    Yeah 1/4 times would be a heap better certainly improve the 2.5 second 60 foot times or what ever it was

     

    couldnt even get full throttle till 4th gear last time

     

    so I’m goin to build a new diff, the current 4:11 diff is goin into the Monaro and goin to try maybe 3.7 with a true track and keep the harrop cover in the manta, goim to build this diff my self as well

     

    if I like it will keep it if not will just get 4:11 gears and swap it over to that

    So got back into it this afternoon

     

    have now fitted a new m80 diff with 3.7 gears and true trac and fitted my old m80 with 4.11 into my Monaro

     

    Did a run and was 420 rwkw at around 6000rpm and fuel system on the limit

     

    bumped up fuel pressure 5psi and still went around the 420rwkw but was breaking down top end

     

    closed plug gaps from 1mm down to 0.8mm did a run and she instently jumped up to 468rwkw at 6500rpm and again on the limit of Fuel system and did this on 13.5 psi of boost and 16 degrees timing

     

    a gain of 48rwkw simply by closing up the gap

     

    anyway 100% certin I have maxed the injectors now and with power still on a upwards climb and should keep goin to 6800rpm we excepted defeat and am getting some bigger injectors

     

    also fryed up the clutch doin a celebration 2nd gear burnout so up for a new clutch plate as well and will try the ceramic one over the organic as it’s rated to 450rwkw and not 400 like  the organic

    Seriously epic, great stuff, incredible difference by just closing the plug gap, I wonder what the theory is behind that gain??  Nice torque curve and linear power delivery too.  Bummer about the clutch, tbh its one of the reasons I don’t pan on going manual, I don’t hear of too many people holding your sort of power with any clutch that’s actually driveable on the street unless you have legs like Arnie.  So are you planning on taking it back out to the drag, would have to run close to a 9 now wouldn’t it if it hooked up?

    Get a mantic twin plate and never look back. With handle the power easily and they are really nice to drive.

    A good twin plate will happen one day but for now I’m just goin to get a cerametalic plate for my current clutch

     

    only $350-$400 for a plate and is rated to 450rwkw

     

    my current clutch has been great rated at 400rwkw with a organic plate

     

    yes Gary I will be takin it down the strip soon but don’t see my self even getting a 10 second pass in it been manual, if I set it up for strip year 9s fearly easy I wreckin

    The ceramic single will be more harsh then the Mantic Twin.

    I do totally agree but It’s more a cost thing a the moment

     

    it’s coming into perfect driving weather and already up for $1800 for a set of injector dynamic injectors and dont have another $2500 o top of that for the clutch right now, plus the Monaro is getting a cam in a couple weeks as well so funds are getting hammered

     

    so will take the cheaper option that will get me goin through the winter then later on when coin is flowing nicer again will look at options

     

    plus will be doin some drags this winter and I will go all spooky of the line if I spend big dollars on a clutch where the cheaper just replace a clutch plate option I won’t care to much about it

     

    twin plate will happen just not right now

    Yea get that, do whats easiest/cheapest at the moment so you can enjoy it.  Not that difficult for you to swap it out later given everyhting else you have done.  You are starting to get into the territory where putting a stronger clutch may put load further own the drive train, but that’s all part of the deal I guess. But imo, to reliably hold 800hp on a streeter the clutch pedal will be firm and a pita if your stuck in traffic, its just how it is, everything becomes a compromise.  Awesome power though, love to go for squirt in it one day…

    Yeah Gary’s that’s exactly right

     

    turns out it’s been nearly 5 years since I brought the clutch and it’s done around 4000km now

     

    mal is looking for 8 or 10 point cushion button plate I can just throw into it witch will hold even more power then the old plate or I can just buy another organic plate $300 witch is cheap as

     

    to me spending something like $2700+ on twin plate set up just isnt worth it at the moment when I have this solution for now, plus if I was to spend that type of money honestly I would probley look towards a 4l80e instead and sell my 6speed set up and I  just not ready for that yet

     

    the car is halling ass at the moment that’s for sure

     

    anyone got any suggestions on injectors in the 1300cc range and e85 compatible, preferably ev14 but doesn’t really matter, could change the plugs on loom if there Bosch style ?

    Thought you were going with Injector Dynamics injectors?

    >Suss a set of Bosch 1600’s.

    >I can’t justify the price difference between the ID’s and Bosch

    I was goin injector dynamics till I seen 1300-1600 are $2000+

     

    if i I can find someone with a set of the injector dynamics 1050x and flow them to see what they actually flow then I would get them at $1000 or so

     

    I’m just having trust issues after my current 1000cc only flow 780 or so cc at 43.5 psi

     

    if the ID do flow 1065cc at 43.5psi then they would suit me perfictly and I would have no problem paying $1100 or so for them but I’m having trouble believing any injectors advertised flow rate

     

    and I’m a little with cava on can not justify the price difference

    I would expect ID flow rates would be accurate as that is what they are known for.  Best bet would be to contact them and see what they say.

    I would of expected Bosch flow rates to be accurate as well but they are way off, I was extremely supprised at how low they actually flowed and don’t know how they can be advertised as 1000cc when they are not even 80% of that

     

    yeah I will keep searching, Thing is 1300cc  injector dynamics cost more then 2 arms and a leg and I don’t know of any other 1300cc injectors that even exist

     

    and the bosch 1650cc ones are $210 each so $1680 a set of 8 witch is still pretty pricey especially when can get Bosch 2200cc ones for like $60-$80 each but don’t know what they will be like down low

    SADly when you get to that level. It’s just one of those shitty things that has to be done

    I forked out for the ID;s after reading lots of pros and cons.  Fwiw my tuner hadn’t had much experience with them before and was skeptical.  After tuning mine he was impressed with the info/data that comes with them compared to the straight Bosch, he liked them.  I am not up to speed with all the stuff in the ECU but you may be as to what he’s actually talking about.  Imo you get what you pay for, but yes often the best comes at a premium.  Surely a car at this level needs the best (again imo).  Might be best to speak to your tuner on what he thinks?
