My dyno results
 

I took my Z to see Sasha at SG Motorsport to get my car tuned (uprev). I figured he wouldn't get much out of my car because I thought it was running really good as it was, the dyno results show that I was right.

Specs,
Dyno- Dynapak

Intake- Stillen Gen 3
HFC- Berk
CBE- Berk

Somewhat related... I would like to thank Josh at Stillen for all his help. He was always quick to answer my questions re:Uprev, and was able to get a Osiris Standard cable and software out to me pronto!

This was a quick (crappy) iPhone shot I took walking back to my Z from grabbing a coffee on my way home from the tune.

Looks good. Did you get a baseline before modding or know about what other stock 370Z's put down on their dynapack?

No stock baseline runs. I bought the car with the Gen 3's on it. What you see is all mods before uprev and after uprev.

The shop had told me stock cars are approx 280hp... nothing concrete though, I didn't see graphs to back this up.

All of those numbers are in line with dynojet numbers -- sounds about right, and sounds like that dynpack is calibrated to read about the same as a dynojet.

Looks good, and neither over- nor underestimated -- congrats!

They told me up front that they can get anywhere from 6-15hp from an Uprev. I felt my car was running really well so I didn't expect to get much from the Uprev, which shows in the graph. The important thing to me is knowing that everything is now optimized to work together and I'm getting everything I can out of the car and the mods. Plus knowing I'm putting down a little over 300hp at the wheels doesn't hurt. ;)

I went to SG Motorsport because they are very reputable, honest and are true enthusiasts (check out some of his race videos)! And from what your saying it sounds like I made the right choice. Too bad they're closing.

If you make further changes down the road see if you can find a shop with a dynojet first rather than trying a different dynapack.

Dynapacks can be calibrated to read very close to dynojets, but it varies a bit from shop to shop -- looks like that one was within a few %, so to me those numbers are "correct" (really, any dyno can give you accurate numbers, but consistency from shop to shop is less with load holding dynos).

Anyway, I personally like dynojets for getting "true" measures simply there's not much to fiddle with on them -- everything is based on the speed at which you accelerate the known weight of a metal drum, and that value is consistent from shop to shop (some slight differences between older and newer models and I think between above and in-ground, but no where near the variance you see on mustang dynos between shops).

I might be getting it retuned next spring anyways. I did something stupid for this tuning, the car was running 94 octane. The problem is it's hard to find gas stations away from my house with 94 octane. (I wasn't thinking)

There is a shop just 5 minutes from my house that has a Dynojet. The only problem is... they are into old mustangs, and jacked up mullet cars. They wouldn't know what to do with my car. Now if I knew a thing or two about tuning I would ask to rent the dyno from them. The only other shop in the GTA that does Uprev has the Dynapak as well... hmm. I guess I should start reading up on tuning. lol

Noice numbers, been hesitant on spending the $$ with just about the same mods. Heard would only net a couple whp, but not in your case. Might bust out the $$ soon. How much was the cable and s/w? And did Josh set you up with the h/w s/w?

I bought the cable and software from Josh at Stillen. Just send him a PM and he'll give you a price. I bought it from him instead of Uprev directly because he was so helpful.

You don't need to buy the cable and software to get the tune though. I bought it because I wanted to be able to revert my ecu back to the stock tune in case the car had to go to the dealership for serious work. I live 2hrs away from anyone that does Uprev, if I was closer I would just have the shop change it back to stock when/if I needed and save the money of the cable/software. Having said that, I ended up paying $150 more doing it the way I did, compared to the cost of just getting the Uprev. So it was worth the money at the end of the day.

If you can find a good tuner he may come to you and then you can use whatever dyno you like ;)

Failing that, just go the to the dynapack. Good to learn about tuning, but if you want results rather than an experiment, best to stick with someone who has prior experience to make the adjustments and then learn from them:D

Going from 94 to 93 shouldn't make much of a difference -- going to 91 might tho'...

Hey Jordo... I keep seeing you talk about your dyno thread, but I can't find it anywhere... what am I missing here?

In "advanced search", search for my username (Jordo!) and for the following search terms: Proven Power Dyno Database.

Should be the first one that pops up.

I'm just concerned about having to use 91 octane when the car was tuned for 94 octane. Worried about knock, etc.

I'll have to see about tuning/tuners, it's really hit or miss in Ontario... Although my neighbour has a high 6-low-7 second "street legal" 63 Vette, I'll have to ask him who does his tuning. :driving:

Ask them how much timing was advanced. From my own dyno expereince, the Z doesn't seem to like much extra timing up top, so it may only have a degree or two -- that should be okay -- but best to check with your tuner.

