Then do it! Let’s see what ya can do. Even a big turbo will loose some power/efficiency as boost builds. There’s no such thing as free horsepower.. I was considering going turbo, a 98mm, but running a turbo is a little more complicated than I’m ready to try. Not that a procharger isn’t complicated, but it is easier than a turbo.... Not waisting time with a belt drive, they tend to fly off, crank driven to me is the drag racers friend.
That does look cool, but man does that stick way the heck out there. I can see space being an issue in some vehicles that way. I don't think either way blower or turbo is not complicated. I have no real first hand experience with either. But I can see that turbos might fit into smaller spaces engine bays better.
Well if you want to add some ballast to the front end, the ProCharger is the way to go! Hopefully you have enough RPM to get as much boost as you want. Either look cool to me. No One races turbochargers at low RPM that's why they're always in some type of form of boost at launch. But I'll guarantee you this at max RPM the efficiency of a turbocharger is higher than a supercharger. You cannot mistake a top end charge from a turbo. It's interesting watching the nitrous and ProCharger guys in the no prep series switching over to turbos.
Well no prep is somewhat different too......without a good launch surface the instant on power of the nitrous cars can be tough to manage......even with all the progressive timers I don't think it's a easy to manage the power with it as it is with the boost. Again I have no experience with any of this, but a lot of those big no prep cars are not your 50k racecar either........those are 200k+ machines that the average Joe just can't play with...........motorsports is pay to play, and in some fields them with the biggest wallets wins
In my opinion a Procharger is a gear driven turbocharger. It will give you a very similar top end pull, and middle, and launch as compared to a roots supercharger power at the hit and fade down track.
What is your impression that makes the turbo more complicated than a procharger? Some more "plumbing", but this can be packaged under the hood pretty easily. I think you should definitely revisit the turbo route. Once the thing is plumbed you get to do tuning and make sure it has plenty of fuel delivered. Boost is just a measure of how efficient the inlet system and ports in the heads are. By increasing the flow, the heat is increased but there are many ways to counter act that. This gets us back to the need for a standalone to run the fuel and spark to use the turbo "easy button". This guy does some pretty nifty diy fab in his garage,
My son & his friend don't have 10K in the car & best to date is an 8.01 a couple weeks ago. They are doing well enough that company's are looking to them for testing their products. We'll see how well that goes & wish them luck on Hot Rods Drag Week. Tom T.
Maybe several of the people “replying” Do not drag race.... Do you guys think I didn’t do any research?? Here’re what I learned; between the turbo and the procharger you’ll basically spend the same amount of cash, and get close to the same horsepower results. The cost of a good big turbo is equal to the cost of the procharger, the turbos gonna need custom hot & cold sides built, equal in cost to the procharger crank drive., Ignition, fuel and some other vital components between the 2 are the same.. The Procharger is more similar to the nitrous combination I’ve been racing for a very long time, in regards to the launch and racing., “People” have talked about the “no prep” racing, have ya seen a turbo car stage and launch??? Bump box and other crap, is what I think make it harder than dealing with the procharger, like John E said “it’s basically a crank driven turbo”... I thought a turbo was free horsepower, but after actually talking to Precision Turbo, I learned a ton..... Boost is measured by inlet/motor efficiency, But, as boost builds, it definitely puts more load/stress on the motor reducing efficiency, still makes big power, but there’s always something.....It’s all so simple talking about it, but learning about it, and actually making it happen in the expensive real world, that’s a whole other ball game.....This is an open forum, so Opinions will be shared, but let’s all be realistic....

Guys, Having just built the lastest EFI/DIS/Pro-charged 555, I chuckle a little bit at anyone who thinks there is anything "simple" going on here.. And if your even worried about expense.. stop now, and buy a boat, learn to play golf.. whatever... I'd venture that there is more money sitting on that engine stand in my shop, than most bracket racers have in a nice 10 second GS back-half car.. the whole car, engine an all.. JW
I’m not sure about the intake, I’ll need to do some more research, I’m guessing there’s Big block Mopars out there with Procharger’s, and the intake is a Mopar Super Victor,, But reality is it probably will Not work and I’ll have to figuout something else ($$$).,, That’d be “typical”.,,,, Gary G
8.01 in the 1320 has to be somewhere near 165mph. To not have 10k in a motor, trans, suspension, brakes, safety equipment, cage, etc.........seems unlikely. Even in a car that is 2500 lbs you would still be needing 950-1000hp to do that times.........and motors to make that level of power and live are well over 10k. Something doesnt sound right here. I know I would drive an 8.0 car if they told me they built the entire thing motor and all for under 10k with mostly new parts....I would get afraid to die in that thing
Gary .. Anything packing loaded more air into the cylinder is going to add tresss anything internally.. that's a given. as for your intake situation wanted to just run a Max wedge intake and run one of those elbow to the throttle body then connect it to the pro charger? However, that would put you in the multi-port
Someone mentioned running 8.0s, my guess it’s NOT a Buick...... I run the Super Victor intake, not the max wedge one......
Just talked with my son, Billy, & his friend Dave who owns the car. I was slightly off in my figures AFTER talking with them. They have closer to 15K in the WHOLE car. The car was somewhat a race car already that the previous owner thought was used up so Dave picked it up REAL CHEAP!!! It ONLY has a glass hood & deck-lid. The rest of the car is steel. . Dave & my son did what was nec. to find & fix the short comings to make it a drive-able race car. My son spec'd out & built the WHOLE suspension himself only buying what was needed to come up with the combo they were looking for. So far everything they have done is mostly built by my son & Dave. Dave says the car is so stable he can almost drive it with one finger. So far I have not seen it get out of shape. Maybe they have just been lucky. The way it is now the way my son set it up the front weighs 100pds. more than the rear. They could just change tires & rally the car. This vehicle is registered & insured & is docile enough to drive from Daves house to my sons house about 35 miles away & WITHOUT over heating. That's an 8.01ET @ 172MPH with a 1.11 60 foot in a 3200pd. car with driver. This weekend they pulled out the 8.8 & put in another rear & it's stronger & lighter & saved 30+pds. It's in an '85 Fox Body car. It was a used 6.2 with 500 miles on it that had a crack in the block. It was in a newer GMC pick-up 2500 4wd. GM decided to just put in another COMPLETE new engine & not take a chance on a repair. Dave picked it up for core value of $400.00. Dave asked my son to look at the crack & said/decided he could repair it. The ONLY thing they changed was the cam AFTER my son did his homework & spec'd it out. Took out the pistons. Opened the end gaps on the rings & honed the cylinders for more clearance. EVERYTHING IS STOCK AS IT CAME FROM THE FACTORY. This past winter they removed the engine & took it apart & put it back together again with NO NEW PARTS except for gaskets & other small things. It has been running now for more than 3yrs. & adding more POWER through tuning. Tuning plays a HUGE part in things lasting. After EVERY run out comes the laptop. It's mostly about the DATA collected & how it gets applied. As for HP they were close to 1K at the wheels when it was 1st.put together. The way we tuned back in the day was just an educated guess. There's NO WAY you can advance or retard the timing by 1/2* or 1* with a timing light. Most EVERYTHING we did back in the day was just a guess hoping we did the right things in the correct order. Today it's ALL ABOUT DATA. I'm VERY PROUD of my son Billy & ALSO his brother Tommy for the inventive ways they can & do solve problems & for the most part do ALL their own building of nec. parts. Not all of course as some things need to be bought. AGAIN, wishing them the best of luck for drag week!!!! Tom T.
