i have only read 1 or 2 of your posts,
but imho i think u need to move to sea level. i think you could use a little more air

Saw the 135 today, that thing is impressive. I'm sure there will be pictures and video when everyone gets back from the track.

Give it a rest man. Put your $50k car on the dyno and let's see if it blows up or not on pump gas.

I'm personally only interested in pump numbers too but I don't hold it against Abid and Shiv wanting to run race gas initially to 1) keep as wide a safety margin as possible tuning in uncharted territory 2) let them have their 15min of glory.

Both parties put in a lot of time and labor (and $ in ASR's case) and we're just spectators. Give a little respect for those working hard to make replacement turbos a reality for everyone.

We talked to Shiv about this today and that was exactly what he told us. Tuning with race gas first was for safety. Very easy to blow things up on pump gas. The pump gas tuning starts tomorrow.

We did do some pump gas runs before race gas to empty the tank. We were able to average 425-430whp with no meth and no fine tuning. We will finalize pump gas tuning tommorrow along with pump/meth and race/meth. The turbos will have no problem making 500whp as long as the ignition system doesn't blow the spark out first.

Are you experimenting with plugs (temp ratings, gaps, etc) during this process or just going to stick it out with the stock ones as originally equipped?

that 135i is sick, i have to give abid and the asr team props on the car. Can't wait to see the final numbers and have it officially released.

Good luck Abid.

1/ what do you plan on doing with the 6AT with respect to your upgraded turbos ??
2/ are the manuals and auto trannies going to hold up?

i am not a worry wart, but i would rather spend reasonable sums to insure my tranny or other parts do not break with 480+ whp.

my 2 cents

425 WHP with pump gas?

My car with just bolt ons and race gas made ~410 whp.

So it is hard for me to justify to buy a turbo kit that will only add me another ~20whp for 8-10k (which is my assumption of ur price).

Also isnt the setup for the 135i and 335i different in the way the engine bay is setup in relation to fitment?? Any reason u guys didnt do more homework for a new fuel pump which is entirely needed to make big power??

also I am assuming u found the stock fuel system max's out at 465-470whp so that is the roof for this turbo kit with race or pump??

Bob,

It's too early to judge. Also if you look, they talk about having a new fuel managment system:

Well I think when you spend top dollar for a turbo kit it should look and utilize the majority of the OEM system which the piggyback is not, piggybacks are kind of old fashioned. Also a inherent side effect of a piggybacks as is that it only alters or tries to simulate the signal the ECU sees and never changes the actual programming, just attempts to manipulate it. The manipulation can only go so far as most piggybacks alter just one (at most a handful) of signals at certain RPM points and not necessarily the array of load maps the ECU relies on. With today’s ECU’s, signal modifications confuse the ECU’s learning mode often resulting in poor drivability. Also, direct changes in one signal may also trigger indirect changes elsewhere which can lead to undesired consequences. If you have the technical ability to properly adjust the factory ECU, there is no reason to falsify its input signals with a piggyback.

This was all true circa 2005.

I'm waiting for the final results. Right now they are testing and getting out the kinks. Takes time. You just don't plug things together and expect it to work right out the gate. Also the HP figures they have hit are across the band, not a peak at a certain level. Much more power throughout. This should be good. I'm just waiting on the price. As for flash vs. piggyback, who cares. In the end, it's just getting the CPU to do something. Makes no difference how. I'd rather have a piggy as it is easier to remove if I want later and it is something I can easily do myself.
