Default OS Turbo TR

The manual says two turns out from closed. Has anyone tried this? Or is it a miss print?

Thanks guys.

Paul: 2 turns from closed is the default needle setting, you can start with 2 turns and lean it down when running in on the track. The TR 5 port turbo is a fast engine in small to med track. the engine like to run a little hotter to give the power, I am running mine at 130-135 deg. 7 races and the the engine still have very good compression.

PS: I think my OS TR Turbo is only has 3 ports and not 5.

Paul: No problem with the fish, to be honest I still prefer my sigma. The car is fast and handle well. As for OS the 3 port cpme with normal plug, you got to change the button to turbo type to used turbo plug, only the 5 port come with turbo button cos it is an outlaw engine.

This is what I got from my LHS guy, we tried to tune a TRP and had nothing good out of it, then the guy tuned the TRP and it was running brilliant. What he said is

HSN - 2 turns out
LSN - 2 turns in (I will ask again how to get 2 turns IN)
Middle needle - keel it flush and then turn it in up to 2 turns.

What I noticed is that the middle needle adjustments makes a lot of difference to the TRP's output. See how that works for you.

Well I'm in the Market for a New Motor ....again. Probably going with the TR. Let's see if it can hold up to the rookie torture test.Anyone blow their's up?Is there a differance between the Cranks in the Turbo 5 port and the Std. 3 port?I have leftover Turbo head button and a big Grey Cooling head Maybe I'll have a 3 port Turbo.
