rolling road

hi ppl

took my car for a rr session today
158.1bhp@flywheel
128.7bhp@wheel
max torque 168.9lb ft

is that good or bad for an atmo?

that is exactly the same as i got for my old atmo a few months ago!

guess thats fine as they are 160bhp from new, and are now 20ish years old.

I'd have thought yours would push out a bit more Rob with your big carbs. Your RR figures though show only a 30HP loss in the transmission so that's probably a bit conservative.

If they got that wrong (a lot of people see 50HP loss) then that'd make it 180HP at the flywheel which would be pretty good!!

hi ppl

i thought it should be pushing a little more aswell
ambient temp was 33 degrees c
that wouldnt have helped much

suit case open or closed?

hi all

suitcase was removed maybe that was the problem???

[stephendell]

No, you must have the suitcase

Just remove the suit first. Else it'll get jammed in the carbs.

It is interesting that the Subaru Impreza loses 70bhp in the, not very efficient, transmission. My 250bhp one only gave 179bhp at the wheels. The Alpine loses much, much less.

Not true! Clee saw 60bhp transmission loss on his car....which isnt much less than 70......10 to be precise

Oui
Now has a freed-off caliper and brand new hub bearings so will take it up the road and see if any improvement

Perfect, same as I had on a standard atmo, but then I fitted a high output pump and adjustable fuel regulator, and played with the dizzy timing, and brought it up to 174bhp at 5800 and made more torque at 3500..

Did go and feel much faster...but did use more fuel..

A 21 T Quadra loses so Im informed about 50 BHP in transmission losses, this i beleived to be high, with an old design 4wd set up......I was led to beleive that the new japanese technology had much improved these losses? obviously not can anyone please inform me further?

Si21

from what ive been told is a pulsar gtir only makes around 160-170bhp at the wheels so they are very simialar
