I'm sure it feels awesome up top, but that low and mid leaves a lot to be desired.

Boost creep is a pain in the ass. I have to deal with this kind of shit a lot with the cold weather here, which makes boost creep much worse. The VF52 Subaru's get it bad with a catless downpipe for half the year here, they are often fine in the Summer, then it gets cold and then you can't keep the boost from going over 20psi on it's own. With the newer more efficient big turbos nowdays, it happens easier since the turbos just want to make boost and you end up having to set a low revlimiter if running on pump gas. I have an Evo 8 here now with a 35R on it that boost creeps to 30psi no matter what and it's a pump gas car. If you run less ignition timing to try to keep it from knocking, then the boost creep gets even worse.

They were trying to run wastegate boost on this car that I posted which is 15psi. It's a pump gas car and the single wastegate got over run. He said it spiked to 34 psi at 7k rpms.

So it was more of a funny picture, but it looks like the turbo is pretty potent on a similar motor, I am excited.

So the torque is low down low just because it starts out at 15psi.

Wow, that's crazy. I know Cobb had to add a 2nd external wastegate to Chkmgnt's car for this very reason.

Glad I have twin comp gate 40's going on this thing, that is all I am saying!

Should be interesting...twice the wastegates means twice the epic ear splitting dump pipes!

Have MAP recirculate them for a more pleasant WOT tone.

Hmmm, nah....

I like the noise

And the extra power. If it gets annoying I will have them modify it later.

**Kracka** · 04-03-2013

I don't buy the extra power statement [assuming a properly sized and designed exhaust system], but to each their own

I dunno, I have seen plenty of results showing gains by switching from a non dump to a dump and picking up significant power.

If I didn't do the dump I would think I'd want a 3.5" exhaust at that point.

It's what I am getting for now so I will go with it.

Murlo needs to save his money so he can buy a corvette in a couple months.

**Kracka** · 04-03-2013

Group buy on C7's?

Hmmm, I'd have a tough time choosing between the c7 and c6 z06 honestly. I think I'd go z06 as the aftermarket is there for it.

**Murlo26** · 04-03-2013

Starting to really get excited now!

Can't wait to see this in person, looks beautiful.

**4seasons69** · 04-03-2013

Looks good!

**JET** · 04-03-2013

Looks awesome! Nice fab work MAP.

bramagedained · 04-03-2013

Two WGs is definitely the way to go.

My car will creep pretty bad with just one WG.

**4seasons69** · 04-03-2013

My car also creeps really bad with only one wastegate. I would like to add a second but I'm not too worried about it at this point though

**Murlo26** · 04-03-2013

Anyone know part numbers to get new OEM pieces for the following:

I am missing this stupid cap here for the AC line (i think)

My terminal cover is cracked and doesn't stay on well anymore.

I was struggling to find these on mitsu parts .net, any help would be nice.

call dealer?

**Kracka** · 04-04-2013

PM Trogdor, I'm sure he can cruise over to the parts counter and have them ordered for you.
