Only problem with nitrous is the empty bottle.......

 

seems to me that a 200 shot would have been fine if done properly...

single fogger for that big of a shot is crazy though, your basically HOPING it spreads evenly through the cyl.s direct port injection is the preferred method for big n20 sprayers, and Drag knows this..


turbo, or n20, its a power adder either way, turbo's have a bigger upfront cost for power gains, but a lower maintence cost (plus 15 1/4 runs per 10lb bottle, thats running out FAST)

 

Too soon, junior.

 

So just because someone breaks something or runs nitrous they are an idiot? If I had a 35R on the car and was pushing big power and broke I wouldn't be an idiot? I'm not sure what conviced you otherwise, but the bottom line is that I pushed the limits of the motor and if there weren't guys like me out there willing to do it, then no one would ever know what the stock motor could handle. I can tell you with confidence that it will not handle over 700tq at 4000rpm If I had sprayed at 5000 or 6000rpm it would have handled it just fine. Though it appears that cyl 1 and 2 were getting most of the hp and people think I'm retarded for spraying a single nozzle, have any of you had this intake manifold on a flow bench? FWIW, all my plugs were perfect with even burn, no false reading because the car couldn't run with rods hanging out the side

The only people that don't like nitrous are guys that don't have it. Sure you can get a junk kit for $350 and start spraying and make some power, but a real good nitrous setup costs just as much as a big turbo, then you have to pump $48 every time you go to the track. It makes for a completely different driving experience and I will take a 600-700wtq instant punch in the back any day over a big turbo powerband as far as driving experience is concerned. Guys that chose nitrous didn't do it because they are cheap...there are lots of reasons. For one, show up to an auto x with a big turbo and you are done before you started. It allows you to have a multi-purpose vehicle.

I personally had it on the car for busting *** on the street and then being able to drive around cones on Sundays. That is why it was a single nozzle setup as well...real easy to hide all the spray. It looks like a bone stock car with an exhaust on it I see your 94 and 118mph in your sig...you'd be a perfect candidate for someone on the street that ended up buying me and my wife a nice dinner! I ran 95 and 119 before the hit

 

It's not uncommon for engine builders to use nitrous in the early stages of engine development to push the limits and find the weak spots on internals. It's a lot quicker and less expensive to add a 200 shot than a 37R.

I think it was focus sport IIRC that I saw talking about using just that approach with something they were working on.

Only problem is, once it fails it's often too late to figure out EXACTLY what failed.

 

When do you suspect you will finish the car?

 

This is what GM did when they were developing their ECOTEC drag race program. There are some old articles about it if you search Google. They broke a crank at 300hp and then it tells where they broke individual components at what hp levels. Pretty cool.

Everyone has been talking about these pistons breaking with boost pressures a little higher than stock and I had no such failure spraying big hits on top of high boost. People breaking pistons are too aggressive on timing. They start where the 4G makes good power and think that because this motor is more efficient that it can handle more timing....wrong direction. It requires less timing. It is clear on my motor that the rods broke, and that is all that broke.



In the next couple weeks. All last week I had to do some things to get my drag car ready for the end of the season...new dry sump, new ecu, new motor, new tranny and I'm trying to get on the dyno by Wednesday this week. So if all goes as planned, I will start putting the EVO back together next weekend. I'm still trying to decide on putting another stock shortblock back in the car or putting some nice pistons and rods in a bare block...either way it costs me the same money, just more time putting a motor together on the latter. I will post pics of everything once I get some free time. Hoping to start pulling the motor out tonight.

 

Very Impressive. Sleeve it, head Studs and put a fogger system on it

 

money to burn, nice.

 

 

Was expecting the motor to have blown itself in 2 with the title of this thread good to see even with this kind of abuse only the block was destroyed.

 

you guys seem to know what your talking about when it comes to nitrous , and i have been thinking of this for a while to see how fast i can get my slow *** gts down the 1/4 without adding turbo , so on the na 4b11 would it be a dumb idea to ad a 50 shot of nitrous , and what would be the best system to run on the na 4b11?

i dont want to boost a car that wasnt ment to be boosted id rather save my money and buy a evo , but for now i wana have some fun with what i got

 

A 50 shot isn't going to hurt anything. I like the ZEX 82021 kit. Three wires and a very clean install unlike the others with relays and loose wiring. One wire goes to your 12v switch, one to ground, and one to TPS voltage output. It doesn't get easier than that.

 

oh wow, that's wild, man! I had a customer with a similar issue last week. We were able to get him some great stuff so he can make some real power!

 

Im picking my jaw up off the table i had no idea people ran 200 shots in an evo. I have no experiance with nos but i do know that is a very large shot even for a 5.0 mustang. Impressive to see that the much smaller evo motor could handle 150 shots.
