Marks RX7 - lets break a rotary.

I’m taking this opportunity to clean up the engine bay following me losing all that coolant a few months back. Also better routing the loom to make it tidier. Photo is a work in progress

It's been a while, I think you should take the engine out, just so you don't forget how to do it

Meth set up version 2 is nearly done. Just need some additional fittings and PTFE line to complete the change up.

 

[Mark Davis]

Finally sorted - 3400cc per min flow.

Nice to actually see the car being used.

I should have come along to that, woke in the morning and decided against it....

They are doing a meet at Badger 5 in a few weeks.

booked on

Finally cracked it

Almost 6 bar pressure and over 3000cc per min flow.

Ready for the dyno.

Question on this, are you using the water injection for cooling or extra fueling? Both? Could bigger/more injectors have covered it? Only asking as you have had a fair chunk of problems getting the system in and working.

 

[Mark Davis]

Both mate. 50/50 mix at the moment but will be mostly meth for 2 bar, 90/10.

The ball ache with this working as it should has been mostly down to dog shit parts of Aquamist. Now I am using the right jets, manifold and pump it’s pretty flawless and has multiple safeties which has always been my main requirement.

What also doesn’t help and soon to be changed is the feed that’s at the bottom of the tank is wildly undersized, that’s caused 90% of the issues and as you can guess that was outsourced to someone else.

 

[Mark Davis]

The other pain in the arse was the standard 2 pin level sensor, absolute shit polarity so moved to a float level sensor which with a bit of modification just fits in the tank.

Works perfectly now too.

 

[Mark Davis]

Haven’t updated for a while.

The FD is currently in the bodyshop getting a few things taking care of before they get worse.

First thing is the windscreen is out as the seal failed and water had gotten in which obviously started to rust.



Water has also been getting in above the headlining.

Old cut out and new piece added in.





Next up before my ownership it seemed the car had water ingress in the back seat causing a mouldy seat and surface rust behind the drivers seat.





This will all be tidied up and treated too before carpet and seats fitted. I’m going to find a set of bins next year if I can.

Next up rust was found behind the rear pass side spat. That’s currently being sorted too.





Once this is all done the new FEED steps can be fitted.

Glad to see your looking after this.

 

[Mark Davis]

Assuming this is yours @Clarkey ?

 

[Mark Davis]

Patch up at thermomet this morning. Great guys.

 

[andybond]

That really is looking good. I should get my exhaust manifold , and exhaust done.

 

[Duncan Grier]

Definitely on my final spec for exhaust, not only looks epic but seems to out perform most other options

 

[Mark Davis]

It’s certainly noticeable in terms of under bonnet temps too. I think it’s a must for a rotary, on occasion I’ve seen over 900c EGTs.

They are going to make me a lower inlet heat shield too if I knock up a mock up out of cardboard.

 

[Clarkey]

Assuming this is yours @Clarkey ?

Yes that’s mine Mark

Looking forward to seeing the difference in our temps all round when all done.

 

[Mark Davis]

Getting closer to having the car back, likely next week

He’s painted all the bits now and is going to give the whole car a mop and polish.
