imho it's not all it's cracked up to be, yeah the dyno numbers look impressive but the lack of responsiveness is underwhelming to me. Riding the 'boost wave of torque/power' is certainly fun but that's not what I enjoy out of a car and certainly not what I would buy a Porsche for (despite the 930's reputation). If I ever own a turbo car I probably won't do more than a catback exhaust, which on some cars opens up a noticeable amount of power. |

That wasn't even the end of it as just by putting in a cat delete, bigger injectors, and an e85 tune the tuner quoted it as making 250chp and over 300ctq now if a 80hp and 130tq bump from very simple bolt ons and tune aren't impressive I don't know what you will think is.

I doubt how rewarding and fun it is to drive around a corner when you've got monster lag to get back to maximum power. |

If it's the stock turbo, there's no more lag with an aggressive tune than there was when everything was 100% stock. In fact, there may be less. There may be more perception of lag simply because running more boost results in higher peak power, but there's no reason running more pressure from the same compressor would somehow result in more lag.

There's no lag to the original boost/power levels, but you've likely upgraded the grip available as well which means that no-lag to stock boost/power is irrelevant, it's now the lag to the increased power that's of concern. It takes longer to spool to the new maximum boost than the old maximum boost, you can't break the laws of physics no matter how good the tune is. Edit: A different driving style makes this not a problem, early back to the gas, left foot braking while still on the gas to keep the boost up, whatever, I just don't really like it. Some do, that's fine, but I bought into the hype of 'just crank up the boost, it's great!' until I tried to drive fast with a car tuned like that. I just didn't really like it and I think it's worth asking when someone starts beating that drum. It's one of the reasons I'm very happy with my FR-S.

I actually think it equates very well to a motor like the fa20 where all the power is at redline. Rather than feeling the power build as you push to the limiter you feel it build in the mid range just quickly and then it eventually dies off up top (downside of a small fast spooling turbo). At least in my driving it was felt like a similar sensation especially with slightly bigger turbo like in my friends sti. The longer amount of lag allowed the torque to build up in a natural and smooth way just like a high sprung NA motor just earlier on in the power band.

What you wrote rings true to my ears. Unfortunately, I still feel the car is lacking, just a tad...I'm not sure if a header/tune will get it where I'd like it to be. The only way to find out is to go for it. I should go test drive a MY17/18 first.

For example, for this same pricing, you can get a c5z06. In general, it is cheap to maintain. However, compared to a BRZ, the amount of oil used, clutch reservoir maintenance and 3x more expensive tires make the running costs far exceed the BRZ. Also, while I don't have direct experience with the Cayman, I am going to assume the gearing per gear is very wide. This just means the experience you are going to get on the street is going to be very different. All the updated power you aren't really going to be able to use.... or be able to use legally for long. This is something you have to do beyond the honeymoon-phase to understand what the difference really means. Good luck in your quest. Quote:

I'd be curious to see the dyno curves overlaid between the 718 and 981. I would imagine the difference in low and mid range torque would be substantial. Whether or not you care for the aural aspects of the modern turbo 4's you can't deny the improvement in acceleration capability. Lap time magazine comparisons really illustrate the difference.
Lighting Lap: 2014 Cayman S 3:02.6 2917 Cayman S 2:58.3 2017 Honda Civic Si 3:14.6 2017 BRZ 3:19.7 Tuning just increases the disparity if you are willing to roll the dice. I have an APR tune on my wife's TTS and the car runs 0-60 in 3.8 seconds on a V box and will pull bus lengths on my supercharged FRS. Honestly I'd love to have the power delivery from my Audi 2.0l available in the Scion.
