Article: Horsepower Freaks Right Hand Drive (RHD) E46 M3 (S54) Stage I twin turbo kit officially released - $18,500

[Sticky]

Branden,

why dont you or your stage 3/4 customers measure 60-130 times?

with the 345 tires and big wing you should have good traction.

Waiting forward for your 60-130 times.

How do you know how much faster is a stage 4 compared to stage 3?

new stage 5 will be faster than stage 4 but how much?

Please do measure the 60-130 times.

Mert, they list 60-130 times for their kits in the print advertisement for them. I don't know of any other company that does this.

So, they pay attention to it and post their customer's number but they do not actively sit around and try to have the fastest 60-130's around.

Plus, this is a thread about a new release not about 60-130 times, ok?

Funkboy,

there is no repair, no damage. There is the S54 B36 in my E46 M3 now, excitement.

I have built a 3600 cc stroker engine, a custom S54 B36, will be tested once the brake-in is over.

Custom crankshaft, custom rods, custom pistons........this has been a joy and excitement.

If you can contact tell your stage 3 HPF buddy in Istanbul to line up with me. Will be fun to
test my 3.xx second M3 vs. another turbo M3.


Sticky,

They do exhibit 60-130 on their site but the stage 3 and stage 4s dont have "VERIFIED" times. The figures are not verified, just stage 1 and 2,5 are verified.

I wonder what the stage 3 and 4 times are since a new stage 5 is coming out.

i still dont understand this fascination you have with 60-130 times, and i still dont understand why in the hell you think i know how to contact someone that lives in Turkey. its almost like your truly a retard and just lack the brain functionality to understand the most simple facts. I dunno, im starting to feel pretty bad for you...honestly

So they did rent a track and published their 60-130 times.

Mert, in a few months I'll start posting a number of videos that will be integrated with my DL1 data logger. I'll post times for various tracks I run on and if I'm able, I'll get the track records and some comparisons. Sorry but 60-130 times just doesn't interest me. Driving a BMW in a straight line is just gay man, the car feels insulted if it's not driven on a road course.

Come on, what do you expect from him? He lives on planet 60-130.

in a straight I drive my M3s, they are designed for 60-130 and 60-150 mph. At the track I drive my 997 TT, more grip than M3.

I think modifiying a convertible car is veryy gay. Convertibles flex, convertibles are 200-240 LBS heavier. Real gay choice. Converitbles dont have proper traction and handling.

Come on, what do you expect from him? He lives on planet 60-130.

If you could own a fast M3 you would be happy. You do envy. Keep on jealousing.
On this board/forum who would not want a very fast M3?

Yeah, my middle name is jealous-of-Mert's-m3's.

[Mikecoupe]

Enough with the 60-130 crap

This guy is realy sick,in every thread he is asking for 60-130 times

Mert - how about a 200 to 0 test? I heard the best way is to use a brick wall. Post it up!

you act like you know a lot, why would someone use a boat to modify? A 4 door E34 heavy car?
I sold my E34 M5 cause it was very heavy.

Did you ever measure 0-60 or 60-130? Do you modify to just make fender vidoes?

Saw your homemade video showing the fenders. It is amazing......

My M3 has 2 seats, yours can take 5 people, so take 4 more people off here such as GG, Sorena, Commander and Funkboy and hit a concrete walll.

[5mall5nail5]

Fenders? I have never modified my fenders lol and never posted a video about fenders. Everytime you post its like baby bird trying to fly - you want to help it but you know you shouldn't so you just stare and watch.

That 200-0 with a brick wall went right over your head didn't it?

My e34 weighs less than an E46 M3 in stock form turkeygobbler. Eat it.

You should take a ride with these boys...

[Twinturbom3]

jun,
your go pro vid showing fenders...an artistic video....

did you weigh your boat? have you put it on a scale lately? how do you know the weight of my E46 M3? You dont. Just fix your noise issues and get the boat's 60*130 times.

