John Csordas Any block fill in your son's engine? My I ask why you elected not to go with a block girdle? Thanks
No block fill on the last one but did have if half filled on the previous one. We did not girdle simply to keep the cost down not knowing if the blocks could hold the pressure. We have the halo girdle which it all you really need in my opinion. Aluminum rods to keep the weight down & you are good to go. The last block we lost at BPG this year thru the traps at 140mph with 5 lbs of boost was due to a thin wall & it cracked which really had nothing to do with BOOST. I should have not used the block but was pressed for time & it cost my son alot of extra money. Right now we have a stock 455 Stage 1 iron headed motor back in the car so he can really cruise the streets with my 2 year old grandson who loves this car. We will have the Stage 3 motor back in for next summers racing events. Remember this car weighs 4000lbs & it fully automatic & is NHRA certified to 7:50. It has a back seat with baby seat but no heater or radio but trust me it is warm enough with the 4" exhaust & 2 sets of mufflers.
Bob, Those are the Fel Pro Performance gaskets, that have a flattened copper wire in them. About $65 apiece, but a very nice gasket. We talked about all options, and since this thing was set up for around 10psi, not the 16 the pulley's ended up making, we felt that the composition type gasket was the best choice, considering cost, water sealing and compression sealing, in a street/strip application. Second time I have used these gaskets on either a high compression or boosted motor, and I am impressed. JW
I agree with Jim on those gaskets we have been useing them on most of high perf builds for a couple years they work really well. Never tried them on a boosted app before but maybe on one of the next ones.
Jim, Bob or John, To install a Supercharger of this kind, what kind of dollars are involved? Does the bracketry come with the parts or does it have to be custom made? Thanks
John, Here are the components of the kit I used.. http://www.vortechsuperchargers.com/product.php?p=159 http://www.vortechsuperchargers.com/product_variation.php?pvk=67 http://www.vortechsuperchargers.com/product.php?p=25 http://www.superiorairflow.com/carb-hats/unpolished-aluminum-4150-series-gasketed-carb-hat.html Cog belt drive is a custom piece, it came from these guys, not sure of the actual cost, as this was delivered to me in a kit, bought by my customer, from a boardmember who had ASP make it for him. I would Imagine it would be somewhat more expensive than their $600 in stock 5.0 Mustang stuff. http://www.aspracing.com/index-2.html The only thing that has to be custom fabricated, is the plate that holds the supercharger bracketry to the Buick head. Also, we have an this Alky system.. http://www.alcoholinjectionsystems....ater-Methanol-Injection-Kit/product_info.html JW
Looks like a great motor! JUst wondering on how your going to keep it cool!!!Had a lot of problems keeping my 464 cool in my 65..
I never had a problem w/ my 464 so we will see. I had a brass four core radiator and just switch to a custom be cool unit I had them build for the S\C motor. I will say my clutch and seven blade fan did a better job cooling then my twin 11" spal fans but the temp never went over 200 in the Texas heat. I also had my trans cooler in front of the radiator w/ 4000 Rpm stall. Regards,
Hey Jim, Awesome build! Just one question, why did it go so lean on the top end? Did fuel pressure drop out? My experience with the Holley Carbs, is that it richens up on the top end.
Got to hand it to you Jim, turned out great! I've got to ask, did you have any trouble with crank case pressure? When we did the F1 on Gregs car after driving for a while, "a little scary" the crank case would build enough pressure to blow the seals. Then it becomes a fog maker until we fix the gaskets again. We have two vents in the valve covers. I'm trying to talk him into a belt driven vacuum pump. Have you ever experienced this problem? These things can really push some air. Once we fired it up with the Hat off, it cleared the benches of all small parts and a couple small children.:laugh:
No, boost referenced fuel pressure is listed on the 1000 HP dyno sheet, as "Injection P".. with a base of 8 lbs, it was 26 or so at 6300 and 16+ pounds of boost.. It's called "trailing lean" and common for blow thru carbs. It leaned out due to the carbs inablity to pass fuel thru the front power valve circuit. We did increase the power valve passage from .075 to .093, per instructions from Kevin at CSU, and that helped, but we still have to do some final tuning on it, when it goes back to the dyno with the correct pulley to make the 10-12 psi that the build was targeted for. I didn't want to get too far into the tuning, till we get the right pulley on it, and the pump fuel in the motor. It was on 110 octane on the dyno, with the alky system, to prevent us from detonating it. JW
David, No, we had no problem with crankcase pressure, I ran two breathers in the cover, and a PCV valve from a Turbo 3.8 L motor. JW
".....with a stock block, oiling system, and crank, my butt was puckered about as tight as possible.. :laugh: " And they say it can be done............:eek2:
