So I raced a bmw 335 the other day (at the track) and he took me by about half a car I think he had a jb4 stage 3 tune injectors bov and exhaust
Any one else raced one of those cause he really suprised me
A tuned 135i twin turbo took me by a few cars and I slowly reeled him in at like 130. He's tuned, intake, exhaust, bov. Those N54 motors really move. Plus he was light as crap weighing about 135 and I'm 200 and had a 250lb friend in the car lol. I'm stock.
Yeah the 335i's are a bit heavier because it's a sedan so I would think anyone with a 5.0 could reel one in pretty easily. Nasty cars nonetheless and in not a fan of euro's. Tunes alone to those motors are good for 40-60 rwhp.
They are unreliable lol, people tune those turbos but its not made for the psi they tune too so they tend to break down a lot. My cousin has a 335i sedan and he has always had some kind of problems with it, and its stock also. But stock to stock a 5.0 should murder a 335i. Even if the 335i has a tune you should still be good.
The 1 series N54s have a significant weight advantage over a 5.0. They are 3200 pounds loaded for bear. The lowest you'll get a 5.0 with no options is about 3500 pounds.
The 3 series ones are more in line with 5.0 weights. Stock for stock, it's no contest in any race over a distance, 1 or 3 but, like any force inducted car, they can be made to scoot pretty easily. They are very strong out of the hole if equipped with an automatic, definitely enough to catch you napping if you aren't careful.
The factory "updates" on N54 engines actually detuned them slightly, which pissed off my friend that owns one and pushed him to go Dinan Stage 2.
I have off-road h pipes and a tune and we are neck and neck. Only when I shift (manual) does my friend gain any lead. So tbh, from a roll, you might need a little more to successfully beat him more times than lose. But then again Idunnno cause every car is different.
