  1. I hear what you guys are saying, but this is definitely NOT the fuel injectors. The tick that the fuel injectors make is a low audible tick and very consistent. This ticking noise is very prominent for the first 5 to 30 seconds right at start up, cold or hot. I had the hood open and put my head down to the drivers side valve cover and this ticking noise that I am referring to is coming from there. Unfortunately, it seems to be present at normal operating temp too, just not quite as loud. I have read on here where guys have had the valve lash adjusters replaced and most of them seemed to be fine after that. However, in a couple of threads that I read, the ticking noise came back after 3,000 miles or so. That is my fear/concern. So I am trying to figure out if there is something in particular that has to be done with these valve lash adjusters to keep them from being noisy, either adjustment or replacement.
  2. The car is only lightly modded. We have the TVS, FRPP shorty headers, L&M TB, & cold air kit. That's it for engine mods. We have always used the FRPP oil filters. I drove the car yesterday and I definitely heard the tick during normal operating temps. However, in order to hear it, I had to drive with the window down and be driving against a berm or a concrete divider for the sound to bounce off of, but you can easily hear it and it does get louder with increased rpm's. I think this test would probably rule out an exhaust leak, as the car was up to full operating temp, but I guess a big exhaust leak could still cause this at normal operating temps, but I really tend to lean toward the valve lash adjusters. Does anyone know anything about these on our cars or had to have them replaced?
  3. Hey guys, I have heard an engine tick on our 08 GT500, coming predominantly from the driver side bank towards the rear, especially when it is cold. This is NOT the normal fuel injector ticking, it's different and more dominant. I doubt that it is an exhaust leak, but they may be possible. I had my son start the car this morning in the garage and I popped the hood and put my head down toward the valve cover and heard the ticking very dominantly, but within 15 to 30 seconds, it softened dramatically. I do NOT know if this tick is present under normal operating temps or at higher rpm as well. My son says he has heard it when he is pulling the car back in the garage, which would mean that the tick is present even at operating temp. I have not verified this for myself yet. I have done a search on here and determined that the "engine tick" is somewhat common on our cars. In many cases people have had the hydraulic lash adjusters replaced and that fixed the problem. My concern is that I have read where a couple of guys have had these replaced and that fixed the problem, but the tick comes back several thousand miles later. At this point, I am leaning to the issue being the hydraulic lash adjusters. Are the hydraulic lash adjusters self adjusting? Is an adjustment needed to fix the problem or is it a situation where if they are noisy, the only fix is to replace them? Any thoughts?
  4. Knowing what we know right now, doesn't this seem like the late 60's all over again? What I mean is this. Most people would agree that the pinnacle year for the old muscle car era was 1970. Ford, GM and Mopar all had their highest horsepower output available that year. Then....1971 came and only Mopar had their high horsepower engines available and by 1972 those were gone. How does that relate to now. The new CAFE fuel economy standards are going into effect, I believe for either 2015 or 2016. This will cause DRAMATIC mandatory increases in fuel economy for all car manufacturers. What is coming to market now was actually on the drawing board a couple of years ago. So what will be coming to market in a few years is on the drawing board now. My point is that it feels like 1968 or so, where we are still building up to high horsepower cars, 2013 GT500, Camaro ZL1, etc. But the dark cloud is on the horizon, just like it was in the late 1960s. It seems unlikely that these high horsepower numbers will still be here come 2015 or 2016 with the mandatory new CAFE standards for fuel economy. Granted, there will still be sports cars, but will they have the incredible horsepower numbers of the 2013 GT500 or the ZL1? I personally think we are all living through a second deja vu of the late 1960s. I would suggest if you don't have one now put your plan together to get one in the next year or two, before its 1971 or 1972 all over again.
  5. We bought the MT 305/35/18 tires knowing that most people said they had good grip....but when we put the tires on the stock size rims, the negative became obvious. Unfortunately the MT 305/35/18 tires are over a half inch SHORTER than even the stock Goodyears. On a stock car, we all know how big the wheelwell seems on these cars, so having a half inch shorter tire makes the wheelwell look even worse. We have the FRPP lowering springs and the car still didn't look right. So off the tires came and Nittos went back on. The MT's never even saw the road, my son hated the look so much, that he never even drove them on the car.
  6. From what I have experienced and read, there is a massive difference between the NItto 555R's and the NT05R's. We have about 600 rwhp and the 555R's, while much better than stock, can be broken free fairly easily. However, I have read posts from several others in this power range who have gone with the NT05R's and been very pleased. It really comes down to your car's power output. A car with 600 rwhp may do great with the NT05R's, but a car with 700 rwhp may break them free.
  7. I'll say it again that all the talk about more horsepower is almost meaningless. These cars DESPERATELY need a good launch control system. It won't be the be all end all, but it would help greatly!
