Monty the P5 you did for me is running perfect. The torque is crazy, but its smooth everywhere, hard to explain. IMHO its the perfect race engine for a truggy.

i love the p5xlt for truggy

.21r limited...safe to take a shim out on 20%?

yes sir , no prob , take out the copper shim but NOT an aluminum

Merry Christmas and Happy New Year! Thanks for all the help

I have a pipe/header question.

RC8B, Plus 21 FMS motor, what pipe/header? I am not racing, just running around my yard and a large open lot.

Thanks,

Scott

if you arent racing then it really doesnt matter does it?

for awesome performance i recommend 9853ss/41021

are you trying to achieve anything in particular while you are bashing? major top speed , exrtra torque , etc. etc.

Really just all around good performance, Don't want to sacrafice bottom end/torque for top speed...If i want to go fast I pull out an on road car!

I have another FMS in an SC8 (bought it used with a pipe/header) and it has the 9853/41020 (might be a 21, can;t remember), and it runs well. What about a 9901? What difference would that make?

Thanks for the quick reply!

Scott

9901ss not the best pipe for fms

9853ss or 2084ss

lmk what you need

Shooting you a PM.

Scott

I can promise you 1st hand the 9901 sucks on an FMS.
