MG TD TF 1500 - Velocity stacks on my TF

Just got my new velocity stacks for my TF along with custom fabricated air filter screens that do not detract from the air flow of the horns. I like the increased induction bark and the ability to adjust the carbs/check mixture with out having to pull the vokes filters off (a total pain in the tail). Plus, the idea that it might go faster ;-)

Looking really good Alex. Impressed. Who did these for you?

Alex please contact me at beemers2up at yahoo dot com.

Hi Alex, I would like to know about those too. I have a Leystall Lucas cylinder head installed which is 0.5 inches wider than the standard head and the standard filter arrangement cannot be fitted.

Thanks,

I got my set from Manley Ford who races a competition TD. Along with the velocity stacks, he also has a bunch of other great T series performance parts (his Headders / extractors are georgous). He can be reached at manley776 at yahoo dot com

Alex,

The intakes you have are strictly for racing. Also, you have very limited filtering, and a small stone can damage your carburettor or even the inside of the engine.

Airflow into the manifold must be stabilized and with minimal turbulance for good torque at low revs. A short intake does nothing to straighten out the airflow and so it requires high RPM to straighten them to develop torque.

The longer the intake, the better the low-end torque. Shorter intakes such as you have, restrict the development of torque to a higher band.

Have a look at a recent Mustang V8 manifold, and you will see that the intakes cross over the complete top side of the motor. In fact, that is true of most modern V8s as the development of torque for every-day use, is preferrable at low and mid revs. You can't always see them on today's car, hence the Mustang example.

Some hot rods (I subscribe to Street Rod) will display tall "velocity stacks". and that of course, is to develop low RPM torque.

I'm attaching a pic of the intakes I use on my TF. If I had more space like a TD, I'd have longer intake tubes, as I prefer my torque at lower revs.

Alex,

Sorry, I just re-read your post and realize you do ineed. have filtering, but the comments re short vs long intake tubes, still apply.

Gordon,

I'm with you on the short vs long, but like you say the clearance is very minimal for the TF, thus I had to have short stacks. All that said, I had NO stack from the previous pancake filters thus, it would seem to me that this is better than the orriginal set up. Am I wrong in this assumption?

The filters I have are three layers of stainless cloth and mesh. The inner and outter layer are at a diagonal to each other. Inbetween the two is a MUCH smaller weave that is not visible in the picture. Since the covers are bespoke (made to fit), you could have a set made for your stacks.

Where did you get your stacks? Do you have an additional air filter that you install beyond the rock guard you have welded to the outside of the horn?

I believe that I bought of Gordon's style from Abingdon Spares about 15 years ago. Hadn't yet found an OEM style air cleaner for Lazarus. Think I still have them somewhere. Bud

They still have them - Page 67 #60 (1.25) or #61 (1.5)

Now, if you want your TF to really get up an go, try a set of Manley's exhaust extractors.

For $700 you also get a work of art!

.... and if you do indeed, get a set of those stacks, be sure to check the inside of them. I found them quite rough inside, and took some 400 sand paper to clean them up.

... and be sure to use a paper gasket, just to discourage leakage.

Do the abingdon spares ones fit between front carb and the bonnet side on a TF? I looked at mine again and with the air cleaner on there, there isn't much clearance left with the way short ones I have.

Gordon, His extractor is on the list. Not likey this season though. Any idea on a 2" muffler that would be free flow to go with his extractor?

Alex
ABW Waugh

Mine do, Alex.

They are off the car right now as I am cleaning the carbs, but they certainly fit, but of course, expect to get bloody knuckles, fitting them, especially the front one.

As for a stainless muffler ... well that has been the subject of as lot of thought. I'm not installing a stainless system untill I can find one with stainless wool as a baffle medium. Even the best stainless systems. and Falcon comes to mind, use glass-fibre "stuffing" to muffle the sound and even that gets blown out after a while. I recall at least two entries on this BB to that effect.

In an ideal world, a stainless system should be ALL STAINLESS. and not just the tubing. There are several custom manufacturers of (just) stainless muffles that will make one to order, and they're not that expensive, considering that the muffler will outlive you.
