So the car is a 306 sedan from 96. xud7 engine with 9mm bosch, turned lda pin, k14 at 0.9-1bar, xud9 gearbox, straight through exhaust. Made a hood scoop but it looks like is inefficient. When cold it reaches around 1 bar of boost. After it get's warm and start to get rough with it the boost crashes to around 0.4-0.5 bars. The turbo runs defiltered so warm air from the engine.
Is there any change except fmic to reduce heat soak?
The next thing i has thinking was if i can fit a small air filter (motorcycle or for horizantal carburators) direct to the turbo. Are those filter permisive enough? What size is the inlet on a k14?
This isnt right, your boost shouldnt halve when its hot, those kind of boost pressures from a K14 shouldnt really cause severe heatsoak anyway. Does it black smoke on boost when it does this?
No bonnet lining. It's a xud7te from a 205 d-turbo. Mounted the intercooler myself. Not too much extra fuel so can't really figure out the lack of boost after getting warm.
