Tardcore, I know exactly what you are talking about. It feels like everything is there, but the car just doesnt go anywhere. It doesn't just happen at 260 or 280, it starts to happen almost as soon as your cross 200. I'm pretty sure there is a VVEL map where it begins to pull back power as the temp goes up. Its extremely annoying. Car doesn't rev as fast, doesnt have the same amount of power and just falls flat on its face.

I find the best operating temperature is 180 on the dot. Anything higher than that and the car starts to lose a little umph. Oil coolers are a really important mod for this car :(

I agree completely. We all do it. We didn't buy 332 hps to never enjoy it on roads other than the track. As long as he used his discretion to make sure it wasn't life threatening to anyone, I don't think we should get on his case. We're not on an interwebz board to regulate laws and ethics. That would fail miserably.

As far as the vids go, to me, it looks like your car reacts much worse to high revs than mine. Mine eventually shoots up but nowhere near as fast as yours does in the vid. I really have to get on it for a while to get the temps up. I've yet to hit 260 and even after some canyon runs I was hovering at ~255.

Blah blah blah, we all bought this car to drive slowly at every given moment.

RCZ 02-28-2010 02:47 PM

I havent seen it go past 240-250 for months and I've driven the crap out of it. On the highway I cant get it past 190-200... not that I've tried, but it hasn't..

We all got a drivers license as a priviledge that has rules and regulations attached to it (else you lose it), one of which, as the forum rules also state, is no street racing.

:rolleyes:

Stillen is Setrab as well, almost of them are from the same manufacturer, you want to know why I know this? Yes you do, is because I am in the industry of heating and cooling things. I know the manufacturer of these coils. It doesn't matter where he gets it from they are all going to be manufactured from the same place with a different name. Odds are he got one that was pressure tested and failed and some how was painted and sent out the door.

Ummmm....Wrong problem. Tardcore had a hose blow-off. There was nothing wrong with his core.

Maybe he meant that the core caused excess pressure which, in turn, caused the hose to blow off. Have the two blown off hoses (and one broken hose) been the input to or output from the cooler?

Read the manual...it spells it out for you.

Not only that, but I'm sure the ECU is probably pulling timing as well at those temps, which would most definitely make the car feel much more sluggish.

That's probably the #1 reason. Higher IAT's = less timing advance

RCZ 03-04-2010 01:50 PM

probably? its not probably guys, that IS the reason. This car has a very aggressive tune when it comes to protecting itself from detonation.

I bought a Z after many years of driving a Camaro SS, Ls1 engine. Let's face it, the Z is not a fast car in the engine department. It's sporty, but that's about the best you can say. The car is meant for running on tight twisty canyon roads where handling and composure result in a fun drive. If you want to kick *** in a street drag race, buy a Camaro or a Stang, but don't complain about the cheap low quality interior or vague handling. Although you can mod the chassis of a Camaro and get very good handling, it will never be as good as the Z on real world roads.

Same here, although at my 1st oil change I decided to go with Motul 300V 5W-30 and I have noticed that my temps run a tad cooler and are much more stable. They do not spike when I am at WOT. Just been my experience. I will probably go with the Nissan Oil Cooler at my next oil change just to be cautious as the weather her in CA has been pretty cool since I have had my Z...

I live in San Diego as well and I always do spirited driving. I have not gone anywhere above 230 running high RPM and trust me.. when I drive.. I drive HARD. Raced s2k and Civic Si's. Never had a problem leaving them behind by a great distance. I always run VDC on (for safety purposes), I do NOT have aftermarket cooler and I do NOT have LSD since my car is base w/o sport.

I DO feel a tiny bit difference at WOT at 230 compared to 170-180, but ever since I got the INJEN Cold Air Intakes.. inside cabin has yet to warm up as it used to and Temp has yet to climb up as fast as yours.

I gotta tell you though.. there's a blue 08 or 09 Civic Si Sedan that must have at least a SC or possibly T/TT installed that lives around San Diego. Had a very rough race going home from LA on Interstate 5 a couple of months ago.. and boy that Civic can go. Never seen one of that type that had so much torque. Had to Red line every single gear (usually starting on 4th gear @80mph - puts me around 4k something RPM - WOT to red line and maybe some on 5th gear does the trick for me) and even after the shift to 6th after red lining the 5th.. the car was only about 4-5 cars back.

Some of the members here are right. Do NOT assume they are bone stock because of the way they sounded or looked. Mods such as lighter crank pulley, resonators on exhausts etc etc.. are mods that are in stealth or provides stealth and can easily make you think them cars are "bone stock" :)

im just very surprised oil coolers don't come standard on the 370. :confused:

Can you name how many cars have standard oil coolers?

Great first post lol
