What are the requirements for a "legal" ROAR engine? And also is that engine I purchased illegal

SqueedilySpooch

sry can't find the true specs to it but they have the same rpm range as a nova rossi and pumps out more than 1 hp i think its 1.6 not really sure and it uses a turbo glow plug and is racing legal

SqueedilySpooch

sry but looking at ur it has 5 ports rules state that u can only use 3 port for 1/10th sacale sry if u plan to race offically

infernoMP

How would they ever be able to tell the difference? The 3-port engine looks almost identical. Do they tear them apart and tech them at big races?

SqueedilySpooch

the got x-ray scanners lol




edit: SPELLED GOT WRONG[X(][X(]

infernoMP

shucks....guess if I wanted to be "legal" I could drop the 3 port sleeve in there......assuming the carburetor is the same

What ride height does everyone run their R40's at?

SqueedilySpooch

i made mine the lowest to see how it will improve my down force and handling its about 4-6mm off the ground

infernoMP

wow pretty low.....so that puts you at how much preload?.....I'm running box stock right now ( I havent even ran the car yet though). I think stock is 5mm on front and 3mm on rear..

SqueedilySpooch

3mm wow thats the thickness of ur alum chassi thats how close and the 4-6 thing well i jus measured with my fingures so its rough estimate

infernoMP

Well I'm talking about the preload itsself...I have 5mm of preload in the front....and 3mm in the rear....you should be able to check your ride height and your preload by using the handy little gauge they sent with the kit. Not the actual ride height.....I'm running around 7mm ride height*** in the front......and who knows what in the rear because I have yet to receive my engine to set the rear....

SqueedilySpooch

wow luky me i got my engine and when u have the chance next time show some pics with ur engine on with ur crappy digital camera

infernoMP

I would like to see yours as well.....with the body on......I got the Pontiac Trans Am body to replicate the car I used to have

fastcrash

you guy,s may notice that the brakes may sometimes stick on the r-40, if this occurs on your car, you will need to put an aditional clevis on the brake pushrod,take a look at my picks on the first page to see what i mean.

SqueedilySpooch

my brakes work fine but jus incase i'll put one in ok thanks for the tip

here is mine, how did you guys route the servo wires in your cars.

infernoMP

I routed mine in front of the gas tank...and through the receiver cover hole....I tied the excess wire up neatly where the transponder holder is....through one of the small holes with a wire tie. I'll snap a pic of it real quick.

infernoMP

Sorry I couldnt get my piece of crap digital cam to work tonight...here are some really low quality pics though. I'll take some more when I get a higher quality cam.

well, i thought i pretty much had figured out the cyntax clutch, but i am stumped. every time i run it, the clutch bell gets loose. have any of you guys used digital calipers to adjust your clutch? i don't want that hasle. is there a way to use a regular clutchbell and shoes?

infernoMP

I just finished putting my engine in. The only reason I can guess that your clutchbell would be loosening up is because the screw that threads into the end of the crank shaft is vibrating loose...

that screw loosened up, and mangled the small flanged bearing. but, i have never experienced that screw loosening up before, and the clutchbell would always get wobbly

infernoMP

It comes with shims. Shim the excess play outt've it. You only want 0.2mm-0.5mm of freeplay when the screw is tightened all the way down.

i toasted my flanged bearing.

R40Victim

I've only seen one bearing go bad in the clutch, and he's running a Sirio, 1.6 HP. I'm still running an HPI 12 rxs(1.35 HP). I still have the better laps times, but when his driving skills catch up to mine, he'll have a faster car... Not sure, but it seems a motor that powerful can tear things up if the tolerences are off. Like the guy said before, the shims are used to nearly eleminate play. Did you use thread lock? At 38k + rpms, it's no wonder something could rattle loose...

infernoMP

Time to break in my engine. Wish me luck... this sirio is screaming tight at TDC and the manual sucks for it. I'll probably be back later with questions regarding the centax clutch.
