I know I didn't even think to see if your manifold was glowing. It doesn't help that your manifold isn't out in the open like Ben's. That and we were all wondering if you were going to put down more power then the Protege.

Gotta get a decent exhaust on that! A high flow cat and a decent diameter - 2 1/2" or larger.
If you haven't already, put some heat wrap around the cruise cable where it's against the heat sheild. I froze up 2 of them cooking them on track days. With that glow on the dyno you can see why. Some extra heat wrap around the cable took care of it.

Jason (enthuza) is going to be hanging on to my car for a few days and making an exhaust. We need to get our schedules together. No rush or timeline set. I told him I wanted something wicked, 3", and dual, and he's got a blank slate from there.
If I can get this freakin xede to datalog, I will actually start some real tuning.
Rob, I did not see your mani glow.

Nice on the exhaust. I've got an s4 system using Enthuza high flow cat and only a single 2 1/2". The sound is great and my 2860 spools great with it. Should make a huge difference. I went with an early model, 94, to avoid the headaches of piggy back since I have to DEQ.
Tune and exhaust and I'd expect at least another 40hp at that boost level.

no 240 mustang rwhp is not reasonable with only exhaust and tune. 240 dynojet, no problem, I am there or close after the slight tweaks from yesterday.

Really, really impressive. You've got the potato, I've got the 2560, so I won't be putting down as high of numbers as you.
However, your chart makes me want a potato. Damn.
You've also got a MS don't you?

Yea, Megasquirt. I gave up the comfort of the NB chassis to get the lack of DEQ trouble and a higher level of control by being OBD1. Paul has proven the 2560 to be a awesome up to 300hp. It's a great turbo for mid 200 levels and I'd guess that's why you went that way. No reason not to expect more of yours.
I'm obviously no turbo guru or wealth of knowledge and likely embarassing myself by thinking you could gain so much. You made good Mustang numbers pig rich and plugged up. I'm just anxious to see what happens when you get the new exhaust and better tune going.

Y8's. That's just mean!
My set up is the standard S4 tubular with the potato on it. 2 1/2" enthuza with a high flow cat.
Hustler is doing just fine. He'll get used to his current power level and start upping the boost by this fall is my guess. He's used to VW's and all the reliability headaches. Once he gains some confidence in the built motor he'll turn up the screws.
Seriously the power my car made seems to be an anomaly for the set up. I'm thinking of getting it back on the dyno soon now that I have a little more MS knowledge under my belt.

Alright kiddos, going back to the dyno on Thursday with the DIYPNP MS2.
I know I can't top Paul Rein's Machine, but dammit we're gonna try to give him some competition.

Realizing I never posted it here, this is my last run. This run has 3" exhaust compared to stock midpipe with RB 2.5" duals in the previous run. ~12 psi on the dynapack. I hope to beat this Thursday.

Had a very frustrating day at the dyno.
Not all of it was bad though. The horrible rattling noise coming from the front of the motor ended up being not serious.
Without boost control, and with the wastegate actuator holding the gate tight, car made 12 psi and 200 ft lbs before 3000 rpm on the dynapack dyno. Unfotunately it creeped to 17 psi by 4800. 17 is the magic number that overboost protection comes in and kills the power. Had 220 rwhp at the cutoff. These numbers put me in line to make power similar to Paul's Machine, which pleases me.
To keep boost at reasonable levels, we had to set the actuator rod to full loose. Spool suffered significantly. 10 psi at 3500, slow creep to 14 by 7000. Ended the day with 245 whp at 7000, at 86% duty cycle on RC550 injectors. 12.5:1 a/f up top, could not make it any richer.
Luckily I can fix the spool problem with boost control, and I've got an MTuned fuel rail. I'll also pick up a 250HP fuel pump.
245 sounds a bit low, but the fact that I'm running out of fuel with 550s says a lot. Since we were out of fuel, and it was already 5pm, we didn't even adjust timing. After the boost control and fuel upgrades, I'll try again. I don't expect to hit Paul's numbers, but I am going to get close. I credit it to the bottom mount turbo and straight downpipe.
We also did scope the LS2 truck coils, which are little monsters. Optimal dwell is 4.5 ms wasted spark. When I get a CAS and start running sequential, I'll bring them to 5.5 ms.
