Dyno Power run, very happy!!
 

As some of you may know I took my ZS for a dyno power run to determine the stock BHP and torque prior to doing anything to the car.

Turned up at Noble Motorsport earlier this morning and got the car put on the rollers, a few checks were done to make sure everything was running rite before the actual run. Had the proper run done and everything was spot on! Then was presented with my power graph and was very very surprised! lol me and my mate both were.

A stock ZS 110 (1.6) figures according to Parkers and Rover should be-

BHP- 107
Torque- 102 lb-ft

My so called stock ZS 110-

BHP- 123.0 at 6729 rpm
Torque- 108.2 lb-ft at 4960

SO WELL HAPPY!! just gotta figure out why its producing those figures from a stock engine and car!! I asked about over readings on the Dyno but the technician said they are spot on as he had a stock MX5 on the other day and the figures were bang on. I am going to give it a 2 BHP leniency but still very happy.

Let the modding begin lol

Sounds like the previous ((One carefull woman owner)) new what she was doing !!
Good result you got there mate..

Save you a few bob, already got over 10% power increase, good choice of car.

:):):)

You sure you not got a 120?! But even then its a good result!

Might get mine stuck on one and see what its doing :)

Thats a good result from a 110!

Thanks everyone! very happy!

No mate definitely the 110, if I had the 120 engine the torque figure would have been higher.

I have been told by a mechanic friend and also the dyno tech man said that every engine produces different power etc. It can depend on how they are assembled and how well the parts are working with the generic map. Also been told that the paper figures mg-rover put out there were usually acquired by dyno-ing the bare enigne without ancillaries. It can all affect the overall power supposedly.

That sounds like a really good result Tom! ;)

i may get mine on the rollers at some point would be good to see what she makes! :)

Cheers mate :)

Obviously they are not 100% accurate but they are the best guess figures you will get I assume.

All manufacturers bench test engines, they are connected to a dynamometer.Just like this Lotus K Series getting tested
All engines are different, no 2 engines are ever the same even if you have built them side by side using all the same parts.

Can that affect there power output though? I expect the Dyno today was over reading to some degree because surely a ZS 110 that has bench marked at 107 BHP by Rover cant be producing 123 can it?? stock too??
