New DTH (direct to head) ITB's

[J o n]

I'll shortly have a set of these bad boys on my 17poooooooooooooooooooooooo, so look forward to reviewing them against my old Jenvey kit I recently sold.

The creators AT Power believe the power output will be 10-15% more than the Jenvey DCOE set. On a Zetec or Duratec (cant remember, I did speak to the chap that made them though) they had done back to back runs of each, same engine, same day, same dyno and the DTH ones were making the 10-15% on average! :)

If this applies to the Clio too (no reason why not as both engines are very similar in design), then I'll be looking at having the same power as before, but with the need for cams.

And the best bit... £835+VAT for the full kit as opposed to £1147+VAT and ancillarys (yet more £££) and no inlet manifold match.

does this give more room in front of them? i.e. so one doesn't have to drop the rad maybe?

got any pics?

[AndyFielder]

ey, sound good mate!

Pics, more info, where can we buy em?

Mite look to get these over the jenveys for the new hybrid!

[midge]

iirc only avalable for f4r

[white16valver]

*possibly dumb questions* lol

Why do they give more power? Just shorter airways to the chambers, therefore less restrictions?

Won't increasing power that much on standard internals be a risk??

[AndyFielder]

would they not fir a megane head?

[stan]

They dont have a spindle for the throttle plate.

Plus they have probably developed a better taper and plate position.

[matty w]

i think they do them for the megane head

[AndyFielder]

stans looking into it for me.

Here's the blurb from AT Power

Currently the range is:

Ford Duratec DTH 38mm
DCOE 38, 40, 42 45, 48mm, 35mm long
Renault F4 41mm
Renault F7 41mm
Fiat 1800 41mm
Hayabusa (for Radical) dia 41 conventional throttles
Hayabusa 42mm
Ford Sigma 38mm
Honda F20 , K20 is being designed
FF1600 55mm Single
Subaru 72mm Single
Ford V6 65mm Single
(singles use conventional spindle design)

Tech specs:
Billet machined 6082 aluminium housings
Hard anodised 7075 aluminium shafts
Stainless steel hi-flow aerodynamic blades
Patented* shaft-less blade technology (*worldwide patents applied for)
Stainless steel integral linkages
Billet machined 6082 aluminium quick fit spin-on ram pipes
Fully assembled, balanced and tested, ready to fit
Direct-to-head, oval bores allow close coupled throttles for ultra sharp response
Ultra short housings for minimum packaging space and maximum ram pipe flexibility


With Direct reference to the Renault kits, we will shortly have a full turn key kit available with loom, ECU and fitting hardware. These will be available for sale direct or fitting in our workshops.

The shaftless design and inlet shape offers amazing throttle response and part throttle response and improves airflow by 7% over the competition

white16valver - yes, they give more power and should be absolutely fine on a stock engine. My Jenveys were fine on a stock 172 engine and it's done 45k+ with bodies and no bottom end or top end mods.

AndyFielder - they are only for the Megane head, I'm not sure if there are plans for ones to fit the Williams one, but tbh I cant see there being, not much point with the ports the way they are.

[AndyFielder]

sounds good to me.

what management would they be using?

[J o n]

can use any stand alone capable of running them, but for safety reasons I'd personally only use an Omex or Motec as these are the only 2 E-marked ECU's on the market. There's due to be a crackdown on cars without them, as technically it's illegal not to have one, but people can look into that themselves as a lot of people wont really care and go with a cheaper option anyway.

As they are the above is just the price for the complete ITB kit without management, same as you'd get from Jenvey basically... only far cheaper, better looking and better output.

[AndyFielder]

bit annoying you have to wait 5 weeks for the parts to be made up!

Will go for KMS as its a good price and the car is going to be used on road very little.

Andy

[AndyFielder]

where you getting the prices from buddy?

[J o n]

not sure on assembly time tbh, I dont think they are 5 weeks, if so I'd imagine that's only at the moment and wont remain the case lol

prices I'm getting direct from the horses mouth fella. All F series engines are £835+VAT

[AndyFielder]

ok, who do i contact if i want to buy a set?

[J o n]

Andy at GDI, they are the authorised distributor of them as AT Power dont/wont sell them direct.

Worth asking about group buy discount if they can/will do it, but I'm unsure as iirc the price is under what they should retail at anyway...

[AndyFielder]

anyone up for a group buy?!

[J o n]

meeee! lol

I'm getting some, mine are on order as we speak... in bright pink :lol:

[AndyFielder]

im planning on getting mine in bare aluminium, dont like the blue all that much!

[AndyFielder]

will be eagerly waiting to see what urs look like tho :D

[Taylor]

get in pink!! (anyone tell whos idea that was?)

[Chris n`nic]

This looks superb but it will be a while before I can get some cash together for it..how much would you reckon all in Jon?

Cheers

Chris

[J o n]

worth saving for mate, I've been to see where they are made and spoken to the creators and they are extremely confident in them... but then they are a massive success on the Zetec and Duratecs.

Not sure how much it would be all in, just over £3k at a guess with the bodies, cable conversion, omex, loom, sensors, install and labour charges. Worth adding cams to the cost imo, I think I'd have seen a genuine 240bhp with the cams I had in (428's) and these bad boys.

I'll be testing the first set, so you can come have a go of them when I get them fella.

[Chris n`nic]

Will do fella...looking at a new house at the mo but its not like I'm ever going to sell the cup so I can wait for a bit :)

Chris

[MattyH16valver]

mmmm....very tempting.. :lol:

[Matty86]

what power are you going for?

my F4R has just been rebuilt, so should hopefully be alright with something like this in the future! :D
