:D anytime dude anytime :D  any other questions  just ask  :cheers:  :drink:

so have you takin it for a blast ? be carefull you don't know how meny pounds of boost it  will make..

if it starts to clime over 7-9 psi get off the gas!! it will go BOOM!! with pump gas and no boost retard.. unless you have like 7.5to1 comp  :giggle:

so if it makes over 6psi we will have to do some more talking ;)

i havent had it for a blast yet, im doing that tommorrow.. I dont even have a boost gage setup , i was told ill be lucky to make 7 psi with that on my car so i didnt think i would even need one.. and my comp is 8.5 to1... so i guess we're going to talk some more, lol..

dude your safer with the 8.5to1 but don't go stabing the throttle with out a boost gauge you never know what it's going to make for boost

i know that blower can make in the upwards of 15-17 psi on a 3.8 and yes it should only make about 7 psi on a 5.0 but you never know it might make 10 psi depending on the pulley setup..

so get a gauge or at least if you have an old cheap oil pressure gauge lieing around use that to see what boost it's making because if it makes 10 psi it could go BOOM! if it's to lean and/or if your useing low octane fuel. ie lower then 100 octane with out a boost retard..

Im making 10 psi but im running really lean .. what now blown306 ? boost retard ?

Re: Need Help Guys....

see so you do make 10 psi ;)

ok how do you know that your running lean? explain..

yes i would use a boost retard.. but the only right way to do this is to use the msd with a boost retard or instead of buying a 6AL and a boost retard buy the 6BTM .. it's a msd 6Al and boost retard in one..

then you can set your timming @ about 12-14 degrees BTDC and set the retard at 1to 1.5 and it will take 1to1.5 degree's of timming out per 1 pound of boost..


but you need to know for sure that you are running lean with a blower you should be runnning at about 11.5to1 "air fuel ratio".. lower..meaning like 10.5to1 would be rich and higher.. meaning 12.5to1 would be lean..

if it is running lean then you will have to rejet the carb..

let me know..

and when you advance the cam opens the valve sooner before top dead center

now if the igntion fires @14 degrees BTDC it's firing 14 degrees before the piston hits TDC right and so then the timming is retarded
And that's where everything gets backwards.
 
You're saying the sooner a valve "does it's thing" before TDC, the more advanced it is, but the sooner a spark "does it's thing" before TDC, the more retarded it is?  :grinno:

The general terms used in timing are advance, retard, initial timing and timing curve. To advance timing is to fire the spark plug sooner or more degrees before top dead center (BTDC). To retard timing is to fire fewer degrees BTDC (for example, moving from 12 degrees BTDC to six degrees BTDC).

And yes, I DO always have to be right.  :tg:

all of you guys have your timing degrees wrong.  If you are 8 degrees advanced it means that spark is occuring 8 degrees before TDC.  advanced=earlier spark before TDC.  retarded=later spark after TDC.  TDC= 0 degrees
