Compression ratios are a ratio, 9.1 is not a compression ratio. 9:1 is a compression ratio.

And what he said, kick him in the nuts. Your B20 stock had I think 8.8:1 compression and they do ok.

Mustang svt's are 8.5:1 as far as I know and I reckon the 5L mustangs have even lower compression ratios and they don't have trouble starting up.

Another example would be H22, low compression. Pretty much anything with a large amount of displacement isn't compressed, top-fuel dragsters not included, because that would end in death and doom of the universe.

Considering that the pistons have zero bearing on the car starting, I'd say that boy needs a wee-wee blast.

What exactly was he trying to use as forced induction to start the car? A hair dryer? @ his groin.

edit: Sorry I read the original and thought he was a mechanic or something that was advising you.

Considering a B20B (USDM) has 8.8:1 compression

I think exeptionally high comp requires stronger starters. Diesels are like 19:1 and higher and have different starters than gassers.
