I have been using a Greddy Profec B Spec II but they aren't ideal for this much boost so I'm trying Kevin's MBC for the time being.

 

Was the last dyno and drag runs with the MBC or the Profec?

 

Profec

 

How're you finding the issue with an MBC and boost creep or boost taper with your WGA setup?

 

You consider switching out to a 3 port mellon?

There is even a way to do gear dependent boost on the stock ecu. Right now mine is setup very similiar to how a MBC would act just pure WG Duty% adjustments slowly ramping up to redline to hold boost.

Haven't yet implemented the boost control features yet but i have the scaling. I'm also about to release the rom I've been tweaking for the past week. Right now its sitting pretty at 0.2 AFR deviation for the cruising points from 14.7 AFR. I found that my EGR was giving me an artificial lean spot in the high-mid cruise range so i disabled it.

Need to test it in the morning see if the air temp correction is at the right spot, should be really close if nothing else.

 

I don't log boost and it rips through the gears way too fast to be watching the guage

I've been thinking about trying an air pressure regulator, some of the high boost diesel guys do that.

 

I've thought about it but really don't like the idea of needing a laptop to adjust the boost. I might give it a whirl eventually after I get some other issues sorted out.

Right now the lack of traction is really bothering me so I'm fixating on making what I have work with a different launch technique and AWD's DS coilover and custom springs.

 

went to the track the other night and only got one pass, 1.8 60' spinning, lost an IC pipe in 4th at 7500 and coasted to a 10.6 @ 123, 1/8th was 108.75 a new best. It's been consistently picking up 32mph from the 1/8th to the 1/4 previously. Maybe that would have been a 140mph pass.

Are you still on stock fuel line/fuel rails/fpr?
Did you get the Buschur dual feed lines as well?

man every time I read this thing i always want to start buying parts but something always come up for me, school, bills, emergencies, and all other stuff. Well mellon keep up the good work because i'm sure the vendors are loving it. I have read this whole thread several times since i first came across it in nov 2007.

 

glad you enjoyed the read. I was hoping to hit the track again this week but it's nothing but rain here and I have a customer coming from northwest Arkansas for a road tune and some minor parts installs anyway.

 

This car has come a long way.. Great work mellon

 

The *** KING ***

 

whew, just wrapped up that e85 tune for my fp red customer... 522awhp 473tq @ 39psi hell of a car
