what the max power you can push through them with a 1.6 rst ?

and is there any difference to a rst efi inlet and a 1.4 cvh inlet other than throttle body ?

cheers jim

is there anybody out there ! lol

crazycage

are they not the same as a fiesta turbo inlet ?? if so ive seen them do over 300hp on zetec turbo's and ports are not the right shape for them !!

J1mbo

questions mainly about the rst manifold mate

i wanted to know whats the point at which they become restrictive on a 1.6 cvh turbo

crazycage

isnt the efi inlet the same inlet that is fitted to the fiesta turbo tho??im not sure when they become restrictive tho .

J1mbo

iTrader: (1)

probably, only difference being the throttle body, but got rst efi inlets at work anyway, like i say just need to know the point of which to change to a proper inlet

im sure someone on here knows

crazycage

couldn't you just get some free dyno time off your old man and test them for everyone ?? or you guys far to busy for that lol

jim we all know your building a big power CVH

J1mbo

iTrader: (1)

the dyno is always busy tbh and i dont have an engine to test it on

when i do sort an engine if someone wants to lend me a proper inlet ill be more than happy to do a back to back lol

J1mbo

andy, i wish mate, insurance coming up cant afford petrol to get me around let alone a cvh to waist it

crazycage

if you were to do some testing i would be willing to send a inlet that i have made for a friends big power cvh ,you could keep it just let me know how it done .

J1mbo

iTrader: (1)

depends what sort of power your wanting to test it on bud ??

crazycage

around 300hp no worries if not would just be nice to get a pro's opinion back to back

J1mbo

iTrader: (1)

tbh im not gonna be doing anything at 300hp 240-250, could do a back to back on that possibly

jimbo ive seen a few big power cvhs with cosworth manifolds modded with cossie tb!

J1mbo

iTrader: (1)

yes ive seen would work well i bet !

crazycage

let me know nearer the time and i will send one down no harm in testing it at that power purely as a back to back

J1mbo

iTrader: (1)

i will do mate will be interesting to see the differences even down low ect ill drop you a pm

jim

crazycage

has anyone got a pic of one as the ports are the wrong shape for the cvh be interested to see how they got it to fit??

J1mbo

iTrader: (1)

yeah would be interesting to see ill have a look about

sorry to jump in, give simon a shout at sitech for a go of their inlet, im getting one for mine so it would be very interesting to see what differences there are. Ive heard that out n out bhp isnt the main gain but the response etc

J1mbo

iTrader: (1)

yeah throttle response is more important to me but i dont wanna spend hundreds on an inlet where a standard one will do !

this one is what most are based around

bezo

the cossie inlet is miles off a cvh head, so have to make an adaptor plate. then rotate the elbow, making another plate for elbow and the TB ends up sitting up near the air box.

ive just taken mine off to replace it with one of our inlet plenums. no reason just wanted one. cossie inlet stood up to the job.

ive got pics somewere, will post them up later.

bezo

just out of interest, once the TB is fitted would that not foul the brake servo?

have i heard that the mfi inlet flows better than the efi on the cvh??

My ZT16v had 380bhp using a T4 with greys and an EFi manifold from a CVH. This flows very well and was designed by fords to be better than the MFi manifold which had different length and size ports. Meaning that the end clyinders 1 + 4 would always be unequal. I have not reached the limit of the EFi manifold yet. I doubt i will be able to, without getting much higher power figures which my engine will not be able to produce without spending money on head work and cams etc. At the mo it is totaly std and cost £125. The engine rebuild with steel rods and pistons cost £940. Inlet cost £30. The most expensive part was the turbo and intercooler.

So there is no need for any bent and welded sheets of alloy (Expensive ones at that) to be thrown on to my engine and be called an inlet manifold.

no it's fine got a cossy tb on it and then an 90 elbow to face intercooler and for the price compared to others (several people wanted best part of 500 for full inlet) i'm well chuffed as the lad who designed this also designed several others for well known tuners

hi jim i think the cvh efi on a mid tuned engine is about 300bhpmax @ 20psi , mine ran a rs1800 inlet on my first zetec turbo running very similar power , like you said if ypour engines not all about power then it will probably be fine , however if you add a well designed zero loss inlet then throottle response would be vastly improved upon, i would say buy a area six zero loss inlet as this inlet has many hours of flow bench testing and is provern on many high powered cars , may cost £750 but you will be well pleased when you see one , a work of art , plus he uses your old mans dyno so iam sure he could sort you a decent price out.

cheers paul
