Yeah where abouts in Livingston. The Scottish region are talking of having another dyno run next year.

CLUB
We had one at Dastek in Dalgety BAy not that long ago.

Colin and mines were pretty similar in both torque and BHP figures.

A good day out and all for �20

Gary, What exactly were the power/torque figures for you car? I too have a Sport Evo and would be interested to know.

Thanks

Steve

Well I've had mine on the rollers again this morning. Since the last time I posted towards the start of this thread I've done the following:

1. Replaced Scorpion exhaust with Supersprint system
2. Replaced distributor cap
3. Replaced rotor arm
4. Replaced spark plugs
5. Adjusted valve clearences
6. Re-synchronised throttle bodies
7. Re-wired ECU to enable 98 RON open loop map

First off he did a compression test, which showed no problems. Then Clive hooked up his diagnostic kit and did some exhaust gas and ignition tests at idle and low revs.

Finally he did two power runs. The numbers speak for themselves:


203.8 bhp @ 7,108 rpm & 169.2 lbft @ 5199 rpm

About 163 bhp at the wheels, so thats 23 bhp and 26 lbft improvement, and boy does it feel it on the road!

Steve sorry for not getting back to you quicker, been busy.

That map looks wicked.

I would say that the look of the curve says the wheels spinned on the rollers at around 2000rpm as apposed to that being a flat spot which is usual.

Very nice.

That sounds fit and healthy. Is your car standard?

look at garys signatue chippeduk.

Tim your torque figure doesn't cross at 5,250rpm  Does this prove the previous theory wrong or is there something funny about that dyno chart?

I only just realised that !!!

There has definately been a mistake here, they must cross earlier.

If you look carefully the torque scale starts at 55lb/ft and the Power starts at 10bhp.

At about 5252rpm the power is about 170bhp and the torque is just less than 170lb/ft so it is not too far out.

There is no mistake, that theory only works when both torque and bhp graphs are on the same scale, which this isn't.

Ah I see!

That seems a better way of displaying the torque graph.

Seems to be producing the figures a bit higher up in the revs than stated in the standard figures. Wonder why that is? Perhaps the exhaust flows better at higher revs, although your not losing any power lower down the scale. Curve seems nice and smooth.

As far as I know the car is standard. It has had a new head and block from BMW in June 2002. I don't know if that would have anything to do with it.

I must confess that alot of this goes over my head. I was also running normal unleaded at the time of the R/R session, but was advised to use |Optimax which I have being doing since.

My Sport Evo has had a new block and pistons along with a full rebuild less than 6k ago. It will be interesting to see what it puts out. It will be getting at least a re-map maybe even A/N when I get back from this job in April.

What was it putting out at the wheels?

Sorry to sound sceptical, but 250 bhp in standard form is surely incorrect? What was the factory quoted output for this model?

I thought a couple of threads ago, there was a conclusion that it was only worth quoting rear wheel figures. Anything else just adds confusion.

Yeah, i'd say there must be some different cams in
there Gary. 225bhp seems to be the average for a
standard sport.

Have recently had mine re-mapped after engine rebuild and alpha n, have not got a scanner so can not post the dyno, but i was really pleased with the results -

    266bhp - 219lb/ft   (  at the flywheel )

On the dyno it says ( MPH ) surely this can't be correct as mine reads 219 mph     !!!!!!!!!!!!!!!!!   ANYBODY ?

( Go on then uwe )

Colin Gallie was there and has a Sport evo engine in his 2002 and he was putting out about the same. He seemed to think there were different cams in as well.

Although I have'nt put them in and I don't have a reciept to say the prevoius owner did either, it's not beyond the bounds of possibility.

Unfortunately I don't have a scanner so can't post a pic of the print out.

I think the guesstimate convertion for the BHP at the wheels were about 210 BHP.

Which I was quite pleased about as it is standard as far as I know.

As I said alot of this goes over my head, but that is what my car dynoed at at Dastek in Dalgety Bay in Fife.

I will try and take a photo of the print out and post it up and those in the know can tell me if my engine is healthy or not.

Intresting thread,

My track car has just been re mapped to sort out a few gremlins and the following was achieved.

269.7 BHP @ 7397 rpm and 202lbft @ 6303rpm.

When it was in 2.0l form it made 218.8BHP @ 7945rpm and 158.2lbft @ 6694rpm. This was more than my standard 2.3l road car from a 2.0l S14. Where those 320is boys, as I may sell my 2.0L engine, which I currently have stripped for more goodies to go inside.

Both these engines  used the same head with schrick 284`s, MBE, CF air box.

Still is more room for improvement, and by changing the cams should hopefully see target of 300BHP as the 284`s are what is now restricting the engine. With wilder cams comes the cost of shim under and buckets so will live with it like this for a while.

I will try and post the printouts tomorrow once I can scan them. Uwe also has a copy, so he may post printout of the 2.5L if he reads this.
