what vintage is your engine Don


my point being................ single layered plate will add some strength, but very little to area's that require attention "3sgte"

Elise engine...... its clearly visible that the combined layers making up the bottom end section have greater depth than a piece of 10mm/12mm plate,

elise engine was it not made out of very poor quality metal and the block suffered from enormous distortion............+ its not big power either...

Nice girdle..

How much machining/milling it requires to become compatible with rev3 3S-GTE?

Who knows?

DJ, my supercharged K series engine was built in 2001.

You are right about the engines being of variable quality. Some blocks were badly cast and/or out of alignment indicating that quality control was poor to non-existent. The K series is more like a motorbike engine and runs very little coolant. The only way to get it to survive double its design output was to construct the lower girdle and use the through-bolts to clamp the whole head/liner/main bearing assembly. The aim being to limit the stresses that whould have to be endured under forced induction.

The supercharged 1.8 litre Type R Honda's fitted in the Elise's which run in the Elise Trophy series are allegedly putting out around 320bhp but even they have reliability issues. Steve Guglielmi's Audi 1.8 turbo engined Elise is around 350bhp I believe.

All of which says to me that a 500bhp 2 litre 3S-GTE isn't too shabby compared to these young upstarts especially considering the engine design is over 20 years old Same could be said of the Cossie YB.

The ultimate production unlinered iron block must be the 1959 vintage BMW which was used in the 3 series road going saloons....end eventually ended up in the back of Nelson Piquets Formula 1 Brabham BMW chucking out 1,500bhp in qualifying trim

supercharged Don, sweet i forgot.



probably easier getting them roughed out using water jet, then finish using mill, but dependable on design.

variation of model type 185 or 205 will require different setup, or update 185 oil pump & sump to conform preferred option.

would of thought after market / custom sump would be high on list, consider ultralizing construction " heavy duty webbing" making sump design similar to the Elise configuration, sump construction can indeed add close strength into engine block this is an area that should be developed, its used elsewhere on 4 potters with good results, its not just about engine loads from the inside, but external loads.

take for example todays touring car, engines are light, offering a little under 300 bhp NA, okay not massive power, but constructed from minimal material throughout, as such have support cradle, sharing loads from engine, transmission, chassis etc..

strapping of the bearing tieing in to angles a must, external gantry would offer further gains sharing engine mount loads, especially cam wheel side, that whole mount is fixed in one little area, other similar vehicles have rigged mount to contact 2 sides apposed to just one flank.

Quick question...
Is it worth going for the American fabricated girdle?

Based on the fact that the dutch girdle is not available and the american one is, plus, surely any girdle is going to be better than none.

Any thoughts?

I'm trying to get more info on the Dutch girdle. Arnout told me it he'll only sell them if there's a minimum of 10 people buying it, the price would be roughly 200 euro/ea without the ARP bolts used. Thickness is 2x8 mm. He chose this design because it still allows the gen3 oilpump and pan to be used without problems. The engine it's in is quite interesting too, it now has an Eaton M64 supercharger for the lower revs and a Garrett GT40 for the higher revs;







^ Yes, the bonnet still closes. Only just

Any other things you want to know? Let me know so I can ask them

Um, Everything please René

Layout - does the turbo feed the supercharger, or the supercharger feed the turbo or they are both in parallel etc etc etc etc

just love seeing engines with oil ways left open, hopefully its a mockup engine.

supercharge is the way forwards, just don't see the room , how's he mounted it, its all very limited.

the engine on the faffs must be further back when compared to the 185.

project six million dollar 185, faster, stronger, lighter than before.

talking of cylinder wall thickness, NOW can provide full 3D cylinder bore thickness from inside solid works via rs232 from the thickness gauge..

each cylinder modeled from 120 to 240 data points..

I thought I'd keep you guys updated on that twin charged 3S-GTE setup Arnout is building including a new version of his girdle;

The plan is to run 2 bar of boost, so they've enlarged the piston ring gap with 0.05 mm.



Thickness difference;







Space needed for the supercharger pulley;

their goes the inner rail making room for mr supercharger nice, just space frame it.

the griddle designed used on 800 hp yb build was about an inch thick set into the cast alloy dry sump which was another inch, massive webs across corners allowing getrag to hook up on 8 points not 4 same setup has been used on the 1080 hp yb and 1200 hp evo.. all big fat construction..

Rene,

Is it possible, if you'll take the layouts of this girdle from authors? With further input or resend...

Please...
