Hi,
Small update; engine rebuild
.
New pistons, conrods, clutch, big valve head ...
Already driven +1000 miles and amazing. OE Bosch dump valve broke straight away
, which has been okay with OE head / unported exhaust and intake headers.
Now Forge piston type and it is more or less like a "horse"
(i-ha-ha-ha) when ever a little boost and I lift the gas pedal it start to make noise.
First feelings, spool up some 200 rpm earlier; 1 bar (turbo GT3071R, 0.86):
2nd 4400 rpm
3rd 3800 rpm
4th 3400 rpm
With 465cc injectors and 100% duty cycle EGT goes above 950 degC already with 1.5 bar boost/+6500 rpm. With OE head I could see black smoke coming out of the exhaust with +1.7 bar boost until almost the rev limiter (7300 rpm).
When accelerating hard (like quarter mile run), changing from second to third gear Apexi has recorded 7800 - 7950 rpm readings eventhough the limiter is in 7300 rpm. Limiter is obviousely too slow
.
Also one notification, earlier for example with second gear, when the grip was lost the boost was coming down straight away. Now I can see 1.46 bar boost readings in Apexi with second gear with spinning wheels...
I will go to RR quite soon, as soon as the tuner get it work again, some software problem. It is the very same, where I have always got my car tested. The results are comparable against each other.
