Not horsepower alone
The Nova is probably running into aerodynamic barriers... and 3300 lbs is fairly heavy so there is a weight penalty as well..What kind fo tires is another question to be answered..
Now if that engine was to be put in a pro stock chassis or a rail..lighter weight..better tires..better aerodynamics..and so forth then one might go 200 with that engine..
Just because there is a lot of power availabe does not always translate to speed or performance..Gotta use that power in the most efficient way..
hope tha tclears up your question a bit..
the procharger does look like a good unit tho I have not run one..It is very similar to the Paxton which has been around for 40 years or so that I know of..
I have tried most all of it and now do what is known to work..
