I'm going to order an 03 Lightning at the first of the year. How much boost can these motors SAFELY handle with a good tune? I have a 96 Cobra with a Vortech S-trim that I'm only running 8#'s because I want to be somewhat safe. With the somewhat built motor of the Lightning could I easily run 12#'s? Or will I need a built lower end first?


Thanks,
Pete

 

You can run as much as you want.... As long as its tuned for it.

 

seems like a extra 6 lb's is the norm for street use these days

 

6#'s! WAHOOOOOO! 6#'s and 63 degree weather in South Florida is quite a combo!

5 lb pulley=5+ lbs for 39,200 miles.....no problems.

You should see what happens with a 6 and 39 degrees

 

I hate you Jersey boys! Shiney trucks, sweet mod's, bling bling, and cold weather! Not cool!

Going with a #4 myself with a very safe tuned chip.. I don't need problems... Many run 6's with no problem... hope this helps........

PEACE...............

 

Iculokin basically is correct.Its all in the tuning. The engine can handle 16-18 lbs total safely with proper tuning . The supercharger I believe can spin up around 17,672 rpm's. This is at an engine speed of 5,400 rpms, all with a 6 Lb lower and a 2.75 inch upper(2 lbs) This is pretty much what the "experts" say is above the maximum rpm recommended by Eaton.I know several lightning running this combo with no ill effects...and they all run like a raped ape! Its all in the proper fuel and timing tuning of the chip.

 

i'd recommend a 4# or 6# for a daily driver....

 

Bah...they only roll like that in the summer....ask most of them where their trucks are at in Mid-Dec thru March

When you can still roll with your windows down in the Florida sun they are freezing their a$$es off and driving their Escort Wagons


Gotta love Florida

I would rather get good air some of the time then bad air all the time.

 

I don't drive an Escort wagon

 

Yeah, she might be put up during the week...but every weekend as long as thier is no snow on the roads or raining...she is out terrorizing the town! Coldest she has been on the road is around 10 degree's last winter. And boy does she like the oxygen rich air! LOL.

 

Or a 5lber and Nitrous in 20 degree weather!!!!!!!!!
