I would say that I am feeling 14 again. But that might give it away.
Don't it make you wanna sing " Blue " by LeAnn Rimes ?
Will see you Friday ! -
And the crowd starts to gather in great anticipation of the "BIG SHOW"

Can I chicken shit my way out and say that I have a bad wheel bearing on my trailer!
-
That is my rear drivers side wheel bearing. I have a new set of bearings and seals in the garage. So truthfully I can't use this as an excuse.

Double nut that SOB and go for the gusto!

I'm just glad they warranty their engines. I could just put a steel slug in between the wastegate and the cap. I wouldn't do that. I promise.

What is the biggest spring that DDM has cleared for this engine. Didn't Dave say 400HP?

NO

Ill take "What is a frigged up bearing for $1000 Alex" -
I think it's the bearing from your turbo after trying out the blue spring. Is the spring blue because it will keep the power up longer.
-
To be honest I think I have found the max that the turbo can push. It seems to be topped out at 13.8. I am changing my muffler back to the one that I originally had tonight and see if I can get the flow back up a little. So far I'm thinking the side exhaust is killing my exhaust flow.

The trailer bearing was weirdly just loose. Not sure how it loosened. It has a keeper on the nut. The inside bearing and the outer bearing are perfect.

@rabtech will be very interested in this testing. Would be interested in @Bill from Hahn RaceCraft Hahn would think or suggest on that. -
We were very happy to get one of the early 2.5" Welter Performance dual exhaust setups to test with our DDMWorks supercharged Slingshots and we are pretty happy with the results. While driving the exhaust is still able to be heard, but since it exits behind the Slingshot now, it makes cruising around much more enjoyable than with the standard or side exit exhausts we have driven. This setup seems to be a nice compromise of sound and power that I think a lot of people will be happy with.

The main reason I think im being held back by the side exhaust is due to it having only one exit. There muffler on the side exit only let's the turbo exhaust pass out of one opening and the other side is the wastegate. Where the original exhaust that dumped out below the SS has an open center section. So you get both 2.5" exhaust ports to breath thru.
Remember Hahn didn't build this system to go all the way to 14PSI. He built it to perform within the parameters of 8.5 PSI.. The side exhaust performance is flawless under those conditions. I am breaking some new ground when I turn the dial up to 14.
One thing I did after talking to @iNewton is put my stock fuel pump back in. I had the Aeromotive pump in it and it seemed to act fine. However when I started upping my boost it started flooding me out.
Now with the stock pump in place and the bigger fuel rail I don't have any issues with running lean.

This is getting quite interesting.

This maybe good news in not having to switch out the fuel pump. I have the DDM fuel rail and i was amazed how much more volume was in the bar for the injectors.
Will be quite interested in seeing the exhaust difference
Does the WP exhaust have the dual pipe as well? It seems that it is one pipe back to dual tips. Which exhaust has the dual?

Man, now this thread just wants to make me go out and inspect the wheel bearings on all of my trailers....
