Here are some pics of a log manifold setup i am making for someone. He will be running a forged shortblock with stock heads/cam for now and TH400 combo. Here are some specs and progress pics:

1.75" primaries
2.5" pas. manifold with 2.5" crossover
44mm Tial style wastegate
3" main log
3" DP

Mild steel mig welded

 

Looking good. I tried to get a set of shorties to fit on my setup and finally got sick of it, went with a log style setup. Seemed much easier that way and I doubt I will lose any power, turbos are too small either way.

 

Thanks dude. So are you running twin turbos or single? If you are running twins, then the logs wont slow you down.

 

hummmm looks familure......

 

Twins

 

slow poke... hurry up.

 

Realquick, I think you need to try and fit a 3.5" downpipe and let me know how it turns out.

 

Mike, with the stock k-member on the mockup, there is no way it would fit IMO. Now, I have a tubular k in my car and took some measurements... looks like a 4" would fit

 

Looks like fitting it past the steering turnbuckle would be my first issue, then fitting it between the crossover pipe and the frame rail is the second. And that's on a 3.5". . .

Stock or aftermarket K?

 

BMR aftermarket.

 

only like 4 months man and il be home.... should have the car up by he beginning of march unless i chance my MOS (job) to blackhawk mechanic, il find out on the 13th.

 

Mine fits with the downpipe passing through the same area. Mine has a tubular K-member, though.

Do you think a 3.5" would fit through there if you ovalized it?

 

not sure...
