With the 300x extras what would a 225 hp put out for hp?

[endabran]

I'm as curious as u lol u tell me were there's a good dyno guy in se Michigan and ill find out it feels like 250 to 270.I wwent from a 200 to this and the difference was drastic.

[baja200merk]

That's an efi motor not an opti

[Todd D]

It probably has a 225 dfi clamp bracket and the block from the opti was used also....... Was it ported to 300x specs or are the sleeves still factory 225? What's the compression? Who built it?

[endabran]

Yea forgot the optis are dfi this is epa nightmare efi dont think its ported

[endabran]

Should say i dunno cause I've never had it apart bought it as is, ill throw a gauge on it tomorrow

[Sleek Jr]

Yah I was wondering why you said it's thristy if it's an opti.. I thought optis were good on gas.. ?
