Sounds like a good deal to me as well, any more pictures of this set up?

 

so how is this different from stillen, for example?

 

I just spoke to Nick at DW. This is my 2nd phone call today with them. As you know in my first post, I spoke with Andy. He took down my number and then had Nick call me back. We spoke for a long time discussing merits of their system, and other SC kits for the 350Z.

Since it was a long phone call and a lot was discussed, I will try to cover things he told me could be discussed on a thread at this point. What I mean by that is they do not want to release data until they are 100% sure of their numbers ie hp as it will be exactly in the kit. Here is a summary:

1. Nick is confident that they will get CARB certification and the warranty I discussed in my last post. I mentioned that others talk about CARB pending but pending does not mean approved and if you are buying a street car, approved is the magic word. He really believes we will see this product in 45-90 days with the warranty and CARB approval.

2. There is a pully coming off the back of the motor. the shaft for the pulley goes through the SC housing from ft to rear.

3. He told me they have had no detonation problems what so ever and have had this motor run at 5-6000 rpm for 2 hours straight on a dyno. I did not know a motor could take 2 hours of straight dyno? He claims it is because of their dual Aux injectors, ECU flash, and fuel management system. He said the IC system they have on the kit keeps it running cool at all times.

4. He tells me the engineers that work for them now use to be the engineers for TRD/Toyota racing, specifically, the engineers that design the race cars for Toyota. Basically, he says unlike other companies entering the 350Z aftermarket, they come from racing and their products will reflect products that function for real performance on track and street.

5. After discussing the design of this SC, I realized that it kind of reminds me of the MB compressor type SC'ers.

6. Nick gave me his e-mail address. He told me that if I have any technical questions, I can just contact him again therefore, if you have questions, post them and I will get them to him & maybe he can give us some answers. Remember, the only issue is he told me he is not able to give info out that came from their R&D that other companies can apply to their systems so at some point, certain details may be withheld for that reason.

7. He said this kit would be able to be run on a track like I want to do without fear of damage to the motor. He said basically, it can go to rev limits just like the stock motor. The only thing he stressed is any motor, stock or FI, that is tracked, cannot withstand downshifting into 2nd gear instead of 4th thus exceeding redline. He said that upshifting would be safe just because the rev limiter would cut it off but the real abuse could be downshifitng and popping it into too low a gear thus causing engine damage.

Again, I hope this gives a little better picture. What a great time for 350Z's. We got so many choices coming soon and many promise to be good ones.

I hope these guys can get their car into the SportZ shoot off comparing SC/TT/NA 350's. I would love to see the Vortec and DW SC 350Z's added to the comparison right beside the exisitng 350's already booked for the shootoff such as the PE TT, Stillen SC, ATI SC, and Mossy NA car.

I just got a pm asking about warranty on the DW. I will try to describe as accurately as possible what I felt was told to me from DW concerning this issue:

If you use the SC/motor within normal limits on track/street being not over reving then it is covered. If you change the boost, components of the system including changing ECU flash then the warranty is not honored.

Basically, much like a stock Nissan, if you change the ECU rev limits, then over rev it, Nissan would not pay for it thus if you change the DW kit in ways that effect the design/performnce of it, it is not covered. I cannot be specific in every type of situation people might think up because lets face it, we are not always 100% sure when Nissan covers things on warranty (ie tire feathering & Bose) thus I can only give general examples of the DW warranty for the drivetrain. I hope this example gives you the idea of type of situations that might be covered and ones that would not be covered. Again, this is my explanation of what he told me. I hope i got it right in describing it to you.

I am just trying to give us a better picture of what we can expect from this product.

 

i like i like i like!!!

 

Wow, sounds like a nice piece of equipment. 1 question they will not be boosting 7PSI??

 

I can't wait for mine. I'm going to have to order a new clutch (not so smooth and gentle with it as it is) with this and while I'm at it, might as well get a light flywheel.

Oh God let me win the lottery and make my wife understand that I need more parts.

Wow! this sounds like the FI mod I've been looking for, will this SC kit be available for export to Australia.

Thanks

 

ZZZ-35, You will beable to buy this from any distributer who choose's to carry this piece. (performance nissan) ((shamless plug))

From my understanding it is at 5lb's boost to produce 400 to the crank. 12lb's will produce over 600.

 

600hp? bejeezus...time to get some forged 8.5:1 pistons and conrods with larger injectors and cams. Oh that would be sweet indeed. I'd have to replace the tires every month from all the blissful burnouts.

 

The Kit has the capablility to be boosted up to 12psi and those willing to void the warranty can do so of course. Think of it this way, with a warranty at 400hp at crank, without a warranty if you want more hp and boost.

My bet is it is most likely just a reliable at 7psi as other kits but they are of course going to be extra careful if they got to back it with a warrranty thus the lower 5.5 psi.

Our Z is tuned from Nissan conservatively too so that is why our ECU is programed with a wide margin of error. Some of us choose to push it a little further raising the rev limter and other vairibles to get those extra few hp. For some of you, raising the boost on the DW kit and voiding the warrranty will be something you will want to do, others would feel more comfortable keeping it at the lower psi.

 

This is the only thing that confuses me. First they say this:

Then they state this


I would have thought that once you submit a design for CARB approval you cannot then up the boost. Am I not understanding something?

 

Good observation above. It was a long phone call (40 to 60 mins is my estimate). I thought back again to everything that was said and it the best of my knowledge, both of those things were said at different times in context to what was being discussed at that moment. I did ask him again later in a different way "so you have already begun CARB testing" and he said "yes, the testing part has been done, we are waiting for approval and CARB numbers". He also said what you are saying is that the boost would not change once approved. Maybe I heard what he said slightly incorrectly or maybe they have not done more dyno testing after they submitted for CARB approval and the 400 estimated hp was prior to that point? I am sorry for the conflict in information. I assume it is my not getting my facts accurate.

If this is an issue, let me know and I will try to contact Nick for clairification.

So this kit is producing 5.5 lbs of boost. (400 crank HP) That is like 325-330 rwhp. Which sounds much like another Stillen kit? Of course both have warranties but I don't think people will pay that much for that little HP. I could be wrong but I think that is the reason more poeple don't have the stillen kit and opt to spend less and stay NA.

I personally would be interested in trading in my current ATI kit for this one if the boost could be turned up and I could retain the warranty.

 

Not an issue. The biggest issue that I have is how big is the entire unit that sets on top of the engine. It is hard to get a sense of scale from the image you posted but it looks huge! Will I still be able to remove the spark plugs without removing the blower system?

 

But DEALER warranty and Dealer install.

Thats a big difference.

 

Do we know if the warranty will be honored by dealers? I'm guessing not...

 

As stated on the bottom of their press release...

"Power-train warranty serviced by authorized Dream Works / Nissan / Infiniti Dealers."

When this comes out we will be installing / warranting this product.

 

Say I am driving the car hard or racing it (thats why people are buying it right?) and melt a piston. Will an authorized nissan dealer replace my piston?

 

I dont believe Dream Works has released any warranty specific's yet. When they do I will gladly post.

Until then I cant answer that. BUT. the warranty only covers at the 5.5lb's of boost that makes 400hp at the crank.
