well im planning on doing this in the near future and was wondering that since my truck on flat ground runs around 35ishlbs of boost will the htt upgrade give me over 45lbs of boost?

 

You need more fuel for more boost. Just doing the turbo doesnt add boost, unless you put a smaller exhaust housing on it.

 

Have you considered the GDS 60mm Upgrade? From what I understand its about the same thing for about half the price. I really didn't see any gain in boost after this install but it sounds much cooler. EGT's are a bit cooler too.

 

The GDS kit is alot cheaper. and its the same thing basicly.

I don't even think HTT makes the 60mm kit anymore, just go GDS. > click http://www.gillettdiesel.com/H1upgra...wheel60mm.aspx

And its really not outta stock, you gotta call them.

35lbs. of boost is perfect. anymore than that and your blowing hot air. the 60mm kit will probably lower boost a little bit and it will run cooler egt's. and it'll sound awesome and it won't ever bark because of the map slot in the comp. housing. barking the turbo is bad

 

i wouldn't say it wont ever bark or surge, but it will keep those two things from happening alot better than the stock turbo.

and i was told by steve at gds that the 60mm wheel is still in its map @40psi

 

im not trying to get more boost just get a cooler egt without breaking the bank and i asked about more boost cause i dont want to strech head studs.

 

yea yea i gotcha.

The 60mm GDS kit and your 16cm housing will make a good combo.

the GDS 60mm kit whistles AWESOME too

 

ok well i hear alot of guys say that you need to balance the turbo and some say you dont have to can you shead some light cause im in the dark here

 

You don't have to worry about it.

99% of the guys that runt he 60mm kits didn't get their turbos balanced and its fine.

 

well thats good to hear

 

I bought the stealth upgrade, mine is does not make any noise.

 

The HTT stage 4 is a little better than the GDS. It has the 6 blade 60mm wheel. It also requires the backing plate for the compressor side to be machined. Basically the O.D. of the wheel is a little bigger.

The HTT stage 3 and the GDS 60mm are the same thing.

I recently changed from an 8 blade 60mm H1C to the 6 blade HX40, and I think the whistle is about the same. The main thing is the 6 blade is supposed to be more efficient, so you could run more boost.

My hybrid would still surge very slighty and would bark. I had the 12cm though, and too much bottom end fueling.

 

Speaking as someone with an HTT stage IV, I would not do it again. It's not that much better than the Stage III/GDS 60. The extra money would have been better used towards a bigger turbo instead of a barely better hybrid. I do think the Stage III/GDS 60 setup is a great upgrade in terms of bang for the buck.

 

Mines even stealthier yet. In a pile of parts in the corner looking for some phat shaft.



Here phat shaft phat shaft where are you ? come out from where ever you are

 

Jim.... I and the PADTR guys were talking about this last week at our meet and we all think its because your cab is so insulated and sound deadened. The turbo does not put out enugh db to peirce your fortress of dynamat
