ok so i made my own pvc intake a while ago, i havent been driving the truck since but today i drove it about 250 miles and it seems to have more top end but not a whole lotta bottom end like b4? i switched from a 2.5" aluminum egay intake to a 4" pvc with a AEM dryflow filter.. any insight? would a smaller intake yeild better velocity for low rpm torque?

 

no takes?

 

I'll bite, there is a guy on dodge talk who slapped one of the ebay specials w/ the pencil dick tube on his truck and he said it felt like it was actually hurting performance. I haven't tried both so I'm just speculating here, but even that stock accordion tube is bigger than 2.5" and the mopar/AEM is 3.5" and that is dyno proven for gains. I don't know if 4 inches is too big or what, but I have the spectre which is a mopar clone on my 3.7 ram and I noticed a similar bump in the powerband up to the higher rpms w/ it vs. the stock setup. I think you'll get used to it and find that you like the way it pulls w/ the pvc better than the ebay one.

 

yeah, i might clean out the filter, and my tranny is due for a service might help out with the slugishness at the bottom end, and i think a tunner would make it run a helluva lot better, might settle for a power wire and see what happens , i was just wondering if any1 els had any experience with a 4" intake and the bottom end loss

 

Don't buy a power wire...put a resistor (4.7k I think..there's a write up somewhere) inline with the IAT and it's the same thing.

For the intake i'm not sure why the powerband would have shifted from just a CAI....did you do any exhaust mods at the same time?

 

nope i just got a FM40 single in dual 2.5 out but thats been on there like 2 weeks after i bought it used to be able to burn em all the way threw an intersection with out even braking a sweat, now it barely chirps em, but has ALOT of pull after like 3800, i like and would rather have the low end grunt, help alot more with them there MPG's lol
