Perry, why not run twin bottles in the car.mgbv8 wrote:What was the net result Paul??gelmonkey wrote:Perry

You have the time to do this before the show you know![]()
You know you want too.

The engine certainly does run out of puff. 0-100 in 7 seconds and then another 3.6 seconds to gain 27mph when it was on song last year??
I would love to do this before the show, but I've had so much down time with engine breakage due to nitrous rtelated issues that I dont want to bog myself down again. I always moan at folk for doing more than one change to an engine and then not knowing why its not working. But I went and did it myself at the start of this year due to crap advice from an "expert"!! And most of my season has gone now. I've got Retro + USC and 1 RWYB in Sept.
At this moment I have just one thing to re tune, and thats the carb fuelling. Then I can adjust the nitrous fuelling back down to 250hp and see if I get a good pass. I also only have 3 bottles of nitrous for this weekend so its gonna be tight. If I can use 2 bottles for dialing in on Saturday I'll only have 3 passes in an 11lb bottle unless I start winding the pressure up to the 950-1000psi mark when its half empty. If I use about 2lbs per run the bottle is half empty after run 3. This is when the bottle pressure drops off hard during a run so it goes rich halfway down the track
Im sure pressure drop would be much less over the run.
I ran a twin 11lb set up last year and even played with a 3rd bottle for a 2 stage set up. My ignition couldnt take all that gas tho. Hopefully my new low compression forged piston engine build and megasuirt will be ready for some proper nitrous abuse.
