370Z on Lightspeeds Dyno
 

Yesterday there was a 370Z on Lightspeed Innovations dyno in RedDeer Was it a member here (i could give a description and owners name in case he dosent want to share I wont do that) and if so do you care to share your mods and dyno numbers?

It was me, I have most of Stillens bolt on's (gen3 cai, headers, cbe, hfc's, pulley) Not quite the numbers I was hopeing for, tuned with Cobb access port. Final numbers were 305hp, and 239ftlbs torque. Like I said a bit dissapointing however I gained 13 ftlbs at 2600rpm and he really cleaned up the air fuel ratio. Base run before tune was 300hp, and 232ftlbs torque. Numbers don't show it but it seems to climb thru the rpm band with a lot less effort, very smooth. How'd you know I was there?

I have been good friends with Cam for years I am buddies with his guys as well. I was there today wrapping up some crap on my car and seen your graph it looked really good (and I see alot dyno sheets come out of their over the years), not huge WHP gains but the torque under the curve gains looked great :tup: I bet it pulls alot harder now. I have heard from quite a few G35 guys they were disappointed in the numbers they got, don't forget we are at a much higher altitude than many of the Dynos you see here on the forums. The guys at Lightspeed seemed very impressed with your car.


You may have only minimal gains at peak but the numbers under the curve looked like a 20-26ft/lb (it might be more or less I just had a quick look while looking for one of my graphs) gain and thats why it seems to climb way harder through the rpms. I will take gains under the curve over peak gains I have rode in lots of cars before and after tuning the ones that impress me the most seem to be the ones that make large gains under the curve, they seem to pull much harder. A friend of mine just his EVO 9 tuned and it was similar to yours not huge gains at peak but under the curve was good the car felt like a totally different animal after the tune.

So true, pulls a lot harder now a lot more fun to drive can't wait till the sun comes out! I checked out pics of your car, nice job looks good and I'm sure it flies.

Was it Cam that tuned you? I'll be going to him sometime this summer to tune my nitrous if i can ever find 1 step colder spark plugs.

Scan of dyno? Curious to see where power was gained.

Tuning with that setup seems right on par.. the biggest thing with the combo of the bolt-ons and especially the HFCs and Headers is rounding out the air/fuel ratio.. glad you jumped on that.

What was the baseline before the mods?

It will be interesting to compare the results when I book my time with Cam to have a Cobb tune as well. I have a few different manufacturers of
bolt-ons compared to yours.

The only Stillen product I will have is the power steering cooler and maybe the Stillen oil cooler (only if RCZ gets off his *** and gets it off his car and sells it to me :stirthepot: ..... sooner is better than later :tiphat: )

I've decided to tune the Zuma before the "other goodies" arrive :happydance:

I'll give ya a PM when that time is booked

Cool! Wanna share your dyno charts here?

I've tried to go on their website a few times for weeks and it seems to be always down.

Posted pictures with charts on my profile

I didn't have a chance to dyno before adding parts as I had the cbe, and cai ordered before taking delivery of my car

damn i thought i started modding my car early...


btw, just looked at your dyno graph. That torqure, uh, curve is all over the place.

Heres mine with G3's. The curve, well it really isnt a curve.

Sure it is -- a nice platykurtic curve. Exactly what you want to see :D

his shouldnt be that jumpy, should be smooth like mine or at least smooth increasing curve.

Platy-wha??? :rofl2:

The before and after torque curves are similar, even though there are many "oscillations"...wonder why there were so many of them.

Oh, I thought you were referring to yours as not being a curve... duh :icon14:

It could just be an artifact of scaling/smoothing -- dynapack readings often look a little "lumpy".

Although I could swear I've seen another persons' dyno looking just like that on a dynojet... I need to see what the VVEL maps look like... tuning cam angle and lift is probably a b!tch to set right on these motors with a good bit of trial and error.

Flat -- if the torque curve were leptokurtic then something would be very wrong :D

Yeah, like I said, could just be artifactual, but it would be nice to see the VVEL and ignition maps...

I dont think its the scaling/smoothing. Its SAE corrected and also if you look closely you can see the HP graph matches the TQ graph...whenever the TQ drops, the HP power doesnt drop but increases abit slower.

So in other words chinook, you probably could get abit better results with abit more work on the tune. I'm not saying Cam or whoever did it, did a bad job, but from what i understand you are his first 370z to work on. Once again, hopefully he can do a good job with my car.

Yeah Snakes it was Cam, The more I drive the more I appreciate the job he did, so if he can get your torque curve a little better, you should be very happy! Did you get a dyno done before any of your mods?

Their website isn't working and no one to answer the phones. Couldn't enquire and book today.

Just spoke with a good friend of mine who tunes 350's and 370's. He seemed to feel the OEM VVEL maps were already pretty optimized without changing the manifold... hmm. Dunno.

It might be goos to make sure the ECU isn't pulling some timing due to light knock -- I believe the ECU is pretty aggressive with that on this car. Could be something like that if the AFR's aren't warbling in step with the torque "lumps".

How's it feel under load? Smooth or do you detect any hesitation?

Feels really smooth and I saw the tuner using headphones connected to a box reading knock sensor that was wired to the engine bay, so I'm guessing he was checking. I shoulda asked more questions I guess.

You're probably fine (curiously, the owners manual suggests that some light knock under load going up hills is to be expected :icon14: -- guess they have a good scalar map for knock or the pistons have meaty enough ringlands to not be an issue).

If it feels smooth under load and AFR's are stable (did they lean you out? I understand the OEM tune is quite rich!), I wouldn't worry too much about it.

Only dyno i have is with the G3's installed and my butt dyno felt a good increase when i installed them, so if im at 280hp now, i was probably around 265-270.

So i want to get my tune done so bad and get a AP but i really need a Oil Cooler and its going to be time to upgrade my brakes soon since im doing alot of tracking now. And now im leaning towards road racing instead of drag racing im actualy thinking of selling the nitrous kit.
