Anyone care to comment? I have read a few posts from people who have run them. I saw that malone ran one on his franken with good results. Anyone else? Does anyone have flow numbers that show improvement? Are the runner I.D's bigger than the stock 1.6td's I.D?

how much is the ATP manifold? 935racer has a sweet tubular pulsed manifold. equal length = equal EGT's across all four cylinders, and faster spool up. i'd say worth the money!

yes, indeed that would be sweetness. I remember Dave quoating around $900 for the tubular. I found a nearly new ATP 8V I can pick up for about 150.00. They are supposed to flow more than stock, and be a drop in fit, no fire wall contact. They retail for about 275.00

ATP appears to have a good rep. Comments?

It might be hard to fit a 3" DP because the turbo sits lower which mean the first radius will be much closer to the o2o shift linkage, not positive on it though I haven't done it to date.

The ATP manifold isn't exactly a drop in unless you have a turbo with a Ford/Saab style T3 flange.

I stand corrected, Drop in for a non vw t3 turbo.

Do these flow more than stock?

Dave did you do the setup on malones car?

In all honesty it doesn't look that much better than the one fitted on our TD engines. I'd save the $$$ for something else.

yeah i agree, i think the only advantage is that you then have the option to run other turbos, but you'd need all new plumbing and stuff, so unless your upgrading your turbo or using a gas intake manifold there isn't much of a point of using it.

WE used a ATP manifold that had a t25 flange welded on, same kind of thing, it will flow better than the stock unit no doubt, no a hell of a lot better but better.

Mike what do you mean by saab/ford style flange? Different than a standard T3 flange? It sure looks normal from the picture.

This type of cast manifold, there are several of them for sale on ebay and not too expensive.

I have seen that one before. I asked how long they would warranty the manifold. 30 days only. Not very long.

I just thought the ATP manifold would be a good upgrade. If the down pipe does not fit, and the turbo oil lines need to be changed, it may not be worth it. It was just a thought.
I have a 1.6TD exhaust manifold on the way to Passenger to get fitted up to a 1.9 head that is going to be ported. Just thought the ATP might give a bit extra flow.

I am going to be putting on the Merc 300TD Garrett T-3. I am also getting one of Daves modified intake manifolds. The merc turbo will not fit on our vw manifold unless a adapter is used. I think it will bolt onto the ATP. If I cant use the 3" DP though , I might as well stay with the vw manifold and just go with an adapter.

iirc, only vw came with the trapezoidal pattern, while saab/merc used the pictured rectangle shape

the chance that the pp down pipe is going to work with this manifold is extremely slim. its pretty much not going to work with out modifications.

foxracer1 · « **Reply #14 on:** September 03, 2007, 08:07:54 am »

subsonic if your going to run that merc turbo i would just go ahead and use the ATP manifold. I think it looks much better than the factory one more so if you have to make an adapter. Dave may be able to tell you if his DP would work. I wouldn't think it would be that different. And maybe you could send it to him and have him modify it for you.

Just my .02
