Just Jap Racing Posted December 7, 2011 Share Posted December 7, 2011 Hi guys, As many of you are already aware, we have been developing one of our R35 GTR's in Japan to compete in the street class of the Japanese Time Attack series. This car has been a mammoth project, engineered and built with ATTKD in Japan, sporting a VR38 stroked to 4.1 Litres, with the HKS GT-800 Twin Turbo Kit and uprated driveline, and yesterday in practice it managed a 58.6 at the Rev Speed Tsukuba Lap Battle, setting a new record for the street radial class. More details to come later, but we thought you would enjoy some updated pics of the car in its current form Cheers, Steve Just Jap Racing Link to comment https://www.sau.com.au/forums/topic/385105-just-jap-racing-time-attack-r35/ Share on other sites More sharing options...

Just Jap Racing Posted December 8, 2011 Author Share Posted December 8, 2011 that is very quick, congrats Steve. I am also interested in knowing what tyres that was on Hi Mark, We ran it on some brand new Hancook tyres we were testing out. I just corrected the time I originally posted, the actual lap time was 59.3 which as I said we are delighted with!

Roy Posted December 8, 2011 Share Posted December 8, 2011 What time does a std R35 do? I 15s or something? Big improvement Link to comment https://www.sau.com.au/forums/topic/385105-just-jap-racing-time-attack-r35/#findComment-6144133 Share on other sites More sharing options...
domino_z Posted December 8, 2011 Share Posted December 8, 2011 (edited) What time does a std R35 do? I 15s or something? Big improvement no where near that slow the 08-09 models were doing 1:01's on stock bridgestones by the best motoring crew Edited December 8, 2011 by domino_z Link to comment https://www.sau.com.au/forums/topic/385105-just-jap-racing-time-attack-r35/#findComment-6144184 Share on other sites More sharing options...
turboadam Posted December 8, 2011 Share Posted December 8, 2011 (edited) Correct me if I am wrong but that is very little improvement for such huge changes to the car. I gather that the suspension is not yet setup? <BR><BR>Also, I am curious as to why increase the displacement when getting HP out of these things is hardly difficult at std displacement.

Fair question Adam. The car is still under development and has only recently been finished so this was an early testing session, we have a long road ahead with suspension tuning, more tyre testing and a lot more. HP wise the car is also not running at full power as yet, long way to go before that happens We elected to build the car tough from the get go to ensure it was capable of making big power reliably - We are using the HKS GT-800 Turbo kit and opted to strap it to a built engine rather than stock. There will be more to come, we certainly havent seen the cars full potential as yet Watch this space!

Marlin Posted December 8, 2011 Share Posted December 8, 2011 LOL, I retract my statement. Yesterday your post stated it's done a 53.9. Hence I said THAT IS QUICK. Today your post has been altered and says 59.3. Now I have to ask, What is the hold up?

domino_z Posted December 8, 2011 Share Posted December 8, 2011 (edited) that's because the stock GTR is so good out of the box but also because tsukuba is a tight circuit - and imo the R35 has outgrown it the JDM tuners like Amuse, Mines, MCR are in the 58-9s with their square tyre setups, exhaust + ecu mods, huge aero parts hanging off the front and rear im sure you'd see a bigger margin by % on a power circuit like fuji with a big hp built motor (just as HKS have done with benchmarking their continual development car/s) Edited December 8, 2011 by domino_z Link to comment https://www.sau.com.au/forums/topic/385105-just-jap-racing-time-attack-r35/#findComment-6144273 Share on other sites More sharing options...

quiksta Posted December 8, 2011 Share Posted December 8, 2011 A bit of a random question but do the japanese take offence to the word 'Jap' written on the side of the 35? I know that some consider it an offensive slur.

Just Jap Racing Posted December 11, 2011 Author Share Posted December 11, 2011 Small update for you all, it turns out the time I originally received was incorrect and I have confirmed from ATTKD who were driving the car at Tsukuba that the car actually did a 58.6, narrowly knocking their own white R34 GTR off the top with the new record for the street radial class at this circuit. We looking forward to bring you guys more updates soon.
