Norfolk Tornado

I’m going to use a corsa c column on the gt forte is about to start building. How did you lock of the adjustable height and what did you do to extend the shaft to the steering wheel. Cheers in advance Phil
Beware if building the GT Forte that the dashboards supplied by them are different to others. The GT Forte dash is wider and the steering column is in a (slightly) different location. Enough so that if you say bought a Southern GT dash it wouldn't fit properly.

If you have bought a chassis then I'd go with their dash (I don't know if anyone elses dash is the same size).
If you bought the kit where you weld up the chassis then buy the dash *first* before finalising the column location.

Anyway, I used a Suzuki Wagon R / Agila A column on mine, it's smaller & lighter than the Corsa plus it has a magnetic clutch on it so that if you don't want assistance you're not dragging the motor round. It's also a perfect length to fit without *any* modification to the column (it means I can use the steering lock which will help for IVA).




Downside is that the steering column spline is rare (both ends) however you *can* get them.

I used a Borgeson 014925 UJ (purchased from the US) which converts the 11/16-36 to 3/4-DD along with a 9/16-36 to 3/4-DD which means I'm not messing with any welding of the column. Just need some flats milling/grinding on a 3/4" bar.

For the wheel I will use the original wheel for IVA. At a later date I can then use an adaptor to put a different wheel on.
 
Hi Phil,
Have at page 2 of my build log, as there’s some more information on how I fitted the EPAS unit. I think I used a unit with no tilt section. For the steering wheel I was able to buy a proper adapter hub, but for another build I bought an old steering wheel to cannibalise it for the splined hub portion. I have a lathe and I was able to machine up all the parts to get the system to work.

Regarding the dash comment, I surprised about the comment GT-Forte dash being wider as my dash was used to make Darren’s mould!

Wider than the SGT/GTD/Lee Dawson dash. Probably the same as Tornado.

It's more that the column location differs that is an issue.

I had the same issues with the GTForte dash. Steeringwheel position in the wrong position.
Ended up with cutting the middle gauge piece out and repositioning it more to the right.
Now my steering wheel sits straight & in the right postion.

Congratulations on the features in the magazine! The level of finish is inspiring! Are you planning on bringing it to Stoneleigh this year? I'd love to see it in the flesh
 
Andy,

I am interested in your equal length headers. I am most interested in the sound, I suspect there is not much difference in horsepower. If you listen to an original GT40, the sound is fantastic.

I have a Tornado GT40 with their exhaust headers, they are not equal length (ranging from 26" to 44").

Did I remember correctly that you tested both the original unequal length headers and your equal length headers? Please respond to me about the sound. Do you have a video of the engine at full song?

Hi Bob,
I never tested the effect of equal vs. unequal length headers, as I knew equal length headers from a design perspective would be the way to go. Having equal length headers will have an effect on the performance, but not much on acoustics. The biggest difference between the video and probably what you’re running in your ’40 is a full race long-duration cam and straight-thro pipes!
Regards,
Andy
