I wouldn't put it past misprint, which is why i only claimed that i thought i read they were those sizes.

I thought it was odd though that they left the staggered for a non-staggered setup

New set of Nitto NT05 tires showed up today! 275/35/18 front 285/35/18 rear. We'll see how the less staggered setup does August 1st & 2nd. We'll also find out if running a wider and stickier tire up front will uncover any more weaknesses with the car. Hopefully not, fingers crossed. My biggest concern to be quite honest is the SPC Camber arms either hitting the top of the wheel wells and/or not holding the alignment settings under hard load.

Mike, you should be able to check the wheel well for impact marks when you swap tires before this event, correct? Keep us posted!

Oh yeah, I will probably check for it even sooner than that.

Sure

Scott@FontanaNissan · 07-08-2009, 12:01 PM

Of course you would let me....wouldn't ya???

I would.

Just ordered an Unorthodox Racing stock diameter crank pulley! According to them, this will shed 7 lbs. of rotating mass off of the front of the car resulting in quicker revs, better throttle response, and more freed up horsepower. They are also claiming gains of 10-14 horsepower, but I am assuming that is at the crank, not at the wheels. We'll find out soon enough!

PM me for pricing and availability!

10-14 hp from a stock diameter pulley???

Even at the crank I'd be surprised if it made that much. I dyno'd the Stillen UD pulley at +5whp on a DynoJet. But like you said, we'll find out soon enough.

Yeah not too confident in their numbers either, but we'll see. I would expect gains to be in line with the Stillen pulley.

Except the Stillen one semtex dyno'd was underdriven, the unorthodox one isn't. Should be even less.

Not necessarily. It will depend on the weight of the Stillen vs. the weight of the Unorthodox.

But doesn't pulley diameter come into play as well? Smaller diameter = less power diverted to the auxiliary systems, right? I think that's what wstar is getting at.

Yeah it does also have effect but if its also heavier than the UR one then it will be a wash. Even if they weigh the same, I would guess that it will make 1whp difference max, or less. You will gain more from less weight than less parasitic drag. Like I said, we'll see once I put the UR pulley on my car. I personally prefer to use a stock diameter pulley to maintain factory accessory outputs from the alternator, power steering, etc.
