Yeah go Paul I was waiting for the come back and well done. Yep had way too hard suspension, way back with D2 we were testing, and very average and way too hard for drag racing. I would be chearing if I can run a low 10 and 9's is awesome. 25psi is a lot and how much more do you think it will run as may not boost any more than that?

Well Uncle John what did you expect...i always respond to a smart remark with a clever one.

Thanks for the "well done"

well here's a general run down of things to do

got a bit more of tuning in her (more dyno time friday night as we have nice fat low 11.1 tune in her)

got a bit more boost in her (we used to run the 2530's to 34psi...only on dyno though)

got a few more rev's in her (the 9 sec pass was done without a shift light...was shifting purely by ear and feel)

the suspension setting's have not been looked at yet (im running HKS circuit coilovers)

and ive got a nice blue bottle of spray for her too.

how's the "stealth bomber" going...im sure your tweaking something...or adding more GTR parts to it.

well done paul!!!

very nice, you could have gone a 9.999 to make it all that more special haha

are there seriously no gtr's in japan with low mounts that have run a 10?!?

Yes we have several sources over there to confirm this including well known 8sec GTR pilot Tomatsu Miyamae he says no RH9 low mount workshops or 9 sec cars. They simply bolt on the big huffers if they want to go quick. Only a stubborn Aussie (read stupid) would persist in running into the 9's with this set-up.

How is uncle Tom these days, Paulie?

And hurry the farken up and spray that biatch or John will add even more GTR parts and hunt you down!!

i would have thought that some "individual" over there would have wanted to do it

even bigger props to you...

Ran the car again at WSID yesterday....and well what a day.

I now have a very competitive racecar that i can compete with very experienced drivers.

Running the car within a 10th of a second each pass and only have to "learn" the lights a little more to start winning events.

here's the rundown

1st qualifier...stupid me forgets that the boost controller is switched off and only have 12psi of boost

60' 1.595 ET 11.064 MPH 127.35

2nd qualifier...got full boost now, its game on. Run a PB

60' 1.429 ET 9.972 (PB) MPH 138.09

3rd qualifier...run within a hundreth of a second to previous pass

60' 1.435 ET 9.985 MPH 138.76

1st round eliminator...running against an 8sec rotor on slicks and nominate 9.95 dial in. I cut a slow 0.4 light but the rotor driver completely misses the start. I have the run in the bag so back off at 1/2 track and cruise to victory.

60' 1.430 ET 10.828 MPH 91.48

2nd round eliminator...running against a 8 sec mazda with a big NOS guzzling V8 on slicks (Stewie's mate from the gong). Cut a 0.08 light and race is over by 3/4 track...another win to the GTR.

60' 1.479 ET 10.108 MPH 137.72

3rd round eliminator...running against a 2 door Valiant with another NOS fed V8 auto on slicks...very accurate car and a very experienced driver (i have to beat him on the lights). Miss the lights by 0.348 and he wins by 0.341...damn... ahh well did very well for my 1st bracket meet.

60' 1.412 (PB) ET 10.063 MPH 138.83 (PB)

A big thanks to Jim and Con from Croydon Racing for pesisting with the car on Friday night. We had intercooler hoses blowing off on the dyno and had to change all the hose clamps to keep them on. But by 9 o'clock friday night they had it all sorted. This cars results is a testament to their ability to provide us with a car that has repeatable performance. Now that they are playing more of a role with development (instead of just being our tuner) of the car, its starting to pay big dividends on raceday. Soon Jim will be fitting the Autronic ECU to enhance the performance as well as providing us with some much needed data from the runs. A two-step ignition cut launch control will see 60' times fall even further and will see the car 60'ing in the 1.3's. Only Mark Jacobsen 60's quicker than us on radials now.

Very nice. Low 1.4 second 60 footers must feel awesome.

Ohh yeah, its a bit of wheel work to keep it straight but its definately a buzz.

Blazing through the traps at 138+ MPH in the top of 3rd aint too bad either.

Yes, that is true, Adrian. But since my engine and box is being pulled out his week, I was considering my options. I also need a new front diff so this would be the opportune time to change the diff gears.

paul are you running longer gearing? or is it just the extra revs enabling you to only need to use 3rd?

Stock diff gears all round...but the OS gearset has a slightly different 3rd ratio (1.236)and is 1.302 STD...the extra revs help as well. I know that not pulling 4th keeps me under the 140 MPH mark which allows me to keep racing and not have the extra expense and hassle of getting the car fitted with a chute.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
