Ok guys, I hate to ask this age old question but I have to! Ill be getting a new CRT in about 2 weeks and will be getting a new motor to drop in. I have about 5 other RC's so Im not a newb but I just cant seem to search out what I want. Im really only looking at high dollar motors because I want to do it right this time do the high end .21's do the job in a truggy? Im talking V-spec, P5, ws7. And is it worth the extra loot to get a rossi 28 or RB 28? Everything I hear about all these motors is great so I have no doubt that any one would be a good choice, jsut thought I could get some input from the masters out there. My fear of buying a 21 is Im not going to have enough power and a rossi 28 is just going to be balistic and un-controlable.

Thanks in advance!

PS, what about a modded versio of either size? Pros and cons of that?

I got this one. Get the 28 in the Rossi, Top, or Rex. Go with the nonpull version, I think roto and pull are B.S. Use a starter box, they are almost foolproof. Nothing worse than being stuck cuz of a dead battery or having to fix a broken string (don't tampons have strings?) or have the one way bearing go south. I hear people say that it frees up some h.p. too, which makes sense cuz there isnt the additinal load of a one way bearing for the crank to contend with. Plus the advantage of a lower center of gravity, the motor is closer to the chassis in the nonpull version. O.K. getting back to your question. Running a .28 vs. a .21, hmmm. Rick from R.B. mods is porting mine as we speak (Novarossi n528xr $412.00 Delivered to my door hotrodded in just 1 week) from what I hear these motors are truly unruly. U.M.T. and Truggy classes afford us the use of bigger motors than the sanctioned buggy classes, up to a .28. If the big dogs are running modded 28's, why would you consider running anything less? Never such a thing as too much power, thats what the trigger finger is for, learn to use the power, much as "Luke" learned to use the "Force." Call Rick from R.B. mods, 1-479-200-0286. Tell him Ekber sent you. May the Force be with you.

Well if I go the modded route Ill go all out with this, http://www.ebmods.com/pages/engines/...8_modified.htm. I dont really want to spend that much that is why I was thinking about getting a nice vspec or maybe even a modded p5. What is the main difference in a truggy gonna be between a 21 and 28? torque? I think with a high dollar 21 and a lowend pipe like a jp-1 Ill have more then enough already. Do you really think I wont be able to keep up with the modded 28's?

the engine you choose is gonna depend on you,youre driving style.and thensize of youre track. if you run a small to medium size track then a stock or modded p5 with a low to med torque pipe will be plenty. if you run on a med to large track then the options open up. you can try a modded p5 with a jp2 high torque pipe or you can jump to a rossi 421b 8 port engine wich is what i just bought for large tracks and try a low torque pipe so you will gain low end grunt and still have top end speed due to the 8 port sleeve. now if fuel milage isnt a concern then a rossi 28 is a good choice for med to large tracks but i would run a jp2 pipe with a 15 tooth clucth bell and a smaller carb restricter to smooth the power curve uot cause that mill is brutle fast almost to fast and it sucks down fuel like no other im talken 5-6min. this is just my opinion my choice would be a 421b for the tracks i run on and cause it will get good fuel run times and is blistering fast and very dependable and only 329.00 at amainhobbies.com. my second choice would be a hot mod p5 and then the rex 28. all 3 mills are great mills and you wont go wrong with any but some may suit better for some tracks than others so it really boils down to you and youre track size. good luck.

If you plan on hardcore racing, are on a budget and one motor is going to have to suit all your needs, I would say go big, there is no replacement for displacement. You can always "cork" a bigger motor to accomodate smaller tracks, but there is only so much you can do to a smaller motor to get it to run with the big dogs on a bigger track. I do agree with Roscoe, it all depends on your track, might I add budget. If you plan on racing at one track most of the time, then get a motor suited to that place. All the motors mentioned are great motors Don't buy those $100 motors!! It's worth scraping up the extra cash and shelling out for the high end motor once, as opposed to buying a cheaper motor often. From my limited personal experience, I have learned many things, and one of those is that you get what you pay for....

