Horsepowerfreaks Ethanol Z4M build

There it is, the build has started...

I will use ethanol instead of racefuel.

I have received these today ....

Awww yeah. Happy holidays to whoever gets to drive that!

Looks great , horsepower figures on the injectors are off though , BSFC is for gas and sheet is for a 4-can setup, id say those injectors are capable of around 600bhp

i thought thoes numbers looked a bit omptimistic also but i wasnt going to mention it as im no expert

Actually at 5 bar rail pressure those should be 1440cc injectors. And on e85 should be good for about 1000-1100 flywheel hp or about 900-950 whp. (max duty cycle) remember e85 makes about 11% more power with no added timing or boost.

I'm running those very same injectors and have made 850rwhp with them.

Thanks for the info, Jason personally recommended these injectors so i have no questions about them.

Oh yeah i was thinking static 3bar pressure, dont forget e85 needs 30% more fuel , so an injector that flows 200hp on gas only flows 160hp on E85
(note i said a 4can setup as that what the sheet specified)
Also running them at 100% DC isnt recommended , i try to never get above 80%
Even though newer injectors are less prone to failing i've had bad experiences in the past cap'ing the injectors

yeah but e85 makes more power so its not exactly counting apples to apples as far as fuel volume and power. Id say using your example if gas flowed 200hp then e85 would be closer to 175hp but thats just me bench racing.

What i mean is at the same power level E85 will need to flow 20-30% more fuel to run at lambda 1

I think we're arguing ove the same point , just my translation capabilities are messing it up

I have those injectors also. How many cc are they?

Great, they are 1100cc.

Final pics with iphone i will use my nikon from now on

Looking good!

I'm excited to see this come together!

I want to have sex with your sterring wheel

Thanks, i hope one day you will make a equal length tubular exhaust manifold kit for s54.

This is pretty nuts. Lots of money, but this is going to be sick.. Looking forward to it.

Shoot me an email, Andrew@lutzperfauto.net and I'll forward you to Shawn our Fabricator and see what we can come up with

Thanks!

Basar.... Completly unrelated but i love the black hardtop on you grey roadster.... Id like to do something similar......,, any more daylight pics of the exterior of your car???

Im guessing it looks even better in person.... Its really unique.... I will be doing thr same with my ti z4m r
