Did I ever tell you about my first use of our prototype progressive on my Bond Bug. Sorry if I'm repeating myself but for anyone who isn't aware of the story, here it is again;
I'd been using the Bug as a R&D and Demo car with a fixed hit of about 20 HP and all had been going well for a couple of years. The motor was a fresh build at the start of the project and for anyone who doesn't know the spec of the Bond Bug, it was fitted with a 750cc Reliant engine as standard but I'd fitted a latter 850cc version.
So once I'd finished the prototype controller I fitted it to the Bug and realised that it could easily take more power in the progressive mode, so I started fitting bigger and bigger jets.
The engine only makes about 24 HP NA and I ended up with 60 HP jets with the progressive delivery, which produced IMPRESSIVE results and all was running trouble free.
A few weeks after I'd got to that point in the R&D, a regular customer came along and we started talking about my new concept, which he immediately appreciated and wanted to buy one there and then.
I pointed out that I hadn't got one to sell him, as I'd only made a prototype but he insisted on buying that, so I removed it from the car for him.
Since I couldn't fit a replacement and I had other potential customers wanting demo runs, I decided to drop the jets down to just 40 HP, as I didn't think the motor could handle 60 in a fixed hit. When I went to perform my first demo on those jets, I also decided to get into a higher gear and higher rpm before activating the system, in order to reduce the pressure/load in the cylinders. Unfortunately despite the reduced jet sizes and the higher gear/rpm, the instant I activated the nitrous system the engine exploded.
On inspection I found that the head gasket had been blown clean out and because it was so instant no other damage had occurred.
This was unequivocal proof that delivering the nitrous in a progressive way, not only made the power more manageable but also made the engine more reliable, so it was a no brainer from then on.
Taking these results to the ULTIMATE conclusion, the REVO delivery MUST (and DOES) enable an engine to handle even more power, as there are NO peaks of pressure, as there is with a pulsed system.
Just a shame the the BIG guys in the USA are NOT smart enough to appreciate what the REVO offers.
