"So the Kompressor is producing more than half of the 469hp factory rated motor? "
That would put the motor at 235 crank hp...probably not that low but I bet the motor only makes about 300 at the crank.

Weistec how much peak ignition timing is being ran in these tunes? Such as in the 574whp 91 octane tune car? And then for someone running the same setup but on 93 octane since I believe you aren't changing the boost and both would be running 17psi?
I know there are Cobra guys running 17 and 18* of timing on 93 octane and running 18psi of boost on 2.9 Whipples, and there are even guys running up to 21psi in those cars but most are in the 18psi range with the above ignition advance.
And where the heck are the 2 guys that have these things mounted on their cars that are posting members on here? They should be running by now.

I am not sure since they said they run conservative calibration after questions were asked about the power output on the 91 octane dyno they shared that is why I was asking.
Those Cobras were making around 630whp at 18psi and 18* with a 2.9 Whipple while running headers and cars running 17psi on 93 octane and 16-17* were in the 575 range so it seemed to be pretty close to the Weistec numbers, hince the curiousity of what ignition timing.

e55damgrocket, I don't know what the timing is on these cars but I can't see it that low with only around 13 lbs of boost, aluminum heads and 9:1 compression max. Too little of timing will cause an incomplete burn and really cause emissions to sky rocket. I believe this will also increase egt's

Well CR isn't as high as we thought but we are talking about 17psi on 91 octane and weistec said a very conservative/safe tune. I can see 15-16 degrees at 17psi being conservative. Stock timing is 14 or 15 degrees.

Well, I will bet to make power they timing would have to be in the 18-19 BDC range at the high RPM to get the peak cylinder pressure in the correct point of the rotation of the crank to get some work done. To retarded the peak cylinder pressure will be chasing the piston and not pushing it.
On the 4.0L V6 engine I make kits for we shoot 18-20 BTDC at 6200 with 10:1 compress in the 12-14 PSI range.

Had a slight issue on the initial engine start. Slight fuel leak from the rail end caps I had to square away. Pretty simple.
Fired right up and idled very smooth. Drives very nicely. I can see that the traction control is really going to burn through the rear brakes.
AFRs are tracking just as I expected. Usually ends up around 11-11.5 WOT and full RPM.
Timing is up and then tapers off as the IAT comes up. The IAT does climb fast and also recovers fast. Ambient is about 40*F and the IAT was pushing 180 a couple of times. That might get better as the air burps out of the system. There is no procedure for bleeding the air out of it. Going to do the cooling split very soon.
Just have a few miles on it. I will say the overall performance is better than the 180 crank pulley on the stock system and way smoother. It does not have that shock from the clutch engaging. It just goes.
Need to put some more miles on it.
It is very nice to be able to drive the car after it sitting for the last 6 months.

Gadget, like you said, all you need to do is split the cooling system. Running 200 degree water through it isnt helping. You have the same combo as the 575hp car in Wiestec vids, but setup to run 93?

An engines power is doubled with every added atmosphere of pressure with an effective intercooler. 14.7 PSI is one atmosphere or bar. 11.6 PSI from a stock E55 is 78.9% of 1 bar. If the car dynos at 400 RWHP with 11.6PSI, it would produce approx 223.6 RWHP without the blower.
Of course, these are approximations but it should be close. An intercooler that brings the air below ambiant can produce more than double the power at one bar but I think you can see the sense in the calculations.

weistec supercharger
Hay, Gadget that weistec supercharger looks awesome on your engine .. nothing like a monster supercharger . Good Job I'm waiting to see what kind of power and track et's people get with this set-up depending on their existing modds . I'm Glad your not having any real issues with this system , that's the real world test .... Weistec seems to be a really Good Company to deal with like the other top tuners ... Savings my coins NOW ... Badm

Got to take the car back out today.
Looks like the intercooler system is settling down a bit. IAT much more stable now.
Made one run to 150 and it pulls very hard and wants to keep right on going.
I was worried about the noise from the supercharger with that open element filter, but it is not to bad at all. You can hear the whine, but it is quiet enough to make me happy.
