GSX455,There is one thing that still pleagues me, why didn't you just call Pro-Filer Cylinder heads and have them make you a custom set of heads to make well beyond 1000 horsepower? Your set up is awesome. The problem I see is large cubic inches and still not enough cylinder head for it. Look at any Big Block Chevy, Ford, Pontiac, Mopar they all have aftermarket heads that breath a ton more then Buick's aftermarket heads. I have been trying for the last 6 months to get three types of heads produced for anyone that can use them, I studied Cylinder heads for the last 16 years and found out Buick is the worst out there. Everyone needs to tell Mike at TA Performance to make the heads I propose to him, Those heads would do you justice like no other. They look like Buick cylinder heads but take the valve cover off, then there is nothing of Buick there. Canted/splayed valved head. It's about getting your valve angles rt and port location rt. The current Stage heads need to be up graded like a new stage 5 and 6 and best for last a stage 7 Pro-stock style cylinder head (Dart Big Cheif head, Reher-Morrison Raptor head, Brodix BB2,3,4,5 HEADS, Pro-Filer heads. thats where you came in and need them.) Please don't think I'm dishin your Engine, Trust me I'm from Michigan orginally. They have some of the best high performance machine shops in the world their. I wish you the best of luck and post your times please. Gary McGruther
Sorry guys, no up dates on the motor yet. It has been at the chassis shop all this time. I am going to pick it up and get it back to the engine shop tomorrow. Should have an update in a week or two. Car is looking good so at least it will be deserving of this motor.
Here is the update, Main seal was melted. It was gone in less than 30 sec. of warm up time. no design issues found in the block or on the crank. Talked to Dailey, was told no Viton seal will hold up to this high of a constant vacuum. They sent us to a suppler that makes a Teflon one piece split seal. The seal has been installed and the motor is ready to dyno, I just have to find time away from work to get over and run it.
Wayne, not to dever you away from anyone but, try calliing Mike Moran over Taylor,Mi. Moran Racing engines. They can make any seal for you out out some wicked seal materials they have their . Mike is a good man to get to know
Very nice engine and HP numbers! Looks like there will be enough high HP number Tomahawk block that can be tested next year! Awesome build! Have fun with it and show the Brand X members that your Buick can haul ass!
Update: The new design seal worked just fine. However it revealed a issue we were not able to see last time due to the bad seal. We need a larger drive pulley on the pump. We are getting over 20 inch. of vacuum at ideal, and only 15 inch. at rpm so we need a new belt and pulley to spin it up so we are at 23 to 25 inch. at rpm. Had the 3 step headers which will be on the car available for this run. Motor made 1019 HP @ 7800 peak and 801 Lb Ft of Tq @ 6300 never went lower in the RPM's to find Max. 6300 could be max just never started a pull below that. Its at 1000 hp by 6900 RPM and just flat,to over 8000. At this point, the next time this thing fires, it should be in the car, and begin testing on the asphalt Dyno.
Wayne, That's the picture dreams are made of. The headers look great! Hopefully all your patience and preparation pays off with some nice timeslips. Looking forward to seeing you at the track.
Thanks, Any time if there's money involved. Did I say 1019? I must of fat fingered that, I meant 101 that 9 was a mistake. LOL
Remember to put a GoPro camera in your racecar the first time you fire this beast off down the strip - we all want to see and hear what will be going on:3gears: This is so exciting to see and would be a dream to put together. My hats off to you for completing the build.
Very nice Wayne. I was wondering do you know how much more power is there in that amount of vacuum. I was only seeing 8 inches when we ran the wagon. Maybe I need to upgrade. Your engine is a work of art. Thanks for sharing.
