Rob got a 12.1 @ 124 (now officially the fastest astra in the UK) despite the fact he was still on trackday settings as he was interested to see what the car does in EXACTLY the trim it is on track rather than when its drag prepped, bet he is gutted now though as thats so close to 11s that he might have had a real chance if he had reset the geometry and swapped to 15s!

I got a 12.9 on my nova, @103 mph, I only went flat out in first and second though, then just cruised through the other gears as I had a lean spot, until that spot I was ahead of Rob though, my 330ft was 5.37 and IIRC his was 5.5something.

I richened it up a bit for the next run, and it pulled lovely through the first 3 gears but then when I went into 4th I discovered the cause of the leaness, the jenvey fuel rail couldnt handle the boost even (after I had re-enforced it during fitting) and it relieved clamping pressure on the O ring seal in injector number one and was allowing it to leak, couldnt run again after that, as I will need to fix that problem first.
Found out in a quite dramatic way, the fuel caught fire, lol, luckily no major damage though, just a bit of loom to remake.

Will be interesting to see what mine can do when it gets a proper run.

Good times you mapped the astra didnt you chip

Yes mate, the engine was specced out by me and rob initially and I mainly built it while Rob helped on some bits first of all, since then the spec has evolved a little and rob has rebuilt it fully himself this time, and I have mapped it for him as he cant afford to pay someone who knows what they are doing so he has to settle for me

dojj

iTrader: (3)

that's good news mate

will you be writing it up for a mag then or was this purely in the intrests of arsing about

this is the bit i can't understand mate, are you saying that the boost was backing up the inlet of the head and pushing out injector number one?

i've sen this happen before, but only in the case of mine and squeaks sierra's where the little 3mm plate used to hold the extra 2 injectors in situ that were stuck into the plemun isn't quite man enough to handle a bar of boost, but not heard of this happening to injectors fitted to the head

is it a simple re-engineering fix or back to the drawing board?

my mates astra mk4 ran a 12.8 made 437bhp on the dyno

Well you cant be that bad chip

crazycage

thats a geat time!!! you wouldnt happen to have the rest of the times off the slip??
p.s the 12.1

Chip

iTrader: (3)

I dont remember the whole strip, Rob should be able to post.

Think it was
60ft 2.2
330ft 5.5
1/8th 8.3
1/8th mph 96

If its not that, it was certainly along those lines, lol

Chip

Well, all the "baldy mapped" (as rob puts it, lol) cars seem to be doing pretty well so far, not had any complaints, so yeah I guess thats true to a certain extent, I was only making a tongue in cheek comment as some people look down on "home" mappers thats all mate.

Great result for you and Rob Chip. Well done. Rob's Astra I hope to race at Combe soon! Hope you get a chance to get the Nova fully sorted so you cameol

crazycage

nothing wrong with home builds and mapping ! infact its more rewarding.

Si B

iTrader: (59)

last word should of been can! So you can make full use of it's potential! Are you both on track at RSOC Combe?

zvhrst

quickest astra 12.1.......

i ran my mates astra in the vid posted by danneth and did a 12,8, first time out in his car, with 17's on prada's, no diff, and 35 psi as we drove it there, also full road trim and sparewheel still in boot,

so you think strip it out? some 888's with big walls on 16's with less psi and it may do a 12?????

He never said it had, nor did he say it will. Nice one, Chip, how far off the fastest FWD vauxhall is he?

Benni.

Rick

Nice one Chip, it's on a 3071 isn't it?

sbd16v

60ft- 2.2042
330ft- 5.6278
1/8 8.15
1/8 97.4
1000'- 10.23
1/4 -12.10
1/4-124.11


impressive time with the spec, but as is much theroy the only proof is in the pudding should really be in the 11's with enough weight lose and good drive thou, there just seams to be alot that should that never do

i have had a problem with my exhaust manifold so if its fixed in time yes if its not no

alothou me and chip should be there in the clio i belive if the astra aint working

sbd16v

yeh the smaller gt3071

sbd16v

on a drag strip very far off specky has run 11.3 in his tigra, 11.5 in its new spec

zvhrst

i wasnt sayin the mk4 gsi of my mates would do a 12, it was more a questiion,

the car still isnt finished tbh,
it made 437 bhp at 1.5 bar, on a GT3076 turbo, with forged bottom end, standard head and cams, and std inlet, DTA p8 pro, and siemens injectors
nortech echaust manifold and downpipe,
and runing a bit rich at 10.8 : 1 to be safe, map 2 will be for draggin when rest of spec is done

mods still to come are nortech inlet manifold, more boost (2.2 bar) and an LSD,

am quite sure there will be some big things happening with his car i just hope he keeps letting me drive it lol

Rob

whos record did you break to be the fastest uk astra ? neil adams? bluesprint one ?

Chip - You back at work this week, need to have a catch up.

danneth

what are you on about and rolling the eyes? think you need to re-read it mate

sbd16v

i find it very hard to belive that power figure from standard head, cams and inlet at that boost

what RR was that on ???

you said above it done a 12.8 ??

zvhrst

yes mate 12.8 @ 118 mph

black mk4 GSI, and head n cams n inlet are std, (i built it)

http://www.youtube.com/watch?v=oGWDlBs1mpA&NR=1





live mapped on the road,

sbd16v

well i belive blesprint was untill this weekend 2 weeks ago the fastest with a 12.4 , then a lad with a big build 8v run a 12.3, the lad that now owns russ's old mk2 ran 12.3 on saturday, then i ran 12.1 today

and yes there are several with big specs, i will not be at the top for close to as long as i was in the first place then bluesprint was for the past 2 years.

sbd16v

that is the most power i have EVER seen from a let on standard head, cams and inlet seriously good going

zvhrst

its got all the right bits in the bottom end too tho,
and fully lightend and balanced, was even balanced with the clutch on and the aux pully to get it perfect,

and it is a z let, not a c let,
i know you probably know lol, but somone reading thread might not realise,

i love his car lol, yesterday when i ran the 12.8, first thing i said to him was,
"do ya a straight swap for my focus Rs and 3 door" lol

leecavturbo

good effort rob. i missed your call.
lots more in this car with little areas sorted

sbd16v

dropped the 0-100 to 8.3 now
