Diffrence : Inline/Parallel

[Waste Land]

...Excuse me for noob question. Whats the diffrence in Parallel and Inline carb manifolds. My cousin is looking at the Pro-Tec 650 manifold to put on my old 38s on his SJ and .....we dont know the diff.

Can someone explain quickly?

I believe the inline uses a coupler between the shafts and the parallel the carbs sit sideways and use a linkage.

hmm...never seen parallel before......pic?

 

[demolition_x]

then i have seen them that there are couplers connecting the shafts

ok. The inline manifold does use a coupler and the carbs are mounted with the shafts end to end running front to back. The parallel design mounts the carbureters with the shafts parallel with each other and crossways in the hull connected with linkage.

Performance wise the inline mounting may experience some lean hesitation in extreme hard right hand turns pulling lots of g force. What happens is that the force of the turn momentarily pulls the fuel to the left side away from the throat and will cause the engine to hesitate.

I am using a set of Full Spectrum carbureters mounted inline. All I do is freeride and freestyle and have experienced absolutely no fuel delivery problems in my boat. All the freeride people I know are using the inline setup.

If you are racing and are VERY good you might consider the parallel manifold.

If Get this manifold will the bolt pattern match up b/c as you more than likely know that the 38's off of a 97 SJ the flange is cocked at like a 30 degree aganst each other instead of all four studs in a line

If its for 38s.....it will fit 38s
