this has basically no bearing on this thread, so mods delete if you feel it a waste, im just bored at work. i have a .21 8 port in my garage with the glowplug threads stripped, is it worth it to just go with teh turbo head/button now? also, i have the older .21 8 port i believe, its the purple head, is the black head the "race" version?

RE: Hyper 21 8 port...good engine?
I think this pertains to the topic
So what is the correct operating temp for the Hyper 8port. The first one I had in my Hyper 7, i ran it in the mid 260-270's, which was recomended in another forum. The head quickly turned from purple to toasty black. eventually I think I riuned that motor.
The paper with the motor says to not to exceed 140-150C, which is like 300F. I was planning on racing it around 225f. I will be running 20% O'Donnel fuel and an MC8 plug.
Thanks

Do not tune to any certain temperature. Tune where it runs the best with good smoke and with in the maximum temperature.

The Hyper 8 port is a killer engine, and my very good friend TazerVersionA's post is what I have learned from my testing with this engine. I have won expert class races with it more than once and here in So. Calif., and thats very difficult to do, because the quality of the drivers here.
The midrange needle can for some be difficult, but if you learn it, and how to control it you, will come to love 3 needle carbs (I wish they came on every engine personally). The best method for finding its setttings is to remove the entire high speed needle (housing and all) from the carb body. Then look into the hole and you should see the midrange needle hole, the midrange needle only has four holes on it and, you want to make sure to have one of them lined up with the high speed needle or it won't run and tune correctly...It doesn't have to be in the exact center (I've heard of some turning out the midrange needle like 3 turns thinking it had to be directly in the center of the high speed needle housing hole, it doesn't) of the hole. How I adjust mine is this. I'm normally one quarter turn out from flush, centering the holes and then marking the carb body with a file to mark where the adjustment needle must be set at. You can only make quarter turn adjustments on the midrange needle, and thats why I mark the carb body, so its easier to know for sure that its set correctly...When in doubt about the o'rings, just replace them, they aren't expensive. Part number 53061 and its $8.95. If you notice the midrange walking, then replace the o'rings and you should be fine..
To resolve the bearing issue I installed the front bearing from a Picco .21 (part number is 51311 and its $29.99) into only one of mine that had issues with the front bearing. The other 4 or 5 ran like rabid dogs for many gallons with no issues at all.
I run the exact combo my friend (TazerVersionA) above posted and can't stress enough how fast this $200 dollar engine/pipe combo can be...

This engine rocks and the pattern of carb o-rings failing, I noticed were on the RTR buggies.

ROB!! Thank you!!! Lynchmob showed me how to set mine and I gave these exact tips on this very forum like a year ago and was flamed big time! Even though I did it and had experience with it, they still claimed I was wrong even though they had none.

I agree 100%.
Lynch has been home with his baby. I haven't seen him in a few months. He seems to be doing good and is happy. I will pass the word along!!

There isn't a Turbo head for it, besides using a NovaRossi P5 Turbo head button and head (which will fit). It has "turbo" in the name, but it isn't a turbo engine. Get a stock head and run the snot out of it...You can choose from the black, purple, or the champange head...They are interchangable...

RE: Hyper 21 8 port...good engine?
we have a new hyper 8 with a hyper .21 8port engine and the thing runs great. break in was a little finiky as most engines are but after break in just set it and for get it type of tune. i set the motor up here at my home and we just raced it at a track 300 miles away and i didn't have to retune anything ran like a champ very consistant and fast. motor temps stayed around 200 degrees during 30 minutes mains and was pulling all the high end motors on the long straights. very highly recommeded.

RE: Hyper 21 8 port...good engine?
Back to the topic...
I broke in and raced my new 8port this Saturday. Motor ran perfect all weekend. It was a little tight at first, needed to losen the glow plug to allow the starter box to turn it over, but I was also running it a little rich.
I broke it in using a method recomended in another forum. Heat cycle 5 times for 2-3 minutes running at about 180-200f, allowing it to completely cool between runs. Then heat cycle 5 times for 3-4 minutes running at 200-220f, allowing the motor to run through the rev range without going WOT and cooling completely bewteen runs.
I also set my mid range needle per Nitrohouse's recomendations in this thead.
By the main event, the motor was as quick as any in my class (one below sportsman and one above beginner - first time at the track and with a new car)
Also, for those worried about the weaker mid range. I found it quite nice. There was a rythem section that requred you to keep car to be at a constant speed to keep it on all four wheels. Acceleration or deceleration would upset the car. The smooth(abiet weaker) mid range let me accelerate to a good speed then keep it there to let the chassi do the work over the rythem. Others with more powerful motors kept getting out of shape due to constant acceleration and then letting off the throttle and would end up kartwheeling across the section.

You will want to gear down for tight tracks, not up...So you will want to run 13t bells or even a 12t for really short tracks. I recommend using 1.1 springs for the clutch, it will give the engine all the punch you will need...

The 20E is a 2 needle carb.
The stock settings are HSN 3 turns out from fuly closed. LSN is slightly in from fush (about 1 turn).
Its a good little carb, keep it safe

Good little engine. Mine's still going strong...top end screamers...
Hincappe, welcome to my ignored users list, you join an exclusive group of people (only 5 since I joined this forum), whom I have deemed such trolls as not to be worthy of my wasted life reading their pointless posts. Congratulations.

RE: Hyper 21 8 port...good engine?
Its OK bottom end but no more than that. It makes most of its power at high revs.
If you have a short technical track then be looking at different engines.
