Hey fellas wanna know a little feedback and some help choosing which header to use on my fully built 83mm gsr motor with a s366 .83a/r Now i know they may be a related thread like this but i would like to see what most of u builders and tuners do you see fit to use from your personal experience and if u would like to direct me to thread related sites or send me set up with the use of the inline pro header.And yes i know both are proven,this is y im in such a dilemma.Please your feedbacks will be well respected.Thank you.

 

I know the Inline Pro probably flows better than a typical log manifold, but this thread has an old comparison between a log and a Full Race ramhorn style manifold:

It's not exactly what you're looking for, but it's an interesting look at the difference between a short/unequal-length runner manifold and a longer/equal-length runner manifold.

 

Matt Keller ran mid 9's @ 160ish on a Inline PRO T4 manifold.






I have the InlinePRO T3 SS Manifold on my car and i cant complain. a/c p/s and 450whp daily.

 

^^ so simple but so sexy

 

The inline pro is the only 'log-style' manifold I will ever run. The runner placement as well as wastegate placement is optimal in order to flow smoothly (reduced turbulence) and sample boost pressure with all 4 cylinders opposed to 1 or 2 like some log-styles are.

We just finished a customers B series set-up last week using the Inline Pro t3 manifold.





I also have some data comparing identical set-ups with the inline pro vs a ram-horn style on a built B20 we did a few years ago. I'll have to pull that off the dyno computer and post them up if I get some time though so you guys can see real world data. You'll see significant gains with the ramhorn style up top though. Search though... this has been covered a billion times.

 

agreed w/precision

 

ok so far im appreciating thae feed back im receiving and it look so far like the inline pro header is in the lead,so keep the comment or feedback coming or can i see some graphs with the 2 headers in comparison.Thank you.

 

Also that thread with the test between that other log style manifold is a poor test because the inline pro outperforms that contraption of that poorly developed manifold,plus if u examine the inline pro properly u can see that the inline pro aint really a log style it comes down as header type,so this is y if any one has any vid or other info with just these 2 specific manifolds it will be very helpful

 

Dude, you are still going to get more power from a manifold with a long collector v. a Inline pro. Just look at the two and it should be common knowledge.
