What is flutter dump? the otherday a r33 blew past me and did this i wana know how to do this

Are you referring to the blow off valve noise or "turbo dose" noise?

If so here's a thread all about it.

i didnt think it was even possible to get wastegate flutter. I think you may be meaning an external wastegate? if the car was really loud going past while on boost, it would be that. its a screamer pipe that goes onto the wastegate. this is illegal to have, but on the right setup it sounds good.

Flutterdump is when the BOV is a cheap POS or the spring in the BOV is too stiff and U back off and it starts fluttering then the BOV vents. It's considered a problem and can be fixed with a much softer spring. As long as the BOV is plumbed back like it should be, it can be soft enough to stay open on idle without and probs. As soon as U give it the tinyest bit of throttle, it slams shut.

      Nissan needs to forget about building SUVs in every size possible and bring back the damn Silvia/200sx duo to compete with the 86/brz. Maybe with the Honda type r motor pointing the right way

      Good to see you followed your heart, got your dream car and have it pretty well sorted out now. I think anyone can get caught out with a seller not being 100% honest about a cars problems. Can relate to all the electrical issues, had similar issues with my first car (mk2 escort) ages ago

      Honda's hybrid system can be easily scaled up to PHEVs. Series hybrid at low speeds, at higher speeds the engine directly drives the wheels but there can still be some power bled off to charge the battery + the electric motor can still provide parallel assistance too. It's really only a question of will at that point. Toyota's PHEVs are selling incredibly well at the moment because of the flexibility. You can run on EV mode when it makes sense, but if you're planning on doing a long highway drive you can still fire up the gas engine and not have to worry about dealing with the rather miserable state of public charging infrastructure.

      Only reason to keep a MAF on your RB25 is to be able to easily calculate true VE if you know what the factory voltage curve represents in grams per second of flow. Also allows you to do things like pull the original OEM ignition + AFR target tables and use those as a starting point for your base map. Once you're well and truly done tuning though there's no need to retain the MAF.
