Two large turbos with a supercharger would be sick! :drool2: to be practical though I would go with either the he351cw or the 63/68/14 over a s475. I wouldn't do the 480 unless you really want that top end power because it takes a noticeable difference in time to spool up.Find Crazy Carl. Turbolvr on here. He's the triple master. Or twins, or twins with a supercharger!!

Haha Thanks :thumbsup:Nice user name, I should have thought of that...
Anywho I'd do the 351cw over 475. Port out the wastegate on the 351 and if you have the coin get the 75/92/1.10. Fast spool with plenty of low end power and enough air for 700.
I have read about many of his builds on here. That is actually where I got the triple he351cw idea from. Hopefully he will chime in with his inputFind Crazy Carl. Turbolvr on here. He's the triple master. Or twins, or twins with a supercharger!!

A compound set up would be sweet with a supercharger. Wish I took the blower off my camaro b4 I sold it. Looks a little complex and expensive to do unfortunately so ill probably stick with the turbo configuration.

Thanks for the input. So far its looking like the ported 351 over a 75/1.10 is something everyone agrees on.When in compound arrangement is there a pretty big difference between the 62/65 and 351?A 351 or a 62/65/12 over a 75/1.10 would be the best bet. The 351 would spool a touch quicker, but the 62 would have more top end. Both are good choices though.
Did you ever run that 62/65 over the tighter 75 with the 1.10 housing? How did the 63/68 seem to spool compared to the 62/65?i had a 62/65/12 over 475 with 1.32 housing, i switched to a 63/68/14 over a e.d. 475 1.10 housing and i like it wayyy better, the 1.10 housing spools faster than the 1.32.
dimensionally yes. the 351 is shorter in most ways..When in compound arrangement is there a pretty big difference between the 62/65 and 351?
There's a pretty decent difference in the time it spools between an HE351cw and the 62/65. The HE351cw spools quicker mainly due to the turbine wheel being significantly smaller and lighter; the 351 has a 60mm turbine wheel with a tight 9cm housing undivided that is about equal to a 11-12 cm divided housing.Thanks for the input.

What set up do you think is best for my goals? I was thinking it would be cool to do a triple turbo set up since personally I've never seen a triple turbo-ed first gen before and like to be kinda different. Unless there isn't much benefit from doing it over a regular compound set up?dimensionally yes. the 351 is shorter in most ways.
The 351 will also spool faster.
Yeah the gt55r is a bit too spendy for this guy at least for now. Is there anything better than the 351 to run with the 475? Other than porting the waste gate on the 351 is there anything else you would do? How much power has a set up like that made or do you think it can make efficiently? of course with everything else properly set up.trips are great if you want to spend the time fabricating. better than twins @ 700hp? not really. there isnt much difference to speak of except the range of turbos that can be used.
either can cost a fortune or be fairly cheap. either can spool just as quickly.
Trips are more for high 3 to 4 digit power where the mass of a large primary may prohibit spool-up or space issues restrict its use. the GT55R is tough to beat as a big single primary, but not cheap for sure.
the 351/475, 1.10 T6 would do well.
Lately I've been seeing more guys putting an HX40 turbine wheel in the HE351. I haven't heard much about the results, but I would think it would have better exhaust flow (especially with the ported gate) and still spool nice.I think I may have it narrowed down to one of the two following unless anyone has better suggestions
62/65/12 over s475/1.10
he351cw(ported) over s475/1.10
looking for quick spool and efficient 700hp that can tow/race/pull/get groceries
Should I do any external gating or billet compressor wheels or race covers on any of the turbos in either set up?
