Thump RC GT2 four stroke conversion

[thecool11223344]

is it 4wd?

[SUPERFORMIAN]

This isn't an Inferno GT2!!!!

[durokrikava]

where did you get this cooling fan from?

[SuperSweeny12344]

Why are your back tires all ripped up???

[JimmyZSweet]

Ever consider what a Micro Turbo supercharger would do? Not saying it needs the power. Considering it has actual poppet valves and a turbo could build positive manifold pressure without evacuating the entire combustion chamber before the compression cycle, I figure itd be interesting to see. Nice job!

[cockmaster024]

awsomeeee

!!!!!

[dedasdude]

those tires must have torn apart.

[motabikeboy]

ALMOST sounds like a chainsaw.

[alex2121rccars]

[TrikeLovin]

What size engine do you have in that beast?

[nitrorcman108]

ive been wanting to do something like this on my traxxas rustler since ive made the 3.3 conversion and been looking for more power. i just need to learn a little more about the setup.

whats the difference in the four stroke engine any faster

[MrFubs]

all 4 stroke engines in anything have more tourqe than 2 stroke

[JuicyFruitFresh]

Nice! How are the 4 strokes on reliability and power compared to the 2?

[ThumpRC]

I also have the exhaust headers welded in place to keep that from falling apart. It's expensive, but very worth it to know everything's going to stay put during a long race.

[ThumpRC]

I had some port plugs machined, then after inserting and bonding them in place, I take the heads to a CNC machinist to have the new port and fastener holes drilled and tapped in the side of the head. I also had special intake manifolds and carb adapters made to match that will work with any 1/10th scale carburetor.

It does need a cooling fan, otherwise it overheats the valve springs and ring, causing them to lose tension (bad).

[kierankillerfish]

How did you change the carburetor location? Does it have to have a cooling fan I've always wanted to put one of those rb concepts superchargers on one of these.

[syedjaafar]

sounds like 2 stroke..maybe your exhaust..

[Crazylogie]

sounds nothing like a 2 stroke..

[Spashdown]

I love these trucks, i have 4 of them. That is a badass ride!

[30GB]

wow i really like the way you made the cooling fan

[golem72002]

have you tried the Fs 52 valve springs ?..

they're the same diameter outside and inside as the 26 but they're 14mm vs 12mm for the 26 cx?

[RiceRacerH8R]

Nice conversion but too pricey...good luck.

[ThumpRC]

Thanks. I will have some more race footage to upload soon! 2009 was a much better year for me in Wenatchee - I took 2nd place in one of the most exciting race finishes I've ever had the pleasure of being part of!

[tadracket]

Dude, this is soooo nice. I have read your 4-stroke Revo thread a dozen times. I have a 52 in the garage and a t-maxx that begs to hold it. Even if just for a tank or 2. I may play with it this summer. If I ever get in to the GT2 scene, I will be looking you up for a kit. ;-) You are top knotch, no doubt.

[ThumpRC]

Yes, you can buy the truck and engine at any hobby shop. The kit to make it all fit together is on Ebay. Search for "Thump RC" and you'll find it.

[azzzzzzaazaz9]

hi did you but the car and the coms with it thanks

[dp250f]

About 40 MPH on open pavement. Check my other videos to see it on a race track.

[showme85]

how fast does it go ?
