wow, a lot of great information here.

Makes me consider the SC route vice the TT... awesome work, GTM.

Here is the info on the new bypass valve set up, this is a fully adjustable valve with a 38mm port size vs the older version that was 24mm non adjustable .

This news definitely made my day, VVEL has greatly limited tuning and I'm blown away by this news. My only question/concern is that will it be via uprev or will those already with uprev be forced to opt for a completely new possibly standalone setup. While I want vvel cracked standalone engine management is $$$$.

No it is not via the Uprev and it may never be sense even Nissan does not control the VVEL via the ecu, it has its separate stand alone controller to do that, Our short term goal is to have full control over the engine and to do so we will be utilizing an external software and hardware to control the the cam phasing and the VVEL separately. keep in mind that having more control is not always better, More control does become more beneficial for complex modifications like supercharging an engine witch such high VE like the VQ37VHR but you may never be able to out do the factory valve timing for a stock engine set up.

Stay tuned

Hey Sam,

You PM'd the other day after almost two months from my last PM to you. You said you got behind and that you would have my info soon. I see you are on the boards here so I was wondering why you haven't PM'd me back?

Don't wanna make a sell?

Sam, you are running blow-through MAF, right? Why not just do a VTA BOV? The MAFs are up by the intake plenum, no?

You can vent the valve to atmosphere, You can run the setup both ways

Sam

So is the vent return just for noise reasons?

You mentioned you have test cars at the shop. Do you have a S/C and TT test car? I would love to get a feel for these both as I am trying to decide what car to get this spring and a GTM'ed 370Z is in a dead-heat with an EVO X.

I got to

the stg1 supercharged and stg1 twin turbocharged shop-monster back to back around the block and WoW!!! Be warned, you will hate your stock car.......

Both cars are very tidy under the hood with a seamless integration of electronics, they could have come from Nissan that way, both idle well, quiet, tame and civilized in traffic.... The S-charged car delivers the power in a very linear fashion resembling the stock power curve but higher and significantly better up top.... a lot more power on demand. This bolt-on setup is very livable for daily use and a ton of controlled fun, as if you dropped a V8 in the Z, a serious transformation guaranteed to keep you grinning

The Turbo is a hooligan, especially in the low gears, the VDC will completely cut you off at WOT and if you turn it off without the GTM-tuned traction control system, you better know what you're doing!!! Guaranteed to satisfy any mad power craving if the supercharged doesn't do it, either way, you would have to relearn how to drive your car... the character and limitations change.

I'm gonna hold off on discussing my plans for the Z until they become a reality, thanks GTM
