on my pace rad /rs500 setup you are so far behind..
but reading the test results looks like the origional RS500 one is the worst one .. oh well i got mine free so i dont care
