well I kinda went off the deep end and picked up a CTSV last week...

In the stupid scheme of things, if I do something silly like upgrade the headunit to either the LS9 or a 2300 tvs etc. on the caddy....how hard would it be to get that LSA unit working on my suburban? Has L92 heads on it already...

 

First off... UPDATE YOUR DAMN SIG!

Second- congrats on the awesome new ride

There will be pulley issues and you'll have to relocate the air intake tube, but if you are patient I think you can work it out. It will definitely be worth it and you won't be wasting the blower. However, it may be more practical to sell the blower to somebody who can more easily use it (maybe with a G8 or something) and buy a TVS or other FI system that is designed to work with the truck's accessories. Just my $.02.

 

like he said... as far as getting it on, just swapping to the car accessories and re routing the intake... other than that will eb the obvious fuel system changes etc. I think it could be pulled off and be a really badass upgrade

 

 

sounds like too much work I think I'll just take the 1500 dollar core charge....

 

Do you really need or want to upgrade the supercharger on the CTSV?

We all know how articles go, but in the latest edition of GM High-Tech, there is a 2009 with a built bottom-end (stock crank, Callies rods, JE pistons) 9.0:1 compression, ported LSA heads, 237/248 .586/.586 113 LSA hydraulic roller, stock 1.7 rockers, stock GM 90mm throttle-body, 100lb injectors, 14.8 psi of boost, D3 Super Intercooler – air to water, Kooks 1.7/8” long tubes and puts down 670rwhp/600ft-lbs. With N2O, it puts down 865rwhp/848ft-lbs and runs 9.85 @ 139mph, with a 1.49 60ft. Of course it has suspension and driveline modifications, but pretty minor all things considered and still runs the stock GM IRS with 3.73 gears and posi. Transmission is a 6L90E with stock torque converter.

Pretty stout for an all-to-small TVS-1900!

 

Do I need it? no, but you see my stable, I'm probably the only person who buys a 556 horsepower car and doesn't think its all that fast....

realistically we all know pushing a 1900 that hard for more than 10 seconds at a time is gonna cause massive heatsoak issues, the bigger headunits have much better internal cooling besides going bigger externally. The tvs on the truck would be nicer for towing as well, 10k trailers and hills suck ***** with a gasser, I SO wish GM would put a goddamn turbo diesel in a SUV....and for 6500 I could have both vehicles happier, but swapping everything to car accessories and having to reroute crap...I'm not digging it. The paxton made power but just ran too hot towing.

 

I dont buy into the so called " heat soak" issues your talking about.

My IAT's after a run are damn near identicle to my friends similiar equipped truck with a 2300 on it, in fact they are within a dergree or two of each other.
