Had a Rolling Road test done as I've just had the Cambelt changed, pretty good power figure, not sure about the torque curve. Its not very smooth...

 

[AYAT]

not bad but torque curve looks a bit strange

 

[Joss]

Not ba mate. Mine made 256.4 bhp as standard. It's a very worn engine though :lol:

 

[BeautifulBusso]

Good result, mine made 257.4bhp with no mods too! Kinda wish I kept it that way :lol:

 

[silvervalver]

Considering its over 30 degrees that is very good

Just had to be one more didn't you :lol:

I find it impressive that these cars are still producing the same amount of power they left the factory with after 10 years.

 

[Ruskins]

Anyone got another stock printout I can compare this with?

 

[Joss]

I'll find mine tonight for you.

Here are Gotcha results:

Anyone got those standard printouts in BHP and lbft ?

 

[BeautifulBusso]

I'll sort mine out now

 

[Joss]

Here you go mate

The reason your torque curve looks crazy is because of the scale, no other reason I reckon. It starts at 155lbft and tops out at 210lbft - a scale of 55lbft per page.

Joss's on the other hand starts at 0 and runs to 260lbft - a scale of 260lbft per page. You don't notice the peaks and troughs so much because they are 5 times smaller on Joss's graph.

Maybe you should call them up and ask them if they can re-plot the data onto a graph scaled from 0 for both power and torque.

Mine made 191.4kw (around 257bhp and 250lbft).. That's right.. Torque figures were way more than even modded GTA's on the same Dyno.. Don't ask me why..

And yes the graph looks odd due to scaling.. But the increase in torque after 4000rpms you will find on most Busso's.. One of the nice characteristics of the engine.. :thumbs:

That's really good torque! Mine was at 220 ish as standard, it makes 250 now with a remap and Alafholics exhaust on a 3.2.

I might have to have a go in yours at next Oxford meet Nigel

Don't know if you know, but there is a rolling road day coming up at Surrey Rolling Road, it's so we can see what the GTAs and other Alfa's are running on the same dyno :thumbs:
