I just got back from Jersey where the guy was supposed to put it back on the dyno, but you know how that goes. It will go back on at 8 tonight.I wasn't waiting. What I got a chance to see was where the dyno was and who was doing the management system. Check this out: http://www.idaautomotive.com/index.htm The guy is known as Bob Billet (Ida) and the stuff he makes is unreal. Matt from Finishline did the install, and Bob is doing the management. You should see the Tucker he's got with a 25K billet rear bumper!!!He has so much stuff, I didn't know what to look at first~billet wheels, valve covers,grills, calipers. Everything he need, he makes. I asked about a copy of our grill in aluminum and said how much. He said with polish same as the M&K. He said he could also make the M&K out of aluminum!~only catch, 20 pieces at a time. Now about my car. It looked dirty, but I knew it was glad to see me! The blower is pretty quiet except for a rattle at idle. Matt felt the the belt was slipping, so he put on a shorter belt, and I now have 10 lbs of boost. The installation is clean, but its real crowded underhood. I didn't take it for a ride and will wait till all is finished. There are still some hoses to be moved and some odd and ends to be done and I said keep it till its right. Another day or two. I have some pics of some of the things in Ida's shop, but they're too big to post on POA. Any one interested?

I have read every one response to this thread. I have known Art Whipple for many years he builds a great product. He is known for his Chevy applications. There are differences in a roots style supercharger and centrifical. They both move air but in different ways. The roots style do make boost at lower engine speeds but produce hotter discharge temps. The roots style tend to fall of at higher rpms. The centrifical supercharger is more lenier and produces lower discharge temps. However the problem with the Prowler is that the engine compartment is tight. That means its hard to relieve the heat from the engine compartment. The space to mount a supercharger is very limited and tight, so it is hard to build the most efficient system. We were in contact with this person when we first started our supercharger project and he was experiencing the same problems we were. However we have been supercharging cars for over fifty years. Good luck with your project if we could be of any help please feel free to contact me. ------------------ |

Bob, thanks for your input, I'm sure you know more about superchargers then I do. The bottom line is that i'm putting out more power at this point, using less boost. The torque is way higher and starts from a lower point. I'll get a chart posted as soon as we have a completed project. This is relatively new project and I'm sure the problems I have now will go away, or at least I hope so. I dont knock your unit as it has been proven to reliable, but I just wanted to try something different as I've said before. We're using your inlet tubing between the throttle body and blower. Space is tight, but everything fits. It's just a shame we had to scrap your left side header for a custom made one to give blower clearance. They're really nice pieces. ------------------ This message has been edited by butchcee on 09-06-2001 at 02:40 AM |

The Whipple boost comes in so fast that that Matt is having trouble keeping on the inlet hose. This is why this type of blower makes so much low end power. The drivability was reprogramed and no more hesatition. At the final pull, the hose split. This has happened with the high pressure Paxton systems also, as the rubber elbow is made for suction, not pressure. We're going to solve the problem for good by welding on an elbow directly to the throttle body and use high pressure hose. Matt has received the forged pistons for the next Prowler project and it appears that the owner wants more power then I do, so it will be interesting to see how far this engine can be taken. Watch this guy folks, he's on a mission  Also, Bob at Ida has an idea for a louvered hood and side panels to draw air from.------------------ This message has been edited by butchcee on 09-06-2001 at 02:41 AM |

I got the final dyno run using the whipple. As you can see, the run starts at 3200 because he uses 3rd gear only for the pull. This is with a little over 9lbs of boost.  ------------------ |

Looks sweet Al. I'm happy for you. Except for the boot blowing off. I have the same trouble, just got a new one and being VERY careful with it. Any idea when you got car back to run it? ------------------ |

I wont BS you JD. I just found out that at the end of the last run, it threw the belt, which means that Matt has to work on a different tensioner to keep it on and then another dyno run . The elbow problem is fixed with the welded on 90. To be continued !!! Do they sell snows for 20 inch rims? ------------------ |

Al, I threw a belt about 7000 miles, I think its all in the inital allignment. I have more trouble keeping the rear boot on car. And it tears so easily. I spent about a hour to adust the ductwork in hopes this new one will hold. Sounds like you still have work to do, keep us posted,, STUD MAN??????????????? ------------------ This message has been edited by jd2ksilver on 09-09-2001 at 12:53 PM |

Matt thinks that the belt needs retensioning after the initial run. He tightened it up and is going for a cruze today. Check out the initial torque this thing makes. The torque is the top line going down and the HP is the bottom line going up. A tire shredder for sure!!I think the HP and torque spike at the end of the run is the stock ECM shutting the fuel down at the redline and just running on the piggyback system. I think we're running too rich with a 12-1 air fuel ratio and we neeed to lean it down a bit.MORE POWER!!!!!! ------------------ |

I got this e-mail this afternoon from Matt's wife. What do you think this means?!!!!!!! I cant wait. Hope the tranny holds up! Matt just called me and asked me to email you to let you know that he is still at Bob Ida's shop. He was VERY excited and wanted me to let you know that he is making INCREDIBLE numbers!!! ------------------ |

OK, here's the info I just got. Matt spent all day and did 16 dyno passes on the car. He had to put a second bypass valve on the blower to limit the boost. He was scared to run the engine at the level of power it was putting out. We ended up running only 8 lbs of boost. The drivability problem is programed out~no more hesitation at the start of boost. The engine only makes 303 RWHP but with 370 Ft Lbs of torque at 3500 RPM. It hazes the tires all through 1st and 2nd with no power brake. He's been in lots of race cars and he says it feels like a 150 nitrous shot when you punch it. We ended up with an air~fuel ratio of 12.5-1. The bypass's are set up to give 10 lbs of boost initially, and then settle back to 8 lbs. He says its an animal~I think I'm gonna like it. Clean up and little details and back to me before the end of the week. ------------------ |

Thanks John, I forgot to mention, Blower temp was 125, and inlet air was 103~108, so this unit doesnt heat up the air very much. I'll be working on a system to pull outside air from the side panel. ------------------ |

Al, way to go! By the way, there's a bunch of us Paxton types that would love to find a good way to get cool fresh air to our blowers, so we're now looking to you as the pathfinder. |

Rich, contact Bob Ida at the e listed in this thread. He's the one going to come up with the plan for my system. Makes no difference to me whether I draw from the left or right side of the car.The plan is for the grill to be billet with an airbox inside feeding the blower. The more we get on this project, the less expensive. ------------------ |
