Turbo Mani question.

Re: Turbo Mani question.
everybody here knows that log manifolds work just fine. They also know that tubular individual runner and especially equal length type manifolds make more power, but everybody weighs the pros and cons when they are selecting which manifold to run

Re: Turbo Mani question.
Since everybody here knows
Ans since evrbody who dosent even run a Turbo knows.
How come I cant get a striaght answer when I ask for numbers i.e. Gains % wise.
Off one system over the other.
There's gota be somebody who has upgraded from a Log. Who can give us some insight.
Ask me about bikes. I can tell you how much the power will go up, how much your top speed will go up. How your quater times will change just from upgrading your reeds, to switching to flatslides. Why is real info for cars so scarce

Re: Turbo Mani question.
I'll probably be able to answer soon
I turbocharged last week a H22A JDM with a lug type manifold.
And this week, I'm turbocharging the same engine, using the same engine management program, same turbo same everything but with an equal length header.
In both cases, the I.D. is 1.5". THe manifold design, basically, is kind of isoltaed since it'S the only difference between the two setups.
I'll have driving impressions on both setups, as well as dynos.
Bear with me.

Re: Turbo Mani question.
Ok this is a stupid question but when you say 1.25" or 1.5" are you refering to the inner dia or the external dia.
In our country when we say 2.5" they are normally refering to the external dia and the inner dia will typically be much smaller.
Do you guys have links for shops that sell bends in Mild Steel. How about using G.I.

Re: Turbo Mani question.
Who cares about the o.d.? Regardless of the wall thickness, the internal diameter is the one that mathers. For most 4 cylinders, I use 1.5" I.D.
When ovalized, it almost matches the ports perfectly. But I'm sure 1.5" is on the small side. As a result, it must be streamlining if not accelerating the flow. According to the above writeup, I understand low end and quick spool up is promoted by my headers, and the top end, well, is not bad at all but could be further enhanced with larger tubes. Since I build street cars. I won't bother going 1.75" unless specifically requested.
I can supply the mild steel, low carbide elbows (7$) and Tees (14$). They weld like a charm and the resulting manfiold, unless your welding is very very poor, will never crack..

Re: Turbo Mani question.
Each port is 1" wide with 1.5" high.
Equvilent circular section of my port is 1.2"
So I asume a 1.25" pipe will sufice.
Do you offer diffirent sizes. Can you post a pic of what we are talking about.
Yeah your manis do look quite neat.
Do you recomend gas or electric welding.
