Rolling road results

[The_one]

Well today i went to a rolling road at powerstation in Gloucester.

As today is so hot the temps even in the dyno room were high (29 degrees ambient)

Anyway i managed to pull

199bhp @ 4685rpm
235lbs torque @ 4015rpm

I think my power is down because of the high temps? What do people think from my log below which was done during the power run.

Shouldnt it continue pulling a bit more past 4500rpm? I didnt think even the k03 tailed off that early?

[The_one]

Heres my power graph

 

[m0rk]

it's flowing 158g/s when you aborted the log.... so it's not "that" bad

they didn't rev very much though

 

[The_one]

Heres a log from road driving,

Doesn't pull any cf's on the road but as you can see pulled quite a bit on the rollers

[The_one]

What do you mean by they didnt rev very much mate?

 

[acidstrato]

some of those cfs are still quite high...perhaps pulling timing back would be abit better

powerstation fans up to the job?

 

[The_one]

Mate on the road it pulls NO cf's back whatsoever im only runnin timing 4, need to to put the timing up to be honest, im sure its pulling back because it was roasting in the dyno room

 

[m0rk]

look at airflow & rpm

they don't rev it past 6k on the log

however peak airflow looks similar on the road vs rollers

pulled back because of heat & timing I guess, what inlet temps would you expect to see on the road?

 

[Madmile]

As above either to much timing or to much heat.

 

[The_one]

When i've logged on the road i haven't seen above 42 degrees so far.

On the rollers it hit a max of 50

 

[m0rk]

and that was at the start of the run!?

 

[The_one]

yeah the inlet temp was 50 degrees at the start, as soon as run started it went down to about 45 then went back up to 47/48
