My 2008 E63 with the Weistec stage 2 kit made 530 whp and 499 lbs ft of torque. I'll post pictures and videos later today. This is with long tubes and trunk tank. I picked up 102 whp and 85 lbs ft of torque with the supercharger and trunk tank. All motor the car went 12.17 at 113. I'll have to wait till next year to make a pass with the supercharger.

THESE ARE DYNO JET NUMBERS EVEN THOUGH IT WAS ON A DYNO DYNAMICS. THIS IS DONE THROUGH A TEMPERATURE CORRECTION FACTOR.

Good job mate now go out and make some passes you should have a 10sec pass there with traction

layzie12g

Nah. I'd be happy if it ran 11.50s. For some reason my car has always been down on power. I'm still not exactly sure why. It is what it is though.

mr747

You 20hp down on mine which isn't really that much

It's all in your 60ft get a good 60ft and you will be flying

Good luck

Your car only made 550 on a Dyno Jet? I also have the fat boy E with the pano roof which is really heavy. I have 200 cell cats and no x pipe which is costing me a little.

mr747

Yep that all it made bud

Yep you are a fatty but pull the Sears out and stuff to compensate
I don't have cats either

I think you will do ok with lots of practise

I've made a lot of quarter mile passes in my life. My car will still dead hook. Not much driving involved with these cars. I'm really anxious to see what it will do. I'm betting 11.55 at 124 with a 1.7 60 ft. That is if the car will still dead hook which I'm sure it will.

It feels good though. It feels so torquey compared to before. A full bolt on E55 made 497 whp and 617 lbs ft. I'd like to race him. He was around 18 psi on the stock supercharger.

Has anyone done the larger Weistec crank pulley with the 2.3 liter supercharger? I know a 2.3 liter Whipple can make quite a bit of power. I know the tranny will die, but I always want more.

You will see when you get to the track this car is a a lot harder to drive now you will be pulling the paddles a lot earlier then before cause if you don't you will hit the limiter

You will not be able to use sport at the track your car will not like it
M mode has the most line pressure for the tranny I suggest you use is mode all the time otherwise you will just kill the tranny

Weistec does not offer pulley upgrades on the stage 2 blower if you want to upgrade its stage 3

Your heads will lift if you lift the boost up anymore on a stage 2

layzie12g

Ya I read that in another post you had. I did not know that M applied more line pressure. I will use M. Previously I ran in the car in sport and let it shift itself. Lifting heads sucks. My Eclipse lifted the head with standard ARP studs and 35 psi. It blew a freeze plug out of the block. I knocked a new plug in and dropped in the tool steel L19 studs one at a time.

mr747

Once you get the gear changes right it will run a good number
My suggestion is pull the paddle around 5k or 5200rpm that will usually change before the limiter

Asher4799

Good numbers! And good advise thanks guys!

You have to remember correction factor when comparing dyno numbers. People should be using SAE but usually elect for STD or other factors that give higher numbers.

Don't worry about dyno numbers. Go out to the track, do some runs and your MPH will tell you everything.

Once you look at the slip, between ET, 60ft, 1/8th and MPH we will be able to pretty much pinpoint how good the car is running and where you can make improvements.

^^^ agreed
