Airtec £395
Spec r £800-1000

Inlets are very good also either make.

I'm bored of it too and it was the black 3dr with the stickers all over it don't know his name! By the way what's with all the xx? Are you bent? And I've nothing against the air tec stuff if that's what your after then fair enough but looking at the pics I'm not

ajamesc

na I think he is just bellend some people just are lol

He isnt a bellend mate i do know him very well, he does come on here and seem quite out of character from time to time.

I think that 600 pounds is a lot of difference. If you are building a project then you will have to buy SpecR if you are not Airtec will do the job fine.

Reading these posts I see a kind of competition between some of the members.
Do not forget that we all have the same cars so we all belong on the same team!!!

ajamesc

I guess we all seem different on here to what we would be face to face

The Garrett cored intercooler I pictured is a Presicion 650. Basically Presicion stick there own end cans on a Garrett core (very much like they do with the turbos!). In the states they are $400, so by the time you get it over here it works out at roughly £350 including import tax and shipping. I've personally seen them work comfotably on 600hp cars. It's not a big intercooler by any means, but the core is very efficient.
Cheaper than the Airtec and superior in every way!

no way it can't be superior miller aka doug airtecs no1 fan lol says the airtec one has been tested he has seen it! The fact the garret core is much better dosent mean anything

A T38 at 36psi is over 400bhp, looking at the injector duty I would estimate a good 450bhp and gets used hard lap after lap,

The airtec top feed cooler although pretty cheap for what it is, works far far superior to any other cooler I've personally seen on a yb.

We did a 4th gear run to the limiter and the charge temps were 1 or 2 degrees above ambient, which is pretty damn good by any standard.

Nobody says the spec r one won't be better, but for 99% of yb owners even the airtec is an overkill, if you class yourself in the other 1% then that's up to you and your bank account.

For me they are a fantastic product for a fantastic price and I am more than happy to recommend them to my customers because I know they work.

ajamesc

that's what I'm looking for an informed opinion not some mug trying to be funny thanks!

James @ M Developments.

It's also worth noting that we chose to run Ronnies car out of the turbochargers comfort zone and up at high boost levels, when you are really pushing things to get as much as you can from a smaller turbo, the charge temps will be pretty high and increase dramatically.

The charge temps on Ronnies car are probably considerably higher than as an example, a gt35 at 2 bar because the bigger turbo is walking in the park down there

so it is all not overly as relative to BHP, as in the example ive just posted the gt35 will make far more bhp, but also have far less charge temp being produced.

The only way to measure an intercoolers efficiency is to monitor the inlet and outlet temps, and the flow and pressure.

Statements like "it needs to do 600bhp for 20secs before i'll think its any good" are a bit off the mark. If your turbocharger is large enough to make 600bhp at 1 bar that would be pretty easy.

So after reading all this one thing is certain, Airtec are the China of engine modification?

James @ M Developments.

iTrader: (2)

Alan is not Chinese as far as I'm aware, although he is pretty small.
Maybe that explains it

Beetlejuice

I think he was referring to China's reputation for knocking off other people's hard work. Obviously China's reputation with regards to the quality of these knock offs is fairly apt in this situation too!

youd like Doug hes a real nice lad Andy he will help anyone if he can

what ive found with the hart inlet is all the threads are shit most need re cutting or helicoiled but never had to do this with the airtec copy or not

ajamesc

I helicoiled all of mine after stripping 2 of them

Jay,

iTrader: (4)

tbh Matt 5 years ago id of said yes ! but in the last 4 months ive fitted intercooler/inlets ect to various cars and they have all been a great fit and work really well

foreigneRS

that last statement could also be off the mark.

a small turbo not flowing much but at very high temperatures is far easier to cool as there is a bigger delta between the medium being cooled and the medium doing the cooling than a big turbo flowing a lot at not very high temperatures.

Just to add the pictures of the cores on the last page cant be true of the airtec as you can't get a picture like that of the core. But It's always going to be obvious that the spec r item may be more efficient but for average Joes road car its a little overkill - I was told the 100mm was £1k and you wait until the end of time for it to be made.
As for the inlet anyone is more than welcome to buy an airtec inlet and then straight swap for my hart inlet

James @ M Developments.

iTrader: (2)

Hence why I stated the way to test a coolers efficiency is to measure inlet and outlets temps, along with pressure and flow.

thanks Steve, Jay love you guys

O and have some of these seeing as im batty lol

Maybe i was reading too much into your replys but to me it read that you had an axe to grind? If thats not the case then im sorry for going on. that pic posted above, to me looks nothing like a airtec unit altho i havent seen any of the old stuff so couldnt say for sure but the stuff alan has now is very good indeed.

Beetlejuice

What I pictured was their intercooler for the mk1 Focus RS. I'll see if I can dig out some more if you like?

COCHYN

This thread's a right joke All derived from little batty boys that don't like copies

Jay,

iTrader: (4)

well there are so many people copy products and its how well there done and as far as as that inlets concerned alan refined it tbh BUT the intercooler debate spec-r have proven to make a unbeatable one for a race car under massive stress but most road cars wont need it

MADMAXPTT

How about to return this post to Airtec inlet manifold?

adamski frst

Well back on topic I saw the airtec inlets at ford fair and I closely inspected them after reading this post and I can confirm 100% there is NO internal difference in finish it design between the 2 so all the people thinking there is your very confused as I have a hart fitted and had plenty of pics of it and the airtec was exactly the same..... so that puts that to bed the only difference is the price which if they can sell them for 350 go for it. Business is business.

MADMAXPTT

Has anybody test the Airtec inlet manifold(hart type)?
Any power curve?

ajamesc

There was never any views that the inlet manifold was not the same there taken from the same cast! The debate was over the intercooler as the spac r one which it mega good at keeping the charge temp in check uses the garret core but the copy dose not yet claims to be the best intercooler on the market going by its eBay add but at the end of the day it's each to there own

P.s I no that's not what the topic was about but it got onto that lol

iTrader: (15)

I didn't do a back to back test when i changed from a ST Escos inlet to a Hart inlet but i gained 16bhp with about 2psi less boost.

Both runs done on different DD rollers

Steve

MADMAXPTT

how this inlet behaves across the rev range?

cossie daz

Its a no brainer for me , wait months from spec-r or get airtec in a few days
It's nearly half the price from airtec so that's my way of thinking . Ive only bought airtec chrome but will be buying cooler and inlet

To be honest Ive been let down by spec-r afew times now due to time and wrong parts so I won't use them for that reason
I gave them another go though r&b as didnt want to go direct as let down before and mike did chase them but let down by time again .

H15 FSC

i would like to see these maths rod, what research did you do on these coolers,
just what the acts were??

is there good flow distribution across the cooler?
whats the space velocity?
what is the the residence time of the air in the cooler,
was there a differential pressure across the cooler???
what is the mass volume of the cooler.

all make a difference in the way a cooler will work. its not all about acts!!!

ajamesc

when your goal is to keep your atc,s down it is all about atc,s lol

H15 FSC

lol maybe, but you could have great acts but more lag, crap throttle response, more load on the turbo as the volume is greater.
I've never seen a cosworth intercooler with good flow distribution which will help cooling lots,but due to the lack of space its hard.
there a good happy medium that don't involve just low acts.

MADMAXPTT

I thought that topic was for Autospeliasts inlet manifold!

adamski frst

Exactly my point of my post why not go make a new topic on the coolers?

ajamesc

It was about the manifold but turned into both lol why not live with it
