Follow Ups	I Have Heard Some Bad Rumors about Lightened crank pulleys.. - 5liter-eater 11:16:38 02/25/03 Absolutely, 100% YES, they are the worst thing EVER!!! (n/m) - my91z 11:19:41 02/25/03 Every last person who has used one has hda their engine blow (n/m) - my91z 11:20:14 02/25/03 They are SO bad oil will shoot out of your engine the > - my91z 11:20:38 02/25/03 thats enough girly man (n/m) - TARGETZ 12:34:23 02/25/03 Uh-huh.... a bit late on that comeback, eh?

Ask AK[zip] (n/m) - niXit 11:43:26 02/25/03 Where did you get that from? - AshsZ (FABio) 11:50:48 02/25/03 umm...haters? I don't think so - aliaZ 12:03:23 02/25/03 I wasn't pointing fingers.

My ECU upgrade that is the same kind of upgrade as JWT - AshsZ (FABio) 12:46:07 02/25/03 what about dual MAFS? - aliaZ 12:57:28 02/25/03 I will have a dual-intake setup which will not require - AshsZ (FABio) 13:25:41 02/25/03 I'm more interested in the benefit of running... - aliaZ 13:39:16 02/25/03 Dual-intake splits the air between two filters so you - AshsZ (FABio) 13:42:00 02/25/03 ok I misunderstood (n/m) - aliaZ 14:35:17 02/25/03 Why not do a MAP sensor...much better for high Hp... (n/m) - Kyle(Houston) 13:39:32 02/25/03 The ECU uses a VE calculation to determine engine load - AshsZ (FABio) 13:44:33 02/25/03 Everything I have read, has said MAP is very innaccurate. - niXit 14:13:23 02/25/03 Hmmm - Marshall 14:24:14 02/25/03 Any race car I have ever seen has had a Map sensor---> - Kyle(Houston) 07:40:48 02/26/03 Yeah, having one for 85K w/ 205K on motor is WAY unreliable. (n/m) - my91z 11:49:27 02/25/03 You also have an NA. (n/m) - AshsZ (FABio) 11:52:03 02/25/03 Which sees redline everyday it is driven...your point is? (n/m) - my91z 11:53:53 02/25/03 Its not specific to RPM - its specific to torque. - AshsZ (FABio) 11:57:25 02/25/03 I agree with this (n/m) - aliaZ 12:04:39 02/25/03 I don't buy it.

(n/m) - AshsZ (FABio) 12:22:02 02/25/03 I see your pattern, "yup, ok", I like that new you =) (n/m) - ZEngineer 12:27:26 02/25/03 Hmmmm... My engine has a little shimmy between 2200-3500>>> - Bobby12many 12:05:06 02/25/03 I know what you're talking about... - ZEngineer 12:07:50 02/25/03 Damn does it bother me... (n/m) - Bobby12many 12:14:19 02/25/03 Mine does too - Marshall 12:21:50 02/25/03 yes, but mine's a separate issue - ZEngineer 12:30:30 02/25/03 I know what you are talking about>>> - Bobby12many 12:36:33 02/25/03 yes, make it stop Bobby, MAKE IT STOP!! =( (n/m) - ZEngineer 12:42:37 02/25/03 Oh, I will. :) New DS, Diff Bushings, Trans Isol Mount go on - Bobby12many 13:51:50 02/25/03 I have a great diff bushing writeup here if you need it (n/m) - ZEngineer 14:05:09 02/25/03 If youre referring to the one Mike(my91z) wrote, I got it :) - Bobby12many 14:16:38 02/25/03 yup, that's the 1. You're all set I guess, good luck (n/m) - ZEngineer 14:25:50 02/25/03 Sounds exactly like my car... Exactly (n/m) - Bobby12many 12:32:43 02/25/03 Check your U-joints, my Jeep does that when they R going out - my91z 12:50:57 02/25/03 that is possible. - Marshall 13:29:39 02/25/03 dont be surprised if as you're checking it, - ZEngineer 14:10:01 02/25/03 You're probably right. - Marshall 14:26:07 02/25/03 You forgot the key words, was it a tested on a VG or - Spongerider (Now PFC) 12:17:38 02/25/03 Shorter crank only means the resonant frequency is higher - AshsZ (FABio) 12:33:21 02/25/03 Nope... - Spongerider (Now PFC) 12:48:15 02/25/03 Ok. (n/m) - AshsZ (FABio) 12:50:43 02/25/03 that's overly simplied - Marshall 13:10:15 02/25/03 It is possible to move the resonant frequency out of range? - Marshall 12:55:07 02/25/03 In a good design, yes but > - kuah@splparts.com 13:05:30 02/25/03 Nope. Harmonics allow lower frequencies to amplify higher - AshsZ (FABio) 13:06:13 02/25/03 Re: Shorter crank only means the resonant frequency is higher - SactoTodd 12:55:35 02/25/03 An ant can carry many more times its own weight.

I don't see your point? The "damper" is still tuned> - my91z 13:14:31 02/25/03 I'll reply with Kuah's answer- it doesn't need to be tuned. - Marshall 13:24:38 02/25/03 Just like shocks on a car don't need to be tuned 2 the mass? - my91z 13:28:37 02/25/03 The shocks on a car should just dampen anything - Marshall 13:36:44 02/25/03 Actually, the damper compression and rebound, but >> - my91z 13:51:00 02/25/03 it's possible... - Marshall 14:13:46 02/25/03 flywheels do nothing to dampen harmonic vibrations - aliaZ 13:08:40 02/25/03 And I said any of this where? >> - my91z 13:17:39 02/25/03 It would actually lower the tortional flexion because - AshsZ (FABio) 13:09:19 02/25/03 Did anyone actually read my post? - my91z 13:31:18 02/25/03 Yup. I answered. (n/m) - AshsZ (FABio) 13:38:30 02/25/03 I did. - Marshall 13:46:21 02/25/03 That is how it operates. It dissipates the vibration - AshsZ (FABio) 13:55:34 02/25/03 You need to look at it in the relative oreders of magnitude> - my91z 14:01:36 02/25/03 Yes I understand that. - Marshall 14:19:55 02/25/03 Such dampeners do not need to be "tuned" for a frequency - kuah@splparts.com 13:10:22 02/25/03 You are re-iterating what I said.
