Dyno Lindsey super 61 dry
Well, I just got my car back from getting it tune after the new turbo. I put in lindsey super 61 dry turbo, wrapped headers, wrapped turbo/downpipe/part of intake pipe(to turbo), clutch mater/slave cyclinder as well as the connecting pipe between them. First off, the clutch, wow feels much better then before. It was starting to stick on my half way up and didn't feel linear with pressure when releasing the pedal. Now it feels a little more heavy but very good feeling all the way down and up.
As for the turbo/power, I have heard that mustang dynos don't put as high numbers as dynojet. I proved that big time when I car my car tuned. My car put down 240rwhp and 300rwtq two summers ago with out this turbo and now after getting all tuned and everything, it says I am getting 232rwhp and 244rwtq. I am uploading the picture here (hopefully it isn't to big). The curve looks nice on it and holds tq pretty nice compared to the stock tired K26/6. When you floor it in the car at say 2,500 rpm, it sounds like a jet up spinning up. I am running 16.6 psi right now and plan to keep it there until I get my head o-ringed/rebuilt. The boost holds all the way to redline as well from looking at the chart. When looking at the a/r, there is the spot at 3,800-4,200 that is 13.6 because he said when it was richer then that, it wouldn't sustain the power later in the RPM range. Also, the air line looks rough because of the sample rate. He printed me out 10 pages worth from 2,200-6,000rpm range in increaments of about 4/6rpms showing the air/fuel, power, tq and psi. Anyways, I am happy with it. Coming home on the highway was pretty fun!! Before my car was quick on the streets and just OK on the highway as for power but now it just pulls and pulls.

Mike your AFR is very choppy! Figure out what is causing it. Start with the BOV.

That looks real low - on our car, the Super 61 (T04B, #8 hotside), with TIAL 38, #55 injectors, MAF, 3" exhaust produces 310 rwhp at an AFR of 12.2, full spool-up at 3800 rpm, and a torque of 450 Nm (331 fp), all at a max boost of 16 psi. We were told that this is not much for that turbo, checked all the vac lines, BOV etc, but were unable to get more power. The turbo does sound like a jet engine. Once - on a mixture of 98 and xylene, we tried 1.35 bar (19.5 psi) - and the engine really came alive.
Could be the BOV as John suggests. Is the camshaft timing ok?

Yea, they checked the timing but I have Vitesse chips/maf/piggyback in the car, plus 55lb injectors, cat-bypass pipe, gutted muffler, Tial 38, newer vacuum lines. My bov is the Saab one that I put on some 3.5 years ago, with this set now, is that still fine, or should I be looking for a different one? All my vacuum lines look good and like I said, about a year old. Everything is plugged in and zip tied. My hard pipes (still OEM) have the beefer clamps on them.
DrRon, what kind of dyno did you go to? Was it a mustang or dynojet??...

I put down 315whp at 18.5psi and Super 75 on a Mustang with no leaks and fresh motor and all mods in my sig.

Mike, I think a couple of us are going to head to that Back Street Dyno sometime in October if you wanted to try it out on a Dynojet. Those numbers do seem low. I put down 318 last year on my Super61 with cracked headers. 400 rwhp has been seen with this turbo.

Mike, forget about the performance for a second. Your AFR is way off, find out why. Did someone tune the PiggyBack to get the AFR as it is? Out of the box, the MAF gives a much better AFR. Email me a log file from your PB, I'll take a look at it.

John, I know he did change the fuel some but I also know he added 2 more degrees of timing, so when I sent it to you, take a look at that as well. Thanks
