Hey guys, I have gotten one of the first Novarossi P5xlt from Neil about a month ago. Well, I finally have gotten over the 2 gallon mark and this motor is starting to loosen up. Here is what I run it in:

Mugen MBX6r
Novarossi 9886 Pipe and short header
Nove Medium Plug
Byron's 30%/9% Oil

This motor is absolutely phenominal. It has taken over 2 gallons to loosen up so engine life will probably be pretty darn good. The motor ran flawless all day yesterday and is one of the easiest motors to tune. I had heard some stories about Novas being really touchy and hard to tune. Not so at all!!! If you have both the LSN and HSN perfectly flush you can not miss a tune with a P5! After than it is a few hours in on the HSN and you can leave the LSN flush and it will run like a bat out of hell or if you are trying to squeeze the mileage out of it lean the LSN a few hours too and it is tuned perfectly!!!!!!! Speaking of mileage, with the combo I listed yes 10 minute+ run times is more than possible with the right tune, fuel, and glow plug. Out of a lot of buggies, me and a pro driver were the only ones able to go 10+ pit stops! I won my very long main by 4 secs. and I pitted 1 time less than a few guys and 2 times lees than most people!!!! The 4 second victory was do to pit strategy!

As for power. The whole modded engine idea really concerned me. I was affraid I would blow the tires off of it!!!! Not so at all. This Nova makes as much or more power than any OS Speed or anything else out there. The power is smooth and the top end is lethal on it!!!! zLike Neal said, he spends a ton of time dynoimg and running these engines in stock form to see where they fall short, then makes improvements on where it falls short. On the P5 the top is lacking a little and I can assure you it has been more than fixed!!!!It has a lot of torque and just a stab of the throttle and I am able to clear jumps much easier than my OS XZ-B before. As for the straight away I was pulling everybody by quite a bit. There was not one buggy or motor that could keep up or pass me on a straight away. It really shined when you were coming out of a tight turn and had a short little 30 to 40 feet straight to the next turn. The torque and power it makes and it accelerated like my ebuggy. This is where it was really handing people their lunches. I had no problem getting the power to the ground in the Mugen MBX6r. As we like to say in Knoxville, it straight hooks n' books!!!!! The great thing about the motor besides the run time, is after 45 minutes of pushing it as hard as I could, it came off at 208!!!! It was absolutely screaming too!!! Feels like a diesel on the low end, and a 572 cubic inch hemi with a 14-71 blower on the top end!

I want another one as a backup here pretty soon!!!!
