Beachcomber's 940 - Supercharged

ooops - sorry folks, just realised I've been posting in the wrong place !

1991 940 2ltr / auto wagon getting the treatment [ mild ].

The car was well looked after [ pampered ] by the PO, who spent obscene amounts of money !

No rust or even corrosion, even my MOT man commented on the condition - flew through it's annual test - nothing required and no advisories. Tail pipe was iffy, so I replaced it anyway.

Started out as a mild cosmetic makeover, then the erratic starting / lambda light flashing syndrome started. To clarify - I am NOT of the modern era, far more at home with carbs, dizzies, and strictly NO electickery for me. So I took the decision to go back to my roots - Mechanical Blower [ Eaton M62 ], draw through with 2"SU carb, retro fit dizzie, etc.,etc - and ditch all the electronicky bits. That, I can understand, tune, fix without resort to getting other peeps to sort out.

Started off by lowering 40mm all round + Bilsteins. Fitted tow bar and bought OEM roof rails - the car will be my only daily driver when complete and must be reliable and practical.

The bodywork is superb, and apart from one very minor scratch on the o/s rear and a minute ding on the n/s front wheel arch - the paint is also spot on. Just a pity it's Silver .... too many silver cars in this world!

I'm going with Jag 16" alloys - just to be different ! Had a trial run today. Fronts OK with 40mm spacers, maybe 20mm on the rear so I can get some wider rubber on.

One week after as bought -40mm springs and Bilsteins all round









First thoughts on blower location. no go. Blower now sitting on it's "back" under a new K inj. log type manifold. Carb will sit at rear, via a 90 degree swan neck intake.

Packaging looks OK, and I have a spare 2.3 Turbo engine to mock everything up on. That'll be on the engine stand in next week or two.

draw through i like!

That's me - REAL old school l

My early playthings mostly had mech blowers - all with draw through. Even our Chevy powered altered ran injection through the blower ! Albeit using Methanol.

Most peeps are saying - just fit larger turbo. But power is not my goal here, just practicality and my ability to fix problems myself.

And, after a working life (40 years ) designing and manufacturing replica and speciality sports cars - I do like to look into the "whatifs" in life.

Remarkably, the actual packaging looks very straightforward.

Thanx for your interest.

i wanne do something similar in the future, but for fueling i definitly go for propane (lpg) straight propane is very easy with turbo. (and its cheap) so milage is no issue.

SU carbs can do the job also ofcourse.

I'm speaking with "Classic Swede" of this parish. He's an LPG guru here in the Uk, and of course specialises in Volvos l

He's already suggested a system that will suit my planned SU system.

Like I said, this will become my sole daily driver for the foreseeable.

I was trying to find someone to machine an adaptor for me - SU carb intake manifold to Eaton blower. No takers so far.

Then I tripped over a billet alloy propshaft spacer for a Land Rover - EXACTLY the size I need !!

Just need to drill / tap the relevant fixing holes.

So, quotes in for the various bits of fab / welding etc. [ NOT including the SU manifold ] came in ?175 !!!!!!!!!!!!!#

Then this little gem came up. Obviously set up for FI, but all nicely laid out for my application !

Feed is pretty well under the K inj log manifold to connect to the OEM throttle body [ less throttle of course ! ] and the injector body inlet can easily be adapted for my SU plans. That means a simple 1/2" block with relevant mounting holes to mate with the blower adaptor inlet and the job's a good 'un.

I can even use the bye-pass if needed. This unit produced 10psi on a 1.6 Ford Zetec [ whatever that is ] and 160bhp at the rear wheels. The designer / fabricator was quite happy that the blower would safely take another 20% overdrive. That leaves my M62 to sell to reimburse most of the cost. Win -win.

The silly / hooligan part of my brain is saying ............ + NOS:thumbs ??_up:

Price ?200 ..... no brainer, that included the M45 Eaton BTW !

Looks like I resolved the front spacer probs as well ! To clear the hubcentric boss I needed to remove 10mm - or conversely, add a 10mm spacer ! That also resolves the problem of the wheel studs being 7mm too long [ 2 birds with one spacer]. Then bolt the aftermarket 20mm spacer kit I already have with yet another 10mm spacer to clear stud protrusion etc. Simples - and cheap. I also have a selection of 5mm shim spacers, so I can play around and get the wheel position where I want it. Looks like a 20mm + 10mm shim spacer on the back will give me clearance for a 245 section tyre - maybe even a 265.

