David:

THat's the way!!! I believe that you might need stronger engine internals for higher boost, that way, you can enjoy boosting!!! But in another hand, you will need to spend further 15K or so for the parts and the labour I would say... that's a big ouch...

cheers,

What Nuff said....

Seriously also interested in both so please pm me if you don't reply in the forum.

Tks

 

David:

Are you think upgrading your brake as well?

Anyway, Stock 350z has 206kw, 280hp at the engine. (130kw at the wheels)

You saying that the APS TT kit will give you extra 140kw - 150kw at the wheels -> 280kw @ 7psi OR 70kw, 120HP at the engine ->280kw, 400HP?

I really want to see the final dyno figure before confirm about putting the TT kit. If really double the power at the wheels, $15k really a good value investment.

Cheers

 

Hi Richie, I believe that the minimum boost pressure we could run with the stock actuators (wastegate control actuators) would be approx 6 PSI.

Thanks

Peter

 

Richie, The APS TT system is being tested at the moment to see if we can meet ADR 79/00 engine emissions, if the APS TT system can meet the required emissions (and I'm confident that it will) then we will definitely release the APS TT system in Australia.

I'm not a great fan of N/A engine upgrades on small to mid size engines so I'm not the best person to ask regarding your other possible future upgrade options.

In my opinion the APS TT system at even very low boost pressure will be a far superior package to drive compared to that of a N/A package you mentioned.

I guess it all comes down to your budget and what type of power and torque you like.

I just love an engine/car that has awesome torque down low and right through the mid rpm range and then just continues making awesome power all the way through to redline.

Other guys prefer an engine which has less torque down low and needs to be reved higher through to redline to feel strong, I guess it's all about personal likes and dislikes and what you can afford.

Thanks

Peter

 

Peter,

Do you include a Bridgestone discount voucher in your kit ?

Just an idea ..

 

Just to clarify one point the power gain is relevant to increased mass air flow, not just the turbo boost pressure.

For example a large turbo has much greater mass air flow at 5 psi than a small turbo at 10psi, it's the mass air flow and fuel combusted efficiently that produces high power, at around an air fuel ratio of 12:1.

Now I believe that the APS Intercooled TT Z will produce around 270 RWkW's at approx 7 psi on our Dyno Dynamics dyno which reads approx 30 RWkW's lower than the typical American Dyno Jet dyno.

I trust this answers your question adequately.

Thanks

Peter

 

MR RIZK,

No we don't though a damn good idea.

Peter, I really interested want to know about the APS kit, what size are the turbos, compare to HKS? are they similiar to HKS2510 or 2530? Are they internal wastegate? As far as I know, anything bigger than the size of HKS2540 will require external wastegate. what band of turbos the TT kit offer?

THanks

 

LemanZ - its a Garrett M24 - go to this thread for details - https://my350z.com/forum/showthread....threadid=94368

 

The Garrett water cooled dual ball bearing turbos are produced to an APS spec (GT25/35R) and have a 32 mm bypass orifice.

All of the HKS range of turbos are produced bt Garrett though I'm not familiar with HKS part numbers..............we only use the Garrett model terminology.

The APS/Garret dual ball bearing turbos are 40 pound per minute (mass air flow) and have sufficient mass air flow to support up to 800 Horsepower.

Here's something that crossed my mind .... is the APS fitted Unichip de-speed-limited? Afterall, the 250kph limiter on the OME Zeds is not that much of an issue, but on a TT one it will be. Afterall, the APS TT Zed is supposed to hit 200kph in around 15sec, right? You can dothat in be tween every set of lights ;-)

 

There's no speed limiter on my Z so I don't see this as a problem.

Wher's the speed limiter set on the OZ model?

Peter

APS

 

Good question DavidM maybe Peter can chime in, but if memory serves me right I think Peter had the test mule only up to 140mph anyways 250kph this fast enough for the moment (on the track of couse maybe Sandown).

PS I don't think the Aussie car has a speed limiter? I maybe wrong.

Peter have you fitted the parachute to the rear of the car as request by my wife or was it ejector Recaro seats.

David

 

David I see you're still up.............oh I forgot you're 2/3 hours behind east coast time.

Your Z is coming along really nice will be on the dyno by lunch time tomorrow if all goes well

Peter

Peter try not to melt the rear muffler off the 350Z on the dyno, I love the look of that lovely shinney exhaust.

David

 

I was under the impression that the limiter was set at 250. I tried to get there once to find out but was coming up on a big truck so had to shut down. Got to 240.

 

Wher's the speed limiter set on the OZ model? ... PS I don't think the Aussie car has a speed limiter? I maybe wrong.

The limiter is supposed to be set at 250kph. Though, I can't say whether it is in the Oz models ... I pressumed that it is in all of them. I just had a quick look at SportsAuto (German) mag that also do top-speed testing, and this is what it said "250 Km/h * el. begrenzt" for the 350Z. I think that means that they got the car to 250kph, but then got stopped by the limiter.

I have not tried to go that fast myself. 210kph is fast as I've been in the Zed. Though, that makes me think - does anyone know is there somewhere in Melbourne/Vic where you can (legaly) go for top-speed runs? I know that in UK they have airport-days, where the place is closed to planes, and the cars do speed runs allong the run-way. These day are very pupular in UK and you leave with a time/speed slip kind of like at the drag-events.

I know that the local mags use Avalon for this kind of stuff us at has a 4km long run-way, but I have no idea if general public can do the same.

 

All finished David and the intercooled Twin Turbo conversion went very smoothly though took a few more hours than expected.............a few minor differences between the LHD and RHD model though nothing too serious.

I look foward to you collecting the Z and putting it through it's paces.............should feel really nice on the street...............if the Z goes as well as it looks you're going to be thrilled with the total package.

A totally built motor might cost as much as 15K but you dont need to upgrade every single part to reach the next power. Providing the fuel system can handle it if you just do the rods and pistons you will be able to up the boost and run reliably at the next level and it should cost you around AU$5000.

For Pauter rods + Rod Bolts and Arias pistons + Wrist Pins + Rings in a group buy they will cost US$1750 and to get them installed should be a couple grand at Peters here in Sydney. The clutch would also need to be upgraded which might cost another couple grand, but if you wait till the standard clutch is due to be replaced you will save a bit of money.
