My Almost-daily Journal |
|
| About I love trying out new things, especially when it comes to internet technology. I never really kept a journal, but it's something that I've always wanted to do. Now, everybody will get a chance to look inside my twisted, and somewhat-warped mind.
I've also subscribed to Audio Blog, so a few times a week, I'll leave actual voice blogs. Very cool!XML Newsfeed  |

Wow! 97.1! (Scanned @ Decoma)97.1 FM How awesome! I called in on talk radio 97.1 FM Greg-and-Michelle and I was actually on the air for a long time! I'd say at least five minutes! Very cool! posted by Dino at 10:49 AM (permanent link) (0) comments Thursday, July 08, 2004
4.7 HO V8 vs. 4.7 standard V8 Wow. There sure are a great deal of differences between the standard 4.7 and the HO 4.7. I was pretty impressed! Even its "track" stats were impressive (I've also seen 6.7s 0-60 on another site): Speed: 0-60 mph: 6.9 (Motor Trend) 0-62 mph: (0-100 km/h): 8.3 (DCX) 1/4 mile / speed: 15.4 / 86.6 mph (Motor Trend) Top speed (w/ limiter): 118 mph Top speed (w/o limiter): 128 mph (DCX) This link was pretty useful: Jeep Grand Cherokee WJ - 4.7 HO Intake and Exhaust system Summary of HO engine feature differences (Compared to standard 4.7 liter engine): 1. Camshaft - custom profile lobes (designed for increased performance) 2. Connecting rods - modified, with floating wrist pins (vs pressed-fit pins in standard V8) 3. Crankshaft - forged steel (vs cast iron in standard V8) 4. Crankshaft damper - unique to HO 5. Cylinder heads - different shaped combustion chambers (for improved airflow) 6. Exhaust tip - chrome (2002 models only, decontented for 2003 models. Available only as a one-piece assembly with muffler) 7. Fuel injectors - higher flow (+3.3 lb/hr) 8. Intake manifold - modified (shorter runners) 9. Intake - low-restriction intake system (different resonator, air filter, air filter hose and housing) 10. Knock sensors - two, stereo 11. Main bearings - tri-metal (vs bi-metal in standard V8, designed specifically for the HO engine) 12. PCM calibration - unique programming 13. Pistons - dome shaped for increased compression ratio 14. Spark plugs - platinum tipped 15. Valves - unique exhaust valves (same lift as standard V8) 16. Valve springs - upgraded valve springs (intake & exhaust. Larger diameter wire and more coils) 4.7 HO Specifications General: Camshaft: Custom profile lobes (designed for increased performance) Compression Ratio: 9:7.1 Crankshaft: Forged steel, with custom damper Cylinder Block: Cast-iron block with modified aluminum alloy heads Cylinder heads: Different shaped combustion chambers (for improved airflow) Displacement: 4.7 Liters / 287 C.I. Engine type: 90° SOHC V-8 16-Valve Engine Power (SAE net): 265-270 BHP @ 5100 RPM Engine Torque (SAE net): 325-330 LB-FT @ 3600 RPM Engine Bore x stroke: 93.0 mm (3.66 in.) / 86.5mm (3.40 in.) Firing Order: 1-8-4-3-6-5-7-2 Injectors: Flow = 25.8 lb/hr @ 49psi Knock sensors: Two (Stereo) Lead Cylinder: # 1 Left Bank Main bearings: Tri-metal construction Manifold, Intake: Modified (shorter runners) Oil Capacity: 6 Quarts, 10W30 recommended Oil pressure: At curb idle: 04 psi min. @3000 rpm, 25-110 psi RPM Engine speed, maximum: 6000 RPM RPM Engine speed, tachometer redline: 5700 RPM Spark plugs: Unique platinum-tipped spark plugs. Type SPRC7PYCB4, 0.40 in. gap Pistons: Piston diameter: 92.975 mm (3.6606 in.) Piston material: Aluminum Alloy, Symmetric pop-up design (for improved compression) Piston weight: 383.5 grams (13.52 oz.) Piston pins, type: Full floating Piston pins, clearance: 0.010 - 0.019 mm (0.0004 - 0.0008 in.) Piston pins, diameter: 24.017 - 24.020 mm (0.9455 - 0.09456 in.) Valves: Valve system: Chain-driven SOHC, 16 valves, hydraulic end-pivot roller rockers. Unique exhaust valves Valve springs (intake and exhaust): 7.30 coils, 4.77 wire diameter Intake - Opens (ATDC): 3.0° Intake - Closes (ATDC): 233.0° Intake - Duration: 236.0° Exhaust - Opens (BTDC): 235.0° Exhaust - Closes (ATDC): 15.0° Exhaust - Duration: 250.0° Valve Overlap: 18.0° Valve lift, Intake (at 0 lash): 12.0 mm (0.4724 in.) Valve lift, Exhaust (at 0 lash): 10.90 mm (0.4292 in.) Valve lift (zero lash): Intake 12.0 mm (0.4724 in.), Exhaust 10.90 mm (0.4292 in.) Speed: 0-60 mph: 6.9 (Motor Trend) 0-62 mph: (0-100 km/h): 8.3 (DCX) 1/4 mile / speed: 15.4 / 86.6 mph (Motor Trend) Top speed (w/ limiter): 118 mph Top speed (w/o limiter): 128 mph (DCX) Fuel: Fuel Economy mpg (EPA est., City/Hwy): 14/19 Fuel requirement: Regular unleaded, 87 octane. For maximum performance, Unleaded premium, 93 octane. posted by Dino at 10:46 PM (permanent link) (0) comments Wednesday, July 07, 2004
