I had to reformat my hard drive so I dont have the logs to look to see exactly what boost level at what rpm I was getting . But with the stock IC set up . I believe I was at 5psi at just over 4000rpm , 6.5 @4500rpm , 8psi @5000rpm , 10psi @5500rpm , 13psi @6000rpm and after that the serp belt started to slip and only got to 13.9psi once but most the time it level off at 13.2psi . The new set up should allow me to build boost all the way to redline . I dont know if it will build it as fast because of the bigger IC , but we will see soon .

 

what kind of hp are you running booger ?

 

I was at 400whp on a Mustang dyno [ NO CORECTION to Dynojet numbers ] I was also running 15 degree's of timing advance . I should be able to put some timing back in . And with the new IC set up , flow much more air than before . I hope to gain at least 50 more whp

Have you gone to Vortech's web site ? You can see the compressor map for the S-trim there . Click on [ support ] to see the maps of all the trims . Might help to compare the two there
