Cutler or Twisted

The twisted kit has a new fuel rail for dual injectors. It also has an aftermarket fuel pressure regulator to handle the higher volume fuel pump. Freak, you are right in that the oil pump could still malfunction and you could loose a turbo (which is worse, motor or turbo)?

As I said before, all good kits. The TT kit worked better for me.

CC - Your right , "just a matter of time". Sad we cannot discuss differences in kits without bashing and who did this and who said that :(

I was enjoying learning from the discussion, to bad someone had to step in a **** it up.
 
Ummm not quite but almost... the volume of the charge tube is proportional to the square of the radius of the tube, so if you double the tube radius, you can 1/4 the length of the tube to get the same volume.

ummmm, what?

Im talking about ID and you are talking about radius?....radius is half of the ID

read my post a little slower this time...no worries sunshine:face-icon-small-hap
 
I have been reading this for quite some time and keeping my mouth shut. Have to chime in now. First, the shortest most efficient (easy radius turns, smooth welds, excellent airbox, and all connections and hoses to be top quality including a clamp assembly on the pipe to Y pipe connection) charge tube and turbo dump help to eliminate lag and inefficient means of getting fuel into the burn chamber. It is common sense along with simple physics. :face-icon-small-ton This also applies to BOV and any other components as well like boost controls etc.

Yes, a larger degree bend in any pipe will slow flow (just a bit)...but it’s hard to imagine this would be a big deal on thses lawnmower engines. I work on equipment that sees 2000PSI in a 48" pipe and over flows over 1 billion cubic feet of gas a day. From what I see and test, a 90 degree elbow will only decrease pressure/flow/temp by .5%…. so this cant really be a big deal on these lawnmower engines.
 
I would be careful of side mounted charge tubes it was proven to cause problems back when Brad Story designed the kit that twisted is running. Brad quit using the oil injection pump to oil the turbo for a reason and the side mounted air box for a reason you may want to talk with Brad and he can explain what the problems will be in the long run because he is the one that tested these items.

And what would this reason be Mr. Wizard?

a pump is a pump, if the turbo is getting enough flow and pressure….well, its should be fine

I would trust the oil injection pump and add an RTD/TC in the turbo drain line…maybe

hatch after that day at tower I understand how you might refer to yours as a "lawnmower engine" LMAO

that was the past, got some stuff fixed and soon to be in optimal condition after shain gets his hands on her:cool:

and the lawnmover ref: is cuz i work on stuff that makes over 30K HP:light:

and you know my sled will lay the smack down on your white wounded duck when your off the bottle, my new track will set the bar for all those who challenge the great Sir Hatchers :).....i must say, your sled felt a bit slow when i rode it.....must be your wimpy track and picnic basket you have mounted on the back, lol

I did all of the research on turbo kits.

Push - looks good but not proven
Boondocker - it works
Cutler - makes quality stuff
Twisted - Will get you high HP
OVS - gives you both

Call Gar or Travis and go ride.

:D
:eek:
:D
 
Seems to me that Twisted Nation has alot more positive feedback on here than any other kit. If you want to see a good movie, go where the line is the longest!
 
If I was looking at buying a turbo kit I would not buy one from somebody that has nothing better to do than to get on here and bash someone elses product.

That is pretty low class....
 
ti must say, your sled felt a bit slow when i rode it.....must be your wimpy track and picnic basket you have mounted on the back, lol

that's cause I hit the valet switch right before I let you on it hahaha .... don't forget about the pink handlebar tassels "they're the coolest, everyone's doin it" right CC?
 
back to thread topic I rode a cpc m 1000 turbo yesterday and I have to say it worked very well nice job dale although I do perfer the twisted set up.
 
Let me us talk about this charge tube….the charge tube volume in-between the exit of the turbo charger and intake of the engine is the only thing that needs to be reviewed. So a ½” tube that is 2 foot long will take the same amount of time to equalize X amount of PSI as a 1” tube that is 1 foot long.

Q: why not make a 1” tube twice the distance, and run some of this 1” tube somewhere it can get some cooling…….hummm I got an idea:cool:

ummmm, what?

Im talking about ID and you are talking about radius?....radius is half of the ID

Umm again not quite Hatchers, but no worries, sunshine. Since you think it's only important to review the volume of the charge tube, I would think you'd want it reviewed correctly.

The volume of the tube is;

Pi * r squared * length

Or, if you wish to speak in ID, is Pi * (1/2 * ID) squared * length

So you're originally talking about a 1/2" ID 2 foot long charge tube.

You ask why not make it 1" ID 1 foot long.

The reason you don't is because by doing do you effectively go from a volume of 0.0625"" * 3.1415 * 24"= 4.71225 cubic inches (that's your 1/2" ID two foot long charge tube) to a volume of

0.25"" * 3.1415 * 12" = 9.4245 cubic inches. (that's your 1" ID 1 foot long tube volume)

You want me to re-read you message again? OK I will but every time I do you just end up wrong again, sunshine. :)

You want to know why those #'s work out that way?

It's because the volume is still proportional to the square of the radius of the tube. It's not a linear relationship. Or as you prefer, the square of 1/2 the ID. Same thing.

Maybe you'll want to re-read my post, this time a little bit slower.

I like the idea of the cold air intake vs. under hood intake.

Freak - do you know if anyone has run temp probes for intake air temps and for charge air temps in an underhood vs. cold air intake scenario to see the actual differential?

I wonder if the turbo compression process adds so much heat to the charge air that the delta in temp from underhood and outside becomes insignificant in the big picture or not?
 
What kind of horsepower is being made by the pump kits on the M1000??? Is the horsepower of the Twisted vs. Cutler about the same??? Do they both run about the same PSI safely on pump gas???

holly crap im feel dumb, thanks for schooling me in basic math:o.......for some reason i was thinking a tube is square....and yes, proportional gains in pipe ID is not linear..:beer;

once again, my bad:face-icon-small-ton

Dude I dont run anything but a boost gauge, real men dont need fancy gadgetry, they smell the exhaust, lick the plugs and catch the vibe from the motor :)

altho would b cool 2 see intake vs charge temps. I got that on my SRT8 maybe I can borrow it for a ride ;)

Turbos love cold air, period.
