STOCK PULLEY (5.75) 2.87 @ 6,800 rpm = 56,200 rpm
ATI PULLEY - (6.61) 3.33 @ 6,800 rpm = 55,700 rpm
It's roughly the same. WHP will be a little lighter than what's typical because it's an fx35 awd.

For the vq35de engine it's the standard 6.61". I can go w/different sc pulleys & cog belt pulleys when the engine is built but for now, this will be a big bump in power & I'd like to take time & get used to it & time to work out bugs before going all out. Considered a turbo or tt but the auto isn't going to allow for a big instant hit of torque + I don't care for the heat.
Don't know if my kinetix v-plenum will hold on for now, but got that, kinetix hfc's, invidia de & lots of weight removal. My goal is to build the fastest fx35 1/4 mile time recorded. Not that important, but gotta have a goal. Here's a thread I started on an fx site mostly regarding my wire tuck - https://www.infinitiscene.com/thread...-redux.230572/
That v7 you have sounds pretty serious.

That'll potentially be an issue. It's good that a % of power is distributed away from the rear for multiple reasons but, as you wrote, the trans will take all the shock. It does allow for reducing wheel width & weight as weight is an issue, not traction. What I run at the track, I can duplicate on the street.
Apparently, the biggest issue is slipping per others & IPT. Hoping the stocker will hold low 4's for awhile. When engine gets built so will trans. For now, the transgo sk is the only change I've made.

Not sure what u mean by xxx but always good to hear from the record holder.
Been reading https://my350z.com/forum/forced-indu...stions-78.html and it's interesting reading through years of vortech experience all in one shot. Invaluable info.

Anyone with the knowledge and willingness to share please do. I could use it. I'm getting ready to buy everything I need & install it but will not moving forward until I have it all figured out. One thing will be the i.c. piping & I'll be on my own with that. The thing I'm getting hung up on is removing my crank pulley & installing the ATI. Been researching and no luck yet but I haven't scoured ati's site nor have I checked the fsm.
Is there anything special about installing a damper pulley? What's the best way to not only remove the existing crank pulley but also to install & torque the ati? Strap or chain wrench? Thanks in advance.

Bueller... Bueller... Anyone out there with knowledge & willing to share, please tell me how did you properly torque the crank bolt on whatever crank pulley you installed on whatever engine you installed it on, whenever you installed it. There's got to be someone out there that has installed their own crank pulley & torqued it properly.

Whether its 'proper' or not, this is my method:
First off I have the ATI crank pulley. This one is MUCH tighter of a squeeze than the stock one. So I get it lined up and pressed in with a rubber mallet. Making sure its in straight. Mine is so tight I couldn't hammer it in, so I make sure I have enough threads to grab the crankshaft and I pull it in using air tools. Once its in all the way I let the compressor fill back up and hit it a couple more times. I generally just stops turning after the second time. Ive done that will every crank pulley Ive had and never had an issue

I've read lots of people doing it the way you described without issue. Gonna have to keep researching. Guess I'll use a harmonic balancing install tool, lube, loc-tite & a chain wrench. If I do it improperly, I'll be the one guy who has issues, I just know it.

Thread revival.
What do you guys think a v3 SI blower can be pushed to “safely”? Going in for a tune later this week and will have the following specs:
stock crank pulley: 5.75
blower teeth: 28
jackshaft: 32
charger pulley: 2.87
According to vortech the v3 si is rated to 52KRpm. With the above setup at 6,800 it will be 56Krpm(+4k) and at my preferred raised limiter 7,200 would be 59.5K which makes me nervous.
Do the above numbers look correct, thoughts please???

Read up on oldman350z's car. I believe he's been over 60k without issue for a long time.
