dmhenderson's Nismo '12 GTM supercharged build thread where I freak out a lot

[dmhenderson]

Pre-tune I'm making about 450 to the wheels. They're guessing I'll pick up another 10-20 in the tuning process and if I want to go higher, I need an exhaust designed for FI. I really don't want to take it above 500whp tbh though.

Other stuff I *could* do but will have to think about:
-Throttle bodies
-cat delete (most likely of the options)
-Plenum - does anyone know if there's an option for the 370 like there was for the 350?

I think you'll be pretty damn happy with 450-475whp to start. That's a nice chunk of power in a 3300lb car.

[dmhenderson]

Yeah I'm not going to mess with anything at all until I get a "feel" for the car. They put it to work on the dyno last night and said the stink from the header wrap is almost gone but then their internet connection went down and they weren't able to transfer over something they needed from GTM's cable.

Chris and I are heading up at noon.

Who makes throttle bodies for us? I haven't seen any yet. There aren't too many intake manifold options at this point. I haven't seen any spacers like the 350 had, so I'm guessing it's not something we need. The GTR manifold conversions are interesting, but there's no results and it costs a lot.

Just enjoy the 450-475 whp. It's a LOT of power. You may find you don't need more for a long time.

I'm not looking to seriously track the car so I don't know if I want to go try to win the 370z supercharger high score contest. I will find out in uh...3 hours :3

Why not? The prize for having the most hp on a stock block sc 370 is having to buy a new motor.

$5 says the **** eating grin you have on your face after the drive home won't go away until midnight.

Awesome!
I actually read all 21 pages lol!
Started from the bottom now you're here for sure!
Keep doing you, that's a great build!
Becareful with the motor though!

Dat feel bro <3.

Grats on the numbers! FWIW HP doesnt bend rods torque does so your engine will be safe for a long time. Safe and fast as **** haha

We will need to legally drive side by side on a nice stretch of highway and do the speed limit soon!

[carlitos_370z]

Don't get rid of the cats , I took mine off and put Berk HF cats on and loss 35 HP so I put the stock ones back on.

I would agree with this, but at the same time I have blown a couple stock cats so I am putting TP on when I get a retune in a few weeks. Hoping to fix my little idle issue and some other minor problems.
I think we VVEL is every solved with some exhaust cams opening up the exhaust more for SC will be better.
