so true when i ran the supra at santa pod last year it was 32d that day, at the start line my act temps were above 65d ! they were in the 30s by the end of my run but i dont know how far i went to get to 30s as i cant data log.

v man

my input on this came from a very big well known cooler maker

what i typed is purley his own advise as he made me a custom 1 off rad and cooler and mounted the two as closely together as poss
and the car the cooler is fitted to has no problems what so ever

and the car in question is a 500 bhp zetec turbo fez

but surely a shit hot cooler and rad will have such good recovery when moving anyway

i can't even be bothered to begin unpicking that load of twoddle

v man

did you read my post above yours

v man

so you had a 35d drop over a quarter

is that with the cooler and rad close together

Mike1

Ian's old car still going well then Dave!

Hope you find the missing ( if they are indeed absent ) horses soon

yes i had a massive drop but i ment 45d not 35d, so 20d drop yes, ive not taken much notice how close together they are but they certainly arent touching, its a massive intercooler though Ł1000 hks one. i think its 130mm thick !

also bear in mind i was hitting about 140 mph by the time i was backing off.

Yes the cars still going. Not so well on rollers though.


Going to make a few changes and improvements around the inlet system (spacing/heat shielding/wraping etc), then take it for a run on a private deserted road and monitor boost and act up the rev range.

My cooler is a 50mm Pace one made in 2007, so maybe not the best in comparision to the current units around, However, should be up to it for the 350hp i'm aiming for.

foreigneRS

yes, that was a load of bollocks as well

Stu @ M Developments

They are wrong.

v man

oh shit yeh i forgot you was there when my self and said cooler maker had the long conversation together

my bad

v man

well the sujested set up works perfect for me with no issues so im happy

Stu @ M Developments

iTrader: (12)

It may "work" but I assure you if the rad and intercooler are bolted together that it works far from "Perfectly". However, as long as your happy, nothing else matters... just beware of giving people bad advise like that as all it achieves is costing people money, or maybe even engines.

RS331

I boost at 30 PSI and hold at 28 - on a T3 stage 3 Hybrid from Turbo Technics, with 34 actuator only f**k knows what a larger turbo from turbotechnics can hold, im maxing my turbo out though when i floor it, spools up instantly and lays it on thick !!!!! right through the gear ratios.

also try going to a different RR and see what their one tells you ?

I use GRS intercooler and PRO ALLOY Radiator, very very little clearance but i have good air flow and coverage.

iTrader: (1)

V man. Was it Pro Alloy who gave you that info?

v man

thats all well and good saying its bad advice but like i said its advice ive been given by a professional in the industry and what works great

i never give out known false or damaging advise thanks

v man

careful with tht last bit mate the pf sheep with never belive it mate

v man

no mate it wasnt
but have you known them to give that info before
think its best not to go down the name who it was road as it will just start a cooler war lol
and i dont want to be the next cossie4i lol

Stu @ M Developments

iTrader: (12)

Back it up with some thermocouple info and we will all happilly believe it mate.

As said earlier, any clearance is fine, its contact that isnt.

PF sheep will never believe what?

v man

sorry for the confusion here stu but in my first post i said to get the cooler and rad as close as poss

never said bolted together

and as i also said if the cooler and rad arent great quality then it aint going to help is it

Stu @ M Developments

iTrader: (12)

Sorry mate, took these two quotes to mean you were advocating them being bolted together.

If thats not the case, then it seems we actually both agree after all. LOL

You are though! Stu does this for a living day in & day out, and sees hundreds of cars a year! I'd listen to the pros personally!

He dosn't come to your work & knock the sailors cocks out of your mouth does he? ( This is a joke btw, Jimmy Carr, been looking for an excuse to use it for ages!)

v man

think we both do mean the same thing just came at it from different angles

if you read all my posts that havent been edited then you can clearly see ive sujested getting the rad and cooler as close as poss

never once said bolt the two together

so id just like to thank the others who tried to shoot me down when they havnt read all the post clearly


the fact is if the gap between the rad and cooler is too big with a 500 style cooler it can and will give water temp problems
would you say thats right info stu

v man

you have joined the new passion ford ''dont read posts correctly'' club

and working in the air con industry, air flow is very important

RWD_cossie_wil

iTrader: (9)

No I have joined the Passionford ambiguous post reader club

v man

lol but you havnt read the post correctly

RS331

Lol mate not fussed if the PF Sheep dont believe it, i never thought it possible myself on a T3 looking at Pressure capabilities of the T3 but my turbo is not just a T3 its 3 stages above it but please trust me on the 30 PSI and 28 steady.

Turbotechnics are the global leaders in turbo balancing, building and machining and for my T3 stage 3 to do the 30 PSI it does is very much a great thing haha. so i would recommend them to anyone looking for top class engineering and balancing and along with it unrivalled reliability.

i dont drive hard 24 - 7 but ii know the turbo i have has 30 PSI maximum capability, i mean holy shit 20 is enough without using all of the pedal !! so i tend to drive like that, regulating my boost through the accelerator but would probably benefit from an electronic boost control system. As 30 PSI , when i use the whole lot is just PURE AND UTTER SAVEGERY on the motorway and doing quick boots down town high streets, got to love the old people taking cover when the wastgate blows off the excess pressure, they must think its a bomb dropping the poor dumb bastards, i mean especially down town streets where the sound bounces of the walls either side and sets of car alarms when you go by lol, ive even somehow managed to to get a women in her 30's hold her hand bag over her head while leaning and squatting against a shop window while i accelerated quickly then blew the wastegate off, i do it deliberately admittedly but its a good laugh.

I have a very large pace radiator and chargecooler rad in my 5.
They are bolted together, i dont have any engine water cooling ossues but i do have act cooling issues (many different reasons why that im currently sorting)
One of the things i am thinking of doing is spacing the chargecooler rad.
Currently the engine rad has locating lugs in the bottom and a couple if support bars fixing the top.
Then there are 2 90brackets welded to the sides where a bolt goes through to a nut welded to the pre rad fixing that.
The end tanks of both rads are currently touching.
Due to this i cant move the pre rad easily but am thinking i will try putting a small cotton reel in to fix the pre rad and give a small gap, then use some foam to seal the joints.
Does this sound like a good idea?

v man

i remember on my r5 turbo on a really hot day with the car parked all day in the sun the temp gauge on the dsh read warm lol

thats with out the car even being run

and with a charge cooler set up you have water to cool not just air

foreigneRS

what do i know, i only worked for a leading global automotive heat exchanger manufacturer preparing and testing their products on vehicles in a climatic wind tunnel for 12 years?

as close together as possible is not best as long as they are well ducted so that no airflow gets lost in between. don't talk nonsense about low pressure, low speed etc, as the pressure drop through each matrix is the same whether they are close together or far apart. either your so called expert was talking shit that you are regurgitating, or you misunderstood them

foreigneRS

you definitely want to thermally isolate the chargecooler rad from the engine coolant rad, otherwise it will pretty much always be coupled to the largest one, the coolant rad (especially with no airflow through them). create air gaps and use plastic mounts wherever possible, but make sure that all airflow (particularly that generated by fans) gets properly ducted through both cores. closed cell foam is good for that.

Sounds logical, i've just bought a roll of foam draught excluder from b&q, that i'm going to use.

v man

i also mention ducting

people have mentioned having a 5 mm gap
do you think a 3 mm gap will be much different

remember we aint talking about sitting in traffic conditions

please explain how you can have 2 surfaces 1 behind each other and the second has the same air flow speed than the first

foreigneRS

i don't understand your question, if indeed it is a question, about air flow speed? do you think the speed of the air is important, or the quantity of air? if you think the speed is important, presumably you think faster is better?

Stu @ M Developments

iTrader: (12)

Erm, you never once said "Close together but not touching".
We all read it properly, and it was patently unclear what you meant to portray, as to most people, "as close together as possible", would indicate pysical contact.

I was very clear in my statement that they should not touch as everyone seems to know what I meant, so I think rather than fire sarcastic smileys around you would be better off giving more attention to your wording.

At what boost James? mine is running similar spec but a 2wd exhaust manifold and the same chip according to Stu.

Mine peaks around 32psi on the secs but havent really noticed what its held to busy keeping an eye on the road.

Pulls well with plenty of torque tho

Took the car on the road yesterday and found that the inlet temps were high 30's raising to 50 oC at the top of the rev range (ambient temps about 27 oC).
What temp is considered too high and does anyone know what temp MSD maps pull back performance for safety?

As has been sugested by Tony 'Turbosystems', i think my Pace cooler is not workig very well and inlets way too high.

Sticky.

iTrader: (4)

Has Robbie got a big cooler you can try?

All ready for Tuesady?

performance is lost with air temps going up purely because of the reduced oxygen content by volume
climbing act's are often a result of the the turbo compressor being out of it's efficiency map
what was your boost curve with rpm
when the weather is hot and ambients of 27C the air temp will rise
hot weather the car will be slow compared with cold days
your power loss has nothing to do with any std weber safety strategy that is in your chip at 50C act
You will know when these are activated as the power will just switch off
My advice is to take your car to a real specialist for examination and proper advice

I'll send him a txt and see, just need a load of fuel.


Tony
When boost comes on in mid 3000's giving 30psi, soon drops to around 26pi, holding about 23psi at the top end.
I have just spaced my cooler OFF the radiator as they were against each other at one end.
