update

fitted fuel pump today 255lph

everything worked spot on after first start up

so... as i was on the rolling road today i changed the oil and filter, and 50/50 antifreeze and water

then upon the first time driving it since new rad actuator and heat rap i had a quick blip down the road full boost 3rd 4th 5th then cam back and pulled in the drive, smoke everywhere!!!

inspection revealed manifold and downpipe glowing bright red through the heatwrap!!! not good, drove to the rolling road water temp 95 as the turbo was that hot due to heatwrap it was boiling the water and oil temp was also 20 degrees higher than normall at 100 instead of 80 all this through normal driving so off came the manifold wrap straight away, and everythings sorted water 85 and oil 80

word of advise dont heatwrap your manifold!!!

then came the dyno!

spec as it stands

low milage c20let block
86.5mm courtenay low comp pistons
steel rods with bronze grudgen pins
arp rob bolts
1.9mm cometic head gasket
coscast cylinder head
courtenay sport cams
2.0 8v sump baffle plate
astra vxr injectors
adjustable fuel pressure regulator
modified throttle bodie
enlarged tophat
front mounted intercooler
200sx tubular manifold with vauxhall/t3 flanges
garrett t34 .63 escort cosworth turbo
forge actuator
dawes device manual boost controller
pvd big induction kit
3" downpipe
full 3" exhaust system
scorpion 4" outwardly rolled backbox
f28 gearbox
evo5 chips
1.2 bar of boost

ttok it in for a setup tonight it made 290bhp on test run and air fuel ratio was 15's!!!! how the hell it was still alive i dont no!

after 4 hours of messing heres the results

1.2 bar of held boost on the mbc
air fuel 13.8/9 full boost (need to get this down abit)

357bhp @6073rpm
320lbft torque

very please with that just a few issues now

1. lamba must be funcked as its rich as hell 9's on idle
2. running abit rich at full rpm/boost
3. cannot seem to get above 1.2 bar evan with actuator pipe off (actuator strength?)
4. maybe a dodgy fuel pressure regulator as altering anywhere between 4-5bar does not alter the afr much top end?

still happy though and ready for donnington this weekend!

astra16V2004 · 03-04-2008, 21:47

nice figure mate!!!! bet your well happy.did it cost much to have it checked and set up??? will be worth every penny though

jamie gsi16v · 03-04-2008, 21:48

£80 mate went from 290 to 357 so 67bhp for 80 sheets im happy!!

Adam · 03-04-2008, 21:58

sweeet

jamie gsi16v · 08-04-2008, 15:23

now found out why it was running abit lean top end, the voltage at the fuel pump was getting only 11v same at the battery but at the alternator i was getting 14.6/7v so the pump had no power at the top end. stuck a load of new earths on it today and im going to test the voltage later

couple of updates,

friday i was up very late getting the car ready for donnington, fitted two new proxes t1rs and blead all the brakes with motorsport dot 5.1 from as performance along with fitting my ds2500 race pads

wip

new pads

then came tracktime at ists donnington park show, first session was good but abit slippy still did amazingly well, managed to keep my brakes not like last time,

second session was bone dry, gave the car everything it had got and did amazingly well until the last lap smoke poured under the dash we came off thinking nothing of it when the car burst into flames!!! talk about panic!! marshells put it straight out with fire extinguishers we left it too cool towed it off the track entrance and checked it over, turned out the breather pipe from the rocker cover to the dipstick tube had got that hot from heat off the manifold it caught fire and burnt through spilling oil onto the manifold and setting the bay on fire including my carbon bonnet!

we wiped everything down as best we could but what a mess, went to just novas and corsas stand and bought a rocker cover breather in silicone and fitted it, couple of turns from the key and it fired straight up.

then session 1 on sunday we went out all was well apart from lack of fuel on corners (swirl pot needed)
session 2 saw disaster again absolutely destroying the passenger side outer cv joint, car got towed off the track and we took it too the carpark again where we stripped it, went home (30 mile trek) got another shaft, came back and fitted it then did another 3 sessions totaling 7 session over the weekend. but had a really good time, vids to follow.

pic of bay after fire!!

after a cleaning session yesterday....

jobs to do now after first track day

swirl pot
custom manifold heat sheild
louvered bonnet instead of carbon bonnet

CortraGTE · 08-04-2008, 15:34

Oh ****! Well it didn't turn out too bad then but fuuuuuuuuck! Bet you shat it!!

Sweet car mate!

jamie gsi16v · 09-04-2008, 16:52

couple of pics i just found from another site of my car at donny

leesturbo · 10-04-2008, 19:20

the white morrettes look good
against the white wheels

hmmm the fuel issue on corners
seems to only effect the in tank
setups i have external and have no
issues!

LongLiveTheNova · 10-04-2008, 20:17

Looks sweet on track

jamie gsi16v · 12-04-2008, 18:15

todays update

fitted an electronic power assisted steering pump off a 106 gti

one pump

one loom.... consisting of permenant live, switched live, and an 2 earths

few hydraulic pipes and wiring and welding/fabricating later it was in, mounted neatly behind the passenger side headlight

and i must say its the best mod i have ever done to any of my cars, i had a power steering rack fitted and no pump and hell it was hard to steer especially with all the weight over the front wheels, now i can lock it over with 1 finger!!

Jamie_F · 12-04-2008, 18:55

would the boost not rise no matter how much you adjusted the controller?

ive seen this a few times with the cheap ebay coolers, they can cause a massive pressure drop at anything over the 1.2 bar area, one guy fitted a boost gauge before and after the the ic, before the ic was 1.7 bar, after 1.2, so the turbo was working it nuts off for no extra gain.

jamie gsi16v · 12-04-2008, 19:29

im not sure tbh mate, carnt see as it will affect it much? i ran the same boost pressure on my kkk with the fmic as the calibra ran with the standard cooler, it will spike to 1.5 but only hold 1.2, the mbc just doesnt seem to do anything? we did take the pipe off the actuator to see if it would produce silly boost but still it would only push 1.2 bar, im unsure what the problem is as id like to take it to upto 1.4 bar really? any ideas, im sure its not the fmic as it has brilliant flow.

leesturbo · 12-04-2008, 20:36

funked actuator? not read the whole thread if youv'e
already addressed that, if not huge boost leak,
dump valve opening on higher boost?

jamie gsi16v · 12-04-2008, 21:55

was going to ask you lee what actuator/setup you are using to achieve 1.4 bar, i have an uprated forge actuator on at the moment and id of thort that would be more than enough, no boost leaks to my knowledge but i will check, and im using a baileys dump valve weather or not thats opening i dont no, is there a way of checking?

cheers for any help in advance,
