Just wondering if anyone has put a ported on a bolton car, thinking about getting one...





Ive searched and havent found alot of info on this

I wouldn't think there would be any noticeable gains from this. You can't open up the runners that much if at all because you still have stock ports on your head. If you do open them up then you get reversion and turbulance from the air hitting the face of the head.

LE ports them, and they do it the correct way


Im just looking to see if a bolton car has used it and what the numbers are

I'd think that this would be more something you'd do on a heavily moddified engine.

That doesnt make alot of sense because 5.0 mustangs,2vs,LS1s, even hondas see gains from better flowing intake manifolds with boltons..

I dont see how a LT1 is any different when our intakes are not that great to begain with,,

as said before, you would need to have the heads ported to match to notice any real gains, otherwise you would get the problems stated above, I.E. turbulance etc,

Um in the other threads people are saying not to gasket match or mess witht he lower end of the intake manifold


Im talking about how LE ports it, not some hack job in his backyard


Real world numbers, from a ported LE and is anyone using it and seeing gains and what exactly is ported on them

May I suggest a PM to Lloyd?

The intake design and setup is completely different from an LT1 for every engine you mentioned.

Jordon Musser ported my intake and on my H/C full bolt on car I saw around 8 rwhp. If you don't open up the heads to match then it's pointless. You can port the whole intake manifold and leave the port exit the same and that would be pointless as well because only a certain amount of air can flow through an opening and unless that opening is enlarged then there is no point.

Yah but thats not true cause what if the opening is big enough and the flow restrictions lie elsewhere.

This should settle this argument quoted from Lloyd Elliot

"Most people do not see gains from a ported intake for two reasons.

1 - the heads and cam used are not sucking on the intake hard enough to show much of a gain.

2 - most ported intakes have very little done and is just "gasket matched". There is ALOT more to porting an intake and gasket matching is the wrong thing to do anyway.

The more radical the set up (bigger cubes, more compression, bigger cam, more RPM, etc) and the more free flowing parts you have (LS1 air lid, 58 MM TB or mono blade, 1 3/4 or 1 7/8 headers, 3" true duals, etc, etc) the more the stock intake will restrict power and the more the WELL ported intake will show some gain."

Lloyd

So, let's ask the question of how hard is a fairly stock engine going to "suck" on the intake?

What Lloyd said makes perfect sense. On a stock LT1 motor the intake manifold is not the restriction. You have bigger fish to fry with the other parts mentioned. First of all I would start with the exhaust if you have not done so already.

0 rwhp

I lost 9rwhp when I put a ported intake on my old h/c setup.

someone told me before that it would not give a gain because it wont match the heads. i have no idea never actually seen anyone do it and say what happened

slick1851

Well there you go thats all I was looking for, I just wanted real world answer

Not internet crap, you get what im saying?

ScreaminRedZ

I thought you wanted numbers on for a bolt-on car? So that isn't what you were looking for because he said it was from his heads/cam setup.

slick1851

If he is losing power with a better flowing head n cam

How is this going to help a bolton car???? Think about it

its lowing power for some reason other than it flowing better...you can never have too much intake or exahust...thats why lloyd reccomends stepped headers and a lid
