Clive's 3 Rotor 700BHP Monster Thunder Saloon Project

  Super exciting times! (Not talking about above mentioned Yorkshire backside)

More progress in the huge effort by all to get the car attending Brands next week and getting temperatures under control, because of the physically bigger Cosmo 20B engine that now carries 50% more oil and water than the 13B engine did.

A big  Koyo RX-7 FD Duel pass radiator was ordered on a special next day delivery from California to be here yesterday, but sods law, the first time for years it got trapped in customs but should be here Monday, then modified to fit.

Because a Rotary derives much more of its cooling from oil, than a piston engine, today I fitted two monster 34 row oil coolers in place of the tiny Mazda Coolers.
 
Really pleased that 10 years on, the Racing Beat oil lines that have never ever been a problem, bolted straight onto the new Mocal coolers.

Made more progress today. Fitted the new RX-7 FD Koyo Rad that finally arrived, engine block temperatures have come down from 110 degrees to 86 😁. Cars booked for the Dyno wednesday so fingers crossed it will be OK for a full day test Friday and then if all is well two Race days at the weekend.   Sadly the air horns had to go to make space for the intercooler 🙄

Fingers crossed the dyno session shows some good results and no (more) issues !

Looks positively menacing!

Good day yesterday and we are 99% further forward than just a week ago.

Ran the engine all afternoon on the Dyno with the Cooling under control and yes, we can go racing however with very reduced boost and horsepower, as we found a boost leak that appears to be from the new lower manifold that I will strip off today.

 Should be interesting to drive even in this form as full power comes in at just 4500rpm!!

[MattScott]

Great news that the only issue found is a leaky manifold and loving the turbo peaking through the hood

[Jamie R]

She's ready to go !

Great news

I opened this peaking through my fingers just in case I was again greated by Northern arse but this video is PG
Good to see Christine running again and getting ready for test day.

Pleased to say the 3 Rotor ran faultlessly doing 62 laps in total, running hardly any Turbo boost or revs due to running in, the car got down to a 54.3 on the Brands Hatch Indy circuit, whilst its not very fast for racing over the weekend, it gives me an idea of what's to come.

There's a short Dyno from Wednesday that you have seen above and a couple of shorts of the car going up to Druids on the link below. HUGE thanks goes to Jim, Pip and Steve for making the 3 Rotor Project happen and work.

Great news and progress Clive. Now you can dial her in and get some miles on her so you can turn that boost up!

I've posted some shorts on YouTube.
