We placed a big order with Jeg's tonight for the Ranger:
10pt roll bar kit Aeromotive 1000 pump Aeromotive 2000 bypass boost ref regulator 5pt Simpson harness 8AN billet aluminum dual feed inlet line Aermotive fitting kit for the regulator
Gotta spend some dough if I want to get this thing running by May....LOL...I'm picking up the rear shock kit tommorow at the post office and I also got a mint 750DP carb as well for the blow thru setup. Intercooled or not we will be making boost in 07.

I got the rear shocks installed today, there were no installation instructions with the kit so I had to wing it ....Didn't go too bad, I'll have to take the axle to work so I can use the stick welder to finish welding the lower shock brackets on the axle. They are so close to the 4 link brackets on one side I can't get my MIG in there....Stick is the trick....LOL.... My installed spring height is 16.5", the recommended is 15-1/4 to 15-3/4 so once I get the 10pt roll bar kit, battery, fuel cell and my fat arse stuffed in there I should be bang on ;D....The springs are quite soft, we guessed at a spring weight because they were included with the kit. I may have to buy another set once I get my truck weighed.....I have to thread my diagonal link tommorow and other than a little more welding the rear suspension is done. Yesterday we installed new front brakes - rotors, bearings, pads, hoses and etc. I plumbed/flared the front hard lines and installed/plumbed the line lock. Still waiting on the big Jeg's order so we can keep on installing/fabbing stuff.

The rear springs are tricky with the trucks, I am finding that out. I ordered 200lb springs based on the total weigth of my truck, but because the back end is so light, it seems too stiff, almost like i could have used 150's or 180's. Gonna wait and see what it hooks/leaves like before i go changing them though.

2 schools of thought on spring rates, for years the thought was to use the smallest spring rate that would hold a car(truck) at ride height. Has worked for us, Albert and I use 110 Lb springs, Dave MacKinnon uses 90's(of course the pigblock up front may affect it ;D ;D ;D). The idea was to have lost of stored energy in the spring to help hit the tires initially. Now people are going to heavier springs but only 150 or 175 to help the shocks control squat which single adjustable shocks do not adjust as well. But this is more common on higher HP cars where the hit from the engine is more than enough to make the tire work. Lower HP cars I think should still use a very low rate spring.

I went with 130lb springs, with the turbo's I won't get that big, hard hit on the rear tires like you would with a big block or nitrous engine leaving against a transbrake....The boost is progressive and a little bit linear. The springs seem to be quite soft, with the shocks set to the "1" or the softest setting it seems a little too soft. Having said that with the shocks set on "12" I can stand in the box and it acts like the truck is solid mounted to the axle.....LOL...It will take some tweaking to find the sweet spot I guess. I'm still far ahead of the stock leaf spring setup with all this adjustability. I'll get the truck weighed and dyno'd in the spring. I'll have to frig with the bar angles and such for this year while using my used 15-9-26 slicks, I built the 4 link for a 30" tall slick. I had a look at it and I'm sure I can get my bar angles close enough for the 26" slick to work until I have the money next winter to cut the diff and buy new 14x30 slicks/wheels that it was built for. I'm not too impressed with Jegs, our order still hasn't been shipped. ...They are holding up progress on the next big job - the 10pt roll bar.

The problem i am having is that the spring is not compressing enough (not enough weight on it) to suit the way the chassis is built. My coil over brackets are in the lowest position to acheive ride height, but that makes the brackets themselves to close to the ground by about 1.5". Hoping that the weight of the baterties will make the difference but i don't think. Looking like 150lb springs may be a must, as i I agree completly with the soft spring/high rebound theory.

I'm only about 3/4" from the recommended install height and I think when I add the battery, fuel cell, roll bar, driver and etc I'll be right in the ballpark. To run the 26" used slicks I'll have to raise my shocks on the rear end and raise my lower bar up one hole on the axle, it will get my bar angles right....Not ideal but workable for now. The way things are going now I'm gonna be hard pressed to make opening weekend in Greenfield....Jeg's is screwing me around on my rollbar kit and it looks like the middle of next month before I might get it....We told them to ship the rest of the stuff now so we can complete the fuel system.
I'm getting so materials today to build a sump for my fuel cell and some piping to start plumbing the turbo's.

Just a FYI Chipper and Stuart, when I refer to a low HP car I include mine in that picture. Dave and Albert are getting to the higher HP level but even Albert is just 3 clicks from full soft on his Strange adjustables. The Powell's T-Bird is what I mean by big HP. For you guys 110 or lower spring rates.

Dont see much x bracing in the frame at all. I would be adding lots as it will make a huge difference on how your chassis performs. Have to say too, your welds look awesome.

I made sure I put the pretty welds in the picture, the rest aren't so pretty....LOL ;D....I'll try the 130's and see what happens....I'm going to brace things once we get the roll bar installed - it will be x-braced on the rear struts.
