1970 Ginetta G15

Yep I'd say that's well triangulated!

You have tested that the cage fits into the shell through the doors haven't you?

My lad surprised me last night with a nice gift. ...





Dropped in on my old mate RB and picked up a few of the parts for the projects.


Ported twin CD150 manifolds.











An experimental intake











Special single sidedraft manifold and a 40 DHLA





Also picked these up out of his scrap bin - See if I can find out what they are capable of.








Couple of deep groove pulleys - a separated s/h standard one and a special ultra small diameter 9000 rpm version




Got one of these to make as well.





Loads to do.

The pointy thing only just protrudes into the inlet of the radius block (bellmouth) and is much taller than the nominal required 0.25 x dia to ensure curtain area exceeds the opening diameter. There should be no change in velocity. If it provides any benefit in flow I am not entirely convinced but the proof will be seen when I will drop it onto the flow bench to evaluate it.
What cannot be evaluated on the bench is if there is any benefit in way that the airflow is directed onto the carb bridge.

The only other thing I can think of is that it may be a way of making the carb see the intake upstream as being longer than it is - In other words the stub is only 3/4" thick but the cone may make it appear like it has a 4" trumpet. You will not see any change in flow on a bench but it may well change the torque characteristic on a dyno.

A G15 only has a couple of inches between the carb outlet and a chassis rail so no chance of nice long intake runner - One thing I do know is that the guy that raced this was very successful and a lot of the development work he was doing with Ian Carter on these engines was around improving the mid range torque.

Yep great work looking much better now

More welding and cutting of tubes.




Quick check with the cage.







Onto the next stage.











Flipped the chassis for completing the welding










Final couple of tubes cut - not strictly necessary as the assembly is super stiff and strong - and much stronger than the folded steel original.






Welding










More welding











And then some final welding








Should weigh less than what was there originally as well as being much stronger and stiffer. Need to get the body on it now to make sure I have not done anything stupid. At the same time that will also allow me to fit the additional feet onto the cage.

Shed clearout is happening - I put an old imp Engine on eBay a while back to get it from under my feet and when the buyer dropped round he looked around at what was going on and asked if I had anything else I was thinking of getting rid of...

Tomorrow he's dropping over for another collection....








I wish I could say it made a huge difference to the available space in the Sheds.

Cheers - I am quite pleased with how it turned out.

I do need to extend the garage and gain a bit more workshop space - A project I have been talking about for about 5 years.

Another long weekend - only a few left now so the plan today was to complete the welding in of the mounting tubes for the seats and two additional chassis sleeves .

Flipped the chassis and drilled and weld prepped the holes.
















And then broke out the standard conventional transformer based MIG, you know, the sort that are impossible to get decent welds with and did some welding.














And then ground them all away !








Dropped the body onto the chassis and then dropped the assembly back on the stands - Just a two man job - Everything clears fine, plenty of room on all the changes at the rear and all the body and seat mounts look sound.

Also dropped one of the far too wide Revo's on to see what the car looked like on the 4 spokes - Yep need a set of those but not quite so wide.

Body chassis connection - pretty pleased with how this is progressing now.
