Bigger charger ?? Plus Rotax ecu?
The time has come to get a bigger charger. I have many ?? Please help!! And thanks!
On my sig you can see all the mods I have right now. But I already have a Rotax ECU 8600 rpm, VTU and a speedfreaks rideplate this parts are ready to install.
What is the biggest charger I can run with this set up?
What size injectors would I need?
The ecu was map for 42 lb injectors can I run bigger ones with them?
What else would I need to be on the safe side?
Thanks for your help!!

You can run minirude or 3Rude.
I have the same ecu,with bosch 50's injectors.
Look in my signature ,i'm running the 3Rude and have no problems.
Before i ran the minirude also without issues.
You can tune your afr's with your rrfpr,.

I have no experience with the et charger,but the 3 Rude works fine,and holds the slip for a long time.
I use the new model rotax clutch washers on the 3 Rude ,so nu clutch issues for me.
The 3 rude gives massive power ,i'm very happy with the charger.
Next mod ,i'm gonna do is raising the rev limiter to 8850 rpm, by V-tech.

I don't have a boostmeter,but it should be around 17- 18 psi.
The intake manifold shouldn't give any problems,others have done this before without to much problems.
But it's plastic so you never know!

A 2rude would fit the bill with the 8600 ecu & 50's and easier on the clutch... 14.5+ psi @ 8500 rpm.
I'm seeing 13.9 - 14psi & 8260rpm with my rotax 8300 stock class ecu.
