1972 MS75 Toyota Crown Hardtop-1FZ-FE turbo

In reality however, if even I get within cooee of 1500hp I'll be over the moon.

Yeah for a bit... then you'll want more

When injecting into the compressor housing do you have any problems with it eating away at the comp wheel?

100% methanol and no intercooler......now were getting serious Sean!!! I love this car but maybe you should take up TKs offer and run the gear in a lighter car??

nah its in mist form.....I run two indy blues infront of the turbo and have no dramas. The wheel is turning so fast that the stuff just slips straight off. If you're concerned just spray some WD through the comp wheel after every use. I don't think its a big issue though.

Is this thing still a street car?
We're starting to talk similar power and probably performance to Dale's VT.

I think Sean intends to keep it rego'd & street drive it occasionally.
So I guess you'd still call it a psuedo street car.

Bernie - the Fiat is way to short for 1500HP, it'd be more than a handfull, it'd be lethal - I may end up putting either a single turbo chev or maybe 2J in it, but not for a few years.

To be honest, if I was less financially responsible than I am (and that's a interesting concept in itself), the car would have been dropped off at a chassis shop and treated to a proper 4-link conversion ,shortened 9 inch, tubs and 12 inch wide slicks, then fitted with a $6000-$8000 powerglide.

In reality though, it'll all have to be done by me bit by bit. I'd like to keep plates on it and cruise about occasionally, as a track for SA is still a while away. If I can fit a good cooler on it once the engine is recessed and the full front end trim re-instated (I have a full series front end coming so it looks like a car again), I will to allow some occasional street laps. (but methanol cooling will still be fitted also-I might just go for methanol cooling and a big fuck-off PWR Barrel, but TBA once the motor is recessed and I know how much realestate I have.)

The BW diff I put in will remain whilst the motor package is sorted-but after that I'll tub it and go narrowed 9-inch.

As for the erosion of the comp wheel, Alex is asking about actual liquid erosion-which can occur with water. I'm not sure about methanol, but I was intending to inject into the scrollto make mounting of the injectors easier and avoid any potential problem. (although bernie your info that it's okay is useful)

Some days I want to drive it again, and some days I don't, but I'm sure that once the new rack+pinion steering and decent brakes are fitted, along with getting the motor moved back in the car will make it a much nicer drive.

You can see how my 2 injectors sit in the front cover. I also run water injection infront of the turbo too. I have a couple of nozzles in the air cleaner and 2 along the compression pipe also.

[Supercrown]

I see Bernie-I hadn't realized you'd gone for no cooler at all on that car.

Interesting.

How well does it work? (I notice you ditched the barrel cooler-that kills that one off for me then too)

Have you done any testing on intake temps vs volume of methanol injected?

Considering the fuel system will be 100% methanol with an aeromotive pump, I won't need any separate pumps or anything-just tee into the main line and have the SM4 do the switching of the injectors. (probably a couple more Indy Blues I guess)

[bernie-rx7]

yeah thats what I'd be doing. rule of thumb with methanol double the flow, especially if you're going to run it on its own. I just run water and methanol injection for the cooling factor mainly. I obviously have 2 injectors in the front cover and 3 direct port 1600 indies. Plus 6 nozles that run water injection via a variable load cooling mist reg.

I originally experimented running water through some bosh mercedes benz injectors with some good results but in the end couldn't prevent the inevidable rusting up of the injectors as much as i tried. I ran a 8/10 PWR barrel for a while. It seemed to really imped the throttle response IMO but it was pretty effective at keeping stuff cool. Admittedly i didn't run the water injection with the barrel, probably get some even better results. The lack of throttle response was the contributing factor for me giving it the boot though.. The response improved out of sight since ditching the intercooler. I was running a big turbo though.

At full noise I run approx 50/50 pump fuel to methanol. inlet temps usually stay <35-40 degrees... which is OK. I will get the chance soon to fool around some more with the methanol & water injection to reduce the temps even more. The methanol cools well on its own but seems to be complimented with the water injection and vise versa.... methanol for power, water just for cooling and keeping the engine internals steam cleaned!!

I have a second computer that runs the methanol. When the methanol tank is empty a light comes on the dash telling me to slow it down and switch to the lower boost map. The water injection lasts for a while so street driving without methanol on a lower boost setting the car still remains quite cool.

I had engine analyser pro running, so I figured I'd do a quick sim of the 1FZ using the flow figures for the head with stock valves, 9.5:1 comp on methanol & a guesstimate of the cam specs (can't remember them).
I don't think I've got the turbo specs right, it maxed out at 32psi, but meh.

At 32 psi it made 1200HP at 7000rpm.

Finally an update!

Right-o, there's actually been some progress, and it'll snowball from here-on.

I've cut a big hole in the firewall that allows the motor to sit 165mm further back in the car. The tunnel has also been cut out to just past the shifter hole. (the poor old girl is really starting to look like swiss cheese) I'll do the motor set-up and then put a removable tunnel/fiewall box in it as the last thing. I also fabbed up some solid engine mounts to keep the sucker still.

We had a look at position of the turbo last night, but I won't finalise that till the turbo collector arrives from Kyle at 6BOOST Manifolds (www.6BOOST.com) and will depend on collector length and turn radii etc. Originally I had visions of it fitting under the hood - but I must have been on some wicked acid the day I hatched that one. There is absolutely no way it will fit under the hood - although I don't really care. I'll be making a fibreglass hood anyway in an attempt to drop some weight. Note the fact we had to use an engine crane to position the turbo:rotflol:.

Proof that big turbos attract pussy :D

[perthdrivers.txt]

Jeezus that turbo is comically large :D

I think the car itself looks fantastic too

top work!

[out_in_front]

might want to keep the cat away when you get around to starting it - that thing looks perfect for small animal ingestion.

With the firewall cut I am guessing this thing will be off the street now??
