Alex at ABR built me his 3.1 liter "Punisher " engine with forged rods and pistons, ported head with full Ferrea valvetrain. The engine is not louder than a factory N54. My Indy has the same car as I do and we've idled his factory engine next to mine. I've never had any false knock or any codes related to knock.

The choice of piston material and the piston to wall clearance is crucial to keeping noise down.

Alex did everything right and tight.

Good to see some feedback. Where are you at power and tuning wise?

You can fit enough tire on the 335i. Guys are running 160mph+ in the 1/8 on 275 drag radials However people in the 335i community think running r888 on ots coilovers are a great way to to cut a 60ft.

guilty...

2.13 60' on kw coilovers and an 18" street tire

trapped 127 though lmao

I ran a r888 (19" 265) and managed a 11.79@119 on stock turbos. Great tyres but it definitely would be great to get a bigger tyre on the car. Especially for road use. Can't run drag radicals on the road here in the UK. Something like a 345 would be awesome. Now on GC turbos with port meth injection. The torque comes in so fast that even an r888 struggles in the first few gears.

Car is still on stock M sport suspension. Was still just a 1.937 60ft.

instead of throwing more power, IMO a lot of these the high hp builds I see on these forums could really benefit from some chassis mods. at least replace the subframe and diff bushings.
