We recently swapped this turbo out for a BorgWarner s300sx3 turbo for better times in the 1/4 mile (we are keeping the FP 3794 for the Texas Mile in March). We made 675whp at 32psi on E85 on this set-up. We like the BW alot but will be putting the FP 3794 back on around February when we starting getting ready to break 800whp for the Texas Mile.
Very cool. What dyno did it make 709whp on? Why the BW over the FP in the 1/4? Does it spool earlier? I'm running the 3794 and it doesn't come alive until 6000. We are going to play with the tune and coat/wrap the header to see if that helps at all.
oh also, what did it run in the 1/4 with both turbos if you don't mind me asking?
