It would be cool to build two identical engines, put them on dynos side by side, and have one spin a supercharger while the other one feeds off the supercharger output. See how much it actually takes to drive the 'charger.
It depends on a lot of things, engine size, blower size, pulley configuration, gear ratio etc. Some engines use 2000 hp to turn the blower, some use 15. Turbo is a restriction in the exhaust system to start with so just bolting a turbo on doesn't mean it isn't using any power. Bolt a turbo on a engine with the gate open and see if it makes the same power, I'd put my paycheck it wont.
I've been running a turbo on a DSS Pro Bullet with 331 stroker kit ( stock block, just dressed up @DSS) for 8 years and 30k miles. It can be done , but you must know that you have good air/fuel( gotta have a good wide band, such as Innovate) and don't get too greedy. You must be sure your tune is good. i have been running 10psi on the HP kit, making 511 rwhp and 622 ft. lbls. rear wheel torque. Any questions ,feel free to pm.
The extra exhaust piping alone would reduce the power output of a turbo motor vs. a similar n/a motor. In your example the compressor would serve as a restriction in the intake tract. So, of course there would be a loss of power. However, the compressor is not a restriction when it's actually making power, and while added exhaust pressure is the cause of the parasitic loss associated with a turbo, there is also clearly a great deal of thermal and kinetic energy in the exhaust of a motor that goes to waste. This is obviously nothing new to you, bentley. To clarify, I think everyone here recognizes that parasitic loss still exists with a turbo.
Here's a more relevant bet: at a given positive boost pressure on a given motor, given a builder's choice of supercharger vs. another builder's choice of turbocharger, the turbocharger will always make more power/have less parasitic loss.
If that statement is false, despite the fact that it's a very broad generalization that uses the word "always" as part of a condition, I'd be surprised.
Yep I agree with all that 100%. I just hate seeing how everyone says a turbo doesnt use any power and blowers use a ton. Its just not true and so many have been brainwashed like that.
It depends on so much. A F1R on a given engine at 20 psi is going to make more power then say a 72mm at 20 psi because the blower is moving a lot more air. Now say we are compaing to a gt4788, same engine same 20 psi the turbo is going to make more power. There are tons of variables, its hard to compare apples to apples in my eyes they are different animals.
Blowers win races, turbos set records.
i have an ON3PERFORMANCE kit installed on my 306. i can only run 10lbs or less because i am right at 10:1 and have a domed piston. the sharp angles on the dome is weak point for heat. unless running meth injection kit which is recommended. i have good internals and aluminum heads made 438 on engine dyno. since turbo installation on 6lbs the car is retarded. downshift from 5th to 4th at 65 on the highway and hold on! car walks WAAAY out ! havent had it on a dyno yet but soon. the kit installation is fairly simple...tight in some places especially on lx nose. other than plug wires ive had no issues. deffinetly wrap the down pipe. spend the 100.00 to wrap the turbo itself ....and sleeve the plug wires. doesnt take long to cook a set with the extra heat. ive heard the 500hp limit on stock block , and i agree that the stock block is only going to handle so much. but...we ran the same 70mm turbo on stock everything at 15lbs for over a year before it lost oil pressure . oil pump drive shaft looked like a twizzler! beat the crap out of that old motor alot! roll of the dice i guess when you are dealing with the kind of internal pressure created by turbo. the guys at ON3 are straight forward and if it wont work on your set up he will tell you.
The other thing I think people misunderstand is that boost pressure is largely affected by engine size and efficiency, and manifold pressure (boost) isn't always a direct indicator of what pressures the combustion chamber is seeing. Just because dude "A" got away with running 15 psi on his stock headed 302, that doesn't mean dude "B" is "safe" with 15 psi on his H/C/I 302.
Good point to bring up, I would not spin a stock 5.0 past 5800 rpms, I'm more comfortable with like 5400, I think that is a real killer of these motors.
just keep in mind that just because one person got lucky and was able to make XXX amount of power on XXX amount of boost, nitrous, or whatever . DOES NOT mean that it will work on your set up. many variables to consider when talking power adders of any kind, that being said. no matter what you do or how much you spend.....something is going to give at some point! i build my engines to be run hard and do exactly that....run them hard. i have a 100% success rate on finding the weak link eventually. sometimes you get lucky......sometimes ...not so much.
Pm has been sent! Hey guys bringing this thread back to life! After have sooo much fun building my SRT and GSX, I've learned the turbo life lol, I see everyone's points. I see my old post and I laugh now, with that said I'm currently building a 06 evo 9 and bout to be done with that project, my stang has been in storage for a lil over a year. One thing I've learned from my previous turbo builds is that I LOVE TURBO!!!! lol. So I'm going to turbo my stang, but I'm going to do it the right way! First step is to get rid of that block and getting one that will handle my stroke kit plus my turbo desire. This build will take some time..... well a long time, I want to measure 2-4 TIMES and cut one! I'll start my build post around summer hopefully so you guys can see the progress.
