How Are These Compared To "real" Tb's?

Hi,

 

How good do you recon these ( LINK ) are compared to a genuine set of for example jenvey throttle bodies? Will i loose any bhp over "real" throttle bodies?

They're made by forum members Colin Satchell (eeyore) and Sandy Brown i believe. The old versions using Esprit bodies were great if that helps. Not seen the new ones up close, anything using bike bodies turns me off a little, though i'm sure they're pretty good.

 

DrS's iirc are pretty similar, or at least the bodies may be?

Very similar to Sarty's!

I was a bit snobbish about bike TBs originally, but since we've overcome the usual issues that blight them with a bit of engineering; I've no reservations about using them now, on road or race engines. Most of the actual Bodies are made by Keihin, a Honda company, and they are fabulous quality. As long as the manifold, linkages, fuel rails and tract design are properly designed, they work very well. If you hang them on silicone hoses, on a crude manifold without sorting the linkages and fuel rails etc, they can be a nightmare.

I presume so from your reply, but are these a decent total length then Sandy?

[Sandy 191]

Yes, done to my tract design.

Look pretty damn identical to mine. They definitely work.

 

And I don't see the difference between 'real' TBs; they both do exactly the same thing. So what's unreal about them? Jenveys etc are good, but why are they any different from these in principle?

 

These strike me as better value for money too.

especially seeing that they are £46mm and not the usual Jenvery 42mm

 

god damn it, why do all these good parts keep coming up when i have no money

[Batfink 201]

colin will have plenty more i am sure.....

The problem is i need it for an 8v engine. But maybe something could be done to make it fit, or to make it fit an 8v 40mm weber dcoe manifold?

Don't forget that it's not just the bodies in isolation; it's the combination of the length and shape of the inlet tract. Sandy's spent a lot of time perfecting this.

Do you mind if I ask what it is you are trying to achieve as you seem to have numerous threads all asking different questions for what sounds like different engines...

 

One was about turbocharging a standard engine, one was about a 1.6 16v race engine and they all seem to revolve around being done on a tight budget....but surely spending £650 on just an inlet set-up isn't really what 'I' would call a tight budget anyway....

 

It might help people to be able to advise you a bit better on what route to take for your chosen objective...rather than just asking whether components in isolation will work.

Hehe no i dont mind you asking. The turbo-thing was just since me and my brother was talking about how easy it would be to put a turbo on a standard road car (in Denmark you cannot get an MOT with an mi16 engine in a 205 anymore) to get some extra power.

 

The other threads are regarding the engine we are going to build for reasonable money to compete in a danish race series. I actually had decided to go with the XU 1600 16v route and i was just about to buy the pistons and conrods. But then i got an offer for a longmans 8v ultimate race head ready to bolt on, only needing some carbs or TB's so achieve good power figures. That is why i am looking in to finding some TB's. But no, i am still not a hundred percent sure on which way to go (16v or 8v) :/

 

Sorry if anyone is feeling that i am flooding the forum? In my opinion the more interesting threads open to discussion the better - its a forum?

No I certainly didn't mean in that sense, more that its easier to answer a question - especially - on something that can vary as much as an engine spec when you know what it is going to be being used for.

Didnt take your question negatively Just wanted to say, that i am not posting these questions just to annoy any of you

[danpug 1]

If you pm colin he would most likely be able to make you an 8v inlet.

[CaptainK 11]

Yes, done to my tract design.

I hope you're keeping a set for me Sandy (205 GTi6). My DTA is in the post as we speak and then just have to sort the ITBs out with you.

i felt my heart sink when reading this, cos the nightmarish set-up you are talking about sounds just like my engine setup.

 

what problems should i be looking out for then?

[DrSarty 90 1 Cars]

I wouldn't worry about that; I'd just do it right.

 

The difference in my engine from going from home-made manifold with silicon joiners & hoseclips to proper manifold was humungous. Rather than dwelling on what might be wrong now, take a leaf out of someone's book who's seen the light and come over to how it should be done.

[Baz 421]

Look at the troubles Simon (Dreamweaver) went through with his efforts at making DIY bike bodies work...

yeah cheers rich make me feel better about it why dont ya

 

what did you pay for your manifold and how did you connect it to the bodies if not with hose?

 

i'm seriously considering selling up and being done with it, its just one thing after another

[Sandy 191]

We connect the TBs to the manifold using o-rings. The ends of the TBs are machined and the manifold has a CNC machined flange to suit, then it all bolts together solidly.

so my tb's would need machining to suit the manifold

 

could you quote me for a set of tb's and manifold? via pm if you like for a gti6 engine
