i would hope so. it was my first ever launch in the car so theres more to come with practice.

What tyres have u got? Reckon a set of -888's would make grip a bit better and improve ya 60ft remarksbaily (sp?)

there falken 265/35/18 all round. there virtually brand new aswell came on the car when i bought it.

ive just been reading through the book some more and they talk of shallow staging like you can do at a proper drag strip, so you get up to 12 inches of tyre roll before the clock starts, ive eliminated that with 0 inches aloud for staging so technically i think i should have it accurate. they mention pitch adjustment aswell but apparently i will have to run at a drag strip and compare to set that, ive set it so as i get no advantage for better accuracy.

scoooby slayer

iTrader: (4)

well the pitch correction factor seems to be about right as they say 2d for each g of acceleration, and my peak g is 1.

scoooby slayer

iTrader: (4)

thats awesome mate, i assume that was all grip and not wheelspinning

RickyLee53

I'd say it'd do a low 11 high 10 if a perfect run going on the 128mph terminal you got on 1 run.

I wonder how accurate these devices are, anybody ran 1 at pod? To see what they show?

Regards

red r racing in nz reckons hes within 1 or 2 tenths and 1 or 2 mph at the strip.

this is the vid i found of testing it

That was spinning all 4 through 1st gear and a bit in 2nd, its an arse to launch mine, you have 2 choices, bog it down or spin all 4(well, 3 technically)!
Its not ridiculous sit on the spot wheel spin though, so it doesn't loose me much time i dont think!

We tested one against the ultra accurate Datron timing gear. The Gtech was fairly accurate, but was up to half a second out at 100. It was also affected depending how you drive - it was less accurate if you were aggressive and very jerky.

It's a laugh, but it's not something you can rely on as gospel.

Edit: just seen how much the Gtech is!!! That's the same as a Racelogic Performance box!!

scoooby slayer

iTrader: (4)

i done my research before purchase and it seems the results are pretty easy to exagerate. its certainly close enough for my use anyways.
the biggest innacuracy is the start with this rollout staging part that ive eliminated completeley to make it as accurate as possible.
roads need to be flat and needs to be a straight pull as pulling left or right will give exagerated readings due to the gs.
used properly in proper condition they are within 2 tenths and 2 mph so i am led to believe.
and also pitch factor, i am going to pod this year and will run the gtech on my run and compare to make sure it set up correctly.
im not trying to break any world records so 2 tenths of a second and 2 mph is feck all to me.

Jay,

iTrader: (4)

there all shit lol cant beat proper timing gear

DanW@FastFord

iTrader: (1)

Why didn't you buy a Performance box? Very accurate and the same price?

Rick

any time you save on the 60ft can usually be doubled at the end, so you have a very low 11 in there.

scoooby slayer

iTrader: (4)

i can understand this fully when trying to break records, they are accurate enough for what i want.

scoooby slayer

iTrader: (4)

i have seen results where the performance box has given another 10th over the gtech. as far as i understand it there much the same but i prefer the layout of the gtech. the accuracy is in the opperator imo. i could make the gtech show a 10 second 1/4 i think by shallow staging on a 16" rollout but whats the point.

the 1/4 mile side is a bonus as are all the features becasue in truth i bought it for an accurate 30 - 130 mph time which it gives me as the start is eliminated from this equation.

scoooby slayer

iTrader: (4)

which is about right for the spec, so ive read on the forums on a perfect run it should be an 11 something second car.

DanW@FastFord

iTrader: (1)

The PB is GPS based and very accurate though? The GTech is a 'bit of fun'. Just seems an odd choice to go for the least accurate one. Not trying to cause an argument or anything, just curious really.

scoooby slayer

iTrader: (4)

no mate its all good

i guess the gps is less susceptable to innaccuracy but the inaccuracys of the gtech are down to operator error. i just like it, the software is cool.

with a gps if you cant get signal (which is an issue i have with my tom tom and road angel where i live) they will not work.

just my personal preference mate.

