"From 3500rpm, up, those 40mm would be holding you back."
All I can say is - it sure doesn't feel like it. The cam only really kicks in at 3200 rpm or so, but then it pulls hard up past 7000 rpm. Definitely a large improvement over the re-jetted SU's that were on it before. Is it possible I'm missing out on a whole lot og pep without some 45's or 48's? Very possible, but I'm not going to spend a bundle on some just to find out. I'm sort of done tinkering with the PV. Switching from 40's (I got the whole set up for $350 shipped on eBay) to 45/48's is one of those expensive incremental things that you get into past a certain point.
I had looked into putting on DCOE style injection bodies (my R-sport head isn't drilled for injectors, and a D-Jet manifold doesn't fit in a PV anyhow) but got sticker shocked, and decided the 40's worked good enough, didn't need to put fuel injection on it. And I get all my electronic fuel injection kicks on my 245 now anyhow.
I haven't weighed the 245, I need to find a scale somewhere and do it some time. But it is a late model 245. With ABS/Air bag-n-knee bolster/power this-n-thats. All in all about as heavy as a 245 ever got. I figure with me sitting it it's probably around 3300 - 3350 lbs? 14.09@97.57 mph was my best run, and it still wasn't quite running cleanly. I guess it probably doesn't quite calculate out to 250 whp, depending on the calculator you use. I'm going to pep the ignition up by replacing the bosch ignition controller with an MSD 6A box and see if that helps.
