Small example of why GC Lites are the best Sub $3000 hybrid option on the market

[dyezak]

How do these go in less than ideal conditions like customer cars? How reliable are they?

Heh, these are less than ideal conditions (look at the log) and is a customer car.

Is this e85 or 93 octane
gas?

Car specs:
2007 E90 N54 6MT

Tire shredders. 600wtq at 3k is pretty nuts

I’ve got a 335d (Diesel) making 600+ wtq at 1,200 rpm

 

[Tony@VargasTurboTech]

Its also got a 5K rev limit, and power is falling off way before 5K. So we have near diesel tq production, and peak power at 6800-7000RPM. I’LL take the gas motor...

Actually - I make almost all of that tq to red line and trap 123 in a 1/4. And get 35 MPG while BEATING on this car with hybrids.

After I’ve added the new cams and forged rods/pistons, EFR LP turbo, raise the rev limit to 6k - 650 whp and 750+ wtq is the target.

That is pretty crazy. Has anyone ever broken the 6hp28?

We have the ZF tranny. No one has yet - and I’ve BEAT on the car.

I have a spare trans in my barn - plan to build it to handle significant power if/when it goes.

I have a 6hp28 also that I was going to put into my car and never did. If you know someone who wants to buy one LMK lol.

The N57 is the second best kept secret, next to the Z4 N54 weight and low CoG making it the sleeper BMW tuning platform. My daily is a 535d. With the right suspension mods it handles great as a daily, stump-pulling torque, when tuned, and can be made to look bad-ass with a handful of bits. 36.2MPG averaged over the last 6 months. Way better than the N54 Z4 for everyday driving, and let's the Z4 become the project car with brutal behavior.

Eventually, and we're talking maybe a year or two away, I'm going to buy either a Z4 or another 335is, and do a N57 6MT swap into it. 40+ mpg, and power to boot.

The problem is tuning significantly lags behind N54 support.

Yes and no....several tuners now supporting (and pushing forward) the M57/N57 platform. Most have hit a limit of 500 whp and 700 wtq because of cam profile and back pressure issues.

The M57 is about to make a HUGE evolutionary step forward, similar to when the first ST was made for the N54. My car will be north of 650 whp and over 750 wtq as I am solving the above issues, and adding a custom EFR LP turbo mated to my HP hybrid.

Any way to get rid of the autotragic trans software so it'll run with a man pedal? That's more what I meant when I meant tuning support.

XHp flash trans tune is great for the M57’s - and a guy from another forum is writing custom tunes which are even superior. I ran the NC 1/2 mile back in May of this year with the xHP tune and I was very pleased with how crisp and sharp the car felt in S mode. FWIW - I put 15 car lengths on a tuned F80 M3 in one of those runs....

The guy I’m using for the 335d and 135 build has actually made a manual swap kit for the M57 - but I can’t afford that at the moment...

How did this thread turn into a Diesel discussion.. I actuall love diesel's we were a diesel shop for many many years. I have just worked on a few of the M57's, and they were such a nightmare, I swear I would never own one.. Kinda making me rethink it...

Once all the emissions shit is deleted - these are incredibly reliable and stout cars. I’ll just leave this here....pulling 5 cars in a CTS-V with headers, Cam, tune, and smaller pulley.

Looks like the CTS-WannaV didn't do so well.

Bad-ass purple squirrels. You know you want one.

I have a video of a diesel putting about 15 car lengths on a tuned comp package F80 M3 in a 1/2 mile from a dig too

I’ll not hijack this thread any further - return to your normal gas related conversations
