it wont be the snorkel

i would be very surprised if it made 250 at one bar, but then again who knows due to the difference in dynos. anyway croat, if the engine light flashes it does mean that the power fc has picked up noise that comes up on the ping reading as (usually) 60 or more. if you have the hand controller you can check it next time, although it might have been a noise other than pinging.

i live inner city (havnt been bashed yet lol) 5min from your hotel ill show u around during the week if u like pm me.

sorry its late it does have six, (i quickly read over your post and assumed u typed six) i misread your post, they must have made a typo, as even the paragraph above the list states "you'll find factory 45mm six throttle bodies"

it does

power sounds right to me, its a gtrs not a t67 or something what do people expect, (also taking into account the level of boost)

i might get it checked out in a while, i got the car in its current tune, it feels right for what it is... it felt quite slow that day i think because of the heat... but yeah i know that other cars with similar or less mods have higher mph. i know the motor is good though as i have checked compression so it cant be that..

well i have been at oran park to watch a race once (like 4 years ago) and the corner coming onto the striaght has a well used wall that has stuck in my mind.. btw 4doorGTR im the guy from wsid with the red gtst you said hi when i turned up so hi its me

quite a coincidence i turned up and saw your ten eh.. that was the first time i had been to watch the drags at all.. (and wednesday was my second visit and first run) ill check out the videos now one just finished downloading.. thanks again for the advice, i think i will also turn up again in a few months (cant be taking time off every week!) for another run. in the meantime ill have a go at a trackday if one comes up... ps kenny, are you sure your turbos are large enough?

hey thanks heaps for your input, at least you agree on the tyre pressure with low profile issue, so now i more or less know it doesnt do anything to lower pressures on my 17s.. with 2-3mph more and say 2.1 60' i would assume a high 13, and that would be good enough for me. i am more inclined to go track racing than drag racing, so i might try on some decent 16' normal tyres but i wouldnt go as far as getting Comp TA radials... i was more going to have a go, and prove my car is good for at least a 13 rather than try and beat everyone! regarding squat, i have noticed a huge change in camber when the car squats (ie me pushing the back end down by sitting on the boot sill) so yes that would be bad i guess. btw. the last time i went to wsid a few months back i saw your car run a 10 that was impressive!

yeah a friend of mine in a 300zxtt got 100mph and 14.1 otherwise he was running very similar times to me... his car is about the same weight as a gtst. i tried dropping pressures to 23psi a few days before on the street and had a few goes, it didnt help so i guess maybe if i drop them very low like around 15. oh well i wont be going back till who knows when anyway...maybe sometime soon there will be an event in the daytime.

nah i shift fast from 1-2 and 3-4 only 2-3 was a bit slow, but trust me still pretty fast.. i think the 3rd gear synchro was having a bit of trouble keeping up which is why i couldnt get it in on previous runs.. i wish the runs at wsid were on in the day or on the weekend or something because i work on wednesday nights i had to take a night off to go, so basically i can never go unless i take nights off.... im not sure when i can go back to run a better time...

if u didnt come off you mustnt have been trying hard enough cheap tyres are cheap... but even cheap tyres become expensive when you go through them at a fast rate.... i need to get a set of 16's or something for track use.

the car i bought has a tt connected atm, i will be removing the ignition wire asap, makes things a lot easier for a thief, it looks like its drilled in though, so i guess ill have to leave the actual unit there..

hey, the car goes as it should, it feels quick driving around.. my only suspicion about tuning is about the adj cam gear, as i have heard more negative results from them than positive, it may not be set up right. other than that the car was very hot all night due to the air temps being 29-35 so all the piping etc was boiling hot in the engine bay, my MPH started at 95 and went up to 97.75 as it cooled down a bit. i also need to sort out some sort of cold air induction as the snorkel wont fit on the stock airbox because of th ic piping. also my MPH would be affected by a slowish shift into third.

thanks.. the 60' time is a main issue...maybe i could get better times if i put some 16's on and run low pressures... with that mph i was hoping for a 14.2 with a good 60" but just couldnt get it to grip hard enough. the shift from 2nd to third could have been faster 1-2 and 3-4 were fast.. still waiting to see what ben has to say about lower pressures on low profile tyres like i had fitted..

i decided im too soft for oran park, ill wait till i can have a go in wakefield, only dust to hit also im too tight to spend on tyres at the moment and im already unimpressed by my poor efforts at wsid last night. track day will have to wait.

trust me i gave it hard! only in third gear i shifted to fourth early(6600) as the power dies off at about 6500. ben, do you think dropping the pressures on low profile tyres like mine really helps? i tried dropping them to 23 the night before and launched a few times (on a private road) and there was still similar amounts of wheelspin as usual, i think the sidewalls are too stiff! * What rpm are you launching at? i tried between 2500(not quite enough) and 3500 (too much wheelspin) the best time i did was with about 3 grand * Are you doing a burnout? no burnout, only a 2 second one to clean the tyres * Do you drive the silver gst-t with bodykit and no rear wing? no i drive a red series 2 stock bodykit, the silver one from last night as far as i know had a 3 litre bottom end and lots of mods.

went to wsid last night for the first time to race Here is my best 1/4mile time: Air Temp : 29 60' 2.378 MPH 97.75 ET 14.685 i think it is to do with a couple of things: 1.crap 60' partly due to 255/40/17 tyres with very stiff sidewalls (running 38psi) 2.slow gearchange into 3rd (missed it on a previous run, did not want to risk it again) 3. it was boiling hot earlier(35 degrees) and the car was very hot, also have stock airbox with no snorkel so sucking hot air. 4. suspension not helping, i have coilovers and they dont let the car squat much. car: r33 gtst fmic 3" full exhaust exh adjust. cam gear powerfc 10psi 17" rims brass buttom clutch what do you think? i figure if i at least 2/10ths off the 60" it would drop the time to 14.2 which is still slowish i guess.

i will be there 100% look for a red r33 series 2 with light up rear skyline panel

anyone going? i am and several others are as well in the group.

got some new ones of my car ill post a few up this is from a samsung e800

as blur said make sure the car is hot when u do it, and also make sure u have a good battery connected, (battery will affect cranking speed and compression readings) outright readings are not important its more the variation, and if those readings were accurate your engine i stuffed, but its probably just the way u did the test. do it again properly and you should get some proper readings. as a guide the last compression test i did on a rb25 gave figures between 170-173psi (less than 2% difference) although as i said before dont take the outright figures too seriously.

hi, with a boost controller you will be able to bring the boost on earlier, although not by a large amount. generally speaking, there is nothing you can do if you are used to the gtst i have had two gtsts, and am often in a stockish gtr, and i know exactly what you mean about the slowness.. by the time my gtst reaches 4 grand you are accellerating pretty quickly and about to break traction, whereas you really need to keep the revs above 4 grand in the gtr to get a similar response. its normal, just fit the electronic boost controller and get used to it

Here is a couple...
