NITROUS OXIDE ( nos / n2o ) advice forum

got bottle in fixed bracket on old center stand mounts and one on top of swing arm . had to move air tank and catch can so need find place for them . fitted Venom's just got fit turbo, carb and then the wiring and test

all plumbed in now hope its right
wired it up too got on/off switch just above shift switch so i can knock it off when boost up or may leave it on
just need do static tomorrow see how it goes

That just has to be insane. I'd just got to see this in action.

well just got back from a weekend at shakey.
i race in the nsa south .
saturday i was having boost prob's well not having enough but managed a 9.15 so i found i had a air leak sorted it out that night .

sunday did a run had full boost but a 1.66 60ft not the best and did a 9,38 @ 150
next it was time too turn on the bottle but never purged line and bogged off line 1.71 60ft 9.27 @ 154

so next time out i whipped the rev's up did a 1.50 60ft and got a bloody 8.75 @ 158 the 1st time in the 8's and not just in either, i'm over the moon with it
the run went as smooth as silk .

the kit is the dog's b----ks and it dose what it say's on the tin

i never had time to go again but cant wait till next meet

thanks for all your help with answers

dave

EXCELLENT!!!

Sounds good and sounds like there is more to come!

How much N2O did you use?

Thomas

not sure thomas as not weighed bottle yet . but its only a 25 hit so hope should get few runs from it .

anyone knows how many ?

dave

Hi Dave,

i was referring to HP numbers of course (don´t weigh your bottle because i don´t know how to write in english )
It would be nice if you had some more pics from your biked and engine!

Thomas

sorry grimmjar i'm using the 25hp kit


I'm now thinking about upping the jets to say 40 hp for my last meeting in October
if tev can point me on this one again would i need to knock off any timing ?
one thing I've had a worry about is my bottle position it in between swing arm and at slight angle but was thinking about cutting dip tube down and turning it upside down
any views on that too

cheers Dave

What jet NUMBERS are you using?

You shouldn't need to alter the timing on a 40 HP shot.

The bottle should be fine as it is but turning it upside down and cutting the dip tube down to 2" would be better still.

hi trev
got 30 for nos and 100 fuel its gravity

cheers dave

In that case before you step up the jets, just do a timed fuel flow test to see how much fuel you're flowing with the current jet and then repeat the process with the jet removed, then we can be sure you'll be good to run the larger jet without adding a pump.

All we need to know is how many cc's or how much weight of fuel you flow in say 10 seconds and we'll do the rest. If you choose the weight option we'll also need to know the SG of the fuel you use but failing that we can use a specimen figure to give us a reasonably accurate result.

hi trev
did test feel like a chemist now lol.
tested with jet in for 20 seconds fuel weighed 10g
tested with out jet for same time it weighed 38g

i,m using sunoco maxnos the specific gravity is 0.731

hope thats ok and thanks for your help again

dave

Yes that's all good.

If you call Ant to order the jets and tell him either to check with me or give him this info, he'll be able to work out the jet sizes needed and get them sent out to you.

cheers Trev
so no pump needed yet then

i must say your service is out standing not many companies give the support like yours,
so a very big thank you for all your help


p.s i'm at avon next month in the 8.50 class its acu you said about the nos line is that still standing if so would i be able to change over to s/steel do you supply it

all the best
dave

Happy to be of service.

Not sure what I said about the braided before but I guess it would be something along the lines that we can offer a conversion to the most suitable size of SS braid.

If you tell Ant the length of your current pipe and tell him you want a replacement dash 3 hose (with 1/8 BSP end fittings), plus 2 x Pulsoid I/L adaptors to 1/8 BSP (same fitting for Pulsoid and bottle), he'll get those sent out to you with the jets.

sorry trev never made clear enough you said i may not get through scrutineering last time i raced due to them not allowing nylon lines
or is it ok now

cheers dave

Unfortunately I don't know their current rules so the best thing to do would be to take a look on their website (assuming they have one) and if not give them a call, to be on the safe side.

well went to open sport last weekend and was running in the 8.50 class .
with the new jets fitted i did a 10.01 due to bog off line so turned up 2 step 250rpm then did a 8.79 then matched my pb 8.75 i was well happy
on the sunday i went out i was last to go in class and i ran a 8.53 bloody over the moon . i was jumping around like a mad man. and i was number 1 qualifier and thats how it stayed till monday then i got knocked out 1st round due to me not reacting quick enough and backing off at top that was a 8.86 to his 9.24 he beat me by a foot ..
not use to this drag thing sprintin just go FAST

the kit is bloody smooth as silk it's worth its weight in gold
so a BIG thanks to you all at wizard FOR ALL YOUR HELP

DAVE

Hi Dave, watched your #1 qualifying run, well done mate.
My 2nd run was my best of weekend also with a 9.82@144 in the 9.50 class, think we qualified 8th with that, which is my best so far so was well happy like you.
Am hoping to have a couple of goes at 8.50 next year, just need a change around with motors etc as my current chassis is holding me back, whereas in 8.50 i can lock rear up, wheelie bar and drag slick to get it moving off the line.
When you guys next out? Extreme performance or are you at national finals too?
