Tornado TS40 #875

Scott, is that insulation on your bulkhead panel? If so could you tell us what you are using? I have Dynamat around the tub and footwell but don't want to expose the material to the engine heat on that panel as I am sure the rubber backing will melt into a horrible black goo.

Keep up the great work

Hey Brian,

Nothing on the rear bulkhead yet.

It has only been cleaned up with a red scotchbrite pad and isopropyl alcohol.

The Tornado supplied sound proofing, that is included in the Deluxe Component Package, will be utilised.

Cheers,

Not much this evening, just drilled the left front wheel arch.

Excellent progress Scott. I'm impressed!

[Bill D]

WOW!! That is going to be spectacular!

[Scott Calabro]

Well thank you Charlie. I'm fortunate to be working with a product that is mature and well developed so it is easy to build.

Bill that is quite a compliment coming from someone who has built such a good looking car, thanks!

Not much this weekend I kind of took it easy.

Installed the rod type shift linkage.

Installed the pedals and cylinders, gas pedal and mocked up the cable.

Installed the steering shaft and quick disconnect wheel boss.

Put a buddy of mine who is 6'4" in the car, he fits quite well.

Tomorrow is another day.....

Today the engine runs went very well.

My 289 developed 395hp & 355tq !

All from the "little" Holman Moody C30Z cam & 11-1 C/R, & Eddie heads.

This was with the 180 deg high rise and 600cfm holley.

The pictures show this setup on the inertia dyno.

We went on later to install the 44IDF's, and made a best of 384hp @ 6500 rpm & 375tq @ 4800 rpm.

The Webers really ran best overall, as the time from 3500 rpm to 6900 rpm was just over 1 sec faster with the Webers.

The engine shop is in Simsbury CT, THEY ARE A FANTASTIC SHOP!

Thanks to Norm, Dave & Chris!

Ok so I posted 3 videos of the engine runs on you tube.

1 with the 180 high rise and 600 holley, the other 2 with the webers. here is the 385 HP weber run to 7000RPM.

Nice goin Scott, would have been interesting to "see'' a run with the 180° headers installed but dyno setup would probably prevent easy fitment. Well done!

Jac Mac

[Scott Calabro]

Thank you Jac!

I would have liked to run the 180 exh. setup also just to see if the tune up would be significantly changed.

Yes fitment on the dyno would have been a small but not insurmountable problem... time was the biggest setback.

I hogged the dyno all day!

Nice to see another Tornado thread taking shape.

Steel underpants at the ready...............

Can I ask what 'sealer' you are using between aluminum panels & chassis?

Advise from fellow Brits is to alter the seatbelt fixing points [below window aperture] to accommodate 4 point harness etc before getting to far down the build route with Aluminum paneling since it is less trouble.

Hi Karl,

We have plenty of sealer on hand, available for purchase.

Yes, it would be easier to attach a fourth harness lug before installing the alloy panel on the rear bulkhead.

However before modifying your chassis in any way, you should seek Andy Sheldon's counsel, as he has produced hundreds of chassis.

Best regards,

S

Hi Scott,
I don’t see any reason why Andy needs consulting on a very simple mod like this, as long as they are welded in properly. Actually fitting twin harness lugs would improve the load distribution in the cross-bar in the event of an accident.

People on this forum have come up with some very sensible mods for the Tornado chassis and I will be following some of these on my build. This includes welding seat frame cross straps, so that the seat isn’t bolted a thin sheet of aluminium (not very good in an accident). To get these cars registered in the UK, SVA regulations states the following: ‘Seats are required to be secured firmly to the chassis or other obvious load bearing parts of the vehicle structure’.

It will be worth considering now how you are going to meet your local regulations.

Regards
Andy

My tornado chassis came with Four point harness mountings, as I requested them. I was having my chassis powder coated so it made sense to have them put in from the off.

I would always speak to Andy before changing the chassis in anyway as Andy has been producing these chassis for a number of years now, so knows how the loads are spread through it.

If the seat is secured to the floor, in the correct manner, then it should be OK. In the event of an accident it the mountings only hold the seat in place, not the occupant, this is done by the seat belts which are secured directly to the space frame part of the chassis.

Given the number of cars Andy has put through the SVA, I'm sure VOSA would have said something if the vehicle doesn't meet the requirements.

[Andy Green]

I don’t doubt that Andy has got vehicles through SVA, but to mount a seat to an un-reinforced aluminium skin, a material not known for its fatigue resistance is not good engineering practice.
