The Vspec is a perfect buggy/truggy engine. It has plenty of power, great on gas, and super reliable. This past Sunday my two friends and I were at Wolcott Offroad track running our truggies. One had the Vspec Speed in his Kyosho while the other had the standard Vspec in the Losi 8. You definitely can't go wrong with OS engines.

the vspec has awesome bottom end power. it makes power from 3,000-40,000rpm which is earlier then alot of other engines. most start at around 4,500rpm.

Its a 3 port with great power. perfect match for a truggy IMO

i am running a v spec in my mugen truggy and love it, i just started tuning it last weekend and i was getting 8 to 9 min a tank only running at 190 to 200,i left the os .28 at home and dont miss it one bit plus i was only getting about 5 min with the .28
also the v spec is so easy to tune you basicly set it and forget it i made one adjustment all day, thats what i like

The V-spec has been a good motor for either application. I have a few modded V-specs out there that push a truggy around like it was a .28 and getting over 10 minutes of run time out of it. We have over 6 gallons on a couple and still going strong. Alot depends on the tune and fuel/oil used in terms of motor life is concerned. Most of the rossi and picco based motors I have done have lasted easily into the 10+ gallon range when taken good care of.
