pulley mod kicks ***...the low and midrange power increase is very obvious...your redline will drop about 400 rpm though...

 

p.s. boost pressure guage with nitrous reads 20 lbs...is that intimidating or what?

 

Hey There I Had My 99 Lightning For About 1 Year And Think Its Ready For Some Mods Im Thinking Of Puttiing A Single Blade Throttle Body, Inatake... My Main Concern Is With Putting A 2.73mm Sc Pulley Adding 3lbs And 8.00'' Diameter Crank Pulley Adding Another 3lbs And Then Putting It On The Dyno... My Questions Is It To Much To Change Both Pulleys Or Just Go With 1 So I Wont Force The Sc To Much????? Or Just Go With The Crank Pulley 8.50'' That Adds 4lbs???

 

you can ad a 4lb pulley to your truck and it will put a huge smile on your face,,,start there

you might need to change to a cooler spark plug

 

Dear god, how old is this thread????

 

Wow, good use of the search tool.

 

Pretty interesting to see how reluctant they were back in 99 to add just 3# additional boost...and "overspin" the Eaton!!
