I'm a bit curious how you can call the Turbo IV (the VariableNozzleTurbo
Intercooled) 'limited' on the top end. At full boost it engaged the bleed off
valve that was set to 15 psi. You see, I owned a 1990 VNT Intercooled Shadow
ES. That car could kick the pituzzi's outta my Dakota. I regularly raced
Porsche's and 5.0 Mustangs, trouncing them soundly. I could smoke rubber in
3rd gear with a rev and a clutch drop. So where the 'top end' limit is that
you refer to, I'd like to know: I never found it. I had the car over 130 mph
and it still had room to go, but the aerodynamics of the Shadow didn't let it
get any faster as the car started to get squirrley. The VNT Intercooled
Shadows were the most powerful versions of those cars ever made. That in-line
four produced 210 ft lbs of torque at 3K rpms with the VNT Intercooled turbo
on it. The later Spirit R/T (at 200+hp) didn't get that high, and had mondo
turbo lag (drove one, hated it). Not bad for an SHOC engine that produced 174
hp stock. That turbo kicked major tushy and had no wastegate!
Chrysler sold the Turbo IV design to Honda for use on their race cars. You
can now buy an aftermarket turbo similar to the VNT from Garrett. They call
it their "Variable Geometry" turbo.

VNT's came in 89 & 90, overall better than a TII but limited on the top end.
their main gain to fame is the spool up time at low rpm's. makes highway
passing a breeze supposedly without needing to downshift. I have a few links
on them as well if anyone is that interested.
