did any of you guys get a look at mazfix rx-7 intake and if you did what were your thoughts.

 

Purdy.

 

Hmmm!
It could do with a little polishing!

 

Phil Laird S6 intake manifold.

 

 

That is a very nice looking manifold. How much do they run? Or are they even available to the public?

 

damn that intake manifold must cost a fortune.are those casted or machined ? is that mani going an any perticular car?or do you just keep cool stuff strooned about? lol

 

I want one. Kinda like.......now

 

Where can i get one of these please ???????????

Ammm!
It's not mine. That's a pic I got from another forum.
There are many pics of Phil Laird's intakes floating around. Most are for the 3-rotor applications and the one from the 4-rotor BMW.

 

so can you guys tell me why all these guys are running these square intake manifolds .

 

Mainly for volume because of the fuel type being used. It really does not make a difference round or square to a certain point but the size does. It's actually not square but more retangular with curve ends to follow the original shape of the ports on the motor.
Intake flow is a balance of both mediums. You got 'fuel' and 'air' and sometimes when the ratio of one is a lot more than the other you got to compensate. Methanol/alcohol displaces a lot of the area that the 'air' side of the equation would normally occupy so the need for much larger runners. The same design would not be as effective say with everything else being equal when using gasolene for fuel. Even where the injectors are placed on an intake can effect the flow.

 

Hogan's also makes intake manifolds for 2 & 3 rotor motors, and is said to be around the same price as the GSR unit. I think someone on here is running one on their 13b (rene?) im not to sure..
heres the link to a thread from back in the day about Hogans.https://www.rx7club.com/showthread.p...=hogans+intake

 

the oval intakes are suitable for low end torque while the rectangular is more for all out racing also the air comes out of the compressor in a swirl so turbulent flow is restored by placing a square cornered plenum . crispeed maybe you can build one for v8 kila.

 

No need for that low output application!
Every application have a combination that works.

 

that intake system looks good but the rectangular port is better for racing look at abel ibarra and archie setup rectangular ports better for power at high rpm .

 

Holy mother of all intercoolers!

 

The oil and water temps are going to love that mother of an intercooler. That'd create one hell of a pressure drop too, wouldnt it?

 

jesus h....so thats where the drag international car has been! god i hope its still a stick trans! bolt a getrag v160 to that bad boy,that would be awsome!

 

It still got a stick trans. It's a 6-speed also but not the one mentioned above or a T-56.

 

The shape of the port does not dedicate rpm useage. Since you mentioned v8killa that has round ports and the power never falls off untill after 10k rpm. PP na applications don't use round ports and they go all the way too the moon rpm wise.

Never took all that into consideration but now that you mentioned it thanks for the advise.
Next time I'll take a pic with the oil coolers and all the duct work in place.

In all the years I've been doing this I've never seen a large intercooler create a pressure drop for any application it was designed for. It's not like it's going to be running a stock turbo at only 15psi!

 

Tranzilla 6speed?

 

IRS?

 

Are you going to measure for it on that setup? I'm curious to know the results if you do(PM) from what I've seen every time you use dual outlets like that you get a pressure drop. Then again maybe it was inlets it's been awhile but I do remember no way around the pressure difference when having twin pipe work.
