ahh i may well have miss read it.

would the nitro have the same cooling effects as water when injected into the air stream?

Thanks for that. :wink:

Think i'll be leaving well alone for now until i make my first million!!

Bigger IC and Nitrous looks like the best option.

any problems with nitro running through a 0.3 jet?
considering using direct port on the nitro.

well i just bought a 2nd hand aquamist with dds2.
can one pump handle 4 x0.3 jets and can i run that from 1 hsv?

will i need to replace the seals in the pump?

Yes, each 0.3mm jet flow 75cc/min. On HSV and one pump is perfect.

You must also order a 30um inline filter and used as a secondary filter after the main 100um filter. This is because the 0.3mm jet has a 25um filter inbuilt and will clog up quickly if you don't have the pre-filter.

will nitromethane attack aluminium?

I will drop a piece of ali into the nitro for you and tellyou the result in a few days.

cool, i have a spare alu tank that i dont want to use for the water/methanol mix, just wondering if i can use it for the nitromethane instead.

Hmmm...

Why compromise, inject 100% nitro!!!

I don;t think you need water in the mix. Get a separate system purely for nitro and leave the WI alone. It might be useful to suppress detonation if nitro induces it.

I think you can get a low cost water injection for that purpose. Hotrod and I both agreeed that you will get about 3-4 hp/100cc/minute. if you are aiming for 30-40 HP, go for injection rate of 1000cc/min. In drag racing terms, a 10-second pass will only use up 180cc of nitro - pretty cheap fun - cheaper if you only inject after 1/8th mile.
