Intercooler mounted! In total I need to move the radiator back 1.5”. That’s not bad, from the stock location I think that is more around 2.0”. You can see the saw cuts in the radiator support to French in the Intercooler to the radiator support. Again the intercooler measures 24x12x4” core dimensions, bar and plate style. Overall tank to tank is 28” and spigot to spigot is 31”. A person could easily do a 27” wide core, there is more than enough room. The intercooler is sized to support 900HP, my goal is 800HP. Should be adequate upto 1000HP with a properly size turbocharger.

If anyone attempts this, a 3” core would be a lot easier.

Was going to get the radiator mount done tonight as well but I managed to shear the shaft off on the angle grinder. Not sure if I should go corded or cordless.

Well I will get more pictures tomorrow up once I finish weld this out, but here’s a teaser of a mandrel 4” exhaust system over the axle and out the back. 5” down pipe made it to the bottom of the firewall in total is just over 50” long. Also made a custom eccentric reducer, it is just over 8” long for a nice transition. Should be enough to support 1000+ hp my research tells me.

Had 2 hours tonight to finish up the wastegate. Little complicated with a turn up and then to plain out, but overall it worked out good. With the angle of re-entry back into the main pipe I am hoping it will create some scavenging up stream. It would reduce backpressure and help with spool times.

Time to finish weld out a bunch of stuff now. Should be a wrap for anything exhaust related!

So I got major red light here. I failed at hood clearance. With the adapter and stack up I am short 1.25” for the hood to fit, and that’s with a 4” cowl hood.

So I drafted up a adapter plate to machine out of a piece of 1” thick 6061-T6 aluminum. The adapter will be 0.75” thick. I will be using a spread bore bolt pattern and dominator bolt pattern. 4150 will not work this way. The 4500 bolts will be frenched into the spacer and the spread bore bolts will be threaded for studs.

All said in done I should be approx 0.5” under a 4” cowl hood. Should find out in a week I am thinking.

Got a green light of hood clearance again. buddy made me a 4500-4150 adapter that is 0.75” thick. Leaves me 0.5” under a 4” cowel hood. That’s more than enough clearance now.

I got the water cooling lines installed for the wastegate.

And last was the oil manifold distribution block. Fabricated this one out of a 1.25”x7” piece of 6061 aluminum. Put a lot of mounting holes in just because bit over it turned out well. Oil pressure sensor, oil light switch, and water pump switch will be coming off the block as well the turbo oil feed line.

Got the new power steering pump and bracket in place. Bracket is something I made, probably over kill heavy duty but it will work. Basically a slider plate style bracket, worked good. V-Belt is really short and full half wrap contact. hopefully this power steering pump will work with a hydro boost, it is rated for 1200psi @ 3.5gpm.

Alternator mount and adjuster done! Little high for my liking but it will do. The oil manifold block is right below it. If anything it is up out of the way of any major heat sources

Got the regulator and return line mounted. This is nice and close and should provide a good reference to the regulator. Need to order a couple 1/16npt fittings to hard line the reference line to the sniper.

Well one side of the charge tube is completed. 3.5” from the intercooler to the carb hat. Dual 50mm BOV. Figure it’s a good idea given the hammer/surge one could get blasting through gears. Keep in mind I have a synchronized transmission so I must lift. Still need to hard line the manifold reference signal.

Next problem is a driver side battery I was planning. The standard battery is too wide. I ran out of room unless I am going to cut up the fender... he’ll if that’s going to happen.

Well it’s not pretty but it works. Battery tray on driver side complete. I decided to use 2 of my side x side batteries. They have the correct height to just slip in the fender. Should be around 550 CCA. Not ideal but nor is the location. If needs be there is enough space to fit 3 of these batteries in there but we’ll try 2 first.

Vacuum pump mount completed. It is quit low but definitely out of the way and should stay cool while being used on the street. Might collect some bug guts down there but meh.

Also got the power steering cooler mounted. If bet the years I can honestly say if your running a hydro boost and a quick ratio steering box, a cooler should be used. The fluid can reach 260f on a hot day and usually that is close to oil break down. I mounted mine in the inner fender wheel well with the driver side tire. This is a high pressure zone and should provide a lot of f cooling capacity. Might see some damage from street driving, I am not to concerned for the amount I drive the car.
