Dyno results for the built motor and s/c
 

Well I got to the dyno today and did three pulls. The numbers were bad but there are a few issues to be resolved. One, I need more fuel pressure ( i.e buy a walbro and an adjustable FPR), Two, there was a possible boost leak and or belt slippage, and three the leak in the exhaust needs to be fixed. The leak was causing their AFR numbers to be skewed. The one good thing is that we seem to have corrected the curves with the new cam profiles. The curves look great ( they just need to move up a lot):)

Sorry in advance that they are just photos of the charts. My scanner is not compatible with Vista.

BTW red is HP, blue is TQ, green is boost, and black is AFR

so, what are the peak numbers for boost, hp, and tq? hard to tell from the photos. thanks.

Boost 7psi
HP 228.6 @ 5782
TQ 223 @ 3752

Nice... Any chance you can take some video (in car and outside) of the car?... I'm curious as to how it sounds and accelerates :)

So this is only at 6.5-ish PSI right? What are the theoretical numbers you're looking for at 12?

actually looks like it's 5.5ish psi. Looks like he has a lot of belt slip. Looks like the motor is making torque out to 5750 rpms so with the bigger pulley and the belt tightened we'll probably see some pretty big numbers :)

Now when he says that the motor is "Built"... What exactly has been done to it?

pistons, rods, and cams

Michael - have you come up with an improved belt tensioner, or do you think sicksubie just needs to tighten the one he has?
-Bill

Tighten the one he has. Remember we had no choice but to make the supercharger pulley as small as possible to get it to fit under the hood. Even though we got exceptional belt wrap on the pulleys the belt still needs to be very tight.

And that was exactly what it was. The belt was never tightened down. I swapped pulleys and tightened the belts tonight. I will see how it feels in the AM.

I like to see real data to back up a sellers claims. People like to say what ever is needed to sell a product all the time. I am glad to see you putting a myth to rest by putting real numbers on paper.

Thanks....
And these real numbers will jump tremendously now that I have tightened the belt down. I am embarassed as to how loose I had it.:o

You've got the hardware down, just need to work out the snags, and you'll have an incredibly powerful car. Congrats, and stick with it!
