Hmm that trap speed is WAY down, I was running higher than that with much lower numbers on a hub dyno - I was expecting at least 10mph more!

Good luck sussing it out, hope it's nothing to major causing the lag etc :wacko:

yer dont get me wrong the tune is no where near complete and a few other things to sort out......

wil lgo back when its done.

Its just i havent had any time at a prepared drag strip before. like i had no bogging down t mallala doing the drags but that is just a race way unprepared etc

bogging down... launch harder.. 5000+ maybe up the tyre pressure so you try and free spin and then work your tyre pressure down from there.... no need really to use antilag/ launch control free revving is fine, but if your computer has it it will assist. dont side step the cluctch either, rid it a bit aswell, this will help with your launch and also your bogging down issue :)

Missed this thread so posting a bit late.

Check your flywheel and clutch cover assembly weight, heavy is good for hard launches with sticky rubber on GTR's.

The mass assists reducing bog downs, stored energy for when you let the clutch out.

Lighter assemblies tend to head towards bogdowns.

Slicks without using anti-lag/2-step/launch control on a slightly modified turbo car is pointless ESP on a RWD or 4WD car. Your car makes no power out of boost (well slightly less than a non-turbo equivalent of your motor.) Car is not making enough power out of boost to even challenge slicks

Depends on the car and what you consider "slightly modified"

My 32 would be considered slightly modified with simple bolt ons and with Toyo TQ drag radials I got a bit carried away with launch rpm and spun all 4 and nearly ran over the Christmas tree :D

Lol that might be driver mod :rolleyes::yes: my Evo 8 with 550whp would spin all "THREE" too, not entirely sure what setups come on the GT'rs whether they have true lsd's F/R or just Rear LSD and a gripper or open lsd in front.

Slightly modded might be upgraded ECU / boost levels etc, bolt-on turbo upgrade, 3" Downpipage/3" TBE could be a multitude of other parts, but i consider that to be "slight modification"

Also to OP: Dead-hooking will and can snap axles/shear hubs/diffs I snapped my stage 3 B5 Audi S4 axles launching it off 2-step (12lbs .9bar) at the track

Edited by 350_GT

I have what you listed except turbos, still stock, yeah 3 wheels would be a better way of saying it, true machanical LSD rear with open front, heavy rear sway bar helps front traction in straight line so mine will spin all four if launched to hard :D

