how much???

 

Couple of questions for ya.
Looking in the book I see the stage 4 kit comes with heads and a 58mm throttle body.
Do the heads come with compression releases or did they take the compression release from your old heads and install them in the new heads?
What air cleaned did you use with the 58mm throttle body? All of the SE air cleaner kits in the book state they are for the stock 50mm throttle bodies.

 

Numbers look good. I got the SE 103 Stage 4 installed about a month ago. Plenty of usable TQ and HP. I have not had mine on the Dyno yet. I am hoping for results similar to yours. What did they recommend for break in? My Service Manager only told me to not get crazy and bring it back in 500 miles for oil change. I only got a few days on it because I had to return back to Afghanistan for my job. Can't wait to get home and get it broke in good. Ready to see what it can really do.

 

Congrats on a successful build .... !

 

Harley is gonna make a killing on them kits. Get some power and keep the warranty on a new bike. They are EPA legal and ought to come that way!

 

Also did stage iv but bought it as stage 4 so it could be linked to my warranty then bought race tuner and injectors instead of download also put burst ac on runs great! ( I know stage 4 or stage iv seems the same but one is covered other is not)

 

Whats the difference besides hi flow injectors?

 

SE has a 58mm backing plate for the Ventalator. That is what I used. The compression releases come with the heads.
