I dint think his aware that you've been away from home lol

today is dyno day!!!

yep, we're all waiting for some awesome results

And we'll be waiting a couple hours. He's in Hawaii, right? That's quite a few hours difference. :rofl2:

Because we ALL are thinking of doing the same thing?

My prediction from experience.

Because parts have to work together/compliment each other & have good reason to be installed. I predict (NOT WISH!!) that the results will be disappointing or will not be posted. Sorry.

My only question is... Since there isn't a before dyno, why do we care about the after?

buzzkill!

it'll just be interesting to see what he has after all those mods because no one else has done this. We don't have a before dyno to reference, but we all have an idea of around how much our cars make with certain mods so it still gives you a ballpark (unless it's one of those ridiculously retarded high dynos). I don't think most of us are thinking of doing all this, but we just want to see the results and wish for the best for OP.

I didn't go there because
 

I never understood the whole thing....

I however agree with you. Different dynos & tuners can make 50 h.p or ????? difference. Also we may get the H.P. but just like DEpoint pointed out, we won't know the gain from a stock car.

No...he means you need a starting point for comparason purposes.

I think that's what I said in my last sentence. :confused:

I am at the dyno shop now I will post after

I'm an N/A buff and
 

I wish you the best of luck. Maybe there will be a mod or two that really works well for N/A cars.

Maybe you can ask the techs there for their thoughts/opinions on what the best mods would be if one were not able to do all that work.

Regardless of how much it puts down it'll higher then most NA 370z's!!

Thanks guys

no results?

I didn't want to explain what I meant by "will not be posted" I still won't because I hope I'm wrong.

How could the parts he installed be dissapointing? We know he isn't putting out 530whp like turboes do. He might just make 370-390ish and even then thay would be above average from an N/A 370z. Hell even if he made 340whp thay would still be above average. Yeah the cost wasn't pretty for that amount of power but we do know it'll last longer then a force inducted 370z putting out 530. I like this build. Seems like a safe build for a car like this. Its a win win for him.

OK-been avoiding this because don't want to be a downer all the time
 

It's the next day now so I won't feel so guilty in expressing my thoughts.
I avoided explaining my last 2 posts here.

Let's compare the car to our bodies. First I'm not into doing major heart surgery or heart transplant to a healthy heart. ("low mileage relatively new car).
Leaving that aside, if you had to do major heart surgery you would NOT be the one picking/choosing the heart parts used.("new cams, than changed mind & got different cams") Also you would not let your neighborhood general practitioner do brain or heart surgery.("local dealership building a race engine").

Whether it's stock car or formula car racing, the driver does not decide/instruct what & how to build the engine. Most he can do is offer suggestions. The engine built would also not be done by the local gas station but by the best racing engine builders you can find.

I hope I'm mistaken & the car is fine & a great success, and my comments sound stupid & foolish.

I never thought those cams would make significant gains anyways. Not gains worth the 5k he spent total on the build, or however much he spent. But we wont know till he posts up the numbers. He already said the build would have been worth it if he doesn't hit his goal of at least 350whp. I would have rather tried an HR head swap with some aggressive cams. But no matter what, VVEL is always going to be the achilles tendon on this car. And I doubt they'll ever be any cams worth installing on this platform. But lets just wait and see the numbers he made.

Ok guys, I spent all day at the dyno yesterday. More tuning is needed for the cams. The dyno graph shows a roller coaster. The tech is working with all his sources to figure out why the graph is doing this. He has never seen this before. I am happy with the throttle response and the overall tuning so far. The average peak hp was 300 and the torque was averaged at 264. Yes a little disappointed on the numbers but with more tuning I know I can achieve the power levels that I want. I know if people look at this this will discourage them from doing this build but with everything I am still very happy. I forgot to add that the dyno was a dyno pack. I take a look at the graph I have a lot more tuning to do as you can see. The temp was 93 degrees also.

300whp? A stock 370z with stillen g3 and exhaust can put out more then that......

There's a point where your really limited to how many NA mods you can do before it falls flat on its face. Cams IMO only benefit if you have a full head job (lol) NA and really help with big power numbers on FI projects.

Demmit, I hope at least hit 330...

Otherwise, Turbo it and I'm sure all the stuff you've done will be worth while.

I am changing the headers and doing the transmission upgrade so we will see. I have email uprev to have them take a look at it as well. The cycling just doesn't make sense.

I'll just put this out there...the tuners here aren't very VQ savy.

I say get a safe tune and gently drive her till your stateside. This place is a headache when it comes to mods and tuning

That's a very interesting looking dyno graph, I'm sure with some more tuning this thing is going to put down some great n/a numbers.

Yes I agree I am going to find out why it's doing that and see what the problem is and fix it. First step is I am going to hook the pcv system back up cause the arc oil catch can has you plug the breather ports on the valve covers and the intake manifold so that's the first step.

What does a stock 370 put down on that dyno?

I seriously doubt that it has anything to do with the pcv system. That dyno chart looks like the computer's confused as hell. I'd like to see what Uprev has to say about it. Don't get discouraged yet. You've done something nobody else has, of course it'll take some time to get the tune dialed in.

Someone fly Seb from Specialty Z over there to handle this and he'll be good.

I have emailed uprev and sent the pic of the chart and I will wait to see what they say. I am not discouraged yet I just want to figure out why so if anyone else sees this problem they know what to do to fix it

You should also ask the tuner what other Zs put down on their dyno to have a better perspective regarding your numbers.

The only NA Z that had more hp here in hawaii was 306hp.

Did you get your tune straightened out?

Not yet. The tune that I am going to try next is the one I received from uprev instead of the one that the tuner made here in hawaii. I am still working on it.

this wait is killin me

Me too. I'll bet it puts up much better numbers with a good tune. Whatever that was on the dyno sheet was terrible. I'm sure Uprev will get it sorted out.

Uprev has advise me to go to a dyno jet instead of the dynapack so I am going to try it on that. I am waiting for a couple of parts to come in as well.
