Project Supracharger

The plan for today was to confirm the new belt is the correct length, shim the top idler true and trial fit the N/A throttle cable to the bespoke linkage.

 

But have chosen to pass on freezing my previously frost bitten fingers and dropped nuts disappearing into the snow.

Good news; I final fitted the cable/bracket/ramp, everything lines up nicely and just goes in. :)

 

Bad news; The N/A cable is too long, so will need to make another. :(

Good news; I have shimmed the top idler pulley to run true. :)

 

Bad news, the new belt is still too short and have found the steel OE idler pulley on the tensioner is about 25thou out of round, see the chatter it's causing @ 9 seconds. :(

Thank you for the compliment. :)

 

That's typical progress, doing two jobs allowed me to find that there are actually three more jobs to do to get to where I thought I was going to get to. :think:

 

I don't like the gas strut tensioner either, so making an adjustable spring loaded Mk2.

When he has this running it's going to bed nuts. Highest powered stock compression NA running on the forum I expect. Aiming for 14psi aren't you david on stock HG?

 

Gonna be evil... with stock compression so no low comp lag and a charger kicking in low, this thing is gonna be nuts.

 

Are you going to be doing ride's at Pod David? :)

H.T. 'Force' is strong in me :superman: and leads are off the list.

 

 

Before: Coil to distributor not long enough and 3 plug leads too long

 

attachment.php?attachmentid=146999&d=1330268374

 

After: The shortened plug leads lay much better

 

attachment.php?attachmentid=147000&d=1330268374

 

Coil lead replaced with longer and rerouted to clear supercharger snout and throttle mechanism

 

attachment.php?attachmentid=147002&d=1330268374

 

Tight & tidy on the pre 92 V6 4Runner cap makes space for supercharger snout

A couple of jobs off the list posted a couple of posts ago and a few hard-earned bits & bobs & things & stuff compiled again. :)

 

Victims hunted down for the adjustable spring-loaded secondary belt-tensioner I can see in my minds eye. :think:

 

M10 male and M8 female rose-joints found on ebay

A likely looking 3mm spring found on ebay too

M16 threaded tube from ironmongersonline

M16 half-nuts from local Ironmonger

Long M8 bolt found under Kerons' bench

Stainless-steel billet-end from local engineers scrap box

(Need a couple of O-rings)
