He hasn't done the mod yet, I'm still waiting for his feedback to compare against my experience with it, his IC makes it a bit more difficult to do it in a manner that gives the highest effect. But I can tell you from my experience so far it is worth every bit of effort.
Good work, I know exactly what you describe, it is doing more with less. Wait until you do the inlet manifold points, man that makes a difference. Along with the little mod I did to the airbox lid, blending from air filter into the Cobra Head, it is like everything is coming together.FIRST TEST DRIVEsecond nozzle at IC inlet pipe on a HPD IC). After some boost leaks and a faulty clamp and a family emergency we had our first drive .First thoughts and observations are very promising, there’s definitely an improvement when the injection starts and very noticeable. Used straight water, maybe a 50/50 mix would definitely give more pull. EGTS were around about the same in normal street/main roads.But there was a 5–10degree drop in EGTS on hill climbs. Did notice a drop in TPS %. This seems more evident in a double hill climb on my test track I drive when I carry out tests . Previously I would use 22% TPS and now getting up at 20% , does fill like l’m using less throttle also. Did back to back runs for confirmation. As for water consumption it’s not that much more, need more testing for accurate results. Will be posting more updates on this setup. Just a big thanks to Ross and Peter for the advice and knowledge.
Cool, that centre section is what mine looks like now with a radius. You have had it all along but after doing that small mod to mine I couldn't believe the change in driveability. Funny thing was (and I may have mentioned it in another thread) I did the same thing to ram tubes on the various Weber's I used when I was racing, had completely forgotten about it until reminded by OldMav.More with less is exactly what came to mind, will be doing manifold points at a later time. Just want to complete this trial before I move on. Helping Theo install his snow performance system in the coming days.I think a #2 in inlet might give a bigger hit when injecting start point is activated . I’m using a snow #1 60ml/min in inlet and DO 4 at TB progressive setup start at 7.5 -18 all out. I’ve got a HPD air box lid, with BMC , currently using K&N filter.
The criterion is set by tank size and distances travelled, it is no secret that bigger the nozzles the better the result, only limit is tank sizing, I would love a 20-30L tank but still finding it challenging to achieve.I purchased a second hand air box to modify but had a stuffed lid , so I liked the look of the HPD air box lid mainly for its polished aluminium look. Very expensive but did suit the BMC extremely well, nice fit for the k&n also. I’m confident a Snow or CM #2 would work very well in IC inlet. Every little bit helps.
Yes, those are the thing’s I check all the time as I mostly drive my truck once or twice a week these days. Check before start up and cool down and look at fluid level in tank also. All goodKeep your eyes on your catch can if you have one, and also on your engine oil dipstick. I found with constant use that you can see signs of condensation in the engine. I have adjusted my system to avoid this.
