Got my car UpREV tuned ALL STOCK no mods

[Supergyi]

#1 Surprisingly the rear mufflers on the M45 are a chambered low restriction muffler and are nearly straight through design.

Are the mufflers for the M35 designed the same way as well?

I don't know I've never looked. I do know that they are different for the M35.

You can tell pretty easily by shining a flashlight up in there, but then again???

I did just that. From what I could see, they are like the M45 mufflers, straight flow thru mufflers. Great! Now I can concentrate just on improving the flow at the y-split just before the resonators.

Hugedude,

Ever race another G37 after your uprev?

Hey Ken,
Good to hear from you.
how are you been?
how is your new truck?
it's been really boring here without you.

I have a question...

The OP has an M45. His HP was 280 at the wheels. The M45 is 335HP at the crank. We lose 55hp? That sounds a little high. I can understand 20hp or so, but 55hp?

Also, do I have to go to a tuner? Can't I just install Osiris Standard, take a 'snapshot' of my ECU and send the files to them. They then edit whatever needs to be edited and send them back to me and I flash my ECU. Or am I not understanding their site correctly?

[dvan]

From what I understand, 280HP at thh wheels is about right for the M45. The M45 is acutally rated at 325HP at the crank based on the revised SAE standards set a few years ago. Also, some dynos are more conservative then others, i believe one dyno done by another member with an M45 said he only had 230HP at the wheels lol.

[Ilya]

Wow...so my M35 is probaby like 240 lol.

thats a good question. if i were you id contact an Uprev tuner near you and they can give you a better answer to your question.
i located an Uprev dealer in New york for you. give em' a call and they may be able to answer all of your questions.

Baseline dyno on stock M35.

Hey Hugedude33,

Just checking in to see how is your car running. Base on all dyno graphs, you should be the fastet M here.
got any 1/4 numbers?

i dont know about that, here's ken's dyno's and keep in mind he's at diff. altitude and has diff. temps but his no.'s were higher if you're looking for big numbers.
post5254322.html#p5254322

And here's my dyno "number's" which are lower because of the dyno i used but if you do a calculation of the highest percentage difference of 15% instead of the 12% i used on my thread post5461794.html#p5461794 my no.'s would be 301 Hp and 336 TQ.

So fastest is kinda hard to say, also the mods done to each car are all diff. I am not 100% positive but i think Ken has the fastest 1/4 mile of 13.5 (or something with in that range) and is the "fastest" time to ever be trapped and posted up here on NICO.

[dvan]

Ken ran a 13.7 @ 101.4 MPH. He said he ran out of gear on the top end during his run, im assuming that means he topped out 3rd gear and didnt change into 4th even though he had a few seconds left to do it (i.e. higher trap speed)

[M4T5]

It's cool what mods Ken did to achieve this 1/4mi run. Unfortunately, most of all the mods he performed, are all custom made. None of which anyone could actually go out and purchase as a bolt on performance part.
The only mod that all of us could get done that Ken had done to his M45 is the UpRev tuning & Transgo kit.

His M45 mods that I'm aware of:

-Throttle body by-pass
-His CAI kit was custom made.
-UpRev tuning
-Long-tube headers designed for the Titan's were used, but not without some alterations to allow them to fit.
-Exhaust system was all custom fabbed. Used two high flow cats, exhaust pipe anti-vibration/ flexible connectors, custom exhaust piping from the there on out to the mufflers, including X-pipe cross over section then to OEM mufflers or possibly my Element 114 mufflers I sold him.
-He also had the Transgo kit: SK®RE4R01A in the transmission (I guess we could all purchase and install this mod as a bolt-on kit).
Good work Ken! Sad to see you leave the scene, but I hear you still have the M45. He hasnt sold it quite yet, but is in the process of still parting with it.
I guess it would be easier to just install a NO2 kit and get it done! That's honestly the easiest and cheapest mod to be performed without sacrificing the OEM parts.
Would be nice to see a 1/4 mi run with a 75-100 shot sprayed run. 100 shot would more than likely be the most you should toss at it in my opinion.

