As Coops says we did think about a twin turbo setup but space is a real issue here and I doubt we could get anything of any size into the engine bay. Anyway, I've just ordered a Procharger D-1SC which may be slightly oversize but after yesterday I'm convinced this engine could run 20psi.
The D-1SC is what Bill used on his 350 Buick and it ran well: Motor Breakdown: 350 buick stock 2 bolt main block 3.830 bore x 3.85 stroke (stock configuration) All ARP Studs throughout-60-80psi oil pressure running 50w Redline stock oil pump. Eagle crank, Childs & Albert rods, J&E Pistons 8.5 comp Custom Comp Roller Cam-246/260@.50 .578/.600 112LC installed straight up. 850 CSU Carb and Hat 80/88 jetting on final pull Aeromotive A1000 regulator Race air-to-air intercooler w/ a 125 mph fresh air fan in front. Headers are 2" tubes - 21" long - 4-2-1 merge into 3.5" x 4.5" megaphone 5" long. Port IRON BUICK HEADS 290intake/200exhaust 1.6 Roller Rockers Cometic gaskets Ported STOCK IRON 4BBL INTAKE with plenium milled out 5" carb spacer 2 different ATI superchargers were used: D1 Procharger F-1 Procharger- Chevy cog adaption. Drive: 8" & 6.75" Blower: 3.5" down to 2" in 1/4" increments. 8" and 3" were the most used up to 16psi. Motor, N/A Hp and torque numbers were mid 5's NA and the graph pretty much went flat just over 5800. First Combination D-1: 838.5 hp @ 7100 674 tq @ 6000 12 psi. Boost to 15psi (overspinning blower) 881.1hp @ 6950 711.1tqe @ 6105 Second combination F-1C: 950 hp/ 731 trq. Ran it up to 7200rpm on PUMP GAS!! 20psi upper 900's with more tuning on following pulls...... on the seventh and final pull w/race gas and 20psi: 1021 hp @ 6800 808 ft. lbs. trq. @ 5750!!!
Spent most of today on the mill fabricating the mounting bracket for the D-1SC Turned a lot of aluminium into chips
While Rossco is paying with the new charger plate I'm in the process of converting the cable operated clutch pedal box in the Capri to a full hydraulic clutch system
Finally had time to mount the charger. There's still a few bits like mounting the PAS pump and then the final finish.
Sweet rotary table work you did there! Fun stuff, I enjoyed my little rotary table job I did the other day making the D-shaped dish on some Jeep pistons deeper. Very creative use of the table, good job, looks like it turned out nice! Derek
First off guys my apologies for not keeping you all updated. As usual a million things interferred with getting this blower setup finished. Well the mounting bracket is now done except for the polishing which I'll try to get done next weekend. The number one driver for the design has been the almost infinite variation of Rover/Buick setups, therefore setting the pulley alignment is done mainly with the three mounting tubes at the rear. These can be made to any length. Next up is the belt length, again there's so many variations I decided to give the idler pully a total of six predefined mounting positions. In fact just by drilling and tapping a 3/8 UNC hole the idler could be mounted anywhere that it will fit. It's even possible to fit two idlers if needed. Last night I modelled the whole thing in Fusion 360 so if there's a next time I can use the CNC router rather than the mill. The pictures below are obviously without any of the other ancillaries or a belt tensioner. Install on the car should be in the next 3-4 weeks so once its been on the dyno we'll come back with the results.
Sorry for the lack of updates but things have been slow, we are back on with the build and after having to modify the mounting bracket a few times its in and running at present, We are also playing around with water injection this time round too, Currently awaiting dyno day again hopefully later this year (once we can move around again in the UK) Heres a vid of earlier this week of fire up with the procharger
Very nice Are you aware that your steering wheel is located in the passengers side? Best regards, your "neighbor" in Denmark..
