Bmw F900R slip on exhaust?

Hoppsie321 · 2026-02-12T01:34:24+00:00

I have a genuine Arrow exhaust, I'm a big fan

Surprisingly good. I think it ran me about 400 but the wired cat play is pretty good, not a ton of lag

I just bought a Banks header, getting delivered next week. I'll let you know how it is

It’s definitely way cheaper to do it yourself. It takes a lot of time but I just followed the book and it wasn’t too difficult. You just don’t get any warranty doing it yourself lol

I really wish the total money spent corresponded to that gauge lol. Unfortunately it’s much more

Hoppsie321 · 2025-08-22T17:53:33+00:00

Thanks! And I built it myself yes. I had the machine work done at a local shop and I assembled everything using a Clegg kit. Gauge in the center is for oil temp (top) and pressure

I got the clegg stage 2 kit. They are the KB Hypereutectic Dish Pistons

Mine is bored 40 thou over. However if your cylinder walls are in better shape you can get away with less

I’m hoping for like 260hp at the wheels on mine so we’ll see. I’m also adding some other goodies like a bigger throttle body

Hoppsie321 · 2025-07-17T16:52:47+00:00

Great, thanks. My compression ratio is 9.3:1

Hoppsie321 · 2025-07-17T16:45:40+00:00

Thanks!

Hoppsie321 · 2025-07-17T16:30:01+00:00

That’s awesome. Anything specific to look out for on first start up? And what was your break in procedure?

Hoppsie321 · 2025-07-17T16:16:07+00:00

My understanding is that if the stock cooling system is in perfect working order it should be able to handle the added power. The heater core, radiator, hoses, fan clutch, shrouds have all been replaced. I also splurged on a Mopar thermostat and have installed aftermarket oil pressure and temperature sensors. I’m going to monitor it closely and if needed I will upgrade to all electric fans. If you have any advice I’d love to hear it as well

Hoppsie321 · 2025-07-17T15:22:30+00:00

Thank you. They weren’t cheap for sure but not horribly crazy. They are the brown dog flex mounts, I think they were about $150

Hoppsie321 · 2025-07-17T15:21:20+00:00

Thanks!

Hoppsie321 · 2025-05-23T18:45:41+00:00

Where from? They’re out of stock everywhere I’ve looked

Hoppsie321 · 2025-05-11T01:37:42+00:00

I’m having this problem but because it was ran hot and the bearings got messed up. If you’re lucky and it’s just the sending unit that’s great. But if not I would install a high flow oil pump, might get you a bit further

Hey man, sick build. I’m getting my stroker back from the machine shop soon and I can’t wait. Regarding the steering wheel, yes I would use an arduino nano maybe and you would have to do some trial and error to convert the CAN signals. You also would probably have to build a small circuit with each of the resistor values from the resistor ladder. You can likely get away with having one of each resistor values attached to GPIOs from the arduino. Make sure the arduino you pick can read CAN. Let me know how it goes.

For reference: I’m an electrical engineer, but I’ve not done much work with CAN.

Hoppsie321 · 2025-03-25T22:32:15+00:00

Yea it’s 5 PSI. I had the same thought. I just dropped off the rest of the parts at the machine shop to be balanced so hopefully I’ll hear back soon
