LSA SLC Build Log

Bob, I am also using a intercooler for my oil temp control. It came from a Ford cop car. I like yours. Can you provide sources for components. It looks like you made your own container. Any thoughts on selection of internal oil cooler size, water flow rate or restriction of same, other relevant information.
 
C&R Racing has different sizes of heat exchangers (1-317-293-4100). They were helpful sizing the cooler to my application. They also sell complete units. I had a unique situation since my cooling tubes were finished, I had to make the cooler tank fit my car ... kinda backwards ... The core was $250 .. So I saved a little cash making my own tank, and it fits the space I had for it so all worked out !
 
Fran,

How is this mounted to the chassis? Is it bonded or bolted to the Chassis. i assume that the upper section is bonded to the roof. But I'm just curious about the tub. It really looks like a great piece for the SLC.

I know it looked awesome in the LeMans version that you had in Charlotte.

With the upper and lower pulley, ported snout, and LS9 injectors, Lingenfelter said 625-650HP should be within reach.
depending on the tune that's very achievable. My daily driver is a 2012 CTS-V wagon, and I spend time over at CTSVowners.com where plenty of people making 600+ at the wheels with similar mods (so ~700 at the crank) - again based on the tune.

I'm about 500 HP at the wheels with an auto (so ~600 at the crank estimated) with fewer mods, and it's blindingly fast. I can't imagine a car half the weight of my vagon with even more power. Insane, in a good way :thumbsup:

Questions:

1 - Are you going to try any of the 3rd party adjustable traction control systems? What size rear tires are you going with?

2 - Are you going to use a larger reservoir for the air-to-water intercooler - or just rely on the additional fluid in the system (i assume you're piping that to a HX up front, in addition to the radiator)

3 - What mufflers did you pick?

Anyways, great build.

Id like to see the tub, the exhaust looks killer.
Hope you can still hear the blower
The blower sound in an LSA is heard from the intake side, not the exhaust side.

on the CTSV and ZL1 it's very noticeable if you ditch the stock airbox and go with one of many cold air intakes (CAI). get on the throttle and the demon whine of the roots style supercharger is something to behold.
 
I was thinking about traction control, but I'm not sure if it will make it in the budget. May just try it without it the first season out. I am using the stock Z06 size tires front and rear.

Heat exchangers: I called around and tried to make sure I was going to have enough cooling capacity for the HP I hope to make. I ended up having two dual pass coolers made that will mount in the scoops in front of the rear tires. I also made a tank + pump assembly that will hold close to 1 gallon of coolant. Tank has a temp sender, so I will be able to monitor system temp.

Mufflers are Dynatech Split flow, with power cones installed in the 3"
I don't want it too loud, want to hear the supercharger !

That sound is going to be right next to my ear in my layout! Hope I have have enough room to pack in sufficient insulation around the intake (roof scoop) tract.
 
So my nephew turned 16 years old ... So Uncle Bob (me) is gonna fix up something for his first car ... One thing leads to another as you all know.
What started off as just some small issues with a nice used truck, turned in to a partial respray, LOTS of small things, and an interior cleaning that ended up gutting the cab.

I highly doubt it Bob.

Maybe you could remove the stock GM motor mounts from the engine whilst supporting the drivetrain and slide the engine mount crossmember for or aft and get enough clearance to remove the oil pan?
 
Warning to all. It is near impossible
to remove an oil pan from an LS.
Or at least it was for me with my
combination.
End result was to cut out the cross
member, remove it in three sections,
and fab a new one that will come out
If needed.
Parts are at powder coater, I'll post pix
once it's all back in.

The GM mounts that Fran supplied. With the windage and pickup tube on this LSA .... The pan had to come STRAIGHT down. I felt I was too far along to considder removing the engine, just to get the pan off. The way that the cross member is now held in the "pockets" on the ends, I think it should be as strong as the original design, but will allow removal. Hope Fran approves ? LOL
