Vishnu STAGE 2....DONE

342 WHP on a DD dyno
339 Torque
on C16 fuel...that about 400 WHP on a Dynojet unit
On the factory top mount
On the factory airbox\
@ only 21#'s of boost

Car is wickedly fast...

Vishnu is back in the game

Post graphs, please.

Prefer baseline and Stage 2 HP vs torque and A/F ratio vs turbo boost. I want to see how fat the torque curve compares with stock. Is there significant advantage over stock if you are stuck with 91 octane pump gas (and subsequent lower boost and less ignition advance)?

Here u go
I don't have my stage one map


This just my street/race stage 2 setup...remember this on a DD dyno, where stock STIs only put down 210-215 hp

Thanks for posting the graph. It's a little small to make out the scale on the sides and bottom of the graph but I can see how the torque has really improved with no apparent loss at lower RPM.

Was this Stage 2 vs stock on pump gas?
