Well we've been in contacts back and forth, I haven't heard from them lately, can't hurt to ask, hey it's a free bump after all . Anyway, reguarding the turbo kit, did you guys run a scavange pump?

 

Why don't you just show us all. How did we mistreat anyone, *sigh* must we go over one blown engine over and over again? We treated "him" very fairly. Now if you want to get into details you can PM us, Call us or E-Mail us. Or better yet start an individual thread pertaining to the topic.

 

Strangely, our Altima clutch (stock) has been holding up to 360WHP for quite some time now. Have you guys thought of the JWT Flywheel/Clutch combo? Cheap, readily available and very high quality.

 

Who are you the my350Z Gestapo. I can post what I choose to post. And I will tell as many people as like what happened. You may have taken care of ONE guy. But your actions and attitude towards the entire COMMUNITY is what I question. I have the right to warn my fellow Enthusiasts if a company has shown people that they may be questionable. Anyone on this boad can go over to www.b15sentra.net and read your posts and the amount of BS you dropped on there. I want to make sure the same thing doesn't happen to this community. So if you have cleaned up your act and your rep than prove it. Don't run your mouth to me and try to tell me what I can't and can do.

 

Darryl,

Could you reply to this post? I'm sure you just missed it. Thanks.

 

Any updates?

Here's our largest finding. As many of you know, fueling is key when it comes to turbocharging the 350z. This is what we've found:

The fuel system in the 350z is terrible. It definitely cannot support high horsepower modifcations. When we originally designed the prototype, we installed the larger 440cc injectors and the Greddy E-Manage. This is something we always do first with any of our turbo kits. When we hit full boost, we monitor fuel pressure to see if the factory fuel pump can flow enough. Fuel pressure began to drop fast so we decided to upgrade the fuel pump to a standard Walbro 255lph high-pressure version. With any other car, this would've solved the problem. It didn't. Fuel pressure still began dropping in boost. After scratching our heads for a while we decided to add a fuel return line as well as a boost dependant fuel pressure regulator. Now, this really should've did the trick. It didn't. We were stumped.

It was suggested that we try the Aeromotive Digital FMU as it seemed to have worked for so many other setups. In all honesty, we would never use an FMU of any sort, digital or not. The DFMU is a "band-aid" solution in our opinion. We all need to recognize that it's a voltage based pump. Changes in voltage will reflect fuel flow. This is how it works. When there's more fuel needed, voltage is increased to the pump and voila, more fuel pressure. Have you guys ever noticed how fuel pump voltage fluctuates when different loads are applied? Anything that demands a nice amount of voltage will do this. Headlights, even a car stereo system. When voltage drops slightly, you're going to lose voltage to that inline fuel pump and air/fuel mixtures will go leaner. In our opinion, this is the main reason why so many have not been able to hold a consistent day to day tune. Possibly a reason why there are so many blown motors with this setup.

Without giving away too much, all we can say is that we've worked out all the fuel problems and have solid pressure and air/fuel mixtures right to redline. We've developed a complete fuel system that will support well over 600whp.

We've been in this business for over 12 years now and if there's one thing we've learned is that there are far too many "copy-cat" companies on the market.

The twin turbo kit will be released soon and will ship with the complete fuel system. The fuel system will also be available separately for all of those running a different turbo or supercharger setup.

Thanks!

Darryl

 

awesome!

 

Sounds good, quick question.
Does it control timing also or is this a fuel only solution?
Thanks
Gary

 

Timing is not so much a problem as we've successfully gotten the Greddy E-Manage to retard timing.

Only fueling seems to be a problem.

Darryl

 

I am very interested in your fuel setup. I am currently running an in-tank walbro 255 lph and an inline walbro connected to the DFMU. The fuel curve stays where it should, but is very choppy. I hope to smooth it out with the e-manage, but would switch to your setup in a heartbeat if it holds a solid a/f mixture. I can't wait to see the finished product. Good work Darryl!

 

AWESOME!!!

I can't wait to hear more.

 

The twin turbo kit will be released soon and will ship with the complete fuel system. The fuel system will also be available separately for all of those running a different turbo or supercharger setup.




Can you give us a timeframe when the release date will be?

 

Hey Darryl,

Have you encountered any problem with the timing retard function of the E-manage? Are you using the Greddy Ignition Harness? The reason I am asking is that i'm getting mixed results as Greddy is saying that their ignition harness will not work with the 350Z. They are currently working on a solution as the current state will fry the ignition coils. Just curious how you got this to work.

Thanks,
Jeff

 

Jeff,

Yes, we are using the Greddy Ignition Harness and have it working fine. We've yet to try advancing timing as we've never had the need to. Retarding definitely works.

We were actually the first to figure out the ignition harness on the Honda S2000. Many of the owners really didn't believe that we had figured it out since Greddy USA told everyone it wasn't possible. Needless to say there was a bit of childish name calling. In the end, we proved them all wrong.

In the past, there have been known coil burn outs due to the E-Manage. I have heard of this on Honda S2000/RSX, and Mitsubishi Evolution VIII. Generally, if the ignition was left on (engine not running) for an extended period of time some customers have had their coils burn out. That was with the previous version of E-Manage firmware. Since then all the units are being shipped with v1.36 firmware. We have never had a coil burn out on us (with or without the new firmware) but have heard of the problem occurring. I imagine Greddy themselves have experienced this problem on their own 350z. Again, we've never seen this problem first hand and our 350z runs fine with no coil problems! I guess if you're a little worried about it, don't leave the ignition on (with engine not running) too long! Or if you have to, disconnect the ignition harness.

Thanks,

Darryl

 

I second the interest in the release date for the fuel system...when is it going to be??

 

Thanks so much Darryl. I'll definitely keep this in mind.

 

everyone seems to have a problem with the fuel system but me I guess. I have the greddy TT kit with the pe 380cc injectors walbro pump and the aeromotive FPR thats boosts pressure 1 to 1. All I did is bypass the fpr in the tank, ran a return just outside the tank in the back,and ran a long vacum line. pressure starts at 51psi idle and in boost it rises to about 59-60. Gives me 11.2 afr till about 5800 and rises to 11.5 at 7100 now. 8psi of boost and 405rwhp and 380rwtq. I think this is a pretty good setup all around. darryl good luck with your kit and if you guys come out with something better, I might have to change my setup.

 

Maybe I missed your answer to this in the previous posts, but will this kit fit the G35?

 

I am glad you guys are taking the time to make sure that the proper amount of fuel gets there, especially during redline...I am excited to see the finished product. Good Luck.
