Adding some more giddy up (Boost) to the GTO

Well for a long time I have warned to hang a Procharger setup on the GTO. That time has come. Used Procharger kits for the GTO don`t come on the market very often so when I found this one I jumped at it. It`s not fully complete but has most of the important stuff. It`s one of there D1SC headunits. Planning on getting the kit hopefully installed this summer on 8lbs. Then adding meth injection and turning it up to 12lb. Should be in the 600whp range. Looking forward to it since I have always been a nitrous guy.



 
I`ve always had a thing for the 05-06 GTO`s. It`s such a sleeper to most people (besides the hood scoops) but with an exhaust it sounds amazing with the LS2 under the hood.
 
Looks like a nice find on a used peice. Take some advice for a guy who has modded plenty of cars in my day. Make sure you have the budget to fix what breaks before you start and realize you will be giving up reliability in the same percentage as the money`s you spend in relation to the car cost.

I heavily modded a supra turbo fully hks. Once it was done I swear I pushed that puppy as many miles as I drove it. Engine just could not handle the power. And the supra was new as was the HKS kit!

Next was a 1988 M3 great car for 40k stock miles. Warranty over boom Dinnan chip euro injectors and lights and a whole bunch of junk. Same problems. Pushed more than driven. I loved that car. Had it towed in and returned to bone stock. Drove it to 165k and 7 trouble free years after return to stock.

I have not modded much since. Now I just buy hem how I want them and it far cheaper and you get a warranty.

Just my 2 cents before you strap that baby on your gto.

I think a lot of it also depends on the platform. For the LSx engines I wouldn`t worry too much about the engine with forced induction. Now the rear ends are another story, at least in the f-bodies, not sure what GM used in the GTO`s. But I believe anyone who does want to start modding understands the potential risk associated with it and you have to take the good with the bad. It`s an addicting hobby that people enjoy and gives someone a sense of accomplishment. And most people that modify a car to the extent of more than just simple bolt ons have other means of transportation, so if the car is down for a few days it`s not a huge deal, just annoying.

Fully understand what is involved in a built car. Had a 10 sec Camaro that I sprayed for 9yrs before spinning a bearing. I did however have to replace everything behind it lol.

The GTO isn`t really going to see the track pretty much for your reasons listed above. The clutch is all set, rearend has gforce axles and I have replaced most of the bushings with polyurethane. Just looking for more of a fun Street car to blast around in.
 
Do you have any plans for tire upgrades? If I remember right, you can`t really stuff wide tires in the back of GTO`s without doing a mini-tub, something like 265`s max stock?

Someone with experience understands the economic concept of "diminishing returns". While I am not an engineer, I would find out how much to torque (NOT horsepower) your rear end can withstand or what it`s designed for. A safe bet is 10-15% above STOCK (as in new from the factory) engine output ratings and go from there. Chances are that you will burn off your tires before breaking an axle or pinion gear from a starting launch, but if high speed (top end) is your goal, then bearings and brakes become an issue. Also GTO body design is NOT an aerodynamic wonder, so again, if top speed is your goal, someone`s remark about "that thing is going to fly" can be quite literal!! There is a reason why aerodynamic engineers add spoilers , underbody tunnels, or change body line contours to cars like the Camaro Z28 from computer simulations to wind tunnel testing to actual track test runs.

You are correct. I could swap to a 15x10 drag wheel with a 275/50/15 but again this isn`t going to be a drag car. Currently I have 19s on it. I will probably slap a 19in drag radial on it and call it a day.

Like you said I will most likely blow through tires. This car is not a purpose built drag/top speed or road race car. But with a drag tire on a prepped track the rear would be on borrowed time.

Will do!
 
Very cool! You will love it! Similar history to mine: was hitting my Nova with the juice and then decided to build an F1R sbc for it! LOVED that Procharger!

Keep us posted!
 
Getting a tray fitted to manage the air under the car, and a rear valence to channel that air would be something I`d ;look into. If you need a reference, go into a Porsche dealer and look under the Turbo, its flat with channels and can am style scoops to allow for brake cooling and air management. The rear tail and front air dam are for more than looks. you don`t want your front end unplanted when powering through a turn, or your rear coming unglued as you exist and apex and stomp the gazzz.

Have fun, and be safe. Car engineers are pretty dern smart and if you add to much under the hood, the rest will suffer fast.

Oh man these D1SC sound so cool (like a space ship)! I almost picked one up two weeks ago but the S/N was defaced...

Congrats! You`ll be smoking lots of cars and some exotics that`s for sure.
