i ment to include this, but what does it do? and y does it burn out with NOS...sounds like it's just to sudden boost in power that breaks it.
Thanks for the response

on any n2o systems you up the HP by changing the orfice size of the jets. Most direct port systems start with a #18 jet which relates to approx 12.5 HP per cylinder. The #21 jet will give you 18 HP per cylinder. You must also run a jet for the gas. On the 450SL we ran a separate fuel pump @ 5 psi because the car was CIS.

Nitrous is a sudden boost of power which affects mostly low end and mid-range performance. Try to avoid its use for above 6000 rpm. (What I mean is hitting the switch above 6000 rpm) I have found that to be useless. 50-60 HP of NOS on most cars will not hurt the engine except for Honda Civics SOHC 1.6L and Nissan Sentras 1.6L engines those are the ones I see throwing rods all with 50 hp.

I have never seen a german car break from a "safe" stage of n2o. I installed a 100 HP of n2o on a customers 92 M3 back in 92 and the car is still running n2o today and still posts 1/4 mile times of 12.77! Whats a better way to spend less than a $1000 and get that kind of HP? I have even n2o'd a VW beetle with a 40 hp engine! using a Sneaky Pete kit. Back then the kit was $125 and easy to hook up!

I have also used n2o in my road racing 77 VW Rabbit 1.6L. My driver posted the fastest practice time of all the sedan cars by 1 second. Which was also faster than all the qualifying times! The engine was BONE stock as how it left the factory. Suspension was modified. Just added 80HP of n2o. We could make 3 hard charging laps per bottle. It was fun blasting past the Porsches coming off the turns!

But, do I need a separate jet for the gas? With a vacuum fuel pump do they not just stop sending fuel back to the gas tank?

Where physically do you put the N2O jet on an MB V-8?

There are a few different ways to do a V8 CIS Benz.

1. Single Fogger Nozzle.
advantage= easy to install
disadvantage= Poor power/fuel distribution

2. Direct Port - 1 n2o nozzle and 1 fuel nozzle per port.
The best but time consuming to install.

3. Spray bar (long story)
advantage= easy to install

all of these you will have to take fuel from before the CIS Fuel Distributor. I use a regulator to drop the Fuel pressure down.
on the single fogger you can run a small gas jet off of the High Pressure fuel pump. Just make sure you don't exceed the max HP of the fuel pump. I think the 450SL was almost 300 hp. If you run a separate fuel pump it will have to be installed in the rear of the car and a 5/16" or 3/8" steel line brought forward.

Hey Speedtek, i tried goin to ur webpage and i got this:

I use to work for an isp called iav.com and when they got sold my account went to the new guys cowabunga computers aka http://www.smartcows.com/ and I refused to pay their ridiculous rates + they iav.com had a falling out with them.....I just need to repoint the dns when I get time. coming soon.

The NO2 molecules carry oxygen (hence the O2) and increase the density of the oxygen charge inside the cylinder. This additional O2 requires additional fuel. Once the two come together, then additioanl power is the result.

Some caveats:

1. NO2 can ONLY be used at full throttle. This means it works well with automatic trannies, but it's applications are limited to straight line running.

2. Engine internals and driveline components need to be strong, as they are highly stressed during NO2 usage. When building the V-8 for my Camaro, we used a forged steel crankshaft, forged "pink" rods that had been peened, and four bolt main caps. On the tranny, we used a furnace-brazed converter and beefy internals.

3. Refilling bottles can add up to a wallet hit if you're a power addict.

Benefits:

1. "Regular" engine performance during non-NO2 usage periods, including drivability and fuel economy.

2. Cheap initial cost.

3. Simple technology.

4. Kick ass on cars with performance reps. I've seen a Prelude that could handily run 11's all day with the squeeze. That's blistering fast for an economy-performance coupe, and will shock anyone that comes up against it.

anyone know how much it costs to refill bottles? And, do you guys think the inline 6 m103 benzes would need engine work before running 100-125hp nos? I rarely see aftermarket stuff for these cars, much less con rods and four bolt caps... How about that tranny? I heard these were rated for around 350 hp? And... do you guys think the puny rear end could handle all that power without breaking?

Last time I filled a NO2 bottle it was about $90 for a 20lb fill. That was a while ago, so might have gone up lots, or down with popularity...

wow i haven't been on this forum for a while!

your car looks JUST like mine (almost the same rims, i cannot see at that angle too closely) except I have yet to install my HID's and euros. plus I have the avantagarde grille and everything you mentioned!

was there an increase with the ignition? let me know about the NOS thing, I want it on my car as well.

e-mail me at typejr@telus.net if you have any updates!

also how is your engine bay SOOO clean? I need to repaint my headers or find some aftermarket ones

I noticed in your description of your E that you have Euro head lights with HID lighting. I have a 87 16V with Euro lights and was wondering how/what you did to get HID in there. Was it a kit? Do i need to alter the existing headlight innards? What parts do I need? Web sites? ....etc. Thanks.

Any Honda B16 that threw a rod with only a 50 shot had a bad install. I put 75 shots on stock B16s all the time and have never had one break - ever. I did six 100 shot installs on mostly stock B16s last year and they are all still running (although they have toasted a few clutches).

99% of the time when a motor gets hurt on laughing gas it is for one of two reasons:

1) Too lean
2) Wrong timing

You HAVE to add fuel if you add oxygen or your cylinder temps will go through the roof. That's why I almost always install wet kits. You guys can really simplify your lives with one as you can run a dedicated fuel line & regulator.

The other issue is ignition timing. Unless you are running a very small shot, you need to retard the timing a few degrees. What breaks the motor with bad timimg is high cylinder pressures, because the fuel is burning before the rods turn over. You CANNOT throw a rod or lift the heads unless the fuel is burning before the rod turns over. There are a variety of gadgets that will pull timing automatically when you spray. Use one.

I also recommend a window switch set to cut off right before your redline. The last thing you want to do is hit the limiter while spraying. You will instantly go lean. Then stuff breaks. The window switch can also be used to keep you from spraying at too low of an rpm. It is really nice to have.

Once you use N2O, you will pity those without it.

Hope this helps. I don't check the forum often, so feel free to e-mail questions directly.

I AM TALKING ABOUT 88-95 DX and SI SOHC engines.
92-95 Civic SI rods can tolerate 80HP.

SOHC = Single OverHead Cam

I HAVE RUN 125 HP of N20 on a lot of other Honda engines.

I won't go further on this since this is a Mercedes forum.


BTW in Hawaii a N20 refill is $45 to $50.00 retail on a 10 lbs.
I hear someplaces in California sell it by the pound for $2-3.00

80 hp per rod is 320 hp by my math. That's more than a fifty shot. Again, as I said, if they are breaking at 50, they installed it wrong.

Just responding to YOUR comments (in this Mercedes forum) about Honda motors.

I think its about $3.75/lb here. But several of my friends have nitrous pumps, so I get it REALLY cheap. Most of them run 300-500 hp fogger systems, so they go through a lot of N2O in a race weekend.
