PM'd, I don't wanna derail this thread any more than I already have

Zultimate

Please PM me with the same info.

oh snap!

kannibul

lol - I'm in Tulsa...well, damn near - I should get a discount.

Chris@FsP

We're taking pre-orders now

Shameless plug! *lol* If I didn't know that you were the 'best in the midwest' I would probably call you out for it... But, the guys can't go wrong having you do the install.

RCZ

Hey, having never owned a supercharged car before, I'm curious. How much parasitic drag does the SC hardware put on the revving speed of the motor? In other words, does it have a noticeable negative impact on the speed of the revs or not really?

If you're worried about rev speed, you could change your diff gearing with these: Central 20 3.9 Gears

RCZ

ummm how does shorter gearing affect my revving speed again? I don't believe that applies to the question.... in fact you seem to have completely ignored the question and answered some other question based on an assumption you made. Thanks anyway though.

My question was more about RPM drops and free revving speed...anyone?

Chris@FsP

I've driven a 350Z with a Vortech blower, and didn't notice any difference in 'rev-a-bility' ™. Of course the one I drove had an aftermarket clutch/fly, so...

DannyGT

Which is what I was going to say to RCZ...I doubt much would be lost but either way with the power we make we might as well start looking towards a nice street/track setup for clutch/flywheel which should speed up the overall rev's after the SC install.

That is an interesting question and one that I don't think has ever really been tested beyond the calibrated seat of the pants tests. Personally, I've not noticed a difference that I could actually feel.

Here are some pictures of the production cast aluminum manifolds and some of the support brackets making their way into the machine shop. Also you can see some of the billet aluminum end tanks in the mill going through their first op.

The machining of the intake manifold is an 8 operation process. The mounting bracket is a piece of billet aluminum which is waterjet cut then comes back to the machine shop for drilling and tapping and finishing. The end tanks are also billet aluminum and are only a two operation process but the machine marks left behind in the aluminum are beautiful and really make the intercooler pop!

You won't notice an impact on the quickness of revving through the power band. What you will notice is that the RPMs jump from mid-range to redline VERY quickly. Lower down in the RPM range, you won't experience lag, but you will feel a very slight 'bog'. At least, this was my experience with the Vortech blower. With the roots type blowers, I notice zero lag and no real difference in RPM building even up top.

Easy to make a roots blower drop off high also - just push it beyond its efficiency range. I pushed the old M112 to its limits and beyond years ago before swapping to a Kenne Bell.

stormcrow

The only experience I have with the roots is with the Stillen SC kit on the Pathfinder. I don't think the blower was out of its efficiency range up top, but I could be wrong. The Pathfinder didn't have a high RPM redline, so it shifted around 6k. I just didn't notice it jetting the RPMs from 4500-6000 nearly as quickly as the Vortech blower did on my G35. Maybe the TVS was running out of steam up there? :shrugs:
