More Power from an F-Head

Yes, that has to be right ... I got it backwards.

 

extreme4x4 just ran a section of show on the Jeep class of swampbuggy raceing. Not sure how they did it but the guy was claiming 150hp out of an F-head spinning 7200 RPM So apparently it can be done. And yeh I was thinking if I ever get to do a turbo that I would do a turbo for a honda 1.8L motor. Small turbo should spin up quick.

 

Tim & Steve.....I will see if I can take a couple of pictures of the turbo's on the engines with a ruler next to them and maybe that will help to see if these are viable options. I do not plan to build or run an F head anytime soon but I think it is a neat idea.

 

I actually have a crazy offset cone on it now. The other one is a baby 4" I think on a cheap aftermarket chrome base and lid. I had the cone rolling around my van and tried it on the stock elbow. lil modification and it werkz!

 

i saw that show. It had a 4 barrel carb adapted to it. im suprised it ran at all with all that fuel R)

 

Jp did an article on those crazy sippy hole jeeps a couple of years back. showed some good pics. sheetmetal intakes, 4 barrels, crank triggered msd ign., hydro. linkages, waterproofing. iirc, someone on here wrote it. maybe, they got some secrets they could share.

 

I am new to the forum, in need of advice on my F-134. Please email me at 03ultra@mtaonline.net

 

You state that you had the cam timing advanced, I'd read this before in one of the racing mags.
How much did you have it advanced? I know it can't be more that a degree or two. Or a tooth or two with either the chain-drive or direct-drive cams.:?

 

a degree or two is correct, a tooth would be too much, not saying it wouldnt run, i have seen that happen once, from the factory, on a tractor, was always hard to start, we did this on a sbc, and its actually works backward to what you would think, retard it a degree or two and all kinds of top end, advance it and all kinds of bottom end, not sure how you would do this on a F head, our cam gear was special it had a ecenrric in it and that was how you set it

 

And not worth the trouble

 

needs to place an ad or pm

 

After looking back at this post and after doing the engine rebuild the jeep is cool in a way all its own. You dont need any more power in them, lifted and 33's maybe but all by themselfs they are way sweeter than a huge cj7.

 

No argument really. But, a good flowing exhaust (~2"), a masterfully built Carter carb or a Weeber, an MSD 6 box or Pertronix and an extra 3°+ of initial spark makes a BIG difference. At some convenient and economical point in time, I am confident that a milled head and a Clifford type cam grind would really be appreciable gains for me.

 

What do you know, thats exactly what shes got now.I cant wait to get back on the road.

Hey just a quick question, does any body name their jeeps?

 

My jeeps name is Kilroy

 

one of the tricks the old hot rodders used to do when changing cam timing with a stock gearset is to take the key (of the cam gear) and cut a sliver off of it and move that sliver over to the other side, which in effect degrees the cam. we've done this a few times on older hot rod motors at our shop with good results.
