Gentlemen,

I have run a search looking for stock boost levels on the L, however I can't find enough postings to get an average number. Can you please post what your stock #'s were so that I can get an average? Thanks.

 

outnumbered
According to my '00 brochure it's 8.0 psi...according to my POS gage it's pegged with or without my pulley.....JR

 

Well if the manual says 8, then I guess that''s the number I should go by. Thanks

 

My stock gauge shows 10 Lbs on a cool night. Seems to be 1 or 2 less on a hot & humid day.
Make sure your bypass valve is properly adjusted, otherwise some of the boost may bleed off.

 

I think im at about 14

 

I have never seen a stock Lightning, of any year (second gen), create less than 9Lbs of boost.

 

the first time i got on it the needle went all the way to the top of the guage(10psi)

 

10

Blown 93 Lightning
1.83
13.2
103.00

True Blue 2002
Stock
2.0
13.44
102.00

 

stock 10lbs now i see on the autometer boost gauge with my mods i see 16.5lbs-17.5lbs on cool cool nights

 

This is going to sound extremely stupid and i apologize, But what is boost, apparently i know what youre talking about. but then again in a certain way i dont. hard to explain what i mean.

 

Reed, the "blower"/supercharger on top of the motor pressurizes the intake manifold and forces air (forced induction) into the motor. That forces more oxygen into the cylinder. More oxygen/fuel = stronger combustion = more hp. It's common to refer to the pressurization of the air as "boost", i.e. turbo boost, boost gauge, etc.

Straight up 10 stock...A little higher after JDM stage one.

 

It averages about 8 psi- a little more in colder/low altitude climates, a little less in hotter/high altitude areas. Although with just the upgraded intercooler and a panel K&N I regularly hit 10+ psi in the hot Phoenix AZ climate.

Mine pegged 10 stock.
