Anyone know who can supply an inlet manifold for a Zetec Turbo, either new or second hand?

I've seen that Sitec Racing does them starting from £500 so am going to give him a bell tomorrow but is there anywhere else I could try?

 

EBAY

 

Cheers mate, I'll keep an eye on that. Could be just what I'm looking for.

 

R6Franky is breaking a Zetec turbo Escort at the moment, which has a modified Rover inlet on it, he's in Whitburn so local to you.

 

£500! Bloody hell. Thats a bit steep!

 

Area Six
Jenvey
Converted Rover Ones

There are a few examples. If I had the money id be going Jenvey

 

why not just use the rs1800 one?? good for decent power

 

the one on ebay looks good.

 

I wonder why

 

Try Area-Six http://www.area-six.co.uk/


Brian

 

I thought Area Six had shut down

The Jenvey one looks the bollocks but might be a bit too much to shell out at the moment.

I've PM'd R6Franky about his.

Also gonna keep an eye on the one on ebay.

Cheers for the info.

 

Ian re-opened a few months ago

Nice contrast against the red rocker

 

the jenvey inlet is a very nice bit of kit but way over the top and very expensive for your average zetec turbo.

 

hi mate i must inform you that the area six motorsport is a zero loss intake and has spent many hours of development work on the bench dyno to make this the best zetec inlet available for under the £1000 mark . as stated above there is no loss of air across all cylinders and can easily flow 500bhp+. i ran one on my old engine but now we are trying for ultimate bhp i have changed to the jenvey item with the new 70mm diffuser designed for the evo engine but at nearly £2500 with injectors , throttle body then all the parts it certainly aint cheap.



i must also add the ian howell said he has seen a 30 to 40 bhp increase on a 300bhp engine just with the inlet and a map tweek so its good value for money at £750 in my opinion



hope this helps mate

cheers paul

 

design your own & get somebody to make it for you

 

If the Area 6 one is Zero Loss, why are you changing?

Rick

 

Zetecboostboy,

Are you an Areasix sales man? Sure sounds like it.

I'm with Rick. If it is zero loss why have you just spent a small fortune on a different one??

I do a fair bit of fabrication and can quite honestly say that £750 for that manifold is just daft.

 

when i flow tested mine on my flow bench there is a small loss that is equal on all four ports but as its for a turbo engine its irrelevant as it its forced induction and not a n/a motor . and i find it hard to believe there to be a zero loss on any inlet.

and as for £750 sod that

 

rick . larger flow volume , fully rebuildable , different configuration of diffuser , 48mm runners instead of 45mm . why is it just because i try and offer advice you always try and argue the point with me and try and prove me wrong , the lad was asking for advice and opinions and i gave mine , take it or leave it!

garage 19 . no i aint no area six sales man , its simply a case that ian has done more research and development work on zetec turbos than anyone else has and someone was asking whats a good inlet so i gave him my opinion.

crazycage . thats your opinion ,but i know who i would listen to and iam sure "your inlet" (rover) was first used by ian on sunnys engine over 8 years ago so if that was that good why did ian design another inlet? easy for better flow for greater bhp.

cheers paul

 

you are right ian did use the rover inlet on sunnys engine and paul j's but both had standard rover plenums on them.
i agree with you that both the jenvey and ian's are good but just not worth the money imo.

 

Larger flow volume??

You have stated that the Areasix manifold is ZERO LOSS. (which is bollocks)

I guess what you are trying to say is that it flows more than your inlet port so there for there is no restriction.

If so why spend another £2.5k on something different?

You say:

-Re-buildable? So what. Why would you want to get inside your inlet manifold?

-Different diffuser. Why would you need that? You say the Area six one has perfect distribution across all cylinders.

-Bigger runners? Why would you need that if if the Areasix one is ZERO LOSS?

At the end of the day i could fabricate and sell the area six one you have shown for £250 and still make a reasonable profit. To me that says that someone is getting £500 for simply being the middle man.

 

By the way, i can see a huge problem with this manifold. I'll let you see if you can spot the flaw in the design!

 

Angle of TB?

 

Thats what I thought.

 

ok mate what ever you think thats your opinion , zero loss is across all cylinders not the volume it can hold in the plenum (cubic inches ).the jenvey is far bigger in volume (cubic inches) size than ians inlet and we all know that a good inlet flows 1.5/2 times the capacity of the engine.

- rebuildable and easy to change componets of the inlet which drasticaly alter the performance of a turbo charged engine. air horns can add masses of throttle response to the engine so you can choose from many different air horn designs from the jenvey range to fine tweek the engine but of cause you would know this better than me being a mechanic.

-different diffuser purely for my application as iam going 4x4 in a mk6 fiesta so it will allow me to mount the diffuser top or bottom depending on whats going where and how much room ive got (ideal for me) as i dont want to be cutting up a new inlet and having it rewelded.

