    Is that at full throttle, or just cruising around?   What fuel?  Those are BIG timing numbers if it's on boost. If thats cruising then that sounds like some real messy mapping or the remote possibility of a boost leak if it's transitioning onto boost, perhaps knock control?

     

    Very hard to speculate with so little info but sounds a bit off.

    Light cruising. So just like taking off at lights and just switching gears in proper cruise mode. At full boost it doesnt do that. Doesnt run much timing from base. like 17-18 i think but otherwise nah just light cruising. Its fkd. Makes the car shitty to drive coz of it and the fuel econo sucks big time. Ive asked the tuners and they were like thats just how it is. Pretty sure its not how it is. Running 98, highest knock value while cruising is around 4. on boost its about 20-30. Seems real conservative. 

     

    Also no bov, no leaks that i can find. Tuners either. Wil be going to a new tuner though to check out the map and see whats up with the boost. It shouldnt be maxing the afm while making no power. Makes no sense.

    I just want it to not drop timing just coz i shifted a gear. Who wants it at 8 degrees then instantly jumping into the mid 30s?? makes the car unresponsive for that split second and it gets annoying. If its normal then no worries but ive never driven a car that does that, and ive had a shit load of em so far... I found this to be quite unusual. The car also maxes out the afm at high boost.. but without the power to back it up lol 5.1v on z32.. with only 280rwkw.. i feel like something isnt quite right with the whole thing.

    So for a while ive noticed a lag in the motors response after changing gears and i started watching the hand controller to see whats up. I noticed that the timing drops out significantly before going back. Like im talking it sits around mid high 30s then ill shift gears and accelerate like normal and itll start in the high 20s then drop to like 13degs.. sometimes 8 then instantly back up to 33+. I want to know why? how do i fix this? why the hell is it even doing that in the first place??

    I'd argue that there is more to cars than how fast they go. I don't think anyone will disagree when I say the 34 interior is miles better than the 33.

    And yeah, fast and the furious has a lot to answer for now I can't afford a Supra and a GTR!!!

    Yeah even i wouldnt disagree on that.. that interior is just.. over the top with awesome hahaha still.. worth the extra 70k over a 33? nah.. i dont think it is haha

    Just seems strange the R34 GTR isn't faster or at least the same as the R33 around the ring. You would think they are nearly identical with the R34 being slightly improved. But yeah after some quick googling the times you posted are right, but i still reckon that the R33 must have had different tyres, running more boost or better driver. 29 seconds is a huge gap.

    The r33 was raced.. the r34 was literally a playstation car. Massive improvements made of the 32 because it was still heavily into motorsport whereas the r34 was not. Wasnt at lemans and the only place it did see the track was JGTC.. where it wasnt really a gtr anyway.. I guess they didnt see it needed improvements. As for tyres, they were on OEM tyres and newer tyres just keep getting better and better so the R34 wouldve had better tyres. As i was saying, ill never understand the price tag on the shittest GTR ever built..

    R33 gtr 28 seconds faster around the ring than an R34? Where did you get this information from that doesn't sound right.

     

    From the track books? R34 GTR Nur edition ran 8:28 seconds around the ring.. the R32 ran 8:21 secs. The standard are R33 ran 8:01 while the Vspec model ran 7:59 (29 seconds faster). First R35 ran 7:43 with all that new technology, better tyres, double the power just about and 10 years development from the last 33.. Pretty poor effort. 33 remains fastest skyline around the ring and currently holds the fastest drag record too of 7.10 sec 1/4 from a gtst haha

    I just got a 33.. but because performance. The chassis is better than all the other skylines. the R33 GTR is actually the fastest skyline around the ring.. by 21 secs from R32.. and 28 secs from R34.. 

    The Gtst models are about 40-50kgs heavier than a 32.. big deal. The 34 is heavier again.. Brakes are phenomenal, They look better than 34s, turn better, go faster with less power but can make plenty of power. Im running a T67 25g 8cm and its on fullboost by 3k (14psi) and makes 265rwkw on a safe tune. Going tuners next wednesday with ebc install as well. should make over 300rwkw. Currently runs 255 semis on the rear and theres nothing but traction. Doesnt spin up at all. Good chassis. Good brakes, good power. Interior is very comfy, could drive it all day without killing your back, rb25 sounds great too. What else can i say about it? haha