Still need an olde Worlde Dizzie and auxiliary drive shaft.

Decided to treat the old gal to some grooved front discs - ?28 delivered !! What would we do without EBay ?

Pix later - not loading at the moment.

And here's the unit - modified M45

This is going to be good.

Thanx for your encouragement. I'm actually excited at the thought of attempting something a little different. Back to my roots !!!

Looks like it's going to be a lot of fun!

(And if you ever decided you don't want headlight wipers let me know, keep trying to track down a set )

After almost a year of inconsistent starting / running issues- the car has now been starting FIRST TIME,every time for 6 weeks. !!

Time to put it back on the road and temporarily retire my V70. Hope I don't regret it.

That will give me a bit more incentive to get it finished, although the engine swap ( Eaton supercharged ) won't happen a while yet due to funding issues.

Wait, you are using a supercharger that made 10psi on a 1.6 and 160hp? Instead of the bigger supercharger? That seems really backwards, not just from a install pov, but from power given an engine that's roughly 30% bigger is going to Max it out at a lot lower revs... .
Especially if you go to a 2.3.

Sorry duplicated

Correct - the PO was running the blower 20% under .........the Eaton can safely be overdriven 20% - ie 40% more than the previous installation.

My goal here is not speed / power ( I have a Hayabusa for that ) but simplicity and the ability to fix problems myself.

Oh ........ I do have a 150- bhp NOS kit sitting around, just in case. ................

Thanx for your interest.

BTW - here some of my previous projects and playthings

502ci Ford 3 stage NOS / Powerglide Comp Altered





A couple of of the replicas I manufactured







And two wheels



And when only a supercharger was the fun way to go.

Love this, all thumbs up for the blower!
Altered's and Porsche kits? do tell.

CH - thanx for your interest and support .........it WILL happen.

Very long story ......................... VERY short.

Been involved all my life in speciality cars, circuit and Drag Racing - building V8 engines [ oh yes and superchargers ] and generally going fast ! The altered shown is the ex. Lawce Bros & Gunn Altered [ 6.9 185 mph in 1972 ] which we imported and ran for 2 seasons before selling it on to the Swedes. The 27T Roadster is "Mr.Shifter" - as you can see, I was heavily influenced by one Eddie Sigmund ! Later I re-named it "Shiftin' Sands" ]

Early days [ 70's ] ran a company called "Americar", specialising in American speed equipment, car import etc. with my good pal Keith Harvie. He went on to found PAW [ Performance Automotive Wholesale ] in California. I stayed in the UK and opened my own speed shops - "Muscle City" being the most well known in the UK, and in the early 1980s followed my other passion - replica sports cars.

Then followed 25 years of design, manufacturing and sales of Porsche [ 356, 550 Spyder ], Jaguar XK120, and of course Cobra! Nearly forgot - also a 27 Track T - the "Mongoose"

I also did consultancy work for RAM Automotive with their Cobra and D Type Jags securing a deal with Carroll Shelby along the way as the "only replica endorsed by Carroll Shelby".

I worked directly with Carroll to represent his Organ Transplant Trust in Europe - becoming the European Liaison Manager.

When I retired [ ha, bloody ha ] in 2000 - I continued to carry out engineering design consultancy work for my main German agent [ Mohrspeed ] and with my pal at RAM - which I still do. My last commission was to slot a blown V8 Jag into the C Type rep. Four sold to date - and BLOODY QUICK. I also carried out work with my German pal who now owns the rights to the name "AC Cobra".

This also involved - the various Cobra variants [ race and road ] for RAM, and Gullwing Merc, Porsche T6 roadster and Cobra projects for my pal at Mohrspeed.

Bet you wish you'd never asked now !

RAM www.realmengineering.com. an old website, but will give you a flavour.

Potted pictorial history [ very short ! ]


two of our reps on display at the Goodwood Revival - most folks thought they were the real deal !



Another 502ci Ford lump - this time in a Reliant Scimitar bodied Modified.

Our Altered on the front cover of the leading UK mag. at the time.



And last but not least [ over 150 kits sold ] my Mongoose Track T.

Very nice. Which confuses me as to why using efi and the bigger supercharger with an adapter made by one of your friends for a few hundred pounds seems like it's not worth it?

A kjet manifold may suit your build better Though.
