Correct me if I'm wrong, but I believe on the 1UZ the current Autronic can do 4 ignitor outputs? That seems fine to me.
Does need an external wideband interface though.
So that motor was completely unopened? ie no new head gaskets or anything? What kind of fuel were they running? How did they stop detonation.
I was thinking about this more.. those short course drag boats see probably 3-5 minutes on boost per meet. There are like 10 meets in a season. Add...
Rod,
I just don't think you will need 20psi on a stock motor to hit 350rwkw, which is about my goal. There are 2.5 and 3 litre 1j and 2j motors hitting 325rwkw at a hair above and a hair below 20 respectively. With our extra displacement, I'm hoping for 16 to 18.
I don't see why forged...
There are stock 1UZs + copper gasket in boats pushing over 600hp, running WOT and lasting a whole season. I think with the level of built motor you are talking about (add rods), a lot more than 500hp is possible. I would think that motor would be good to high 20s psi at least.
I don't think...
Make sure not to use an acidic degreaser on an intercooler. Use a petroleum based only. I think some places bathe them in kerosene and phenol or something. Best to ask a radiator shop?
You probably lost the coolant originally due to cracks in the radiator end tanks, I would think? It's a common problem.
I'd be looking at a second hand motor, a reco radiator and some new hoses.
Pete,
will you be running a hire service on the bluetack? I have a few jobs I need to get done!
Heh heh, I know the feeling. Gradually building up more tools. Next stop, super high lift jack and weld up some 2 foot cubes to put under each wheel.
Why don't you ask Harry on ALSC, who has decompiled the code in the ECU, if the gear maps are any different? I believe they aren't. I'm just going to tell mine the shifter is permanently in "1". Apart from that, when I get boost I'm going to hand control over to an Autronic SMC anyway. Why leave...
FAT did a supercharged LPG Soarer. They used no intercooler, methanol injection, stock compression, twin Gas Research 510 or 480 carbs (not sure), 15psi. Also heavy valve springs and custom cams I think. And a motec.
