Well that was assuming ideal VE like I mentioned, if Scheide's car is 90% efficient we'd be more in the 62 lbs/min range.

 

Chris-

if you guys sell any local to us, let me know- Id love to see what one does on our dyno!

cheers

Chad I would be interested but I need more fuel and to finish my tune.

 

You're just using 3-port right now right? Nothing wrong with that at all sir! For me, I like having the hybrid setup, I can manually change boost if need be quickly w/o a laptop, but still get the control of customizing the boost curve.

Just kinda what I mentioned above. I've posted some write-ups and diagrams on how it's setup in the ecuflash section, PM me if you cannot find them. It's a nice mix of the ease of adjustability of a MBC but still help eliminate taper that these stock-frame turbos enduce.

LOL this was not on a dyno, I just was doing pulls on my way home from work I consistently rev the car to a hair over 8000 but looks like now I will get a little more by revving it higher, who knows!

That is both manly and funny at the same time. I love it.

BBX you mean!

 

Mine pulls all the way to 8800 for the most part. The boost curve could use a little more wgdc I think up top and it wouldn't drop off at all. I bet yours will pull all the way to 9k unless you start to max the turbo

 

scheides-

yep- i made the mistake others make- LOL i meant BBX!

How close do you figure you are to maxing out the new pump at this power level?

 

Close. I was running 33psi at ~7500rpm during an initial pull and AFRs were at 12.5. Lowered boost to 31 up top and it's now in the high 11's. This sucks because it's on E70. I'm going to need to do something once E85 comes back in a few months. Gah the cycle continues!

I will post this in the walbro 400 thread too.

 

ps my MAF is now hitting 4.93v on my 3.5" intake around 8100. Weeeeeee!

 

That's a lot of airflow...

 

Time to go speed density. I wonder what mine would be being I run a 4 inch intake? Half inch makes a big difference.

 

The X comes standard with SD from the factory It uses both the MAF and speed density.

Also our MAF is a hotwire MAF, so if he really needed to he could just go to a custom 4" intake (or really just 4" maf housing) and it would give him a ton more room.

 

Ricer math kinda works out...I made 380whp at DB Performance on my stock MAF housing, 3.5" intake cross-sectional area is 1.39 times bigger, 1.39*380=529whp, or about 610whp on a dynojet.


IDK if I'm ready for that level of commitment I'll prolly just rock the 3.5" and push it to the absolute limit, I'm guessing I won't quite flatline it, no biggie.

 

Yea I don't think a 4" is necessary for stock frame either, you should be alright. Your rice math seems about right honestly. I figured about the same, I thought 610-620whp dynojet was about where the EF4 will run out. I made 495 on 27psi at DB so I think 530 on 32psi or so is possible.

 

That is good to know. They are doing the sd setup like they do on most of the Chrystlers and Gm cars. Learning more about the x is interesting, but as Kracka suggested go drive one. Having a hard time finding a dealer out here letting me. All the info is still good to know for when maybe one falls in my lap as my 8 did.

I will tell you it helped my car out alot. I mean clipping wasn't available when I ordered my turbo, but I noticed a huge difference obviously when I went from my Buschur 2.5 intake to a 4 inch off my talon that I had to use.