ALRIGHT nitrosport you win damn it!!! LOL. i will agree you can CORK a big 28 to run smaller tracks and the rossi mills do put out alot of low down grunt. but with those bigger mills at my track the guys that run them are struggling to make a 6 min. race run with a 150cc. tank. dont get me wrong i was tickling the idea of droping a 28 rex in my crt but no way if the run times are that low. so thats why why i oped for the 421b 8 port ive seen them run in alot of lsp trucks and they rip. until next time VADER!!!![:'(][&o]

Hoorah, I finally won something!! Wish I could say the same for track days!

The smoothest running, best idling quickest on the pipe .28 size engine I have ever run is the RB Concepts TM928. This engine is a Novarossi .28 that has been massaged to 7 ports plus two exhaust ports. It's fuel milage is greatly improved over the Nova version and you can hear the difference in the way the engine sounds. I have two Nova rossi .28s and they are for sale. I also run the RB Concepts WS7 X3 and it is even more of a gem but I run that in my Jammin buggy. I like the idea of having a .28 turning the bigger wheels and tires on the CRT. This engine cost about $340 and is worth every penny.

I went with the JP P5 mod for my CRT with one reason, Fuel milage. I am still waiting for my truck and engine to arrive. But I figure I could have one, may be 2 less pit stops in a 45 minutes main. Or else I can always go to the 28 later.

Anyone know the part number for the CRT wheels?

Thanks

This may sound a bit overboard, but I've got a P5 that I use for loose tracks and club races, a Hott Mods 528 for big races, and a second stock 528 for, well, just to have around

IMHO, if you're going to have just one engine, you should take a good look at what other local racers are running and make your decision based on that. Not everyone needs a .28 to win - look at Jammin team driver Chad Bradley. He ran an OS V-Spec (.21) to win the RC Pro finals at Sun Valley which had a tight infield and a 220' straightaway.

You cant go wrong with a JP P5, I reccomend the RB Concepts TM 928, (this is a .28 engine by the way) because is gets .21 size fuel mileage. I feel that the bigger parts will hold up better over a long race season, turning bigger tires than a buggy and lugging around more weight.

man you guys have me all kind of confused now! just kidding, thanks for all the great info. I think Im leaning towards a .21 of some sort, reason being is there are 2 tracks I race at, one a smaller for techy track with about a 90' straight and then the other that has about a 150' back strech but a pretty techy infield as well. So what do you all think about a EBmods P5. 349 and it sure does haul. What kinda clutchs are you guys running with these hardcore motors, I was thinking a werks slider type might be best.

So know one here runs a vspec?

A forum buddy yof mine from Austria runs a Vspec in his LS Por-R. he had it in his XRAY buggy and likes it in his truggy. He uses it with a Mielke 2011 pipe. For a .21, the VSpec has a lot of torque.

personally i would say stick with a high end .21..Currently I have the Rex P5(Stock) but I don't get my CRT until Jan 28th but I do plan on getting the P5 modded with a JP-1 pipe(small track very hard pack alil loose gravel on top)

Yeah I think Im gonna go with a .21. I think either a vspec or p5. I know some of the rb motors are great but I seen a more then enough people at my truck go nust over them things. they seem to be very touchy to both tuning and clutch. So does anyone run a slider clutch on their CRT?

I race my CRT on a medium-sized technical track and the standard P5 is more than enough. There simply is not enough space for more motor. Besides, the larger-displacement engines can be fuel-hogs!

Yeah that is what I was thinking. Hey Jextel, you race at the hut? I was up there a few times this past year, hopefully more this year. I racea hrosham alot also, only 5 min from my house.

Joech, the part number for the CRT wheels is 86104 and 86105. One is for the white wheels, and one is for the yellow (I can't remember which is which offhand). Hope this helps you.
