We had a customer return us a pair of Pulsoids (that he'd bought 2nd hand), for servicing.

When they arrived it was obvious they'd been badly neglected and abused, so we were expecting the worst.

After an hour or two trying to dismantle the fuel Pulsoid (it normally takes just 5 mins), I eventually had to machine out the retainer because someone had taken it apart previously and re-assembled it using a bucket full of super strength Loctite.

Once apart it was obvious that the seat had been over adjusted and screwed up through the plunger seal which prevented the solenoid from opening and it even had the cut out section of the seat material plugging the outlet seat. Consequently fuel could never have made it's way through the Pulsoid.

ALL the internal parts needed renewing and re-testing at a cost of £70 so we were concerned that the customer would be upset at the price being so much more than the basic service price of just £25. However when we called him up to discuss the state of the Pulsoid, he informed us that he'd just destroyed his engine after using the second hand system without first having it checked and this had cost him £10,000 so another £70 was no big deal.

Now I guess he's been ripped off being charged that much, unless it was a Ferrari or something but the lesson are;

1) Why risk damaging an expensive engine buying a cheap or used nitrous kit.
2) Even if the used kit doesn't kill your engine, the difference in features that our new systems offer over our old ones, make it worth buying the new system.
3) If you must buy a used kit, at least send it to us to be serviced BEFORE you put your engine at risk by using a potentially faulty system.
4) By so doing it will cost you no more than £50 for the pair (unless they are in need of some new parts) and it could save you many 1,000s of £££s

I hope this helps others to avoid such expensive situations.

Regards

Good lesson learned there.

I can tell you that my solenoid is happily injecting away. I gave it a little demo (not wired in the boost switch) by hooking up a 12v powerpack and giving the solenoid some juice. The alloy intercooler pipe the injector is lodged in went so cold my hand almost froze to it when I tested how cool it was.

Another thing. After giving this demo my car needed to crank over for about 5 seconds to start (unlike the usual 0.25 seconds) - I think diesels don't start so well after filling up the intercooler system with nitrous. lol.

Boost switch being wired in on Saturday, so I hope to be able to use it on the road properly then.

Hi I'm new to this site and N2O.

Having bought a used WON wet kit I would definately advocate at least testing it for correct operation as I discovered my gas solenoid leaks. I'm sure most of you know the implications of gas in a non-running engine! (Manifold into outer space if you're lucky?)

Perhaps the £10 grand included compensation for the satellite he brought down?

Seriously though, why would someone skimp on a used kit and then be happy to pay £10 grand for an engine rebuild

Before you think I'm as mad as him, my car isn't worth much at all so I'm happy to take the risk once the leak has been fixed. £25 for a service is a tank full of fuel to me!
