The owner of Garage 808 and I are fabbing up my new manifold. SCH 40 SS 1 1/2". Its going in a CRX with a BW S372r and dual tial 44's. looking for some input and criticism

 

lookin good homie

 

Pretty hard to tell anything from the pics. Are you building a divided manifold, it looks like the cylinder pairing is wrong. I also would of tried to get the wastegates closer to collector.

 

cly. pairing looks right to me. 1-4 goes to the front side, and 2-3 goes to the back side.

in for finished pics. And more detailed pics to.

 

id have to agree i dont really like the wastegate placement. i mean i know space is tight but trying to merge your wastegates in at that angle to the 2 collectors is not going to work as well as youd think. you expecting exhaust gases to flow in the opposite direction of the path that its flowing. air doesnt make sharp turns unless you influence it. i understand this is a drag car and its not really important to you to be able to keep the boost low but still its very inefficient. any reason why your running twinscroll? how much power are you looking to make and what times are you aiming for?

 

If that is a twin scroll (looks like it) then the pairing does look off.

And why didn't you use thin wall if its a drag car?

 

the pairing is not off you tools. am i the only one seeing it is fine?

As long as 1-4 and 2-3 go into the same side, it's fine.

 

2+3 are going into the top "half" of the collector. That part of the collector is not paired.


This is how it's supposed to be.

 

sorry im blind i thought the runner all the way to the right was actually on the third exhaust port. sorry!

 

haha, i was woundering what was going on there. i let this slide sense your blind....

 

looking really nice, more pics please!

 

so the wg elbows are just coming off 1/2 of part of the divided collector? they are not within the joining of the two pipes? i cant really tell.

 

the wastegates come off of the different sides. it is a divided manifold, 1 and 4 go to the front and 2-3 to the rear. the WG elbows are after the 2 pipes merge. i will hav updated pics tonight

 

is this car going to be done for this year graig?

 

Trying damn hard to make that happen

 

Its hard to tell from the pics actually. I thought the same.

 

do work son!

 

we will be changing the routing of runner 3. it'll drop out and under runner 1, then into the collector

Collector from front of car

collector from top

mani from pass side

mani from top driverside view

 

i really like it minus the waste gate set up. looks really nice, love the routing of the piping

 

ya, we were really limited as to where to put the gates, where they are at now, the just fit under the fiberglass front end.

 

that manifold looks very heavy for a drag car. like i said previously, why didn't you use thin wall tube? looks like you have plenty of room to run braces to support the turbo.
just a thought.

 

looks good graig. tell james to hurry up and finish it. is he doing the welding?

 

I went with heavier material for strength and weight. the car was very close to the min weight for the class i want to run, and weight out over the front is good. i realize i could have just added weight in the traction bar or frame horns.

yes, james is doing the welding. we will be re-doing the #3 runner friday, and then he should be welding it soon, after that the DP and dumps will be fabbed, and then the new charge piping

 

looks sick! make sure to post up some more progress pics, i want to see how it turns out.

 

tell James to get his car done too
looks hot homie
