Will do so any ideas on a good temp range like I have said I always tune for performance and feel not temp but my rule of thumb has always been 220-250 is this a good safe range to everyone especially on the p5 or should I look at Mark's 240-260 which is not far off I always figure me playing around and tuning I like usually 230ish cause once racing it seems to up that temp just a little.

Also your idle gap should be set with the venturi removed. When I use to measure the gap, I would find something along the lines of a sewing needle or pin and mic it (they are normally around .5 to .7mm) and go from there. My bet is you will find that it is severly rich on the bottom end and wont run or idle and possible lean on top. Generally speaking the nova HSN is about flush, or just in from flush. Its all an adjustment game. once you get it up and running, get it up to temp for a tank before you try to finish the tune. Let us know how you make out.

Maybe Im missing something - what chassis is this? Buggy or Truck? That makes a big difference with what pipe you need. IMO pipes make a BIG difference in performance, IF you know what your looking for and HOW to tune.

A 9886 works very well. It is what I have been running. It should all kinds of power out the corners.

Ok guys have a bit of a problem here hoping someone can lead me in right direction. I recently purchased a novarossi p5xlt because of all the hype I've read about them and it seemed perfect for my lhs track which is a great smaller sized tight track with decent jumps coming out of corners. That being said the p5 from what I've read is a monster out of the gate which is exactly what I need. I am running a ofna 086 pipe which seemed to be highly recommended for this engine and byrons 20% fuel and thus far the problem lays in out of corner power or off the line power. It's seems real doggie but once rpms get to mid range the thing screams and just puts a smile on my face every time it gets there. So is my pipe hurting the low end performance that much since it seems to be a shorter pipe? If not what can it be its hard to be competitive when I'm having to push it so hard in and out of corners to try and keep my speed up. Oh ya I swapped this engine for the xtm .28 pro which just had more than enough power to take the jumps out of corners. It's in a hyper 7/ 13 tooth bell so should be geared right I believe

Agree go up in nitro % at least 25
Call me crazy but i used some 25% and couldn't get the scream I did with 30%
Only reason I used it was because I was out of 30%
I'm sure i could have worked on the tune but it was just before the main and didn't have time

Also IMO - you cant compare a basher's .28 to a high quality racing .21. The 28 will have more power than most .21 engines.
Now that I see .28 - I'm going to assume you are running a truck. The truck is heavy, alot more meat to move. I ran the 8.0mm restrictor and I low end pipe. The 053 should be noticeably different if the engine is tuned correctly.
Running a P5 in truck really helped teach me how to drive as I had to run smooth lines in order to keep the speed up.

It maybe tune related, but running 30% will open up the tuning window quite a bit. It has substantially more power and if you are a little rich it will still move pretty good. Running 20% you will never realize the full potential of the engine even with a great tune. It will always feel sluggish compared to the guys running the right fuel.

I am right now sids with a complete tune issue after many videos I've seen this thing should put that .28 to shame. I also agree about nitro percent but I drove 45 minutes when I bought my fuel and they did not have any 25 byrons and I really like that fuel so I try to stick to that brand. So I bought the 20 but that being said usually it's performance through the whole power range you lose not just top or bottom. Highs only got to 50s today never got to play with cat will do so in a.m.
