Actually, the AT diff is a couple of mm's thicker than the MT diffs (I'm not certain if the pumpkin's are the same). If you want to change the FD on your AT you will need to get an MT diff. Cusco offers a line of LSD's for the AT and the MT pumpkins.


To the OP I would love to have the powerband that you have . I may need to trade up to an HR soon. 320+WHP & 8000 rpm . Just to think you can easily break 340whp with some aggressive cams.


With all of my mods I dynoed at 278whp

 

They are actually swapping the pumpkins not the diffs.

 

Videos!!!!

 

Very impressive. You can get close to 350 to the wheels with proper head work and a retune. Shed some weight off the car and you'll have an absolute killer on your hands. People don't suspect Z's with that kind of bolt-on power.

 

+1

 

When you improve your car's power, your car feels like a beast roaming the streets. It's a nice feeling.

 

Wow, great thread. I just got my08 350 with a manual and would like to eventually add some more HP, though I don't think I want to go the FI route. Can't afford a blown engine.

Some awesome info and potential of the HR in this thread.

 

Thank you very much for the kind words. Car feels amazing


BTW what type of videos do you guys want to see. I constantly get requests to make some but of what? Just some drive bys? Acceration from inside the cockpit? LMK so I can make it happen...

 

Inside the cab would be nice to hear. . .

One thing that really sucks about a lot of videos people make is that they only get a few good seconds of hearing the engine when it's under load i.e. a driveby .. .when it's in the cab everything's muffled. . .everyone has a vid of their exhaust revving in the driveway. . .

I'd love for someone to mount a camera on the rear and get the exhaust tone all the time when it's under load, i'll do that in the G when i get back and post em up (not an HR )

Your car sounds amazing, I'd love to hear more of it for longer!

 

this is a hub dyno yes? I dynoed a lot less with the same mods you have and I have a 6speed.... I have reflash and everything but headers but I doubt that and different tuners can get over 20whp difference?

no?

 

The headers made a noticeable difference. Depending on how good your tune is, it can and will make a difference.

 

Some drive-bys with, preferrably, Mac10's.
Some cockpit acceleration.
The over all revving of your car.
Just wing it into one 10 hour video.

 

Some cockpit vids would be cool (especially some vids of the speedo & tach)

 

Some in car police videos would be cooler jk

 

It might be taboo on this site, but some acceleration vids next to a stock HR would be awesome and quite telling.

 

.

 

Hey A.H., whic stillen header did you get? Stainless 304, 409 or Ceramic coated 409?

 

Superflow as it says on the bottom of the dyno sheet

 

how do superflow's compare to dynojets typically? do they read higher or lower?


A.H, i know you already blew a bunch of money on testing stuff for us, but what are the chances of you going to a dynojet dyno for one more run?

 

304. You wouldn't want headers to crack and pay to replace it.
