O.k. i would apreiciate it if any one knows what to do with the air jet hose & metering oil nozzel hose? the problem I have is that the kit has them plumbed to the turbo inlet pipe. that would be fine if the maf was there. the maf has to be after ,the blow off. I temperaraly have them plumbed after the maf just befor the t.b. it runs good. it would not idle before i did this. the 2 (vacuum leaks) have to metered &, are now. I am afraid as to what could happen long term with the metering oil hose being pressized under boost. the jet air should not matter.
the greddy kits dont have this concern as for they have no blow off to speak of & can run the maf all hoses in the turbo intake but, have the typical issues turbos have with no b.o. valve. we have a blow off. If anyone has any knowlege of how to aproach this or has any questions please give a hit. I am a profesional tuner by trade but have no rotory experience. I am using the power mod piggy back & about got this car whipped. I am just very uneasy on the the metering oil hose.
p.s. any thoughts on timming .
we are running 8 psi intercooled, b.o., 550cc injectors, no cat, bypas coolant hose from t.b., Idles good .

 

I know this is a different kit, but this is how I have mine...jet air runs off the TB pipe(underneath, cant see it in that pic), and omp on intake before MAF

 

is the sfr kit blow through setup? if so it sounds like a check valve will be the solution?

 

looks like it is after the maf? will it hut the oil metering system if pressurized?

 

yes blow threw maf the check valve wont stop boost from forcing air into the omp unless installed the wrong way then it wont suck anything in like normal? did i missunder stand your reply

 

oops, yeah after

dont know about how it will affect it if pressurized

contact sfr...i dont think there are many on here that run this kit...maybe one that i know of

 

Well lets just say that the sfr kit has fab quality & componants 2nd to none (from experiance) but there are some loose ends like this concern(problem) I am working them. they are concerned & comunicating well but have not installed one in like 4 or 5 years & are not ell versed on this end of the car. it dont make sense but, it is a rotory!lol I am on my own for now

 

Hello and welcome. I am running the SFR kit and have been for about 6 months now. I have a thread with a build and some pictures. Im a little out of it so im having trouble figuring out what you asking about.

If your talking about all the vacume lines I had them all pre maf before the turbo inlet. I have an older version of the kit. I know it has been recently adapted to some degreee. Here is the link to my thead. Let me know if you have questions I did the install myself so I will try to remember the best I can.

it doesn't matter. The oil metering injectors received boost from the factory on older rotaries. They were hooked in after the airflow sensor and before the TB just as you have done.

 

Ok, I will pitch in.

The kit we make is similar to the SFR regarding the piping. This is how our instruction manual reads:

1. Oil metering jet hose goes to an included one-way check valve that we hook up pre-turbo (between the turbo inlet and the air filter). The valve is placed to allow air to enter the hose but not to be pushed out to prevent reversal when under boost. You can use any PCV check valve that will fit your hose, they are available at all auto parts stores.

2. The Hose for the injectors we plumb to a nipple right before the throttle body but past the MAF. This will keep the flow in one direction always. since this point will always have slightly more pressure than the lower intake manifold regardless of throttle position or boost.

This is the right way to do it and will keep the systems working as they were intended. Any other way could potentially compromise the oiling of the apex seals and/or fuel economy at low rpms.

Hope this helps.

Great info Chris :
I was actually still unsure where I was going to route of all that for my setup.

 

thanx guys super responses! especially cris. the only problem i see is the oil metering hose pulls alot of vacum and is hard to set the idle trims with the piggy back this car has if mounted pre maf. any thoughts

 

The oil metering pump hose is supposed to pull that much vacuum...I see what you are saying about the MAF though....we don't really care about the MAF because it does nothing with the Interceptor-X.

You can hook it up to the same place as where I told you to hook up the injector jet nozzle hose but make sure and keep the check valve in the there and in the right orientation.

we are using the power mod piggy back. we got the hoses & idle pretty good. thanx for the input on that.
we now are trying to tune for boost. we can not get the car to accept the increase in fuel under 6k. it seems like the o2 sensor has alot of authority?.. we have 550cc injectors & have added 35-95% increase in duty cycle with no change any ware no matter what! i even tried a global change of 50% on top of that with no change! any thoughts?
any one tunning with the power mod?

 

Almost no one here is using the PowerMod, I would switch to the Cobb AP, but that's me

 

The current setup of the SFR kit will not support the access port. They have made changes so you can but I dont belive anyone has tested it yet. I am currently waiting anxiously to hear how wanted2's setup works before I order the new pipes and a cobb. I know ray at PFS said he had issues with the powermod and fueling, i have the INT-X now.

 

the pipe configeration should not matter on tunning? what issues are you refering to?

 

Currently the MAF is post turbo and located in a posision that would result in turblent air thus giving bad maf readings. Its been fairly well accepted for the accessport to work well it should be placed pre turbo in a long strait pipe at a diamater of 3.5 inches. At least this is the ideal configuration.

As for the powermod i believe ray was saying he was having issues with lean spots that he couldnt take care of because of the injector configuration on the power mod. I dont know if that is true or not but that is why the kit I bought had the INT-X
