I'm having it LARGE for 2010 :)

I've fitted my new spider plate now. And a new Harcourt manifold, and a Weber 600. Absolute shite combo
The weak link being the carb with vac secondaries. This big single plane mani does not develop enough vacuum at instant wot opening.
She rev's like a demon and very fast when I blip the pedal to full opening on the primaries. But if I try a quick opening to full throttle, she bogs flat dead when the secondaries go full open.
I've also done a lot of flow testing, and discovered a problem with my nitrous supply lines. Most of 2009 I thought I had been hitting my regular 10.6 1/4 mile times with a 300 shot of gas. But I have proved that I have only been flowing 240hp of nitrous. So all my dyno info is way off regarding the amount of power I've making for X amount of nitrous.
So!!!
I've got a nice Hoilley 600 double pumper on the way from the good 'ole US of A as I write. And a new set of MT slicks, but this time they are 27.3" diameter as opposed to my 26" diameter that I have been using. These are to go on my new 15" slot mags (for new read, new to me!)
My existing nitrous sytem can now flow a full 300hp of extra gas and petrol. And I've got another spare nitrous kit than can flow an additional 150hp of nitrous and petrol to bolt on if I need it to get me a 9.99 in 2010
I've decided I want to see just how fast she will go on stock heads and a tame cam before I do major engine work.
If all goes well I'll be doing shakedown runs late Jan or early Feb 2010. The reason being is that I want to try for a low 10 with the system as it is. If I can do this I'll leave it as is and be ready to race for the Fast Show.
Once I hit a sub 10.5 second pass. I'm going to stick more gas on to see how much she will take before she breaks.
I've also just bought another full manual auto gearbox with a transbrake kit fitted. That will surely kiss the old rear axle goodbye.
