Zetec rolling road session... on the money?
Just had the call from the rolling road to say my car is ready to collect.
Replaced 1.8 pinto with 1.8 zetec (plus bike carbs) over winter. Also put in 2litre cams.
All set up the guy says it has 105hp at the wheels.
I wasn't expecting hundreds and hunderds of HP (i'm realistic) but is this about right? Not sure what to expect for trans losses etc
Your thoughts...........?
Thanks
Dan
EDIT came to £100 all in which i thought isn't bad at all. Sleaford Mini Centre in Heckington. Nice bunch of lads 01529 460049 (free plug too

If I'm not mistaken, that's only about a 2.0 standard Pinto power. Seems a bit wrong to me.

doing some fast maths and assuming high end transmission losses (20%) thats 131hp at the flywheel.
I dont know what these engines make though.

That looks like a bit low on power in general i would expect.

What does it go like? That's much more important than any figures from an RR session.
I never had my 1.8 zetec checked but it was considerably more powerful than my 1.8 CVH, and my Zetec was fairly well knackered.

What can i do to make it better? Timing?
Megajolt has been set by them too. How can i get the cams better lined up? Or wouldn't it run right if they were out?
The guy at the RR said it made good power.....?

The one thing I have found using numerous rolling roads is that no 2 sets of figures are ever the same 1 rolling road may say 100bhp whilst another
could say 110bhp, as said previously if it's quick and your happy then £100 well spent.

it could be that the cam timing is slightly out but the figure doesn't sound too bad.
take the bhp reading with a pinch of salt as it can vary due to atmospheric pressure engine temp fuel etc etc.
go out and drive it. if it feels faster and drives better then you have achieved your main goal.

Hard to say as the rolling roads all seem to vary on calibration. Some seem to be set to give "good" results. Whatever the calibration
it's all down to set up. It's just numbers... it's the way it drives that matters.

Seems about right to me, but absolute numbers from a rolling road are pretty useless since there are so many variables, e.g. slightly soft tyres have
a big impact on power at the wheels.

Seems low to me, had mine on the rollers at BB for a run up after usign them and a gas analyser to get my zx9r carbs set up.
So, my 1.8 with 2L cams, MJ + ZX9R carbs gave flywheel 155bhp.. 125 at the wheels.

Yeah got it sorted ash thanks 
posted on autosport forum and got replies from nitropixie and brent p on how to test the chips and circuits. Ended up being a dodgy solder. Heated it
and then it was ok. Daft problem which is often the case.

Depends on soooooooo many factors- plus unless you've got the figures from another rwd 1.8 Zetec car run up on the same rollers you
haven't actually got anything useful to compare it against! I've had engines run up on a rolling road I knew was pretty spot on showing a
power output a good 20bhp lower than one I didn't trust to be accurate (nothing to do with the operator btw, the 20bhp more was on Pete
Baldwin's' of Mini Miglia fame and he knows what he's doing! ) So when you pick it up have a look at the printouts and if
you've got smooth power and torque curves and if it feels faster it's a result! Probably the only thing you wont have is a piece of paper
with big numbers written on it to brag about down the pub

Ok, off to pick my baby up now. Will let you know how she drives.
I'm less concerned about the RR figures now, it seems that they can vary...
often wondered if they were calibrated or if they were just near enough. Pinch of salt taken ash

Glad you got it up and running ok, would say its a bit low, but as said above lots of RR varables 1.8 with RS1800/136 2litre cams standard would be
around 130 at flywheel, so with carbs may expect bit more than this, can you confirm they are 2 litre 130 spec cams, not 115cams?. As for checking cam
timing this is quite easy by wipping the cam cover off and checking grove in rear of cams. ive got a couple sets of 130cams in you want me to measure
lift on them, which is the main differance i would think between 115&136 cams but someone might be able to confirm.
Have you still got the track day booked for Tomorrow?

Sounds about right to me, the uprated cams are 130ps so over 100 at the wheels doesn't seem too low. £100 all in is realy cheap for a RR
session, if you suspect they haven't done a good job then take it elsewhere, but it will cost you a lot more money to get very little if any hp
gain! All ihmo of course!

Hi
The 1800 Zetec with the 2Ltr cams fitted is more or less Std 130spec. Now this engine is used in that format is so many race championships it's
untrue. I have yet to hear of any rolling road results below 150 at he flywheel. Thats with the cams timed in as per ford on the 5mm bar.
With a little cam timing those 150 figures will rise to 165-175 depending on who's road is being used.
The only thing i will say on though is that all the above figures will be found using reliable ecu's not mega systems. This could quite easily
be where there is some restriction or limiting of more power being released.
Cheers Matt

cant be a lot of restriction with megajolt for ignition can there matt? At the end of the day its a fully mappable 3d ignition controller - fairly
simple bit of kit but with quite fine controller over the spark.
Not disputing your position, more interested to know what you think as someone with a lot of experience in the field.
cheers.

Got home. It it un-be-f***ing-leavable!!!
Such an inprovement over the pinto. It is really really quick. It was actually 110 at the wheels. The figures mean jack TBH because the smile factor
is 11
Sounds amazing on bike carbs. Can't tell you how happy i am 
Cadwell tomorrow... a good week

Don't worry craig. It turned out to need an expert opinion from brent and nitropixie. All help i have recieved from these pages has been like
gold dust
The rolling road made such a difference. Had a sneaky drive before it was set up and now it's a woooosh machine
First time driving with a helmet today too. Not sure if i like it better that wrap around glasses but it's safer and wind noise is loads less!!
Also got to get used to it before tomorrow

LOL, play nicely Matt we have no idea on the actual spec/mileage of the engine or the reliability of the rolling road concerned - if it works
better than it did before it's still money well spent - and at least it gives Dan a benchmark for further improvements..... lets wait to hear if
he thinks it's better/faster before saying it's not powerful enough - dialling the cams in might well help but now at least he has
somewhere to go for a comparison 
Ah well there you go, typed too slowly - result
