is 130 bhp at wheels about right for a 2lt zetec its got honda blackbird carbs newman fast road cams no cat.
the engines are
136 BHP 93-96
130 BHP 96+
but i found a 2L in the scrapyard with 139ps on the cover so now i have the head off that. so your already got 130.i dont no what you will have with
the carbs and cams and no cat but you gotta have about 150

arent manufacturer figures always flywheel bhp?

i think this engine has 100 bhp at wheels in a mondao
yep quoted at crank.
2l with carbs and good ignition should give 165 @ crank, add the cam and it should be 175 ? shouldnt it ?
Take away transmision losses ect and I would still hope for a tad more than 130 @ the wheels.
I am hoping for at least that with out the cam.
I think it depends on the dyno you use ?
running omex ecu disapointed with 130 bhp at wheels +25% transmision would give 175 bhp at fly 175
- 25%
= 130
its not enough

in my hands that would be deadly i'm bad enough in a scooby
So how does it compare with a scoobie ?
I havnt driven either 
feels a bit faster to 60 than the scooby no competition in wet
Just what I've observed but a typical 2L Zetec on the rollers I use will show 150-160BHP flywheel with carbs or throttle bodies, no internal
mods.
A good method for working back from flywheel figures is to subtract 10 BHP and then take 10% off for FWD or 12% for RWD. More simple allow about 17%
for loses. Thats been a good method on loads of cars I've seen over the years.

175 is pretty good from a zetec with standard head and cam.
156 bhp is 20 more than standard . carbs could give 10 bhp. cams 10 -12 bhp.omex ecu and no cat 10 bhp . thats 30-32bhp that would give 166 -168 bhp
at fly -17%=139bhp where has my 9bhp gone??????????
Mine has 208 bhp & 172 ft/lbs on throttle bodies, Emerald ecu, uprated cams & some head work but standard valve sizes.
Figures on Emerald rolling road.
