600whp Vortech

Just a good old V2 Sc trim 
I wish it could be better...but that's just the way it is with the centrifugal SC...but it had a nice linear powerband, kind of like a NA car...
Unfortunately I didn't video the dyno...I'll try and have a friend video the car at the next meet and rev the engine so you guys have an idea what the mondo bypass valve sounds like...
I'll have some more pics of the piping work I did on the vortech...but here's some pics from meets (thanks, WAIZZ)
My tuner said I was at 80% with the ID 1000cc...I probably have to upgrade the injectors for E85, but the Walbro 400 pump should hold up...and I don't doubt I'm right at the limit of the 928....
Thanks!
Lol...I've done mutliple fail trips to the tuner because of my fuel issues...I was almost ready to give up and be content revving to 6krpm...but when I finally figured out the fuel issues it was like a dam broke and I had fuel galore...and finally maximize my tune
Well...I've been meaning to take her to the drag strip...but I got no drag skills and will be running on street tires...
Yes this is probably it for the 928...unless someone else had the guts to overspin it even more with the 2.62...I think the next threshold belongs to the YSi...
Thanks...I always re-baseline with the dynojet, to get a more comparable number...the dynapack gave me more spectacular numbers and a better torque curve...
So do I...
Yes, 91 with water/meth up top for protection...I have no idea what my tuner set timing wise for the car, but she runs great....
No way! After all the rental car money I paid when I blew my stock block, and knowing how finicky FI cars can be, my Z is now a garage queen...she deserves her title after 85,000 miles of daily driver duty...besides, do you know how awful the mileage is on 1000cc injectors...

wow, great numbers man, I bet shes a blast to drive. In for videos and final pictures.I'll have some more pics of the piping work I did on the vortech...but here's some pics from meets (thanks, WAIZZ)

I go by calculating what i put in the tank verses mileage.
This is awesome. It's probably going to take a custom 8 rib setup or even maybe that wicked cog belt setup that someone had built for their vortech floating around here. That would be nasty.
Based on that a/f it looks like you lost out on fuel right at the end. Was that the first dyno before the 400 walbro? Those injectors will outflow that walbro 400 at the 40psi fuel pressure. As fuel pressure rises you loose flow from that pump so it's hard to say which would go first, fuel pump or injectors. The way it looks you will need more than that walbro 400 to support e85 at that s/c power level. It's unfortunate but volume is volume.
Nothing but dyno time lost to try it though!

Well done! I am happy to see someone actually spinning the 928 impeller to the range it was designed for! My car felt great at the low 400whp range when I was helping my father-in-law (Carl) test this impeller. I can only imagine how your car feels at 600whp! I would love to see videos!
By the way, have you shared this with Carl?

Oh, that dyno time can start adding up cost wise, particularly if it ends up being a fail...
Oh man...the thought of having to install the dual pump
...it was hard enough shoving 1 hose up the fuel tank...but you may be right about the fuel...

...it was hard enough shoving 1 hose up the fuel tank...but you may be right about the fuel...because it calculates it on IPW which is a lot smaller for a large injector to put out the same fuel.

I did mention it to Carl....I am considering having him rebuild my poor YSi, I found a place selling aftermarket YSi impellers since Vortech will not sell the parts...HMMMMMM
BTW, do you know what rpm the 928 impeller runs out of efficiency? I asked Carl this question and I didn't get a clear answer from him.

Thanks...and you may want to consider the 928 pulley, the ribs are shaped to minimize slip....I don't have any slippage and I don't need to tighten the belt like a violin...
I did need to machine the pulley to fit our setup though...
And then of course there's the Reichard Racing pulleys...
