Pre-planning for twins/ sled pulling season

[9312v]

So I have a bit of money set back right now thats burning a hole in my pocket. Today at work I was thinking either a cam, or a exhaust manifold. Plan is to get a s475 paired with the super bee(57/65/14) that's currently on the truck. I also have a PS intercooler and 3" piping sitting around waiting on boots, clamps, and to be installed.

Now which of those two would you recommend and what brand's would you recommend? If neither of those, what would you get that is in the same price range as those both?

I'd pair the Super B with an S472 w/1.10 housing... it'll run better and cooler with a ve pump. We have a narrow rpm window.

You'll have more gain with a cam over a manifold... but they are not comaprable in price. A cam requires new tappets, and little odds and ends that run the price up around $800-1000. A manifold will run $450-650 range.


IMO - if you plan on sled pulling and running twins.. that money would be better going towards a larger/better set of injectors to REALLY wake those twins up. DDP stage 2 injectors are a 50lpm injector (20% larger than stock)

Twins are cool but will probably put you in a pulling class you can't compete in.

Brush pullers to the front! If you stay low key, you can swing it. Most brush pull "street" classes consist of Danville-turbo'd Duramaxes and Fleece-turbo'd Common Rails. Stock, my azz! Who is going to suspect a 1st gen?

If you want guaranteed completion though, I'd lean towards a Holset-appearing single. With twins you stand a chance of being pushed into Exhibition eventually and there's not any competition there.

yeah.. around here non of the truck classes allow twins. unless they run a combo class that as long as you weigh 8500lbs you can run.. truck, tractor, modified, etc. etc.

Just check your rules. those rules might only be in this area.

Go with the cam, it will help the s400 spool.

There are places that don't check or care what turbo you run. Built whatever you want somewhere will let it pull.
