Status: offline 		The Sprint 2 isn't made to haul @$$ with the nitro cars, it goes like 30 stock, and most people say the belt system can't handle a lot of power. My RS4 3 18SS is twice as fast as my Sprint 2 out of the box, but I use the Sprint 2 for drifting. A kit electric car like the cyclone could probably run with a nitro, but the RS4's are fast out of the box!

Status: offline 		i know this isn't an hpi but my tc4 with an hvmaxx brushless goes 70mph without all the nitro hassle and has super nitro speed and nitro run time.

nitro isn't the only way to go fast. electric is faster!!

Status: offline 		Well, I wouldn't jump to the conclusion that electric is faster. Its definatly easier, but a ported small block nitro engine or even a big block (mabey) should easily go 70, but I highly doubt a Sprint 2 could go even 60.

Status: offline 		I know this reply is a couple of years late but hey better late than ever..

I have a HPI RS4 Sport2 and I believe the 4 wheel belt system is very similar. I am running a Sektrum Transmitter & receiver & servo with a Novak gtb/ Novak Brushless 3.5/ with a 4800 Kokam Lipo/ which equals to a **** load of power. I am pushing 70 easily (no problems so far). Running with regular matched cell batteries (3500) I had it clocked at 57mph at a drag strip held by a local hobby shop. The LiPo makes a huge difference. Before turning a 3.5 w/LiPo on to a sprint I would suggest upgrading some of the parts (aluminum shocks, swaybars, one-way diff up front, metal geared servo) and you should be fine or alone at the finish line for a few seconds.. :^)

although Nitros are alot of fun too, they have a down side to their power.
1. All nitro motors will wear quick due to heat (as with most small combustible engines)
2. Parts are more expensive
3. Very seasonal unless you have an indoor nitro track (rare due to the fumes)
3. noisy so be ready for the phone calls if you live in a quiet neighborhood
4. Must be a fast ass runner if you flip it far from where you are standing (fuel will spill all over from the breather when turned over)

So in conclusion if it's speed you're looking for and not nesseccary how it's powered I believe there is more bang for your buck in an electric and yes they can go faster than a nitro. Currently the R/C onroad speed record is held by an electric setup. For now.

Status: offline 		Well I hope the Sprint 2 is a good car.. I just ordered the sprint 2 sport toureza and am hoping to learn to drift. I know nothing about electric so would like to know what I need to do to it to drift....

Status: offline 		Lol I remember this post.

My Spring 2 goes at leats 50, probably 60 now with a brushless motor on lipo. Its all good, but the rear belts to go every once and a while...

Regarding the post by MTboy, its a good car. It will drift good with drift tires. With a little bit better motor it drifts great, and you can lock the rear diff to help.