  8. More horsepower is great, but.......all the power in the world means absolutely nothing if it can't be planted to the ground. What I hope the engineers are working on is a GOOD launch control system for the next GT500. In a similar article elsewhere they were talking about this same thing and in that article, they said that even with all that increased power, the 0-60 time may not be any better then the current GT500, because of poor traction. If I'm not mistaken the ZR-1 has a launch control system and I'm not sure if the upcoming ZL-1 will have it, but if it doesn't then it should. Look through all of the threads on here about guys talking about this launch technique and that technique and everybody trying to figure out the absolute best rear tires, etc. I'm not saying that launch control is the be all end all, but it sure would help, ALOT.

  10. It may be the difference in rwhp, our car is a little over 600 rwhp and believe me it will spin right through 1st and even into 2nd and 3rd. We even run the PSI down around 25 on the street, the low tire pressure light is always on, but we are running less PSI to try and gain better traction with the 555R's. With the NT05R's, I have heard nothing but good things for cars at or below 600 rwhp. Several people on here say that there is no spinning from 2nd on up and depending upon rwhp and heat, little to no spinning in 1st. For 600 rwhp or less, the NT05R's seem to be a really good tire. It's just deciding on this wheel width issue.
  11. frazierfreud, thanks for the info, your analysis backs up what I have heard on the NT05R's. 2nd gear on up is great for traction, but depending upon your mods and rwhp, 1st may be a bit iffy. But that is still a huge improvement on the Nitto 555R's. Like I said I put the 555R 305/40/18 tires on my son's car and they couldn't hold in 2nd or 3rd. I think they would be good for a stock GT500, but if you are at 600+ rwhp, I just don't think the 555R's will cut it. We've just got to decide whether to put the NT05R's on the stock wheel or have them widened. Does anybody have any thoughts on the potential problems of mounting a tire on a wheel that is 1 inch narrower than the tire manufacturer recommends?
  12. Cluscher, I hear ya, but I just think that this car needs a little bit bigger tire than stock in the rear to look right. You are right that Nitto offers the NT05R in the stock size. But I would really like to have a little bit bigger tire than stock and I have heard really good things about the NT05R, it's just trying to decide whether to slap the 315/40/18 NT05R on stock wheels or have them widened. I just don't know.
  13. We debated on these tires for a long time. The concern that I had was Nitto's recommended wheel width. On their website they list the approved wheel width for this tire at 10.5 inches to 12.5 inches. Obviously the stock wheel is 9.5 inches wide. This caused me to buy the M/T 305/35/18 tires. However, these tires are only 26.4 inches tall, more than a half inch shorter than the stock Goodyears. My son hated the look of the tires, because they were so short. So before they were even driven on, the tires came off. We then simply switched back to the Nitto 555R 305/40/18. Even for these tires, Nitto recommends a 10.0 inch wide wheel, but we have them mounted on the stock size wheel and they seem to be fine. His car is a 2008 with about 600 rwhp and the traction on the 555R's is not very good. We really want to try the NT05R 315/40/18, but I am worried about the wheel width issue. What is everybody's thoughts on mounting these tires on the stock 9.5 inch wide wheel? What are the possible problems mounting them on a wheel an inch narrower than Nitto recommends? I even bought an extra set of wheels on the thought of having them widened, but that process worries me. As most people know this is a car that I had bought for my then 16 year old son who is now 19 and I would worry about him driving the car on widened wheels from a safety standpoint. By the way, the NT05R 315/40/18 tires are listed at 28.03 inches tall compared to the stock Goodyears of 27 inches tall. The height is good, the slightly taller tires help fill the huge wheel well on these cars, it's the recommended wheel width issue that I am concerned about.
  14. ULB, I'm really anxious to see some UOA's on the Redline 5w-50. I know that we have some VOA on the Redline 5W-50 on this site, but I really want to see some UOA's on that oil. All the data we can get is good, but the critical thing is the ability to compare as many UOA's as we can. This will help negate the issue of different driving styles, temps, etc.
  15. Thanks Dan, that's very good information to know! Assuming that Ford is able to follow through with this iniative, then that would certainly decrease some of the engine rebuild concerns. I just hope this doesn't turn out to be the Vega engine from the late 60's, early 70's. I wasn't there, but I've read about it. Apparently, Chevrolet had designed a new technology that would allow them to build aluminum blocks without the use of iron sleeves. Things went terribly wrong and Chevrolet ended up abandoning the entire engine program, and went back to iron blocks. Quite obviously, technology has come along way since then, I just hope for future car collector's sake that the PWTA process takes hold in the automotive industry and the future rebuilding of these engines ends up being relatively simple. Does anybody know if there are any other automotive engines that are currently using the PWTA process?
