Hey Guys,





For the price does it really help out much?And if so..whats she do?

With twice the diaphragm area and spring pressure of the stock wastegate, Banks BigHead keeps the valve seated longer. BigHead produces massive torque right from idle, achieves a higher peak boost, sooner, and maintains more boost throughout the powerband by eliminating premature wastegate blow-open. I think that just about says it....

Make sure you add at least a boost guage and if you can a pyrometer if you're gonna do that upgrade. I have the Big Head on mine, but I got it with the Stinger Kit. Hardly ever downshifts out of 5th when towing, but I haven't had it in the Rockies yet....http://www.dieselplace.com/forum/smileys/HiHi.gif

I have stock wastegate so I can't say if the Banks is worth the $, but I can blow the tires away on low in without it.


However, having the boost come in quicker on my Turbo Buick was always a good thing on the street. (If one raced on the street http://www.dieselplace.com/forum/smileys/Ermm.gif Whether the Banks will do that for our trucks is the question.


I would need to see a time slip improvement personally. Edited by: gmccall

If at WOT you throw alot of black smoke, then a wastegate actuator is a good investment. Just make sure you have a boost guage that can read high enough, because there is more adjustability than you will want to use.

If you get one, read this post I wrote concerning the final boost output. Your mileage may vary, but this is a close estimate.

It is a pin to have to climb back onto the engine to redo it. But make sure you have a good boost gauge that goes to at least 40!

hey guys anyone know what the boost is with the factory waste gate? my banks says to turn in 7 turns from factory and my boost only went to 14 or 16. i dont remember how many more turns i went in but 4 seems to pop into my head, any way my boost went up to 20 so i turned it in 2 more turns today and with truck empty it hit 24 - 25 in 3 or 4 gear. i will be towing our fifthwheel the 21st and will know what it goes upto under a load.
