I got the htt 62-71-13ss was wondering if anybody has any input which ar size would be best in a twin setup? And no I dont want a s480 it would be overkill for the fueling I am going to be running. How much boost is these htt ss housing turbos good for, I dont want to kill it before my twin install. thanks dave.
 
i bet the 62/71/13 and s475 will spool a little bit faster than the silver bullet, prolly would have been better off w/ a 62/65

i have an s300g (57/65/14) and plan to eventually put an s400sx under it, should be fast spooling and good for 650hp
 
i do have to run my secondary as a single till i can afford the rest of the set that is kinda why i went that route. I can make 52 psi with bullet and it spools hard from like 10 all the way there but getting the first 10 psi is what is bugging me. I was thinking that the 62 would put me in a different boost range in all around driving which is what I need. But the top end of that bullet is like a new piece of ass i am all smiles.
 
That setup spools very nicely. I would say faster than a silverbullet.

:hehe:
once you get the 475 on, you'll be saying silver-who? the top end is way beyond the bullets capacity. the twins will be mellower spooling than a single but pull earlier and further.

You can say that again.

i was playing around yesterday and it pulls so hard on the top 100+. I was scared something was gonna break. Its like the engine wants to keep pulling but the truck is holding it back, like their fighting each other.
 
I've said many time...mine pulls a hard over 100 mph as it does at 40 mph.
Once that big charger is lit....it's a whole lotta fun. BTW...mine is a 1.32a/r S475 also

Im only seeing a lil over 20psi with 50-55psi total, i cant imagine 26 or 28psi from it. Ill be glad when i finally get my WG dialed in.
 
I see 62-63 total with 25-26 from the primary.
No gates on mine...secondary is a 64/71/14.

I'm hoping to get a bit more from the primary when I get my CP3 back with some Floor It magic done to it. I'm running out of fuel on the top end bad....it barely hits 1250 on the pyro on a 0-120 mph run. Several thousand more PSI of rail pressure should take care of some of that....if it doesn't then I see some bigger injectors in my future.

i think ive seen a spike to 65psi before but not yesterday, i was rolling into it instead punching it to the floor. Thats about the highest ive seen egts too, 12xx, maybe 1300.
 
wait 'til you guys get some more fuel in there! it just KEEPS PULLING! just will come on earlier and harder, hahaha!
 
how big is your guys fueling i.e. injectors, pums, etc. dave(tirefrier) is running 90-100hp II injectors with a stage 3 dragonslayer cp3 going in soon. is this enough to see the most out of the 62/71/13ss over a s475 1.32?
 
I'm building that same set! 62/71/13 over 75/96/1.32, I can't wait! My hx35/40 over ht3b were fun, I imagine these will be that much better!

That will be a very nice set-up. Very similar to mine and I love mine.
 
I'm running 250+hp stix and Quad ADR with SOvp. I had the 40/3b set up and yes, the 62/75 IS that much better!

would you recommend the 1.32ar as well? 700 hp is as far as I want to go.
