Why?

[DuFFMaNn]

So I have a friend who owns a 2001 Lightning with something weird happening. The truck is Bone stock (that he knows of, 2nd owner) yet is some how pushing over 10lbs of boost, and is dead even with a lightning with slicks, intake, pulley, and tune. We have measure the pullies and they are all stock length.

Does anyone have ANY idea why he would be pushing so much boost and keeping up with a higher modified Lightning?

maybe the tune on the modded L is crap. :shrug:
maybe the 01 is a factory freak. :shrug:

Ported blower?

Ported blower?

That would make sence since you cant see it. Tell your friend to have it put on a dyno and see what it puts down. Then you will have a better idea of whats up.

i get over 10 lbs on the factory gauge too. they are'nt very acurate. i have beat guys with full exhaust, pully, cai, their truck sounded like shit cause the tune was way off. and ya some of these trucks are factory freaks. mine put down 380hp/451trq with just a cai, tuner, and two flowmasters on it.

+1 on the ported heaton or the other truck having a super conservative or crappy tune.

Did you just measure the upper pulley or did you also check the lower pulley as well? sorry have to ask.....

The modded L has a shitty tune. :idea:

That's just a myth propigated by arm chair engineers.

something about great minds, right Bob??:beer:

 

[PhLoBuS]

intake and pulley would give you more than 8lbs of boost...

 

[DuFFMaNn]

Both were measured, and I am pretty sure he got a good tune, but I guess its a possibility.

Also wouldn't a ported blower not do anything without a new pulley.
