Need help to calculate.

[Tekken]

Hi,my first post here-nice forum.
I have a drag race vw beetle with an aircooled turbo engine.I really need some good help from you guys,to calculate what jet size/sizes to use based on my fuel jet sizes and pressure.I use a 1S system injected before turbo.

-2,5 litre 4 cyl. aircooled engine,approx 500-550hp
-Draw trough turbo setup-non intercooled
-Modified Holley 850 carb,VP racing fuel MS109

On full throttle with 7psi of fuel pressure,active fuel jets are:
two 1,5mm
two 2.4mm
two 3.2 mm

Thank you.

Kind regards.
