1. Turned the engine on and you can tell that it isn't "stock". I was surprised that the car wasn't OVERLY loud. Especially while I am running the GTM Resonated Test Pipes and Invidia Exhaust. So yeah, it's not that loud during ignition. But still it sounds great!

2. I took it out of the shipping yards and onto the streets with no issues. Already turned some heads but probably for different reasons (yellow paint?) I took it easy on the streets as I didn't want to get pulled over right when I got the car... it was very responsive.

3. Getting onto the highway, I floored it to see how quickly it accelerates... it was fast. In fact, it was so fast that I didn't know I was going past 100 already in just a matter of seconds. I didn't gun it for too long though... but yeah, it's fast. And you can hear the bypass valve clearly =)

4. GTM also installed my multiguage setup. It's pretty cool. I just don't know how to use it. And by that, I mean the little controller that is attached to it. Plus I still have to install an additional sensor. I'll get into it more when I get off work...

5. Upon arrival to my home here in Hawaii, I opened the hood to see the installation. Looks super clean and appears to only have a CAI (Like most photos). Stealthy look as usual but the sound of the car is what amazes people. I can see the motor mounts on the bottom and they look great. Sadly, normal people won't know they are there unless they know what they are looking for.
The intercooler looks awesome. You can see it from far away too. It's not excessively large but just enough to cover the entire gap of the front end. And since it is behind the "fins", it still gives it that stealthy look but all that power behind it.

So yeah, my first impressions. All 30 minutes with the car before I had to goto work again =(

I'll have some videos and photos up by tonight (Hawaii time) when I get home.

Ive taken this car out for a mild spin and I have to say it is absolutely intoxicating. I could only wish there were some way to make it work/fit with the LTH... but supposedly it wont. My thought on that matter has something to do with the new motor mounts and steering knuckle.

Just driving around it doesnt feel different at all really. Still the same smooth feeling with no abrupt power surges or anything. Stop & Go or otherwise and it felt fine. I monitored the intercooler inlet and outlet temps while driving and was surpirised how well the intercooler kept the intake temps normalized. Even in stop and go traffic the temps didnt change dramatically. I also noticed the oil temps remained in the sweet spot of ~200.

When giving it some gas, I would smoothly accelerate... quite quickly might I add. I did no 1st gear pulls or any crazy shifting out of respect of the owner, but I will say that from 2nd to 3rd you will spin uncontrolably if you have anything less than sticky 305's in the back. Thankfully, he has hankook ventus evo V12's all around and 305's in the rear, which gave plenty of bite. There was still spin, but it was very manageable.

All in all, I love his car. Im seriously debating selling my bike in favor of modding my car more. I love riding my bike... but realistically I dont do it too often. My car on the otherhand, is a DD, and I love it. But its not SCd!
