I’d like to get some advice on a issue I have with my FK8 Type R. Tuners welcome.
My concern is about boost and possibly exhaust. I’m running the car with an Eventuri air intake and an HKS L-Spec exhaust. I haven’t been able to find any tuners that I trust to investigate the issue. I hope someday I can find someone to ride along or drive the car with so they can feel what I’m experiencing.
I will try to describe the somewhat negative experience the best I can in this post. My car feels like a balloon when I’m driving on the highway. !st gear no problem, 2nd gear no problem. In 3rd gear, ( on the gas ) you can really hear the Eventuri sucking in air. The sound is beautiful up until a point. The pressure is building up, and so far it’s not an issue till I get to 4th, where most of the pull is. I get nervous at this point, because the boost, intake, is really going up.
At this point, it feels like the exhaust is about to make a big BANG! I usually come off the gas to reduce this. Shift to 5th, and the boost comes on again. At times, I can drive beyond the intake sound and I just hear engine. I’m not really going that fast, maybe 130km. Shift up to 6th gear, and the boost comes on again. I ease off when I hear too much intake sound.
I often wonder if the HKS L-Spec exhaust is not suited for the FK8. Is the exhaust not flowing smoothly out the car? Does the Eventuri, create a tornado going into my engine? Going from 3 pipe exhaust to 2 pipe is a bad thing? This week, I will visit a couple shops and see if I can get an experienced tech to ride along. I should be going faster. I think the car was faster when it was all stock, TBH. It was more effortless.
I welcome any thoughts or ideas.
