    Wolseley 6/90 revival

    Hi All, front chassis final fitting and welding complete, getting paint on now. Inside the car wiring is all done and ECU mounted. Next stage is to powder coat engine/trans mounts, complete the underseal of the body, run under-car brake/fuel/power lines, then put the engine/box back in...

    Modern-day Miura

    Hi Joel, yep agreed! I think folks lose track of the fact that the length is related to a single RPM point where peak torque is expected, and that having a bit of variation (i.e. a few inches either side of "ideal") simply spreads out the torque peak a bit. I think any bundle of pipes with...

    I reckon that length would be fine if you took the normal care to separate leads and avoid close contact with potential earths

    If so cool. I ripped the input shaft out of the TH400 I had in my previous track car and sent the guts of all the lifters into the sump on a mega over-rev Exactly the kind of shrapnel that would demo the oil pump!

    Looks great Andy. Are you going to put trash screens in the scavenge lines to the pump? Cheers, Andrew

    Hi Andy, looks great. The front plate photo prompted a thought based on a near catastrophic failure I had. The grub screws on my oil pump pulley were tight but the pulley walked forward in competition to the extent that only 1/3 of the belt width was engaged on it. I only noticed by...

    Hi Leon, Stuck it directly on. Lined pretty much the entire engine compartment. Cheers, Andrew

    McLaren M1B replica on the track

    Hi Markus, I have a 5mm aluminium base-plate located by a pair of long bolts with crush tubes on each side of the hilborn manifold. The base was waterjet cut so that the stacks would go neatly through it and into the hilborn clamps. Under the baseplate there are also sleeve/spacer tubes and...

    Hi Leon, I had a similar concern. I used Ados F38 to glue heat reflective foil over the underside of the rear clip and put slots above the headers as shown in the photo. Nothing has caught fire yet. Cheers, Andrew

    Awesome Leon!! Fantastic milestone and I bet that has given you a real shot in the arm to drive through the bug list. Cheers, Andrew

    Hi Andy, headers look superb. The V-band collection looks ideally placed for a muffled tail section if you ever get pinged by the noise police. great stuff. Cheers, Andrew

    Air leaks with slip fit collectors and EFI causing rich A/F?

    Hi Joel, My joint area is definitely pretty leaky as you can see - the lugs on the collectors are OEM but are not used as both the engine and the back section of the exhaust (mufflers etc) are completely solid mounted to the frame. I should also have clarified that I run in open loop until...

    Air leaks with slip fit collectors and EFI causing rich A/F?

    Hi Joel, Obviously every case is different but in my case, using the "single" slip fit collector in the picture below, I had to abandon the use of the O2 bungs you can see in the collectors, and install a new bung in one of the primary pipes about 12 inches from the end to avoid air sucked in...

    Hi Leon, no I'm still diverted onto the resto-mod of the 6/90. Hope to be racing again in '22. Good luck with the shakedown session - let us know how it goes. Cheers, Andrew

    Andy, it knocks a lot of sound out - it's basically a deep rumble/roar rather than a sharp bark, typical of the flowmaster single chamber sound - probably nearly as much racket coming from the 8-stack. Never had a noise problem with stewards. Cheers, Andrew

    Hi Andy, my approach probably won't work for you, and you look well advanced on some great pipework. Pic attached of how I did it. Cheers

    Hi Andy, looks awesome as usual. Are primaries a bit long - 34'ish would be nearer a conventional calculation? Or are you constrained with packaging? Cheers, Andrew
