I purchased CMCCORT's Q45 that had the NOS explosion. The car as a whole is in beautiful shape except for the part the blew up! Originally was considering it as a parts car but after getting it I think it should be kept on the road. It's in better shape cosmetically than mine and it's got a few nice mods.

Obviously it has NOS. It also has Brembo front brakes, I think the rear brakes are from a Z32 (they say nissan on them, both front and rear rotors are drilled, JWT NOS ready ECU. I also believe the fuel pump is new. Wheels and tires are in great shape. I believe the active is shot from what Cory told me.

After the explosion he said it would still start but was super rich and fuel would start coming out the intake. I think some of the fuel injectors may have been damaged from the explosion. He had already removed the plenum so I don't have any way of checking it out now. I'll have to do the plenum job and check each injector. When I went to pick it up I turned on the key to roll the window down and fuel was coming out from somewhere so we unplugged the FPCU. After I got home with it I found that at least one of the intake tubes under the plenum (pass/rear one) was full of fuel. I'm not sure what hoses he may have cut getting the plenum off so it may be coming from a hose. What are the chances of one or more of the injectors getting stuck open from the explosion? Looks to me that at least one is stuck open and when the fuel pressure comes up it is just dumping into the intake.

Well, hopefully it's just the injectors up and not damaged valves or pistons. The air box is destroyed and a bunch of vacuum tubes blew off, the plenum gaskets blew out, the hood buckled up a bit (but it bent down easily and looks pretty good now) and the grill blew off and flew into the intersection. He also said there was a small fire burning in the hood insulation when the popped the hood. The NOS nozzle looks really big, how big is the hole in the nozzle supposed to be? How do you tell what "shot" it is?

Here are some photos, sorry there are a bunch. Could be a cool project, time will tell. Won't be doing much with it yet because I need to finish my turbo project on the other Q first. They sure look cool together, they look almost exactly the same. They are both the same color.

LOL, sorry, but I just can't get that image out of my head - blew the grill off and bent the hood!



Whew, musta been quite the moment for everyone watching.

Beautiful car, though. I hope you can get it back together. As I recall, Dennis said the shot was fairly large. Here's the thread:

zerothread?id=268528

0.052 shot for 122 HP.

And for readers, here's cmccort's thread about the ... um ... mishap:

Thanks for keeping a G50 on the road.

NOS is llike coacine for cars, great little short term thrill, but what do you do when it's all gone?

Besides, takes up way too much trunk space necessary for cross country travel, let alone groceries.

Yes, it is a large NOS tank. I have a feeling that Cory maybe used the NOS a little too often. He was really having fun with it. The way he described it, it sounded like a scene from The Fast and the Furious, lol.

NOS sounds cool but I'm not too sure I'll leave it installed. I like the turbo option much better especially after seeing the carnage the NOS left in this car!

Maybe this car will get a pair of turbos..........

Nice to see a nico guy bought it. As far as the nos nozzle, what you have pictured is not the actual shot. The shot is at the end of the braided line that goes into the nozzle which goes into the throttle body.Once you get it out you will see a number on it. Let us know what number it is.And yes, run the turbo with the nos!

Maybe wes can post up if he can find the time! Thats twice Wes!

hmm. so the nozzle is between the blue spray end and the braided line? I'll pull it apart tonight and take a look.

Not sure about the suspension. Leaning towards pull it out and installing standard suspension. Not even sure what issues it has at this point. Once it's back on the road I'll have to go through it. First things first...

rick you seriously arent letting anything get by... I DID NOTHING TO YOU!!!

glad the Q stayed in the "family". Nice lookin car! I bet the reason the thing failed is the NOS solenoid needs rebuilt.

If you do decide to get rid of the NOS, hit me up. I'll get you an ECU for free if you can get me the nitrous ECU.

I'll let you know when I decide what I'm doing, like I said tho, it'll probably be a while yet. At the very least I can crack open that ECU and take some photos and pull the bin file off the chip if it's the type of chip I can use.

Are the active model ECUs different than the standard ECU w/TCS? Reason I'm asking is a while back when Cory was having issues we tried to plug in my OEM ECU (which doesn't have active) and it idled rough.

He was told the same thing when he spoke to JWT about the explosion, that the solenoid was probably in need of a rebuild. I plan to put some pressure to it and see if it leaks.

OK, so I just went out and pulled apart the nozzle and there isn't anything between the spray nozzle and the braided line. It's wide open. What shot is that! hehe. Maybe thats why Cory described it like a scene from The Fast and the Furious! lol

Maybe that's also why he was burning through NOS so fast.

