Wow. Just caught up on 180 pages in the last few days after not visiting Sau for ages. Still an awesome thread. Some excellent improvements and results Stao!!

Finally getting my SS2 off its run in tune soon and adjust for the change in cam timing. I'll post results when I get them.

What did you mean by 'run in tune' ? I've got a SS2 that's going on soon as well

I didn't get to see the tuner the day I dropped it off. He saw it had a new motor so only set it about 17psi and not much timing. Time to put some more hurt on it now I've dialled the cams and got rid of the lag it initially had when cams were retarded.

Some updates, This is an internally gated prototype that I've been working on few weeks, the goal is 370rwkws on E85 fuel with excellent drive ability, internally gated bolton to factory RB's manifold, dump and all lines.

My final result was 365rwkws @ 23psi E85 and 330rwkws P98 @ 22psi. 20psi was reached at 3800RPM, while made over 200rwkws @ 4000 using either fuel. This is probably the highest power any one has every made using a bolton turbo. I'm very happy with todays results.

Anyone remember when the SS2 reached 20psi ? It was a while back and couldn't find it. Currently can't decide between the SS2 or new ATR45

That might I've been my dyno results im running 21psi internal gate 297rwkw on p98

4000rpm give or take a few hundred depending on mods and turbo specs

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
