I’m working on a complete kit.

My manifold and pigtails just shipped. Wish me luck fellas

So I just spliced my blue connectors together and wired how your picture is and I'm still throwing a P2005 stumbling and everything I'm just about to say eff it and go with lockouts.

Grabber is your vacuum plumbed the same way as shown in the picture?

Yes I do, but its only throwing a code for bank 2

Ok. Your pic makes it look a little like you have the IMRC port (the one that comes out of the front of the manifold horizontally) hooked to the brake booster.

I know what you mean about the P2005 code. I'm getting the same one. It would totally make sense to me that the IMRCs won't work right if they don't have enough vacuum running to them but doesn't really make sense that it would throw a code for only one side.

I decided to take a night off from working on my car but should be back at it on Weds.

From the picture a few posts back.

The "brake booster source" is where (needs vacuum) and (brake booster) gets it's vaccum from. The fourth connection in the union is when there is no vacuum and pulls vacuum from the intake tube but has a check valve built in so it's not a vacuum leak. I either have bad wiring (I soldered my wires) or the wiring schematic on the passenger side is wrong. My vacuum is set up how it's supposed to be

I believe I’m set up exactly like you and I’ve had no problems. Can you take a wider picture of the vacuum line setup?

I'm going to re solder my connections after work tomorrow don't know what else it could be.

Has anyone wired the 18 pigtails in and left the stock pigtails on there also? Would there be any problems caused by this? This would make a return to stock a plug and play deal without the need to resplice the stock pigtails back in.

from a wiring standpoint this should work fine.. however leaving electrical connections open to the elements is a bad idea.. asking to have a short. just rewire if you ever want to go back to stock.. snip the ends off and plug them into your stock manifold so they cant be lost.

Sorry Guys had to be quiet about the results for a bit but here they are...

Praise jebus, 2nd intake was NOT broken

 

[Monty17GT]

Is there a dyno comparison between stock manifold and 18 manifold on stock car? Can't seem to find one in the last 46 pages..thanks

+126hp and+50tq peak, nice. You went from the p-1x to the d-1x, just to be sure, testing was done on both manifolds with the d-1x correct?

Yes both test were with the D1X. The P1X was a while back but we had switched to the D1X a while back.
