Throttle Body?

BWAHAHAH

classic.

Good thing for the Magic cards or I might've shot myself reading this thread. POOK just pick up Slater's TB when it comes out and don't worry about it. If you really want to mess with your intake manifold, extrude hone it...don't port.

it's easy enough to port... why not? it took me about an hour to completly cut it out with a die grinder and smooth it into the inside..... and that's with taking food and piss breaks too!

[Zulu]

Well, you don't want to smooth out what you've ported within the intake manifold...you want it rough for velocity. So no polish...and porting the manifold only allows you to get the very beginning and end of the runners leaving the middle as a restriction. It's an improvement, but ideally you'd extrude hone...well no, ideally you'd make a straight runner or ITB.

Speaking of, anyone ever tried an ITB setup?

haha, straight runner, you funny. ITB's would be insane, but the only engine i've seen it on would be the btcc engine.... *turns head to volvo gods* please send me a set of ITB for my 850 this christmas, i would love you so. *back to reality* like that'll ever happen.

i don't think someone with a tig welder would have a lot of difficulty adapting a set to the stock intake manfold, or creating another one entirely...

now would it be best to use a set of ITB's around a surge tank design or a surge tank with individual tuned plenums and a single throttle body. why is which one better then another?

[Swedish Mike]

I think ITB´s works best on N/A´s, no big gain on turbo cars. The Skyline guys remove the ITB´s when they want to go fast. Just more stuff that can brake and leak, we got enough of that all ready.

IMO it´s a bling-bling thing to put on a Volvo.

ah, so what would work best for a turbo setup? surgetank with one massive throttle body?

[tknutson]

What about an intake like the one that ROY@VMS had made up, straight runners big plenum, nice big size TB???

Ehat would be the recipe for a DIY intake for the 850???

Where could I get the runner length calculator, plenum calculations etc?????

Would be way cool to make something nicer and not as snaily like for the volvo

Yeah ask him how that went. As we all pointed out the runners were way too big as was the plenum. He did us all a favor and confirmed it.

Its really easy to make up a straight runner intake manifold. I am still in the process of making mine. Just take a 960 intake runner and cut off the extra intake port and then weld on your seperate runner tubes that join to the main runner. Really easy and straight foward. Will bolt up directly with no problems also.

Cool, what would be the calculations for the runner lengths, plenum etc?????

And also at what HP would this be a must????

I am going manual very soon, and will very soon be looking to go 500Hp, or at least what would be the max for stock internals (at least for now.)???

Anyways, I know everybody says that the stock intake manifold is good for upto like 400HP???

But I think it just looks kinda ugly, even polished.

Would be so much nicer with a straight unner round plenum, or bendt ruenners round D shaped plenum.

That just looks sweet.

Throw on some internal velocity stacks for that little extra, and direct port watrinjection with second fuel injectors upstream of the main ones.

That would just be super setup, low boost very streetable, not too much fuel etc.

Flip a switch, and second set of injectors and the second map on the (civinco) kicks in.

Add on some water with that and the sequential turbo setup. Your on the road for low, mid, and high end torque/boost all the way.

Rebuild the engine, o-ringit, and go blowing some steam.

Prolly overdid it alittle here

Hey, who could get me an 960 intake runner.

??????

Any dealership, or a junkyard with a 960 in it. 960s had a weird two piece intake manifold.

Internals are good for 330-350hp and the manifold will hold well over 400. The head is going to be the weak area that you should focus on. For exhaust I hear just posting can improve flow up to 45% ;)

[Zulu]

Secondaries? Did he really just say that? Completely unnecessary, you will never need them. Reminds me of the kid I know who just bought a second fuel rail for his integra so he can run 700cc w/ 1000cc secondaries to make 700whp, :rolleyes:
