The most shitiest fuel i ever drived is Jero Glo (But that fuel got me into 1/8 nitro car driving. I bought a Inferno mp 7.5 sports and was sold seeing the car in full action even with that fuel, because i didn't know better)then i started up with Model teqnicues race and dynalago fuel and i quite liked it, after a couple of years our own local hobby store change fuel into Rapicon fuel, i ran 25% with 9 % nitro and i think it was ok, not better then or bader then MT, it did its job, after that i tried out some cars of some friends of mine, MFR and Byron and i was impressed over most of what they achieved,run times, speed etc...I mostly drive Nova or RB engines and have a big passion for fast nitro buggies. The Piranha fuel did'nt gave me a waaaa ipression the first time i tried in one of my Nova engines who actually is the most pissed of engine i hav ve beside my Toto Nero Team, but on the 3 tank the fuel started to really improve speed and power after 5 tanks all i have to tell to myself this is the best fueli have ever driven, no problems holding the tune (compared) to other brands even if norway is known to have a lot of low and high terrain, moisture always changing becuseof weather, i have to tell u this couse usually never have problems tuning engines. The Piranaha fuel is sick with that and when it comes to speed, even my Plus.21 4BTT started to act like a sick 7 ports beast. So please you tell me what it is with this fuel that is so good, since u were a litle negative to my"Statement" about this fuel yesterday. BTW do you know about pipes and headers to the Novarossi Bonito 7xlbs how does the 9886 pipe works with a 41021 header when it comes to speed? I am asking you couse i cant reach Huoston at the moment and this is rather importand

Perfect for allround use. All i wonder if the 9886 works with the 41021 header. I am
going to try a speed test with one of my cars. Up with some tooths from 15-18(19)
another clutch, venturi from 6.5-7.5. It could be fatal for the engine but i am willing to try it.

Best mileage of all engines at the race, all the bottom I could ask for, and a top speed that no other drivers could match - and thats with a 6 mm venturi. Buttersmooth powerband

As for Keep Off XL, same items except rear bearings are different.

The piston/sleeve/rod set from Toro Nero Team engine is very close to Bonito & Keep Off XL. The part numbers are 08567-T10 vs. 08567-T11 and upon inquiring to the folks at Novarossi in Italy, they stated the sleeves are slightly different but will work in either engine.

Hope this helps

I also have a 2045/198 combo that i use in my RB WS7 L2G and a S7 L2G. I have some racing engines that would be fun messing around with different pipes. So if you have any good ideas, here is the Racing engines i have: Novarossi Bonito 7XLBS, RB WS7 L2G, RB S7 L2G, Novarossi Pluss.21-4Btt, Novarossi Toro nero Team i actually owned 2 toro neros but a bastard stoled one of them, and then i have a team orion 3 port engine i bought used, so i don't know what type Team orion 3 p it is, probably from 2009. i Forgot to mention that i have 2 9901/41021 pipe combos and a 9886 pipe, So if you or other people have some good ideas about combos that is very good based on the engines, Pipes and headers i have, let me know Today i am going to try out on my Xray XB9'13 a 17T clutchbell in My Bonito 7xlbs where i normaly use a 15T, the stock one is 13 but the Bonito is to strong to use a 13t it will only do wheelies and spin all to much so i have to use a 15T the bottom is still very very strong but driveable and offcourse the speed has increased a lot , but anyway im going to test out a 17t to see how fast it goes, i could have tried out a 19t but then i have to drill out more space in the chassis that holds the engine mount. With the 15T i use normaly in my xray have a peak speed that holds 68 kph with the 9901/41021 combo ((I use a Skyrc Gps) with the BHP the Bonito holds im sure i can give fulll throttle from the start, but if it was a 19 i think i would have been very carefull with the throttle from the start. Yes it is fun to see how fast this nitro racing engines can be and the bottom who can be faster then a el powered offroad car.
