Should work, I think it will be kind of laggy with the real big exhaust wheel. The 40 in twins will be slow to spool, just guessing but around 1800 to lite.

Having the Hx40 w/14 m housing should spool pretty well. And the exhaust housi g on the Primary ain't all that large. I think with the right size injectors it might be great.

Give Lee at Contagious a call... He's a sponsor here now I believe..... His sticks are all I have run in my trucks... Top notch work. And WAAAAAAAYYYYYY cheaper than the competition.

If you put great big sticks in it will still be kind of laggy but it will be real smokey also. Just my opinion.

it's better to consider the 'entire package' when setting up twins... than slapping some parts on it and hoping for the best

Yah, that's one way to get in the bowl... other way is to have the spray angles tightened up, which I know Lee has done during the EDM process...

I don't see why these turbos want work even if I change the top to a Hx35 with a 12cm it should spool perrty dam good, I mean hell most s475/s480 in twin setups run 1.39a/r I have a 1.23 and my compresser wheel is only like 2.5mm bigger so really don't see the porblem. 5ks,scdv,with 370 I think I should have anof fuel... If it don't light to 2000-2500 hell with it

Try it, its not a terrible setup. Just don't over spin the hx40.

Also you have to remember your turbine is bigger on the primary even though you have a 1.23 housing.

Yeah they don't like a lot of boost. Their known to snap shafts. You should be good, let know how it works out.

Open!!! I think its going to be a lil laggy but nothing that's going to hurt it. It's only a 4600lb truck... It'll be a rocket when she dose lite...

Do a little more research. That 2.5mm is the difference between making her writhe and scream or just wiggle when she goes.
