Ok I'm just curious of the potential of standard turbo's for 1/4 mile racing.

Please list specs of mods WITH STANDARD TURBO'S.

me

- trust airfilters

-14psi

standard everything else

12.665

confirmed at benaraby raceway dragstrip

R33 GTR ('95) with:

- Apexi filters

- HKS front pipe

- 3'' high flow cat

- Dual N1 Apexi cat back exhaust

- 13 psi

- adj. cam gears

- standard clutch (slipping on 3rd and 4th run)

12.391 @ 107mph - Calder Park

Now have Nismo twin plate clutch, interesting to see difference

GAWD I CANNT WAIT!!!

I've already got :

HKS cat back exhaust

HKS Pods

Removed boost restrictor

Very soon I'm getting :

Power FC

Adjustable Cam gears

Inevitably at the same time I'm told a twin plate will need to replace the clutch that will turn to mash after I drive out of the tuners.

R33 GTR

HKS super Drager exhaust

HKS front pipe

HKS super power flow air filters

Apexi power fc (not tuned yet running very rich and pining very badly above 6000rpm far from ideal!)

13 psi boost

button clutch

huge custom intercooler 600x300x115 (not really needed at this power level)

Done on the worst dragstrip in australia

12.63@110mph

60ft 1.847

Personally, I ran 12.74 on stock turbos at 1 bar, air filters and Apexi GT Spec cat back exhaust and 4" Trust Drag IC. I suspect my slow time was due to running crap tyres and breaking traction all the way through 1st and second with a massive 208 Kw @ the wheels and a 60' of 2.3.

HIRISK, a regular on SAU ran 11.57 on stock GTR turbos earlier last year. Although he had other minor mods, the stock turbos held up fine.

Check out the article at http://www.fullboost.com.au/cars/featureca...tr32_shaun.html

Emre has also run 11 second runs on stock turbos with minor mods.

My 60' time was 1.850

Launched at 6500 rpm (standard clutch at the time, boy did it cop a beating that night, twin plate went in the following week coz of excessive slippage)

Running on 265/35/18 Bridgestone G'Grids

215 rwkws

Getting into 11's is not very hard and costly with GTR's... You need about 250kw at the wheels and 115mph.

I got 250kw with exhaust, cam gears and boost, everything else was stock.

Launches are very important but not tyre dependant to a great degree. I managed 1.77 and 1.73 sec. 60 foot times with Ziex's and 1.72 with Bridgestone 540's.

Theoretically yes, definitely.

You need to get the 1.7sec 60 foot and 115mph to do it in a GTR, with the same power but less weight GTS-T you should get more mph and be able to do it with a 1.8 60 footer. The trick is to nail that 60 foot and follow it with a very good run. Although i don't flat change you still have to be fairly aggressive with your gear changes. Considering we judge our cars' performance within that 0.1 of a sec. you gotta realize how clean you run has to be. Slow or missed gearchanges, loosing traction into 2nd or 3rd,hitting the rev limiter briefly will all cost you that 0.1 sec. or more that may be all the difference.

For comparison, i also did 12.1 @ 115 mph with 1.89 60 foot and 12.3 @ 115 mph with 2.05 60 foot.

    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful         
    • Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
