Im boosting a GSR engine.
Will be removing the casting marks from the ports and running a Edelbrock intake.
I'm using a Garret T3/04E with 57 trim compressor and .63A/R turbine housing with 2.5" 4 bolt exit and will be aiming for 350-400whp.
Now manifold choice.
Id initially thought to use a log style, but being a fairly small turbo, will that move the power band down, meaning it would run out of puff top end?
So that would leave a choice between mini-ram or full ram.
What would you suggest?

Thanks

 

Go mini ram if you plan to grow in the future

Log if you're absolutely sure you want no more than 400whp

 

This^

I gained 50whp at the same boost level going from a log to a ramhorn (420 to 470)

 

Miniram gets my vote

 

Who makes some of the best minirams?

 

I do










Lol

 

I find this disturbing. It's not that cut and dry at all, sorry, fellas. But horribly incomplete answers here.

The FAQ had a full discussion of both the pros and cons of each type available. OP needs to be aware of it, and look to the "which manifold is for me"? Thread and read all about that.

Look at this from several angles, please

 

???? I dont know who you are

 

I read all the FAQ's.
They all give very general info on how the manis perform, which isn't what I was after.
My question was pretty specific. Will a fast spooling mani, ie log, bring the powerband down, meaning the turbo I posted, would run out of puff top end.

 

So you're actively trying to get banned again patchY?

 

How high do you plan on revving? Your Turbo compressor map would be a better source to tell where you will run out of its efficiency range and or risk of hitting the choke line....if that's the case a bigger turbo may be needed.

 

Stock rev limit.
Here's the map.

 

Mini Rams tend to creep as the collectors are wicked short and IMO would b best suited to an internally gated turbocharge or a turbocharger with a smaller turbine wheel that'll allow the WG to be the path of least resistance.

 

I prefer the full 'ramhorn' design over the mini-ram/quick4 - can mount almost any turbo with a S-cover or smaller.

This is my setup in a Civic with: Spoolin' Performance ramhorn manifold, 3" down-pipe, 38mm TiAL wastegate, t3/t04e 60 trim turbo, 9:1 CR b16 and ITR cams on 91 octane and 15 PSI. I love the spool/response, and it's just enough power to enjoy on the streets and to drive to & from work.

 

I see that this will go nowhere... once the OP gets a bit more in-depth in his inquiry and with some references from that FAQ thread, it may revive itself

 

honestly dude, it sounds like you already know the answer to your own question.

in this instance for puff on top end, i think you mite have more manifold then turbo if tryin to go over 400whp

 

I've seen a lot of people struggle with oil return lines using mini ram style manifolds; Just something to think about and factor into your decision.

 

The only one that is "easier" is with a Log manifold. So, to consider that is something that is "par for the course".

Return lines are inherently a pain, no matter what.

 

Based on this graph, the tune is....ehh questionable? lol

 

Agreed

 

my ram horn return line was pretty much a straight shot no issues
