15.01. 95mph terminal.

Top end its a little down on last time but the low down acceleration and traction is much improved, it just needs a new engine tbh

[Excursion]

Get a 2.0 in there mate

[~nomad~]

He is on the hunt for a 2ltr now. Engine is very tired.

Unless jony will sell his engine, with the mods this one has bolted to it and his uprated plugs and leads we could be looking at a very real, Welsh 180bhp!

Got one kicking around??

That engine will break into the 10s on the strip, this is a must.

It might just be me though but I kinda feel the 2.0 gives up easier top end than the 1.8s?

No mate, but they're hardly difficult to find http://cgi.ebay.co.uk/FORD-MONDEO-2-0-l ... 27b91cd2b6

I know of a few in various yards around the country.

[Rhinopower]

My 2.0 I had in my escort really came alive at the top end, might be your cams?

No way mate, I spun bearings in one of my first 2.0 conversions as it would pull and pull and when I looked down I was past 7k all the time. I say this a lot but there's really no comparison between a decent 2.0 and the 1.8.

I've been in so many 2.0 conversions that either aren't done well or are done on the cheap - bad sensors, cheap plugs, non-HO inlet etc. and it kills them.

[Tweek]

This is true. I've had quite a few things which have been slightly "off" recently so before Combe I'm going to try and get everything fitted/running properly and go from there. Good to know I'm wrong though, gives me hope lol.

Make sure your cam timing is spot on also, it's easy to get a tooth out.

[Tweek]

That's one of the problems I need to address. The Piper cams I bought to try and improve keep leaning back/forward very slightly. Couldn't get it right unless the belt was tensioned so it whined (using the proper tools). I have verniers to fit to attempt to cheat but whatever result I'll feed back when I update my thread

It's worth getting the Verniers dowelled if they're not already.

[jonyb4]

dunno if the situ has changed wayne but you always used to make it seem that your engine wasnt running at its best, its probably something stupid like a knackered sensor

[Tweek]

situ has changed, but thanks

[jonyb4]

thats a good thing

All the things im pretty anal about! I've got the st170 plugs as they are the next heat range up. Cheap leads too is another brick wall i've experienced before, cheap ones held the car back, particularly at top end, bosch leads were much better!


Tweek, are your cams set up to the suggested advance/retard as advised by piper? Im still keen to try out running the 105 zetec exhaust cam.

see now that has me worried, im using cheapo leads simply because i was worried my ford ones were causing ill idle, and as theyre a blue instead of black


also ive heard using a 1.6 exhaust cam in a 2.0 is a very good method for unlocking power


you say its worth fitting a 105 cam in? i have a pair of these and 1.6 cams to hand

[Rhinopower]

105 exhaust cam gives more torque but less bhp.

I've had a set of cheap leads before that at night looked like a fireworks display under the bonnet with the leads arcing on the rocker cover!

haha oho, were they sillicon insulated or just litrally cheapo ones?


i know the 130 spec 1.8 is down on torque compared to a 105 spec, and is to blame
guess its a try and find out sorta thing really

are you gonna try it?


must be the same if you fitted a 1.6 cam to a 2.0 then

[~nomad~]

I thought you had uprated leads Jony?

[Rhinopower]

I am going to do it, the 105 cam would have the same effect on the 1.8 or 2.0, im going to do it when i slap my 2.0 engine in it.

As for the 1.6 cam i have no idea on profile/lift/duration and what it would cause so will leave well alone.

[Excursion]

The 90 or 105 cam will kill your power. They are used in a Turbo application to aid spool because the short duration causes more violent exhaust pulses which drive the Turbo harder, and the benefits of that outweigh the shortfalls of a short duration.

Personally I would stay well clear with an NA engine - revs are where your power is!

[jonyb4]

you have a point there mark, a Honda Vtec engine for example

[jonyb4]

I thought you had uprated leads Jony?

theyre 8mm and sillicon coated so technically theyre uprated from standards

[~nomad~]

how can they be uprated and cheapo?

[Rhinopower]

Mark. The 105 exhaust cam was suggested to me by Ian howell over 5 years ago (god I feel old now!)

For a turbo application surely? I don't get why you want to gain torque from an already pretty responsive engine and sacrifice top end which is where the fun is.

[~nomad~]

not on trackdays and 1/4 miles thou, pesuming when you say top end you are relating to top speed. Dunno about Brian but for me 120ish in a fiesta is quite enough

[Excursion]

RPM mate

[Tweek]

Just chucked them in factory setup the top-end thing was there before this though. I am looking into it though, my main aim for pre-season is just to get everything running/fitted properly

aye but the thing is, if the power were to kick in a bit sooner surely your waiting less time for it, making an overall quicker car?

im probably out of my league with what im saying here,, but i know how it is with the 1.8, the power is mainly after the 4k mark


personally id recommend a four branch ryan, they open the rev range to about 3-3.5k and it will start pulling fairly well from there, and then ofcourse get more progressive towards 4k

best way really is to try the 105ps cam and see, if its poo swap it back with the 2.0/RS18 one


i found that linked thread quite interesting

[~nomad~]

car has a st170 manifold, doesnt need a four branch

[Smo]

Pretty sure he's already got a 4 branch manifold on there! It's the second one now, is it not?

With regards to choosing cams for better torque, what you need to remember is, if you're doing 1/4 mile runs and other timed acceleration events, you're going to be pushing the engine almost to its rev limit, in which case, you're rarely dropping below 4500 to 5500rpm (roughly depending on gear ratios!). 2.0/1.8 130PS cams are quite ideal for that, and are probably all you need until you start running some sort of improved air intake, such as throttle bodies or a far better plenum.

My 1.8 has never felt like the power tails off at all, and in both my power runs it had when it was a standard 130PS setup with cast exhaust manifold, cat, etc, the power figure was still just(!) about climbing at 69XXrpm when the operator wussed out I didn't care if it went pop

Whenever I've done any timed 0-60s, I've always pushed mine to the limiter (well, a smidge before, so somewhere around 7100rpm) and it's always pulled all the way there just nicely Stick with the 2.0 cams!

[jonyb4]

ah it has the manifold?

not much in that area to improve on then lol

like simon said its intake next or better timing and ignition, verniers?


ive been meaning to alter my focus inlet to fit, to see if it makes a difference, but not got round to it yet, aparently is has a smoother flow design than the H.O cast inlet

[Rhinopower]

Today im picking up some ITB's which are normally fitted to another car, pics to follow including manifold mock up.
