The TM.18 in my Revo is fast,,I dont get "Pulled" by any other "Production MT" on the track period,Truggies have me I admit,My truck comes off the track at 280-290 I have it tuned that way to get every ounce of power out of it,People always ask what engine is in the truck,they cant beleive just a stock TM.18 but thats what it is.Ive thought about a TZ but the TM is great.I could only imagine bolting one of these .30`s in a Revo or Truggy looks like lap times are going to get faster everywhere