[5mall5nail5]

I've been driving my car to work for 2 weeks now Mart. My name isn't jun you derelict. I also said a E46 M3 in stock form. Know why I didn't mention your M3? Because NO ONE GIVES A $#@! ABOUT YOUR M3. EAD.

[Commanderwiggin]

Just move all Mart Densmans posts into his own polluted thread...he clearly has a mental problem and we can clearly see that has been getting worse over the past decade...he needs to be put asleep...kind of like his M3 is most of the time with rebuilds lol.

With how fast he is losing rep he won't need to be moved anywhere soon. I hope he figures it out.

I posted this on another forum, thought it would interesting info to add here as well:

"The turbos aren't too small, they just don't fit this engine properly from a flow perspective.


The exhaust housing is not a big restriction, there's still more left in it before it chokes. Corrected mass flow choke point is about 15 lb/min @ a PR of 1.8, which I'm guessing is pretty close to what these turbos are running at on pump fuel. That's 300hp worth of exhaust flow per turbo...which they aren't doing yet. So in this case, we are not "turbine" limited.


Looking at the compressor housing, it can flow a bit more than what is being used, but you need a higher pressure ratio to tap into that.


The issue here is that the compressor STARTs in the middle of it's efficiency range at 4000 RPM which is 76% adiabatic, progresses through 78%, then continues to decrease down to about 65% by redline. In layman's terms, the engine is too big for this turbo. The compressor needs a little bit more flow potential to match the airflow requirements of the engine.


If I was designing a twin turbo system, I would have the target airflow at peak torque fall on the left of the compressor map closer to 70% efficiency, so that as RPM increased the airflow would walk "through" the highest efficiency band of the compressor. The way it is, it's starting the middle and dropping off as RPM increases. On the dyno chart, you could gain another 10-15% at peak power just by matching the compressor side better at the same pressure ratio. (Manifold pressure would be the same, the air flow would just be denser)


Now I'm sure every will say "Just get a billet wheel, and all will be good". That isn't the case, as testing has shown that the new billet wheels make power on larger frame turbos, and that the gains in efficiency scale down as you reduce the compressor size and increase compressor speed. Billet wheels aren't going to solve this issue, the size of the compressor wheel will. In this case, a custom wheel (probably billet by design) and cover would be the solution without having to re-design all the supporting hardware that HPF has built.


BTW, adding meth would help the situation a little bit, but it's not going to change the shape of the torque curve dramatically.


Just my opinion."

So essentially you do not feel the proper sized turbos are being used?

[PEI330Ci]

So essentially you do not feel the proper sized turbos are being used?

It's not as simple as it seems.

Compressor maps don't take into account everything that the turbo is attached to that affects it's performance. You can theoretically have a great match, then find that the VE of the engine is different, and it shifts the operating range off the edge of the map.

I'm not going to point fingers, but I know of one very well respected builder who is touting very good numbers from a car on the dyno, and I've found them technically impossible to achieve based on the compressor map. You just can't get XXX power from a turbo if you've got it operating far to the left of the surge line at X.X pressure ratio. I know...I said left of the compressor map....that's what makes it so strange.

Anyway, all I'm getting at is that HPF has probably been excited about getting the RHD system finally working, and has gone a little bit ahead of the normal R&D curve in releasing the kit with only dyno testing under their belt. There will be revisions and changes that I don't doubt will make the LHD guys think twice about the single turbo kits. Chris is a visionary and reads the market exceptionally well, I don't think he's got it wrong in this case....just a little bit "off".

I think he has gotten it quite a bit "off" without realizing. The LHD cars have been doing the marketing for all potential RHD owners. They have built in their mind that type of power level and the various staging going up to pretty high powers. They then release a 500whp kit that is at its limit and undersized for the S54 and start marketing it as a excellent package for track use etc. A lot of potential buyers are disappointed with the outcome, I personally know of three that where cash in hand. The error was that the mid frame turbos should have been used as a start point even if it meant many more months development. Sooner or later the customer with the RHD car at HPF is going to want it back and that will be the end of the development for the RHD cars.
