This is the one they sold me, they had a bunch there at their front counter when I went for a dyno run. The girl recently asked me 'how long ago did you get this car? It still smells like new car'. It works :)

Air Spencer CS-X3 Car Air Freshener - Squash

Or maybe your car smells like a new car because it is a new car? :icon14:

Wow you are arrogant. I just recommended them, never said you had too use them but then you kept saying they were not track pads, then saying many other things. How old are you really?!

PS, do you even know what DEI is? Just curious because it sounds like you don't.

Nah it's been about 3 months now, and I've gotten into the car pretty sweaty and dirty at times working on it. The real new car small is gone. The air freshener is nice though. It's got some little adjustable vents inside it, I leave those all the way closed and you can barely notice it. Opening them makes it too strong for my taste. (and no, I didn't stick it on my dash either. I just leave it on the shelf behind the driver's seat, it seems to just kinda stay there most of the time).

Enlighten us, I don't know and google turns up lots of relevant hits actually. My top guesses from Google are an alarm system or exhaust heat-shield tape.

Design Engineering, Inc. - Thermal Chemicals DEI Radiator Relief

It's similar to Redline Water Wetter, but works better. Nissan Sport did a article on it a while back. And they sent me the product to test for them as well. I have been impressed. You guys might try it as it will lower your engine temps down a little.

Video vs Water Wetter. See how Redline foams up, not a good thing.

YouTube - DEI Radiator Relief vs. Water Wetter (Part 1)

Ah well I was close, it's the same company that makes the exhaust shielding stuff :)

Interesting, I might try it on my next flush. I have Water Wetter in there now, I'm not sure how brilliant an idea it is to mix the two.

Hmm not sure if I would mix it either. I would say just stick it out with Redline for now till you are due for a coolant flush.

Well I'm going to be flushing early anyways just to get the mix right, I've just been lazy about getting around to it. Given my location, I'd rather be running 70/30 or maybe even 80/20 -ish water/coolant anyways, plus whatever additive.

Asinine Engineering: Direct Exhaust Injection

Funny story about this btw - this was actually made up on a local board of mine in Omaha. Theres some moron on there who'd make accounts with names similar to some well-known people on the board and try to make them sound like idiots. So, they turned the tables on him and made up some fake ideas to improve performance on a motor. DEI was one of those many funny posts, and it ended up turning viral a bit haha

It became so popular, just loading the thread on the board by millions of people caused the owner of the board to surpass his bandwidth for the month, within the first week of the month alone.

Nice one :bowrofl:

Sadly, many cars come factory equipped with that form of DEI. They call it 'EGR' :shakes head: I removed the EGR system from my LS1 and put a catch can on the PCV system, makes for a cleaner intake manifold and cleaner air to burn too.

I have one in my car, I just dont list it as a mod :)

Yes I do know exactly what DEI is. I have used their exhaust wraps as well as their turbo blankets and their intake corset style shields....I just don't count wrapping my piping as an important mod that is separate from the others on the list....

Well I'm glad you removed the xpel and your radar detector from your mods...

all I said was the ds2500s were not track pads and you came out saying they are amazing and then said that after racing for 15 years you have the experience and you think they are the best you have tried....listen man...do I have to quote the stuff you said? If you want to get into it here, I will gladly get into it, but frankly I have no need to make enemies in these forums. So forget it. Nothing personal.

Same on my LS1. That was one of my first mods. Took a good 15 lbs or so off the front end :)

Right and you were incorrect. The DS2500s are considered a street/track double duty pad. The DS3000s are a dedicated track pad only.

Sigh alright. You win. Best pads ever.

Not to join your debate, but COBB was a little adventurous calling the DS2500 a track day pad for the GT-R.. it really needs more than that, and most are instantly unhappy with that compound selection for even a non-competition track day. The GT-R is a heavy car.. :)

Like I said, I have used them and many others and they work great for a street pad and when I need them for the track. I don't want to switch them out when I go to the track as they work great for that. HP+ are fade heaven.

This is a nice writeup. I like the videos as well. Def I will move out of were u living if I have to go trough all those bumps everyday :rofl2:

The track is pretty nice, I do gona comment, u gona end up without clutch if u dont trust ur car a lil on the cuves, cause going that fast and downshifting almost 3 gears all the time. Idk maybe thats why u end up without breaks. Learn the track better n ull do great.

But overwall, I love the videos and what u did so far thanks :D

Thanks for the comments. I definitely am still learning how to drive this car on that track. The gearing and torque curve are completely different than the car I used to use. I do need to trust the car a little more, I'm just so used to understeer that I don't go into the slow ones fast enough. I shouldnt have to start braking softly to keep the brakes from overheating, they should do what I want them to and if they can't handle what I need them to do, then perhaps they need to be upgraded a little bit.

I tried keeping the car in third, but the revs were dropping too much and I simply can't afford to have that happen since all those low speed corners come before straights. I do think i could keep in 3rd for turn 6 though...maybe.. I'll give it a shot next time, thanks for the advice.

Kool man, just keep practicing and I may join u down there in Miami or Homestead, wherever the place u r going. :tup:

hahahahaha

Maybe AK can clean up all the shenanigans.

Were your windows rolled down during filming?

up most of the time, cracked for a little..

Just the front rotors got destroyed? Do you think a Stoptech slotted rotor w/ better pads would be sufficient enough for you? Or do you believe a big brake kit is necessary?

RCZ and I have had some brake discussions.. at minimum a good STILLEN/DBA Pillar Vane sport rotor would help with that.. but realistically there is no reason to not go the full distance and step up to an AP Racing BBK..

I think I have him convinced.. we'll see.. :)

With a quality BBK.. stopping is just as fun as accelerating..

http://www.stillen.com/product_images/AP5700G.jpg

my vote is slotted rotors, track-specific pads, and add serious ventilation to front... stock calipers provide plenty of clamping force - that's not the issue IMO

Certainly a solution for the occasional weekender.. and the calipers on the Z are an improvement from previous years, and will hold up to some abuse taken to the track with an improved rotor and high-temp street pads.

These are not track brakes for anyone remotely serious, and will increasingly show their weakness when pushed, especially as the horsepower increase, driver comfort increases, and guys taking things a level further.

Everything is a balance to the level you want to be at, and usually ramps based upon any build, and brakes end up being one of the last modifications, despite having the most impact when truly putting them in the ultimate arena, the track.

Not the right thread or forum for this.. and I apologize.. I have access to some serious brake engineers, the ones designing brake kits, and who have immense knowledge. I'd like to make them available to you guys, and will work on doing just that. Look for some threads soon.. purely so you guys can ask the questions and get some honest info.

It would appear that the performance is finally getting to the point where the stop-factor is getting really important.. :)

Natural progression.. lol

Josh, I look forward to the data and more discussion... you speak the truth about the level of talent, from my brief conversation with one of your guys recently, I can tell that the attention to detail and experience is there... my reservation is that BBKs are a big investment and personally I need to see comparative data... for example, find a 370z equipped with traqmate or other data acquisition and do two full sessions in the same car with two different brake setups... then we can collectively look at the stopping performance, fade characteristics, etc... that's going to be the only definitive measure... as you say, the ultimate arena

Josh, you are welcome to use this thread as a discussion. I think it has run its course. If anything your parts still apply here so feel free.

You definitely have me convinced, its the $ that is getting in the way. I don't care about installation or anything for that matter. I think I'm planning on eventually turning this Z into a dedicated racer. They will be more than justified then, for right now I fall under the once or twice a month weekend racer.

man those speeed bumps are brutal!

Great to see this car getting driven to its potential....looking forward to the next steps in its progression!

You and I my friend. What happened with the tuning software from UpRev?

i hope to see something from UPREV very soon...from what i was told in the next week or so.... ;)

....Fingers crossed....

Sweet... count me in
