From what I understand you don't want to use moly rings in a nitrous application, because when it detonates (and its going to because is its inevitable with NOS) it knocks the moly off the rings which will cause compression loss and then eventually oil blow by. Then whoever told Bruce it took 3,000 miles to seat the rings is misinformed, its usually right away like in the first hours of the break in. :nono:

I'm not crazy enough to run a 300 shot but I'm thinking a 200 shot direct port with an MMS forged bottom end will make for a 9 second slip! :steering: I've already run 10.6 with their 396 all bore motor, on motor alone.
I shouldn't have gone this route.

Also not to start a fight or anything but I don't see how an NX solenoid getting stuck open is an installation issue. Seems like an NX issue to me? Be thankful it wasn't the N2O solenoid!!
The seal was damaged, torn on the inside, at the points of contact.
It was not making a tight seal.

If the N20 failed, I would have never known it, I never had NOS pressurized in the system. I am taking the system apart now for further inspection.
Thanks for your concern.

Dear Terry, I agree, I was crazy to listen to MMS in thinking their bottm end could hold up to a 300 shot..this is because they in fact are liars. As their web site states false performance claims. As they sold me on these false claims, MMS also has turned my car into re-building project.
Their workmanship on my car borderlines pathetic. Inexperience, false misleading performance claims and sloopy workmanship are their most obvious qualities
Bruce, unless you're going to give specific details or facts it seems your message is nothing more than libel.

The reason I'm pressing you is that I've personally had MMS build me 4 complete motors and I've been very satisfied with their workmanship and performance. Also I'm wondering if you haven't activated the nitrous system yet how do you know their bottom end won't hold up?

A 300 shot is a pretty serious amount of nitrous. I'm not sure how much you know about these cars and large amounts of juice, but at that level there are concerns well beyond the simple shortblock assembly. Block strength, tranny longevity, torque converter, torque tube, differential, half shafts, etc are all a major concern. I wouldn't expect to be able to make more than 10 passes on ANY 4spd auto trans at that level, and you'd probably have to pull and check your plugs after each run. Here is an example of an MMS car running only a
200 shot direct port:

http://<a href="http://www.ls1tech.c...o=&fpart=1</a>

It runs like 9.3@144. Can you imagine this with another 100hp of juice? lol! Maybe you should dial the juice back down to a reasonable 175-200hp level. Your engine may hold up to a 300 shot but I doubt your car or wallet will! :)

I really like the look of your MMS/NX system. Would you consider selling it?
I am still determined to see it operational.
But I will keep your offer in mind, thanks.

If they would have inspected this solenoid, it would have been replaced, and would have been a non-issue. The seal was damaged, torn on the inside, at the points of contact.
It was not making a tight seal.
This could only have been done while operating the system, impossible to do otherwise.
Maybe I do not understand you, but it sounds like the seal inside your solenoid was damaged? As far as I know NX will void your warranty if you open the solenoid, and I don't know of any shop that disassembles and reassembles new solenoids as standard procedure. Standard procedure is to do an operational test to ensure there are no leaks and that that solenoids are functional.

Nitrous is very volatile and things can fail at any time, which is why NO sponsors that I know of warranty nitrous motors. What was the nature of your shortblock failure in February? If something happened while on the bottle you should be _VERY_ grateful it was repaired under warranty!

After spending $14K, on this setup, I am still determined to see it operational. But it needs to be re-plumbed. I have meet with several experienced and technically advanced nitrous people here in San Diego, they have opened my eyes indeed. There are many things in my set up can be improved on.

But I will keep your offer in mind, thanks.
Thanks! The NX N2O system you have goes for around $1200 new+install, I believe. If you don't like the look of it NOS makes a pretty neat "stealthier" N2O system which goes for around $1600 new+install. You'd probably be able to keep your fuel rail covers and stuff with the NOS system.

BTW MMS did not make the N2O system; NX did. If you don't like it shouldn't you be complaining about NX?

I'm not sure what your goals with the car are, but for a complete motor, juice system, and drivetrain I don't think $14,000 is that steep at all. I've spent a lot more than that building race cars. :eek:

Maybe you can help me with some of these items that need attension.

Several alarm codes, (PCM code P-1870-hc) engine light is constantly going on. One code specifically means, I have been told that the tranny is slipping.
What is your take on that?

Terry, it burns a lot of oil. like 4 quarts in 750 miles, and sounds noisy. Does your motor use this much oil? I am concerned, I was never informed that the car would be going through this much oil.
Terry, what do you recommend?

I'm not familiar with the codes myself, but what is MMS' take? I wouldn't be surprised to find out your tranny was slipping running a 300 shot, or anything close to it, but if it were slipping you wouldn't need the PCM to tell you. Which torque converter are you running? Perhaps your PCM is interpreting your looser torque converter as tranny slippage?

Terry, it burns a lot of oil. like 4 quarts in 750 miles, and sounds noisy. Does your motor use this much oil? I am concerned, I was never informed that the car would be going through this much oil.
Terry, what do you recommend?
4 quarts per 750 miles seems high, I'd expect around 1qt per 1000 miles. How many miles do you have on the motor? Which weight oil are you using? Forged piston motors are usually a little louder than stock due to piston slap. Do you have a sound recording of the engine so I can hear for myself?

