congrats on pump gas. I know to much timing makes less H.P I believe the discussion is correct timing. so you would like him to run less timing and leaner?
maybe now I understand why YOU need colder plugs with that tune, thats a lot of heat homes.your talking about me melting something damn. you set my tune against yours I will make more torque at a colder EGT. guaranteed

 

you ever run a 9 in a street car? hp wanst my point its how often do you wanna change plugs?

 

I used to spray a stock shortblock with a 150-200 tnt shot. Probably had 200 nitrous passes on combo. It made 686 rwhp with an auto. It would still be alive if my fuel solenoid didn't fail and make it go lean.

Anyways I'm no expert but I ran the tr7 on a 150 hit and the tr8 on a 200 hit. A/F was around 11.5 and I ran 20 degrees total timming. Never hurt a plug or anything for 4 years.

Im not no expert but it worked for me.

I ran 110-116 octane in the fuel tank. I don't believe in 93 in the tank and c116 in the cell. It probalby on equals 100 octane or so.

 

How fast is your 300 shot tr6 car?
And where are the pics of your "perfect" plugs?

EGT's can lie to you, ask around. You can make heat being to rich and to lean.......They are 1980's technology buddy.

 

This was also a high compression motor 59cc head .040 gasket. I think around 11.5 comp. I know that would make a difference.

The only issue I had running a tr8 is that if I drove the car on the street I would foul plugs. I would run the tr6 on motor/tr7 on 150/tr8 on 200. It take me all of 10-15 minutes to change plugs on my ride. So it wasn't a big deal.

 

That is along the lines of what I would reccomend to someone.

 

Seemed to work. I only got to spray the 200 shot 2 times. But a would agree with atv about the setup. I would really play it safe if you want that shortblock to last. If it detenates enough it's gonna blow. Probably could have leaned it out a little on the 150 hit and gone faster. Still went pretty good 10.24 at 130mph on 150 hit 4l60e 3550 lbs.

 

LOL 9's is childs play ever go 8's in a street car rocking eminem while everyone checks it out cruising the highway? i got the vid to prove it hit up

www.glenburnieracing.com video section.

 

He was talking about a #9 plug.... cool video's

 

Tr7 plugs and pull around 6 degrees of timing to start. Then you work the timing back in the car if you have NO detonation.

Less timing and less chance of ******* something up.
Tuning is key.

 

Actually on the vid i think it was 9's in there. and the pump gas vid it was an iridium IK plug.

 

It really amazes me the people that give nitrous advise and have absolutely no clue what they are talking about.

 

So who are these people you think are we todd did ?

 

Theres more than one way to skin a cat but that doesn't mean that they are right. I'm not the best person when it come to tuning cars but generally we pull 2 degrees of timing for every 50 hp of nitrous and get one step colder plug for every 100 hp to start. Then pull plugs, check a/f and stuff like that after each run to see where we are at. So with 200hp and c-16 i'd start with 20-22 degrees of timing and tr8's for plugs imo.

 

Shiznity, you going to run pump gas drags again? Have you ever run drag week? Someone told me that there is a guy starting on a car now for 2010 drag week. Shooting for 6's.

 

just cause your too dumb to read egt and understand it doesn't make it old technology. the most advanced race cell's in the world have an egt probe in each primary, but I wouldn't expect a novice like yourself to understand that.

I don't need to upload pic's of my plugs for your amusement, and bring your 9 second car to michigan when the weather get's warm and see how fast my car is.

 

after all that talk this is all you have to say? the guy is goin up 50 hp and you want him to drop 3 heat ranges and pull 6 degrees more timing for 50 hp? but you rock to eminem on the highway in an 8 second car oooooo look at me

 

IF your currant 150 shot is spot on (would have to see a plug right after a run) i would go one step colder on plug and start with three more degrees out. so tr7 and 23 degrees. you might (after reading plugs) be able to step up to about 25 degree's on stock compression. this all depends on your car and what it likes, ive seen some bone stock cars be able to handle 3 or more degrees of timing than others so it really depends

 

Man I know I was not going to point people out when they are wrong but god sakes this could cost a motor, so thanks for doing it. I was running 18° of timing with my 200rwhp jetting, that made 235 additional dyno hp. To many people think pulling timing is going to hurt performance, not so, in reality it's the other way around. I wish i could post my lead paragraph on my site about pulling timing and spray. There are a few reasons to pull timing.

Edit: I read a little farther down, about plugs. I would not use those crappy extended tip plug TR6 on any size hit. Why everyone thinks they are such a great nitrous plug is beyond me. A true nitrous plug will not have an extended tip like the TR6. So, a TR6 may be OK for some small hits, I ran a TR7 with my 200, could you maybe. Listen to ATV and Shiz on the tuning. Just because someone didn't blow there motor with a big shot and a wrong tune, and maybe 5 passes, doesn't make it a correct tune for longevity. I get many hundreds of passes per N2O engine, so what we are saying probably works pretty well. start conservative and then you can work progressively toward a more radical tune. hell on my 300 shot 408 i am running a 13.x:1 a/f ratio, would I tell you to do that, no way, I have the rest of the tune to match (like 14° timing) and a motor that can handle an aggressive tune like that.

 

Not sure on the pump gas drags. i won it once whats the point now. maybe if i build another street car but no point with this one. atv won most legit street car on 06 so we have pretty much reached all our goals on that.

Drag week would be cool but theres alot of money and time off work involved. well do it eventually but probably not next year.
