all you have to do is watch the boost, if you start getting creep then at that point yes, you have to do fuel mods or highflow. Im just saying that its possible that the wastegate can hold the boost at 10, and if that is the situation he will need no further mods

Gotcha....and he does have a PowerFC, and those maps should give him a small amount of safety, certainly more than he would have if still on the stock ECU, like some have done .

Still, I would think he better watch it closely.

Thats all fine and dandy until he gets on the boost on a cold day and gets a nasty boost spike. You can watch for creeps but one good spike to 13psi and he could easily break that engine. I've seen it happen more than a few times over the years at local meets etc.

It's always been my experience that when you add a mid pipe your playing with fire. If you want to be more safe and less sorry then don't play the odds. Either leave off the mid pipe all together or get some larger secondaries and re-tune the maps. I would worry less about your boost gauge and more about your air fuel.

nopistons94

If your running power FC all you have to do is set your boost 25% lower than the max you want to run. IE my boost on the power FC is set to 9.5, it will creep higher, but when I hit 12.2 it will cut.

Fd3BOOST

What will cut? The fuel? Why anyone would want to set up a car to hit cut fuel as opposed to doing the mods so that you can floor it with out having to hit a fuel cut is beyond me. If you talking about the wastegate then you already said yourself that works up until a point.

All I am saying that if you run a mid pipe without adjusting your A/F's properly your asking for trouble.



Your going to want some larger injectors. Then re-tune with a wide band. A fuel pump only increases the abilty to run more fuel it will not automatically compensate the map for you.

nopistons94

I never said a FP would increase fuel? I have my injectors and fuel pump coming in a few more weeks. Yes I do have the fuel cut set like that, simply because you can never be too safe. Sorry If i didn't do my mods fast enough for you, but everything will be sorted out over time. As for now, I like to keep my motor running if I have the need to drive it at WOT, which 99% of the time doesn't happen. And well if that 1% does, I have the fuel cut to warn me to back the hell off

The reply to the fuel pump comment was directed at Ben and not you. He posted that he thought it would be ok to run the mods that he listed with only a Power Fc and a fuel pump.



nopistons94, I'm not knocking your fuel cut as a temporary fix. I think it's a good idea as a just that " A temporary fix" I just don't think one should plan to modify a car backwards. So long as you understand that setting up a fuel cut is sort of a band aid over the real issue which is trying to run a mid pipe on stock fuel. You can mod your car however you like obviously but the smartest way is to leave the midpipe off until you can supply the needed fuel to run with it on the car and not risk breaking your ****.

Sounds like the split air pipe comes off the back of the manifold..

Right I`m off from college now so I have had a chance to have a proper look at it. It goes from the cat to a braded hose which goes up into the car, It then goes to a plug under the carpet, I cant follow it any further.





Thats why I was asking the questions buddy!! I didnt really know.



Anyway what secondaries do I go with? I want to go single next year and try and get around the 500bhp mark, if I can, so I dont really want to buy more than I need to.

Signal 2

500 bhp translates into roughly 425 at the wheels. Not an authority, but to do that safely, it will be hard NOT to buy something you need. I envy you and the money you must have while in college. I drove an old Malibu and worried about having enough for gas (OK, and beer too ) from day to day.