I've been told that the motor has a pretty excellent knock detection system, and can adjust timing and VVEL to keep the motor running safely, so it may not matter at all.

At worst, it's a simple matter of just scaling back the ignition map by 1 degree at full tilt for extra safety.

That said, if the temps are getting cooler out in your area, you have even less to worry about.

Is the timing something I can check with Cipher or Osiris?

Congrats on the dyno and tune man. Those are pretty much the exact numbers I got...which isn't surprising considering we have the same mods. Did he increase your rev limit?

Jordan - I talked with Martin and he's going to meet me at my work sometime next week to adjust my shift speeds. I want it lightning fast!!

No the rev limit is the same. I rarely get it up that high anyways. Did you raise yours? Is your car AT?

Cool! Yeah, I'm used to it now. I like having it set on "tooth rattler" :D

Lol...my wife is going to need a neck brace when she drives with me.

Actually, it's still pretty gentle (though firmer than stock) in D or if you don't give it too much throttle -- the firmness is related to throttle position, RPM, and load.

Ah -- and I discovered something neat today: If you modulate your foot just a wee bit on the gear shift to give a bit less throttle, it will soften the shift considerably, even when otherwise driving pretty hard.

So, for example, floor it --> modulate throttle input slightly+shift--> resume flooring --> repeat.

With practice you won't lose much engine speed, but can make the shift as firm or gentle as you want.

Or just gun it and prepare the neck bace :icon17:

Yeah...I'm just going to have Martin turn it all the way up! :)

Good man -- let me know how you like it. It's not a tune for the meek, that's for sure :D

Good idea and thanks for the tip. Josh is a good guy and has set me up with some sweet deals in the past.

At Jordo. I have always like yourself only really compared dyno numbers with the dynojet. BUT in my opinion I like to have my car tuned on a dyno (mustang or whatever) that actually puts a load on the drum to simulate real driving conditions or close to it for the most part. What are your thoughts on this? The best tune in my opinion would be someone with alot of experience thats willing to ride with me down the interstate at about 150mph. Obviously that want happen, lol...

Go job going to SG ! unfortunatly they are closing which is where I always went for all of my Dyno time seat ! hehe

I did a baseline on that Dyno with my 2009 7AT and the result was 258 whp
the last time I went there fully modded (with bad timing problem probably due to my badly cracked flywheel) more datalog this weekend since I just got the car back from Nissan (replaced the whole AT tranny and flywheel)

I had 311 whp

with a full bolt-on exhaust I had 280whp
so your 303 whp is good with the setup you have :tup:

Great numbers! I had similar results with a similar setup Berk Uprev Tuned

Other than the road/track, a load bearing dyno is indeed best for tuning.

For measuring power at WOT, dynojet all the way! :tup:

I don't know why, but Sasha kept saying my car hit 306 hp and that it was pretty good considering my car based at 300 hp. So I'm not sure if there was more to my dyno that showed on his screen than we see on my printout graph.

Yeah, sucks that SG is closing, it's hard to find people that have the same kind of (or better) attention to detail that I have. Don't know what I'll do if I decide to go FI.

Thanks! Anything over 300 at the wheels was good for me. Your dyno looks good too!

i doubt you would have gained more than 3-5whp over what you got already ..
my advantage over you at 311 was my bigger throttle body / cai & maf tube / PPE long tube step header

before my 311 I had 299 with the shorty headers (stillen)


He didnt replied to my email yet , im calling him today for the 19th for a quick one !

Finally another brother on the east side of the GTA.

On another note, we should get our for a run sometime next year. It would be nice to see how my set-up runs next to yours.
I'm up in Peterborough.

Sounds good! I'm in Cobourg, we're nice and close. Give me a PM anytime.

Did you put your car away for the winter?
I've mine under the cover for a few weeks, but had to pull it out on sunday.

Do you know of any good cruise routes towards Cobourg?

I put my car away at the end of October. It's killing me because of the mild weather we've been having...

As far as cruise routes...hmm... Hwy 45, slow and boring but good scenery, Hwy 28 is too mundane... I'm going to have to do some more exploring this summer coming.

It's only been a few weeks for me, but days like today want me to pull her back out and take it for a quick spin.
Some good routes that I have driven are Hwy 2 through to Stirling / Campellford into Warkworth. Nice scenary and little police presence.
We'll hook up in the spring and go for a tour on some backroads.
