I have a tecumseh 11hp motor, and i want more performance.

[thatkidrob]

i have a Tecumseh 11hp motor, it runs good, but the parts are hard to find and i wouldn't mind a little more performance. Is there any problem with running the exhaust straight out (no muffler). And any suggestions maybe for air intake?

 

[2or3wheels]

what do you mean by performance, power speed? both?

What kind of tec. is it? a Snow king? If so, i added a few goodies to mine to make it more powerful.

I believe Tecumseh star racing parts fit, go the the forums at www.4cycle.com and ask.

its a power sport engine and i want more mid to top end power (although i must admit its already quite fast). but i also need to find a new air intake because i cant find the Tecumseh air filter ANYWHERE!

Powersport? If you want more power, you're better off starting from scratch. Briggs 5HP, GX200/GX160 Clone, Animals, Blockzillas....

Take blockzilla's off the list. There purely race bred alcohol engines that burn about 1 liter of alcohol in 20 seconds.

im not looking to spend hundreds for a new engine, im saving up for a pit bike so there's no way im buying a new engine, all i really need is a new air intake cause i cant find the filters. I'm pretty happy with the engine, im considering making a muffler for it.

Only with a huge carb and a crazy cam, IIRC(briggs site seems to have lost its blockzilla page) you can put stock 5 hp parts in one and have a normal 5 hp with a heavily reinforced block.

Pic yourself an adapter and airfilter on ebay.

Weld yourself up a straightpipe or trumpet pipe. Drill the jet on your carb.

That should give you noticeably more power.

thanks magice thats exactly what i was thinking about doing.

Why'd you spend $200 in a block and put parts that rev will 5000 in it? ut:

A cast iron 5HP bore is plenty enough.

Actually Oscar a BlockZilla block is $800 bucks and thats not even ported yet. And yeah realy would would you spend that much money and only put in stock parts!