-bigger runners , ive stepped upto 48mm from 45mm as we have added a extra 2 degree tapper as they have been ported from top to bottom of the inlet runner and the zetec engine flows best at 15 degrees if i remember right and the jenvey plate is 12.5 degrees ,this again will flow more air but it effects velocity .runner lenght and shape (which i can change as well with no welding and austen stated that 12 inch long runners would be best for max torque which i will never fit in) determine velocity and relate to what is called a ramming effect on a engine. air is thought as weighless but its not the case as talking to many cylinder head peeps that the fast momentum will turn into kinetic energy so if the runners are tuned correctly that energy can be used to force air past the inlet valve and raise the volumetric efficency which inturn will raise bhp and torque. longer runners will have an effect at increasing bhp and torque at lower revs while shorter runners will increase bhp and torque at higher revs so you need to find the balance between the two.

- £250 ok mate you might be able to fabricate something like that but as for profit not much i think. first of all you pay for quality and jenvey stuff costs so ian aint ripping anyone off as nobody HAS TO BUY THEM!. the inlet plate is £220 , x4 air horns £100 , machining of the inlet plate for injectors £40 , throttle body plate machining £20 , fuel rail £35 , fuel rail brackets £20 , the alloy plate cut to size (i would say £60) welding (dont know but could find out as jim is welding my car ) vaccum fittings £10 so i know ian doesnt make that much on them so for your slating of him being a middleman is a bit below the belt.

as for the design flaw , you have only got so much room in a mk3 fiesta bay without changing everything so that was my choice but it still made 500+bhp on the dyno so i think most people will be ok.

cheers paul

 

1) You are confusing plenum volume and flow rates.

2) I'm not a mechanic. Not sure where you got that impression.

3) I thought Area Six had done all the development so you shouldn't have to open it up and change air horns?

4) You have a fair point on being able to change the manifold entrance around.

5) Are you saying that the runner angle of aproach or the runner taper is optimum at 15 degrees? No need for the lecture on harmonics. The assumptions about runner length are not always correct. It depends which harmonic the runner lengths fall into.

6) You are paying through the nose for Jenvey parts that are not needed. A skilled fabricator could form those parts from sheet for a fraction of the cost. I stand by my figures. If i had to make a batch of five similar inlets i would be happy to sell them for £250

7) No one has identified the design flaw yet!

 

i aint confusing anything as i have researched this well before buying the inlet as i aint the sort of person who throws cash around as i havent got that much ,
ok soz if your not a mechanic
no areasix have only used the air horns best suited to there inlet. we all know that different shapes , sharp conrners etc restrict flow no matter how small so iam hoping and have great faith that this will be an improvement on my engine but only time will tell.
look mate i aint lecturing anyone as i really dont give a fuck its your opinion vs mine and i can see your point but this is the best inlet for the zetec in my opinion and if your willing to build me a 8 injector inlet made to your spec i will gladly take it with me when my engine gets dynoed again and do fare back to back testing and use my engine as the guinea pig. i cant say farer than that ! you up for it? and i will also bring a area six inlet along to compare.
yes iam paying a price and so is ian but thats that , cast alloy will be far superior in strenght compared to rolled and welded alloy and is lighter too . iam happy so who cares hey. ive researched and got good info from ams inlets which are the best inlet for evos and they have built the same inlets with different plenums , tappers , air horns etc etc and have done extensive back to back testing , so unless you know something better than them , then i am happy with the info ive read and collected and my good friend is also the best zetec turbo tuner in the uk and what he dont know aint worth knowing

so come on then tell us what the problem is as i give up ? (even though it worked on my engine and so many others)

thanks paul

 

Honestly no beleif a hand made inlet will be equal across every cylinder every time what chances are ther in batch made by same person they be consistant and identical each time?

 

Tempted to get my mates together on this one, Paul Bamo will want one Id expect, I would and so would another mate especially as another close mate recently bought a Area Six one

Id like to know the design flaw too now!

 

Ok i'll explain.

The throttle body that the manifold is designed to be used with looks like one of those 70mm items from the states/ebay.

Now we all know that a cossie (similar capacity engine) will easily make 450+ bhp on a 55mm throttle body and that for the engine to make that much power there is easily enough cylinder filling to det and destroy the engine if the AFR is wrong.


To achieve the the same throttle plate area as a 55mm body with a 70mm body you only need to open it 61 percent (roughly 55 degrees rather than 90deg at full)

So what i'm saying is that you could be driving along at 61 percent throttle making a lot of horsepower. Now look at the angle the throttle plate would be at!!

All the air will be diverted into the the first two cylinders. There will be a huge disparity of air flow between cylinders with the closest cylinders running far leaner than the rear two. You would not see this on your AFR readings. Only an average of all the readings. The first two cylinders could be happily detting away and the first you would know of it is when the engine fails.

