Airflow to BHP formula

[P10 GGOT]

Can anyone please provide me with the formula to work out rough BHP from Airflow.

I know I've seen it some where on the site but after looking for last hour, thought it wold probably be better to ask.

Cheers
Chris

For a LCR MAF reading in g/second x 1.3 seems to be about right

Is that the same for both the 210 and 225 lcr's?

 

[Willie]

Yup

I recorded 152 on my gauge last night but x that by 1.2 and you are at my 180bhp(ish).

Yes, Thats what i used. Version 403 i think, run a log (block 1, 2 & 3) and open results in excel.
Thats what I done

Wouldnt mind giving this a try. so do you have your engine running with the the software to log the results? can you may be detail a few steps for me cos knowing me, i'll probably do something wrong

Plug in, fire up laptop and car. Set logging on the blocks in vagcom then find a long piece of road, select 4th gear and gun it from low revs to redline........
