Reaper engine you say? Had a theory when you said you bought "pistons, rods, cams, valves, engine studs". Just gonna put this here... https://4pistonracing.com/products/k24-k440-2-5l-complete-engine-drag-race-super99-2021-spec And from a computer science background, shame upon thee for having...

My ARK has a whistle near peak RPM, just a thing a lot of times. I had a shop go over it and check for leaks when they were welding in a new resonator to it, said no leaks. Just a quirk of some exhaust tip/muffler setups basically.

True, woulda figured that one out in practice, forgot the theory! Thanks. I read fuel pump fuse doesn't work, car won't turn on without it. But unplugging the in-tank pump, now that might be a idea, will be giving this a shot in the next week or so, appreciate it.

Of course I could just pull the injectors off and have them shoot into a container of some sort sure, but is there really not a way to disabled the fueling (without some honda software)? Would like to compression test the car, managed to overrev it bc I either mishifted terribly, or got locked...

More power you got more hop you got. On hondata basemap for 93 a RMM will no longer suffice, as figured from personal experience. Will do the whiteline kit one day hoping I can return back to nearly having traction in 1st and 2nd, sometimes I lose it in 3rd too if the tires are too cold. Life...

You're definitely not wrong, just the issue is the ECU is too particular on this car, If I wanted to learn more about the bosch ecu i'd prob have to go german, and we all know that's a money sink regardless. I don't intend to get into crazy timing changes and other stuff for the car, just kind...

Yeah I've read through that section. Good to know for general tuning, but the deeper level "If you see x, it mean y" is kinda missing for my specific use case. I know my AFR is generally running higher/leaner than it should in closed loop, so over time my fuel trims trend richer. This is all...

Entirely fine with me, can buy a new engine if needed. I have 2 other cars I can drive, money to buy the engine if I want. Everyone started learning somewhere. Will likely be buying some classes on tuning this platform soon as well. I understand the risks associated, I'm really going for the...

Basemap hondata 93 octane w/improved throttle response. See I'd like to get a custom tune, but even more I'd honestly like to take the risk involved (yes even if that means turning my engine into a grenade) with learning how to do it myself. Fairly technologically inclined, but this is a new...

No prob, also not to assume what should be obvious, but none of this matters without a tune, so make sure you get a flashpro.

Most def required high flow cat/catless downpipe. At 400-450whp you'll prob destroy your stock cat. And the downpipe free's up a lot of HP itself. Otherwise seems like you got the bang for the buck plan, though the hondata fuel system is a little overkill (albeit the best complete fueling...

Hey guys, posting here for visibility. Stuff on hondata's forums just takes a while to get responses for. Does anyone here having tuning experience and can help point me in the direction of things to modify? Post on hondata is here: https://hondata.com/forum/viewtopic.php?t=25412 tl;dr L.trim...

There's precut film for the FK8, you can actually buy it yourself, just no guarantee you'll put it on right, and generally you get a paint correction alongside ceramic + ppf, I know from personal experience. Used XPEL Ultimate, solid stuff so far, been on for 2 years and its done it's job. As...

I'd say the same way that person described it in the screenshots sent, the drone is still there, however it's extremely livable. I no longer get out of my car with migraines after a 20 min drive lmao. The severity of the drone is <50% of what it was before. The ultra quiet may just push you to...

Lucky you! Ultra quiet didn't fit in mine bc the bends were weird, I got the bottle style, I'm sure the ultra quiet will kill a ton of the drone. (Can't say for sure that one won't affect the sound, but should be barely noticeable).

Some googling leads me to believe you! Fair enough, well regardless I've seen mixed results with people with sound dampening and anti vibration material in cars. Only real results I've seen are as mentioned before, get another resonator welded in that bad boy. If I were to put it into...

Vibrations are exactly what we're trying to be rid of here, drone is just resonance most of the time, which is basically just the sound and metal vibrating at the same frequency. Can't stop the sound from vibrating, but if we can stop the metal, we still hear the sound as it is naturally, add...

I've got the ARK exhaust which is a similar sound as the Invidia (they were my 2 choices since I like the deep sound). Drone between 2.7-3.5, super bad, headache inducing bc it's not really volume as much as it's the resonance. Got a vibrant 3in resonator welded in (in addition to the already...

All that considered, and a custom tune, I'd say you'd be easily looking at ~380whp+ comfortably, and likely reliably too (as reliably as a tune can be, depends on the place that tunes it). That is so long as you're using 93oct fuel. I've got the Eventuri intake and it's a great thing, it...

Exhaust leak maybe. If you've done downpipe I assume it was with hondata, and if it's a fresh exhaust install, even more chance. Most exhaust shops will do exhaust leak checks free of charge in my area, see if you've got something similar. I had one done when I installed my ark exhaust, but lo...