The manifold might have been tested on a flow bench but i can gaurentee they didnt bother mounting the throttle during the tests or they would have never mounted it as they did!

 

Arguing over nothing here...!

Do you all run around Asda saying you could bottle some water for less than a pound?

Area six inlet is an off the shelf product as is the Jenvey you pay the price and you get the product
an inlet that has had some R+D with proven results.

The Area Six inlet around the 350-500bhp mark has proven dyno graphs to highlight its results.

Slight mods and it will do close to 600hp as proven recently.

Until the likes of any of the above people make an inlet that is readily available and bolts straight onto a car, at the prices mentioned hush your gums!

Where are these £250 inlets then if you can make them so cheap why has it taken you all soooo long??

Perhaps the zero profit you would make has put you off?

 

Luca,

Have you ever actually fabricated anything out of aluminium YOURSELF?

No? Hugely qualified to talk about the costs involved then.

Like i say, if i wasn't half way through a house build at the mo i would be happy to design and produce a batch of 5 for £250 each.

Ians prices are high as he has to pay someone else to construct the manifolds. Welding, turning, machining all done by someone else. he has to cover all their profit too!

 

I have not made an inlet if that is what you are getting at.

I understand pricing though fear not! I also understand the development of a product.

I just dont understand what your issue is with these inlets....

All im saying is dont shoot before you personally have actually designed and fabricated an inlet that is capabale of supplying air to a 400,500,600 hp engine. In which will cost £250 to good ole Joe public.



This company make some superb components for inlets when you get a chance.

http://www.rossmachineracing.com/products.html

I am not picking holes in your ideas here they sound great

I just dont see why your slating something that you cant back up with an alternative YET!

 

luca, its just another classic case on here of someone thinking they can do it better for cheaper. Quality and R&D come at a price. Its just the same as people saying i can give you 600bhp for the cost of a 500bhp engine. Or people that say they can beat rods topspeed record at a fraction of the price. At the the end of the day TALK IS CHEAP. They have to then prove it

 

Agreed but to be fair I've seen Doug's work and it is very good.

 

at last two people who have got a bit of common sense , your right luca it doesnt matter how much people talk the proof is in the pudding and until now NO ONE HAS DONE BETTER!. garage 19 how are you going to test and develop you £250 inlet or are you certain that you can design it right first time with no flow bench or high powered engine etc etc to test this on. you could design something that looks like ians inlet but i bet it wouldnt perform better . like ive said my engine wont be going on the dyno for a while so the challange is there if your up for it? and by the way i dont know if you know ahmed bayjoo but hes probably the best mapper in the uk and you never heard of det cans , trust me on this ahmed said my engine was sweet and had no problems and iam sure if it would have both harvey and ahmed would have stopped the dyno straight away , and i would trust two of the best tuners in the uk over you any day of the week.
there is no design flaw as IT WORKS and there was no problems. you can always improve in every area of a car but it cost and sometimes the gains simply aint worth the money or hassle. £750 for a 30/40 bhp gain on a 300bhp engine is worth every penny in my opinion. also like luca said get on with it instead of mounthing other peoples work off if you think you can do better .
this inlet has also been used on
ians focus STILL THE FASTEST FWD FOCUS TO DATE 176mph
adam morans focus SECOND FASTEST FWD FOCUS 171mph
paul johnson fiesta STILL THE FASTEST FWD FIESTA IN THE UK 179 mph
dan arrowsmith 534 bhp engine
my 522 bhp engine
luca engine and last years fwd central day winner
i think that says it all really and your talking out of your arse!

 

there is no way ians inlet will make 40hp more than mine on any dyno mate , and as for luca's car with all its big money and area six manifolds ect was how much faster down the 1/4 than me ?? ow shit you werent there lol ...

this is not a dig at luca in any way and i really do love his car but we dont all have his kind of spending power .

you say the proof is in the pudding and i agree ,i have built my car at home in my garage and me and a friend map it there is no tunner we have no rolling road ect but it will give any fwd a run for there money at central day thats for sure.

 

ok mate but ian says it will and hes the man that designed it and knows whats the limits of the rs1800 , fiesta turbo ,rover inlets are as they have all been on the flow bench and dyno , yes i can also understand that not everyone can afford the best bits thats why my car aint finished as iam skint lol .
and a big respect for you home tuned car and i really hope it does well and i cant understand every time iam on a thread you always have a little pop. my mk3.5 fiesta would of been a very similar spec to you engine but without the rover inlet as i kept the rs1800 so that might of gave you a race but now iam trying to build something in another league and that takes money and development work to push my silvertop to new highs and build a seroius car , it may go bang if it does i will save hard and use the blacktop engine and try again.
no i wasnt there and is that meant to mean something but i know who the winner was LUCA and it dont matter how much quicker he was he came first simple as that.
i dont know why you think ive got a problem with you as i think its great that youve done all your work and your getting good results.


cheers paul
