Just got this through the mailfrown

It appears that due to conversion to Rhd the right hand side exhaust manifold is different and it's costing us 5PS....

Oh well hopefully the Borla will make up for the slight loss......if it still fitshehe

I just got this too! It has too be more than the steering as they got round it the other way, surely it is reversable, how will this affect my after market exhaust systems from the cat back? Do we get any money back as well, little bit annoyed right now, going to give them a call

A mere 5bhp.

You'll get more variance from that using different brands of petrol or from ambient air temps.

Don't think I'l be cancelling my order as a result!

My biggest concern is the exhaust? Will it still be the same from the cat back?

Yeah, I'm not fretting... a decent meal on board would mean more of a BHP hit.

For me, this is more importantly a fairly positive communication from Ford - at a time when we need it most.

Now get my car built, on that boat and stop writing letters.

As has been said 5 BHP is neither here or there......but if I'm honest, I'm more concerned that they've only just realised that either the RHD steering column, didn't fit with the exhaust manifold, or the exhaust manifold was in the way of the new RHD Steering......

In this age of computer design etc, I would have thought all this would have been established ages ago....

It does make me wonder what else will have to be "tweeked" to get the RHD bit to workscratchchin

Let's hope they've realised we need pedals on the RHS as well as a steering wheelhehehehe

My worry is whether the Borla after market exhaust will fit to the new manifold

I can't believe the manifold will be any different where it meets the big resonator in the middle, so should be fine....

If it isn't, I have a grinder and a welder, and I know how to use embiggrin

I spoke to ford head office, so...

1.) It's been moved for the steering column, (they would've had the same issue on the other side on a LHD as it is a V), it isn't the steering Column it's something else but they don't know

2.) they have tested the new manifold and say the torque curve isn't affected... But at the top of the rpm range you lose abit more, BUT get this! So how many cars have Ben tested not all cars come out the factory the same? Well they don't know...

3.) It will be identical to the U.S. Spec from the cat back, good news there!

4.) Performance figures won't be any different, hmm not sure if I believe that, especially with the answers prior

I stuck it to them abit and got 15minutes of Erm, Uhm, Ahhh, I don't know, I apologise... There is a real lack of knowledge,

But clearance is only half the story. Despite modelling in CAD, when you build it you may find that the bits fit, but then heatwash from the manifold cooks the column. Given the steering is electronically adjustable, conduction down said column could then fry the electronics etc.

I expect that whilst lots of testing will have been done on the LHD, there will undoubtedly be a few 'tweaks' required for RHD. This is one.

At least they've been upfront about it.

Yep...can't knock em for thatthumbup

The other thing of note, is the "12 weeks" delivery from leaving the plant..... 3 months seems a bit ott once the ship is on the water..

I'm hoping this is worst case scenario and things will improve, once things get moving.smile

Depends where other components are as well such as the starter motor.
Maybe it's just to pass sound tests but this sounds better....4th gen Euro Z28 only made 288 bhp compared to the US 305 but certainly seemed no slower once a louder exhaust was refitted.

Well so much for all modern cars being thoroughly tested. CAD should have prevented any clearance issues and surely they have some kind of heat-sink model to ensure vulnerable components are shielded or positioned away from potentially damaging heat sources? ..... maybe they used the same heat model that Ferrari used when deciding on the glue for the rear inner wheel-arches on the 458! biggrin

So a 5bhp reduction doesn't make a difference? ..... finding that hard to believe. If it doesn't make a difference, why is it there in the first place? Do you think the 1% reduction in power will be offset by a £500 (1%) price reduction? smile

I like your thinking! £500 it is biggrin

We are getting a mere 416ps whilst the U.S. Version just got another 10ps on top of the original figure a few days ago, they're getting more whilst we're getting less, by the time the cars get too us we will be in double digits :'D

Ok - more accurately, 5bhp doesn't make a difference 'to me'.

If you can tell the difference in a car already producing more than 410bhp, then you should probably give Ron Dennis a call wink

Besides, mass produced cars aren't exactly known for 100% accurate in terms of stated output. I expect there's around that variance between the engines coming off the line.

Good luck getting your £500 back - let us know how you get on wink

Stig,

5BHP is enough, you will feel it, especially on drivability and responsiveness along the curve, to get the best manifold it is an exact science and mathematical equation, you can notice 1BHP quite easily, also 5BHP is quite a lot considering it's now 25BHP lower than the U.S. car as they have just received a 10BHP increase, people have a reason to be angry as they have signed up to something and now ford are changing it mid contract,

As for you comment not every car comes out equal I agree, however what you may not appreciate is that no one seems too know how many cars it has been tested on... Where have these figures come from... No one knows

Thus! You get a good performing engine with the new manifold, not such an issue, you then compare that to a poor engine with the U.S. Manifolds and its 5BHP, how reliable are these figures and are they representative of the cars we will receive

Received my letter yesterday as well . This has just added another question of doubt in my mind , having serious doubts this morning about pulling my order and importing one myself !! Going stateside in a month , going straight to a ford dealership to ask a few questions !! Might even have a look at the camaros if there's any to view ?

I've just been over there, Camaros are two a penny, worth looking at all the options I really like the challenger and disliked the Camarillo which isn't what I expected but hey! Pictures and flesh look very different smile

On a more serious note! We have no proof of the data we are being given I want too see the curves, and proof of the figures we are being given, I want too know how many cars have been tested as well,

Considering they are meant to be a company coming back into Motorsport...
