I don't know the compression rating of any toy car engine BUT........

You won't want to hear this but I'd really consider getting a later engine as the solo are very scarce, not only the people using them but parts.

I know this won't help but it's meant with the best intentions.

yeah I no the engines realy old just haveing a potch about at the mo to see if I can get it to run the whole car has only cost me £100 to build so not realy looking to spend mega amounts of cash on it at the moment but thaks for the info

ratio

most of these little motors are about 8:1 ratio. strokers are closer to 10.5:1.

i know a new 26cc cy 2 bolt has about 80 psi compression on a tester.

 

[motorman]

14:1 is common, higher in some of your more highly modified engines from say, obr or someone that does custom work for you.

the stock zenoah g230rc is listed at 8.8:1 compression. couldnt tell you on the solo, no experience with them.

i have to agree with mike though, if and when you need to put some money into that motor it would be best to go with a zenoah or cy, just from a parts availability standpoint.

Thanks for youe help I tested the compression yesterday and Im getting around 60psi which is about 4 bar so theres a bit of waer there but it should still run.
The main reson Im playing about is it to get used to how tha bigger cars work and how much they are to repair plus have a bit of fun in the mean time. Im not a total newbie to rc just looking for a progression fromthe savage x that Ive spent way to much cash on