Power steering intercooler damaged, smashed, but still functions so far.
You mean the power steering cooler? Not uncommon to get it banged up a bit, I know mine was when I did some work on my old C5. I just left mine be, but they can be repaired with a radiator fin tool. I believe the cooler itself is only a $50 part.

Hood liner damage from nitrous rails installed too high.
Unsightly cut outs in plastic area at winshield wipers were added to clear the rails.
Inherent in the direct port, most guys remove the hood liner all together. Hey if running a direct port system was an easy bolt on thing everyone would have one. ;)


The Fuel line rests on the exhaust system, and gets the fuel hot in route to the motor, at the rear of the car under the back muffler area. Although the line is insulated, it is not held up off the hot exhaust pipe.
Missing bolts on the exhaust system, hanging 1/2" too low.
Burnt out 02 sensors, right bank, fried from the exhaust pipe it was resting on.
Air conditioner does not blow air into the cabin.
So you brought these problems to the attention of MMS and they refused to resolve them for you?

Actually, the installation is not complicated.
If the intake is assembled correctly, it can but put together relatively fast.

Well, because they already blew up the motor on their dyno once. This resulted in them backing off from their attempt to re-tune it for the 300 shot, per their original performance claim, a 300 performance level is what I had purchased, this is what they sold me.
What was the exact nature of the motor failure? Did one of their parts fail (like the pistons, rods, rings, heads, cam)? Or did one of your stock parts fail (like the block, main caps, stock crank, etc)?
They said they would not go there again, not tune it for 300, because if something could't stand up to the 300 shot, and failed, they did not want to replace it again, Mike said "we would have to talk." if something happened.
Ok, that gave me the creeps.
Like I said as far as I know nitrous oxide use is not covered under warranty, it sounds like he was reminding you of that. No engine builders warranty nitrous oxide use. The motor might be strong enough to handle it, but due to the volatility of nitrous in large doses anything can happen. On the same token I don't see how you bought parts you don't need. To run anything over a 175 shot you need a fuel system, direct port system, stronger motor, better exhaust, stronger transmission, and a plethora of other auxiliary parts. You buy by the part not by the HP. If only we could all get refunds because we didn't make as much power as we had hoped for. ;) Worry not though because with "only" a 225 shot I bet you have enough power to run in the 9s.

I had asked Mike to review the invoice, to lower it because of the failure to meet the 300 performance claim, he said he would look into it. The result was another $1,500 added to the bill that I had not previously authorized.
[/quote]

So if the nitrous oxide system made the 300hp performance claim, you'd be content? It's well documented that the warranty does not cover nitrous oxide use. If I were MMS I'd just try the 300 shot to make you happy and if the car melted down in the process who cares, that's your problem right? :)

Bruce here is what the MMS site says:
Looking to upgrade your tired motor? Do you want something the will stand up to a 300+shot of nitrous? Have you thought about running more boost but have been worried about putting a hole in a piston
It says this shortblock (which happens to be the least expensive shortblock they sell) uses parts that will stand up to a 300+shot of nitrous. It doesn't say your nitrous system will make 300hp if you buy this shortblock (that would be silly right?), and it doesn't say that running a 300+shot of nitrous is reliable or prudent in a street car. Again I asked specifically which part failed?

This look really impressive Terry.
But please note that it appears that MMS did not do the installation of these components, and they did not install the NOS system either. This guy is on the East Coast
It's a non local car, the customer took care of his own installation. Another lcoal MMS customer just ran 9.5@140 at Pomona yesterday. I guess they have 9 second cars coast to coast? :)

yes it does, see the write up on my car on their web site, I am a featured car:
It says":

99 - C5 - Coupe - A4
_

DESCRIPTION:
When it comes to addictions, Bruce takes his vices in the form of gas. N20 to be exact. And he has the appetite of a 70's rockstar. Sucking in 300hp at a time, your sure to see some mid 10 second time slips from this
super clean Corvette.

All this, and he still drives it on a daily basis to work.
[/B]

Again, look at the featured cars on the MMS web site.

I know MMS did not make the NX system. But they sold it to me. They assembled it, in doing so, they take on this responsibility. They cannot continue to blame their shortcomming on their suppliers, on their customers, or on the sport of racing.
I don't believe you've established any shortcomings. It sounds like you did not understand the potential complications in running a 300 shot, that you are unwilling to work with MMS to resolve the minor open issues you still have, you are unwilling to accept responsibility for the part selection that YOU made, mistakenly believe it should be common procedure to disassemble brand new nitrous solenoids, and that despite the fact that MMS repaired one motor for you under warranty even when it wasn't covered, you're ranting and raving because you can't have your 300 shot.

Just run a 225 shot and be happy. Trust me when I say your car will melt before you can even use that 300 shot you so deeply want anyway. This is what happens when you get a bunch of guys that know nothing about hot-roding trying to build race cars. ;)

The popular definition of the word vice is: "An undesirable habit". The featured car paragraph supports my position that running a 300 shot of nitrous is not reliable or prudent.
