I need to know if I can run a turbo,charger with 14.1 compression.I don't want to change anything on motor just want to upgrade to a pro charger bolt on
 
i doubt anyone here is going to attempt to answer this so ill try.......first...welcome!

what kind of engine is this?
you say pro charger, but then are talkin about a turbo so did u mean supercharged?
how do you know you have 14-1?
EFI or Carb?
what kind of PSI are you planing to run?
what kind of fuel system do you have?
(We need more specs)

its practically impossible to just bolt a turbo or supercharger on and not change anything else. i'd say if this engine isent built to the gills with the best of the best you wont be wanting to run boost either, and even if it was, it wouldn't last long probably.


i'd also be willing to say if you couldn't answer this yourself, you shoulden't even attempt it. it takes alot of research, experience, and cash to go turbo/super on an engine like that. better option would be to spray it. cheap and not the hardest thing in the world to learn about.
 
Yes - with a diesel. Gas engine? Probably not.

I kind of agree with Nitrouspete, are you sure that you have 14:1 compression now? That type of compression needs some really powerful fuel to ignite. Even your best race gas can only support 13:1 - 14:1 compression. I would think that if you have 14:1 compression you are probably running some pretty substantial fuel even without a power-adder. To go higher that 14:1 (through mechanical compression or forced-induction) you would need to consider alcohol or nitromethane. Nitromethane might allow you to run what you are proposing; a turbo or Procharger, especially when you consider that nitromethane can cool the intake charge better than gasoline. But, an engine that can hold up to that isn't going to come cheap and it isn't going to be you find in ANY factory-built car. That would have to be a purpose-built race engine.

There are lots of very helpful and knowledgeable people on this board. And probably some on here who could actually help build and engine that could hold up to the kind of power that you are asking about. But, your question is kind of vague. Bottom line is that we really need some more information on exactly what you have and how it is set up.
 
Even if you spray that motor with NOS it probably won't last long. Usually dome pistons don't like spray all that much...or at least that has been my experience.
 
Fuck yeah. Do it. Make sure you get the first pass on video. You should be fine with pump gas.

OK the motor is built ,I run under nine in a quarter with a 250 shot.I was thinking of go in a diiferent route 'I see all these out there with turbos and creating hp and spraying .just WS wondering the specs.I run 116 octane.SBC 434,950 demon

You need to do some research, no a high compression motor will not like boost. At a minimum you will likely be changing out pistons to drop compression to run boost. 9:1 is a good target, lower if you go big on boost.

Agreed. Drop the compression and run big boost. Change your fuel to accommodate. Consider Nitro. If you are running in the 8's now you are probably about maxed out on the set up you have. You need to consider more cubes, more compression, & different fuel. Think top fuel funny car...

All turbos and superchargers do is increase the pressure in your cylinders. At 14:1 compression you already have that. Another thing to consider is that 116 Octane fuel will not support more compression through mechanical means or forced induction. There really isn't a quick-change solution for you to get more power. The faster you want to go the more difficult it is to get there.

If you are really looking to run faster you need to take your car to a speed shop. You need a system-based solution to get your car to run faster. Putting a turbo on or running a Procharger and not changing anything else will only overboost you engine and blow the heads off.

In short optimus, No you can not just bolt on any power adder and go.

if i were you, it sounds like you got a nice set up, why not slap on 1 or 2 1050 carbs? and insted of a single 250 shot, slap on some foggers and tune the nitrous to come on in stages?

change a rear end gear?
 
maybe your tuning was off on the 1050...big engine should like more air and fuel, not less.

fogger will wake it up...just be sure to change ur plugs, and adjust your timing.
 
Yep I always change the plugs after every grudge but the carb was tuned in by my motor guy which is very good but I just want that 8 n and passes and I'm bout there it just seems like I stuck on what to do to get it ,trust me I've did a lot to this a lot time and money invested but that dam half second is fucking with me.trying to figure what else to do to get it .the motor loves the juice but don't want to push it either .I had a 406 in it and feed it to much spray and and I split the crank in half ,half way thru the season,it was a eagle crank at that. I was pushing 700 without spray with that one and would only get a really high nine out of it.so now I got the 434 and I'm flat nine which is good but when u can get that mid eight or low eight I'll be satisfied