If there really isn't a nitrous jet in there somewhere then watch out! My 100hp shot has a hole about the size of a paper clip diameter so no nitrous jet would probably be a 500 hp shot!!

WOW! I wonder what shot that is?If it had no shot in it that is a testimony to the VH! Wish I could have seen that. How many bottles did he go through?Maybe I should remove my shot!

hehe, that has to be why he was using up NOS so fast. He really did describe it as a huge boost. Not like I've heard you and Wes describing it as a moderate boost. He said it would really snap your neck back. There was definitely not anything in there "paper clip" diameter. The tip of that blue nozzle is the smallest opening I found. Any chance the shot is back at the solenoid?

I believe it had it partially filled several times and at least once where they were able to fill it completely.

No, that shot should be at the nozzle. My 150 shot will throw you back pretty good.But it's not insane.

Hey, I came across this cool NOS jet calculator, the link is below. I need to measure the actual diameter of that nozzle but if my guess is correct it's between 1/16-3/32" diameter. That's somewhere between .0625-.09375 According to that jet calculator that would make it somewhere between a 176-396 shot of NOS! I don't think it's quite 1/8" but if it is that would be a 705 shot! Sheesh. Even if it's only a 176 shot it's pretty amazing that motor held up.

Maybe there was no leak, maybe it just blew from the stress? What would go if that was the case? Would it have blown back into the intake or would it blow the piston or something?

Here is an online calculator from the same guyhttp://www.robietherobot.com/N...r.htm

Here's the NOS jet calculatorhttp://www.robietherobot.com/nitrous/jetcalc.zip

Interestingly, the two calculators don't give the same results and they are from the same person...

Wow.. I'm in awe. Love the picture of the grille blown off. I'm sending it to my friends.

Glad you're keeping it alive.

There has/or had to be a jet somewhere, or else he would have emptied the bottle with one pass and there is no way any stock motor could handle any more than a 200 hp shot.

I'm running a 150 shot and I get 20 runs from a 10lb bottleHe had a 20lb bottle. Plus the shot is after the solenoid.I think it could run wide open.

this is what a nitrous jet looks like



the JWT setup basically opens the fuel injectors all the way, so its very possible it held up to a 200 shot... i mean you think about it, its only 600HP for a short time. Depending on how much the timing is slammed back, it may not have detonated big time.

But HOLY CRAP NO JET? Basically running open bottle, thats SICK. I should try that sometime!!!!!!! The jet is as close to the nozzle as possible, i dont see why they would put it before the solenoid.

As far as the ECU's are concerned, the active and non active ECU's are identical, they will run just the same. the harness could have been seated improperly among other things.

It definitely didn't have anything that looked like that in the line. I can tell from that shape where it was supposed to be but it wasn't there.

Man, I wish the NOS would have kicked it when I drove it. He was still sorting it out when I got to drive it.

You know, I hate to be a meany...but...you should really know about these systems before you run one! I think I said this in another thread.

Here is a good rule...if you have not put a wrench to your Q you have nobusiness running nos! There, you have been warned,again!

Lets see a pic of that nozzle and the line where their was no jet.

Q guys are gluttons for punishment .

It's a beautiful example, and I think it's cool you still have the CA vanity tags on the car.

As another fellow "twin Q" owner, let me advise you to fight the urge to swap the good/better parts all onto 1 car. If you do that, you'll end up very happy with one and the other will become a large driveway ornament.

I was at the dragstrip with my Vette the other day, and there was a beautiful Nova there with a welded sheet aluminum intake. The Nitrous valve had not closed completely and seeped some nitrous into the intake. The guys were prepping it for a run in the paddock area. After a few minutes, the intake exploded. It sounded like a cannon. People were running for cover. It split the front of the intake. It was kinda funny to see people diving into trailers.

Nitrous is VERY volatile. Always use new solenoids and solder all your control wiring.

By the way, nice car.

The problem with vehicle Nitrous is the Sulfur Dioxide added to it to make it unsnortable, creates sulfuric acid when mixes with moisture [condensation] and eats the inside of solenoids and causes leaks.

Every 10-20 tanks I would replace the solenoids...........just an added cost to budget....................a real problem in buying using used kits.

solenoids are not expensive. Heck, the kits are only a couple hundred.At $40 a bottle=20 shots, a solenoid is a drop in the bucket. A remote bottle shut off is a must running a nitrous system. If a leak developes pressure is off system. Upon use I open my bottle at remote-after use I close the bottle with remote. Toggle is up front at hand reach along with arming switch and heater. The 150 shot is worth every bit!I'm hooked-never going back!
