Drake engine pictures,

i started this discussion with my engine builder back in 2008, he has a steel crank 'on the shelf' and i have given him the correct block and head castings. Its all very doable, but we would do it differently to the way keith has done his. Bill has some good ideas around traction-limited boost control which may allow it to work, but its one hell of a shot in the dark. Not had the bottle to properly press the go button yet. But the potential is massive with ever evolving turbos and control sytems.

Now the other interesting possibility would be to use a 1900 4 pot turbo, and miss one power stroke per cylinder per cycle, alternating between cylinders. So effectively it would be a 3 cylinder engine, 1400 turbo. It might also shake itself to bits. And the MSA might not believe you it was only firing 3 cylinders in any one cycle.

Other option is to run either an empty or a dummy cylinder, and build a proper 3 cylinder engine inside a 4 cylinder block. Again 1400 turbo. Plenty of 3 cylinder engines around so obviously doable, yamaha going to 3 cyl for latest R1 and R6 bike engines.

Its all possible.

 

An interesting idea(s).

You'll never get the MSA (or anyone else to buy in to the missing firing stroke. Some clever electrics etc and you could 'cheat' in all sorts of ways - not that I'm implying you would of course.

The three cylinder idea is interesting. You could get a bespoke 3 pin crank with a blank end made to get the balance right and possibly that could work but it would sound s**t, you know I'm right! The only decent sounding 3 cylinder engines are two stroke, now they sound the dogs bits! If the three cylinder turbo and the FSi head engine were out together and the three cylinder one won you know which one everyone would be talking about

The electronics for the 1.4 turbo would certainly be interesting and it's all out there and the costs and availability are so much better.

I'm still sold on the N/A option though.

 

On a different note, just missed out an alloy block this morning for 30euro

Interesting seat thread that, I think your mans price for a custom crank is a bit high no? I priced 3 customs off an american company and they all came in at about 1300dollars - me doing all design. Thats not including the vodka and tonic when it lands at door but still 'affordable' ....

As with Tony, Im sold on n/a, theres a few things I dont like about turbos, the turbo being the first!

Brian,

 

Beg to differ - 3 cyl Ford Ecoboost - Chris Harris seems to like it!

Thats my feeling over the missing firing stroke also, it would never be allowed - no different to 'std road cars' being chipped to death these days though..... But a pukka 3 cyl, that could be very interesting, especially in 'big bang' format to tame the turbo torque in FWD application.

 

Rob, 3 cylinders make the engine gods cry lol

Actually, did any of you see the 'new' inline 6 bike engine? 1.6l and very small, Im sold on it. They are dear yet though.

One in a mk1 golf would do me fine please and thank you.

Engine tips scales at about 100kg with 160hp and 175Nm, the average stock 16v Abf with 100k miles has around 125Hp and 160Nm and is about 170kg.

Not a fan of bikes really, and defiantly not bike engined cars but MY GOD listen to that bike go.

Anyways back on topic!

Brian,

 

@ Rob, how could you forget the charade lol

Brian,

That is a signature statement lol

 

Sorry Rob, listened to them all, doesn't do it for me - with the exception of the MV but that was on triple open megaphones!

That said anything on open Megaphones tends to sound good!! I don't mind the turbo whine though.

I've a bit of time for KMS and have some plans for their product. That vid Brian put up proved the theory but don't know that the 20v is the best way forward.

Some of the American piston companies do 20v conversion pistons for the older blocks so others see a reason for offering the option for the conversion to an older block - which is a positive I guess.

Now six cylinders, I believe that is the best sounding engine you can get. Shame the VW offerings are so flawed - but that's another story :-). Unfortunately of no use to us in this thread :-(
