Single large TB info needed!

[J182sport]

As above im really intersted in people's views on this i have emailed GDI but i know they are busy so can't always reply,first il just get some info from anyone who can help i want to get a Single large throttle body setup.

seen i think a year back GDI's black 182 had this same setup im very interested in what i need for this and what kind of gains to expect? price is another,

if pos id like to keep the car on the standard ECU? its been remaped by jamsport along with inlet matching,

Any info on this would be so good as its something i want to do but not alot of info on it?

Pointless in my humble opinion. The standard throttle body (cable or DBW) is not a restriction, the standard inlet manifold is the restriction.

Fitting a larger throttle body will just give you effective WOT (simply put the point at which the flow capacity of the body exceeds the flow capacity of the inlet manifold/cylinder head) at a lower throttle opening i.e. at less pedal travel. This just means that a large % of your pedal travel is wasted and that effectively metering throttle inputs is more difficult.

The standard throttle body does not become a restriction until it is required to flow sufficient air mass for well past 240bhp.

If you wish to maintain the standard ECU then myself and AWT have a solution in the works, have a read of the last couple of pages of the "new super cup lump" thread.

the theory I would say is fairly sound (with a very obvious bias ) but in reality it just doesn't drive like that. However, it is a better mod to make on an engine that's had internal work done (raised compression, cams etc)

OK thanks for your advice il keep looking into other ways like cam's!

what cams would you say are the best? not too wild but good enough gains?

dont want to loose the way the car drives too much.

il read through the other posts

Cat Cams 428s work well. Give us a call at GDI if you want some options

 

[kevo66]

cat cams FTW TBH!!

 

[J182sport]

what car they like what sort of pwer gains can be had and is the car still a smooth drive everyday?

On mine?? Well I had the cams fitted and mapped and a matched inlet and saw 16BHP and a good dollop of torque all the way through!

Drivabilty is bang on, well it has a flatspot due to the decat but Paul has fixed alot of that!!

Assuming the engine is healthy then CAT428 cams along with a good remap will see circa 15bhp increase. Idle quality is pretty much as per standard and low speed driveability is unaffected, very low RPM torque is slightly reduced but the fact that the engine will pull cleanly for another 1000RPM over standard more than makes up for that. To give you some idea my 100,000 mile old 172 engine makes over 180bhp at 100RPM over the standard rev limit.

428's - can't go wrong with them IMHO.

They sound great! il be putting them on my list! thanks for the advice guys,

what sort of price am i looking to spend for the cams, and to be fitted will it need to be map'd? if so will the remap thats on the car be no use?

cheers again

unfortunately prices have gone up recently with the strength of the euro/weakness of the pound

send Icarus a PM, he can supply you with a set of Catcams 428's

or alternatively you can get a set of schricks from yozzasport

[J182sport]

I know iv just orderd a new set of OZ wheels and the prices have gone up and he said the price is about to rise again! coming direct from italy as iv orderd the new colour other companys can't get the OZ wheels from the uk supplyers now so the euro affects it, il get in touch with Icarus ,not looking right away but im getting prices and options now so i know what im looking for,was even looking at the Newman cams at jamsport whats people thoughts on them?,

Is the the £115 premium for the schrick cams over the Catcams worth it? i like the sound of the 428's above saying that i don't know much about any of the cams for the clio,

thanks

 

[Fred@BTM]

IMO yes, can't beat Schricks

 

[franx]

IMO yes, can't beat Schricks

Colombo & bariani cams will be the only ones proven to beat the german metal :evil:

Not kidding ; worth looking into

 

[TooneySonic]

/\/\/\ hehe i was wondering how long that would take lol

 

[franx]

btw; same price as Schrick ; only better .. Schrick has the name to be able to ask silly $$




Yeah TooneySonic; it was expected.. too bad no one on the island have started to try ; although Yozza was looking into things of starting to sell 'em there .

 

[Fred@BTM]

better than schrick? go on tell me more

 

[J182sport]

Ok,what are the difference between the schrick and Cat cams? in terms of the way they deliver? i liked the sound of the cats 428 above as it won't affect idle and alows a smooth drive when not on cam etc im looking for something i supose not too wild,

tell me more about the Colombo & bariani cams aswell Franx! also what did you pay for the cams deliverd?

thanks
J

 

[franx]

^ you need to find out where the Alfa Romeo boys get there tuning stuff from, They will be able to import/deliver ! These are the ones; with price listed

http://www.colombo-bariani.com/popup_dettaglio.php?lang=eng&id_prodotto=103

they got me around the 200 hp , well 172+ horses at the WHEELS.. never exactly known how much % is thrown in the equation. 15 % is used a lot. Torque is also awesome , smile on my face every time i go for a ride

I did the inlets aswell (Angelworks) , also a 182 exhaust manifold but do'nt know if that helped a lot. Just found it easier for the yearly MOT/cat change with this one on

 

[J182sport]

Thanks Franx for the link,they are going to be around the same price at the cat cams then the exchange rate is crap,by the sound of it they are a good option,out of interest what torque are you getting,did you get a before and after?

mine is runing jamsport matched inlets and remap to suit rolling road before and after its running 184bhp 165ft the car feels great,can't wait to get some cams now! its running standard filter and cat but with janspeed catback,so some more small gains to be had with a decat and GOOD filter setup! in the past i always had decat fitted and maxogen to my other cliosports

thanks

 

[franx]

Before; power is at the wheels . Top lines are torque, in Newton Meters

After ; also matched inlets like yours. Torque AND top-end improved
