Seems like its the week of the supercharger here at Z1. Finished up a Vortech with some dyno tuning yesterday and made some pretty nice numbers, 375whp & 316wtq with an 11.5/1 average AF and pulling 1 degree of timing per lb of boost.

Today we finished up the install on an HKS and I have to say the mechanics love the detail that went into this kit. The only thing that I question is the fuel line that actually runs in through the throttle body. Seems like it could create some idle issues due to turbulance. Anyway, on with the pics

 

any numbers on the HKS? Interested to see if this one holds together.

 

Has not been on the dyno yet, but I will post them as soon as it does.

 

THose are some nice numbers on the Vortech. Did you install the 9 pound pulley? How many dyno pulls did it take to get that number?

 

Nope, stock pulley. It took about 12 runs to get the A/F right. The R4 software is very sensitive to changes so the cell values require some fine tuning to get a nice curve.

 

how loud is this hks s/c compared to the vortech? also did you notice a big performance difference between the vortech and HKS

 

the crawford plenum works with HKS.. i had wondered about it given the placement of additional fuel injectors.. by any chance does the crawford strut bar fit?

 

oh man...I cant wait to pick up the car. I'm glad you guys are taking pictures, they look great. A/F is only thing to worry about now...

 

those numbers with the stock 3.33 pulley on the vortech are VERY good...car must be aggressively tuned up top. Great job!

 

Also interested in sound differences.

 

I was told right from HKS that you CAN NOT run a plenum with this kit due to the FCON S and not codes to tune it

 

that was my understanding also.. i had contacted the shop here in Japan and they made it point to tell me that their kit was designed for stock Zs.. the pics and hopefully an upcoming dyno / AF chart will prove this wrong..

 

I dont know about you but I cant wait to see the chart.

 

Lorca, can you post sound clips if you have any, I'm sure theres alot of people that would like to know what these rotrex s/c sound like

 

Lorca, the HKS looks better on the car than it did in the back of it Monday!!! Check you PM, gotta ask you something.

werd, i'd like to hear as well

 

will have sound clip up soon, been busy setting up the car as far as gauges and stuff, i'll try and do a video clip also.
