Look there is a TT out... (April fools!) It's like everytime I look on this board another half-*** want-to-be company wants to make a TT for the Z. But yet there are NONE that really exist!

WTF? Makes we want to


So will someone who knows something about a real company with a real timeline please ****ing stand up?

 

Greddy and Power Enterprise both will be releasing there turbo kits in november after the sema show

 

yeah all the prototypes seem to have **disappeared**

wtf is up with that crap? .. there is supposed to be one in my area and i have heard nothing of it since it was supposed to be getting tuned 3 months ago

 

Not only the TT settup, but the skyline motor swap. Where did that go? Hell, not only TT, but single too. I remember seeing and hearing of at least 2 people doing it, but they disappeared.

 

I wonder why? It's because the kits keep blowing the VQ motors probably

 

Are you talking about the TT Jo-Tech is working on? I saw that your from the DFW area, so if thats the one then he is still working on a FMU for it. The motec they were planning on using did not work out as well as they thought.

 

What do u guys think the problem is?

Engine internals being weak, they can't figure out the fuel management or is it something else?

 

yes it was the jo-tech one (skidazzle).. seems to have disappeared since HIN.. it would be nice to have updates occasionally

 

It's Fuel management, no one can really get it right.

 

well SEMA is soon so i am counting my pennies

 

I'm really hoping someone has a solution, that hasn't been made public yet.

 

The only fix I could think of is like stillen's. I haven't heard anything bad. It would just cost alot and would require a mod to the intake plenium for additional injectors.

 

Well Stillen did the additional injector to keep cost down instead of upgrading stock injectors to larger injectors. I thought that's what I heard.

 

It's the 10.3:1 compression that's giving them the headaches !

 

I don't really think it's the compression that's giving them the headache. There are many cars out with compression like ours and higher, that are being supercharged and turbo'd and running fine, just not turning the boost up to anything crazy. It's this returnless fuel system our car uses and the ecu that's giving them a big headache.

 

Fbody LS1's don't have a return on the fuel system(run a bigger injector vs increasing line pressure). But we do have a way to change the stock ECU/PCM computer

The problems I see are no way of pulling any advance out of the timing map and can't tell the computer you have bigger injectors. Without changing those two adding boost and getting great results is going to be near impossible.

I am amazed that the engine stay together with 7 or 8 psi the ATI is showing the engine. There must be a lower octane timing map like the LS1 PCM has that it's defaulting to when the engine starts to ping. On a LS1 it's there incase the owner puts 87 in the tank or there is a mix up at the statioin and 87 is mixed with the 9X octane. A cheap failsafe in the program.

What would be interesting is to data log the spark advance for a stock Z and a blown Z for a run then compare numbers. I have always read that you take about 2* our for every pound of boost you run. Either there is room for more timing on a NA motor or something is pulling timing out on a FI car.

 

You already know I agree with you on the whole timing issue. I think there will be a solution soon enough for all of the headaches we are dealing with now. I'm sure somoene is working on it as we speak, you figure with the sales of this car, the aftermarket will be pretty big. I'm waiting on a call back from a company about the whole timing thing. I'm not sure if their product will work, it does in many other cars, but who knows with this mess.

 

maybe i missed it but since were listing all the things missing...whatever happened to the dyno day for the NA cars with over 300 whp? any results or it is still too be concluded?

 

On the returnless fuel system that we have did anyone notice that the TT kit PE is making comes with a regulator? Does this mean that on that kit we will have to install the return line? Asked Cheston but got no response. The only time you need a fuel regulator is you have a return system, so I guess that is how they fixed the bigger injector issue!! Any comments?

 

Concerning the dyno day and Richard 350Z. I met him at the willow springs track last Friday. He posted his dyno run in which at least 100 guys witnessed. A number of guys on this forum were basically crucifying him on line. All he did was post what he got on the dyno. Greg V of Mossy, whose dealer built the motor offered to have his Mossy NA car dyno'ed by the guys being so critical.

My point is that it is easy to get on line and flame guys that have taken their Z, spent thousands of dollars modifying it and paving the way for all of us by risking their warranty and investment. Every time a guy posts a dyno and modifies their car, it is educating all of us on the possibilities of the VQ. Now, the same guys that are challenging them about doing another dyno, where are they now? After guys spent maybe 3-5,000 dollars on their cars, is it the guys challenging their dyno results are not willing to put out the cost of a dyno? Maybe they can tell us.

All I know is Richard is one heck of a nice guy and now he feels like he does not want to post here too much because of how people blasted him. All he wanted to do was add hp to his car and he was excited to have such a good dyno gain. Is that a crime?

I know people want to be sure to get accurate results but I just felt like everyone was a little rough on Richard. I hope the dyno day is done, not to prove anyone right or wrong to point a finger, but just to gain knowledge of hp gain on those mods. That is why we are here, to improve all of our Z’s.

I am still debating if I want to go NA or FI. All information I learn from here helps me in that decision.
