How would a HTT 64/14 work over a S475.I'm running the 64 as a single now and I bought the S475 on EBAY at a real good price.Thanks

It will work, but will be somewhat laggy... I'm thinking a little slow to about 12-15 psi then will lite after that. But yes, it will work.

depends on whether or not you have the 65 or 71 in your 64/?/14 ?

? injectors & programming you have ?

is the S475 wastegated ?

depends on your intended use of the truck that the turbos will go on & expectations as far as spooling , towing , racing, etc .

IMO the 62/65/14 - S475 would be excellent choice and a better setup for towing & everyday driver

if your after big power the the 71 would help with keeping drive pressure down with more aggressive fueling

the 64 is really better suited and serves a much better match-up with the bigger S480 application

your 64/?/14 S475 should still work though !

we need more info from you to help with suggestions / advice / set up , etc

I was assuming 71 compressor/exducer... I have only heard of a couple of folks with a 65 mated to a 64 inducer...

Actually that is what HTT is recommending to most people. That is what my dad has - however, he wishes he would have gone with the 71.

88 in a top charger ?

don't you mean 88 in the primary charger ?

The truck is a daily driver, no heavy towing, weekend puller and drag racer. The htt is a 64/65/14, the s475 is not wastegated, 120 ddp tips, programing is Smarty tnt/r beta.

yea zoo you mean the primary right hehehehehe

I would recommend upgrading the HTT 64 to a 64/71/13
and also upgrade your S475 to a wastegated S480

throw a quality pressure box in the mix mp8 and you be good +800 rwhp

then just hope your trans will last & hold all the power !

I am running a 64/65/13 on top...works great. It is really splitting hairs between a 62/71/13 and a 64/65/13...

One costs less though... ;-)

Is everyones lingo right...the bottom charger should be called the secondary???

Wow, what I started here... First, that 88 compressor (exducer size) wheel is going in the TOP turbo. The Top turbo is correctly referred to as the Secondary or high pressure turbo. The lower turbo is correctly referred to as the Primary or low pressure turbo. My Primary Turbo will be using a 108 compressor (again exducer size).

I am a little backwards today...anyways...why so large?
