Because South America is still "Made in America", right? (Just down south... further south... past Texas... and we're ok with that)

1) I'm rear mount and
2) the 3" dumps about 24" from the turbo out the tailpipe.
Got my dyno numbers back. 550 rwhp @10 lbs boost
Not bad for rear mount.
Only issue I have is that I had put in 4.10 gears (before I decided to go FI). I burn through 1st so fast, I don't even see boost. Top out 3rd gear at about 115. Too low to finish the 1/4 mile.
First 1/4 mile run will be this Friday. Hope I do better than my 13.3 @101 before the turbo project. !!!

I was told that if I went with the journal bearing, the T70 would spool fine, but the T76 might have problems given my current setup. But when I mentioned that I may want to go forged bottom later and up the boost to > 10 psi, (and drop the rearend back down from 4.10 to 3.42), my guy said I should go with the T76 Ball Bearing. That way it will still spool good with current setup, and would give me the room to grow into the forged setup. The T76 BB will support >700 rwhp, which is more than I would ever want to see in a convertible.
Next steps, drop back down to 3.42 rearend (or 3.23... haven't firmly decided yet), then go forged bottom, then up the boost, then buy new tranny and driveshaft. Then see what else I can break.
