The less boost you run the longer it will take to come on boost so your statement is wrong!!!
In the real world you should spec the smallest turbo for the job..ie you want 400 hp and 400 lb ft you could ring the death out of a t34 or make it nicely with a ut t38 or even better my choice would be a gt3071 at 2 bar...
A gt35 at say 20 psi will be lazy and shit and any well set up car with the above turbo will rinse your arse!!!
Mark will tell you the same story and you will end up with the gt30...

Why do you want external gate if you don't need it?

because theyre better boost control and i love jb feltches saph!!

since this post ive grew a penis and decided a t34.63 will do the job, 380-400bhp with a reyland external adaptor, i dont really like boost spikes, my old c20let used to do it till i bypassed the amal and ran 18 psi straight from actuator to comp housing, went alot better imo

So you're spending a load of cash on something you don't need, because:

-You like someones car
-It may give you better boost control, which doesn't need to be improved on anyway?

Im just obsessed with screamer pipes, but in the long run its just easier to keep actuator, all that money for external on a t34 is pointless

The results of the cooler have spoken for themselves, and if you think you won't need WI, or a better cooler, with 550+hp on an Airtec cooler, then I feel sorry for you

Have they really, it made the same power but it is Guestimated that in the height of the summer it would perform better that's all.

As for me using my 70mm Airtec cooler it's like you lot using a standard head over ported, So you see where the Airtec looses in ACT's in the summer you lose power in the head all the time

My engine should give 500hp on std head and spec-r cooler, and be 500hp all the time, due to acts, if I had headwork I'd only see around another 20hp. The head was already bolted to the block when I took the build over, so left it

So I'd lose 20hp from no headwork on my engine, but lose probably around the same or more in the summer, with a normal cooler

Would be interesting to see how the Airtec performs back to back with Spec-R with around 550hp

We'll see next summer won't we

If you actually quoted my whole post

I believe in the summer, ACTS on 500hp+ with an Airtec, would be need to be improved to give consistent power

Mate im never led down the garden path on anything!!!once theres a proven product better than any other product on the market i will use it ful stop..
The spec r is that product and is far superior than the airtech and will show myself how much more superior than the pro alloy..

General rant Danny, not directly aimed mate

I know the cooler will work efficiently but what a clan of you are forgetting on here is, this modifying game is a hobby to most who have different budgets raging from fuck all to the other side of £50k+.

Now in that range many people would be happy to have a setup that consisted of products that are to many proven to work to a respectable level, granted not as well as others but on the budget you have it will have to currently do so to have a group of people that bum a very expensive new product slag everything else is a bit annoying.

If i had that much available cash i would have Harvey build and spec me a 700+ motor but i don't so what i have will have to do - you see where i'm coming from.

Like you know theirs 2 ways to a power figure - the hard way reduced prices & old products or expensive state of the art goodies.

I know everyone has the right to speak their mind so obviously you can big a product up but when you get mocked and statements slagged it's a complete piss take.

It's like this, imagine a gang of Bugatti owners dared venture onto this site and picked up and boring Rods thread and slagged it to fuck for not being able to hit 220mph he would feel a little pissed off as the two vehicles in question are at different ends of the spectrum in price.

Rant over.

But what i will add is i will try my Airtec on my spec with a GT3076r set up and see what the results are as you have tested this cooler on a turbo that say hasn't the best record.

its an intercooler, fuck sake it does the same job, both 70mm, ones alot cheaper than the other but the downside is charge temps are 2-3 degrees warmer? LOL

Chris i see your point totally mate but just because you cant warrant spending the extra dosh it doesnt mean you should be blinkered to the fact theres better out there thats all im saying..
Your car mapped with you airtech fitted and it will be fine mate but wont be as powerfull as if it was mapped on the spec r and that is a simple fact that even if you cant afford is true..
Of course if you were rich you would have harvey build you an engine and none of this would even be spoke about but i realise that not everyone can afford £20k+ engines!!lol

Exactly, but the YB has been going nearly as long as i've been born and they have been producing big power on what some class as poor products now so it's like i said there's 2 ways around it the old way or the new way but which ever you can still get there but it might take a bit longer

Just thought Id bring this back up to the top as it is a very interesting thread and might be a good read, apart from the Phil being difficult bits, to some of the users on here who have not seen it before. Was also good for me to read again as a bit of a refresher as its been so long since I was looking into similar things.

The facts are a RS500 Intercooler showed +20 over ambient, on a hot day it would activate the WI. The Spec R showed +7 under the same conditions.
On a cold day ive seen negative temperatures under throttle with the Spec R.
Intercoolers are all about the efficiency of the core & how much airflow it gets. The Spec r is smaller than the Airtec although its much thicker its designed to get maximum airflow from the opening at the front of a RS Cosworth. Its expensive because the core is far more efficient. I researched & bought the first cores for Pete at Spec R from the States it was a compromise between Cost/Efficiency. £700 was the cost point for the Cooler in this market. Far more efficient cores can be sourced but the market wont stand a £2000+ intercooler to get the max from the best cores.
I hope these facts prove that there are no guesstimates when im involved just proven facts.
Childish ranting because you cant afford the best is very childish some can afford Fords some Ferrari's.

I`ve mapped quite a few cars on the Airtec top feed cooler though, and even at over 36psi on GT30s the Inlet temps were only a max of 5 degrees over ambient on the dyno, most of the time the were only 1-2 degrees up on ambient and thats sat on a dyno run after run after run while mapping.
Thats far from bad so i dont see what all the fuss is about. The cheaper one works really well and i wouldn't hesitate to fit one to any car.

on a t4 car running 32psi we were seeing progressively rising charge temps untill they were upwards of 43/44 degrees when running full chat from 2nd to fifth and climbing. this was on a top feed airtec.
i have a pro alloy made cooler on mine using the same core as spec r and i have none of these issues. it is a very good core.
the pro alloy rs500 cooler ime seems to fair better than the top fed airtec.
it could have been an early model if they have changed since then but my findings were that theyre inadequate above 500 bhp for sure.

ps it was a warm day, high teens iirc nothing like were having atm.

I was still trying to decide what intercooler for my engine, but living in Spain I need the best one I can afford, so looks like the airtec now I defiantly out and a spec r will be bought.

Although its away from the original topic I do find it interesting that some see good results from the top feed airtec and others not so good. Is there a known reason for this? Does it vary so much because of the available air flow through bumpers on a 3dr, to Sapph, to Escos? Is there a difference in how one tuner maps to another, on an identical engine for example, that could cause a difference?

Nothing to do with money i'm more than happy to spend what ever if i see fit, i agree the Spec R item is very good but i'm just looking for something that's good enough not the best, i got my cooler when they were introduced and cost me next to nothing and i got it within 2 weeks, it would be 2015 before Pete could supply me with the same he can't even knock out engine bay tanks in 6 months

The difference between our cars is mines a hobby, something to piss about with when i have time and yours a professional vehicle challenging for a title so like comparing a 205 GTI to a T16.

My topfeed cooler showed 1.2 degree increase over ambient after multiple runs

Lol your 100% right Chris ! The spec r stuff is ok Had Pete make the stuff for Julian Godfrey's fiesta Rally Cross car intercooler in the front and the rad in the back had a massive 20 degree drop compared to the forge stuff he was using ! Then we tried the spec r rad/cooler in a 500 race car and found unless the car was run in clean air which only happens if your in front we started seeing water temps of 115 degrees and rapidly rising air temps up to 48 degrees , So put the standard 26 year old 500 cooler/rad back in it was spot on as the cooler was just too thick and needs a good bit a of ducting work and bumper modding to get more airflow through it ! So in a 500 bhp road fun car I agree with James

I take it this was the Brooklin car and was it logged as the time I checked that car on the dyno and found the owner was looking at the 20year old VDO gauge was reading wrong.

Cool as when I checked it they had not thought about checking logging before saying it had a problem,
As I was only checking it for Pete I did not follow anything after that.
