Why use a modified engine?

[SpyGuy]

On that note, I have a video someplace of a 740hp turbo'd diesel Dodge truck blowing the doors off a 5.0 Mustang on the 1/4 mile. 10.41 pass at 110.80mph.

NOW, I believe the topic was on "Why used a modified engine?" As Tim Taylor would say, "More power!!! Ar-ar-ar-ar!"

Why use a modded engine? Because the light, powerful, modded engine will make a faster kart compared to the big heavy stock engine of the same power output.

Ok gas lover. Take our stock duramax. 660 ft lbs stock. Try to get event close with a stock gas engine!.

I see a turbo or 2 in the bed!

 

[jr dragster T]

WHOA!!! Didnt need to know about the turbo in your bed!!! JK after closer inspection I see that too.

 

[Kenny_McCormic]

The whole pipe from nowhere gives it away.

what do you guys run on in the jr. class? im thinking nitro

 

[Kenny_McCormic]

Plain methanol.

 

[jr dragster T]

No nitro, No nitro needed to go fast, We run 100% methanol.

 

[Kenny_McCormic]

Your motor could probably take it.

 

[jr dragster T]

Ohh yeah it'd take it, Make some wicked power. I'm told by a profestional that with a nitrous fogger in the intake my car would run low 6's or high 5's in the 1/8 and add nitro in and thats getting NUTS!!!! Car already runs 7.60's at 90 mph.

Wow, just got back from holidays and this topic has EXPLODED!

Modelenginneer what size are those carb's?

They look somewhere between 35-40mm I.D each. Remember each carb is only feeding a 250cc cylinder in a VERY unstressed engine.

Dad just found some stainless pipe and bends at the pool shop and they gave them to him just for asking. FREE! It's exactly the same diameter as the stock exhaust pipes on the bike, so I'm going to have a stainless exhaust!

is there anything stoping your car from going over 90?

 

[jr dragster T]

Yeah I run out of gear at that speed and my rpm's are around 9000 and that's REALY singing for that engine.

 

[SpyGuy]

Well ........ time for a gearing change?

Well ........ time for a gearing change?

...that and a little more downforce dialed into the wings, and a long deserted Arizona blacktop with some crazy friends (the rest of us) to ASSist in timing, witnessing, and general merriment!

Then we wring out the rest of them!

 

[jr dragster T]

And the gut's to rev a $4000 engine over 9000. It's actually pretty scary at 9000 RPM.

 

[Jerryburger]

...that's why you bring up the gearing! No longer a 0-90 beast, but a salt-flats racer! (or once you 9000 rpm, let off.... 90 mph is plenty ****ed quick enough for any kart!)
...talk about peeling one's eyelids back. My friends and I have done top-speed runs on the Sportsters, and the force trying to pull your helmet off is nuts!

 

[SpyGuy]

90mph for a kart? Naw, that ain't enough .... I'll have to see about finding that jet-powered go-kart that pulled 220 down a 1/4-mile .... The picture I saw had the front wheels a good six inches in the air, blasting a good long flame out the rear, and the driver (pilot?) hanging on for dear life.

Now that's fast.

Jerry, where in Arizona? I'm in Tucson.

 

[jr dragster T]

First of all I'd like to see any jet cart do 220 mph in the 1/4 mile. Second of all no track would allow this.....Even the most slack rules. 3rd of all if the front end is off the ground from a thrust type take off theres something wrong.....REALY wrong. Jet engine is supposed to be angled downward's around 5 degrees.