Jay,

iTrader: (4)

thats my point karl the g tech is just a gimmick i find it strange that your a clever bloke buying tat the arse dyno always wins

DanW@FastFord

iTrader: (1)

I wouldn't say it's 'tat' Jay. It's a fun little gadget. Just a rather expensive fun little gadget

scoooby slayer

iTrader: (4)

lol i wouldnt take any of the meters gtech or performance box as gospel to within 0.1 of a second, there all a muchness imo near enough for the mear mortel. tbh imo i think it would take ££££ worth of gear to guarantee every 0.1 of a second.

and anyways that gtst wouldnt have enough oooummph to be worth having a performance meter in it lol

scoooby slayer

iTrader: (4)

i cant agree on that mate a gadget is to weak a word for it imo. as ive said im not that anal to expect 0.1 mph accuracy especially not for £250.
for an enthusiast like myself the gtech or performance box are more than ampel.

Jay,

iTrader: (4)

i guarantee its about as accurate as a blind man playing darts

depends what ur oooooummph means imo straight line speed means fuckall to me karl track is my thing now so 600 bhp is useless if you cant get it down and a 300 bhp 1976 lotus sunbeam can lap quicker so ill save my £250 for slicks

but if it makes you happy mate its all good

scoooby slayer

iTrader: (4)

well ive just read a test report for the performance box and gtech and fair does the performance box was within 1 tenth whereas gtech was within 2 tenths.
but more interestingly with using 0 rollout like i have the 60 ft and 1/4 times were consistently 2 tenths of a second HIGHER than the vbox 111.
so in the settings i have now my times are tecnically higher than they would of been at a drag strip by 2 tenths average.

lol at a blind man playing darts. it aint far off jay the same as my arse dyno aint

as for track my car would be a weapon as the pace is unreal and you have traction to go with it. but you have the weight saving on your side il give ya that mate. its all about out and out straight line speed and grip for me though mate, il never have enough hp lol

http://www.performancebox.co.uk/down...CHvPB_Test.pdf

well according to this test report the gtech was within 0.05 seconds of a racelogic v box using 12" rollout, so im gonna change back to 12" and do some more runs as the ones ive done are higher times than they should be.

scoooby slayer

iTrader: (4)

in reply to this again reference here :

http://www.performancebox.co.uk/down...CHvPB_Test.pdf

the gtech was closer to 1/4 time than the performance meter by alot when using 12" rollout, so in that situation gtech gave a more accurate result.

if anything the performance box makes you look quicker the gtech makes you slower than you actually are. look at the comparisons at the bottom gtech is all + numbers, performance box is -.

You may find if it really hooks up, it doesnt make as much boost in the first couple of gears and as a result you stop seeing the increased gains.

But an 11 is looking very likely, just not one that low probably.

Wont know till you actually get to the pod and try though

scoooby slayer

iTrader: (4)

ive been to hard on myself aswell chipster trying to make it accurate in the set up and its going to of added time, ive altered it now ready for another go. that 12.4 should be a 12.2 with 12" rollout. same with 60ft should be 2.2.
its early days im still learning its nice to of read an unbiased review, i was advised by red r racing to run 12" but i thought i was inflating the figures by doing so, but i was wrong it seems.

either way i love the car its immense its nice to have some figures and know there accurate within a tenth or 2

blacky.

in the mk3 wenny & me have done a 1.6 60ft think we both got 1.6 60ft in the nail to
my best 0-60 is 3.4 in the nail wenny has a 2.8 i think

still your times are good as there not small light cars gtr's

scoooby slayer

iTrader: (4)

im happy so far, 60mph above is as good as its gonna get without more boost but theres lots more to come in the launch area with practice.

im gonna use the stage lights and rollout now with reaction aswell to start practicing for the pod

if tyres arent upto the job im gonna have to get some better ones.

blacky.

Ye grip is the issue with getting off the line
the mk3 spins all the wheels most of 1st gear that's on soft compound 888's

scoooby slayer

iTrader: (4)

im gonna go see prices of 888s right now there 255/35/18 so im probably gonna

my falkens are new but shit compound i assume ? just looked the falken fk452, 255/35/18 y.

Chip

iTrader: (3)

888s at the moment are mega money, bought some just over a year ago for my clio, and the same tyres now are 50% dearer!

scoooby slayer

iTrader: (4)

i cant find a price yet but the t1rs are £170 each so i guess 888 are £250 + each

scoooby slayer

iTrader: (4)

this is with 12" rollout.

crazycage

thats better mate ,but how come you managed a 128 terminal on one run ?

scoooby slayer

iTrader: (4)

i dont know mate. its seems off to me that when you have rollout time your gaining 12" which was about 4 mph at clock start time on that last run and 0.4 of a second gained in the rollout area. but i should be able to do this at pod by just rolloing forward enough to bring the lights on shallow staging.
