Malone's 1.6/1.9 Frankenmotor

[935racer]

Balancing has nothing to do with the vibration froma  knife edged crank, well unless you idea of knife edging is going at it with a angle grinder  The more weight you take of the counter weights the more the enginne vibrates, theres a reason why diesels have big heavy crank counter weights.
Mark theres a good chance most people will never ride in a car with a knife edged crank, its a really high performance thing, for really high revving gas engines, and I'm not talking about 7k more like 9plus.

Jake thanks for the link!

I thought I'd start a new thread to collate the known info about the frankenmotor in Malone's car, as this sounds like a combo I could get interested in building. Hope you and Dave don't mind!  

1.6 hydraulic block(? - are there different blocks?)
1.9 hydraulic head, ported and polished with the 'head mod' (any pics?)
1.9 hydraulic cam (Stage ?)
GT20 turbo (how does this differ to a KK24?)
Big downpipe and open exhaust

Pros - 143 hp and 165 ft-lbs of torque

Cons - misses and smokes off idle in present state of tune
        - 5250 RPM appears to be effective limit with 1.6 IP

Any gotchas to building this or important factors I've missed?  

One last (initial) question...why build it as a 1.6 instead of simply hopping up a 1.9?

TIA!

Since no one really answerd the questions directly yet.

1. Yes it is a hyd block, yes there are both hyd and solid liftre blocks
2. Yes, none yet, mabey this weekend if they feel like pulling the head agian  :roll:
3. 1.6 hyd cam, as I belive the 1.9 cam we recived was damaged.
4. It spools faster and has a bigger PR and flow map.

Audi80 from Finland, can you please enlighten us on the 254whp and ~360wtq 1.6TD you claimed in another forum? Since the owner of that TD also owns a dyno, can you ask him for a copy of his dyno charts?

Cheers,
Mark

I donīt know him personally, I have visited his dyno few times. So I donīt know the details of his Caddy. I think it has ported 1.6 solid head with bigger valves, stock pistons, Pauter H-profile rods, custom headers, custom intake made of Volvo intake, custom 12mm pump. Iīm not sure of turbo, probably T3/T4 Hybrid.
I can ask dyno chart, I have seen it.

BTW Caddy looks like this  :lol:  
And smokes a little, me with Sport Satellite on the other track.

Brett's correct, I'm currently running the 1.6 hydro cam in my 1.9 head as the 1.9 cam I received was damaged. The stock 1.6 cam's pretty lame.. can't wait to try the performance cam!

I can ask dyno chart, I have seen it.

That'll be great!! I'm very curious as to know what the torque curve vs. RPM looks like. That Caddy is quite the sleeper

BTW how many seconds does your Plymouth trap on the track? 1/4 mile (402m) or 1/8 mile (201m)? Any times from the Caddy?

[Audi80]

My best time is 15.1, 318 4bbl with headers, 2.76 gears, no suregrip and with 205/75/14 tires. Caddy flew past me before 1/4. I think his best times are around mid to high 14s without any traction if I remember right. Itīs not built to quarter mile with those little 185/14 tires :roll:
Yeah, itīs quite a sleeper. He likes to fool around with big Mercedes and BMWs at the highway. You would never guess how fast can old and ugly diesel Caddy be  :lol:

I wonder if it's possible to de-stroke a 1.9 block. To what extent? Any good crank options? I suppose that longer custom rods could be used with a smaller crank to retain sufficient piston protrusion (TDC) without needing to deck the blocK.

You could use an AAZ block with AAZ rods and pistons only replace the crank with a 1.6 one,It will fit and rod journals are the same,You'd only have to take 5mm off the deck to get the piston where you need it,IMO the aaz block looks like it could take the cut.The cylinder head bolt holes are about 3mm deeper on the 1.9 block when compared to the 1.6 and coolant passenges are parallel for around 5mm too :twisted:

[935racer]

Good idea except taking 5mm off the deck of the block is gonna screw your timing, Custom rods would be the ticket :twisted:

[andy2]

5mm was an educated guess,If someone were to put a 1.6 crank in the  1.9 all you would need to do is put the piston is at TDC then measure how much material there would be to remove from the deck.I may find some time myself to measure this setup and see if it would work :wink:

[Fionn]

Sorry to bring up such an old thread.
Just wondering if the cons for this setup were ever eliminated?
I'm doing a rebuild at the moment and found out today I'll need a new cylinder head so I'm considering a 1.9 head.

[jtanguay]

i still want to see the dyno of that caddy...  :twisted:

[subsonic]

I am in the process of building one, and Dave just build one for Brett.  We have a group buy going on new 1.9AAZ heads in the for sale section.

[Fionn]

Hi, Yep I saw that (the group buy) which made me think it must be a viable option.
Is it now a mature setup that can be easily set up to run reliably?
IE If if buy a new AAZ head and bolt it onto my rebored block with a 1.6TD pump and 1.9 head gasket will there be any major steps to get it going well?

I'm getting the block skimmed and the pistons done to match also, so I assume that I should run with the thinnest possible head gasket in order to increase the compression and reduce the smoking startup problems?
Will a thin HG be better or worse in terms of supporting high boost?

Finally has anyone tried getting the piston faces machined to better match the prechamber ports on the 1.9 head? I might try this while I have the pistons out.
