Hi
Started this thread ln the old forum
all gone didn't save it.
The idea was/is Subaru 5 speed trans (done and stored and recorded in the old thread) behind an engine with more torque than the engine I have now (which hass more torque than a sandard 2ltr)
The design is the result caused by motor way driving (which we have to do North or south from the central coast)
While my current 2ltr can sit well over motor way speeds (and does) it shows its' short coming's up long inclines, some up the southern tablelands some north of Bulahdelah also mount Ousley, Kings highway blah blah. While we can keep up a reasonable speed in these areas it is slower than modern traffic. The problem with this on motorways are heavy transport.
Picture this.
Driving along at 115kmh (lets face it that's what everyone does). Second Hill out of Bulahdelah (kilometres long) kombi speed drops to 100kmh so left lane to let the tradies past. Truck up ahead going 30kmh (some less), we're fucked, down to 3rd and 2nd while more traffic passes and we have difficulty regaining speed speed fast enough to enter the right lane.
Answer.
Have enough torque to maintain motorway speeds up inclines in the first place.
I researched the idea of a torque monster.
Everything I looked at was about horse power which is a calculation of torque and rpm. If you want to be a part of what some idiots are proposing with 200hp+ then you'll be spinning your engine over at 7000rpm + good luck with driverbility because you'll have nothing around 2800 to 3500rpm where driving takes place in a kombi.
I had a conversation with Wayne Penrose (I've done a few steering boxes for him) who mentioned a 2.7ltr with a torque cam (definitely a torque monster) and was thinking of going that way.
Along came Ian (Ian&shelly not sure if he moved over to this forum) who asked me to help him with a 2.3ltr kit he purchased from AA performance which I agread because I was interested in the potential gains in torque.
Long story short we sorted his engine and with a set of 40mm idfs (Italians) we tested its torque up an incline out of Ourimbah to Peats Ridge (reasonably steep Run) after sorting the carbies out.
My kamper fully loaded just holds 100kmh up that stretch. We sailed up there effortlessly in his and I had to back off after we reached 130kmh half way up.
I was convinced this was a better way to go and after discussing with Wayne penrose (who mentioned I would need to upgrade the cooling system to DTM or Porsche to go 2.7ltr) I made the decision to get the high end parts for a 2.3ltr from him.
So I now have what I need (It's only taken 12 months, maybe a bit more) and 3 sets of cases I've had machined
The CV case is what I'm building for Blitz
A "C" case (this is a low mileage replacement case) that will be a 2ltr turn key engine (complete) with new parts that I have for sale
A CV case which will have a reground crank, new bearings,Engle torque cam and bearings and Shadick oil pump (so bottom end) for sale.
I'll have pics of the bits soon as the with Pryce engine being balanced atm (they have a really nice Sunnon balancer) so until I get the stuff back I've modified the oil pickup on the CV case to overcome the type4 syndrome ( See pics)
I plan to do this on all the cases.
