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

SurfDog · 05-03-2015, 08:43 PM

Ive kept my limit at 7500 (even at track days) waiting for something like this. Wet sump is a bit heavy and very expensive that Ive seen...

Subed to see how this one goes

(Edit I just had a chat with Z1 and they apparently run 7800 rpm all day on their track cars with no problems. I'm sticking with 7500 anyhow just to be safe until I upgrade my oil pump/sump)

But dont get me wrong, if I could have a 9k TT Z I would rev to redline even if it doesnt make more power

There is a guy that spins an evo at 12k and makes god like power. Takes some deep pockets to make it work.

I guess he is running a humongous turbo and in order to keep it "spooled up" he needs to rev that high. And yes, deeeeeep pockets are needed since at those levels of rpm's there is something giving way all the time.
I remember the Mazda RX-7 when people where pushing the 9,500 rpm band and flywheels were coming of the vehicle thus injuring the drivers. But it can happen in any engine that spins that fast.

Geez, thats not cool

MR.nismo · 05-04-2015, 05:14 PM

What's not cool? The flywheel severing the driver's feet and injuring others or revving that high?

I know what you meant.

Elmo370z · 05-05-2015, 12:14 AM

I like my feet hahah

I knew I had this pic somewhere.

Elmo370z · 05-10-2015, 02:57 AM

Think the Revving 9k with a good manifold like 1slow370z and jun cams could make 400whp on a stock block or with some head work if that is even possible?

BGTV8 · 05-10-2015, 03:22 AM

How long do you want it to last ..........

Elmo370z · 05-10-2015, 08:34 AM

Talking as I will not drive the car hard. More for pleasure and the mind set if it blows rebuild the motor. I figure it is like boosting the car for max power as long as you don't abuse it, te car will last. What are your thoughts.

Elmo370z · 05-10-2015, 08:44 AM

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.
