Dbilas Throttle Bodies

[CA Automotive UK]

hi to all

just to say we have started carrying Dbilas individual throttle bodies for BMW and other cars.
As example , we have seen + 20 bhp o M50 325 and 100% or more increase in throttle response .

Will also amplify any other mods such as intake , exhaust , cams etc .

please see http://www.ca-automotive.co.uk/dbilas-injector-systems.shtml

we are puuting a set on Giles ( BUT) 325 , then turbo charging the f ...ker witth aa stage 1 kit ....cant wait !!

100% or more increase in throttle response
How do you measure throttle response? I wasn't aware you could measure it quantitatively. :confused:

Shuriken.

[Chaos]

Is that like quantifiably? :p LOL sorry m8, couldn't resist. :D

As I understand it, you measure the time (usually in ms) from opening the throttle fully to actually starting to accelerate. That said, it's often just as easy (and more easily translated) to measure it with Doctor Nick's patented bum-dyno ;).

[CA Automotive UK]

well , you learn something each day ...I did not know there actually was a defined way of measuring throttle response , my comment was as you say more seat of the bum telemetry :)

nuting for my auto 325 m54 :(

[CA Automotive UK]

sorry Ernest , nothing M54 yet ....we will keep asking

[Shuriken]

Yeah, I thought it was more seat-of-your-pants kinda stuff.

Thanks anyway :)

Shuriken.

ps. Different words, same thing...quit your moaning :p

I was thinking of getting this set up for my 318is, I wrote of to the company a few times, as I was going to drive over to germany to get em fitted, but have gone off the idea....up to now...any way!

just a quick one mate, whats your price to have them fitted , that aint a bad price above inc the vat!

it states thats its about a 15bhp-12kp increase, is this likely for my m42 (RR @142.4bhp at Bexleys last month), I am interested to learn more about this mod!

just one other thing, are they only in Red, also can you adapt other filter(pods) on to the Dbilas airbox?

many thanx

HI SONNY

I would expect at least 15 - bhp with these TB's .
we are fitting a set to M44 next week so will let you know how it goes . Customer is then going to adapt and fit a turbo kit we supplied him !!

he is aiming for 220 - 250 bhp !
regarding installation , again I will confirm after we do thi sfirst one , but i am guessing around 6 hrsinc set up ....so around £280 install nett

[lee330sport]

On a 318is i see no reason why you should not be able to get it upto 200bhp in NA state with cams/exhaust/throttle bodies etc. The gains shown seem a little on the low side.:confused: But you will get that all important intoxicating intake howl.:D

[RDG 40]

sounds like an idea 200bhp out my 318 that would be good

hiya mate, well it sounds interesting, im also realistic in the performance gains aswell, 15-20bhp would be awsome, but on my 105k 12 rear old car I would be impressed with 8-10bhp!

also iv only seen them in Red on the 4 pots and Blue on the six pots, do they come in black?

well when im back in the UK I will give you guys a ring to further or conversation!
many thanx

[sonny.j.h]

Just one other thing mate, it states that it comes with its own air box, in the pic, It seemd that it would attach to the MAF?

so im asuming that MAF is still retained, as this is the most restrictive part of the M42 (later M44 had a better desinged one), is there a alternative way of bypassing this? I know that there is a Alpha ignition set and a Uni-chip set up, but my kwnoledge of this is very limited!

sonny

[CA Automotive UK]

I will check on the red / blue issue .

Yes the MAF is retained , so the car still runs smoothly at all revs .

thanks

[sonny.j.h]

OK good stuff mate!

so do you do a mod or convertion kit toexclude the MAF, or would you say it wont be worth it?

[lee330sport]

I your serious on using Tb's id go for a decent management system, DTA or emerald etc and get rid of the MAF for bigger gains.

[sonny.j.h]

well iv looked into all route Lee, on conveting my e36 318is!

supercharger, turbo, 2.0 ltr upgrade, New manegment system, Throttle bodie ect ect.....even a new car (M3 ..lol)

I work out of the country, so my 318is is my week end project car, Iv had it 3 years now and im not planning to get rid of it tillate next year, to make way for a 330ci, but in the mean timeI just want to have fun with it!

the throttle boddies are a cheap alternative to fun, i.e the noise the TBs makes is awsome (asuming the Dbilas ones sound like the webber/dellarto ones)

the 318is is a awsome engine, its already twaked as it is by BMW so its hard to extract any more power from it!

the mods im currently have on my B18 M42 i as follows

gruppeM induction kit (replica)
Chip
bored out throttle body
cat back exhaust

[lee330sport]

I disagree about the extracting more power part. Anything is possible if thought about properly. But the the MAF NEEDs to be removed. A set of cams, new management and throttle bodies would put you at a minimum of 170-180bhp when properly mapped. 200 would need headwork.

And yes you cant beat the sound, although the diblas system still uses a single intake point instead of utilising the separate intake barrels of the TB's. So you will not get the same weber induction roar.

[sonny.j.h]

so the Dbilas use one intake, so if you removed the MAF you could utilise the 4 ports (im asuming it has 4 seprate butter-fly valves) instead of the one?

yea I agree with you mate about the increase in power, but thats major head work, my friend has managed to squeez about 210 out of his 318is, he does have a Eaton blower though!

well im interested to see the out come of the lads on here, when they give the M44 a going over woth the Dbilas kit!

p.s your right Lee about any things possible....but at a price :eek:

btw im loving your car dude, fcuking loving the face lift e46..awsome

[lee330sport]

Yeah the diblas uses the single intake then the 4 separate butterflies so can only be a restriction in my view. The only time you really need a plenum coverin gthe barrels is when your using Forced induction at the same time.

Bennyboy lies next door to me and has a 318is. maybe i can convince him to run some throttle bodies:D

Cheers for the comments too.[ok

[CA Automotive UK]

not to caUse an issue here ....but you dont necessarily need to remove the MAF to get good power ....and removing it may in some cases lead to poor low speed performance.

I am only sure about this because I have, last week, had several long discussions with two suppliers of CSL style airboxes tHat retain the MAF and still give 25 - 30 bhp gain apparently .
We have also been in consultation on all this with the car owner who just happens to be ..wait for it ...a senior lecturer of mechanical engineering at city university who does nothing all day but develop engines for Merc and BMW !!! He currently has a 440 bhp BMW 330 diesel engine on his bench dyno and has invited us up to see it . How far up this particular customers tailpipe do I want to insert myself ..? ALL THE WAY [hiya

Ultimately though Lee is correct in that for MAX POSSIBLE power the MAF is a restriction
