Dear All,

I am selling my customs camshaft from my BMW Z4M.

We designed these symetrical camshafts for stock pistons and Vanos.

We measured 28hp with Stock engine with tune and header.

Now we are at 445hp with this camshaft, only with a new volumetric ratio and some other minor modification...

Let me know if you are interested

Cheers!

[zurus]

Going to need more than that for potential buyers. Dynos,videos, pictures? Also do they work with stock rockers or you need DLC coated ones?

[comics69]

yes i understand...

it is working with OEM rocker.

We designed these camshafts for a stock engine, and we found it after many tests the best results in hp and torque.

Please find below the last dyno sheet.

Lifters? Springs? Fueling? Tune?? Intake??
Are these the actual ones your selling or are they copies of your one?

[dre99gsx]

Confused here. Z4 Automatic M 3.2 non-turbo/supercharged engine, and your reference before the cams was 375hp (I assume that is not wheel hp)? How is it so high before you even add the cams? How did you get from 330 stock to 375?

Also, was unaware that cams can add almost 30hp on an S54. Crazy stuff!

[comics69]

i am selling the actual one.

These cams are adapted to OEM spring, lifter, rocker as they have be designed to be not agressived for the head parts.

But please note that the current 445hp have been reached with several modification (titanium springs, DLC coated rocker....)

Here is the detail:

We first measured the car at 302hp (engine, not wheel).

Then we make tune, replace some faulty sensor, and get 336hp stock.

we later added some header, AEM Ecu, camshaft and get 375hp with bioethanol gas (368hp with gas "sans plomb 98").

Then, we build customs velocity stacks with watermethanol nozzle, work 30h to develop our high flow head (with new volumetric ratio due to very high compression ratio), replace spring by titanium double springs, lifter, rocker, and now reach more than 440hp at 8150rpm.

Now the engine with future new reinforcment (customs rods and pistons, reinforced rod bearing, vanos delete kit) should be able to get a rev limit at 9500/10 000rpm and reach more than 500hp in N/A !!!

That's it guys ...

Please feel free to ask every question

[mpathic]

Do you have OBDII logs for the before and after?
Dynos are great for a single engine. MAF flow increases relate to a more constant predictor of what increase can be expected, independent of the other mods.
Example is that basic exhaust and intake mods from before the MAF sensor and after the cats increase my stock S54 from ~220 gram/second up to 257 gram/second, at ~7500rpm. 257/220 = 17% MAF flow increase. That equals ~8.5% power increase.
That 8.5% number can be applied to any S54 that starts with a stock intake and exhaust, independent of what that particular engine might dyno at.
So your dyno charts are nice, but not relevant to me as a potential buyer because they reflect other mods and changes whose effects aren't known, rather than a true A:B comparison of stock engine vs only your cams installed.

[comics69]

I totally agree with you dude. I will try to share the log.

But the fact is that i don't have any interest to sell cams which does not have gain effect...this cams are the result of some development and test....

You can trust me

[Vanne]

Lol will you also provide the tune thats required to run these cams? And the fuel metering etc.. mate you should be selling not just the cams, but the setup. Otherwise there is no way anyone can use your custom cams. Please sell us your setup

[comics69]

I think you did not understand...

These cams are compatible with normal gas, and requires only a tunes as EVERY camshaft.

So with a stock car, there will be no problem...but for a better result, i advice you to get a decat exhaust, and a better intake (gruppe M, or other for better flow).

I detailed the different step in my previous post, take a look

I forgot another step : we reach 390hp with ONLY customs velocity stacks, cams, bioethano gas, header and decat.

The cams are only a part of my project, but they can properly work without any other major modification...other step are here to get more gain, and have been made in accordance with the cams, not the opposite...

Now we are developping other more agressive cams, which are not compatible with stock engine, so it requires for us to modify exhaust, new velcocity stacks flow...

Do you undestand what i mean ? The cams which are currently for sale WORKS for your car, only a tune is required dude...

But if you want, i can also sell my customs velocity stacks, which give great result with this cams

Let me know

[comics69]

i can also perform remotly the tune if required

I'm more interested in the AEM infinity harness you guys did.

[Blakkflame]

....where are you located, exactly ?

[dre99gsx]

Is that horsepower chart engine power (taken on a engine dyno) or wheel horsepower (on a rolling chassis dyno)? I believe you will get quite a bit of skepticism on the capability of those cams in that, at least here in the states, guys who supercharge their S54s don't even always achieve those numbers, yet you are doing so with moderate upgrades to a naturally aspirated engine, and presumably through an automatic.


I'm not sure if you are a full blown engineering facility which produced sought after performance parts for S54s, and pardon me if you are, but in my history of doing camshaft upgrades, 50-70hp increase would only be realized on heavily modified turbo charged vehicles.

You have leading competitor cams like Shrick and the likes, who don't even come close to those figures. Not to derail your for-sale thread, but if you had other folks with the same camshafts seeing similar results, especially here in the states, you would probably have much more luck in selling these!

I can make it for you, but as i told in another thread, the ECU Pin connector does not exist, so for building a proper harness i need either your ECU or another one....

Let me know if you are interested

First of all, my Z is not an automatic, it does not exist.

The dyno sheet are taken from our Bapro dyno roller, and the hp are given at wheels.

I think you did not read properly all my previous post...

Currently the car is measured at 445hp, but for a such result there is a HUGE engine development, not only the cams dude....

the cams helped me to win 25/30hp from the beginning, now the car has a customs head, customs velocity stacks with watermethanol, an AEM Infinity ECU (CAN compatible), customs exhaust, reinforced rod bearings, new volumetric ratio due to the very high compression, and bioethanol gas....

We worked at least 3/4 months at the development of the engine, and measured our gain on dyno.

I don't know how i can explain, the best way for you is to come at our workshop try the car

Can you share a pic of the velocity stacks please?
