looking for to4b comp wheel info

[grey98]

I was trying to find info (flow, comp maps, opinions, etc...) on the to4b compressor wheels, specifically the V, Super V, H, and Super H. I've been to both garret's and turbonetics web sites and can find anything. Anybody?

You went to turbonetics site and couldn't find any of those comp maps??? Here's a direct link, I can see how Turbonetics bright colors can throw one off :

yeah, I found those not long after I posted, but not on turbonetics web sites, just by searching on google :dunno: guess I'm just dumb sometimes

But I've spent all evening trying to find super v and super h info with absolutely no luck at all.

looking at other "super" turbo maps vs their regular maps, it would seem it just sort of streches the map upwards a good bit, but doesn't really change the max lbs/min. One site said the super turbos can just handle higher pressure ratios (more boost) and spool faster b/c they don't have to spin as fast to make the same boost...which make some sense I guess, I just thought a bigger wheel would take longer to spool.

I was hoping to get some feedback from some guys running regular v & h trims too. It looks like surge could be a problem, but I'm no expert. The more I read on them the less promising they seem though.

I was just looking to find a good turbo choice in between a 16g and 50 trim (besides a 20g) as far as both air flow and spool. The GT3251 looked promising at first too, but the more I read...the less convinced I become. Oh well.
