Ignition for big powered (more when 800HP) audi 2.2 fuel E85

[FCP-ENGINEERING]

Hello,

Need some info about ingnition for big powered Audis more when 800hp. As you know E85 not very flamable so we have problems to make perfect fire. What coils you using and ingnition type. Thanks in advance.

Well 800 hp is a LOT of hps. In addition to brand new stock ABY/ADU/AAN ignition system (POSs and coils), the four ignition systems that might work include the following:

1. 034's HO coils

2. EFI Express's LS2 coil kit

3. EFI Express's LS2 coil harness with these coils

4. Hayabusa motor bike coils that I think Hap Maguire runs on his "Green Monstah"

Do you ever heard about CDI ignition from company M&Wi ignitions?

audi stock 2ltr tfsi coils works as well

Yup, the same coils are used in Lambo engines...

And the R8 engines. However, at 4.2L and above, their specific hp ratings are MUCH lower than the goal of 800 hp out of 2.2 (or 2.5L). I doubt that the coil-on-plug 2.0L TFSI coils would work at the necessary high boost and fuel levels required for 800 hp from an in-line 5 20vt.

Only one way to find out...
I guess in this case it's the E85 as well.

Well, perhaps there is someone with BTDT experience on this who might want to chime in.
Repo?

i do agree with that. i think LS2 will allow for higher charge time of the coils as well without risk of burning them.

Maybe im wrote not clear 800hp we have with no problem, but we going for 950-1000hp.
Using CT43-7475 Billet Race Turbocharger and 2500cc injectors and E85. On 850hp we loosing fire.

Which ecu ?

A mate of mine did 806 whp with NiRA and normal 1,8T coils...

Well, in that case, I think what you will need are five reactor-on-plug set-ups like this one:

UrS4boy.. LOOOOOOOOOOOLLLLLLLLLLL HAHHAHAHHA you are crasy...

CDI ignition are so STONG that I think they can work without fuel.. (just kiding) , but I soo how they work on ABY engine (around 700 hp) , the lighting from spark can jump 50-60 cm , guy hold the spark wire maybe 50 cm away from engine , and lighting jump on intake manifold.. it is brutal .. lihe the tunder from sky.. I could not beleve it could happened..

if you have problem with that CDI will definetly fix your problem..
