For me, the sound wasn't all that great with the stock intake tubing and airbox. Today I replaced that with the ASA modified intake and the turbo is much louder now. It makes it presence know at 5 psi, and absoulutely screams at 25 psi.

 

well i stopped using the stock airbox a long time ago haha

 

sound even better at 35+ psi

 

Based on the comparison between these two, it seems like the 60mm upgrade is the way to go. Plus, the extra whistle would be a big plus.

However, is there really enough difference between the 60mm upgrade and the HX35 (2002 model, not sure what size wheel that is) to make it worth the swap versus just the leaving the HX35 on there as is? I guess I'm just trying to get that "extra push" that will convince me to get the 60mm upgrade.

Thanks again guys,

Dawson

 

hx35 wheel is 54mm as far as I know

 

Wheel size isn't all I would worry about. You have to remember that the H1C is almost 20 yrs old, and turbo technology just keeps getting better. I would factor that in to my decision.

 

Does the 60mm require more fuel for it to run efficiently? My fuel screw is in about 1.5 turns if that helps. Also, this will help lower EGT's since the larger wheel will push more air, right?

Thanks,

Dawson

 

It'll run fine with stock fuel. I'd expect to see lower EGT, probably around 100 degrees at full power.

 

Thanks Dave, now I will just have to decide what to do. I think I will probably go with the 60mm upgrade, and I think my dad will want one for his truck too. Thanks to everyone for all the input.
