Resurrection and development of V8 Project GT1

Will the cable retention zip-tie be replaced with some safety wire? I never trust plastic as it ages.

[mike_sekinger]

Hi Thomas,

Yes, the cable is actually a firm push fit in the machined retainer but a safety wire will be a lasting backup.

Cheers,

Flywheel and clutch pack installed.

Clutch slave mounted, but I need to create some additional clearance for the hydraulic feed and bleed lines.

Nice to see all the progress Mike. I guess completion has slipped back quite a lot from first estimate, how long before it’s all done you think?

 

lovely work BTW.

Hi Trevor,

Sadly yes.  It has taken a lot longer to sort all of the bespoke parts (flywheel, clutch slave, driveshafts, gearshift etc etc).  I have also been holding back as I will install the CNC rear uprights before mating the body.

I would expect to have the body back on and ready for the first engine start in August.

There will be some programming/tuning for the Shift ECU to get the ignition cut and downshift blip just right, but that should not take so long. 

Cheers,

Mike S

Mike,

Very few projects run to schedule and in your case I’m not surprised given the attention it’s getting, fabulous work. Finding time for an oil change runs over schedule in my house 🙂

The attention to detail and involvement is awesome.

I might be a bit old for the position but I'd love to be your apprentice.

[mike_sekinger]

Huge thanks go out to Andrä Schrörs for helping me out with the upgraded driveshafts and hub hardware.

This config has been tested hard on Andrä`s hillclimb car without any failures.  The combination of mechanical grip from soft compound tyres and LSD confirm how much punishment they can take.

Installation will wait until the CNC rear uprights are installed, so turning attention back to the body in readiness for the long awaited drop back onto the chassis.

Also made up the clutch slave bleed.  This will be braketed on the slave aperture for each of access.

[mike_sekinger]

Slave cylinder installed with calculated push-fit spacer machined by Andrä.

The slave has 12mm stroke and a max. movement on the spring of 4mm.  Will use the provision on the clutch pedal to limit the pedal movement.

What will become the clutch inspection cover once grommets are fitted for the hydraulics

[mike_sekinger]

Small interior stuff.   Panel for the gear position indicator, which will also house the 52mm oil pressure guage.  The rest of the engine info is already configured on the Motec ADL.

Mike, I was wondering what type of clutch slave cylinder that was so after a bit of searching it's a Concentric Slave Cylinder, yes?

I always thought the existing method of the Esprit's clutch fork to be a bit janky. Apart from weight saving are there any other benefits such as better feel, speed etc? Probably a bit of an overkill mod to a 'normal' Esprit though.

 

[mike_sekinger]

Yes. It`s the most direct way of acting on a push type clutch.  Engagement is a smooth as it can.

I would not recommend with kind of thing on a regular Esprit.  They are not particularly cheap and there would be a fair amount of bespoke work to get it installed and working correctly.

[mike_sekinger]

More interior preparation.   The new gearshift is off-centre and closer to the steering wheel.

The space on the panel may be used to mount the EWP150 fan controller or some other switchgear.

 

[mike_sekinger]

More small stuff finished off.  Clutch inspection cover and slave bleed nippled secured.

Great work and I really appreciate you taking all the great photos and sharing!  do you use diamond tooling to machine the carbon composite so cleanly?

Thanks, Dave

[mike_sekinger]

Hi Dave,

I use a Dremel high speed cutting disc for the carbon sheet.

Cheers,

Mike S

[djgaloot]

Thanks! how about curves and holes?

 

[mike_sekinger]

Dremel grinding tools for any profiling and good quality drills for the holes.  You just need to drill slowly/steadily.

[mike_sekinger]

Electronics and cable routing. The engine and gearbox ECUs are moving into the cabin away from the heat.

 

There will be a super lightweight carpet, but that won`t be fitted until the body is back on the chassis.

 

 

[mike_sekinger]

550cc/min primaries and adapted fuel rails with -6AN ready for link pipe and removal of secondary injectors.

[mike_sekinger]

Finally together with the gauge

[Modelfabio557]

Glad that we have experts like you to help with our cars!! Thank you for red race ECU I bought from you couple years back 😁

[mike_sekinger]

Painting hand layed lower body section and fitting of the EWP150/fan controller.

Once the painting of the cabin is finished, I will lay the wiring and get ready for the body drop.

[RobinB5]

What colour carpets are you going for Mike?
