matt_lamb_160 252 Posted September 17, 2017 Yeah they are odd. 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites
slydog 7,873 Posted September 19, 2017 They need camshaft,compression and ignition for big carbs but after that cyl head flow. No point putting a tiny port dirt slinger head on a engine you want to rev over 7000 cos It won't make power. Been there,seen it,done it fixed it. Turning the carb East West doe's enhance em though but many choose to stay North/South and it's all but free hp ??? 2 Valvebouncer and CHESTNUTXE reacted to this Share this post Link to post Share on other sites
CHESTNUTXE 7,312 Posted September 19, 2017 i wanted ask this if fitting east west can you use the 6cyl throttle cable or upgrade to a v8 longer one Share this post Link to post Share on other sites
ando76 4,354 Posted September 19, 2017 There are definitely gains to be had from turning the carb east west and to answer your question, you can use the std 6 cylinder cable when you convert to east west. 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites
CHESTNUTXE 7,312 Posted September 19, 2017 i was reading somewhere that the later xf crossflow utes 92 93 used ea falcon style cable ,does this affect anything ? just looks like a std crossflow cable to me on the ute, Share this post Link to post Share on other sites

CHESTNUTXE 7,312 Posted September 19, 2017 yeo that rings bells dean ,xg one all the way to the throttle body Share this post Link to post Share on other sites
ando76 4,354 Posted September 19, 2017 The later Utes used the pedal with the in built throttle stop, a good thing by the way. They also located the cable on the end of the bracket, rather than the firewall. This is also a good thing as it leads to better cable routing. The side benefit of the use of the xg/xh cable is also a win. 2 CHESTNUTXE and XTREME KARTS XF reacted to this Share this post Link to post Share on other sites

I daresay the change occurred in 88 when XF sedan/wagon stopped and EA started. 2 CHESTNUTXE and XTREME KARTS XF reacted to this Share this post Link to post Share on other sites
XTREME KARTS XF 1,212 Posted September 19, 2017 What @Mr Polson and @ando76 said. EA accel pedal will be also fitted. Cable wont be bolted to the firewall like on eariler cars, has a sqaure end where it clips into the pedal base. 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites
CHESTNUTXE 7,312 Posted September 19, 2017 does anyone no exactly how tall an air cleaner will go on xf bonnet without mods,like 1 or 2inch ? the bloke at aussiespeed reckons you can run the carby on the manifold without a spacer to help,i usualy like a 1/2 inch spacer,but does it really matter ?

Mustardxf2 310 Posted September 19, 2017 Mine was hitting bonnet with no spacer and 2" airfilter Sent from my Pixel XL using Tapatalk 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites
slydog 7,873 Posted September 19, 2017 Doe's it really matter...yes it doe's is the short answer. If you use a filter top air cleaner and base no ellement it will clear with a 2" spacer and give the car best chance of using the carb combo. 2 Valvebouncer and Slow250XC reacted to this Share this post Link to post Share on other sites
CHESTNUTXE 7,312 Posted October 5, 2017 Question when instaling east west carby should the primarys be facing towards the tower or engine ?or it doenst matter cause its open ? Share this post Link to post Share on other sites
gerg 10,871 Posted October 5, 2017 Question when instaling east west carby should the primarys be facing towards the tower or engine ?or it doenst matter cause its open ?Not sure how yours is but some 4-barrel manifolds have half of the plenum jutting out and half joined to the runners. I'd put the secondaries closest to where the runners are, ie the easiest path. That way, at full throttle you get least restriction.Probably doesn't make any difference but sounds great in theory.A spacer would help too.Sent from my CPH1607 using Tapatalk 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites

slydog 7,873 Posted October 5, 2017 Deff 2" open space makes hp. Seen it so many times. Carby faces primaries to shock tower secondaries to engine and staggered jetting for consistency in response. 2 CHESTNUTXE and matt_lamb_160 reacted to this Share this post Link to post Share on other sites
CHESTNUTXE 7,312 Posted October 5, 2017 i wonder if fuel rail and accel bracket will clear everything ,im hoping so. Share this post Link to post Share on other sites
CHESTNUTXE 7,312 Posted October 25, 2017 i think i have a good carby in mind its a six50 holley HP alloy street d/p NO choke housing ect,seem quite popular or the normal HP race series in the gold colour. Share this post Link to post Share on other sites
CHESTNUTXE 7,312 Posted October 31, 2017 i wanted to buy a carby today and everybody is trying to talk me into a quickfuel carby ,they tell me a holley HP D/P SIX50 will need a ton of soughting out,as where the quickfuel wont and it is more of a hand built item than a mass production line carby ,they also make a 450 d/p but im really sold on a six hundred or six fifty.has anyone else had one of these quickfuel items .

deankxf 20,292 Posted October 31, 2017 sorting out a carby cant be as hard as converting to efi surely.. that said, My dyno tuner wanted me to run commodore efi management on My crossflow so he could tune it with kalmaker software 10yrs ago. i had GRA lpgas on it at the time . 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites
gerg 10,871 Posted October 31, 2017 Quickfuel have a lot of features that you have to pay top $ for in a Holley or buy lots of add-ons. As far as i understand, the QFT range can have changeable high and low speed air bleeds, possibly power valve channel restrictors, air emulsion jets and idle feed restrictors (might depend on what metering block they come with) and an air idle bypass (for lumpy cams). On a vac sec carby, the spring is a fixed rate and the adjustment is in the vacuum supply.They've basically taken Holley's modular approach and gone one step further.Sent from my CPH1607 using Tapatalk 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites
