NITROUS OXIDE ( nos / n2o ) advice forum

In my last post (in the original thread), I said I wasn't expecting much from Cecil's ALL NEW & UNTESTED Pro Mod bike and his first runs indicated that I was right to think that way, as it was SECONDS off the pace.

HOWEVER, in JUST THREE RUNS he tuned the set up to not only be on the pace but allowed Ryan to get the bike within a HALF A TENTH off the TOP bike in that round with a 4.289 to a 4.236 in the FIRST ROUND of eliminations.

I'm just waiting to see what the outcome of the final (between Ryan & the TOP guy) is going to be but either way I couldn't be more pleased with the results so far and there's NO DOUBT he'll run MUCH QUICKER in future, just as he did with the Real Street bike & the Pro Street bikes.

Also of note, that 4.28 had a pretty slow 60 foot and 330ft time which is completely understandable from a team new to big tyre bikes or just a new bike fine tuning in general. She sure is making some power down the track with the WON nitrous system though. 6mph up on its opposition at 1/8th mile!!!!

Another point of interest (which must highlight the smoothness of the WON system) is that this bike uses a Haybusa motor (the opposition pretty much all use GS Suzuki based engines).

Hayabusa's have not been popular in big tyre racing as yet due to strength in the gearbox and crankshaft (something that the GS motors do well). Cecil is obviously taking advantage of the smooth pulsoids to keep the driveline in tact.

The smaller motor will be compensated for the high flowing downdraft style head that the Busa uses over the GS style engines though.

Just found these more comprehensive results (although the 2nd round times are still absent) and it seems Ryan improved to a 4.24, so a move in the right direction again;

Although the times were good for this round, the bar is still set by Ashley Owens with a 3.97 from last season. Hopefully HTP can smash that!

Sam

Don't forget that Ashley Owens record is now IRRELEVANT for the class as there are now weight limits which have made most bikes heavier and I believe there have been other changes made that have also resulted in slower times for the class as a whole.

Unless I'm sadly mistaken, ONLY ONE bike so far this year has run under 4.1 and I think that was a 4.09 so I believe the rule changes have certainly had a negative effect on times this season.

Regardless of that being the case, I've NO DOUBT that Cecil will ultimately DESTROY even last years record, just as he destroyed the Pro Street record last year.

Well it was AMAZING enough that Cecil & Ryan (BIG congratualtions to both by the way) managed to get on the numbers in UNDER SIX runs, if you assume (as would be reasonable to do so considering the results), that Cecil had got EVERYTHING SPOT ON.

HOWEVER, IT'S EVEN MORE AMAZING when you consider the following information, that I've recently had reported back to me from Cecil;

1) The bike was serious under geared - resulting in extreme wheel spin and tire shake - which is why the trie looks overly inflated in the pics above, when in fact it's because its grown to that shape due to wheel spin.

2) It was so under geared that it was on the limiter in top gear by the 330 foot mark (half way through the run)

3) The mixture on the first few runs was PIG RICH but by the last run it was closer, although still 'very safe'

4) He was only using SMALL nitrous jets, that were smaller than he's used in his Pro Street bikes

5) He was using an extremely low start power percentage to reduce the wheel spin etc.

6) He was using an excessively long build time for the same reason as the low start power and also to ensure the bike got down the track.

7) Timing settings were WELL SAFE, as you'd expect at such an early stage of the game.

So taking all the above in to account and this weekends results are INSANE!!!!

Can't wait for Motec to finish testing the REVO & interface unit we've sent them, which is about to be fitted to this bike, because even on a single Pulsoid system I'm CERTAIN the bike is going to run deep in to the 3s, so God knows what it will do once the REVO is fitted.

Anyone want to bet against a 3.7 pass????
