Yes, I have been reading a lot about racers using nitrous to spool large turbos and then shut off the nitrous after the boost gets over a certain amount. The inter-cooling effects of the nitrous alone are incredible, not to mention the extra power!!!! This seems like a great use of nitrous since it cools the charge, helps the turbos get up to full boost and then shuts off which makes the bottle last a long time. http://www.nitrous.info/nitrous-with-turbos.htm
The Devils Own Kit guy told me that you can get as much as a 200* drop in temperature. This has to be at least a 75% efficiency. Then you have the fact that the alcohol/water raises the octane of the fuel. This is why you can run huge boost numbers on pump gas.
Careful James, some guys on the board get pissed at "I was told" stuff, even though being told information is the basis of our entire education system.
Not much done today. Over the weekend i went to a city auction and picked up 2 lighting cabinets from an arena for $1 a piece. I just finished stripping out 1 and got $103 from the copper and aluminum in it. I have about the same in the second cabinet and almost have that one stripped for tomorrow. Hoping to make $200 from them. Not bad for a $2 investment. Only cost me about 10 hours and a 12 pack.:error: This money is going towards the carb. I found a 750 DP with annular boosters and 4 corner idle on eBay. I'll chop off the choke tower and add the E85 metering blocks and have a pretty good carb. I've learned to go cheap in the right areas and go all out in the others. The carb is one area to do it right the first time.
switching to a higher gear(3.08/3.23) will also make the turbo spool up faster but of course might hinder some of youre lowend...but if you build boost at the stagging lane/launch i doubt it'd matter much
Don't worry. I haven't forgot about the 350 turbo build up. Just have been helping out with the pole barn and working on the truck. I'll give a good update tonight. I'm deeper than i wanted to get on the body of the truck. Oh well.:beer Jeramie
So i haven't really done much to the engine but am getting deep into the body of the truck. The bed was shot. We've been glassing and bondoing it for the last 8 years. Took the seats and roll bar out so i could get the bedliner out to mount the fuel tank, battery, and trans cooler. The floor was worse than i thought. Took a hammer and hit it and chunks of the floor were falling out. So cut the bed of and am in search of another. Then the front fenders and hood are no different. For $200 i can have new fenders and hood. Worth it in my opinion. Then I'm also reworking the suspension a little. Lowered the front about 3 inches buy re-indexing the torsion bars and in the rear removed 1.5 leaves from the spring pack and added 2" blocks. Then I've also had the front hubs redrilled from the Mazda 6 lug to the Ford 5 lug to match the rear. Surprisingly all the suspension components are tight and in good shape. Did i ever mention the body has over 300,000 miles on it. Now for the engine. I haven't really done much since i got it back from the machine shop. I tried fitting the cam but it doesn't fit so that will be a different thread. Thinking this weekend or next week i'll get the short block put together. That's about all I have for now. I'll see if i can find some pics to post up. Jeramie
Still haven't forgot about this project. Being unemployed put the brakes on the whole project but that is hopefully soon to change. Changing to a different cam that's going to be bigger but is on a 114 lobe sep so that should be good. Also trying to convince myself that i should really open up the ports in the heads and see how fast we can go. I'm also excited that the NHRA changed their cage rules for trucks eliminating the bars that go into the bed. Got most of the body work done on the truck. Just needs new fenders, hood, passengers door, bed. The cab was rust free though. Been doing quite abit of powder coating on the truck. Did the calipers, caliper brackets, rear drums, valve covers, hood hinges. Next up is the TA intake, carb body and bowls. Did everything in gloss black, doing the intake in a high gloss red which is actually pretty close to Buick red and not sure on what color for the carb. I'm sure i'll do the turbo to and might even try the heads if I'm feeling really crazy. This project is still moving, just really slow. Just need the cam, heads milled for the rocker conversion and the rockers then were in business. I'll be sure to post up when something happens. Jeramie
Thanks for the update! I would not worry too much about the heads since you are adding boost... I would look at getting the exhaust to flow well though.
I've been looking at it and I'm going to run 2 drivers side manifolds. So i'd run the pipe from the driverside manifold back under the engine like if it had a single exhaust then forward under the motor mount. Then the passenger side will dump into that pipe then get increased to 3" at that point till the turbo. The exhaust will hopefully be 4" if i can fit it, otherwise it'll be 3.5". I'll for sure put a cut out in it and a straight through type of muffler. I've been playing with those online et calculators and i need 600 hp to break into the high 9's. So i'd like to be in the 350 hp range before the turbo if possible. If not i suppose there's always nitrous. :Brow: I've got a bunch of various stones and files left from a set of 500 Cadillac heads i ported 2 years ago. I think I'll give it a whirl. I've read and reread the head porting article so i think i have a good idea where to remove some material. We'll see what happens. Jeramie
