Wicked 2.47L Supercharged Stroker Honda S2000 Dyno Pull youtube has a 1500 on it http://youtu.be/Td4MA5rgq64

 

Thanks for sharing

Wonder what psi he is pushing, that's going to tell a lot. The powerband is shifted down a good 1500rpm, which for a turbo car makes better sense then a SC one, due to the nature of how these set ups produce boost and their efficiency range. 300trq is strong for just 430whp, but not by a lot for the trouble and expense of building a 2.4 motor. 275/285trq is typical for stock at 430whp.

 

Not sure if you are disputing me, but the S-Trim is the 1200, the Sc is the 1220, the Sci is an Si with a trimmed impeller and flows more like the original S-trim.

 

urBan_dK: I am not disputing you, but just stating the truth... My source about the Novi 1200 = Paxton Si and the Novi 1220 = SCi is from Vortech Tech Support (Jamie) when I asked for the compressor maps. I asked for these when I was doing some research about upgrading from the 1220 to the 1200 (which I run now). If you looked at the posted compressor map link, then you can see that the S-Trim, SCi-Trim, and Si-Trim have different maps. Call them up and ask yourself for the truth rather than relying on some random thread on the Internet.

 

So what bearing if there is one, does this current discrepancy have towards the outcome of what was discussed about the 1200 vs 1500 efficiencies at a particular boost level? Does this change our thoughts? Or are we fixating on irrelevancies with the topic at hand?

 

Not a random thread, a quoted conversation from a Paxton engineer that was posted in a thread. Go read it yourself for the truth

The current Novi 1200 is equivalent to the Si. There was an older one equivalent to the S. Paxton updated the name but Vortech didn't.

So I guess the S versus T trim compressor map is a little outdated. The T trim at this point (Novi 1500) is a bit long in the tooth.

Again, the SC and SCi are the old and new versions of the 1220, the S and Si are the old and new versions of the 1200. We are basically saying the same thing. And if the compressor maps for the Si are better than the S trim, then it just pushes things more in favor of getting the updated 1200 rather than a 1500.

The 1220 shouldn't be part of this discussion as it is inferior to the 1200 (flows 100 CFM less). It is really an upgraded Novi 1000 replacement.

 

Just a fyi from what SOS and joey told me the n1200 will make more power throughout the powerband than a n1500 pound per pound until you spin the n1500 blower like he did with a 2.6" pulley. In his thread when he ran both blowers with a 3.0" the n1500 lost 30hp in the whole powerband.

Well there you go! As suspected. Thanks for that info.

The 1500 only produces 50 more cfm over the 1200 per paxton website, wich is not much, and this I assume is measured at max blower speed, so going off of that it would confirm the higher efficiency level of the 1200 since it operates at 52,000 and 22psi vs 55,000 26psi of the 1500. So I might only make 500whp with a 1200, instead of 550whp with the 1500. But it will be at lower boost/strain and heat and less parasitic drag on motor under the curve. I'm starting to think a maximized 1200 with a good Aftercooler set up will net very similar power curve and peak numbers as a maximized 1500 with an fmic, but the 1200 with AC is going to run more efficiently, with engine response and fuel mileage. I'm starting to lean to the 1200 the more I learn. Plus fitment is 100% bolt in. The 1500 will take more work and therefore more headaches to me.

 

I would not rule out the n1500 as it would still make the power and will bolt up just like a N1200 and the AC is just fine for that blower. Just go with a 3.5" thick HE and s vortech water tank a joey did. I'm going to be upgrading to a N2200 in a fee months with a fmic so I will keep you posted on this whole...is that blower to big thoey everyone has....stay tuned

Wow, not even going to bother with the NV2000 huh, just go strait to the 2200. Why not the 2500?

So is the NV 1500 housing larger then the 1200 or not? I keep getting different answers on this. Something is either different about the mounting plate config, or overall size is different and needs to be modified to fit the comptech Aftercooler?
