UpRev tuned @ Granite State Dyno 8/17
 

I'm starting this thread for my dyno session tomorrow at 9am. I will have a base run w/ FI 18" CBE and Stillen G3's. After, I'll install Motordyne ART pipes and do UpRev tuning.

I would imagine that I'm getting one run w/ the ART pipes before they start tuning, so I should somewhat see what the pipes have added to the party.

forza370z is stopping by and we'll have some before/after videos and dyno sheets. For those that are tuned, please feel free to add some advice.

Things I have so far from searching:

Maps:
Stock
valet
anti-theft
tuned 93
tuned 93 wstar's smooth throttle

Review: Granite State
Alex and the guys were very nice and knowledgeable. I made 3 base runs for $80 and was only charged 1 hour for test pipe install (labor $80/hr). I couldn't complain about that. They made quick work and had me tuning in no time.

Pricing:
labor $80/hr
uprev tune/dyno $500
dyno 3 runs $80
Re-tune/dyno $150

I spoke to Alex a week later about tweaking my tune. I wanted fan control to be changed and offered to have me come in free of charge! If you guys ever want work done, I would highly recommend them to anyone in the NE area. Some other tuners/shops that I won't name, charge $120/labor and a lot more for re-tuning. I was also told that Alex tunes for other big name shops in the NE area.

Post tune review and findings

Very interested in seeing the results between stock tune and TP/tune. Sub'd

Added base run w/ cbe and intake -- 80 degrees and 50% humidity

Nice.

I'm guessing 320whp, 260wtq after pipes and tune.

Sub'd for results.

Somewhat lack luster for numbers; I'm a bit heartbroken. We install test pipes and got 304/248 and then started tuning around 1:30pm. I'm not going to make excuses for heat and motor being heatsoaked -- it is what it is.

My final numbers never got any better than the 304/248 run which was just test pipes, no tune. A/F was corrected, he tried to add timing but it wouldn't allow more than 30 degrees when somewhat cool and 26 when heatsoaked.

Now w/ all that said, I feel the drivability of the vehicle is better than before. I feel like I have more midrange and car seems more responsive. I know it's not all about peak numbers, but I can't help but feel like I should've gotten more out of it. All in all, I'm happy w/ city driving, but I'm not w/ the numbers.

Maps:
Tuned 93, valet, Tuned 93 w/ wstar's throttle, same as 3, anti-theft. I'll post the sheet up in a bit

Change your filters in december and do some passes when its 50* out or so....then you will see your numbers you want.

Thanks; I'll definitely run it again when it's cooler out.

Rule #1 with anything performance...eliminate heat. I plan on redynoing my z in the winter and I plan on throwing bags of ice on top of the intake manifold along with the coolant line delete from the throttle bodies.

I'm really bummed about the peak numbers. Not so much that they're not high enough, but that they didn't move from test pipe run and when tuning started.

I should have the files tomorrow for upload. For now, I'll post pics.

Depending on what you have on your car for mods tps won't net a lot of hp. When you have ambient temps that are that warm your car will start to cook on the dyno. When its cold out you will see better peak numbers. That's part of the reason you see cars doing dyno's at night at some shops because the weather is extremely cooler and less heat soak happens.

You will probably get around 310-315 once you change your filters and dyno run in the winter but I doubt anything higher than that.

The 2nd dyno sheet I added only has numbers from cbe/intake/tp, cbe/intake and cbe/intake. I should have the other files today to see what the tuning is actually doing. If you look at sheet 1 and then sheet 2, you'll see that two of the sheet 1 runs made it on to sheet 2.

I have no idea what the tuning is doing because it's not sheet 2 at all, and the best numbers of the day are on sheet 2 which is only cbe/intake/tp. That's why I'm really not happy.

Any runs after "runfile_22.drf" (304/248) on sheet 2 didn't make anymore peak hp/tq.

Just curious....what gear were you doing pulls in? Also what was the time between pulls?

4th and he would do 3 - 5 pulls. He let it rest probably about 2 - 3 times w/ about 10- 15 mins w/ fans on it. I have to look at my videos to confirm, but that seems about right.

When we talked about what was done. They only thing that was mentioned was corrected A/F and adding timing. IDK if I got the full explanation or not.

Having the right a to f makes all the difference. The reason you didnt see the numbers you wanted was because it wasn't a direct drive dyno....meanimg he meeded to do 5th gear pull. 5th has a 1:1 ratio where 4th is 1.something to 1. With as warm as it was you should be close to my numbers.

Problem w/ 5th is I need to exceed 155 mph which hit's governor. That would've made all my other runs in 4th w/o tune kind of useless or would've made all my runs w/o a tune, short.

I think you're right though. Next time I go, I'll run in 5th and then tune it from there.

Did you run in 5th or 4th? I totally forgot, but I wanted to remind myself to have him run it once in 5th.

I had my governor takenn off my car. 5th gear is direct drive. Also what type of dyno was it? Name bramd?

DynoJet 224X 2wd dyno. I should have files by tomorrow, tuner is real nice guy and is busy. It'll be nice to see power under the curve. I can definitely feel it; I drove my car and then drove Forza370z's nismo on a closed road and could feel my low - mid stand out more. It revs easier and quicker.

I will say it again; I'm happy w/ city driving. I'm just bothered by peak hp/tq.

I think you cant exceed a certain speed on the dyno. According to your previous post...in 4th you couldnt hit your target speed of 155mph. I think you accidently got it twisted. On the dynojet I was on I couldnt exceed 163.

If you want more midrange you should consider the motordyne manifold. The runners in it are a little longer creating more midrange power. We habe a similar setup so I can attest that I love the way my car performs.

Just remember, the only reason why your car read lower was because of the gear. Also possibly temp. Just curious though what was your targeted hp?

315/255 and i would've been happy.

I should've done more research. I'm finding things I want to change/add to my tune (mainly fan control).

5th?? I thought it should be 4th.. I know autos are different but mine is always in 4th.
Not sure about the type of dyno but I know on the mustangs(low) I made 298 WHP and 230WTRQ back when I did my tune with just I:E. But your numbers dont look that bad.

Below are listed the gear ratios and final drive ratios of the 370Z's manual transmission:

Gear Ratios (Manual)

1st 3.794

2nd 2.324
3rd 1.624
4th 1.271
5th 1.000
6th 0.794
Reverse 3.446
Final Drive 3.692

This should help explain what I said. If you dyno in 5th you get the direct drive power being put to the wheels instead of it being multipled down.

Most of the tuners I know tune in 4th but make final runs on 5th 1:1 ratio. You should have broken your target whp/trq easily with your setup.

Most people posting dyno sheets with ~270+ Ft Lbs torque numbers N/A are dynoing in 4th gear.

Multiply the torque numbers by 0.787 and you'll have the "real" wheel torque number.

This doesn't necessarily apply to Dynojets... the way they measure torque seems to be very different than other dynos, I myself have sheets showing torque in the 260's and I know they were done in 5th, then I have sheets from the next day on a Mustang with power very close and the torque in the 230's.

So which dyno is considered the most reliable? I always thought it was a dynojet.

It is.

Still waiting on dyno files. I'm going to bug him again for it.

I actually have a few good runs that made 306-308. The power curve on 306 shows the best in terms of performance gain, so I used that and posted it.
