I recently purchased your won pulsoid solenoids for my ex top gas 1500 gs Suzuki...123 auto...150 hp jets...30/32...
Pleased to have you get back to us with some results and for tuning assistance.
can you post some pics of your installation and the bike itself in action please?Started off at a 40% start..80% finish...all in 4 seconds....13* timing out...8 psi fuel..(C123octane)
Ideally you want a progressive means to retard the timing, to match the progressive nitrous delivery.First pass..8:30ish...track not sticky..tire breaking and rolling...two promods wiped out at the top end of the track located in Toronto Motosports part..Cayuga
Shame about the Pro Mod bikes, hope they both survived OK.Second pass..7.99@168 was set at 90% and 3 seconds to in...timing down to 11*...fuel pressure@ 7psi...plugs and wego good
Third pass 7:76@ 158mph..only change fuel pressure to 6 1/2 psi....Traction was excellent as it was Sunday and weather was heating up the track.
Pretty good progress for one day.I would like your opinion on the plugs and my wego readings to verify my own opinion. I use the regular plugs to dial in my stripe and fuel colour then changed to the double electrode style.
NEVER USE ANY plug that has more than ONE electrode and if you can only get single electrode plugs with ground straps that cover the centre electrode, cut them back to expose them as described in my book;http://www.noswizard.com/nitrous-ancill ... -book.htmlFYI multiple electrodes are JUST for longevity on street vehicles between servicing and the last thing you want in a nitrous motor, is more metal that can melt than you need in the chamber.I have never seen the plugs look this good before as I always seem to run better when they look lean...even though the wege o2 readings were dipping into the 10's and ll area. Now the reading seem to be more consistent..I did install a holley blue with a regulator as before it was just the 6 psi nitrous pump. Now fuel pressure way nicer to adjust with:)
OK with all that.Pulsoids Rock:)
Glad you like them. I couldn't get the wego readings downloaded to email...not that computer literate..lol
The readings didn't have the high lean spikes like with the previous solenoids which did make good power as well at 100 hp - best was 7:62@168mph
Being rid of the spike is certainly a benefit but not clear on what you're saying with the rest of that statement, please elaborate???First run average was around 12.6-13.2 average...regular plugs...8psi fuel
Second run average was around 13-13.5 ..regular plugs...7 psi fuel
Third run was average was 13.2-14.. Dual electrode plugs
12.6 would be my target and once I had everything else consistent, I'd do a fuel pressure swing to see the effect on the times on both sides of that.The o2 readings are always hard to define the areas as no rpm is hooked up , no race pack, just basic progressive controller..top gas...and wego and checking plugs , find it is better to look at the average. We have a cut off of 7:50 sec for this class and we want to run safely around the bump. No one else runs Nos in the bike PBSS NHRA division we are in. The others never know how fast we are going to run for qualifying...usually one of the fastest in the field except this weekend when we were just tuning. Now there is 3 other bikes running in the 7's... all NA
Just looking for another opinion to run safe on our budget. Do you think I am tuning properly? What else should I be looking at?
What brand and grade/number of plugs are you using?I do appreciate any help and direction
I'm more than happy to help anyone who wants to learn, so feel free to keep asking for any advice you may need in future.Oh I might mention that Paul Gast... well known bike builder ..good guy. was down at our event and qualified 3rd with their NA bike..
Interesting to discover that Paul races in Canada and I look forward to assisting you to BEAT HIM. we were fourth at 7:99 as we were tuning and no traction. A fellow racer asked when we were going to turn to nitrous on with our 8:30 1st run. On the second when it was breaking traction at 7:99 he changed his attitude and said how fast the bike would be if we would have had some traction:) which would now be more tuneable for track conditions
He'll be in a state of shock before long.
