Well I just need some help here. Well yesterday I was at the Dyno first I put a new set of plugs in TR6 then I filled up with 102. Pulled onto the dyno made 2 motor pulles not quite what I thought would happen. so I checked the car everthing seemed OK. now I turned the bottle on went to make a pull hit the n2o and within seconds I saw sparks shoting ot of the engine area so I shut down the car. went and looked and I was pouring coolant everywhere. I started to tear down the car. (good friend owns the shop so he let me do it there) pulled the plugs all of the plugs on the driver side were melted. none on the passanger side. then I pulled the head and the driver side and the head gasket blew out and blew off a piece of the head.

What I am asking is this can I just fix that problem new heads and gaskets or was there a bigger problem at hand.

also never ran lean. if there is something you need to know that might be need just ask.

 

What type of nitrous system were you using (ie; single nozzle, dual nozzle, direct port, plate)? What jetting was in the system? What fuel pressure were you running and can you find out what the pressure did when the nitrous system activated? Did you double check the wiring of everything in the system (I ask because of the "spark shooting out of the engine compartment" comment that you made)? I would think that you have a problem that isn't going to be solved just by replacing the heads, gaskets, and plugs. Without knowing more information, I would think that you got nitrous to the driver's side, but not the added fuel that is necessary. Need more info please, anything you can think of will help.

 

I am running the TNT power ring dual nozzle. jetted at 250 shot. I have made about 10 passes before with the system the same way but never on the dyno.

not shure what the fuel pressure was but I can check. also the bottle was at 950 before as well as after the run. I checked the dyno too see if I started to run lean and actually as soon as I hit the spray I became more rich.

 

Also there is a small piece of the head missing I was thinking it was the spark plug in the open atmosphere. Possible?

 

Is this a stock headed motor with stock head bolts? If so, then it could have just been that the power was lifting the head. Generally, the TNT systems will make more power than what the advertised rating is, so you were more than likely spraying more than 250hp to it. I don't see stock head gaskets and stock head bolts lasting too long with that much nitrous even with a perfect tune. The sparks you saw could have been the flame from the cylinders or red hot pieces of metal from the head or spark plugs. By chance, was there any damage to the pistons on the driver side?

 

no damage to any pistons they are forged also stock headed car with a cam. arp head bolts. I dident notice any other damage to anything.

 

With the information you given and without being there to see it, I would say that you lifted the head. I would recommend changing to studs for the heads instead of bolts, and using a high quality gasket if you aren't already. Sorry to hear about the damage, but I always look at situations like this as an opportune time to rebuild bigger and better.

 

Yea excatly what I was thinking just wanted too make shure before I put a new set of heads on and blow them away. and Im not too upset at what happend that is why I did it now too make shure before the season started.

but thanx for all the help.

 

No problem. Glad to help. Good luck with your season.

 

The sad thing is that if you are running stock Rods you never know. The odds are its ok. The car I just bought the guy had melted plugs in it before I bought it. He did a compression test and everything was alright. However the third time I drove it I was doing 40 mph and it broke a rod and spit it out of the block. So sometimes other damaged parts may not let loose until later.

there not stock rods just stock crank and block. but you never know what will happen.

 

so you melted 4 plugs??

You did put the nitrous tune it in for the nitrous pass right?

Sounds like it dentonated if you melted 4 plugs and lifted a head....

I know you're bro called me, But I have mono, so talking on the phone is like super hard, hit me up in pm or AIM or text my phone.....

 

Shouldn't you be running a step colder than the TR6 with that big of a shot?

TRMIN8R melted his TR6s with a TNT 200. I'm going TR7s for my 200...

 

yea, I think I will be running 8's when I'm ready to hit it with the big shot.... Seem like that's the norm around here...

 

maybe Ill do that Ill go too TR8 and see what happens.

 

I can't remember the name of the new head gasket, but there is reportedly a great new gasket for nitrous use. Studding and this new gasket would be a good idea, as i agree it sounds like your heads lifted. I am going to see if I can launch mine with a multi staged progressive 300 hit.

My car has GM's MLS(multi-layer Steel) head gasket. P/N# 12589226

From what I've read, that's what all the turbo guys are using that have alot of cycl. pressure. and they seem to have good results. I'll let you know how much nitrous it can withstand!!!

it will either be a headgasket or the stock shortblock!!!

 

Thats why im not a big fan of spraying on dynos, deffintly sounds like you lifted the head though........Should step up to the tr8's
good luck fixing it


4banger wasnt i just schooling you on ls1's and lifting heads last week thats why i said better safe then sorry

 

**** what that magizine says.... Don't think I'll be trying that.....

The way speed did it seems to be what is working from what I've read. Guess we'll find out soon enough...

 

I was just trying too see what it did and make shure things were in order soo I guess they werent!!
