Ok, just be careful, because I’ve heard of factory LCA’s bending on occasion.

Oh sorry I misread your previous message. Believe the guy uses the knuckles to strap down. I will absolutely NOT let him use my new factory LCAs because they WILL bend. The old ones bent from endlinks being the wrong length lol. Fuck that.

Will let you know this weekend when mine goes on the dyno by my guy said he was doing that method already.

The majority of operators I've seen typically just strap around the LCA's. Not saying that's good or bad, just saying that's been the norm that I've seen.

Where are you guys strapping the car to on the dyno? I need to schedule a remote tune soon and the shop I'm planning on using doesn't typically work on E46s. I've got some beefy SPL Parts rear lower control arms, but ideally I'd have it secured elsewhere.

The dyno operator at the one I went to used t hooks. Take off the rear jack pads, put the t hooks in and strap it down.

This is how BMW straps the cars down for shipping too.

No Dyno Curves posted for any 296/288 cams it seems. Has anyone built NA race motors and published their Dyno sheets?

I feel like most folks building race motors (and it's probably a very, very small number) aren't concerned w/posting graphs on forums or FB...or social media in general. The only person that I know for sure that is running big boy cams is Mike Cotter, but his cams are custom, and he's running a stroker motor as well. Unfortunately, I've never seen one of his more recent dyno's, but rumor has it that he's making around 400WHP now.

Three fifty for full track car on 91 and no cams is pretty good.

[CrisSilberGrau]

Ethanol, track specific timing targets... supporting mods. Still very high number for that car. Well done imo.

Has anyone seen what HassanEido posted today on Instagram? This must be a Wednesday car for sure aka factory freak!

Guessing 340ish.

340ish with Karb intake? Boooooo 😭

[jet_dogg]

I’ll try to get a baseline for my track car. Currently it has CPI headers, BW race exhaust, and SPAL fan only. We’ll see what it puts down after it gets a Karb intake, IAT relocation, and HTE tune. 350-360 WHP would be cool.

Guessing 340ish.

^^^Sounds about right, and yep, the factory headers are def holding the engine back now a bit. Looking forward to updates, and thanx for contributing/posting!
