335d Engine Compartment

Some pics. Wonder how this puppy will respond to tuning?

The 335d should respond very favorably to tunes. Once the restrictive exhaust is removed, I anticipate 400-450whp and oodles of torque.

Of course this is all just fact-less speculation on my part on what "feels right".

It will be a fun day when the 335d is gunning for our 1/4 mile records

I'd say 350-380whp. ESS reflash makes 335hp and 630Nm (335d). Keeping in mind that 335i with ESS reflash (stage 3) makes almost the same power as Vishnu or JB3, a well tuned 335d shouldn't exceed 370-380whp, imo. Nevertheless, performance would be impressive.

Go to the UK section - There has already been well over 2 years of development on these engines. No need to speculate.

I was looking at the times of this chipped 335d. Mid 13's at 105mph, right about the same as a stock 335i. But with great traction, (1.80 sec 60') high 12's are there. Not bad. How much faster will they go is the question.

I think the 335d will always need more peak power than the 335i to get similar times just because the torque curve peaks/plateaus at a much smaller RPM range. It only has a redline of 5000 RPM, compared to our 7000 RPM.

A tuned 335d runs 106mph in the 1/4 mile, no match for a tuned 335i.

Just wondering if the 335d used the same turbo as the 335i? Anyway, the diesel engine can withstand alot more abuse than the gasoline. So 30 psi tune anyone??

I'm pretty sure the turbo set up is totally different. Someone had even said they were sequential. I haven't had the time to read up on it though. I am really interested in the torque capacity of the transmission though. As these engines put out around 400lbs of torque stock!

Sequential bi-turbo. Little one for low rpm, quick spooling; big one for serious power.

Someone said 30psi.. Sounds like a stretch but it's obvious the Tranny already can take an enormous amount of stock torque, but anything in the close to 500 torque range would be brutal on traction and without the topend HP - I can't imagine beating 335i drag records.

as Dave_3 said, there's already been 2 years of development in the UK for the 335d. There have been plenty of back to back tests on road and track. The latest one had standard, press cars and tuned versions of 335i and 335d, and around the track the tuned ones were identical in lap times. So no, nothing in it at all reallly, although there's not as much tuning products available (exhausts etc)

It's pretty cool to read this time capsule thread. The 335d's are now hitting the 11's and 385-395 hp is easily obtainable with about $3,000 of goodies (turbo-back 304SS exhaust, intercooler and intake tubing upgrades, new tune) or for another $1000(upgraded fuel pump and airbox) 410+ hp achievable. Torque is limited to what the transmissions can take. Lots of guys at 625 ft-lbs now.

When they figure out how to increase RPM's (it will happen), you gassers better watch out

Bang for the buck can't be beat, is all I'm saying. I think gas version cars will always be faster ultimately, but with diesel we can have our cake and eat it too. Nice to have mountains of torque for passing power, and not rev the shit out of the motor. I call it stealth power--I pass people before they even suspect I'm trying to.

Edit: and we're waaay past 30psi tunes, lol. Stock is 28.5, mild tune is 33-35. Hot tunes can go higher, but not much point since we're more fuel-limited.

LOL. Yeah I was doing a google search for something else and this thread popped up and made me laugh. Cutting edge on the 335d's is 465-480 hp with custom turbos and custom injectors. But then that's a $6500 rabbit hole I don't want to go down.

Surprise suckas! LOL.

No need for custom injectors to get to 480hp...hybrids and meth should get you there. Although the stuff whitbread and a few others are working on right now is next turn of crank
