At UpRev getting the 370 Tuned
 

At Uprev been on the dyno since 1:00 CST added about 18 HP at the rear wheels:tup:

Nice Job to Rich and the guys at UpRev:driving:

Can you share the dyno plots please... also what mods?

Mod list please, nice gains. :)

Talk about a wave of tunes lately hahaha, Holy ****.

18whp gain? where did you start from and what mods?

Dyno?

Stillen Cat Back exhaust
Stillen Intake
Berk HFC

I will post Results soon started around 277 RWHP
ended up at 295 RWHP or so. Drove home to San Antonio from Austin what a differance it made
The Titan is next !

277? Did you get the stillen short rams?

Only 18hp? I was thinking you would get around 30-35hp with that mod set up. What was your torque gain?

Torque went from 232.65 to 245.47 :tup:
Trying to get the scanner to work with Windows7 no luck yet

Yes when I got them they did not have the long ones

all those mods/w tune only netted 18whp? or you were sitting at 277whp with the I/E/HFC's and pulled an additional 18whp with the tune?

Yes Started at 277.72 with the I/E/hfc's picked it up to 295.13:tup:

Very impressive, although I must say, that dyno must read hella low, I made 283 from 267 with just HFC's..

so an 18 rwhp gain just from the tune isnt bad. looks like the tune really tweaked in the mods.

What kind of dyno?

nice! you'll get more gain out of the titan i'm willing to wager. rich was telling me when i was there that they can normally get close to 30hp out of titans with a few bolt ons because of the conservative tune from the factory or something like that

I believe Uprev uses dynojet at their facility, but I could be wrong.

Looks like a DynoJet is what UpRev has in there shop. I took some video will post soon

its a little less impressive on a dynojet, but its still a good gain... its actually on pair with all the other people getting tunes...

Yeah I'm surprised he's not into the 300's, considering his mods. Caneman -- is your car manual or automatic?

Edit: I just went back through the thread and noticed that he doesn't have the G3 intakes. That would account for some of the difference.

It is a AT Sport/Touring
Rich at UpRev was saying that the G3 vs the short tube is about the same because the longer tubes get hotter than the smaller tubes.
I'm not sure if it makes that much difference. :stirthepot:

Hey man, I'm just trying to come up with logical reasons your car isn't making more power. ;) I'm thinking the AT has something to do with hit. I know wstar also found that his car (also AT) made less power on the dyno. But I think he said it has something to do with the difficulty of getting a 1:1 gear ratio with the AT. In other words, it's not necessarily that AT cars are putting less power to the wheels than MT per se. It's just harder to get dynos to read right due to the gear ratio thing. (Not that it matters vis-a-vis measuring gains, mind you.)

5th gear is a 1:1 on the 7AT.

Also the final drive has different ratios on the 7AT. Probably the combination of the lower ratios in the transmission and shorter set in the rear end is what makes the 7AT faster in the 1/4 mile...that and the fast shift times! :)

Seriously though, between those two items (5th being 1:1, FD ratio's being different) - that will reflect differently on the dyno if it's not compensated for.

Might be better to look at it as a percentage gain rather than hard numbers....

6.1% gain is not bad from *just* a tune...

:iagree: It's not bad at all, not bad at all.

I found wstar's dyno thread, btw. http://www.the370z.com/intake-exhaus...c-e-dynod.html

This is what I was trying to remember regarding the problem he encountered doing a dyno with the 7AT:

"Attempted 5th gear run on same DynoJet, doesn't fly because with the 7AT's rear-end ratio, you can't top out the revs in 5th due to the stock ECU's speed limiter tripping at 160 mph."

Yea I was wondering the same thing why it did'nt show some of the gains of the MT ? The way they measured the Dyno was using the paddle shifters and only used 1 thru 4 gears.After the last cool down also tryed 104 octane fuel to see if we gained anymore HP it kept the gains the same even after the engine heated up that was all.
Overall I'm very happy with the tune this was the 1st 370 w/mods they have done at UpRev so as things progress I'm sure they will find new ways to pull more HP at of the great VQ37 Engine

I forgot one mod the Fog light I think I got 50 HP out of it :icon18:

Your numbers actually make perfect sense now. If they were measured in 4th gear, they will come in a little lower. That true even with a MT car. I know this because when I did one of my dyno runs on a DynoJet a few months back, the tech accidentally did it in 4th. If I remember correctly, it made a difference of about -10whp.

What is the ideal gear for a 6MT?

5th.

Ah, thank you, do not remember what my last dyno was in but he said he did it in the same gear as before so if mine was low on one it was low on the next.

Sharif was telling me that with Dyno Dynamics, he can adjust the settings to compensate for whatever gear he's running the car in. So as long as your guy had the settings correct, it shouldn't matter. DynoJets do not have that setting adjustment, however, so it's more important to be in the correct gear on a DynoJet if possible.

no shyt bro? I dyno'ed in 4th every time i've done it, dyno'ed from 267 to 283 w/ HFC's in 4th, so your saying I could actually be putting down more?

That sounds about right, the guys at Engine Logics stated it did not matter what gear I did the run in as this is a Dyno Dynamics.

Yes, if you're dyno'ing on DynoJet. Here's a pic of the screen from that day they accidentally did some runs in 4th instead of 5th, to give you a better idea.

RunFiles 001 and 003 were done in 4th. 002 and 004 were done in 5th.

Actually, I think a big part of the difference in power is in fact the intakes. I disagree with Rich on that note.

Would it make much of a difference on a dyno though? Because the hood would've been open, right?

He might gain 5-8 more HP with stillen G3, because the hood open with short ram intakes will create false results. We saw that with me when I did Takeda, I did close hood tests and Takeda did open hood test and they saw gains while I did not.

Precisely what I was on.

I agree as mine dynoed 293 rwhp on UPREVs dyno with my mods. And I have a HR 350z.

Had my 370z dynoed with Uprev at Indecracing in Kent, WA. today. They were the 3rd dealer in the US to sign up with Uprev when they started and know their stuff. This was their first 370z they have done and there is a learning curve involved. He was on the phone to Uprev a couple of times and Uprev was in the process of doing another 370z at the same time. He installed five maps: performance, economy, stock, valet and theft. It is controlled with the cruise control switches. I was there for about five hours with about half the time on the dyno. Lawrence, the owner, spent about 45 minutes smoothing out the A/F maps on his computer. A couple of notes: the graph is SAE corrected (not sure if that is what everyone else is showing - uncorrected [actual horsepower] was over 300. The runs were made in 4th gear so numbers may be a little low. Interestingly, my car seems to like a rich mixture and when he leaned it out more it started to lose power. Also, Uprev is working on cam adjustments but that is somewhere down the road. My mods are R2C intake(with Modshack vent), Berk HFCs and smaller crank pulley. They use a DynoJet, model 248C.

That's a very respectable gain. Congrats!
