The ONLY one I've ever seen with the welds together like that on the charge pipe and the vac line in across from the BOV...

I swear this is my old kit!!!

It well could be. It definitely looks like it. BHS made a few changes to it, but the basic pieces are the same...

That video system is kinda cool, but for that much money I'd rather have a Chasecam or roll my own.

The Chasecam is definitely good too. I chose this system because I prefer not having to connect the recorder to the computer to download the videos. And the link to the camera is digital, so the recording resolution & quality is a bit higher.

Very nice set up

I have read a bit about the twin charge set ups so what seems to be the main issues with reliablility of these systems?
Do they required a lot of tweaking and set up to get right?

FYI, I put three other videos from the same event on YouTube:

The main issue is that the Tritec doesn't like 30+ PSI of boost...

not if you know what you are doing, the rumors of reliability started from the early days of testing...

Doesn't count if your bottom end is built.

Eventually something will give though. 300 whp at 16-18 psi of boost > 300 whp at 30-35 psi of boost.

So for the same price you could go a RMW set up or a twin charge set up putting out similar power?
Or would the twin charge cost more?

Just to be clear to everyone: this engine *does* have a "built bottom-end" (among other things). So don't think you can get similar behavior by simply tacking on a Turbo to the stock system...

I *am* going to post more details on the components as soon as I have a bit more time.

Knowing these cars as well a I do, there's no getting over 280 WHP persay with out pistons... so dood prolly has em...

35 psi for me is about 450 WHP...

However... I concur that I would rather make that at ten lbs less boost...

300 whp at 18 psi > 300 whp at 28 psi

What about 28psi on a .20 over built bottom end?
That increases displacement to a 1.8 correct??

What about over 300whp with 19psi

It's a supercharger, so it should be running the same boost, barring a pulley change.

Yea, but it doesn't make ANY power until 3500 RPM's...

Ehh, no. I think .60 over would put you at about 1.7 liters. Jan did some math and came up with the figures. I don't remember what they are. Boring out .20 though doesn't equate to a .2 liter displacement change.

yeah and the only time yer below that is in first for the most part.... especially if you know the car... and know how to drive it.... even my car with all it's low end TQ... it's best driven from 4500 to 8000

at 3500 RPMs the rotrex is makin 110 WHP give or take with the new injectors... funny thing... the turbo make 90 WHP, the difference is how it comes in... where the turbo then goes to 300 WHP by 6000 and holds till 8... the rotrex is a smoother climb maximizing it's WHP at red line.

I am not saying one is better than the other... I am saying it's two different styles of driving and performance... even my car... samething.... it's how it comes in... in a place like AZ where Kalbone is, Turbo is king... now on the a real tight 2nd gear course... I'll take the grunt of the M45 SC, TC or something comparable.

Spool RPM's aside, there's still a timelag while the turbine spools. On the track that quarter second for the boost to kick in means exiting the corner or getting passed.

Trust me I wasn't comparing a turbo to the Rotrex. For my driving style the Rotrex wouldn't work for me.

Stroker is where it's at!

So what is the spool of the rotrex like? Isnt it instantanious like the M45? Its belt driven right, so im curious...
