Dynamite .21XPE V. Alpha Red Head
 

Well i just picked me up a XPE and word it its just a red head alpha with a diffrent name and color head. I looked into it a bit and the blocks look the same, along with alot of other stuff. What you guys think also im ganna try out a GRP 2053 pipe. How you think it will work and whats the best pipe for these in the jammin jp line? I know alpha and dynamite have pipes but i want a jp pipe considering they work with alot of engines that i run. THANKS for all your input.

It is a rebadged Alpha engine so it will run good with any 0801 pipe. Not sure on the JP pipes.

Ok thanks Rad.

i have a red head alpha and works ok with a jp3 and jp4 i like the jp3 but i am using the a plus 8801 from alpha screams not so good for runtimes tho

Dynamite Xpe is the same as the Z852 green head. They say there is some slight difference but I haven't seen any. I sell Alpha motors and my son is sponsored by Dynamite and runs the Xpe. Never tried a 2053, we have ran 0801 A+, 2081 Alpha, 2072 Go and those all work well.

Ok thanks Rex. I like the Dynamite engine line there tough and reliable for the price. Not saying others are worse but im pleased with it. Im ganna try the 2053 and if it dont seem to do much im ganna go jp3 maybe jp1 lol

ive tried a 2053 and good luck getting any bottom end power out of it but it will scream about 3/4 down the straight lol. JP3 will suck, run time will be around 6 min. JP1 maybe, the 2013 or 0801 pipe are the only ones i would run. also i advice going to a 15T CB on the HB, it will be a whole other animal.

also you can get this 0801 (its the same as the Alpha 0801 but cheaper):http://www.amainhobbies.com/product_...EMCA-0801-Pipe

Thanks for all the help so far man! I wanted to go Alpha combo but i ran jbrl rnd 6 and my engine ran like CRAP the whole day so after my mom seen hoe bad i did she bought the xpe for me without knowing she did. LOL thanks mom it takes alot off my shoulders foa while atleast.:D Jus waitin ten to see when a servo deal comes so i can actually be set for good i need a steering and thats it now:lol:, but im ganna give that 2053 a shot wont gurt to try it out and see what it will do.

i forgot i tried an 2053, but good luck getting any bottom end power out of it but it will scream about 3/4 down the straight with the 2053 :lol:

0801 is the ticket, but from what I have seen the JP-1, JP-2, or JP3 all work well, with the benifits that each offer.. The biggest draw back of these pipes over the 801 is fuel mileage.. The 801 is far superior in that category..

Ok thanks everyone for pointing me in the right direction for a pipe im ganna go 0801.

in what tempeture should I drive this motor??

Don't be afraid to get it hot. I've run my XPE for about 2 1/2 - 3 gallons now and it's a bullet. My engine usually temps in the 260 range (O.S. P4 Plug), sometimes hotter. I usually don't use a temp gun anyway. If it's smoking well, coming back to idle ok, and clearing out quick when you step on it... then it's right. No temp gun required. :nod:

if its like the Alphas they run at around 260-280, when Alphas are new youll see temps around 280-300... i never check the temp on these engines, it will mess with you to much, the only time i worry about temp is if its over 300.

thanks guys!:)

I just did the break in with a GRP 2053, do you think I need to buy a new tuned pipe or stay with that one

Doing the break in with the 2053 is ok. I would still definitely recommend looking into the Alpha 0801 pipe regardless. I also ran mine with a Reckward 2041 pipe with very good luck as well. Either one of those will work awesome.

get the 0801 pipe, the 2053 has NO bottom... also do NOT run a OS P4 if your not a good tuner, the tuning window is extremely small, it does run better with P4s but its harder to tune. P3 is the most common and easiest to tune, also when its under 75 degrees out the P4 sucks.

and dont you recomend an jp tuned pipe?? witch one??

not for the Alpha engines, the JP pipes i only like on my JPX or O'donnell SS engine but run time is effected. on the Alpha or 21xpe, i wouldnt run any other pipe other than the 0801, ive tried alot of different pipes and alway put the 0801 pipe back on.

you can also get this pipe: http://www.amainhobbies.com/product_...EMCA-0801-Pipe
its a little cheaper and it the same exact pipe pretty much.

what you think about the 21xpe in general?? is a good engine? a cheap engine? or only one more engine???

The .21 XPE is no slouch of an engine. It is basically an Alpha Z852 with some minor changes (nothing that would really show performance wise). They're VERY tight engines from the start that require a rather lengthy break in period (easily a gallon), but they do last. Just don't go beating on it right away, it won't like that. I personally run P4s in mine, but I've been doing nitro long enough to tune stuff with my ears to know when it's right.

