whatz the advantage of either :
wiring open ur ports or
removing 6port sleeves?
any gains? list the advantages and disadvantages that u can think of please....

 

BUUUUUMP

 

If they're broken, then there's an advantage to wiring them open.

If they work, leave them be.

 

I would vote for removing the air pump but making a different type of air supply for the actuators. The reason the ports are there is to allow a flat torque curve. Do you want your RX-7 to drive like a Honda?

 

Go read the thread on the n0pistions.com forum about it. I dont feel like typing it again here.

edit: such ******* bulshit.....

 

I do not recommend removing your sleeves your car will loose so much torque and you still have those rods messing up your airflow....either wire them up if they arent functioning properly or keep them if they are working properly

 

i wired them up when i took the airpumnp off... they were working from the best of my knowledge... what did i do ? messed em up ? loose torque?
jack

 

Jack the ports are for torque in the lower end of the RPM scale.

If yours are wired open, then you lose the benefit of having them open @ a specific rpm.

But when your WOT. you are seeing no loss from having the ports wired open.

 

well seeing that im usually at WOT i guess i feel no effect. levi are urs wired open? mine have been wired for about 6 months now. so i shouldnt remove them? replace them with pineapple sleeves?

 

What are you trying to attain? Max power? Functioning Auxilliry Ports, to say the least?

Don't wire them open. You lose far more than you gain. Don't lose the Sleeves either, unless you have a massive B-Port or simular. Put the PR Sleeve Inserts In and follow my proved thread that will ensure max efficiency from your "6 ports".

 

ok so remove sleeves and replace with pr sleeves? im just thinking about it and asking the forum silerrotor.
just was trying to see the advantages/disadvantages.

 

Mine are open all the time.

If I am not WOT I don't care about what I am missing as I am not needing it.

See what I am saying?

 

I would recommend pineapple racing sleeves or even talking to mazdaspeed7 and picking up a pair of his...

 

Just put a 25 shot of nitrous in each hole and then you won't miss any torque.

The best part is the secondaries are not decreasing any velocity being the secondary plates are still shut, you only notice it if you smash the gas to the floor and then once the fuel turns on, do you feel the gain.

 

lol kool so im not really midding much witht them wired open? right?

 

Ive completly removed mine and ground down/removed any rods or anything else protruding from that area so air flows fairly well. I dont have a lack of torque, but most of my power all comes online after 4500. I havent lost to any car with functioning 6 ports to show me that keeping them was better.

 

OK GOOD ..... so u r saying take the ports out and leave them out? have n e pics with them out and manifold on?

 

Come by my house and check out my 91 intake I have been porting. Its setup like you are asking...with a little FAF Racing tech in it...LOL

 

but i dont have a 91 intake. so what would that do for me? should i get pineapple racing sleeves?

 

Jack the lower manifolds are exactly the same.. it the upper portions that are different.

If you want to see what I have done to that area, just swing by the house...

PS: Its Top Secret ****....

 

lol i see.. haha only FAF technicians can see the results of the almighty 91 ported intake..?!? lol

 

if I had to choose again, I would have done the same thing. While you have everything off you may as well perform the TB mod and remove all emissions/airpump and replace all your vacuum lines. Remember to use all new gaskets. I ended up with a vacuum leak the first time and had to do it again with all new lines and gaskets.

 

You can't wire the ports open any further than they would open normally, so there is no advantage in this unless your ports are not working.

BTW, Scott removed the ports from his car a few weeks ago because they were jammed shut. The car runs better now, but I don't think it's any better than it was when the ports worked. He's going to do some type of funky porting on it later, so I'm sure the engine will achieve significant gains then.

 

Removing them will give ultimate power and increase flow. When I installed my headers I couldnt run my ports properly so i had the airpump do it. After some opening time tuning at the track I noticed that they are not needed when racing or driving it hard. So I then removed my airpump and wired them open. Now I plan on removing them completely to increase airflow.

 

ok so more of u think that removing the ports do more better than worse? n e one see any improvements with pineapple racing sleeves? i have a new exhaust manifold gasket thatz why i was wondering all this. while im replacing the gasket i was thinking of doing this.
