the sliver 62 was a killer turbo i ran one for a few months before i steped up the the bullet and you wont need studs i run the bullet with no studs and dont plan on studding untill the twins get her in a month or so. but that 62 i ran was bad it spooled as soon as you touched the long skinny pedal.

all in favor ........I agree except the 62/71/13ss IMO better then the 65 wheel for your application if you towed more and heavier then the 65 wheel is better.

Ghost Ram,
I am in the process of changing my stock turbo to the II Silver62. I am hoping to be driving it later this week with the new Tranny/Turbo. I will be running stock injectors and Smarty. I will provide my thoughts after having real world comparison.

Our trucks should be fairly similar in mods. I am not sure how different 4.5 injectors are compared to the 06 ones.

I am excited to see what the difference will be like for my daily driving.

PDI hooked me up with a II Silver 62/80 and it is a quick,hard pulling bad *****. Luv it!!

This has been my experience with the Silver 62 also. No lag at all even with stock injectors.

nrussell how do you like doug and jarred over at PDI they are a good group of guys got all my work done there you will love the silver 62

Ghost Ram

that would be great, im very interested to hear the results myself.

after speaking w/ anthony at htt earlier today i am even more confused as he recomended their 64 w/ the 65 wheel.

he told me i wouldnt notice any difference in spool up between the 62 and 64.

i dont know if i can take his word for that?

the best thing is call Industial injection and ask them they will tell you what works the best and what you should run.

82snpr they are very helpful and have excellent customer service. I told Jarred what my truck has and what my future plans were and all he said was "I got you covered, you will be very happy with what I am going to order for you". They are in utah? (right?) anyways I live around Atlanta and in four days my turbo was at the door.For a west coast deivery to the east coast in four days was pretty impressive. Turbo was installed the next day and I can't wipe the grin off my face for nothing. My wife says it is to fast, but the kids smile just like me.

65 super quick to spool
71 quick to spool
74 not as quick to spool

bigger wheel is slower to spool

O.T

hey where's the report you promised on your huffers

All of those turbos are slow to spool compared to your stock turbo with about 60 mm turbine, and 9cm exhaust housing. If you want more power but characteristics like your stock turbo, the 62/65/12 or 13ss are the way to go. If you want to shift power up a tad in the rpm's and have 50 more peak HP, get the 62/71/14 or 13ss. And if you want to shift power up even farther in the RPM's almost out of your common usage range, go with the 62/74/14 II. The silver 62 will run a lot higher egt's than a HTT 62/71/13. The Silver would start to run cooler than the HTT once you hit 1450* or so at well over street driven speeds.

My final thoughts, if spool up matters, steer clear of big exhaust turbine wheels. If peak dyno numbers matter to you, get a big ol nasty turbined turbo. A 62/71/13 will be hands down more fun on the street.

Good advice from BB24, imo^^

I would say get the 64mm. but I like to go a little bigger than needed. if you arent gonna be hooked to a trailer everyday a 66 would work pretty good also. Jdearden has posted before he pulls his horse trailer and i think he has a boat also that he pulls alot with his truck and its a sps66 I believe

from my past experience I have learned its always better to error on the smaller side with a turbo for the street = drive everyday smile everyday

for dyno & drag strip use in most all cases bigger is better !