I've run my engine up against all the major brands. Just this past weekend against some of the NorthEast's fastest guys at the NorthEast Super Series, I TQed Pro Buggy and finished 2nd with my XPE. The track had a lot of high speed parts which this mill just loved.

It's a fantastic engine for the money that will run with some of the best stuff available. :nod:

nice to hear that!!!:nod:

One of the Losi guys here runs the XPE and that thing is NO slouch!!! Just like them all the wrong gearing and wrong clutch can make or break em.

What's the consensus on Dyn plugs? I just won a 6 pk of #5 and plan to use em in my Alpha mills this w/end at RCPro. I know, P4/P3 and or OD 97 are the popular choice, no need to tell me that over.

just got mine completly broke in on my 2053 i liked it alot not alot of bottom though but it will do the job.

Xray if youve got a 2035 laying around run it. Its real close to the 801 little better run time. Not alot of noise.

I run the #4 and think they are very good. They remind me of an MC59. #5 should be really close.

IMO i would go with the Red Head Alpha which is 30 bucks cheaper ;) almost the same exact thing. i know Alphas take close to two gallons to break in fully. when breaking them in, make sure to use a heat gun and get it up to about 180-200 before even crank it. idle 6-8 tanks at around 190-200 degrees and youll be good.

BUT imo the green head Alpha is better for buggy, and its still 20 bucks cheaper than the Dynamite engine...

On my Dynamite break in i got a lil over a half of a gal on the exp and with plug out i sitill have a little resistance, so im not 100% past break in but with plug in its got a butt load of resistance but i dont need a heat gun to crank it now. I just raced it friday with 2053 and loved it. I ended up actually winning and coming off a 10 min race at 207, it had alot of power and the pipe did good, im sure another pipe will do better but i got 7+ mins on a tank still running really fat considering once i get about another 3/4 gallon through it i will see what it does at about 240. Not ganna go 250 which is what alot of people say run it at but im confadent that i found my engine im ganna stick with and thats DYNAMITE! Alpha also very nice i might try it next.

i can tell you right now if you run it rich you will break a rod alot quicker, running rich wont make your engine last longer, it will shorten the life of the engine just like it would running it lean, dont be scared to get it hot, i dont use a temp gun for that purpose, i temped mine this weekend and i was coming off at 270-275 and it was tuned perfect. but like i said running it rich is bad for it too! :nod:

im not purposly running it rich im still in break in process. Trust me once i find that tune i like its stayin and the tune i had for the track i ran was perfect lol it was a lil track so it did perfect. Once i get out to my lhs im tunning it in to where it needs to run for a big and fast track. Im just trying to find longevity to, i would much rather pay 30 for a rod then 100 for a whole p/s/r kit lol.

is the xpe enough to push a truggy around:confused:

Supposedly this engine is comparable to the Alpha Z, Green Monster. That being said, I am running the Z in my D8T and am very happy :)

its almost identical to the F850.... and to answer the truggy question, IMO no, the Z works pretty good in truggy but the red head Alpha i have to say no, its to smooth... also i would just get a Orange head Alpha which is cheaper...

talked to the owner today and he said he is about to have them back in stock :nod:

I run the Alpha S852 (orange) in my truggy and the Z852 in my buggy. My son is sponsored by Dynamite and runs the Dynamite Xpe in his truggy and buggy. I have had them both apart and the Dynamite is just like the Z852 not the red head. In my opinion the S852 is perfect in a truggy, awesome bottom end and great top end. The Xpe in my sons truggy runs very well also, he gets quite a few looks as it really rips on the top end.
I have not ran the red head yet, I have had one apart and did some measuring on the port timing etc. Just a little modding and it would rip as good as the Z852. I will probably run one in my buggy next year.

Lovin this engine so far even with grp 20503 im gettin great power bands. Im still fat im runnin 207ish range but will be leanin it a bit this friday. I got over a half a g on it and i think its ready for some more heat. Last friday i got a good early lead winning on a small track and had a bobble leading to crash and lost the guys. Still had a great day though, going from b main mid pack average to a main average is very impressive. also nice to not have a flame out or anything which i have had happen almost every race before this engine. I would have to say kudos to the dynamite and Alpha team for making a great engine for a great price.

anymore updates on this engine

Yes will wheel a truggy just fine. 2 of my friends run them in truggy, they both scream and run very nice. Only thing ive had with this engine is my top needle o-ring want bad and made the needle really easy to loosen, but 25 cents laiter that day and it was the end of it. Never had it happen again since.

if you have an old Nova engine or carb laying around, the high speed needle fits, the hole piece... and IMO it made my Alpha a whole new animal :nod:
