Airflow To Radiator?

[Erko]

Thanks mate, got an intercooler for me?

[RAP1D]

Certainly do... maybe a custom track cooler would suit

Ah those pesky AWD cars pulling in tight on the last corner! They get me everytime lol

1;16s are still good... I can remember doing 120s 8 years ago and thinking it was fast.

If you get it into the 1:10s it'll be a dam fast car and an awesome achievment.

Hmm, Ive got a GTR style tube & fin IC sitting on the self here... might carve up the front bar and fit it, be great for the track as its only 300 high

Maybe the AWD cars with not so good drivers.

My son runs around Wakefield in high 1:07's in his milded modded Evo 8 and with stock suspension. and standard brakes.

The Ford will do much better around Eastern Creek, as the tight Wakefield circuit doesn't suit the Ford.

Absolutely Brian agree re WP / EC.

I do think that 1.10 is realistic for a decently set up XR6T/F6 at WP...power not really the issue, its about chassis, brakes and tyres.

Recently there have been a lot of questions asked about what construction is best for heat exchange and air flow to radiator , tube and fin or bar and plate ? Both have their advantages , but .....

Ask your self this question ....... If the bar and plate intercooler is better for cooling ?? then why are 99.9% of automotive and truck diesel RADIATORS tube and fin?? And why are most diesel INTERCOOLERS tube and fin also ?? These are big $$$ machines and only utilise the best heat exchange cores for reliabilty and performance . And dont say that these are cheaper to produce either , as a properly constructed tube and fin is far more expensive to produce than all bar and plates.

The Plazmaman catalogue caters for both tube and fin and bar and plate . The secret is to know which one is best suited to the application required . Our tube and fin is an all round performance core - being curcuit ,street or drag . It has very good radiator air flow caracteristics.we also have a few variants of this core , including a heavily finned internal version to suit big boost applications . Basically we have horses for courses.

External finning is the secret to air flow to radiator . Once getting over 80mm thickness , this air flow is greatly decreased if the core has the wrong external fin construction . Our 90 and 100mm cores have different fin constructions as compared to our 60 - 76 mm cores .

It is best to research this topic on google yourself and talk to heat exchange experts , this way your answer will be unbiased and true .

Sorry Alex, you are dead wrong.

The reason tube & fin is used in OEM is cost...it is much cheaper to produce a tube & fin core over bar & plate. The intecoolers designed for use in standard cars are just that...for standard cars.

Ive now been to 5 different heat exchanger factories around the world and watched first hand how each is produced. Ive also watched the comprehensive testing done in their labs of each type. (they all test the competitors product, as do I).

This is the reason I use the core type that I do and why and am so confident it is the better choice. Time will tell is all I will say.

Last time I checked this wasn’t the primary school play ground; if you can’t type a post without juvenile insults then don’t bother.

Unfortunately a lot of good information/debate gets deleted because of this, so stop wasting your time and ours

Majority , if not all trucks these days still use tube and fin . Trucks are worth nearly 1/2 a million $ + , carry 50 + tonnes daily and boost to 50 psi + . I am sure major companies dont take a few $$ price into consideration when day in day out reliability , weight and performance is of main concern with these heavy vehicles .

I am sure that a vaccum braised furnace , laser welded tube , internal fin turbulator tube and fin cooler will be nearly double the cost of a bar and plate .

There is no way in the world that you will let into test facilities of any major heat exchanger company . Most of these companies dont even want to know you unless you are purchasing thousands of cores a year . Most test facilities of heat exchangers companies span accross full industrial blocks , with some 100 thermal engineers in the R&D departments . There are only a few companies in the world that produce the plates , bars and tubes - Corus being the major player . These are sold directly to nearly all heat exchange companies in the world . So if they all use the same raw material , why do they need to test against one anothers products . Engineering departments are primarily for the engineering of new types of products .

More incorrect information from you

In 2002 I visited THE best heat exchanger manufacturer in the world ..API Airtech in Arcade New York USA. We did a tour of the factory and had an in depth look at their test facility. The week before I went out for a meal with the US sales manager in Vegas (during SEMA) and got a very in depth insight into the heat exchanger industry.

In 2003 I visited China twice and went to 3 different heat exchanger manufacturing companies.

All of these factories make their own fins, bars, plates - everything.

Below are a few of pics that I took from one of the Chinese factories I visted. The US factory wouldnt allow any pics to be taken.

Love it when these two talk about coolers always good entertainment
