Corker result Scalded!
Shame about the copper fittings problem...but even with that considered..sounds ace!

Thanks for the post Brett, makes it all worthwhile.

Fantastic results Trev
Having seen the Revos...I never once doubted they will work....
I wonder whats its like to invent such amazing stuff ??
I'm obviously very proud of the products I've invented/designed and pleased to be making so many people very happy with them but I'd like to be applying my inventiveness to other more important matters like health related issues and when I retire from nitrous, that's one of my intentions.
Did you worry it wouldnt work ?
I have a very handy ability to visualise my thoughts very clearly and also the ability to run my designs through a high degree of R&D work in my head, before I have to make anything physical. This means I have a good degree of confidence in them, before I start the expensive part of creating them.
I'm also lucky to have a very strong determination to achieve my goals, so even if I encounter an unexpected problem in the production process, I don't let anything stop me finding a solution.
Having said all that, there have been a couple of times that I've been close to having to right off HUGE sums of money on components that initially looked to be useless but I've always found a solution to avoid that so far.
When you have invented as many things as you have, cannot you say to yourself....well the last thing worked and the dozen before...so this one will... ??
I've certainly gained confidence over the past 35 years to that end but I've also experienced the 'near misses' that nearly cost me my business, so that tends to balance things out. I also have to keep in mind that there could be a first time I could fail, so I can't get too brash with it, especially when the cost could run to many 10s of £1,000.
As far as myself and a LOT of other people are concerned....if you said to me...here is a magic Nitrous box the size of a penny that will increase your power by 200%...I would buy it instantly....and thats a reputation that I envy
That's very nice of you to say so Brett and although my next great thing (after the Revo) is considerably bigger than a penny, my early expectations of the idea/design are great and I'm hoping for a substantial increase in the amount of power we achieve from a given amount of nitrous, which will result in a bottle of nitrous lasting MUCH longer. 
Even though I use your system..I look at a fair number of cars with "other" systems on them and I can SEE they are crap....the engineering is awful, they also dont understand even the basic principles...and even when you try and explain....they either dont want to know or dont listen....which is frustrating for me but must send you mad I would think....
It's been infuriating over the years, especially the jumped up 'experts' who may have spent a few years 'tinkering' with nitrous and then think that puts them in a position to question my 27 years of 24/7 dedication to the subject but I'm immune to their pathetic insults now and feel sorry for their poor mental state, because you'd have to be mentally ill to think like that.
Congratulations again on a fantastic result.....and thinks to himself....I wonder how long before I can run Revos on my Porsche
Thanks again Brett, your words of appreciation and encouragement are very gratifying.
All the best Brett

1st pass I took an educated stab at what setting to use.
Shows how well you've been educated then. 
I think we need to emphasise some of the following statement;
Now remembering my (single stage) set up can supply 600bhp of nitrous, using the Max extreme I limited the maximum power to just 150bhp.
I launched at 60bhp, held that power for 0.5 sec, then built to 150 bhp over the next 1.5 seconds. This gave the best 60ft I've had in a very long time! and a great start point to work from. For some reason I headed to the wall and backed off lots, but still pulled a 7.701 @ 163mph.
Shame about getting off line and having to back off, because that would have inevitably been a quick run and would have been a great step forward for the Revo performance.
Just out of interest, what 1/4 time did you run the last time you ran a 60ft that quick?
Again more emphasis needed. 
###The best part from my point of view is the 60bhp launch point, which you'll notice is 10% of the system's ability! Now getting 10% of a single stage 600bhp pulsed system is a) impossible, b) very "lumpy" if you can get it, c) will probably melt something, and d) will require a huge amount of retard... WHERE I HAD NONE!!!! that's right I started at NO retard and ramped in (a rather enthusiastic )6 over the next couple of seconds.###
Yep 6 was well more than you needed with a REAL progressive power delivery!!! 
2nd pass with hindsight my previous launch setting would have been a better bet
Hindsight would be handier if it were foresight.
This vibration loosened one of the copper pipe nitrous supply lines venting the nitrous under the bodywork and causing half the engine to receive huge amounts of fuel only and hence no power, so I had to back off and finish the pass on part throttle.
Maybe it was just a touch slack prior to the run, it's easy to miss one nut in the tightening process?
I did however run for a short time at full throttle and the half of the engine that was receiving the full 250bhp worked fine, so I'm happy with the fuelling aspect. It's also the most nitrous power I've been able to add to the bike up to this point (all be it to only 2 cylinders...) so I have another tentative tick in the box
A leak anywhere in the input side of the system 'should' affect the delivery to all outlets, although it may have affected one side worse than the other, so I wouldn't make too many assumptions about that just yet.
So, 2 passes, £300+ each pass,
It's only money - just think of the great experience you've had of sitting in the rain at the Pod once again!!!! 
all looking very good on the dual-revo wet system front, roll on the next meeting mid June!
With you all the way on that one Dave and could all supporters please pray for a sunny June.
|
Once again you've done everything you could to move the program forward and you have my sincere gratitude for that.
Best wishes for the next meeting.

Thank you - and you're most welcome
re the 60ft: I've run a 7.18 with a worse 60ft than that.
Looking at the 1/4 track time (330ft) it was heading for a low 7.2 with that power. So having the same setting, not backing off, and ramping in the extra power would have qualified me quite nicely this weekend.

That sounds a very respectable time for such a small dose of gas and on what would have been your FIRST run with the system working correctly.
I think that bodes well for your next meeting, weather permitting.

Unfortunately yet more rain washed away Dave's chances of progressing with the Revo program, as track time only allowed ONE qualifying run (which got out of shape) and one race run where a plug gave up, causing it to misfire all the way down the track. 
We now have to wait approx. THREE months before we get another chance.
Isn't it always the way!!!!

Hi Tez,
If you look back a page (and possibly earlier ones as well), you'll see that Cav has been gagging for the Revo (like so many others) since I first mentioned them, so sorry to say there's no credit to you on this one.
Regards

Hi Bob,
Everything is progressing nicely but slowly, mainly thanks to the terrible weather we've had, preventing those customers with Revos getting track time.
However we are in a position to offer the Revos to selected customers based on their intended use and location.
If you'd like to PM me your phone number I'd be happy to discuss this with you.
Regards

Thanks for that Lou, I'll do my best to avoid a beating then. 
Glad you made it back again.

Unfortunately bad weather and a poor track schedule screwed up Dave's efforts to prove conclusively (for those who aren't smart enough to appreciate the benefits without a world record to prove it), the benefits of the Revo system.
He did however prove CONCLUSIVELY to all involved in the project, that the Revo concept works EXACTLY as I predicted.
We could release the current units to the public now but we decided to hold back on general release until Dave runs a number that should impress the world. To this end I've taken delivery of Dave's bike and we're going to carry out some R&D on a dyno to optimise the settings and then freshen up the engine so it's ready for the start of next season, so that weather permitting he'll have the best start possible and hopefully that will lead to the best possible end.
Regards

Great news!!!!
We started tests on Dave's bike and found a VERY IMPORTANT problem that's adversely affected ALL this years performances.
Although Dave has only had good weather for a couple of meetings this year and only had a few full 1/4 passes, those have not produced the results we expected. For the last 1/2 of this year Dave has been assuming that the Revo system has been running too rich, causing the engine to missfire as the flow of nitrous was increased by the Revos.
He was lead to this assumption by the O2 sensor and plug readings.
At the start of this year he switched from a combined Schnitz progressive/ignition system to an MSD ignition (for the wide range of retard it offers), on the assumption that the spark strength would be as good if not better than the Schnitz.
Prior to the last couple of meetings I asked Dave if he was sure the ignition strength was OK and he assumed (due to the good name MSD have) that it would be.
I still had my doubts, which is why it was the first thing I checked once we got the bike up here.
The results of the test PROVE that the spark strength was NOT EVEN ADEQUATE for a strong n/a engines requirements!!! 
I can't begin to count the number of times I've said to different customers, that a weak spark produces the same symptoms as over rich mixture.
All year we've been trying to rectify a relatively minor mismatch between fuel and nitrous flow through the Revos (which I could NOT imagine was adequate to cause such a problem), when in fact the ENTIRE PROBLEM has been the ignition system producing an inadequate spark.
Why any MSD unit is producing such a weak spark we have yet to determine (Voltage to the unit is good) but we will find the cause and rectify it, so that Dave has a monster spark for the start of next season.
The lesson is NEVER ASSUME ANYTHING!!!!
We ASSUMED the MSD would do the job it was designed for and we ASSUMED that we'd have some problems to overcome with the Revos because it was a new concept.
We were WRONG on both counts!!!!
ROLL ON 2008.

good news (I was looking for one of them spark plug strenght testers other day )
Cant wait for the dyno Videos or the revos to go on sale i have an idea for next year :-)
Figers crossed hope all gose to plan with daves bike
