Plate...
Got this cheap- nice & thin and is a NOS item, but is it fixed in how much power it delivers or do you put jets in the ends within the fittings or something? Aiming for about 75bhp...
you put jet in the ends, there are 2 different sought of jets, flanged or funnel type, yours looks like it could be flanged type like mine, rich

have you got the solenoids, mine have metal tubing from them to the plate, ive only got braided tubing from the nos bottle to the nos solenoid, the jets will depend on what fixings you have from the solenoid as to flanged or funnel type, someone on here will give all the in and outs of what you need, i cant remember the jet sizes for a 75 shot ,real steel do them about £3.50 a jet and they do the braided hose aswell, rich

That looks like a slightly chopped 75hp plate.
You need to show us a pic of the connections so we can tell if you need flare or funnel jets.

The info you will get from Real Steel re jet sizes will be.
36 nos + 42 fuel = 50hp
42 nos + 47 fuel = 75hp
47 nos + 53 fuel = 100hp
55 nos + 61 fuel = 125hp
63 nos + 71 fuel = 135hp
73 nos + 82 fuel = 150hp
Now!!
Bearing in mind that the "actual" power delivery depends on nitrous pressure and fuel pressure. Try to get Real Steel to tell you what pressures the jet sizes are based on?
In fact, email Holley and ask them the same question.
I tried for ages to get Holley to respond. Which is why I pulled the whole system off and went over to the Wizards of Nos system.
I now know that at 800-900 psi bottle pressure and 5psi fuel pressure my 80hp shot of Wizards gas makes my car a lot quicker than it used to run on the 150 shot Holley setup. And it uses less gas

Due to better atomisation? Thanks for your help guys, I will email real steel, would I be better to use a couple of foggers or something instead of the plate?
Also I dont know if this should be in the forced induction section but can someone tell me: Will I get a better cooling effect from nitrous if I inject it in before the blower (i.e. plate system) or under the blower where the air/fuel is already compressed (by means of say 4 injectors in the side or the manifold- which will also be a bugger to fit!)

You would be better off buying a 4 nozzle plate from the wizards like I have.
Same shape but a bit thicker. It has 4 crossfire atomisers mounted so they fire down just under each barrel of the carb.
For the max perfomance you could buy a Spider plate from them. This unit gives the option to fire the mix into the individual runners. And you can jet each cylinder individually if you want to. I'm saving for my Spider plate now.

I'll be keeping the plate for a while yet as I've been credit crunched
Instead I'm going to fit a home brew add on to my present system to make it two stage again. 1st stage progressive and 2nd stage fixed hit. Its a bit of a lash up but it will give me the option to run up a 225 shot on each stage. Not that I'll ever take it that high. I'm only looking for another 0.7 of a second in 2009

I forgot to mention. There will be a slight cooling effect on the charge if you spray close to the inlet runners in the manifold. The further away that you spray the gas from the inlet runners the better the cooling effect. But that will reduce the effectiveness of the nitrous somewhat.
Ideally you want to be spraying liquid as close to the inlet valve as possible for max benefit. I'm sure it wont be long before someone comes up with a fuel injector system that will spray straight into the cylinder.
If you think about it. A system like that could possibly run an engine on a sprint without even needing to have the carb butterflies open??
So you have have a lean burning economical engine for road use, and then a monster when you activate the "in cylinder" injection.
Food for thought eh?
