RUNAMUCK

You had me at redwood tavern.

Did you connect power to your anti diesling soleniod?

As above. My 1564cc datsun makes 10-11psi with a large cam. I ran my indentical set up on another A series motor (1397cc's) with a stock cam and made around one bar of boost. That very same motor (In another life) made around 11psi with a big (N/A) cam. If you're going to all the trouble of forcing, then fitting a nice big cam is a no brainer. Blower grinds run a wider LSA. This reduces the overlap, reducing charge going out the tail pipe. And opens the ex valve sooner. (sooner before BDC) This bleeds off a little bit of power, but uses some of the energy of the still expanding gas to evacuate the cylinder. Since the in side is being forced in, it helps the motor expel the used gas. Some forced cams run a bit of extra duration on the exhuast too. I know one bloke who has run a few 350's on nitrous. He reckoned sometimes he'd fit higher ratio rocker arms on the exhaust valves to help with those duties. You asking for your boat Sentra? The other two upsides to running a larger cam is, lower boost figure means denser charger. And bigger intake vent means more charge gets in, and more power is made. win-win. (Although your sweet W2A intercooler must really get the density up)

PS, Feel free to check my maths above. I aint no rocket scientist. And it's quite possible I fucked it up.

225cubes per rev is the bit we need to know. All things being equal if one was run on a 225 slant six at 1:1, it would make one bar. I had heard somewhere that they didn't displace the full 426 cubes per rev. So 265cui X16.39= 4343cc X5500=23888425 /2=11944212.5cc of air. 7psi+14.7psi/14.7psi=1.476 (Boost ratio) 11944212.5 X 1.476=17631932.74 (CC's of air required to create 7psi boost) Blower displacement: 225 X 16.39=3687.75CC's per rev. 17631932.74(CC's of air to make 7psi)/3687.75 (CC's per rev of the blower) =4781.21 (Blower rpms) 4781.21/5500= .8693126940:1 Blower drive ratio required to make 7psi on a 265 cubic inch motor. Now In my experience, that actual ration wouldnt quite make 7psi. It might come close if the blower was freshly overhauled, and clearance'd nice and tight. Heat isn't as much of a factor in losing boost. It just tends to reduce the density of the charge. (And therefore reduce power) I did once read some where on the www that if a roots blower is turned slowly, there is more time for the air to leak past the rotors. And it was better to spin a small blower fast, than to spin a big blower slowly. (Just the opinion of that person btw, not what I myself think) Also blower speed isn't always the greatest contributer to heat generation. (Although obviously if you put an S/C12 on a 440 big block it would damn near catch fire if spun fast enough to make boost) Depending on how well designed a given blower is, it's the actual compression of the air which heats it up. Some blowers heat the air more than others. I would personally not bother trying to get more than 12psi from a roots blower. Although on the right kind of setup (Intercooler etc) more might be do-able

This is only around 16 paydays aways. We may have to convene a meeting of interested parties at some point in the future, and ascertain who genuinely is down for it. And which vehicles will be going/up to the trip.

I wuz gonna show my face, but a wakeboarding sojourn ran into overtime when the boat motor coughed it's lot. It created a few challenges that although not insurmountable, did take longer than I originally anticipated.

Dont take the whole 426cu thing as gospel. It's not quite that. (Don't ask me what it actually displaces) My old man is planning to fit a 4/71 to a 265 hemi down the track. So your numbers are quite relevent to his build. I run an S/C14 (Allegedly 1.4 litre) on a 1500cc motor. @ 1:1 ratio. Makes 10-11psi. Here is a post I found on another site about working out boost

Would trade again.

GAL! God damn it, you're a worry son. It breaks my heart to hear you've disimproved the body on your twelvie. The only thing for it is to paint strip the whole car, and roll rat spec.

Both is best. I had my clutch bonded and rivited. Rivits only hold in one spot. Bonding has a greater surface area.

The Redwood Hotel is a Hotel, they won't like BYO. Fear not lingling. Our meets don't garner huge crowds. I reckon a jug or two and a handfull of 7oz glasses will make the grade. So when is this thing?

Dude where's your car? I was thinking about a question you posed ages ago. When you made the wise decision to go forced induction, you comented that the good folk at Kelfords advised you that the cams they sold you wouldn't be ideal for boost. (And you should buy new ones for $123456789. I was thinking about this a while ago. If you have adjustable cam gears, you can alter your LCA to suit boost. So do a skid.

On my rotang I used a set of factory leads of a piston engined pop up headlight mazda cosmo. They were as good as the cool cables. But nothing else has ever come close.

Maybe try a sheet of stainless, with a layer of cermaic type wool. I think it's called kao wool? (We used to say it Kay-oh wool) I think it came from forman insulation. I also used to use it inside ovens back when I built those.

I think thats what resistor type spark plugs are supposed to do.

Those leads from canterbury auto electical are pretty good. I beleive they're called "cool cables". But they're only available in 7mm now I think. They have the lowest resistance of any leads I've ever seen.

That would be correct. This car is fucking awsome on 100 different levels.

I've never used it, but the seppo's swear by the shit.

Could be a rotten frost plug.

It's a pity they don't sell normal beer there.

Thursday was a most enjoyably evening. Great to meet you sheepers. The Celica is such an epic car. Many thanks for the ride. Good to catch up with Richie again, and to see the other usual suspects.

Allright, Booking is made for 7pm this thursday. Harringtons cafe and bar 808 main north road. I booked the table under the name "oldschool" since I dunno who would get their 1st. See you there!

7 sounds good to me too.

What time do y'all wanna eat?
