.27 or .18
 

Well i have a HPI nitro mt and was wonderingwhich engine to put in it. The .18 engine only has 1.9 horsepower and the .27 has 3.1 horsepower which is a lot. I think if i go with the Trinity Sirio .27 Racer Monster Horsepower 27XL which will probably get the truck to go 70 MPH but if i install the 2-speed transmission then it would go 90 or even 100. :D. But the other car i want to get is a scheumacer sst fussion which with the optional gears it can go 80+ which is great. An if you can't tell i an a speed freak always trying to get things to go the fastest and be the strongest at the same time. Or i would put a Rb concepts engine in the MT and with a RB innovations supercharger.

it would probabbly go 20-30mph faster with the .27 i'd get the .27! lots of torqe

pay attention to the rpms...not the hp

RE: .27 or .18
 

Qute "pay attention to the rpms...not the hp" well the .27 has 3.1 hp at 40,000 RMP. which is not bad.

I think the .27 may be way too much for the mt. I would think a truck that small would stay on its back from flipping. Do you think the drivetrain is designed to handle that kind of power??? I think the .18 will be a bit much but it will be fast and easier to handle, And not as many problems with the drivetrain!!!!!!

RE: .27 or .18
 

you can get .12 and .15 motors that go over 40k rpms, that would be your best choice.

You think so huh?

RE: .27 or .18
 

well that engine has a lot of torque and it is a oversized engine for the truck. It is like putting a 528 hemi in a honda accord.

RE: .27 or .18
 

do you know of any company that makes engine that have about 44,000 rpm's for a .12 engine?

Skip the supercharger. Do a search.