Perform these mods with no loss of OEM parts or reassembly:

-CAI kit (optional)
-Exhaust (mid pipe section replacement & muffler section replacement) Stillen is your highest quality bet. (Bolt-on kit)
-NO2 kit
-UpRev tuning (NA 91-93 octane high performance tune, NO2 tune, Valet tune, Kill switch mode, and OEM tune)
-Transgo kit (optional, due to difficulty of reinstalling back to OEM)

Then, let her rip down the track!!

Sounds cool!! Wish my M45 wasnt my wife's daily commuter!! She wouldnt go for all that done or spent on it.

[g1313]

question the Transgo kit whats the cost looking like and what should i look forward too?

[EniGmA1987]

He also had a G37s rear differential on his car, which is now in my car That was a direct bolt on as well for my M35, but for his M45 he also needed G37 rear axles because of the slightly different bolt sizes. Anyway, the rear diff mod Ken had helps considerably with the car picking up off the line

[hugedude33]

Well after having the UpRev for 6 months I've gotten use to the extra hp so now I'm ready for some other mods like a new exhaust. My only complaint is the lowered MGP when I have it in to tuned mode so in regular everyday driving conditions I use the standard mode (I live in Philly so I do A LOT of city driving). I was just wondering how much HP gains i will see with a new exhaust. By no means do I want a loud exhaust. I want a deep low growl. what do u guys recommend

[dvan]

Deep growl thats not loud at idle or highway cruising, Element 114

[mexillis]

i finally heard the stillen in person not too long ago and it's pretty quiet. I would think any type of exhaust you get will gain you about 10hp or so i know someone who has the element exhaust and a CAI and he gained 27/22.

[hugedude33]

I'm up in the air between the element 114 or the HKS. R/T Tuning said the HKS is a better exhaust but I've never heard what it sounds like on a M. I also been hearing mixed views about aftermarket CAI's. Which one is safe for the M's and would enhance the performance.

[mexillis]

On fresh alloy there's a guy selling his axle back HKS if your interested in it look for Br1ank in the M section of the forum.

[EniGmA1987]

hugedude33, if you put an intake and exhaust on the M, then get it tuned you will see performance gains. If you dont get it tuned afterward, you can actually see a small decrease in HP. So if you are going to R/T Tuning to get your car UpReved, then put your mods on BEFORE you go get tuned, or else you will need to get re-tuned afterward again for max performance.

looks like he sold it..

My car is already UpRev'd I wanted to see how much HP and TQ I would gain with everything being stock. The tuner only spent an hour worth of dyno time to tune the car. usually it takes 2hrs but he didnt want to go crazy with the tuning knowing I was gonna add mods later. Cause like you said, he's gonna have to re-tune again after the mods. Right now I'm just looking for the best exhaust and CAI for my car before going back to get it re-tuned. I came into some money so this is the right time to do it.

[hugedude33]

Hopefully like Mexillis I can gain a total of 30/30 on my HP and TQ. Just food for thought, that will bring the total HP to 365. A V8 with 365hp is not good on gas but that comes with the territory. You gotta sacrifice something for all that power...lol. unless you find a super-tuner like Mexillis who gained all that power and get better MPG

Keep us posted on what setup you go with. I am still trying to find a board member that has done dynos before and after with the injen. On my previous Infiniti & Nissan cars the cold air intakes were not the best for my 1/4 mile times so curious if the M45 is going to be any different.

[EniGmA1987]

Normal UpRev tunes get more power and better gas milage. Everyone I have asked about it and people who have the tune say that. So if you don't have as good of mpg, then something is not tuned properly. The tuning makes the car run more efficiently, thus you should get better mpg.

True. However, with the WOT changes and better hp/tq, people tend to put their foot into it more.

[hugedude33]

[/quote]True. However, with the WOT changes and better hp/tq, people tend to put their foot into it more. [/quote]

Exactly, in normal driving situations I really dont see a difference but with the extra horses you cant help but to have a heavy foot. When you pushing them RPM's up to 6600, you're burning gas.
