Sävar Turbo Site

Om jag minns rätt alla gtx t4 avgashus är splittad.

Har Garret GTX4202R och 1.15 A/R i vitfyra. Spolar ungefärt 5500 rpm och max boost ungefär 6300 rpm.

Sounds like a bent rod and rod bearing failure to me. Rod bearing almost completely vanished and piston is hitting valves or head.

Det blir helt feil å snakke om kompresjon uten å ta hensyn til kamtider/dynamisk kompresjon. Har du vasse kammer på en turbomotor blir den veldig slapp med lav kompresjon uten ladetrykk. På en motor med Vanos blir det helt annerledes. BMW varierer innsugskammen 40 grader, dvs at dynamisk kompresjon...

Thanks Jens. I am running 4 cyl Volvo white block engine with 10.5:1 statistic compression (on E85) and tend to think things in this respect in this way (don´t know who´s idea this is, but sounds smart).. :lol: : - Compression doesn't change flame front speed. - Octane doesn't change flame front spe...

Shouldn´t you also consider the dynamic compression that is more crucial than just statistic compression when determining what fuel or ignition advance the engine uses and wants?

I wouldn't pay attention to the head gasket or O-ringing first, but more to the sleeves and how they are installed. The sleeves should protrude the deck app. 0,1mm in order to create a sufficient clamping force against the sleeves. Aluminium tend to have different expanding charasteristics than cast...

Vipec's trigger setting can be quite triggy. Settings in my V40 with V88 are the following: Trigger 2 Type: Optical / Hall Trigger 2 Filtering: Level 1 (Low) Trigger 2 Pullup: On Trigger 2 Edge: Falling Sync Mode: Cam Level I'd like to remain you that Sync Mode is subject to the trigger choice. I ha...

Sute, SME tillverkar dom. Poikkimäki kör dom på rallycross moterer.

Ahaa, trodde att Pasi tillverkar dom...

Andre,

You wrote down my philosophy on that Navalinea gasket working principle..

The softer material is actually three layer composition but "softer" than the steel rings for sure.

Hi ulf, Did you encounter the leakage from the head side ("above the gasket") or the cylinder side ("beneath the gasket"). What do you think, would VHT copper cement gasket help on this? I have this kind of head gasket, with separate steel o-rings that have "nails" on h...

I asked from Darton their opinion should the sleeves be decked or left protruded over the deck. This is how they answered: "Hello, We recommend decking the block flat with the sleeves. The reason the sleeves are originally left up from the deck is to make sure they are completely seated. If you...

Med samma turbo i en 2,3l Saab blev det 660 hk.
