Why would you want a Tickford head, for performance?
Best thing about it is the T on the front lol. Don't forget the T made an extra 8 kw over std, that included cyl head, camshaft, exhaust, ecu and not to mention that extra fuel pressure. So out of those 8 kw how much do you think the head alone gave it? At a guess i'd say 1 or 2 kw at best. |

f**k Paul... All you do is bag these engines... I'm willing to bet that when these things first came out you and alot of other people would have given their left testicle to own one of these cars.
Look at bombers... 15.2 quarter stock. Most of them would do at least 15.5. Whats that, about a second or more off a normal I6. These things rev cleanly to the redline. Their torque curve looks like ayres rock, not the gentle slope of the normal I6. The extra torque makes towing 50x better, and their top end kicks a** over the normal I6. Yes, any standard I6 can do this by adding a cam. But stick a cam in a tickford motor and once again your ahead in performance. Head, cam, fuel pressure, etc.. Its all a package. But then again, there are aparently gains to be had with an XR head and cam, but using the standard fuel reg. So, those extra couple of kw do make a fair difference. Tickford obviously did somethng right with these heads, and the proof is in the pudding. But its not the extra few kw, its the availability of torque across the range that the standard I6 doesnt have... Pheww... end rant and wait for reply... |

OK, dont mean to go off on a tangent...
But why the extra fuel pressure for the XR6? I've seen all late model fords - V8's, tickford 6s, stock 6's.... all gain at least 5kw on the dyno by reducing the fuel pressure.... why the need for increased pressure for the XR6? BTW i dont think paul was baggin the tickford engine - just paying that much for the head alone when really, it was a performance package.... including ECU etc.

Nah... Paul was paying out on it, as he always does... You get used to it after a while...
I think the higher pressure reg is to prevent the mixture from leaning out at higer revs. Changing the pressure will lean out the mixture, but maybe too much and will cause detonation. While the extra power would be nice on a dyno figure, its not nice at the cost of a piston or 2. Its obvious Ford errs to richer is better... Worst that can happen is to kill a cat.. Easy, cheap fix. But if you loose a piston or 2, thats an expensive fix.. Or at least thats how I see it. |

My ED XR6 certainly runs rich, but it still makes 116rwkw with only extractors and exhaust done.

Yep i do bag them out, and the "Tickford" engine is the same as a stock engine, it's the head and other add ons which change it.
And why have i bagged them out? I throw a $120 cam in my car only to rip an EL XR6 by 3 car lengths... and that was 3 runs, i'd say part of it was his driving, but he even said to me that up top he couldn't get near me, i kept hauling away. Now i am talking EF and EL series mainly, the AU XR seems to go very well in comparison, don't know what it is as i haven't bothered looking into it.... weight maybe? I have heard the AU was lighter but don't know the difference between that and the EF. I'll say what i have said before, best thing Tickford ever done was fit the 3.45 rear end, and also the twin headlight front. But in saying all of that, i know they could have opened them up more and got them going, but they have to comply with emissions which makes it extremely hard. |

i'd rather do a cam change over a tickford head, more BFYB!

I agree Paul... As I said, throw a $120 cam into a standard I6 and it will make it go...
But put that same $120 cam into the XR engine, and your back to where you started, being a couple of car lengths behind in a race. I believe 2 of our members here proved that.. One with a Fairlane, the other with an EF Ghia. Put the wade into the Fairlane, it became a winner. Put the same cam into the Ghia, its back to being the winner... Ford could have done alot more with these heads, but when you have to consider development costs, emissions, warranty and servicing their hands are usually pretty tied... |

dosen't most of the power advantage on the xr6 motor come from the cam?

Nah it's everything combined, it's camshaft is slightly bigger than std and the Wade and Crow stage 2's are larger than the XR.

Yep that ones definately a faker (the one with the texta T wings)
 All i can say is that some of the Tickford 6's kick a** over the normal I6 i have had mine dyno'd and got a very pleasing result as it was stock as a rock at the time.
(during the E-series dyno day). I bet quite a few other cars 6cyl and 8cyl. Modded and unmodded too, not bad if you ask me. Also a mate of mine has the normal I6 has just upgraded the exhaust system and added extractors and hes driven mine and still think it would beat his ford easy. So yeah just my 2 cents, the Tickford engines cant be all that bad.

yeah but you forget about the 3.45 LSD, that helps a bit with put you in your seat!

A mate of mine called Magoo who was on here in early days has an EL XR6, when he bought it the only thing missing was the 3.45, it had a 3.08 in it and was a bag of s**t till he threw in the 3.45.
But then there are freak engines out there, and there are also slugs. |
