The compressor is a 62 trim-.60 A/R and the turbine is a 76 trim-.64 A/R… A lot of debate and time was wasted on deciding to keep the current setup or upgrade to the available .86 A/R housing – based on what I’ll be doing with the car this year I decided to keep the ridiculous fast spool and not sacrifice 400-500rpms for an extra 40-60whp… We choose to install a NOS kit for the drag strip and not compromise the street/road race setup.
Sharif should be finishing up the dyno tuning soon – current #’s @ ~15.5psi is a bit over 500whp on Sharifs’ dyno…

Ahhh so it's a 2860R (just like the 700bb except without the .86 A/R housing). That's sound reasoning for the application. N20 on top of that would be nuts - a blast for sure. Those turbos have more headroom if you use race fuel or meth (as another alternative). I think the compressor map is pretty efficient till about 21 psi - if it's the 2860R. The exhaust is 3.5" piping all the way back? Holy smokes! Would love to see pics.

Finally another AAM Fuel pump user. I was beginning to wonder if anyone else used one...Did you set it up as AAM recommended or did you run a return line from the Surge to the OEM tank?
How do you feel about the performance on the fuel end? Is it adequate?
Sorry about the OT, I couldn't resist. Those pictures just caught me off guard.

Cosworth Plenum has been performing great so far - no leaks and it's handling the nitrous system with out any issues...
Some dynos runs of Sharif tweaking the new mods...

Just to clarify... Your exhaust is 3.5" all the way from the down pipes to the mufflers? Also, looking at those picks it appears you don't have resonators. Is this correct?
So... How loud is your exhaust for daily street driving?
It's hard to tell from that dyno vid (of course) how loud that exhaust is at idle and partial throttle.

It's hard to tell from that dyno vid (of course) how loud that exhaust is at idle and partial throttle.The exhaust is actually pretty quiet when idling and/or cruising - but it get's REALLY loud when in boost...
Final dyno numbers should be coming today... Some pics Sharif sent me last night...
