how's my briggs running

[robin]

you would save alot of money......

my point was that his ride has (from what i have read) aprox 150hp per liter witch is nothing to get excited about

many engins put out the same amount of hp stock and much more

my kx 85 has just under 300hp per liter stock and runs on pump gas

i do think that it is impressive how power full his motor is. what i don't see the point in is why spend xxx amount of money on it to get it to the same power levels as other redialy available engine s ?

Wheres the challenge in that?

Say AYE!!!

A KX85 is a liquid cooled 2 stroke, it makes double the power of a 4 stroke just because its a 2 stroke.

Ahem, It's not a polished turd. It's a blue printed block and is ALOT larger than a 5 hp block. The last time I checked it wasnt me burning like 3 jugs and 20 pistons. It actually runs very good and if you heard the kind of thump rumble from it you wouldnt be talking trash.

 

[BradenM]

Robin your arguing against facts. You can't win. That makes it an impossible challenge. "Challenge" is starting with something that produces a small amount of HP, and something that not many have done, and then trying to do it yourself. Most of us are not too concerned about where it ends up, for we would rather spend the money bringing a 5hp briggs to 7hp then simply buying an 8hp. For the challenge, the enjoyment, and the feeling of accomplishment.

It's not the destination thats important, its the journey.

 

[jr dragster T]

Thank you Braden! It's a big acomplishment to make 60-70 HP from a 5 hp style block.

 

[modelengineer]

I would think if you have the money there is almost no challenge at all. You just buy the parts and bolt them together. Bit of tuning and there you are, 60-70hp.

Doesn't seem all that different to buying a more powerful stock engine to me, except for the extra expense involved.

 

[robin]

sort of my point its alabout how much ££ you have to spend

it would be cheper to get a 60hp engin than buy parts to get the same power from a lower power one

LMFAO! Just because it's sold as a kit it's realy not a kit. Tell that to me and the guy that built it. He'd laugh his *** off then hang up. Theres lots of work to be done. Theres lots of machining and clearencing and cam timing, Ignition timing, Major calculations, When building a racing engine the sidecover comes off and on about 15 times for checking clearences and timing. Thats actually kind of offensive saying it wouldnt be a challenge jeez.

 

[modelengineer]

I didn't mean to offend you, sorry.

I just don't see how it's that difficult. You buy the kit ($$$$), pay someone to machine it a bit ($$$$), then assemble.
Cam and ignition timing, unless the blockzilla uses some insanely complicated adjustment method, is not all that difficult to do.

Major calculations

???

 

[jr dragster T]

Omg dude, No all the machining isnt done and we helped with all the machining. All you get when you buy the block is a block with seats and guides. Other machine work is for you to do. And if ya didnt know our engine builder has about 2-3 pages of calculations and information on each and every engine. Like where the piston and cam degrees and angles are at each position of the stroke and other calculations. I think people would understand me more and my hardwork on 4cycle.com.

 

[BradenM]

Probably stuff along the line of what flexes at what rpm, will it make contact with X at such a rate of flex, how much flex before breakage, e.t.c. Funny stuff happens at 9krpm.

You nailed it.

Ah, I see now. That would explain it. I thought the block came finished and you just filed it at bit for clearance. I stand corrected.

Just out of interest, how much has you're Jr. Dragster engine cost in total, including the machine work? I will understand if you don't feel like disclosing it, I would just like to know as a matter of interest.

 

[jr dragster T]

The engine total was $4000. Normally engines are sold with the appropriate clutch which is $1000. So you can say for one of the biggest and bad *** drag engines with the clutch is around $5000 then the setup need's to be tuned. I get alot of my machine work done for free. Infact out of that $4000 none of that was money for machining. That's all parts. If we had to pay for maching time it would have costed around $4800-5000. I help the guy out alot in the shop and around his house and where all a group of freinds so its all good. We help him build his deck and all and he helps with machineing. One big happy family you could say.

 

[BradenM]

^^ Thats Canada for ya!

 

[jr dragster T]

Lol what part about it is canadian?

 

[modelengineer]

HOLEY MOLEY, that is a lot of money. But I guess it is heaps of fun competing at the drags.

For that much money you could get a v. low km GSX1300R Hayabusa engine here.
Mmmmmmmm, 180hp stock...

 

[BradenM]

I CAN GET A HAYABUSA FOR THAT!!!!???? **starts saving**
Tyler, what I meant was that Canada's a friendly place with relatively low crime rates-would be a great place to live.

 

[modelengineer]

Remember, he is quoting canadian (presumably) dollars. Here you could get a Hayabusa engine for less than $6,100 AUD ($5,000 CAD).
