Hi guy's,
I would be grateful if some one could let me know the specs on my car including compression ratio.
I've read some bits on upping the horsepower on lpt cars, but am not sure i have got all the info. So far all i've done is add a intercooler, how much work is it to add a bleed valve and I only want to run about 185 to 195 Hp. Will i have to adjust timing or anything else, or is it straight forward?

Welcome to Saabscene

What sort of car is it?

What engine does your Saab have? The LPT 2.3L used in the 9000 had the same compression ratio that the B234R did in '97: 9.25:1. Basically, all the B234 turbo engines were the same - they only differed in software, except the B234R, which had the MHI turbo. Don't worry about the timing - that's all done with software. Anyway, it's hard to say, exactly, what you need to safely add horsepower until you say what engine management system you have.

It's a 900 se LPT 1993 L-reg 3dr hatch. Lucas on the airflow meter, 2.0 ltr

Welcome to SaabScene

I'd have a look at these two threads running in the C900 forum: Adding APC to an LPT and Adjusting Overboost Protection . They should help answer your questions (and possibly raise a few more).

The compression ratio for the LPT was 9.0:1, the same as the FPT 16 valvers.

Thanks for coming back on this guy's and for the welcome.
