331 sbf/ tea 205 twisted wedge heads/ f-cam/ tfs track heat intake. on3 hot side. master power ptrm 0.96a/r 76mm turbo. made 601rwhp/580tq at 5500 rpm but was down to 450 by 6200. 12psi/ 12 degrees of timing. i have since upgraded to a s480 t4 1.25 a/r 96mm exhaust wheel. changed from 3" downpipe to 4" downpipe. 3" x pipe with flowmasters and 2.5 tailpipes
new turbo results. 740rwhp and 620tq at 6500 starts building boost at 4000 reaches target of 16lb at 6000. It is rather laggy but pulls like a train. I will be taking it to the track this weekend to see what it will do.

this is a great thread i wish more people would contribute to since i always thought these combos had huge turbines

I have changed turbos again. TC 78/75 clone with t4 .96 a/r from VS racing. Feels much spunkier. No new numbers yet but seat of pants o meter says it is much better.

I am new to turbochargers and ive tried using online calculators and im confused as hell. i race N/A big block on dirt circle tracks so i have a good handle on mechanic just not when it comes to boost. i am building a 70 ford torinio where i took the stock 351c and upgraded it to a 410c with aluminum heads and intake and comp cam they recomended for turbo applications. i have not bought anything for the turbo system yet trying to get some ideas and references before i drop the cash. currently looking at the PT6766 CEA would like to use precision products, contacted them and they had me way out in left field with a set up to make 1200hp. this is going to be a sleeper car that i can drive around and the stomp on some rice burns when needed lol.

 

you make a run down the strip before hell freezes over the season? or is it already too late in PA?

 

Philly, I got out a few weeks ago, if you check my build thread I have it all there. I am hoping to get out next Saturday but I'm not sure if the weather is going to hold out. If not it will be done for the winter and I am going to have some things done I have been wanting to.
