What do you get when you slap a pair of Jeff Morys cylinder heads,a Sean Roe supercharger with the 8 LB pulley,T&D rockers,JE pistons,Oneill Rods, 50 LB injectors,two bosch fuel pumps,Arrow racing machine work, Larry Macedo's tuning help,and it's all assembled by John Edwards?????? 734 foot pounds of torque and 729.5 HP. These are corrected numbers. OH ya...93 octane.

Congratulations. It's great to see people out pushing the edge of the envelope with the Roe blower; what you learn should benefit all of us running that blower at some point. Please post a dyno sheet if you can.
Questions: 1) What compression are you running?; 2) Is it still a 488?; 3) Can you tell whether you're running into efficiency problems at high rpm either because the blower is running out of steam or the air charge is getting too hot? (I assume you're not using any form of charge cooling); 4) How long until you try a smaller pulley?

We knocked the compression down .5 still running 488 cid We never ran into an efficiency problem on the big end. We are still running it too rich at hight RPM but we will fine tune that on a chassis dyno when we have more time on engine. If any one needs any thing please contact me as needed

Those numbers are good enough to be a YELLOW Viper. If your Viper isn't YELLOW, I hereby proclaim it is honorary YELLOW.

VERY impressive. What management system are you using for the larger injectors?
Sorry I forgot to mention that we are using the STOCK 708 camshaft. I know that this is a limiting factor when it comes to making HP. I will wait and see what kind of info comes about over the next few months and change it over the winter. I should also mention that I will be putting on the Comp Coupe exhaust.
As far as a management system I am using the VEC 2 from Roe. External pumps and filter. Seems to work great.

Also you can go to "My Home" at the top and review, send, or delete any messages you may have.
ps - I can post the dyno chart if you need someone to. [email protected]
