Anyone here running a different aftermarket intake? Like the vic jr, F.A.S.T, ect...... on a 4.8L or 5.3L?

 

On a 4.8/5.3 I really don't think there is anything to gain by upgrading the intake, many guys gripe about loosing low end power when swapping intakes.

 

i found a thread here.. i don't know if u can see the pictures though

The dyno chart is on page 5, it shows the LSXRT intake does not have any gain (vs the stock intake) until about 3800rpm. On a daily driver....you would feel no gain on the butt dyno unless your like me and 6000rpm is part of your daily driving routine.

 

Sweet, thanks!

 

Yeah its more of a weekend toy now plus we spin it up to 7200rpms (4.8L) we kinda wanna lean towards the Vic Jr since its going to receive a 200 shot
