Default LRP ZR.30 X Competition in a SC8?

Right now i have a brand new LRP Z.28R Truggy Spec 3 in my SC8. I never broke it in and was thinking of just putting it in my Turmoil Pro buggy and buying the LRP ZR.30 X Competition for my SC8. I read that it was so powerful that it was busting different parts on Savages. DO you thing the SC8 parts can handle its power?

i had the LRP .28 spec 3 in mine and it did awsome a lot of power the only problem was it sucked for fuel, a 21 would be best if you plan on racing but it will handel a .30

that is way too much torque for an SC8 IMO, you will loose traction a lot

on that, i would rather get a fast revving .21

Even though ur the second person to suggest a 21 its either gonna be the lrp 28 that's in it or the lrp 30. I'm mainly a basher but I plan to try racing at a local track which I think allows 28s and 30s. My boy put a LRP 30 in his savage and said it was sick. If I was keepin my LST2 I would love to throw a 30 in it. I'm also thinkin about getting a truggy so maybe ill throw a 30 in that. Who knows.

that is cool, I have a picco .28 that i'll be putting into my buggy, overpowered bashers are fun

yeah its got small tires and buggy/truggy design I think it would handle it, but that's just my 2 cents

I've had a Novarossi 528XR in my SC8 and i found it way to much power, The original TTr.28 is perfect for racing the power delivery is great. The JP1 pipe really wakes the TTr .28 up but it does drink a little more fuel, Im just about to try the TTr 2035 with a long header and short and see which is the best combo.

For bashing tho the LRP 28 would be more fun due to the slightly more rpm it would have, Or run the 30 and put an extra tooth on the clutch bell.

I just bought the 30 for my SC8. I plan on running 18/44 to help offset some of the torque. I'm also going to run the 7.5 venturi and adjust the power curve on my DX3R. Hopefully with that combination I will be able to race it with authority without being too wild.

the LRP ZR30X is a mnster of power. I've run it in my Hyper 7 PBS, and for racing it was uncontrolable. But for bashing, with proline badlands tires, it was sooooooooooooooooooo funny

I have a LRP .30 sitting here waiting for my SC8 as well.
Part of me says to wait for my Pro .28 to give up the ghost,
The other part says its waaaaayyy too much motor for my driving ability. LOL
Gearing it up is a good idea. I may try that when i fire it up.
Post up again after you run it, Im curious how it responds in the SC8.
What tires you going to run it with?

A good .21 will have alot more performance then the LRP 30....in the SC8 chassis they will have about the same torque, then in the midrange the .21 will take over and on top end the .21 will literally blow the doors off the LRP 30........ I have a LRP 30, it has decent torque, but doesn't have a very good RPM range, it is really just a MT engine, it works good in a heavy truck as it has the grunt to get things rolling, but in a single speed center diff application you really feel its lack of RPM.....

I've review the LRP .30 few months back for my website -> http://www.myrcbox.com/?p=1475

This engine is extremly powerful. To calm it down a little bit, I suggest you to use a bigger clutch bell and if you can use a smaller spur gear.

There is no problem for the drivetrain, it will resist all the power delivered by the LRP .30 engine.

Several of us are running the LRP .30X's in our SC8's without issue. The added torque allows you to gear them a little higher than stock and they will destroy .21's pretty much everywhere on the track. Over Labor Day weekend, Saxton's SC8 with the LRP .30X was absolutely insane fast on the straights! I had one the following week and have been extremely pleased. Idles nice, tunes easily and has awesome power.
