Pushing past 9k rpms! Wet sump solution...

If I decide to ever track I would set the rev limiter to 8 grand. Plus it would be badass to own one of the only few 400whp Na Z's. It crazy how far companies have come, my thread last year talking about making that power was out the question

Seriously? A few GTM teaser pics and "we've come so far"? There's still the same number of NA 400whp Zs out there since you first started talking about doing this. 1- Shamu's old car. IIRC, that's a built 4.0 with a bunch of other goodies that probably cost as much for the motor as it did for the Z to put it in. 1Slow spent a mint to hit ~375whp.

A 400whp NA Z is for bragging rights only. It will get smoked by a FI Z at the same hp level in a straight line and coming out of a corner. If you're down with spending 2x the money for the same hp and much less torque, go for it. It's a cool project from an engineering standpoint, but the end result may be pretty underwhelming out in the real world.

I don't know of any 400whp 370z on a stock block. As far as FI being superior on the track is all about the set up and driver. 400 whp would be bragging rights but, just imagine if someone could reach it and then build off that. Big learning curve people and companies could build off of. No other company besides gtm a and cj motorsports are even interested in the NA market. But I don't blame them when you can spend the same amount of money for a TT kit and make close to 700 whp. I just prefer a screaming NA MOTOR over forced induction.

Shamu hit that mark on a built 4.0 on E85, but it was a full race motor. Not something you could run on the street. 1Slow was fairly convinced he's need to open up the block to push his setup any farther than he already had.

Driver may have a lot to do with it, but all things being equal, the car with 50-100 extra foot pounds of torque is the faster car.

Last I checked, CJM was working on a manifold that would really only be a benefit for the boosted guys. From his own thread, he didn't expect a huge jump in power on a NA motor. And GTM will never be a viable source for anything as long as Sam is running the show.

There's just not enough people who mod 370s to justify something like this from a R&D standpoint. There's not enough of a market for it to be a good use of resources as a vendor. Unless you jump in there yourself and figure it out as you go, you'll end up waiting a long time for someone to blaze a trail for you.

Can't aruge with you. You do have a valid point. I just hope it makes decent gains because i plan on following 1slowz route. Just will take me a little longer to do it. Once i do purchases the cam i'll ask to fly him out to install the cam.

For phunk's manifold I'm just hoping it will make better gains than the existing manifold's that are out now, especially in top end power. I wonder in conjunction with jun cam and larger TB's and a higher redline how much more power could his manifold produce. I think the manifold will be limited to the cars being tested.
