I found this dyno chart of a RIPP supercharged Wrangler that includes boost in the chart:Where did you get that from? that looks nothing like our curve.
Looking to see if we can get a clear chart up for you.I found this dyno chart of a RIPP supercharged Wrangler that includes boost in the chart:
I can't remember where I found it, and can't find the original source again now, but it was very clearly presented as a dyno chart of a RIPP supercharged wrangler.
The boost curve nearly perfectly matches a quadratic curve.
Since your website states that the optional high altitude pulley produces 9-11psi, I assume this chart is from a kit with that pulley (10 psi peak in the chart). Your standard kit is marketed as 8 psi, so I represented the standard kit's boost curve as a quadratic curve that peaks at 8 psi at redline.
If this does not accurately represent your kit's boost curve, I'd love to see what it really looks like.
BTW - here's Magnuson's chart that I pulled their boost curve data from:
That is totally understandable and respectable. In no way are we trying to hijack this thread. Just questioning the info that was posted about our product.Ripp let me pay my respect your system is awesome. It appears to me you guys have truly pioneered the way for all others. I am simply rolling with my gut here when i say for MY jeep I am leaning towards a twin screw. From my experience and seat of the pants knowledge, the twin screw doesn't have the lag that a turbo or centrifugal charger has.
Yes I made that claim that the SC produces minimal gains under 3K RPM (....the edelbrock chart you just posted starts at 4K....lol but that is just their crappy chart) The previous vehicle I had when going FI there were minimal power gains to be had under 3K so I mistakenly assumed that was typical of all SC, but that was a very different beast with 2 more cylinders and not applicable to this situation. I apparently I ruffled your feathers with that remark that was not my intention. I look forward to more information about these superchargers as I would love to put one on my wrangler.I'll own up to being the one that derailed the thread. I should have just posted the original Magnuson dyno chart with boost curve to make my point that the Magnuson makes significant boost at low RPMs (to counter the claim that it doesn't produce gains until around 3000 rpms). I was lazy and just posted the comparison chart because I had it pulled up in another browser window at the time.
No feathers ruffled here.The previous vehicle I had when going FI there were minimal power gains to be had under 3K so I mistakenly assumed that was typical of all SC
