As far as hp draw from the blower, Vortech features the most efficient superchargers in the industry, so due to the efficiency and design of the Vortech centrifugal compressor it will certainly be far less than any other Supercharger...no matter which brand you choose!

Great job Brian! looks good..

@ Brian: But, that's not what I asked if Vortech is more efficient than other supercharges. I was asking how much power will it draw from the engine to produce that much volume of air. I'm sure these tests are done at your facility, but if you don't want to divulge the info, I can understand.

That supercharger sounds insane! Very nice work

[Fritostud]

[Gotthat02fire]

Hello everyone,
For those who don't know me, I am cody chapman from Wickedhp las vegas. I think Brian hit on most of the details of our current combination. If you guys have any other questions please feel free to ask, as i appreciate all input so we can always improve our product. I would also like to let everybody know that our current goal has not been met yet. With in 3 weeks we will have 1000rwhp on 91 octane pump fuel and it will be streetable. We have already done startup, idle and driveability on this combo. Stay tuned for updates as, I will be efficient as possible with my replies.

P.S.-I also have and will be posting our other available packages within a couple of days.

Thanks, cody chapman

How about something along these lines for the V6?? We're dying for some FI!

Yes, that looks like a tiny pulley on the blower - how much boost?

Did you strengthen the stock LS3 block in any way ?

Also, I will ask you guys the same question as everyone else - what upgrades did you make to the trans/driveshaft/diff and axles? We are all trying to see what really works.

Thanks.

Hello everyone,
Here is some answers for you guys, hope this helps.

1)The smoke from under the hood at the end of the run comes from the breather system that is not finished yet. The cause is when you let off the throttle after a hard run the rings will unseal for a split second causing blowby until they recover from the major change in cylinder pressure. We have a solution for this, just have to finish it.

2)I believe the boost is in the 14-16 psi range right now, but i have'nt checked it since we changed pulleys. I want to tune it all the way to 7500rpm first. The 896 run is only at 6000rpm. The 850hp/710tq run was with 12 psi. This engine is extremely efficient so it takes less boost to achieve a big number.

3)The fuel system is a custom system we are working on utilizing the stock pump system as a balance system. We use an eliminator pump for the engine. We are using the eliminator because we will most likely put 250 worth of nitrous on our car when we finished with everything else.

4)The block is a stock ls3 with some internal modifications that we do in house. The drivetrain is all bone stock right now as i wanted to find some limits for our own knowledge. So far with hard street driving and some 7500rpm wot launches in 2nd gear off the clutch we have had no problems. I will let you know when and how we find the limits. For now good job gm.

thanks for the more detailed info. That makes your power output even more impressive that it is utilizing the base ls3 parts.

[michael's maro]

Great job guy's. I want some

[speedster]

Thanks for the response Wicked...

Looks like you are coming up with a great combination.

Hope it all holds together and if you do pop something in the drivetrain, please post or PM.

Thanks Again and great numbers !!!
