Racing Beat CBE Installed.

[Greyspeed3]

Looks good

[bioevolve]

500+ mile update:
Sound seems to be getting alittle deeper. Tips are getting sut on them, I'm running a little rich lol.
Since the exhaust is now breathing better, my boost is steadily creeping and now I get boost cut around 5400-5800rpms 20-21psi & 22-24psi spikes!!!!!!! Did several runs to verify it wasn't a fluke. This is with Stage2 91 103.
Guess I will have to step down to Stage 1+SF 91 103 now until I get ATR for the AP.
Row #21 is where it cut on me.

Do you have an aftermarket downpipe or a gutted cat? Surprised it made a big enough difference that you started creeping/cutting.

*Edit: Picture clearly shows you don't have a test pipe. Sorry.*

[bioevolve]

I have a gutted stock test pipe on.

[DeadWayt]

Do you have any useful logs from before the CBE install? It's not that I don't believe what you're saying, I'm just surprised that a cat-back made that much of a difference in restriction.

Here are 2 from 2 days before the CBE install.

I think stage one is only going to cause your boost to increase.

You're right, it did that same thing but not so high on the boost. It cut between row 19 & 20 at a lower rpm.


Went to stage 2+SF 91 103 for now, have not WOT yet. Awaiting 100 miles and key cycles.

And judging by your IATs, you can't blame cold weather.

[bioevolve]

LOL, true! 80f-95f here in FLorida.

Bio said "Only thing I didn't like was the regular clamp, would have liked a band clamp or something better. Anyhooo it still got the job done for now."


I'm considering the Racing Beat exhaust. I wanted to ask you if you think this stainless clamp form jegs would work instead of the one supplied?
Would the 3" size be the one to get?
JEGS Preformed Stainless Steel Exhaust Band Clamps - JEGS

Thanks

[bioevolve]

That should work, I was looking at that on Jeg's and Summit Racing. Might order me one to try out also.

Still getting overboost, just got a cel P0234 overboost condition. Beta to the Final maps stage 1 thru stage 2, tried 6 different maps.
I just took out 2 shims from Forge BPV with Blue spring, hopefully that will fix it. We'll see in the next couple of days, if not, change to the yellow spring with 2 shims and go down from there. That should help with holding boost lower throughout the rpm range right?
19-21psi upto 5000-5500rpms is great until I hit boost cut lol.

i lost my springs the damn thing came with it and i misplaced the f***ing box..FAIL

Sorry to hear.


If I can't remedy the problem by friday, I will put the stocked catted TP back in to create some more back pressure and slow the stock turbo down.

hopefully you get it resolved

[bioevolve]

Update: Now I have the stock catted test pipe back on, Sounds to alittle more quiet lol. 11'ish megs WMV:

Will have to drive it after restting the ecu, hopefully it will fix my overboost condition. 2 shims and blue spring back in the Forge BPV. I know I could use a BC, but don't have one in hand so the stock catted tp should work. We'll see.

Hey Bio, did you check to see how well lubed the forge is when you changed the spring/shims? Could be sticking?

Yeah, that was the first thing (relubed the piston and o-rings) I did before switching out shims and springs lol.

[bioevolve]

Ok put the on Beta Stage 1 93 103r and it has calmed down the overboost, I will have to play with ATR with the Stage 2 stuff later.

Got a 3" step band clamp off ebay:


Checking fitment.

Putting together down by the Y-pipe part makes it alot easier than trying to put it together at the joint.

Slide it up and start torquing lightly and you hold it in place then snug that thing down hard.

Done. I like this WAY better than a regular exhaust clamp.


I had to smash this heat sheild down to get my ratchet , extension, swivel & socket on.

It bends back nicely lol. Enjoy!
