We found the end of power at 23.5 psi. These are the last few pulls adding timing.

Precision 6766CEA ball bearing turbo. We are also working on a prototype exhaust housing " variable vane" to bring down the power band.

Ported head, 270 cams, Full Race with my waste gate setup on it I like heat away from the intake side, factory intake 1000cc Injector Dynamics , all the normal and a few tricks. I'm going to put another intake on and see what happens. And try some 110 cct.

Here's a vid for fun of a 2nd gear pull. Dyno tune was done in 4th funny how a tune changes in second.

it would be hitting differet load points in 2nd on the dyno unless running a really slow ramp rate

Not a bad output for the boost and fuel.

Looks laggy though 23psi at 5750rpm and only revving to 8000rpm?

What is is that attached to the rear housing of the turbo?

Where you looking/working out boost?

Just going off 90mph where it looks like everything starts to happen... 90mph = 145kph = 5180rpm (300rwkw)

I can't exactly remember what speed 4th gear pulls, but that RPM doesn't seem right to me. That would make 4th gear top at 195KM/H at 7000RPM...

If you are sure that 145kph is 5180rpm then this graph is almost identical to my graph. Same response, same power.

Well not 100% sure, just using Paulr33's old RPM calculation.

Could well be wrong! :)

By those same number 142mph / 228kph / 8150rpm

Can't remember what 8000rpm is in 4th on my car off the top of my head :wacko:

Me either - cant remember exactly what it is.

Piggaz is good with gearing, enlighten sir paul :D

8000 RPM on our car is 235 IIRC.

Oh. I just had a search around and found a word document I have saved over the years.

145 kp/h isssss... 4850 RPM according to this.

3000 RPM = 85 HP

3500 RPM = 120 HP

4000 RPM = 160 HP

4500 RPM = 240 HP

5000 RPM = 415 ish HP

5500 RPM = 470 ish HP

6000 RPM = 545 HP

6500 RPM = 610 HP

7000 RPM = 660 HP

7500 RPM = 700 HP

7900 RPM or so = 733 HP

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
