Ha guys,

Just got back from drag wars at the motorplex ,i took my gtr up for a run to see how it would good. Its running 320hp ball bearing garett turbos, tomei cams and cam wheels,rb 20 air flow ,700cc sard injectors and apexi power fc which has put out about 518hp at the wheels at 18psi but as been tapered back a little to about 500hp. The rest is all std.

So my second trip to a drag strip every in any car i managed a

elaped time 11.332sec

terminal speed 125.17mph 201.44kph

60" 1.757

330" 4.873

660" 7.391

1000" 9.524

I felt pretty happy with this as i was having a hard time great a nice lauch two much wheel spinning and a bit of shuddering but managed consistent 1.7 60" times,is this a reasonable time for wot im running as im very new the drag strip screen as the car was aim more for track day work

p.s any advice on getting good launches

Launch style depends on what tyres, clutch and suspension you are running:cheers

clutch is a multiplate unknown brand

tyres are zr275/35/18 nittos not the r styles they use in japan

suspension std shocks and slighty lower heavy springs at best guess

ps i got a feeling one of the rear shocks could be a bit dicky (will be checking condition soon)

Good to see Peter, I assume you got George in Bunbury to finish off the tune and continue development.

1.7 is quite good for a road spec GTR running road tyres. Anything less than that will probably require extreme clutch abuse on your setup.

Ha Ken,

We did the tune at georges but i did the number crunching and cam adjustment george drove and between us we got to where we are now the tomei cam are awesome we pick up over a 100 hp just tuning them believe it or not and i am hoping to out it back on dyno soon to do further tuning but this time not for top end but for refining the rest of the map to best posible throddle responce and feel ,not that there anything wrong with it at the moment .

Ken how the gtr you got from over east going done much with it .

question for you ken i was talking with anthony i think a nice little asia guy with a r32 gtr works for sst (not 680hp anthony) he has done a single throddle body convestion on the gtr and says it improve throddle responce for him ,wot you think of the idea

If you dont mind me asking, what profile are your cams and what revs are you making max power at?

My GTR is sold to David( Bobbo) on this forum .

The guys name is Aidwin and each to there own on the conversion.

Really can't see how individual throttle plates right next to the valve are going to give a better , crisper response than one big right at one end of the manifold...

Was it done as a mod by itself or in conjunction with a few other mods at the same time?

tomei 260 9.15mm lift poncams they bolt staight in awesome cams for street and track use puts just a nice lump edge on idol (just slight) and makes 1600 plus trackable effort from at about 4600 and holds that right throught to about 7500

Was done by its self still running stock AFMs and air box, The car is so much more drivable and smoother at part throttle with out all the turbulance the 6 butterflys and shafts cause

with a nice power gain everywere. Next is remove the airboxes and meters and lots of dyno time.

12.2 with stock airboxes and turbos (1bar) and old worn stock motor with a novice driver is not bad.

Aidwin is one off SSTs apprentices and is logging every step me makes with this car and only making one change at a time.

Yeah sorry i am hopeless with names ,so wot are you driving now as the r32 gtr looked like a great buy and on the throddle body if he did anything else i'm not 100% sure but my only train of thinking was that went throddle shuts you pull a vacuvm on a much large volume so when it open your got it would pull the inishal shot very quickly over the very small volume of the std throddle body("maybe" only a thought i had last night when were talking). Anybody else tried this sort of mod out of interest.

ha steve,

novice driver i hope you didnt tell aidwin that hehe as he look to hard him self like a pro(top guy) ,i'm not sure if i'm aloud to ask this on here but wot the mod ~worth to get done as i enjoy track days etc and anything to help throddle responce is a good thing.Wot you think of the 11.33 steve running wot i am, like aidwin i battle for traction all night and i have only ever been on the strip once before.(if anyone novice its me lol)

518hprw = ~390kwrw

i think yes once you break into the tens cage and andra licence but if you ran one 10.99 i dont think they would be all over you ,more if you ran consist or depther into 10s or a high mph i think

      98 R34GTT 4k engine stumble

      By JC71 路 Posted

      forgot to mention that when it does this it does not kill the engine, but I have not kept the pedal down long enough to let it, as I see no reason to beat up on it as its got to be something simple, small and dumb causing this.  And as soon as I let off pedal, the engine returns to its normal super smooth operation and rpms re-stabilize quickly, once below 4k.

      98 R34GTT 4k engine stumble

      By JC71 路 Posted

      neither stumble or cut really seem to be an appropriate term....hard to explain its like a rev limiter but at 4k, but it violently shakes engine and entire vehicle as the rpms will not rise over 4k, even with slow acceleration. as soon as it hits 4k, it sounds like entire spark is lost entirely. plugs were 1.1 which I used as such, but later put in new plugs gapped down to .8 changed back after issue arose when I replaced the coils, still does it with either plug gap...damn and it was all running so good.

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin 路 Posted

      Oh how times have changed! I actually lean it out relative to my water/methanol injector duty cycle. The methanol adds a lot of fueling and you can then lean it out even more due to reduced knock.

      Yeah my thoughts are the same, a well thought out WMI setup, would be slightly ahead of just straight E85 and you're also chemically intercooling the charged air, dropping it even further. This is why you need to add so much more fuel as soon as you spray. I remember someone taking me through their set up before (Dennis, has a R33, lives around Cabramatta - no idea if he's still around on this forum). He would target AFR 10:1 on 98, then as WMI ramped on, AFR would lean back up to 11:1. Amazingly, he did this all through his PowerFC, a relay to cut power to his EBC solenoid if there was not enough line pressure on his WMI kit. And of course, if there wasn't any boost made above gate pressure, you wouldn't be accessing the load cells with heaps of timing for WMI. One downside to that rudimentary setup, once the WMI came on, the EBC would unleash the dragon, and of course all the timing. Tyres would fry lol.
