    Default 4AGE Team Toyota Australia dyno runs

    As many of your are aware, at work we have a rather tasty Mainline chasis dyno with lots of data aquasition, we also have an SF-600 Flow bench AND an SF-901 engine dyno.

    Well I have been getting the engine dyno up and running and while looking through lots of old paper work came across a number of dyno runs perfomed on the engine dyno back in the mid 80's!!! These runs were 4AGE Team Toyota Australia's engines. so I'll put up the figures/specs of engines etc, there is pages of info and data, but i'll just post up specs, power and torque.

    I will type exactly what is on the print out sheet.

    Final rally spec

    8000 125.8 191.6
    8500 127.6 206.5

    What I find interesting is this, what were these engines capable of?! If you have a look at the last few engines, they still have torque/or the torque is just SLOWLY starting to drop away, so if these engines were revved through to 9000rpm or 9500rpm, I wonder what they would of put out.

    Anyway I think it's interesting info.

    That's actually very interesting, cheers dude

    And all are just running chipped std ecu's? And the bottom one has an additional timing thing controller?

    What does MOP Mean? fuel octane?

    With 320 degree cams, why didnt they rev them out to beyond 9500 like you said!

    Would have expected 320's to make around 220hp at 9000+ yeah?

    Interesting stuff, nice find.

    in the group A days you had to run the std plenum and std butterfly but could port head and clean up the runners in the plenum and also had to run std exhaust manifold as well
    comp and cams were free and i think when the ae86 1st started std rods ,were to be used as well

    MOP will be cam centre line.
    so 320 deg inlet cam at 100MOP would give inlet valve opening 60deg BTDC and closing 80deg ABDC. So changing the MOP from run to run will change overlap, where valves open and close.

    I can't elaborate anymore on what I have there are no pics or anything, there is more data on printouts but I guess this is all we need.

    Many years ago I got the chance to have a good talk with Bob Holden, who raced 86's and 92's in Group A.

    He saw my AE86 and we got into a bit of a discussion about them. Even though it was years after he had run his 86, he still knew every little detail, cam timing etc, it was an interesting talk.

    Anyway he was saying in the early days of racing the 86, they were using standard rods, and if they revved them, they threw rods, also the inlet manifold was a restriction at high rpm. Anyway the factory cars could rev higher, eventually someone put a protest in or something like that and they got to see inside the factory engines.

    Lo and behold, Carillo rods, Bob said "you can't do that, they aren't homologated", they said "yes they are, Formula Atlantic", they were using a loop hole to use them, so Bob started using steel rods, but not carillo's as he couldn't afford them.

    Also Homologation for 86's for group A racing was actually done in the UK believe it or not. Anyway Bob was in Japan picking up some TRD parts from TRD, they said come down and look at what we're sending down under to race.

    Anyway they showed Bob what was very close to a sports sedan, Bob says this to them, they get upset and tell him to leave.

    Anyway over night he gets a phone call from a good mate of his from the UK, this guy was actually involved with the homologation of the 86's. This guys says to Bob "expect a call from TRD, I told them if anyone knows Aussie car racing it's you"

    Anyway the next day they come and get him, and ask where their car has to be changed to fit in with the rules. He said they had cut all the inside panels out of the doors etc etc.

    We had a discussion about the spec of my car, now back about 12 years ago, TRD blues etc were very expensive, he commented on how I could afford TRD shocks as when he was getting them back when he was racing the 86 they were VERY expensive. He ran the same shocks as what I had in the car.

    and believe it or not he actually preferred the AE92 to race than the AE86, when asked why, he said he could race a FWD faster than a RWD. The guy can obviously drive as he has won Bathurst.

    At first duration was free and lift was as per standard cams, then later on(not sure when) it was a free for all.
