Hopefully getting tuned with UpRev today
 

As it turns out my schedule unexpectedly cleared up today. I'm going to go visit Alex at Performance Motorsport in Smithtown after I pick up my modified XboX that can play burnt games. Double treat me for me today? I hope so. So in case anyone is wondering my previous dyno run was on a dynojet with nothing but a set of unresonated GTM test pipes. I made 296.xx whp. Performance Motorsport uses a Mustang Dyno and I'll be getting on there with Fast Intention Long Tube Headers, true duel straight pipes 2.5" to a stock muffler, and an oil cooler. Anyone want to wager how much whp I'll put down before and after the tune?

Vids to be up later today...I hope :tiphat:.

Looking forward to results

False Start :facepalm:. It was cool to meet with Alex and the guys at Performance Motorsport made an appointment for dyno tuning scheduled for Tuesday 9:30AM. I'll report back then :hello:.

In for results!

In :)

I'm in for results!

i guess no more than 300.

depends on the brand of dyno, if its a mustang... wont break 300. No matter what the number is , its good to fine tune the afr... :)

You guys are guessing no more then 300 wheel. Ouch, I watched a Nismo with FI CBE, TP, and a CAI and he made 338 wheel after the Tune. All on this same dyno that he's gonna be getting his car dynoed on.

This wasnt done on a mustang dyno.

Are you just saying that cause you think it cant happen or do you know?? Someone correct me if I'm wrong but the dyno at performance motorsports is a Mustang.

A 370Z was just tested at my local shop for Import Tuner magazine.

Stillen CAI, HFC, CBE with Uprev tune

Result:
(Mustang Dyno)

326HP @ 7150 RPM
261 lb-ft @ 4250 RPM

Run Details

Yup, and it's not the first time an Uprev-tuned 370Z with full bolt-ons has made over 325HP.

+1 :tiphat:

Went by today, ran into an unfortunate hiccup. All in all its going to be another week. I have a BIG exhaust leak that needs to be addressed first :(. I must say that the guys at Performance Motorsport are real stand up guys. I did get on the dyno today and yes it is a Mustang Dyno but results are inconclusive since we didn't want to tune over the problem caused by the exhaust leak.

Oh man sorry to hear that. Hope you get her going quickly!

Yeah, she's fine but I can't tune her like that and then fix it and get a retune that would be dumb. I'm not upset over the fix or the cost, it could have been worse and it's a lesson learned though I would have been happier without learning the hard way.

damn sorry to hear

I guess the reason why I'm not really bummed is because I know I can get 330whp out of her but I won't quantify that until next Tuesday.

that sucks man... next week. where is the leak?

I'll tell you after I get it fixed^^ otherwise I'll just anger myself and I've thus far done a good job of not getting mad.

Glad you had a positive experience Rez!

It was unfortunate that there was a minor repair that needs to be done before we can tune the car correctly, but no worriews man. Next week we'll get this going.

Our facility uses a Mustang 2WD/ AWD Chassis Dynamometer and, a SuperFlo engine dynamometer as well for engine builds and our race program. Some say its reads higher and some say it reads lower... We're pretty much in line with the run posted by 370Steve.

As a precaution, I am anxiously waiting for the new software for our dyno, which Mustang claims, is only a week or two away. Dyno gets calibrated weekly to ensure accuracy.

Click the vid on my sig to see the dyno ;)

I'll see you next week Rez :)

Update: dropped off the car at the express drop off this evening. Alex will have it waiting for him tomorrow morning. Picking her up Friday, she'll probably be done Thursday but I'm working and I can't make it out to Smithtown and back to NYC in time.

you won't regret it, the dyno does seem to read high, but the power picked up by the tune is there regardless. I gained about 15hp/8tq after the uprev.

I probably would have gained more if I had intakes but I plan on going F.I. and I don't want to throw away the intakes in the trash can or take a hit on the resale. 320ish whp should keep me happy for now.

336WHP is almost 396HP at the flywheel on the 370Z which is very close to 400HP without forced induction. That's quite good.

I've been thinking, wouldn't someone get a majority of the gains associated with full boltons by going just hfcs and either a dyno tune or canned map?

^^ I would say something more like Long Tube Headers and a CBE, dynos have so far shown that the OEM intakes aren't all that restrictive until you go beyond 6800rpm.

Im going for a emissions passable daily driver set up. I just think hfcs really make a catback meaningless other than for sound. After reading the forums for a year now I think 30 whp isnt out of the question with hfcs and a proper tune. So for a grand on an na platform is damn good.

Actually it is out of the question. Prior to getting the long tube headers I had test pipes matched with the stock exhaust. Sound wise it was the best decision I made for little $. However on a grateful dynojet I made less than 300whp (296.4). HFC's will yield less power. The stock exhaust is to restrictive, the inlets for the y pipe are ~2in so with tp's or hfc's your still suffocating the exhaust.

I don't know how it is in Pittsburgh but unless you're on the sniffer you won't have a problem. NY uses an OBII, if you aren't throwing any codes, which I won't be then you'll pass. However, if you're dumb enough to go to an anal shop that will put your car up on a lift or crawl under they won't pass you even with hfc's because you "modified" the stock cats.

It's wishful thinking to get 30whp with HFC's and a tune, frankly hfc's don't make a big enough difference where I would even throw down for a tune. You would have to get it retuned again after add more bolt ons ie. intakes, pulleys, headers, etc.

My Nismo was the one that made 338whp n almost 260trq btw....

can you list your mods??

Those where some good numbers. I used your car as an example many times on this forum to prove that those numbers are possible with simple bolt-ons.

All problems have been addressed Rez! strapping on the dyno and tuning in a bit ;)

Thanx bro I appreciate it...and my mods are fast intentions catback non resonated ingen long tubes and berk test pipes n uprev tuned

Updates?

Yea whats going on??? This thread was started 20 days ago. I hope this is a problem with the owner of the Z and not the shop seeing is I plan on getting my Test Pipes installed and UpReved tuned by Performance MotorSports in the very near future.

My car made 340hp and 290lb of torque on a dynapack after my uprev tune. it was pretty much 10hp and 5lbs across the entire curve. My A/F ratio was way rich though and they attributed my gains to that. I also went from 20-21ish mpg to 24-26.

This was all on a Dynapack and with the mods listed below so take that as you will :)

All you guys posting numbers should post your baseline numbers as well and whether these are corrected to some standard for comparison. I actually wrote an article about SAE correction this after taking my car to a dyno dynamics dyno, which you can read here.

Beyond whether they are comparable from pull to pull on the same dyno, we all understand that dynos read differently depending on how they load the car measure the torque at the wheels. A car that climbs from 260-300 (+40 hp, a gain of 15%) on a less optimistic dyno will have made more gains than one that went from 280-320 (+40 hp, a gain of a gain of 14%) on a more optimistic dyno. Likely if you lined the two up on the same dyno, the power would be nearly identical (within that 1% of each other). Dyno results only make sense when put into context. We can high five each other all day about some pull, but without context, that pull won't mean as much.

Lets see, baseline was 296.4whp on a dynojet with nothing but test pipes

Latest Past with LTH, 2.5" plumbing, tune, K&N drop in
327whp and 251tq.

Overall torque didn't really increase before and after tune but I now had a fatter torque curve through the whole power band especially mid range. I have the dyno sheet somewhere.

Dang... good gains with that tune!
