Turbo engine, to hood vent or not vent


Recommended Posts

Hello all, just a reminder of my build, stock 78 280z 2.8 but with a turbo on passenger side.  Running ms2, 370cc injectors, intercooled, 8psi, 3 core aluminum rad, stock clutch fan and shroud.

 

Im looking at carbon fiber hoods and have come across Rs and Seibon.  Have heard good things about Seibon, and mixed on Rs.  Rs’ carbon hood is $1400 and has hood vents in stock locations.  The Seibon hood can be had for $1000, but no vents.  Is a vented hood needed?  My temps are pretty good right now with the stock hood, in the humidity of this summer.  If I went with my turbo exhaust is heat wrapped, but my header is not wrapped or coated.  

Should I spend the extra $400 to have venting, or can I get by without?  I plan on p90 head swapping within a year to turn up the boast, might be better to vent.
