Nobody has found an even more optimistic dyno yet for a new WR? I'll hopefully post a "delta record" soon - should not be difficult to beat but just to change focus to something tangible.

More coming soon

Were you able to get an e30 ots map?

whats done to the car
Full bolt ons , Bootmod3 , Snow performance VC 50 meth controller , 93 oct , and 100% meth!

What is Bootmod3 map?

What kit were you originally using?
During that dyno (446whp), sounds like it was charge pipe injection kit? After your upgraded turbo you went direct port?
I see the controller was snow so maybe that was the entire kit you used.

Thanks

This thread is like 5 years old man

Nice setup and numbers I wonder how much power I’m making on my 435i with
Upgraded charge pipe
Vrsf intercooler
MHD stage 2plus
Catless downpipe
CTS Intake

I’m
From Australia running 95ron/91oct
Would I need a hpfp to get to 400hp or close to ? Or is it not worth it unless I upgrade turbo ?

If you dont have E85 you dont need a HPFP on stock turbo. You are octane limited and a HPFP will do nothing for you with 91oct

I’ve been told I can run e85 on stock pump 435i F32

You can run E85 up to about E30 (30% ethanol in the tank). Above that will exceed HPFP flow capacity. It's not an incompatibility issue, its a fuel supply issue.

MHD offers two different E85 maps, one that is dedicated for the stock HPFP and one for an upgraded HPFP. Either will work and not cause an issue, just choose wisely according the the HPFP that is currently on the vehicle.

It's not the ethanol % content that limits the fueling, it is the aggressiveness of the map/tune.

Huh? How much E% is in the fuel will determine whether or not your HPFP will crash.

It goes without saying that you should select the correct map for your hardware. But even if you select the correct map if you run too high of an E% in the tank, the HPFP will crash.

OP specifically asked about stage2+, so lets say you run the stage 2+ E20 stock HPFP map on MHD. Then you put E40 (40% ethanol) in the tank. Your HPFP is going to crash. MHD maps have a little headroom compared to BM3 maps, where you can get HPFP crashes with cold temperatures or slightly overshooting the E% in the tank above 30%. If you have been using MHD for a long time you may recall it used to actually be an E30 map, which they later changed to E20 to give more headroom. If you look at the website there is still a typo as it reads: "Ethanol Mix Maps: Stage 1, 2 and 2+ E20 Maps for ethanol blends of 30%" https://mhdtuning.com/products/mhd-s...icense-for-n55

So it doesnt matter if you select the stock HPFP map if you put too much ethanol in the tank the HPFP will crash. The tune will determine how high of an E% you can put (i.e., based on boost target).

Take a look at your last sentence and my last sentence. You just typed out a lot of things for no reason.

[5w20]

Stage 1, 2, and 2+ full E85 maps available.

Stage 1 & 2 for stock hpfp.
Stage 2+ for upgraded hpfp.

It wasn't really for you, it was for OP. Based on him being a new member and his questions it was to explain how you need to pick the appropriate tune for your hardware and make sure your fuel mix is correct.

I get that your interpretation of his post was a literal E85 map (85%), but when the majority of people talk about "running E85" they are not talking about a full E85 map.

I'm not arguing with you or disagreeing with what you are saying MHD offers in terms of map options. It's simply providing the context and other information for someone who is new to running E85 maps. So it's not for "no reason", its to be helpful to someone new on the forum.
