As a dragracing addict i've been wondering if anybody has
been trying this cheap horsepower adder.
I'm looking for a light dose of it spraying it by a 8 nozzle
wet system wich is used a lot on carbed US V8 engines.
I'm thinking of building this nozzle set on my 55 AMG since
it's already a strongly build engine wich has some room left
in the power dept.
But the trick is in finding the right combination (nos/fuel)
of the jets.
Also will this affect the computer (check engine light) is there
a need for a extra fuelpump or is there a spot (fuelpress. schrader
valve)
I know there has been a topic on this but maybe somebody
has been experimenting after that topic.

I do recall that one post on somebody that had it.

but why are you not getting an ecu tune and headers, etc? other than the cost of course?

see my header thread link in my sig block if you haven't

I installed a NOS system on an old BMW 325 many years ago. It's surely an economic way to boos power! I used a system with combined nozzlers that has both NOS and fuel lines connected to it (+ an extra fuel pump). The installation was quite easy with just drilling and threading holes in the intake manifold and connecting the system. I had a switch on the steering wheel for the activation of the solenoids to open up the fuel/NOS. The people helping me out with the calibration of the nozzles (different size washers) told me not to use the NOS under 4000rpm and we kept the expected hp gain to around 100hp just to be sure. But what a difference it made!!!!

I used it for quite some time without any issues with the engine. I would expect the MB to also be able to cope but it's always a risk. People driving behind me at night told me the exhaust had blue flames when the nitro was activated...

Thanks for the link Nevada Joe Story is about a single fogger and gives a good boost in the power dept.
Good they mentioned the jets involved that helps a lot for starters.
And Kleemann headers are just improved logmanifolds not really a header wich improves the breathing
like a real (full lenght) header.
I used shorties on my 90s Trans Am and Z28 and these gave hardly any improvement and they where
a third of the Kleemann price and fitted without the extra welding and no computer updates nec.
The Kleemanns i need to get someone to mount them and have them welded to the stock system and
then the car has to wait until i receive my comp. back after the update (can't wait to tell the dealer
or other garage about this) .
I think the costs are header (gaskets?) 1200 e shipping 100 e working hours 400/500 e? welding 100/200?
ecu upgrade 900 (+shipping) total of 2700 e roughly for a set of shorties wich produce hardly any horsepower
i think the 25/35 horses produces according Kleemann is done by the tune (upgrade)

The car is driveable without the tune, it just will eventually throw a check engine light (mine did after a couple days) since it is missing the primary cat. So you can still drive it away from the shop without any problems, and send the ECU in while the car is at your house. It's simple enough to take the ECU out and put back in on your own.

That doesn't negate anything else you mentioned though.

Still a very expensive header set for a small increase of power
compared to a nitrous set.
Installation is also the exhaust pipe welding is more difficult for me
than installation of the nitrous sytem.
I would , if i ever go the header route get a set of full-lenghts rather
than the shorties because they are more effecient (mileage) and produce
the most horsepower in the long run.
But if prices are even higher than the shorties i think i leave it as is for the moment.
Also the nitrous installation needs a good thinking over before i start with it.
Melting pistons and sparkplugs is something wich happens quickly when things
strat to go wrong and the repairbill will be a bit higher than headers is for sure.
