At how much boost is it needed to upgrade to better injectors and 225 fuel pumps? Im running a 8# lower and my L runs great.

 

Bigger injectors are needed if you want to go over 500 rwhp....

 

s.cal L 2,

I talked to the Bosh rep for my plant and he said that as per my dyno sheet and the data I gave him my injectors were at 98% of there duty cycle at 467 hp and 566 ft. of torque. Thats with 16 lbs of boost and Port and polished every thing

What would happen if it runs out of injector? It doesnt ping at WOT, it pulls pretty good.

 

It pulls good prolly because its lean...a lot of times you cannot hear detonation. Be carefull.

 

Thats very true! I know what detonation sounds like but still just fried 3 pistons and melted 3 lobs on my heads due to detonation. I first noticed a while back when I found 2 spark plugs with out electrodes!
When mine was on the dyno it sputtered on the dyno thats how we found out about the injectores being maxed out.

I hear that. When my spark plugs were changed we found aluminium on #3 and #7 and the others looked slightly dusted...time to run a little richer (slower )
