My 03 lightning my mods are 6# pulley diablo delta sport chip cold air modified exhaust single blade throttle body etc.
i was thinking about going to 8# pulley my top pulley is stock how much difference on 8# pulley vereses 6# power wise and would i be safe running 8# i need your input on this would my power gains be worth it my chip is already programed for 8# this lightning is driven dailey thanks for all your replys TOM

 

8 is really overspinning if you ask me, you could get away with it but there are no promises. i have a 6 on my daily driver and im perfectly happy. i think you should probably look in other places for power.

 

stock block?

If so stick where your at

If built, throw a 10 lb lower on there

 

I just went from 6#s to 8#s. What I noticed was more bottom end, it pulls much better. Mine isnt a daily driver though, but as long as youre not into the boost all the time I think you would be ok.

 

That'd be me sir!

Six Lightnings I know here in South Florida run the 6# and 2# combo for over a year, no problems. But if it were me Id run just the 6# to be safe.

 

I'm moving up from a #4 to a #6...can't wait, should be here with the new intercooler tomorrow

 

New intercooler? Do you mean new heat exchanger? Bigger resevoir? What?

-Mike

 

heat exchanger, sorry

 

Somebody has to do it .... <grin>


TWO POUNDS !!!!

 

How long have you been running your 6#? I have really been thinking of going with the 4# but I know just as sure as I put it on I'll wish I would have went with a 6#. Have you noticed any detonation? Sorry for all of the questions but I'm just itching to throw one on and mine is a daily driver as well. Hell it's the only transportation I have. I have the FTVB and PSP FastAir so I think I'm ready for the pulley. Just a little nervous.

Thanks,
Todd

 

no detonation what so ever so want some more horsepower it runs strong with 6#

 

I run mine daily with a 6lber, and it runs great! I just put it on the dyno the other day and put down 400hp and 507 lbs of torque. Needless to say I'm very happy!
