i just put my 5 port turbo into my truggy and thats where its staying that thing has way too much bottom end for a buggy

If you run the 5 port in a buggy I would try a couple things to make it manageable. Try 1.0 springs, a high end pipe like an 086, and maybe jump up a tooth on your clutch bell. You can also run a restrictor. All these combined will help tame the beast!

i ran 1.0's ran a msr1005 pipe and it was too much bottom its great in the truggy though so thats where it will stay

for a truggy would the .21 5-port race engine (turbo) be a good choice?

It really depends on the size of the track and the traction conditions. I am racing the 7 port with 053 pipe and have won the Amain the last two race weeks in a row at our track. The 7 port has less torque on the bottom end then the other motors I am running against, but it allows me to drive so smooth through the tight sections of the track, that the guys start pulling me in for 4-5 turns in a row, but can't do it for the 6-7 needed to catch me. A lot of their torque advantage is wasted by spinning wheels or accelerating so hard that they push through turns. I then pull another 20' lead down the staight away and it is all over. One of the guys has the 5port and it definitely has more punch, but the track is outdoors and gets a bit washed out, so traction and putting the HP to the ground is more important than all out torque. Unfortunately I was away when they had the big multi-state race a few weeks ago where a bunch of fully sponsored guys showed up. My fastest lap times in the last two races were only 0.8 seconds off the pro times!!! This would definitely not be the motor to get on a hard packed tight track though and I am still tempted to get a 5 port later this year to see if I can put some of that extra low end to work to shave off a few tenths.

That is exactly how I like to drive, like to be real smooth in the tight sections. That is how my RR is. I think your explanation was exactly what I was looking for. I am running with Novarossi's, Ninja, RB's with my RR and am the same as you with them spinning alot from too much torque and pushing and I can stay in front, not a packed track either and is real loose.

The 5 port is a great truggy engine, really doesn't lack anything, but for my taste the .25 is the key for truggy, it has a bit more bottom than the 5 port .21 and just as much top if not more, with .21 runtime. i have seen and felt that less throttle input is needed to get as far, it put' the powerdown very well and is Nat's worthy.

The 7 port turbo is also a great truggy engine, it makes more bottom than people relize, good clutch set up and a 053 pipe and you will have a monster on your hands.

The 7-port feels like it has more torque than my Axial RR and also my SH .28 I had on my older buggy. I cannot wait for the next track day to really run it and see. I have not even leaned it out yet! Power is killer now at 175 degrees.

I think their is a problem with GO carbs, my engine does not get hot at all, I have had close to 12 litres of fuel and I still cannot turn the engine by hand, even when it is stone cold with glow plug out.

I have just installed an OS VG P carb today and sealed with silicon. Will report back on how the VG carb performs in GO 3P R Spec later.

That is the sign of a good motor LOL! My picco .28 has about 30 tanks through it and it still gets stuck at TDC and have to use a screwdriver to free it up to get the starter box to turn it over.

os carbs have a smooth feel on the GO engine, The NR carbs have a bit more grunt to them, like the old style LSN go carbs. thats what I'm using in the 3 port.

Smooth is good for me, as I need to learn more throttle control. Hopefully this will make it as smooth as an OS Speed engine. I only wish.. By the way if anyone is going to use an OS VG P carb does it not come with restrictors so the 8mm restrictor will not fit, but if you intend using the OS V Spec carb the restrictors will fit as they come with 3 restrictors.

did any of you notice that amain now has the .21 3 port race in stock?

I really like the new logo on the box!!

The 3 ports A-main has should have the black case and the new logo on the head. The ones I just got on my order are the new ones in that box. I only have 2 left to sell.

Rex

yes make sure they have the black case on them. My order had the black cases too which are the new ones. I already sold my 3-ports and ordered more!
