Is it correct you get around 50 bhp from the exhaust manifold straight off on a 300 bhp engine then around 40 from the inlet? as this sounds a bloody lot to me???

 

In a word...... No! lol
Bit more to it than bolt on and receive the horses...
If they are not your restriction in the first place then they will make little or no difference for example, all depends on the full spec of the car.

 

I did wonder as it sounds alot especially for the exhaust manifold.

 

ian says that on a 300bhp engine his inlet manifold will give you around 30 / 40 bhp with additional mapping to allow for the extra air, as for the over gearbox exhaust manifolds they dont really aid in bhp (but you will see a gain) they aid in torque and allowing extra cooling of the radiator , intercooler and inlet systems as it moves all the heat away from the engine that what they where designed for. these have been flow tested and compared to many other well known inlets and is far superior (even though people will argue which is what opinions are all about) in every case. to be fair there is only one other inlet that has been tested and has been provern to flow over 500bhp so i think ians knowledge speaksfor itself. i know ian well and these are very good quality ,infact the best fabricated ive seen.







cheers paul

 

i thought there were a few manifolds that have been tested to over 500 horses

 

can you enlighten us mate?

 

care to enlighten us please as always looking to improve my limited knowledge

 

when the throttle plate opens it WILL angle the air flow into cylinder nom 4.

 

as said before your talking out of your arse , instead of trying to be clever than anybody else tell us your theory , design something better in the next few months and i will stick your inlet on my engine as i still have everything mapped up and ready to go before i change to the 8 injector setup , instead of calming to be able to make one better (like last time) put your money where your mouth is!!!!!!
remember i paid for a 460bhp engine and got 522bhp not many people get that and that was with the above inlets bad design flaw
i think i smell something

cheers paul

 

pmsl tell them how it is paul

 

so is there only 2 options open to us if in pursuit of 500bhp or are we down to 1 now

 

well mate , everyone knows iam mates with ian but i would not stick up for his products if they didnt work its as simple as that , but they do and they are provern. plus if there was any issue with the inlet iam sure harvey and ahmed would of seen some sort of issue between cylinders and maybe cause det issues but ahmed had the det cans on and said its a solid engine so i think i will choose them over somebody who says he knows better

cheers paul

 

we have a rather special one WIP

 

your alive how'd it go with the sale not seen you much up our way lately

 

you mean we have a special mapper!

 

jenvey has been tested but only on a evo engine and produced over 70bhp over the standard inlet which is a vast improvement , but i think anyone could design there own inlet but the key is getting equal amounts of air across all cylinders and this research and development can only be done with flow benches etc and people havent got the resources or money to do this knid of research so they buy the next best thing which is the area six inlet(just my opinion)

cheers paul

 

i look forward to seeing it mate as i think everyone can learn from new ideas , the world doesnt stop at ians inlets dont get me wrong but they are hard to beat in terms of looks ,how well made they are , reliability and being a provern product

 

the above reason is why i like the monotune design which is similar is design to the one in the thread in gd about the audi that was taken to Fuck Me Sideways

 

thought so rabbit, rabbit , look at the end of the day the thread was about an area six inlet was it not ? so iam of course going to talk about an area six inlet , but because" i love ian whats his face " so much i think i might now nip out and do a 120 mile round trip to go lick his arse, look you talk a good inlet and thats it and to say that this design will cause lean running and might melt a engine is utter shit , maybe my friend paul johnson ,dan arrowsmith , sunny , adam moran ,sid , ian himself all running the area six inlet and running the engine at full power down brunters and drag strips running full 30 psi of boost doing 170mph plus , as iam sure there would of been many engine failures at that boost level if your theory was correct , and you can question who you like boy because its not my design so i dont give a flying fuck to be totally honest. i surpose your now going to say that the new jenvey inlet is a bad design and that they know fuck all about induction systems and that you could also design better than them,
well its a shame you cant build me one of you magic inlets , maybe they are like my car a 'myth' , and your the one who has been insulting coming on a forum saying that you with NO EVIDENCE WHAT SO EVER can build a better inlet than someone who has provern it time and time again .

i think jackonory , jackonory springs to mind

anyway iam going now as i must get some sleep and dream about what your inlet could of looked like , hang on you didnt design that inlet that was in the AUDI field motorsport thread did you??????

LOVE PAUL

 

I was amazed at the quality of them when i saw one on a car recently and if they give around a 40hp gain then there worth every penny, have looked in inlets alot and whats available and these seem to be the best on the market Thanks for your advice Paul.

 

Don't get me wrong here, Ian's inlets do produce the figures, noone can argue with that.

However Garage19's points he is making are valid. Also, I believe he designs his inlets on Solidworks and runs CFD analysis of them. So it's hardly a case of "no evidence".

Both may well make the power, but just because it makes the power desired does not always mean it is a good design if you look at the airflow.

 

Garage19 regularly builds inlets for the likes of Harvey Gibbs so his work is very well respected!

 

if your point is valid about the throttle body (which scientifically it is) then could the problem not be resolved by rotating the TB 180* so at part throttle, the air is directed down into the plenum rather than into the number 4 cylinder?

 

I'd go with what has been tried, tested and proven to work.

 

well then problem sorted

 

Garage 19 - do you have a flow bench? I may have a couple of inlets which I would like to see what sort of flow rates appears on each cylinder. Is this something you could do?

 

No problem Doug, will drop you a pm later, dont worry this is not advertising as I have no intention of paying.lol

nice idea , but i no longer own the area six inlet as i sold it over a year ago but maybe luca might be able to help with dimensions. even though you clearly have equipment that can test all this , theres nothing like on car testing and something everyone should say about his engines is that most of them are all at the top of the table in performance ford shootout tables , and most of them was over 5 years ago , so i think that also says something about how much research and knowledge ian has done . its like anything in real life conditions the zetec head on the flow bench can keep up with the cosworth but we all know that the cosworth head will produce far more power than the zetec ever will fact!!. look mate at the end of the day until you or someone else can design and make a product for a reasonable amount of money then i will say these are the best , its like anything , someone will come up with a brilliant design and make a great product from it , then someone will come along and copy the concept and modify it and in time it maybe improved , but youve first got to do it and the fact you havent is a shame.
