Hey everyone, I was recently approaced by Pulstar Plugs to test out some new Spark Plugs for the CSRT4. I havent an idea, what Pulstars are, and I wanted to see if anyone had more knowledge about their plugs. What they are gonna do is Dyno my car as is now. Then They will add the new plugs, do their testing on the plugs, redyno and then give me my car. I will get the Plugs and Dyno Time For Free, so that is a positive. So yeah, if any of you have any additional info, let me know! Thanks Gabriel
it won't hurt to do it for the sake of doing it, but I know a few turbo guys who've tested and didn't see much on turbo cars, NA seems to be where it's at.
Waste of money. Spark plugs will not give you any HP, unless your old ones are already fuxxored. There is a big thread about these on SRTforums.
Well like I said, this stuff is for free, and i more interested in the free dyno time lol. I will IM nate and Dys about these plugs, just so i know more about em. Gabriel
Yes and I am all over that thread blackbird and I have been discussing it for some time. I ran a set of these for a little while. I noticed a few things when I did some datalogging. I noticed that I was running 3* less ignition advance with the pulstars in. I also noticed that my injector duty cycle and pulse width was lower even though I was running the same AFR. I think that may be where the increase in fuel mileage comes from (i.e. more complete burn of avaliable fuel). Not sure though since there really isn't enough data to make a reasonable conclusion. I also noticed that my EGT's were slightly higher with the plugs that with the 4306's. Personally the thing that scares me is the fact that these are platinum plugs and have a pretty high heat range. i can pretty much guess what dysphagia is gonna say. "No, don't put those in your car."
Link to the thread? knock retard? This in closed loop or WOT open loop? In closed loop if there was incomplete combustion it would cut fuel to get you to 14.7 right? Has anyone had them on a dyno? I'm askin 'cause I don't know.
Platinum should never been used in a forced induction application. Platinum electrodes retain far to much heat which is prone to cause pre-detonation. This may be why you are seeing less timing advance, have you monitored knock by chance? *edit* LOL and it looks like QUICK beat me to some of the questions.
Depends... you have everything in writing? Guaranteed repair of anything that might be damaged as a result of the test. You are present to monitor everything and you give them a minimum list of things to be monitored. You have the option of aborting the test at any instant (like if you see any signs of knock over and above the dyno with your original plugs) and having the car returned to original condition. You have the option of having your original plugs re-installed at the end. Maybe you could negotiate some stock options if they use your car in advertising?
Well here is the funny part. My knock retard stayed the same with both sets of plugs the ignition advance was the only thing that changed. All of the data logging was done at WOT in 2nd and 3rd gear. I have 2 different runs with them. First run the dyno was losing coms with the obd2 port and breaking so we think the numbers are inflated and the 2nd was on a different dyno and a slightly different setup. Lemme see if I can dig them up. Here is the link to the thread I don't post there much so I didn't get in till about page 9 or so. http://www.srtforums.com/forums/f24/new-spark-plugs-called-pulse-plugs-373031/
Just finished PMing the guy about testing my car, and he is being a twat. He wont let me watch them test my car. i told them, that if i cant watch my brand new car get tested, and you guys fuckin munk with shit, i am not down to do the testing. he then tells me, to wait to til the new car smell goes away, then bring it in. My first thought, Kiss my ass Pulstar. I told Nathan there, that all of his previous tests are on cars that of high mileage, and i am just being extra careful. I told him i just want to watch and make sure nothing crazy happens to my investment No PM's after all of that. I thought, that's real crappy of this place. seems like a fix to me. And all the dyno testing would have been on their IN HOUSE MUSTANG DYNO, which to me seems shady. I dunno, Bad deal altogether. Gabriel
Problem is you are dealing with people that have ass hairs more important to them than some mouthy douchebag in an srt-4, they will just find another to test it in, seeing as how dodge made more than 1. They don't really seem to be marketing these toward the tuner market. More toward the guys who sit there and calculate optimum rpm, throttle position, and travelling speed to maximize gas mileage on their commute to whatever nerdcock job they have.
Well, it IS their deal. Would I go for it? not a chance in hell. There is a very good chance that they don't want you to watch because if the test is not favorable to their product then they want to just keep the result private, give you your plugs and send you on your way. They might then just leave that part out of their literature that it doesn't do squat for forced induction motors. That's reasonable. Then maybe they set up the test for the most favorable results which may not resemble any normal use of the car. Not so ethical business wise. But they probably couldn't get sued for say "measured gains of xxx". Then maybe they're going to use a tuner, turn off the knock sensors, lean the chit out of it and show the power gains. And maybe just something happens during the test. Something breaks, somebody's foot slips off the clutch, whatever. And you probably have to sign a waiver to all advertising purposes of the info. So you're not going to be present, you don't have any say or idea in how they test, and you're thinking about doing this for .... a free set of plugs??? That physics, experience, and common knowledge say that, at best, won't help your motor and maybe won't hurt it??
wow i cant believe i missed this thread. ok so the pulstars are great for N/A and stock turbo cars. the higher up you climb in power output of the motor, the worse these plugs are. kingnate tested them extensively in his car and deduced that they create a mechanical timing advance of 3* in the NSRT motor. that being said, a 3* advance without computer control in a high boost motor could mean boom boom, pulstar themselves advises against putting their plugs in highly modified cars. but for most lightly modded and stock cars they work wonders. if pulstar would just spend some real money on r&d and get some serious flame propagation data along with some information being released on the timing effects recorded by various vehicles ecu's then maybe consumers could make some better decisions about their product. gabe, that is some serious bullshit that they dont want to let you witness the tests, that makes it seem like something really sketchy is going on. the inhouse mustang dyno deal seems even more out of place. did you have the same experience nate?
The one thing to take into consideration in all of this is the guy doing the testing is pretty much the premier subaru tuner in this country. Would I trust him with my car, yes, would I trust the plugs in my modified turbo car, no. Give me copper or give me death, lol.
