First after knowing Gavin as long as i have he is not going to sell a product that is not reliable. Second if you have been following his SC thread from the beginning of Day one, its taken along time to just get to this point. It would be dumb business move for him not make sure it reliable and if something went wrong it would be all over this forum and everyone would question his SC.

But this is also depending on what issues comes up. It's is a piece of machine and shit happens. But I wouldn't be surprised if he had a warranty on his product. I think before you start talking shit about reliable and the pipe dream. Which the pipe dream is working and running in his car. I think you should shut up and wait and see how the product turns out and what he offers to people.

Also for not owning a 328i you should stay in the 335i forum were you belong. Since you don't drive a 328i I think your option really doesn't matter.

Just my 2 cents to the 335i trollers.

How much more work to use 6 larger injectors instead of the additional injector setup?
Gavin,

Any input on the expected power figure or is this a "wait and see" thing?

Welcome to E90post! Check the AA thread. A real Q&A would include 10 questions at the most. And it keep going for dozens of pages.

Cant wait to hear a end-user review of this.

He has just as much right to speculate on it being not reliable as you do to speculate on it being reliable

Lets be fair about this... there is a lot of history that does create doubt, so lets hear out those expressing concern and not run them out of town

There's a difference between expressing concern and making baseless statements.

Pretty sure all statements beside's Gavin's are baseless at the moment, just my opinion.

Then again, I probably won't trust this until some reliable 3rd party reviews come up.

Don't get me wrong, extremely excited to see it happen. Just trying to avoid the whole mob mentality thing again.

Are the headers required? What do you lose if you don't have them?

Lastly how much weight does the full kit add and what does it do to the front/rear weight balance?

Any change to the minimum AKI/octane gasoline that must be used?
That's a tough question to answer really, because the N52 N/A is very reliable, as a lot of us know there are guys close to 200,000 miles with repair bills that are nothing to scream about. Also the 335's have had some problems as we all know, take a trip to the 335 section and there are plenty of things that happen to them, but most of those guys are tuned and things naturally go wrong when you push the limits - in any car.

You guys all know this car is my Daily Driver (when its running obviously) and I dont want to lose that aspect of the car at all. Once the final variation of the kit is done coming up in the next week - I still wont even offer it for sale until I get to do more testing on it. As it is right now, I have ~2500 miles in it with the 90% kit, and the only issue I have is on cold starts - the idle fluctuates for 15 seconds and then it is fine - but keep in mind im still testing and its not the 100% version yet.

The blower we use is a Vortech V3, it's self contained and has it own lubrication, which means that it doesn't share hot oil with the cars engine, it keeps a lot of its heat to itself. It's 93f out here today and i was sitting in traffic on the 405 freeway idling without issue, heat never went outside of regular temps, and the engine fan keeps everything working fine. At the stage 2 kit, we will add meth injection and are looking in to air to water cooling at the manifold. so when the time comes to push it, it will be well within a safe temperature range still.

I don't have an exact weight difference at the moment, with the headers I would assume about 40-50lbs split evenly over the front end (half for S/C half for headers) but i will make a note to check into this accurately when i get the chance.

Octane, 91 at least. it will run fine on 91 all the time, it's a low boost kit and is meant to be daily driven and user friendly. I dont think finding race gas for your trip to Vons is user friendly. In stage 2, running 7.5psi it will still run on 91 just fine in the case your meth tank runs out, or you just dont want to run it. I like meth because it keeps temps way down, you can even use -30 windshield washer fluid as a perfect mix of meth, and its like running 100 octane all the time for $3.

the 330 should be in the upper end of the 350 range all said and done, but I would have to test it out on one to know for sure - Haven't got to that point yet

On the 130i in AUS - obviously I dont have a test car for this, but there should be no reason the 130i wont hit the same numbers as a 328 or 330. 265kw is about 355whp - which might be a few on the high end, but 250kw + i can see happening for sure.

Lol, the amount of R&D in the headers alone is far beyond that of the few sets that were preordered, if I lump in the S/C kit too - the cost is exponentially more.

I know we are waiting on the headers, I'm surprised it took 4 pages for someone to bring it up - but the set I have is the first finished article and all the others are coming right up behind it. No one else has any designs like either of these things, and no one is even close to making them happen. The headers offer 2 setups in 1 set. You can run OEM midpipes, or you can step it up to a 2.75" and slip on direct from the headers, and then go back to the OEM midpipes whenever you feel like it, without welding anything. That cuts down install costs and custom exhaust costs. Why someone would make a high flow header and restrict it to a OEM size flange defeats the entire purpose of having the extra flow when you need it. Then add in ceramic coating.

Honestly to me I think an SC on a N52 is going to be badass. I know to that to get the full potential of the SC certain mods like the headers and full exhaust will need to happen in tandem or else it would be a moot point. I drive a 328xi and going from 230hp to 325hp or more would be sweet.
Can't wait to see the final product!

I totally agree with you, this is gonna be sweet when it comes out. I do have to make a correction though, because people won't bother to look back through the thread or spend the time investigating this themselves.

Quote:
Projecting 320-350whp all said and done with headers and final tuning.
from Gavin, however you quoted from 230 to 325. The 230 is at the crank, as when dynoed, depending on which dyno it's on, the stock 328 hits around 200whp, and it's spec'ed from the factory at 230bhp (brake horsepower, more or less crank horsepower). There is supposed to be about 10-15% HP loss when going from bhp to whp. For reference, the stock 335i comes from the factory with 300bhp (assuming same loss % as a 328 [14%], ~258whp stock), and the M3 comes with 400bhp (assuming the same loss % as a 328, 344whp; 2011 numbers, easiest average e90 of this generation to use I believe).

So the 320-350whp will convert to a higher bhp, so it'll be like a 335 with mods/tune/etc.

I'm even more excited now after doing the math!

That's an N54 on what type of dyno?



The car is back in the ICU, going under the knife for the final parts and finishing up tuning, then I will have specs released and dyno charts to check out also.

Im focusing on getting headers wrapped up and shipped out in the mean time
