time for a update

done another day on it today and things are starting to come together now.

brakes are on and ready for bleeding (after i get a few fittings from think auto)

was quite a job to get the calipers to clear but they do now there is prob 1mm of clearance between the caliper and the wheel, that should be enough.

thats one job finished there on and not coming off lol

im getting to the point where the jobs ive been putting off as thats not needed jobs are starting to be the only ones left or even holding me up

so i decided to mount the coil pack, im using a coil pack from a C14xe iirc as it has built in ignition amp, however with mine being a non coilpack head i needed to make a braket to hold it after a few hours of messing i finally came up with this, im happy with it now, leads fit perfect and there is no movement in the coil.

just needs to come off to be painted.

also fitted the turbo, manifold exhaust downpipe today filter and pipework few pics.

those not familar with the mk2 will not know about the 4 inch hole in the inner wing, the filter sits dirrectly above this hole so im going to use the foglight duct to put air upto the filter.

also thought i would fit my irmscher rear lights

they suit the car well with all the black bits going onto it

and for a few outside shots as it was looking good

there is something about the car with this green bonnet fitted, for some reason it just screams track car at me, i put the white bonnet on it and it just dont have the same feel lol.

is it wrong i think it looks kool lol

Looks awesome mate, I quite like the odd coloured bonnet too!

Were you down in Plymouth the other day? Could've sworn I saw you travelling the opposite way on the A38 in the Mk3 convertible...?

I can't wait to see this finished... love you.

top hose dont even go there because my top hose goes into the bottom it needs to go past my 4 inch inlet tube

fans i found some 7 inch bike ones in the skip at work today, did not know if they were any good or if they were even 12 volt so i hooked them upto a battery, thought ill leave them and check them in a bit, althou i forgot about them and did not go back for 3 hours

were still running thou so they will do

baring any problems a gen over 400 bhp

leesturbo · 26-04-2008, 23:30

1.4 bar will be 400+ on that without a doubt

LongLiveTheNova · 26-04-2008, 23:59

Bay looks cool as f**k

Trig · 27-04-2008, 09:05

Any closer to mapping it yet

wazpaz · 27-04-2008, 12:39

nice to see you have sorted the airfilter too!

sbd16vastra · 19-07-2008, 11:11

well after chatting to a few ppl at billing i realised i was well out of date with my thread LOL

as most of you should know its now running, im stil having teething problems one of which is a head problem that is going to need a new head.

few pics from billing this is after she was cleaned LOL

anyway now the car is mostly in one piece i can start doing those little touches, the outside looks cleanish now so decided to start on the inside and here is the first

because i dont have any door cars the doors have always looked quite untidy

quick rub down and a few coats of satan black hamerite

the finish is more like the passengers side the drivers looks so shiny as its still wet

yeh i have been a little lapse lol, aint done alot so tbh dont bother with updates.

been a while since a update so here is one.

most of the work on the car atm has been making things stonger or better, when you build these cars it is always the case that some things get rushed first time around.

one of these things was my trigger wheel for the engine, on my engine i run an external trigger wheel, when i first went for mapping crank sensor errors stop'd the mapping and this was put down to a poor disc.

the dimensions of the original one was a tooth that was 4x4x4mm but the autronic is more happy with a 8x8x8mm tooth.

this was the original

at the start of august my training moved onto machine shop work PERFECT, so after a few weeks of learning lathe work it was time to start building my own stuff

first of was the trigger disc.

started with a lump of metal

and after some measuring and maching it begain to take shape.

the old trigger disc was totally flat that ment that the only thing that centralised it was the 2 bolts holding it on this was not good enough so this time i make a recess to hold the pully onto the disc.

i then drilled all 6 holes to hold it onto the crank bottom pully, on the vauxhall engine all the bolt hole spacing is different so the disc can now only ever go one one way.

next the teeth were milled using a dividing head to make sure the teeth were perfectly 180 degs opposed.

im afraid ive lost the pics of this

.

but by then i was getting the hang of this machine work.

good job really as 2 days later i lost the ablity to release the cluth, because im running a twin plate cluch the release bearing needs to travel more than a standard clutch now when i was fitting the engine i had to make a temp fix my fixing 2 release bearings together.

this ended in tears LOL

upon taking the box off this is what i found

so back onto the lathe a new bearing was purchased.

again this needed to be extended but this time i had new skills.

so fired up the old lathe again and made a spacer to space the bearing..

this bearing set up works perfect im very happy with the feel of the clutch now

.

well with most of the mechanical work done it was time to get the car ready for its first track day. one of the most important thing for me was to get the F/G bonnet on, due to it being a manta 400 rep one it has massive cut outs above the turbo which will help alot with keeping everything cool.

i also spent a few days tightening things up which has made a massive difference to the feeling from inside the car it now feels alot more solid less vibration and rattles.

onto the first track day combe eurofest.

suspension was setup with a tape measure as he ran out of time (was still bolting the gearbox on 3 days before and only got the tyres on that morning etc)
the engine was running a whopping .7bar of boost, and was in limp home mode due to a faulty MAP sensor.

chip det checked it with in-the-ear headphones hidden under my crash helmet ON the track.

however the day was a massive sucess, the car performed better in both handling and straight line speed than i expected it would, the handling is more like i expected it to be once set-up so for it to perform with the most basic of set-ups, was a real treat.

some pics of it on track

little wheel cocking going on

overall very impressed with the car, best lap of the day was a 1m24 not bad for a first day at combe.

couple of videos of the day

After a fantastic time at the weekend (eurofest at combe) i really wanted to know what power the car was putting down.

i was not to intersted in the actual number just what the number was for how it felt, just to give me a indication of what to expect when i get to the power figure i would like of 400.

i booked the car in for a power run session at jkm in portsmouth a very good set-up and the guys operating the rr know what there talking about and what there doing, very impressed with the set-up and the way they run it and id highly recomend them to anyone.

the car was run in 2 different boost settings the first was what i really wanted to know what it was at the weekend so the first run was done with .7 bar spring pressure as i have been driving it around.

this made 273bhp and 280ftlb of TQ these are both at the flywheel.

this was a little lower than i expected purly due to how the car drives, althou im not disapointed as the car goes very very well for what is such a low power reading.

we then made a very pikey boost controller (bleed type with a hole in a piece of brake pipe) this enabled us to achive 1.2 bar and another run was done at this boost level.

this made 309bhp and 330ftlb of TQ again at the fly. (261.3bhp and 280ftlb TQ @ the wheels)

some graphs of the day

BHP vs Torque

BHP vs boost

BHP vs AFR's

as you can see the car had no problems holding the boost and it makes the boost at a nice early rpm, im very happy with how soon it makes 300ftlb of tq (the final value we would like all across the range)

however due to the fact this is still a basic base map, with most of the adjustments being just making sure the car has no det, in part the timing has been removed to much this shows by how fast the TQ falls instead of there being timing in the map to bring this back up the map is far to retarded, this will however change once the engine is mapped.

it is also shown in the afr graphs how rich the engine is dropping well into the 10's above 6000 rpm.

so overall quite a bit to come from the mapping and obviously the fact it will just get more boost,

overall im very happy with the car at the moment the jigsaw is finally starting to come together.
