Towing twins
« on: December 01, 2009, 02:58:56 PM »
Here is a set of twins and manifold I built over this last weekend. It is a GT35R over an S366. Still have to finish the cold pipe, and pipe to intercooler. No shots during fab, and no good shots of the manifold, but it looks just like the last one I did.





I know you will all love that I cheeped out and just did pie cuts on the hot pipe.  O0





I will try to take some more pics next weekend, or whenever we actually get around to installing them.

Yeah it started life as a big CLR, and I needed a tight CLR. Lazy pie cuts ensued.

Eventually, but first we need to find a cracked 53 block to replace this as a mock up motor first.

I have a mockup head, just need to find a block, that motor is a good running 24v, need to get something that is just a block and head.

Your post actually made me LOL to the point that my co-workers were looking at me funny. Yeah with the poor flowing heads, especially the 12v's we need the pressure ratio's of "boost while you boost" to move enough air to make any sort of decent power.

The hott pipe is the only part needed to do something like this?????

That would be badass to have a compound turbo set up on a honda....

Dumb?  But small turbo on top of big turbo????  Right!

The cold pipe is sort of pictured, we were just missing the coupling boot. So you need a hot pipe and a cold pipe, for compounds.

Not sure what the point on a honda would be, other then the I don't think it has been done factor. High PR and low flow is exactly the opposite of what a honda needs.

That setup is probably good for ~75lbs/min at 50-55psi. Where as the bottom charger all by its self is good for 82-85lbs/min at ~35-40psi

The last picture is the most complete shows the: Hot pipe, cold pipe and down pipe. The secondary turbo's (small turbo) outlet goes to the intercooler, the air filter goes on the primary (big turbo)

Looks killer. Please keep this updated. I'm really wanting to know how the tuning goes with the twins and p-pump. I'm building something close to yours for my f350.

This particular set of twins is going on an 01 24v Dodge. It is the test mule, it has had about 5 different twin sets, and at least that many singles too.

The P-pump truck is going to be a little less street friendly.

What about the tuning are you wanting to know? I have done a couple twin sets for p-pump trucks already.
