another update !!

after a lot of messing around i beat my p.b of 12.8 on sunday (6th april)

it now does 12.5@118mph

i now own one of the fastest mk2 astras in the uk form what we know of and 100% sure the fastest 8vturbo mk2 astra in the uk

to say im happy is an understatment !!

but im not stopping at 12.5 i want it very very low 12`s or oeven very high 11`s

i can up the boost a bit more ( atlest another 10psi ) and im only running just under a 50 shot of gas so theres more to come from her but how much more befor it goes bang i dont no but we are going to give it a try


a big thank you to james,and jerry @diyautotune ( the cars covered in diyautotune graphics) and everybody else that helped me out over the last 2 years

tdc of vauxhall is tooth 21


on the m/s unit the settings are something like this

out put 1 = trigger tooth 11
return tooth 20

output 2 = trigger tooth =41
return tooth =50

ive used this for the last 3 yars

another small update

after august last year ( i blew the engine to bits after dropping 2 valves )

i built another engine over winter and this time i have left the nos off of it with a few changes to the inlet and turbo manfold and the turbo and its first outing it did a 12.3 standing quater :) well happy with that

a few week later we decided to take it back and give it another go and this time a 11.7 @117 with a blowing turbo to manifold gasket and thats only at 22 psi :) i couldnt up the boost as i was running 95+ duty on the injectors ... till now ive got a nice set of 1000cc injectors sitting here ready to go in ...

not only is it the fastest mk2 astra in the uk its also the 1st mk2 astra in the uk in the 11`s and its all motor the direct ports half put in but i refuse to use it at the mo

and for some of you that used to no the car ( the diy auto tune car !! ) its had a change for this year :)

heres a pic of it now :)

now 10`s for the old girl !! but i might have to use the nos to do it but the turbos rated to 650bhp and 35 psi of boost so we will see what happens with that 1st and ive got water injection to fit aswell

big thanks to james !! over the years ive picked his brains a lot

all i can say is NOT BAD FOR A 8V