    • I have been being VERY quiet about what you're alluding to, as it is something that ticks me off... The number of cars from factory that run coil overs is HUGE! Most of them these days do... The other part that annoys me, is people saying "Well all the incabin adjustable suspension is illegal by blah blah blah"... If that's the case, then why can I buy a car brand new that can do it if, FULL STOP in cabin adjustable suspension is illegal...   Also, I could just chuck some aftermarket shocks in my car, throw the stock springs on, after my blue slip, dump my super low springs back in. Same shock and spring style setup... Hell, they could also be the same colour springs etc.     I'm voting, BlueSlipper didn't want to touch the above car for some reason. Whether it be some sort of bias against the car, the owner, them maybe having previously done dodgy shit and now they're being super careful in case they get slapped in the face by the Gumbyment again... Find a new blueslip place.   And can confirm as you had said, yes there are holy bibles of vehicle heights, and all sorts of other suspension stuff. Heck your run of the mill mechanic, and tyre shop has access to all of that stuff. It's how they do wheel alignments...
    • Funny story Heading to Sydney this morning on the HWY there was some slow traffic, so I gave it the beans and midway through my overtaking "power run" I lost all power It seems that I missed a hose clamp,  and the MAF and filter went WiFi To make this more problematic, the little tool kit that lives in the boot, is sitting in the sun room at Goulburn......LOL Luckily for me I found a bit of steel on the side of the road that could be used like a rusty and bent flat head screw driver to tighten it up enough that it got me into Sydney, it is now all tight like a tiger with the aid of a 8mm socket Note to self: Use my brain and double check stuff, and always keep that little tool kit in the car for when I have a brain fart
    • Oh, and as for everyone with their fuel economy changes, I switch between E10 and 98 in the company car. Even do when I had personal cars that could run on E10. You know what changed my fuel economy in any noticeable way? How I drove, and where I drove. Otherwise, say on full tanks of just back and forth from work only (So same trips, same sort of traffic), couldn't notice a difference that I can correlate to the type of fuel in use. In the current vehicle, that's over 42L of USABLE fuel. While 98 is all "more energy dense", it also has higher knock resistance as it takes more energy to get it to ignite too. The longer hydrocarbons, typically more tightly bound. So running the same ignition map, can also produce less power, if there isn't enough time to get it all burnt through properly, as yep, the flame propagation speed is different from lower octane fuel to higher (Higher has a lower flame propagation, due to the more tightly bound and harder to self ignite funs. This is also typically where, a vehicle that is designed purely to run on 91 (Whether it be E10 or normal 91) usually sees absolutely no real world difference in fuel economy for the normal man, woman, or dog.
    • We've got some servos around me that have 91 with E10, 91 (no E10), 95, and 98. At those stations the change from 91 E10 to 91, is typically around 8c/L.   But lets not get started on the price of fuel in Oz. It's ridiculous. All the service stations around me, bar one, the price of fuel has been over the $2 mark per litre for the cheapest, 98 being around $2.45. That one service station is a CostCo, fuel from it comes from the same refineries, and makes no pitstops, it runs great, including the 98. In fact, I've had no issues on CostCo fuel, but plenty of issues at other stations!. The CostCo fuel, was $1.65 roughly this week for 94 with E10. $1.88 for 98. Servos directly across from it, $2.10 for 91 E10, and $2.48 for 98. The part I had to laugh at? If I drive multiple HOURS away from Brisbane, say out near Nanango, or Kingaroy, or even out to Goondiwindi, the price of their fuel, is the same as what it is at the CostCo... Oh, and that BP servo at Goondiwindi is HUGE and goes through epic turnover of fuel, so it's not sitting there for weeks going to shit. And what blows me away, my mate is one of the people who drives the Fuel Tanker all around QLD, delivering to all those places. At the same company his previous role was doing the "local haul" deliveries... Same truck, same driver, same pickup point it all comes from. So you tell me, how the hell it is 60c/L CHEAPER for fuel, when nearly all else is equal, except they require a B-Double to drive half a day out of Brisbane, and half a day back, every second day, compared to the delivery that can be under 30 minutes drive from the fuel pickup point... Not to mention, go five blocks down the road, and Ampol to Ampol will vary 30c/L... And I've had this conversation with my mate... The way it's priced, is just typical, pure and utter rubbish... He also does runs from Brisbane, to all over QLD, down to Newcastle, Sydney, Nowra, Melbourne, Geelong, and even out to parts of the NT depending on the companies needs. His main stuff is all the longer distance away from home for a few days at a time, then when he's back, he loves to just pickup extra shifts wherever he can in whichever truck, hence all the weird different places.   Oh, as for getting E10 into all the fuels in Australia... It was very quickly highlighted, that we don't have enough biomass available to use to make E10 sustainably like they require, and it would dramatically cut into our, and the worlds food chain supply...   I vote we all just start running on liquid methane gas... Plenty of that just getting tapped off at tips from underground decay... (Note, this is pure just stupid commenting. I could very easily highlight the reasons its not a good idea especially on scale...)
    • Am I correct in assuming that the R35's are getting the classic skyline haircut off the odometer?  Quick search on carsales, there are 33 08 and 09 GTR's for sale, only 2 of them have more then 100,000km's on them (116,075 and 110,000 respectively).  And somehow there are about 25 for sale with around 60,000kms? Looks like the classic skyline haircut to me =/
