I've followed this also and optimistic the 375 is the engine HP. Looks like a reputable company in South Africa. From the other stuff you posted from RG the rwhp from their kit is 248 from 139. I know the 139rwhp is lower than whats been posted. I think I've seen 162rwhp-177rwhp on here.

95 octane was used for their kit plus they are using a piggyback to adjust the timing and fuel from an intank walbro pump upgrade /w an added exrenal fuel pump. Time will tell how well this works
Of course if this works then no telling how much boost drop we will see in US w/ 93 octane or where some only can get 91 octane like in Colo. So we might be right back at 5-6 psi w/ 91 octane unless you want to add octane booster to every tank.

139 is about 35 low stock so the stock dyno is bull
7 psi is possible in high octane and a liquid-air intercooler
Gaining even -half- the hp they claim with only 7 psi is even bigger bull at 370 rwhp from orignal post
Now 248 is more like a 75 gain from a -real- stock 250 pull which is a touch high for 7 psi but not impossible
It's still 30 or so less than 3500 bucks gets you buying a 350 over a 250 and you keep your warranty
Supercharging a 250 is just a loser from get go

Pole Position
What if they use a Lysholm screw supercharger as opposed to the roots one that everyone else used? Theoretically they should be able to run it on 5-7 psi and get some pretty good numbers

Did you guys even bother to check the time that they were running? it says 0-62 mph was done in 10.44 on a stock is250 and the s/c one ran a 7.46
We all know is250s are slow but not 10 sec slow on a 0-62 run. And even if that the tests were done at 6000 feet, you guys think thats an accurate run?
