What would a twin combo like this produce for HP. Would it require nitrous to work well? I would like to use my HTT as the small twin and I really don't want to run nitrous.

I think you could make it work without N2O. What exhaust housing do you have on the 66?

I really want to try the GT47 as a single.:)

:eek: your getting twins.... sweeeet :D as for my thought i think your 66 would lite a 47 fine with a little tuning

P.S did you buy an HPT yet??

Someday I will do twins. Need to build the motor first but I would like to get things figured out.

x2 get one of the smaller housing for the 4718 and put a wastegate on it..

things to remeber... the small turbo is off line and mid range then the big tubo kicks in to finish out the top end.

That should work well. I was hoping you did not have the small iron one it will choke things out when the GT47 comes on

I was not refering to the GT47. A 1.23 should work fine.

But it is an old school wheel, not ETT. I am not sold on ETT yet even if it was. The GT4718 is a fire breathing monster. Very few turbos can with it. The BW 488 can not IMHO.

I could see that effecting it in a single setup but shouldnt be a big difference compounded. Ive seen the ETT wheel listed for a 488 before, more money than the conventional one.

i cant say wich is better but i think any of the below would be a great choice dependant on money and hp desired i would discuss with who is doing your twins wich would work best with your HTT , i know the s480 , s490 , or 4718 will .

S480 80.31 inducer 98mm turbine T-6 1.31 A/R $1000-$1300
S490 91mm inducer 100mm turbine T-6 1.45 A/R price prob $1300-$1500
4718 88mm inducer 92.7mm turbine 1.39 a/r $2000-$3000 dep bearing stye
gt55 91.2mm inducer 111.4mm turbine $3000
