    Valve springs too strong?

    I always appreciate most of yours guys input and thanks to many your unfortunate accidents, others, including myself, can learn from and even prevent. It sometimes seems odd how a person can view something and interpret it differently. But I suppose such is life with its continual mistakes ad...

    Valve springs too strong?

    Rod Im not arguing with you but how would a single cotter groove be stronger than a 3 cotter groove? Enlighten Me.

    Valve springs too strong?

    I would like to use the orginal cams and new Bucket lifters. One of the main reasons why i like the Mercedes valves over my standard ones is that it has a 3cotter groove. Ok hows this for a simple comparison; When i was stripping the 16v head i used a socket and a hammer to remove the upper...

    Valve springs too strong?

    I also thought as much. Someone told me this story and he reckons that is one of the main purposes of a billet shaft. So this got me thinking and then worrying. How would one measure the resistance of a Valve, I mean what machine would it be?

    Valve springs too strong?

    I have a 16V cylinder head that I'm trying to fit Merc valves to. The Merc Valve Springs are slightly longer, smaller in diameter and are much stiffer, than the orginal springs. I would like to know if it possible to use these springs with the hydraulic bucket lifters and not break the camshafts...

    Twincharging with Screw-Type SC instead of Roots

    Pat I can see where you're coming from in that they are just two gears costantly in contact and motion, and that Normal Manual Transmission oil would work. If I Were to use this then i would just change the oil regularly. I'll try to find i similar rating to those two types of oil, but if i...

    I Know what you mean about getting blown by facts. Um I think they wanted the oil filtered because they were using tiny oil jets to spray oil on the gears. Possibly they didn't want them getting blocked. I'll have a look to see how hard it is to adapt a oil jet system to the charger.

    Twincharging with Screw-Type SC instead of Roots

    here's the response straight from Steve Padfield of Vortech Engineering: "[Vortech's] maintenance-free lubrication system uses engine oil that is pre-filtered and injected directly onto the drive gears. We chose this configuration as opposed to a `self-contained' setup because engine oil...

    Twincharging with Screw-Type SC instead of Roots

    I need to replace the oil in the gear section of the supercharger, unfortunately after searching I can't find what type or viscosity ,mainly the latter ,to use can somebody please suggest a type of oil. Somebody suggested Diff Oil like a 85w 90. Thanx

    Twincharging with Screw-Type SC instead of Roots

    I'd have say that this thread has been very fruitful. But the way I've decided to do it is way Warpspeed suggests, Sc then Turbo with two wastegates controlling the boost. And Possibly Using Two Intercoolers, the one might be a charger cooler. I'll use the Sc first and how it behaves then i'll...

    If one was to intercool the air after the turbo before entering the supercharger would a liquid charger cooler after the supercharger suffice.

    Twincharging with Screw-Type SC instead of Roots

    Thanx Pat For Answering My Q's If I Were To Add The SuperCharger First Run With It And See Where The Power Comes In And Out (And After That Add The Turbo) My Q Is Do I Need To Add A Dumpvalve To The SuperCharger Plumbing, I Don't Think So Cause The Supercharger Is Belt Driven. Then If I Had...

    Twincharging with Screw-Type SC instead of Roots

    I Have Read The Thread Again And Yes I Did Miss Plenty Good Points. Sorry About The Caps It's Habit More Than Anything. I Must Admit Im Still A Junior To The Whole Supercharging Idea, I Know Plenty About The Turbocharger But Using Them Together Is New Grounds. My Only Worry About Running The...

    Twincharging with Screw-Type SC instead of Roots

    Yes That Is A Method That Could Work. There Are Three Ways To Go About This I Suppose. Turbo Before (Feeding) Super Parallel Super Before (Feeding) Turbo I Was Thinking More Along The Lines Of Going Parallel With The Super Working Until Say 2000Rpm Then Disengaging The Clutch Of The Super By...

    Twincharging with Screw-Type SC instead of Roots

    The Thing Is I Have Both A Mercedes Supercharger (Screw Type) Off A C180K And A Mitsubishi Turbo. It Was Not My Intention To Use Both On The Same Car (1700cc Motor) But The Supercharger Does Not Have An Electro-Magnetic Clutch Which Would Be Ideal. Short Of Designing One Or Adapting Another I...
