Re: loss of rev limit

Is that a seat of the pants guess-timate or on the dyno?

I wondered this myself about my RS, I have no idea where the power is strongest, its all bloody good above 4 grand. Also not sure how the couple mods like cam, extractors, Weber, etc affect it as well.

I think I'll wait till I rebuild the engine in 6 months or so to stick it on the dyno and really find out where it's at.

What are your cam specs??
Also, is the cam timing spot on?
Does the webber flow enough or does it need bigger jets?

What plans do you have for the rebuild? Stock, mild or wild??

I could guess, but that's all it would be, an (semi) educated guess...

Could be any number of things really.

Cam specs? Fuel filter? Fuel Pump? Airflow (any head work been done)? Transmission problems (or in fact any of the drivetrain)? Distributor problems (point bounce, worn points, any number of other possible problems)? Spark plugs not being gapped currectly?

If it was me, I start with the easiest ones to check - and if you havn't had the points replaced in a while, I'd go the whole 9 yards and replace the points, leads and spark plugs, even if it doesn't fix the problem, it would be far from a waste of time. Then check out the filters, and probably replace them (again, never a bad idea), before checking anything else.

But it sounds to me like the distrbutor, and more specifically, point bounce. Does it seem to rapidly lose power above 4500 rpm, or just doesn't want to rev past that point?

But hey, I could be on the entirely wrong path here...

Probably mild, it already is mildly worked so a bit more than what it has, but I don't want to detract from the authenticity. It has the stronger German EB block so it can handle some extra punch easily.

Hopefully getting a set of twin SU's for it this weekend, just see how it all pans out and what comes my way.

It won't be going for the Summernats Top Ten or Horsepower Heroes though, no fear of that. Well, thats the current plan!

i can get it to about 5000 rpm but barley, and also, you can feel the power drop off as the tacho hits just afta 4000rpm

also, are there different types of eski gear ratios????

cause with all me other eskis i had ive been able to hit at least 90km in 2nd gear but with my latest one it barely hits 60km.

just thought i should ask

oh one more thing, i have no idea about the cam, it came with the car and the previous owner didnt know the exact specs on it. plus, who do you find out if the cam timing is right?

Yep check the simple things first,timming ,fuel/carby..
If you have recnetly fitted the cam the cam timming could be out a tooth on the timming belt,use the tdc marks on the crank and cam to confirm this.then check the the ignition timming,with a timming light,clean and set your points gap the the reccomened size they may be closing,then check the plugs for fouling and reset the gaps to the manual cant remember of hand.
Carb/fuel...Make sure both ports are opening when you give full throttle and check for fuel spray from the jets to the throats of the carb.
Is it missing at any point of revs?
Ive as per the other guys have stated.
The 2ltr pinto is a great/torquey engine and is very simple to work on,in fact Im selling my xr6 ute to drive my RS2000 daily because I love them so much.

Interesting as 4 grand is where the fun is just starting in my engine, and will hapilly wind out to 7 grand plus.

And I am not sure about gearboxs, but I know the RS2000 runs a different diff ratio to other Escorts, from what I have read.
