breaking into the 400whp barrier soon?!

He has "upgraded" turbos, dp, ems and intake. nothing said about the fuel management nor block yet. i hope its true since so far i have only heard about 1 actual 335i (wheel boutique's) turbos being changed out . what do you guys think?

We'll be breaking 400RWHP with V2 Procede and downpipes only...no need for all that other expense.

You know for all the work he is claiming, the dyno numbers seem kind of low (He states that he still needs to be tuned, guess that could be it).

I agree the numbers seem a bit low especially considering that he has upgraded turbos but that's a bit vague...upgraded how? I think much beyond 400RWHP the fuel system will start to become an issue. Until someone figures it out I think we'll be stuck in the low 400 RWHP range.

He said he is running 'stock boost', so those #s are pretty good. Should see a lot more HP with higher boost levels.

"Broken" in the 400WHP range is more fitting lol.

You guys really believe we'll hit 400whp with just procede and catback?

I was thinking we *might* barely hit it with Procede v2, turboback, FMIC, and 93 octane, not 91.

440 at least with those IMO.

The skeptic in me keeps thinking that some of this could be dynofantasy. PROcede, DPs, etc. supposedly giving us 400+ whp, but do the acceleration times really bear out that level of performance increase? 25% power increase, but 10% acceleration increase at best. Some of this could be traction related issues -- we need a properly set up 335 with LSD, suspension, and wheels/tires to test what the real world gains are from these engine mods.

The poster on that thread is a bit vague. Upgraded turbos?!?! What turbos? How about a model number, give me something? That would be about a $3k upgrade alone for just those.

Really need more technical info on this setup from the claimed exotic tuner in the link he provides.

I don't think anyone said anything about a cat-back but I'm pretty confident V 2.0 and downpipes will put us there. I'm at 340+RWHP and over 400 lb/ft with just V 1.47 and nothing else. I don't need cats and cat-less downpipes are basically good for 30 RWHP so that puts me in the 370-380RWHP range so another 30 RWHP from moving to V2 will put me in the low 400 RWHP range. A full exhaust with V2 and I'm betting I could lay down 425 RHWP but I want to stay stealthy. I like it when people think they're picking on a 'poor little 3 series'.

Correct me if I'm wrong but isn't the 4g63 the engine and not the turbo?

Sorry for the bad quality video....I saw it long back....maybe from a diff link....the video was much clearer in that. Anyway, in the end the ev0 with gt35r turbo catches it pretty quick!

Titan will be modding a car and doing some stages here shortly as well.
