I am in the process of installing the Holley SysteMax kit right now. I was told it should produce around 350hp. Im not sure how legitimate that is but it gives you a general idea. Remember when you get this kit you have to get more things ie. bigger injectors, fuel pump, etc.
Hope this helps. I will post more info after i am finished.

I have never dynoed under 300 hp at the wheels with the kit. They say it comes out to 360 hp at the flywheel. Are you aware of the 1.94/1.60 cylinder heads and oil consumption? I found out one month too late and my warranty was up. With less than 1k miles on kit I was using a quart per tank. Holley customer service stinks imo. If you start to use oil all of a sudden, dont think it cant be the New heads like I did. I talked to alot of people from Holley and was told they get boatloads returned for that reason.
Good luck

what about the oil consumption? I asked the question because the car i just bought has this kit in it. it has about 5,00 miles on the new motor with the systemax II. IT willl burn oil? or becasue mine has 5,000 miles on her it is ok? I don't understand the oil loss part! please explain! thanks, I better not have bought a lemon1!!

Heres the deal.. About one month after the kit was installed by a speed shop I noticed I would run low on oil. The engine was pulled and all gaskets were replaced and the kit was installed. No oil was leaking from the car. This was my weekend car and wasnt driven very often so I thought it was a fluke. Later I got so tired of it I took it to the shop that installed it and they pulled the heads and saw that the valve guides needed to be replaced- with less than 1 k miles. The cost to fix them and labor was 900$. They put my heads back on and told me to call Holley like Rick91GT did. After they ducked my DAILY phone calls,email messages, and phone messages for about 3 MONTHS.I finally got through to someone who could make a call. During the 3 months I talked to several people who all told me that they have many problems with the 190./1.60 heads. The head guy told me that it sucked that I was 1 month out of the one year warranty and there was nothing they could do. He then asked me what I was going to do, I told him if these heads are so cheap- why would I pay 900 to fix them. I told him i`d replace their heads with Track Heat and be done with it. Sorry for the length, but I wanted to give you guys the heads up on their customer service.
Good Luck

hopefully it was just a fluke. this has 5 thousand miles on it and hasn't leaked or used a drop of oil. I have heard good things from other people with this kit. Hopefully it wont happen to me though! HAve you had your car to the track at all? Curious what it does in the 1/4 mile. He said he had it at 13.2 but with no traction!
