Which is  ironic, since it's reputedly easy to get that much using the
ordinary (and  less expensive) mods : camshaft, compression & breathing.   Kas
Kastner claimed he could get more power with the ZS carbs than with  the
Lucas PI.



I have theoretically (by calculation versus actual dyno) obtained at least  
that much horsepower following Kas Kastner's race prep guidelines for cylinder  
head prep, etc; advice from Richard Good from Goodparts on camshaft/rockers,  
advice from Dick Stockton on carb tuning, ignition.......all from using a  
triple ZS carb setup with B1E Jag needles.
 
I've seen the Moss supercharger installed on a TR6 - it looks pretty slick  
and I'm told it runs very well and I suspect that it wasn't as difficult to  
"dial -in" as my setup was.  The supercharger wasn't available in 2002  when the 
bulk of my engine work was done as part of the restoration so I can't  speak 
to cost comparisons but, from what I've read and seen, the  supercharger kit 
seems to be a very nice power adder.  One thing that  appears to be evident 
with the supercharger is that the engine note in the  exhaust isn't as "TR6" like 
as stock or modified TR6's....it  sounds more "modern" - don't know how else 
to explain it!
