Don't want to start a war of arguments, just want to report what I saw at the LA Show last night.
Remember the outlandish power figures they were quoting for the car, with all the boost they were running on a 10.3 baseline compression ratio?

Well, it's no more.
The car on display had a window sticker listing all the features and the power gains.
The motor now only puts out 345HP, because they are only quoting 5.7PSI of boost. Sounds like they came to their senses on what you can do with stock compression.

Personally, to pay all that money for all that hardware and increased weight and only gain that, seems pretty stupid to me.

The car was on display downstairs, below the main floor, where all the vendors and accessory guys are.

 

345 to the wheels...thats almost 100more than stock. I think it is worth it.

 

It was the engine HP at the crank. Makes sense for 5.7PSI

 

hmmm so about 60hp... yeah that is rough. have to see how power enterprises is, otherwise good thing theres a quality shop in the area that speciallizes in nissans. have to go with a custom turbo and toss in low compression pistons while Im there.

 

Don't forget the exhaust.

 

60 to 80hp sounds about right with stock compression. I was expecting it to be closer towards 80hp though

It would be nice to see what it looks like on a dyno to see how much it raises the powerband throughout the rpm range.

 

60hp gain for twin turbo? give me a break...

NOS, here I come

 

Hard to believe that they would develop the kit on the car and then turn around and pull it all out to do a crank dyno.


I would have taken the window sticker to be at the wheels.....for only 60 hp why not go with the less expensive supercharger route. Now....100-125+ that would be a different story.

They'll easily push 5.7 psi

 

I talked to the owner of a shop in LA that works with imports and nissans a lot. He is actually working with Nissan doing R&D on head work for the 350 and also development of a street cam. His initial though based on his work with other Nissan motors was that there would be 50 to 60 whp from head work, and a good set of street cams.

Personally, I think this sounds too good to be true, but he sounded very confident since he was basing these numbers on previous work he has done with VQ motors.

The only reason I bring it up is that the increase is close to the numbers stated above, but his very gross estimate of the cost would be around $800 + install. He is planning on having real numbers in about 60 days. I will be sure to pass them along, and if he really does as well as he thinks he will, this sounds like a much more cost effective route.

The waiting is the hardest part.

 

this 345 might be where they are now... they have not upgraded the ECU, right? have they confirmed they are done with R&D on that Z kit?

They are nowhere near completion yet. Right now, they are still having issues with the fuel maps. As expected, this will be the hardest part. They also have an exhaust system in development, just for this kit. Rumor is, it could be a true dual exhaust. Don't expect to see the full potential of this kit till later this summer.

I do remember they were still trying for 400hp, which is over 100hp even if its at the crank. so we'll see what they manage.

 

Alang,

Keep us posted. 50-60 hp gain is quite impressive with just head work and cams. I wouldn't mind going this route if the expectations are achieved at that kind of price with reliability as well.

 

Is he working with the NISMO division

 

Something fishy is going on. Assuming a 15% drivetrain loss 345 crank hp is 293 rwhp. To gain 50-60 hp with a turbo is laughable! I can buy a turbo kit for my 97 maxima run 9psi safely and be around 350 front wheel hp. Now considering a stock 5-spd max dynoes in the low to mid 160's I can almost double my hp with a turbo. This can't be right.

Turbo max dyno #'s

 

You're the same guy months ago that said the entire system was a fake. Here, I pulled up your quote:

LOL, did GReddy steal your girlfriend or something?

Now, they said they weren't finished tuning the kit. Why not be patient and wait until they're done designing the setup? Unless, of course, you'd like to fabricate a twin turbo system for us?

 

He just said Nissan. I'll be going back up in a few weeks for the after mods dyno runs, I'll talk to him some more about it. What I really want to talk about is if his head work would interfere with a turbo setup in the future.

From my Z32 TT days, I remember some really impressive HP numbers from relativly low boost when a combination of bigger turbos, head work and upper and lower intake plenum work. This combination might just be the way to deal with the high compression VQ and turbos. Don't increase the boost, but increase the flow.

 

why the hell would they bother to measure the HP at the crank. I find this HIGHLY doubtful. I think it's MUCH more likely if they numbers are at the wheels.

 

I don't wanna sound like an *** but I think he's full of ****. Just got back from the LA Auto Show, the window sticker just listed the parts that were installed there was no mention of any horsepower. I tried asking one of the guys around the car and they didn't know for sure.
