you mean "tune"

havent any complaints yet 10 out so far


talked to chris about the pipe , he comfirmed exactly what i thought it was gonna be . 9853ss built for mileage , minor loss of power , great for truggy

i will be using it next weekend

Hi Houston what way does the rod go on the crankshaft with the hole to the inside or the outside it is a r7 rod in a p5xl I don`t know why I put a new rod in it and it broke today on the lower bearing someone told me maybe it was in backwards thanks.Tim

yea "tune" was the word lol

the hole goes towards the crank , be careful with those wrist pin clips

plus 4 team engines are gone for now , fms engines available next week , lmk

hi monty! very happy with the p5xs you did for me THIS MOTOR ROCKS 3/4 of a gallon so far running 200 degrees taking it easy and i was so happy running grp tuned motors in my truggy. but never again not even close in power and tune,cant wait untill she,s broken in . the engine heater makes it so much easier to break in also .sure glad i didnt buy a 28 would never need it ! i am sending you my new p5xlt for the houston tune forsure thanks again monty. you are the man and your information is priceless

great to hear jerry , i truly do appreciate your guys' feedback , that to me is what makes it worthwhile

hey monty is the n21r engine decent for a buggy with a decent size track . does it have decent rpm thanks

its not too bad , i can improve them a little

throw a good crank in them and they are comparable to many high end engines .

at the price they go for they are worth every penny for sure

you have pm

Yes he can and does great work. Montys engines run super smooth. By the way Monty the plus4c is really coming alive. I need to get more fuel though the filled crank plus4c with Alabama coming up in alittle over a month.

Thank you Monty for all the work you put into my P5XL!

This motor is perfect! Amazing useable power and plenty of it. Runs like a champ and the customer service is top notch!

I cant wait to hear about the clutch shoes.

How is the milage on the P5XLT is 10 min doable if not can a Monty Houston tune on it make it doable. What is the best pipe for this motor?

Monty is the man!! Purchasing my first nitro engine could of been better. the suport is umatched! helping is an undeerstatment finished breaking it in today runs perfect cant wait to race it!

You mean couldn't have been better ? Silly boy!! LOL


I just do what I can guys , like I said I really appreciate the feedback

I have seen them go 10 min yes , especially in a truck

I am thinking about this combo for an easy 10 min as long as you're smooth on the throttle .
P5xlt , 2084ss/41021 , 6.5mm restrictor , odo97t or 77t
