I had the engine exposed all day at the show. Trust me, I'm not on NOS.

 

From the dyno sheets at: http://www.350zforum.com/ , it looks like the torque drops off at around 6300 rpms. That dyno sheet jesse posted kinda cuts off right around 6300 rpms so its too hard to judge.

I think that dyno is just one of the more optamistic dynoes. If someone can make those numbers at Mossy and then drive down to another brand of dyno, like Dyno Jet, and still make numbers within +/- 5 rwhp, then we can make some real conclusions.

 

Screw the doubters! Richard and datspeed you have nothing to prove. Just enjoy your cars. Whether the dyno numbers are right or wrong, we know Richard had a baseline on the same dyno, and came within the normal range of stock dynos, so he definitely had considerable gains. Datspeed, did you do a baseline?

 

Here's the deal with the exhaust. I'm the owner of Speed Alliance in San Diego. We are the sole distributor of Vertex Body Kits from Japan. Apex gave me the exhaust to try out and keep. In return we gave them some Vertex side skirts for their Toyota Soarer. Don't know if the exhaust they gave me is better. Highly doubt it, if it was better, then they would have produced that exhaust here in the U.S. For some reason, they are producing this particular exhaust in Japan only. Just telling you the facts man.

 

Nope. Had mods before I came to the show. I don't really care if it's correct or not, the car just feels fast as hell. Isn't that what counts?

 

So what are the other mods that you had prior to the show that prevented a baseline dyno?

 

Is there a website that I can go to and see where in Japan they are selling these?

Also is the y-pipe something custom that you built?

 

It must be those "secret" mods that he isn't telling us about that did it!

 

Well, I PM'd Richard also and offered to pay for his pull at the Socal Dyno day if I can't get Greg to take his car. I just want to get to the bottom of all this once and for all.

 

I would end all this discussion one way... RACING, I know some people would say that is risky, against the law, etc. I don't care! (no intention of picking up a fight ... BUT if I could go there, I would race all of them and THAT would without a doubt clarify if those cars are capable of that hp.
We are talking about low 13 second cars and close to 105mph in the 1/4. Not to mention above that speed, they should be monsters...

 

Isnt it odd he only got about 12 more tq with his mods? I would think he should have been getting more dont you think?

 

Looks like Richard and I now have a deal.

 

And to think I was there at Mossy that day. I could have done a dyno and maybe had more hp that any stock 350Z motor in the USA?

With this latest dyno post, it seems time to have the Mossy Z, Richards 350Z, and datspeed77 Z do a dyno test on a different dyno than the one used that weekend.

We either got some amazing Z's and all of us need to copy those set ups or something else is going on. The 282hp seems ressonable and I know Greg has been sure to be accurate. That dyno was done down in El Cajon. Maybe when they moved the dyno up to Oceanside, something was not calibrated correctly?

I believe that Greg dyno'ed about 291hp at the Mossy show with the same car/set up as the 282 hp dyno a couple of weeks prior. If that is an accurate statement, we are talking a margin of error of about 10hp. I assume that is a reasonable variation considering different days and temperatures. Am I correct or is that too much variation?

How hard is it to put the dyno sheets up for us to see? Base line runs too would be nice.

 

Can you post some pics of you mods. I'd definitely be interested in checking them out, especially the y-pipe since it sounds like that made the most difference.

-D'oh!

 

I doubt that it even hit the retail market yet. The Y-Pipe is custom. I had one of the guys who built the JBA Exhaust Manifolds for the Mustangs build me one.

 

All of my mods were done before the show.

 

i'm 90% gonna be at this dyno day. aside from richard and greg, i'm the only other person who posts on these forums that have nismo cams too??? i know jeff@performance will have the cams installed soon, not sure when though, but hopefully in time for this dyno day.

its gonna be a fun and interesting day!! ....allmotor shootout!! and then someone with a procharger will come and blow us all away

 

Yes, but what were the mods! We understand they were done before the show, but we want to know what they actually were.

 

Already told you!
