Looking good John. Did you see in the Rotrex instructions it says about mounting the reservoir lower than the charger? Mine is still mounted up top but I did wonder about changing it to be a bit lower. I'm not sure what the reasoning is for their recommendation though.

Looks good, it does block off quite a large portion of the radiator though.

As does the turbo intercooler too, yet the car runs at normal temperatures on the road.

Yes we had ours moved by Dom after I spotted something on the Rotrex website technical pages about invalidating the warranty. It's something to do with oil running down to the blower under gravity when the engine is off and potentially passing the seals but beyond that I've no idea. You'd think they must have had some failures because it was an ammendment to the original fitting instructions.

Every time I read John's posts it fondly reminds me of a girlfriend I knew in college. A lovely, shy, catholic girl from Cullercoates, who loved poetry and was studying Mediaeval Languages.

She introduced me to Archibald and Mehitabel, a delightful book of the musings of Archibald, who I think was a cockroach, about his unrequited love for the aloof Mehitabel, who I remember as being a Siamese cat.
Archibald had a typewriter, but being a cockroach, couldn't reach the shift key and any other key at the same time, and also hadn't discovered the joys of punctuation. So he just bashed away lower case without a care in the world.......

Not that John's a cockroach, but the results are strikingly similar

Keep bashing on, John, we love your work and your company.

As above, just a little thread on fitting the SC Power Rotrex blower to a 4,0 ltr Chimaera.

First jobs are to remove the cooling fluid then the rad, and main hoses. This makes fitting the hardware easier. Then remove the power steering pump and the original flow and return hoses as a new pressure hose is supplied in the kit. This comes complete with a new bracket to mount the reservoir either on the o/s inner wing or the front cross member.
Next the plenum chamber has to come off as it goes back on the reverse way. The coil and ignition module come off at the same time. I will shorten the wiring when the coil is re-sited to the other side of the plenum once that's fitted back on.
The main bracket for the blower is in two halves. First piece attaches to the n/s head with the supplied cap head bolts. I tap out the threads just to make sure they screw in nicely; first go with a little copperslip. Following the comprehensive instructions, the power steering pump is fitted to the second half of the bracket before that. Then the polished bracket for the Rotrex is fitted with cap-head bolts and the belt idler goes on at this point. Then fit the blower itself which is held in place with 4 countersunk set screws and one bolt on the rear of the compressor section.
A new one way valve goes in the plenum base for the breather from the carbon canister. I cleaned out the plenum and refitted with the inlet facing the o/s, complete with its supplied plugs to the original breather and the distributor vacuum take off.
The wiring will need to be extended for the throttle pot and the stepper motor. I solder all these joints and heat shrink them for good connectivity. I then start on fitting the intercooler and the blower oil cooler with its associated pipework which is about where I am at now.

I have attached a few pics to go with the text. The manifolds and Y piece are out and away being ceramic coated. The swirl pot is also away to SC being modded to fit the conversion.


John

I like your old school style and charm and also really interested in this thread. I'm too old now to be your apprentice but I can be your workshop manual editor?

So, when do I start?

Another awesome thread, well done John, I always enjoy reading about your work.

[mk1fan]

All done before morning tea break too!

[Engineer1949]

gentlemen will try to do better on the punctuation front i just get going then cant bother to go back and punctuate, but thanks for the encouragement more to come next week waiting for the manifolds and y piece then crack the rest out, been roving a 500ft lift rope on our 75 ton gotwald crane in the yard today so a bit of light entertainment.

john

[Belle427]

Id be interested to know what mileage is on the car and what checks were carried out before fitting the kit such as compression tests, original cam etc. Cant wait to see if it runs ok.
Thanks.

You can't just throw in 75 ton cranes and steel ropes without adding pictures, it's just not done.

I notice it's "ton" and not "tonne".
I trust an engineer who thinks imperial.....

o.k guys pics of the crane tomorrow just as an aside it originally had a v6 aircooled deutz built in 1963 so was well past its best so a few years ago i grafted a 6 cyl intercooled cummins 220 in there been running grand since

That's just teasing now

I could do with seeing this 'thing'. Is your address:

by any chance?

Looking good John, nice to see another of your projects on go

[trev4]

I know if you are looking for bang for buck then turbo wins but I was wondering about heat generated in the engine bay, how do the two compare as I'm mindful to think it it would be better to sacrifice a little horsepower for a little less heat or would the two systems create similar temperature's for the same horsepower.

[mk1fan]

A turbo will generate higher under bonnet temps courtesy of the fact it runs of the exhaust gasses. These can be mitigated by using ceramic coatings.

There's something about a supercharger whine though.
