I had another look at the GTR yesterday. All the carbon looks amazing. Rear parcel shelf, bootlid & spoiler, bonnet/vents, engine bay, gearshift paddles, even new sport steering wheel. This Guy is the CARBON KING of South Australia!!! Very cool car.

Looking forward to hearing it under full noise out at the track. More photos Martin.........and maybe some dyno sheets?

Love to see the comparison to stock setup.

Near enough 400kw at all four wheels on our new Mainline AWD dyno at 17psi boost pressure is a nice start with a conservative tune, up from 270kw at all four stock. Thats getting close to a 50% power and matching torque improvement :D

The upgraded WR35TT turbochargers are responding nicely with excellent flat boost control, not tapering away or running out of puff at the top end like the stock pieces do. Also they will not suffer the same accelerated thrust wear and failure that the stock turbochargers do over 15psi, due to being ball bearing (no thrust bearing). So its looking nice at this stage :down:

Martin

When does the boost cut in for the new turbos? Same as the stock or a little later?

Has this affected the way the car takes off or does your car still have a little lag (if it is a ADM car) ?

Regards

Mark.

This owner could have bought a 911 or a Lambo etc, but he chose to go sick on a new R35 GTR.

Good on him. I went for a run in this car yesterday & it is awesome. Definate improvement over

my Std R35. Will look forward to going out in the country where we can stretch its legs a bit more.

Hmmm... these new turbos are looking good.

The best way of describing the response of this package is to show you the raw numbers. Attached is a dyno graph from our Mainline Chassis dyno that shows you exactly the gains vs a tune + midpipe GTR in actual percentage - the very best way of showing the comparison :)

How large is the trade off lower in the rev range given the turbo's are now larger?

I did not get to go far in this car but it did not feel much different from the bottom end.

The new ball bearing core spools up faster than the std plain bearing & this car has aftermarket

dumps that replace the primary cats so less back pressure.

To really tell the difference I would have to drive this one & then mine back to back but considering

how new this car all is I dont see that happening & I wouldn't expect to.

Going for a ride in it will be fun enough.

The boost response of these turbochargers is absolutely excellent. No doubt there is a couple of hundred rpm difference in the spool - it is impossible to avoid this when going to larger turbochargers, however the short initial gearing of the GTR and its lightning fast 'on boost' GR6 transmission effectively hide any of this to the point where the car feels like it has stock bottom end response. Where it is much different is higher in the rpm where the compressors simply dont run 'out of wind' and fall of boost like the stock items do. Most importantly being ball bearing cored there are no thrust bearings to go into rapid wear and failure mode as happens with the stock GTR turbos. My belief - and I am biased on this one so forgive me - is that the WR35TT modification is superbly matched to the GTR, adding reliability with ball bearing core design, and integrating all of the factory pleasantness of a properly integrated turbocharger solution.

As for US dealers and fitters. We have a main Willall distributor in Atlanta Georgia, that being Forged Performance, and then several dealers throughout the country. Fontana Nissan Motorsport in LA, SPE are another in Socal, in fact there are many dealers you can work with directly on the East Coast of the US that have access to Willall parts and technology :D

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
