Went to a rolling road day with a local club. was out testing the nitrous the day befor and had it running sweet. I was running a 100bhp shot with 1 degree retard on the ignition with 200 nos jet and 70 fuel.
Any way did one run without nitrous on the rollers and was real happy with the results making 155.4bhp and 126 torque.
so the guy was going to do the run with the nitrous now so i changed the ecu mapped for the pre saved nitrous map. He asked me if there was anything he had to do to run the nitrous, so i said yes the nitrous will cut in at full throttle so can you bring revs up to at least 3500rpm and then full throttle so the nitrous will come in. he siad that will be fine.
anyway he jumped in the car and stuck his foot flat to the floor in 4th gear at 1000rpm so it injected 100hp of nitrous at a real low rpm and that is not good, the car started knocking n smoke and I have lost compression on number 3 cylinder i rekon its melted the rings as the crank is pressurising blowing the oil straight out the breather.
I said to the guy wtf was that you did, he said the nitrous come in real agresive. i said yes coz you hit WOT to early, he replied ohh i thought you said the nitrous will come in automatical at 3500rpm. It was a comunication error lol as the fans in the place where real load plus he had his ear defender on. so that lack of comunication has now cost me my engine.
anyway got a new engine the same day. and is ready to come out tomoz so be back on the road in no time
If any1 would like to now with the 100hp shot i made 186 torque at just under 2000rpm which is pretty
Hi SAM
Hard luck mate, I didnt sell you that Nitrous for that
At least you understand what happened ...i.e full load at zero revs plus Nitrous is not a good idea...
Its why Trev mentions this so much, to warn against it...
Dont you have a Maxx yet ???
It would have prevented it , with The Window switches (rev limit switches)
Its one of the reasons , I dont run mine on a dyno anymore....
Unless the Operator UNDERSTANDS Nitrous completely, this sort of thing often happens unfortunately
Good luck with the new engine....and get a Maxx... I am sure Trev will do you a deal on a recon unit if you ask him ...
All the best Brett
P.S. It would be interesting if you posted up the dyno chart...
