We recently had the opportunity to complete a very interesting Naturally Aspirated project on a customer's 2012 Nismo 370Z. Allison (allystephy on here) pretty much gave me free reign on the project, her only request being that I make more Naturally Aspirated power than I previously had while working at Z1. My previous best was low-mid 340's on pump gas, and high 340's on E85, needless to say, after a little more R&D on the VQ37 we made it happen.
Modifications include:
TSM Modified aFe Intakes
TSM Fuel system upgrade
TSM Proprietary Modifcations
Z1 Headers
Tomei Test Pipes
Tomei Ti Cat-back exhaust
TSM Dyno Tuning with VVEL Calibration
I believe this to be the highest HP ever recorded by a Stock Longblock Naturally Aspirated 370Z/G37 on a Dynojet.
This car made 346rwhp on our in house DynoJet on 93 Octane pump gas.
357rwhp on E85
Here's a comparison to a stock Nismo 370Z we previously dynoed.
Stock Vs Pump Vs E85
