anyone get ess vt1 supercharger kit installed?

[stevenzx]

the ess vt1 kit seems to be a big new to n52 1er. any us owner tried it yet? i am in china, and want to get this done as soon as the the money ok. 300 whp is really big thing for n52 owners here!

I think a few folks on E90post have had this done. I don't recall any 1ers getting it done. I believe that the main concern was that it's pretty expensive for the gains you get.

yes. thats not cheap, but 100whp is lots of power for n52. ess sc will take e8x to the next power level.

[Swimjim]

big concern i have read has been can the n51/52 handle the increase? durability? why not just trade in the NA for a 135?

whats the point of having a 300hp 128i, when you can get the 135i with 300hp stock???

Just going off BMW China's site, a new 220i starts at 57k USD. M235i starts at 84k USD. Maybe that has something to do with it.

Used 135's are not that much though.

How much then?

That's a lot of drivetrain loss, most likely found in AWD; 135i's dyno around 280whp (hint: underrated). Also, you got nitrous?

The problem is the injectors.
Thats the only thing holding me back, I hope they solve the injector issue, when we can run more boost, it will make this kit wayyy worth it.

I don't think its 100whp. It say 60-70 whp on their website -- http://www.esstuning.com/products/ES...er-System.html

The last dyno day i went to stock 135i and 335i's were putting down consistent 240rwhp runs. I put down 220 runs consistently(modified of course). This was all on a mustang dyno.

Also the kit doesn't give 100RWHP. It gives more like 60-70rwhp before the injectors are tapped out.

You can expect just under 300RWHP with no headers(because of the injectors limitation) and the vt1 kit.

e90post has a much more detailed thread about all of this SC talk.

You cannot say that unless youve actually pulled the engine out for an engine dyno.
General rule is 15%......but it is only that, a general rule for RWD cars. Some chassis dyno operators will convert your WHP with magic sauce to boost their customers ego.

I mean, you can say your CSB is bad, and that you recently switched to Molly GearLube XYZ thats thicker and therefore your drivetrain loss is 22% and therefore you have 310hp etc etc etc

The only reason why this kit did not get as popular as it should is the injector issue.

But I'm just going off the forums and my own experience. Even if you say it's only 15% then that still only 255whp not 285whp. I just don't see a stock 135i pushing more then 240whp . But that's me. I have 281whp (dynoed) and I pull pretty hard on the 135i.

It's no secret the n54/n55 motors are underrated. This has been discussed numerous times on this forum. The lowest I've seen in person was 266whp on a stock n55 DCT 135i on a mustang "heartbreaker" dyno down here in South FL about a year back. The two others I've seen (IIRC these were on a dynojet) made in the 280's.

Never seen one make as low as 240 in person or online.

Careful, so youre purely basing your numbers on two assumptions now, a marketed number for a mass produced engine, and your dyno shop and his configs.

Trusting a shops dyno numbers is already a strech enough.

they say the oem injectors are ok for vt1 and vt1+. big injector will cost more fuel for sure.

there is only 130i and 1m in china. no 135i. btw, they have been tested this kit for thousands of miles.

yes, buyying a new model bmw is too expensive in china. 2nd hand one is also not cheap but ok for bimmer.
