Engine, Gearbox, GT40, Interior

While I haven’t done much (mostly due to Christmas) I’ve done a lot more planning and a bit of ordering.

I’ve ordered my engine to gearbox adapter (I’ll have one spare for sale, leave a comment if interested).
I also found out the rear wheel centre line and measured things up, I think the engine will need to go forwards 3cm from its current position.

I’m not going to bother with the flywheel and clutch yet, no point. I’ll get them sorted when I’m nearer to being able to get it mobile!

The 1UZ-FE oil filter sticks out the side and would end up in the side of the chassis, I need an adapter to mount it elsewhere. It’d also be nice to have an oil cooler. Thankfully the oil filter is an assembly that bolts onto the side of the engine, there is a nice simple fitting on the side of the oil pump that can take a plate and some oil-lines.
So to get the dimensions I took off the filter assembly (alone with oil->water cooler) and stuck it along with a ruler onto my scanner. Then scan it, copy the picture into CAD and trace it. That was the easy bit.
The tricky bit was working out what fittings I could fit. They need to be as large as possible (to prevent restrictions) yet the fittings are rather close together. The issue being not the threads but the size of the nuts to do them up! I eventually finished on M16x1.5 aka M16 fine. I’ll probably go for a M16 to AN-10 fitting.

As an update to one of my previous posts I’ve found out the tacho can be adapted via dip switches to be altered to various modes, no adapter required! 🙂

ABS TCS DSC and EBD

Uncategorized

I had a nice idea of fitting a Bosch ABS5.7 system into the GT40. I’ve given up on it. I just don’t have the access to the system I need to make the changes I’ll need and its just too safety critical to bodge it. Without getting too technical essentially I’d need to ‘tell’ it about the type of brake calipers as well as how fast it can slow down (under ideal conditions). That’s just for the ABS/EBD. For TCS and DSC I’d need that plus it to integrate it with the ECU/PCM as well as cornering ability to steering angle, roll rates and a whole load else.

I plan instead to add the bits that the system would need, ie the sensors and route the rear brake lines individually (normally it would be a single line to the rear and then a splitter). Then if at some point in the future I can justifiably afford a Bosch M4 I won’t need to dismantle and rebuild half the car to get it in!

That then still gives me the option of tracking wheel speeds, steering angle, G, roll and yaw.
