H/c/I, intake and inject question.

That's not the correct way to do it. The system is meant to be sealed, and by having the tube running from the throttle body to the valve cover keeps it sealed. Some guys run the tube from the valve cover to the intake tube (after the meter) in cases where they're modifying as you are. A good CAI will have a boss on it so you can tap it for items like this vent.

I thought of that after I posted, will probably be what I do.

I hate to burst your bubble, but I sprayed a 175 dry shot for years on 19's(as have many others). You don't always need bigger, sometimes you just need better knowledge of how it all works.

Hmmm, well I just figured that adding the additional fuel in the tune and keeping the stock fp was far better than asking an injector meant to flow at 39 PSI to bump up to 70+#'s. I have the knowledge to do it the right way. The way I do it is the right way. I know guys that make 400+hp on 19# injectors and a 12:1 FMU, but that certianly doesn't make it the right way.

I'll run a breather filter if that's the case.

And that cam is fairly mild, it would probably pass emissions too.

218/226 .512/.512 112 LS

I think it will perform well. 218/228 .542/542 112 LSA. Emissions shouldn't be a concern when the car has no cats and most of Anderson's cams are not emissions passing cams.

I'd run it as it helps circulate crank case pressure. Only time I ever saw it blocked off is on FI set ups.

Current set up.

90mm lightning mass air. Just ordered.
4 inch Anderson power pipe, will be picking it up this week.
70mm accufab race TB ordering today.
24# injectors.

Still looking for an intake manifold.

What signicance does the vacuum tube on the a TB serve? It just vents to the valve cover right?

It's part of the crankcase ventilation, allowing in fresh meter air. Without proper crankcase ventilation you can easily start blowing oil by the seals.

The "virgin" part had no bearing on the conversation so I didn't see the need in adding it.

I just found it humorous they added that in.

So bigger it is! Actually I made a mistake. I personally run a 70mm Accufab Race tb on my vehicle. It's nice to have a full 4" pipe end to end. I see abolutely no harm in it at all. I also run 30# injectors with a stock 5.0 HO cam that has a stock idle and it drives exactly the same as it did with 19's. The only difference is that I can now spray a 125 dry shot if I want to and add fuel throught he tune. I have seen numersous threads about GT40P takeouts with a TFS Stg 1 cam, 1-3/4 or 1-7/8 longtubes, 3" exhaust, and a 70 or 75mm tb putting down 300+ to the tires. Restrict or time your airflow characteristics with the camshaft and open it up on the ends.

Now that you say that, I went to their site and looked them up. Says A-356 VIRGIN aluminum.

[Lone Sailor]

Are the Brodix heads steel?
