I thought this was about the "redline" Q60. the price point between the NA Q50 and Q60 is HUGE...but the Q60 is turbo and has 400hp and a crappy transmission that can't really handle the power anyway

[@SpeedCultureStudios]

I think you have some incorrect information. This particular video is about the 3.7L q50 made between 2014 and 2015. The 2016+ Q50 and Q60 are twin turbo cars, yes, and are rated at 300hp. The Red Sport Q50 and Q60 are rated at 400hp. The transmission these cars is actually pretty good and has handled well over 600hp without much trouble. The transmission in the 2014-2015 Q doesn't do well over 400 hp, but its the torque that is the problem more than the hp.

[@acm_1028]

I'm glad you made this video. I regret getting test pipes and tune, I "built" most of my exhaust myself so it was cheap. On the dyno my car did 302.5hp and 240.82tq stock, after tune did 315.37 and 257.58. So a gain of 12.87hp and 16.76tq. Not much at all but the graph looks a lot cleaner. Despite the small gains, it's never been as fast as it was stock. I ran a 4.76 0-60 before the tune and haven't seen less than a 4.8 since. I'm not even sure of what to think of the numbers anymore, I'm just tired of the VQ37. Also it doesn't help that my gas mileage is 13.6 average. My original goal was to shoot flames but then I started growing up and being scared of exhaust tickets.

[@SpeedCultureStudios]

If it makes you feel better, 0-60 is not really a good indicator of performance improvement after a tune on the vq37. It’s not a stop light to stop light car because it’s not all that torquey. The gains are in those higher rpm and higher mph points. The improvements seem to come more on the 1/8 to 1/4 mile runs where you’re getting to use that peak power.

[@SuLu_XD]

I had a VQ37 for about 10 years and recently sold it and picked up a B58. The truth is just that the mileage sucks and the car isn't even *that* fun for the mpg. I can totally understand living with 10-15mpg in a Hellcat or Corvette, but not in something like this. My total average after 10 years was 17.6 mpg and that was driving like a grandma for the last 7 after I stopped going crazy with the car. The new B58 gets 20mpg+ when I drive like a madman and has so much more power. I'll always have a soft spot for Gs and Qs but if you're looking for performance, they just aren't it anymore!

Thanks bro, slowly building my AWD 3.0t I’ve been thinking that myself from having a 350z before it makes more sense to work towards handling and maintaining the tightness in the vehicle or even improving it. I know this 3.0 has more power potential but really getting it over 350hp to the wheels isn’t hard at all with the 3.0 platform so after getting the heat exchanger for it from z1 I’m thinking I should do brakes or suspension from z1

If you’re truly into cars you already know this isn’t a forgiving hobby. We have 100k cars competing in events paying out less than 10k every weekend and in my opinion the vq37vhr has way more potential than the vr30tt but that’s for another discussion.

[@sleepy_ipl]

Test pipes will work with short tube headers. However your 2015 q50 already has the updated exhaust manifolds from factory compared to the previous year models. Going short tube headers is not worth it and you won't gain much power. Not to mention, header installation on the vq37 isn't a simple job like installing test pipes or cat-back exhaust. It can easily be a 5+ hour job if you've never done it before. Drivers side can be a nightmare. It's tight space to work in. Also the invidia exhaust is the worst performing exhaust you can buy for the 3.7. The inner diameter of the piping is narrow. Every other aftermarket exhaust for the 3.7 on the market is 2.5" piping minimum. The invidia is like 2.3"

[@_rbswifty]

I agree that it is very costly to get more hp out of an N/A q50 that is almost pretty much maxed out from factory. Honestly the only things that will add a little power are the mods you mentioned test pipes/headers, catback, and drop in filters as the stock air intake system is actually pretty good already. You definitely need a tune after all these mods as they bring in a lot more airflow and you wouldn’t want it to be running lean and possibly blow up. That being said I couldn’t be happier with the mods I did 7 years ago. ARK catback, motor dyne test pipes, k&n drop in filters, ported upper and lower intake plenums, and tune. I just never get tired of downshifting and revving it out to redline. Have been tuned and raced many many many times for over 70k miles.
