What are my options with throttle bodies? - Saxperience

Barry123 · 5th May 2011, 13:44

Yo yo. I know this has been covered in detail but I don't care.

What are my options for Tb's... as in what manufacturers are out there that do direct fit Tb's for the J4?

Jenvey?
AT?

Anything else?
It seems favour for the AT ones has gone off the boil from what I've been reading... what was the reasoning behind that (if any)?
Do Jenvey still do the curved trumpets version? Are Jenvey ST's one pretty much direct fitment or is there still that issue with the throttle mechanism?

What have I missed?

I'm not interested in bike bodies or anything like that!

Cheers,

I like my AT's

Barry123 · 5th May 2011, 14:10

this is what I don't understand... why have people rubbished them?

Bike bodies seem to be very popular at the minute and seem to be cheaper than most DTH throttle bodies. The K3 GSXR 1000 bodies seem to be the most popular and then matched with a Colin Satchell inlet manifold. PM Sandy about it, the results seem to dictate that bike bodies get better results (especially when mapped by Sandy)! Even his race engines running ~220bhp use them so they must be decent! They are also supposed to be the most reliable - butterflies don't need re-balancing often.

I would personally go for bike bodies and with a Colin/Sandy manifold they are pretty much DTH. The noise from them is insane too! Your looking around £600-£700 depending on how much you can buy the bodies for (most on ebay are around 100-200).

what Harv said...

The AT tb's seem to have fiddly/funny not very user friendly idle set up from what I've seen.

there may be a group buy going ahead for jenvey bodies if you haven't seen

most that slate them may not of even owned a set, when myself and andy hammond fit mine only issue was throttle being sticky and fiddly little bolts.

fit and forget! they look better than any other bodies for a saxo!

nothing really wrong with the AT ones, just if you want a long induction then the angle is wrong

raunchz · 5th May 2011, 18:35

I'd personally go with gsxr/sandy setup or the sandy inlet and dcoe Jenvey bodies

I did a big thread about them in the premium how-to section which I suppose a lot of people miss being non-premium.

I'll try and copy it over onto a non-premium thread

As far as i know, GMC were the ones who sold the curved boxed jenvey setup and john doesnt make them anymore... now i emailed jenvey and they only do the ST ones now... (if you find out different please let me know via pm) (Most expensive - £1,316.40 NEW)

The Atpower ones, people seem to have issues of how close it sits to the brake bar as kam said "the induction angle is wrong" if going for long trumpets. Look the best and you can choose the colour which is nice....(£834.00 NEW)

Sandys bike setup can use K1,K2,K3 OR K4 GSX1000 bodies and yes he will tweek them to fit standard pico type injectors and use various sensors etc... and obviously a manifold and a set of trumpets to fit... very good results and he can also make them to have a filtersetup..(Cheapest - £500 + Bodies (so an extra £120 - £180 )

Sandy also mentioned he can adapt "TH" jenvey bodies to fit the TU engine.... (£800.00 - £900.00 Depending on spec)

Here is a reply from Jenvey about the difference between ST and TH

Quote:

You will get more power from the single ST bodies. The only reason of using the DCOE style bodies is the price. The engine has the bores at 86mm so you will have a curve in the system to use the twin bodies.

I have not really researched the kms ones..

Before my engine problems i was going to go for the sandy setup as the curved jenvey setup i was going to purchase was sold and jenvey kits are expensive (unless kam does a great deal in the group buy thread)

J222JRA · 5th May 2011, 18:53

The fact that Sandy Brown swapped from jenvery bodies to gsxr bike bodies on his race cars says it all to me.....hence why ive gone for bike bodies with the colin satchell conversion. Its a direct fit kit.....keep an eye on my thread.

dannygti · 5th May 2011, 18:58

get jenvey sf's if you can stretch to it ad. ( the single seperate ones)

if not then id get the gsxr setup sandy does

Adam Jenvey SFs do it (has yates sold his kit yet??)

Personally i wouldnt use the AT ones due to the angle of the Inlet tract and the fact well they just look shite compared to a nice set of trumpets

raunchz · 5th May 2011, 19:12

Isn't the angle of the Jenvey sf/st setup similar to that of the atpower setup, so aiming at/just above the brake bar?

Meaning if you want a long induction length then you're limited to the Jenvey/sandy dcoe setup or the sandy/coming gsxr setup, and then can cut the scuttle to get a nice cabin noise !

The jenvey set up is dependant on the inlet manifold.

So you could even have them pointing down if you designed an inlet manifld to do so (see the sandy DCOE manifold vs chadl). Now the AT ones the actual butterfly assembly bolts to the head without an inlet manifold, it could be sorted with curved trumpets again but alas no one seems to be producing/wanting to produce a curved 'RAM' pipe for the screw on system to fit to.

raunchz · 5th May 2011, 19:30

The chadl manifold points the sf bodies at the brake bar doesn't it?

The Saxo Vts kit uses the chadl inlet.

Ryan^p · 5th May 2011, 19:42

didnt look like it would on my kit but i sold it ages ago.

Ill try and find a better pic but certainly looks like theres more space to clear it

Yes he sold his kit, ecu and his exhaust to someone off here as far as i know... as i told him to message me if it fell through as i only wanted the bodies.....

so the jenvey SF kits are curved and can use a box? more research me thinks....
