my s2 is running 191.9 bhp, was just wondering what i need to do to gain more power, without changing to efi, is possible or is the next stage efi?
ive just bought the car, and running at that bhp, i would think its been cammed, ecu, 31, k&n.
any ideas guys? thanks

It's certainly not ATW with that spec.
As Milesy says a Stage 2 T3 will see you over the 200bhp barrier, but it's if your old MFI fuelling system can accurately deliver enough fuel is the question.
IMO EFI should be the first step on any RST nowadays as the metering unit is 20+years old and unreliable fuelling can kill an engine in a second on a turbo charged car

why?
why are alot of people suprised wih mfi set running a little more, with correct set up and propa parts, mfi can run it still!

come on lads, mfi isnt that bad. Mine hasnt run for a while but definately has more than 191bhp at wheels on MFI. Not for one minute saying MFI is reliable or worth keeping, im fast looking like cossy management on mine when I can be arsed, just dont be so quick to write it off.

ive had a s2 running 189.9bhp atw at 23psi on mfi ...... so un sure of flywheel figure
full spec was
stage 3 t3
stage 3 big valve head
piper fast road cam with duplex springs ect
standard bottom end
turbo systems chip
arp bolts
3" exhaust system and down pipe
and modified metering unit with s2 black box on it

it won't be at the wheels mate, it will be a calc from the wheels to represent the flywheel power.
for reference my approx 180bhp at the fly use to push type-r's out of the way, you have a big weight advantange and along with the torque type-r's ain't a problem

ive had like 12 rs turbos now so i know what an rs turbo is like at 180bhp at the flywheel.... cos my first two where at that power but this one was the best spec you can get before going for after market management.
go on the nms web site and look at there stage 4 with 220bhp and only 18psi of boost.... mine was running 23psi with modified metering unit.

Does anyone offer a drive in / out service for going from MFI to EFI? or going from MFI to cosworth management? Im in Plymouth and wondered if anywhere would do this that is remotely local?

I dont think that mfi is a bad system aslong as you look after it but i wouldent want to run much power using mfi, alot of people will agree that efi is the first step for big power.
as for a drive in drive out mfi - efi jano oddkidd www.oddkiddcreations.co.uk is the only person i know who would convert a system.

Everyone has their views.Me personally be running around 250Bhp at flywheel with my fifth injector.Ive had no problem with mfi.Ford never built them to run stupid amounts of fuel.Hence the oldskol Fifth.efi is great,but then so many people do it.I try not to follow the crowd,go down my own route.For the worse or better.You cant floor the efi,its a good system.But some of us like taking the risk.If your after safe and money saving on fuel,plus around 17 to 20Bhp more than mfi,go efi.

I think you have done really well getting that power out of your motor mate so well done. On your last statement though saying efi will only give you a 17 - 20bhp gain is a little off base in your situation. Sure at say sub 230bhp this may be true but now you are getting towards that you simply can't control the fuel accuratly at these sort of boost levels, imo injectors are a must when reaching these sort of boost power levels to ensure each cylinder is getting the precise amout of fuel, where as a firth injector may give a nice full power figure, the efi will give a nice power figure/drive no matter what the tps etc as each load site can be adjusted unlike MFI. With efi you can get both huge gains in bhp but also maintain a drivable car, not to mention cold starts etc, my escort was a shylittle thing on a cold morning.
I would say if you want to be different go efi but try something unconventional.
Kelly Baker - Jamsport do a drive in drive out service using their Gotech ecu, picks the cps off the dizzy and they install everything else such as modified injector rail, fuel rail, injectors etc. Price is around Ł1600 if memory serves me right.
Mtech Automotive also do a converion I think.
As said above Jano @ Oddkidd Creations another efi/cossie management guru

Yeah i was going by a post on here,that saw a 17Bhp increase over mfi.Thats just an example :-p .Im happy with my motor and just like to state,im not currently running the 5Th injector.John who owned the injector had 270Bhp but turned it down to around 250Bhp to save fuel lol.Ill add another injector if needed lol.But then thats just stupid.Im currently running 196Bhp on standard cam,stage 3 head big valves,at 14Psi.212Torque.With the aid of custom cam,boost increase and fuel and uprated turbo,it be intresting to see what i get.running standard t3 at mo.

Fair enough, if thats genuine power then that really is amazing from your spec/boost!!! another freakish engine ![Smile](https://passionford.com/forum/images/smilies/icon_smile.gif)
I got 185bhp from 14 psi but that was a stage 3 engine/turbo etc :-(

Casting mind back many years ago, didnt Steven_RW have a freakish CVH that had very few AVA mods but made good power and times to back it up, consistantly too. Know we cant use that for the MFI reliability arguement but for the performance of it I see it as valid. With a new loom and refurbed metering unit I cant see why MFI should be ruled out as a budget option. With the 5th injector (and a few NMS mods)on mine I loved it. AFR setup nice and went very well.

Yeah def a freakish engine.Had it in bits and come across nothing to tell me why.It only runs on shell v-power.anything else runs like crap.Normal unleaded big no no,was pinking well bad.Yeah i dont see why not,mfi good considering the age of the system.many cars back in the 80S used same system,even V8s,porsches.If i had another escort,i probably would fit custom managerment.

I think the bottom line with MFI is.. Unless you buy a brand new EMFPR, Flap position sensor, fuelling ECU, and metering head, you cannot guarantee accurate reliable fuelling which is just too risky if you've spent good money building up your engine!
If it's an old shitter then fair play bang it around until it melts then build a fresh engine with EFI

Well at least you can turn your EMFPA down so that the metering unit is fuelling for upto 7psi as Ford intended (returning some economy and response) and let the 5th do the rest! This will give you a much better chance of reliability and if your using a MF2 (which I guess you are) you can have slightly more accurate fuelling from 7psi to whatever you choose to run.
For people wanting to stay MFI it is the best option really
