600C?!#@$ Where is your thermocouple placed? After the turbo? That's 1100F which is super cool. I hear the Z runs cool, but that just sounds too good to be true at 8 psi.

I am very impressed too but was also suprised by the EGT, I am glad somone else said something because I am lucky to stay under 700C and even higher. I would love 600C!

First, good job and nice numbers! I have a question. Do you have a sheet with your A/F #'s? Or can you write it down if you can't scan it. Also, do you know how much timing was taken out? Was that a specific ammonut you guys told TS to take out?

Thanks.
Bill

BOV is between the MAF and TB.

Skidazzle's car is much louder, and it has been awhile since I have driven his. Dyno numbers on low boost were put on the same chart, and shared very similar readings. We both drove each other's car on low boost, and if I remember right, clutch was different, but both OS Giken?? Skidazzle's car has open waste gates and a 3" straight pipe. Mine does not have open waste gates and Stillen exhaust has pre-silencers. It is a sleeper (quiet), but still about 4X as loud as a stock Z.

On the 20K, good guess, but just a little off.

The EGT is in the downpipe, hence the low readings. If I had it further up, the temp woul be alot higher. Probably 100C to 150C

On the timing, I do not know the specific amount, but it was quite a bit. I think Tadashi at TS is calling it the "Jotech flash". You can call him or ask Skidazzle, he may know.

I will get the a/f numbers this weekend, but they are between 10.9 and 11.8 and the line starts low, goes up and is straight acrooss... almost, but no major jumps.

Skidazzle has had a large part in helping with the car both in the design of the fuel system and his laptop for CEL's. I think we will possibly be doing a photo shoot with both cars for a magazine in the near fiture. I will let the board know when this happens.

Did I miss anything?

Thanks for the response t32 very informative. So from the looks of it there is no issue with putting the BOV between the MAF and the TB.

That's odd.... You don't have any studder or idle problems at all? Car doesn't try to die? Very odd...I know SOME cars don't mind it but some due that would be nice to know that the Z's MAF and sensor is not bothered by this..

Unless the BOV is leaking air (defective or incorrectly installed) at idle, it should have 0 effect on the idle of the car. It should have no effect whatsoever until it blows off... unless its leaking, in which case its defective or incorrectly adjusted (if its an adjustable one).

Isn't the effect during blow off just the car going to run rich? If so, is there a downside to this?

Well i know on 4g63's that if you atmospheric dump them some of them don't mind and some suffer from idle problems, sputtering, and random dying.

It has to do with the MAF reading the air going in and once the BOV vents the air to atmosphere the MAF freaks out cause it has no idea where that air is going and causes it to go into all kinds of weird modes. But when you recirculate the air the MAF is reading the same air..
Now you can fix this problem by mounting the BOV before the MAF so once the TB closes the air bounces off the TB plate, and makes it's way back through the MAF and then blows off..... Although some say that is bad on the MAF. who knows..
i personally love the sound of BOV's when the atmospheric dump

I went to Jotech today to check out the package that was put on t32gzz's Z. Man i was thouroughly impressed. Thats is an awsome car and one of the fastest Z's in the country according to Jotech. The only thing that got me was the price. $14K. I was like WOAH. 14 thousand is a lot. And that was after we went from a $1,500 dollar clutch to a $500 dollar one. I got them to match the price of the kit to that of the price on the internet which also saved a couple hundred dollars. The install price was what i expected, around $1000. What got expensive was all those little things you forget to think about.
They don't use the E-manage piggy back. They use their own fuel system. That alone runs about $2000 with parts and install. The your gages (3) at $250 a piece. Turbo timers, wide band tuning, the technosquare reflash. You guys get my point. A lot of people are seeing the $6500 price tag of the kit and are not considerring the extras to incorporate with the kit.

t32gzz, you have an great car. They were telling me to go there when u are there so i can experience it for myself. I am scared to do so because then I know I will dive in for it. I still plan on putting the kit in my car but I will have to wait for the summer. I estimated around $10K initially, so I was off by $4K. I will have to save alittle more. Here is the price quote.

First of all, chaparro78, maybe you are trying to be helpful but wouldn't you want to check with Tim before posting that?? I know a lot of time and thought went into his car and I'm not sure how appropriate it is to post something like that without asking. I know if I spent all that time and $ for a TT I wouldn't want everyone trying to do the same thing right away expecting 450 rwhp. Just my opinion, maybe Tim feels differently, but I still think you should ask.

Now for the original meaning of my post:

!!!THIS CAR IS UNREAL!!!

It all started last night, when I received a call from Tim (t32gzz)...
We talked, he showed me the dynos, we looked in the engine bay and then -

we flew!

The torque on his car is insane. With TCS on I think there was wheelspin at every shift. I say I think because I was hanging on for dear life, everything was blurry. With TCS off, it felt like we were driving on ice, and this is on 10"? wide rear tires. I can't imagine what this thing will do in the 1/4 if it can handle slicks. I could go on for hours but I won't. Jotech did an amazing job on this car and it is by far, the fastest thing on four wheels that I've ever ridden in.

Now unless you are seriously considering buying one, I would NOT recommend viewing/riding/driving a Z with the Greddy setup. On the way home, my car felt slower than walking. I made fake BOV noises at every shift, and could be heard throughout the night, humming engine noises and tires slipping.

Sorry that I couldn't add to the tech. discussion but I just had to say something. Tim, thanks for the ride. I'll probably be calling you everyday for the next ten years asking for another. I seriously think you should get the 450z custom plates to confuse everyone.

Thanks again, be safe, and enjoy it!

That was my estimate sheet i posted on here, not Tim's. This is what I plan on doing this summer. I know he has an awseome car. That is why I went to Jotech to get an estimate as to how much it was going to run me. Tim's setup is running a different clutch, has a stillen exhaust, and some other accesories.

I was in no way trying to disrespect him in anyway. I was praising te efforsts he went into building the ultimate Z machine.

All I was doing was showing people that there is more than just buing the kit and thinking that is it. There is a lot more involved.

Damn, very nice numbers. Very nice. I'd've been happy with 350 rwhp. $14k isn't bad, given what all is going into the car. Anyone interested in an Evo?

Damnnn, nice numbers. We really need to get a Dallas meet together when the weather warms up so all us NA Z's can drool over the FI Z's we now have in Dallas. Aren't we up to at least 3 by now?

$600 for the TS flash? That exactly does that do? I would pay $600 for it if it was like the DSMLink system. If I can't modify the settings of it myself it's useless. What if you want to change something? Another $600 bill? bleh.

How are you controlling the 440cc injectors if your not using the e-manage?
