For those too lazy to click here is the litchfield dyno:

I'd imagine with similar piping, they will likely put down similar numbers (note their dyno reads high). I signed up for updates with litchfield probably 6 months ago and haven't seen anything. I know they've been running around with it on their car for a while.

So stoked :)

You'd be shocked how much torque the vortech cars have. I got my first ride in one yesterday, shocked the hell out of me. I'm generally not a fan of centrifugals but that thing was strong down low and had major top end. But yes, it'll build boost (and torque) like a vortech.

I believe the litchfield setup has changed slightly since those pics. They're at the ring testing it at the moment and the pipework is definitely different:

I drove one after already having my AVO kit.. It's incredibly mild down low. It felt very close to the stock car. Packs a punch at higher RPM's but down low, it left a lot to be desired (For my tastes).

I can echo that. It has a little more grunt than stock, builds very linear, and around 6k you can really start to feel the boost factor and then it's time to shift. I'd need more seat time but it didn't blow me away. Very clean kit and a great reputation for reliability.

Hmm pipe work looks different to me... Though i cant wait to see finished results! They need to get a thread up here too!

Of course when you compare it to a tiny little turbo the turbo has more torque under 4-5k, but to say it has 'no torque' is incorrect. They are considerably stronger than stock across the rev range.

Awesome to see Kraftwerks developing a kit. I was wondering when/if they would pop up with the Rotrex. Very exciting!

Conveniently right as so many of us are installing Vortech's haha! Hopefully it comes out nice compared to their honda setups.

I didn't say it has "No" torque. It also has nothing to do with with a "tiny little" turbo as I've been a passenger of a FBM kit, FA20Club kit and again, the Vortech is very mild until 5-6K RPMS are reached. Yes, it is better than stock, no it does not feel strong when compared to basically almost any other of the currently offered FI kits below 6K RPMS.

It's not supposed to outperform turbos, centrifugal superchargers can't be expected to. My point was just that it make plenty more torque down low than a stock car, in response to a guy who said it made 'no torque'. That is wrong. No one was comparing it to a turbo.

Ok, fair point. I didn't mean to discredit or argue your point. I just wanted to share my experience with the Vortech kit. It was my bad for quoting you in the first place. :thumbup:

ANDDDDD....


Back on topic :D

My guess is that its the difference between prototype and production. They might not had the right bends available for the prototype and went with a straight section to test with until they could develop something more user friendly.
