Just recently purchased an '01 lightning and am anxious to upgrade it and make it faster than it already is. The only thing that has been done to it is that the manifolds have been replaced with "shorty headers". Does anyone have any suggestions of what I can do to upgrade the performance of this truck. Keep in mind that I know very little about cars...but I am hoping to get some quality opinions. Thanks!

Considering they are supercharged then I would think more boost.

Changing the super charger pulley would achieve this but I don't know how far you can go.

Hopefully someone can give you some more details.

Yeah i have heard that changing the pulleys does something to add boost. Alot of people were saying that the smaller the pulleys that you use...the more boost you could get. I wish someone could direct me exactly what to buy and install because i know next to nothing about cars. Although...I am looking forward to learning something. Thanks for the reply

Yes what you have heard is right and it will be the best way to achieve alot more power quickly but we need to get you on the right track for the sizes and the amount of extra boost the SVT can take safely.

Hmmm I might know someone that can help.

few things i would recomend.

Go get your sc'er ported. http://www.stiegemeier.com/index1.html

Depending on what sort of power you want depends on what you should do ..

You can go with a 2# upper pulley and a 4# crank pulley.

You will need to get it tuned once you change out the pulley's I would recommend SCT myself. Not because they are an advertiser here, but they are one of the best.

Hey lunatic, thanks for the idea. Can you explain to me exactly what it is that they do and how this affects my truck? Apparently I send them my super charger. Say i get a "stage 3" done which seems to be a reasonable price. What exactly are they doing. They are talking alot about "blowers" ...what exactly does all this mean? Let me know...Thanks again for the help!

i have a 02 lightning.
iam running a 4lb lower and a 2lb upper and cai.
stock these trucks make 8lb of boost.
iam making 14lb of boost.

the chip or programer you use is you choise .
the vendor is your choise
put i do recommend sct,the other seem to have a problem.

what they due is adjust timing for the boost increase and adjust the a/f ratio,
trans line pressure can be adjusted.

when you increase the boost you will have to drop a heat range in plugs.

when they put the headers on the truck they hurt the performance
because of backpressure.
if you get a mail order tune go with jdm they are behind some of the fastest
lightnings out there and from going to the dyno with my truck and 3 others
they were close.

porting the blower is a great idea and very cost effective.
but changing to a magnum powers case with the internals of your blower
is cheap also.
the little eaton makes to much heat past certain levels of boost
making it ineffective.
porting the blower helps by inproving the air flow and reducing the temps
inside the blower.
also a bigger intercooler will help.
i think jhonny lightning performance makes a good one.
there are all kinds of mods for these trucks.

the 4.6 the 5.4 have a problem with blowing plugs out of the heads on
pre 2003 cars and trucks.make sure your plugs are tight.
