ported inlet manifold

Hi guys, all new to here so just working my way around it still. I have built track cars in the past and I found good gains from modifying the inlet manifolds!! I'm just wondering has it been done on the 300 lump?? Obviousy they get all gunked up with ****e and they will always benefit from a good clean out. But I used to cut manifolds open with a band saw and then port and pollish them all out increasing the size of it slightly and allowing the air to get into the engine faster etc. Made a fair bit of difference on the ones I've done in the past I also used to do the ported and pollished butterflys and throttles.

its a tractor engine not a race car……..if you want more performance sell the 300 and buy a V8 or do an engine swap with something more gutsy

Have you wound up your boost or played with you pump attal dr evil??

you get a slightly faster tractor thats about it

Just noticed your avatar so I'm guessing that you have a v8!! Which also isn't a race car so I'd never bother with them only good thing about them is they sound lovely!! But its not all about speed its about having a reliable economical engine and things like that will help the engine to breath easier

I have a V8 but its not up and running fully yet, engine runs but thats no use without the body bolted on


The difference is its a disco V8 in a series which weighs a lot less so that makes it faster! I was thinking more along the lines of a 6.2 or a 4.2LSE if you want power and speed in a disco

And a mortgage with shell garage lol

wont be no more expensive than my 300!

What you mean???

I get 15-28mpg on diesel depending on town or motorway…..v8 wont be much worse on motorway and cheaper to fill the tank, town will be worse but I can live with that and LPG at worst

What was the run time on that running V8.......... 45 seconds Think you got more to do than just bolt the body on

Show the newbie some photos of you creation, Nick named frankenstein

Yes because you don't want to run a V8 without a radiator plumbed in for longer than that do you :doh:

How many years does it take to put in a radiator?

That depends on how much time you can be arsed sparing to do the work…..considering I'm not running a standard set up by any means.

The slam panel is custom as is the radiator now as I didn't like the way the original fitted
