Do you test and have a fuel pressure sender/gauge and the end of the line /at the connection to the HPFP? Maybe it is a combination of lpfp/voltage and fuel line/too small. Having a pressure gauge at the end at the HPFP entrance will show if you are losing pressure anytime.

Glad to see this type of testing going on. It will hopefully provide a good upgrade path for the future. Fuel upgrade + RB turbos FTW!

The best fuel upgrade and one that would guarantee over 500 rear wheel is standard port injection - oh, wait did I just say that?

Plus 1

It's called a 2 inch spacers Btwn the head and mani tapped for 6 600cc injectors. Let the di do its thing and have the pi turn on at over 15 psi

Based on my experience with DI, its the hpfp that is out of steam, but hell maybe you will proove that to be wrong.

Terry's been working on a lot of things so I am glad he had a chance to get us some useful data. In the end it all benefits the community to get as much data from different sources so we aren't relying on any one piece of data or opinion to move the platform forward.

I think I am going to have to have a beer with you if I am ever in your area as all this cordial communication over the last month is a refreshing change

NOT for long though! There is NO way it can handle that kind of power. Its rated by ZF at 295ft/lbs maximum input torque. The third gear clutch packs gonna take a s**t real soon.

Maybe I dont understand the rating, but thats less than the stock engine's power?

I think they mean max torque at the converter. Either way its no where near 500ft/lbs, which is what hotrod182 had, when he blew out his.

[Jeff@TopGearSolutions]

The numbers pretty good but I wouldnt drive that in that trim, way too lean for my taste and I understand the DI can run lean but 13+ AFR in some fat ends with that much power puts shivers down my spine. Good to see the ignition is pretty solid at any rate.

On to finding more fuel!

Blew it out? Didn't it just go into some kind of "limp mode"?

It's a risk for sure but LM is aware of it. He's doing track testing with it today. I smell a new 335i record if the motor holds together?

Not if you call falling out of third gear back into 2nd at 8,000rpms, normal transmission behavior. The video of it is on youtube.

Def not normal. But car ran just fine after IIRC.

Wrong the torque converter is rated for 295 tq. Being that the torque converter is locked at wot, this is a not as big an issue as you think.

lol, you had a beer with shiv and you still fight like little girls.
Give me a week or so, ill find something to bitch about lol

[rismo]

Fyi my gearbox is dying....

Never been pushed when not warmed up till 90c... but since a month of 4 the gearbox is making noise upon increased load / acceleration.
It does not lose oil, but the only way to get rid of it for a moment (1-3 months) and the moments are getting shorter is to refill the oil.

It's seems that the torque generated by a tune can harm the AT gearbox.
I have 140000km on the clock.

Currenlty looking into getting the box overhauled and finding away to make it more capabel of handling these amount of torque.

Any suggestions?
