Well considering I showed you a video of a g putting down 325 at the wheels and it has cats and not test pipes. Easy +10 changing that out. Add 1 piece cf drive shaft, urethane motor and tranny mounts, and differential bushings, you can recover another 5-7. You are there, rather I am there. Follow my build thread if you want to see it happen in the near future.

Many z1 cars have done it too. While dynos are subjective, the guys at uprev predicted 309-311 and it did 301 with no tune, when they finished we were at 325.

Nothing misleading about what it said. The right complimenting mods with an uprev tune, done by uprev, and the right car, you can get 340 to the wheels which would put you really close to the 400 hp range.

everyone can talk the talk...I've never seen a G put down 340 with bolt ons. "Maybe this" or "maybe if I do that" doesnt count in my book. I hope you do prove me wrong as I'd love to see 340 on a G so I'll play along a watch your build thread, until then its just wishful thinking

 

I think it is possible with the extra intake side mods. Larger Intake, MAF, ported upper lower and TB. Full pulleys, cam timing, 2 piece rotors, lightweight wheels...etc There is no secret, but you need every mod on the market.

 

Im kinda with this guy. I am very skeptical about those numbers.

 

Well it depends on the dyno. The dyno is just a before/after measuring tool, so what really needs to be shown is a ~65whp gain with no forced induction and stock engine internals.

 

absolutely it is and the same dyno should be used every time. However for a the same dyno to show a 65whp with bolt ons is hard to believe.

 

There has already been a z that put down 326 with bolt on's. Look it up on the370,this was done with stock exhaust. Full exhaust would get it close. Baseline whp was about 270's I believe, so a 56whp increase is pretty close.

 

Question to those with uprev tune:

How is the difference in throttle? I think my tuner might have completed skipped the electronic throttle map, which explains why the car feels almost exactly the same despite gaining ~25whp. I still experience a throttle lag.

Just recently read about it on a thread on the370z, and I can't stop thinking about it. Even more upset that I call my tuner almost every day and he never answers.

 

Improved throttle response is the most noticeable aspect of my tune.

 

well..shucks! Guess I need to visit my tuner.

I'm sure that something is not right if my throttle behaves the same way.

 

Throttle sensitivity is very noticeable. This can be done without spending 200+ on a dyno. I just had mine done again tuning for my latest mods.

 

My throttle is like instant, or pretty damn close the second I hit it the car takes off
the drivability is the biggest change. I remember when I first did my NA coupe tune I was at 297 WHP without the tune, after tune I was 298 WHP but the midrange and throttle response was COMPLETELY different. The car really pulled in the midrange just pushes you into the seat, My sedan is the same way no just feels like more of a push than my coupe tho :/
Different tuner.

 

I'm on the fence about the tune because of warranty reasons but it's my understanding these cars are pretty reliable when staying NA. I also heard infiniti dealers really frown upon tunes but I guess that only matters if you have a problem.

 

I might have to ask my tuner to just copy paste the table from here:

Smooth Throttle for UpRev - Nissan 370Z Forum

If not, I'm pretty sure they will try to charge me. I didn't even get a valet map...

 

Exactly. My tune provided less than 15whp, but it completely changed the car. Throttle is instant like you said and the mid range is so smooth and powerful I surprise myself sometimes on the highway.
