R35 Faster Than Group A R32 Gtr!

[Martin Donnon]

Have a look at where the marker is on the lap plot in post #14. Like I said it feels a little 'daunting' to drive, but I have some more mods planned this week which should see the car stable at 1.4G continuous through there, and hopefully another 10km/h faster

Here is the G-Circle for the car Fungoolie. As you can see it has some grip, but it could be better!

Ahhh, so cute, a heart shaped G plot graph ))

Since you are getting up to 0.9G in left handers and 1.3ish G in right handers does that mean right handers are on camber, or it simple means that left handers are not suited for faster corner speeds??

Noooo, haha. Good work!

You're reading it the wrong way. Acceleration and braking are along the Y axis and lateral acceleration is along the X axis.

If only acceleration was along the X axis!

I would take that

I would take that

except for the fact you wouldn't be able to turn left with nearly as much speed as you could turn right

[Martin Donnon]

Designed up and fabricated a front splitter for the GTR over the past few days. Making it rigid and them mounting it properly to take force across its section was a little harder than first thought, but we have a result that should provide a good aero balance at high speed now

Pics later

Willall Racing just ran a 1 min 12.19 at Mallala today in their JDM R35 GTR.

Faster than the group A R32 GTR!

Congratulations Keir & Martin. You guys are flying now.

E85 looks like the way to go, when are you going to fit the bigger turbos?

Wish I was there................. oh well. I will keep working.

ha

[Martin Donnon]

This should balance the chassis much better at > 200km/h

[ptr]

thats a nice lip what brand is that?

[Martin Donnon]

Willall Racing brand, we designed and engineered it ourselves, and are having a small production run made over the next couple of weeks for clients that have requested them

[180or200]

sexy and practical.

[Marko R1]

but there is a massive diffrence to 40 laps at that pace and a one off

agreed - consistent times are much harder than 1 off times BUT i still want an r35

1 day...it is coming

3 sec difference so there isnt much in it

[Martin Donnon]

We arent finished yet Marko

[Martin Donnon]

New PB today testing the front Splitter and our new Braking System on the GTR

In 35 degree conditions and on a used tyre set we reset the 1:12.19 to 1:12.10.....very tight.

On a similar day to the first record we could expect to drop that time 0.5 or so. The Mallala 11s are in sight for us soon

[Martin Donnon]

In much colder conditions (where we have found it is harder to gain outright tyre grip with the GTR tyre set we use) we upped the ante again today with a 1:11.68 at Mallala, a neat improvement, and with some direction now to start steering the car towards a 1:10 second lap

[handbrake]

nice work Martin. A little birdy tells me you have trialled a new set of tyres.

dont forget my Turbos! hopefully you will have them tomorrow morning

[Martin Donnon]

Yes, yes we did run a new tyre set, however we struggle with the GTR in the cold ambients (around 10C taking into account the wind factor today, and track temp under 21C most of the day). Grip is very hard to find in these conditions, we find the GTR likes 32 - 35C ambient with the 60C track temps that it delivers. Its extremely important to set the bump and rebound rates of the suspension correctly to get the tyre working on the track to suit the conditions....we are learning more about the R35 chassis every day

[LSX-438]

interesting stuff, nice work Martin. Do you think the new tyres would have a similar proportional gain with stocker suspension?

[Marko R1]

Its not surprising that your gtr is quicker in mid 30degree than a much cooler day...it was the same when I was racing bikes, higher temp gave more grip whereas a cooler day gave more power and grip is king on the circuit
