Those with TA33C and PORTED heads?? how much BOOST??

[BLACKHAWK38]

Was just wondering those of you HOT air CARS WITH UPGRADED TA33C turbocharger and ported heads what kind of boost numbers with what chip and what octane gas??

I can go a little over 16-17 with my Riviera 206 roller motor in 3rd and 4th gear without knock on 100 octane.

Just changed over to 1.6 ration rocker arms and she seems to have alittle more up top.


Regards

I get the most out of 25psi at the track on 111 octane fuel. I normally run 20psi on the street. I am still fighting the car on some launch issues though but it won't pull any more above 25psi, kills the power. My heads are home ported but stock sized valves.

i mix in xylene and its around 100 octane i have seen 2.5 deg knk on my 2-3 shift but it fades away so i dont think its real that is at 20# of boost other than that t-link shows no knock, this wednesday i am oing out to the track again and think i caould get a little more boost.
