Looks blue! Very cool!

semtex, how was the UD installation?

The installation wasn't too bad. Getting the stock pulley off was a bit of a pain though, because they torque the bolt from the factory really, really tight. My mechanic had to hold the starter in place with a pry bar while I loosened the stock pulley bolt with a torque wrench, and it took a lot of effort/strength to loosen that thing. It probably would have been easier if the car was on a lift vs. trying to loosen it while laying on the ground.

Anyway, I plan to do a full write-up once I get the car re-dyno'd later this week to see if there are any measureable gains. But for now, here are a few pics.

Here's the Stillen UD Pulley:

Here's how the engine looks after the stock pulley is removed:

Great shots! Looking forward to the write-up.

Wow, 5 WHP!!!!! Amazing, I'd never guess!

No time to read the pulley write-up now, will comment on it later.

Thanks for sharing semtex!

Damn man your getting some great numbers off the dyno! I am going to have to follow your mod list in hopes I can hit 350 WHP! :tup:

Yeah I'm hoping I can hit 350 after I get a tune. I think it'll be close, but I suspect I may come up a little short of 350.

Shoot man even if you hit 240WHP with a tune would be sweet. I would expect it to be more than 10 WHP increase but wouldnt be surprised if you were right tho.

Ohhhh I hope you do hit 350, lol. Ever plan on going down the 1/4?

I'd like to see how quick the car has become...

240whp? You meant 340, right?

Not exactly Z related, but . . . http://www.the370z.com/lounge-off-to...sculpture.html

Yes I meant 340 DOH!

Any updates? What's next?

At this point I'm just waiting to do a dyno tune / ECU reflash at Forged Performance. They use UpRev, so I'm waiting for UpRev to complete their 370Z development.

He's waiting to trade the car in on a new Nismo - the true sports car for hardcore track addicts.
