Supercharging in 2018-19; best option?
#12
Yeah that's the one thing I've seen with the Novi is it seems to have a lower power potential/boost threshold as advertised. I rarely see cars making over 400whp with these and rarely over 12-13 psi. Any idea why that is? Is 450 an unreasonable aspiration on just pump 93 with a 1200? I'd rather not toss in water/meth to something I'm trying to keep simple and reliable. I'll just lower my power expectations I suppose. I just figured a 3.2-3.4" pulley would yield me the results I was looking for over the standard 4" pulley supplied as their "Stage 2" option. The 3.2-3.4" pulleys are advertised to produce 15.5-16 psi on an ap1 respectively.
In the LHT SoS video the black AP2 was (supposedly) using the 3.4" pulley and made 13.7 lbs which yielded 402/256 on a skunk2 header/tp/stock exhaust w/ UK mod. I'm sure belt tension accounts for some power/psi variations but is it not possible to get a consistent 450 whp out of pump gas on this setup? I figured I'm gonna be maxing this kit/headunit out right off the cuff. Is there a particular reason why it's not recommended by SoS to exceed 9-10 psi on 91-93 pump? I read about the heat inefficiencies of the blower you mentioned, would the higher IATs/boost levels lead me to be more prone to detonation? Not trying to sound naïve here, it just seems like the KW kit can make a pretty decent range of power very easily where it seems the top comfortable output for the SoS operating threshold is around 400whp. Also it's not advisable to go smaller than a 3.2" pulley on an AP1, so I'd imagine to produce any more boost I'd need a larger diameter crank pulley? Problem is it seems that in order to spin the blower enough to make 16+ psi I'd be crossing into a danger threshold, no? I've just seen users here get higher numbers/boost than advertised by SoS for pulley combinations etc.
I appreciate your input!

Its not in SOS best interest as a liable business to recommend running boost pressures on their kits that fall outside of their comfort zone. That doesn't mean it isn't done regularly with success.

Look into the TTS C3892 if you want a rotrex. I would do the TTS bracket system but fabricate your own charge piping and intercooler system. The kit is far more reliable than the KW kit.
next in line is the SOS n1200, then the IMT. I'd like to see a TVS 1900 option personally.

You can attenuate the noise of the Paxton blower. I've had the SOS kit for a number of years running 14psi with Hondata KPro set to limit at 8,500 rpm. Using a Comptech Air Box and some custom asymmetric foam baffling the sound is reduced, the pitch is reduced and the "bucket of bolts" image is nearly eliminated. Folks know that there is something different about your car but it's not nearly as pronounced.
PS - I think that decorative carbon fiber is childish. So, I painted all of the CF stuff in NFR.

Rotrex wont touch SOS...Hmmm...Junky...did you forget about mine? I'm not quite at 585whp but pretty close at 551whp on E85 (measured at E65 at the time of this dyno) and only at 17-18psi and not overspun.

Still didn't touch the Novi, with over 600whp on the Novi 1500
