Everyone seems to only be comparing K24/18gs to K16/24s. I thought the K16/16g was the best setup for K16 hybrids? How does the K16/16g compare?

Which is the better choice if keeping stock fuel with a 5 Bar FPR? It seems the K24/18g wouldn't be used to it's potential w/o larger injectors. Injectors seem like such a PITA to do. Plus I have to limit myself somewhere.

Also, this hasn't been discussed here, but how does an electronic boost controller play a role with this? Quicker boost response? Would I want one on a 5BAR FPR fuel setup with K16/16g or K24/18g setup?

Disagreed here, for the power level that K24 moded has the curve should have been shifter even more.. I was accused of comparing apples to oranges when using two modded turbos to show how they compare and the difference in low end power and torque was substantial and in favor of the K16. Unfortunatelly the K16 dyno sheet has disappeared from my post, which is quite interesting and I hope I did not step on that persons toes when I posted their dyno sheet....But fret not theres more to come, take a look below and see how a K16 hybrid does...

I like how the K16/hybrid dyno sheet has disappeared from my post. That dyno compared to the K24/18G said a lot and it showed how two modded turbos work which is much more apples to apples than the dyno above.

So here is a modded K16 UMW hybrid turbo with full race file from UMW and I apologize to Kevin at UMW if he did not want me pilfering his data.


compare that to JohnD's K24/18G on race fuel


look at the difference in power and how soon it comes on. A lowly K16 hybrid versus the K24 hybrid BOTH on race GAS.

at 3100 rpm the K16 hybrid was yanking 480+ ft-lbs of torque, the K24 hybrid was at 325. The K16 was producing 328 at 2000 rpm....

Look,
if doesnt matter what you post... it still is a different car with a different set up... any tuner can crank up the timing to make a turbo spool up faster... ( not saying anyone did)...
my point is that someone else will come and show you a K(whatever) turbo beat down a K16 or whatever else...
the only way to really compare is to have one tuner do all the testing with all other things being equal... thats the only way you can really tell about the characterisitics one of turbo to another.
Thats like having one driver run 2 different cars at the same track vs. two different drivers in respective cars... One is always going to be a faster driver...

That was kinda my point a few pages back when John posted. It seems most people who HAD K16's feel they are now FASTER with K24's, dyno sheets aside. John did say that he thought the K16 was quicker light to light, but he has proven beyond a reasonable doubt IN HIS CAR that the K24 hybrids are faster at the track and likely on the street. Not really sure what the OP's question really was, but if he takes a ride in a K16 hybrid car and a K24 hybrid car, he will have his answer, for the most part.

 

so your saying that the K24 hybrid above is still faster than the K16 hybrid in the curve I posted above?? So a turbo producing less torque throughout it's entire range, less power as well and not having as broad a curve is going to be faster? I think we can all safely say that is not the case here. The K16 hybrid above absolutely demolishes the K24 hybrid numbers and that is an undeniable fact. I just wanted to show that when your talking hybrids, the rule that you run out of juice on the high end with a K16 is a fallacy and it is proven above.

 

No I'm not saying that. You quoted my post, but I don't think you read it. A dyno sheet means nothing, and by that I mean what Markski said a few pages ago...ALL THINGS BEING EQUAL.
This thread is about lag not how much power which turbo makes. The OP had it right in his first post. Also, are you trying to say that these "magic" K16's are making 640whp with 1.25 bar as John's 18G's, if not, this is yet again another useless "arguement".

 

If you are trying to argue that a hybrid K16/24 with a race file will outperform a set of K24/18G turbos with fuel, intake, race fuel, etc. (as my car is configured for the dyno above), you are wrong. If you ever drove one with race fuel and high boost, you would understand why. KPG had a UMW K16/24 tune with race file and he tried numerous 1/4 mile runs, even went back with drag radials and could barely crack 11.6 with a 122 trap in the 1/4 mile and ran a 128MPH trap tops with a slower ET. Kevin is not a newcomer to 1/4 mile runs either, so he is not a novice driver. We were both trying to get down to 11.2 - 11.4 on hybrid K16/24's and neither of us could do it with numerous tries on more than one day. The first pass I made with my K24/18G's was 11.2 at 132, second 11.1, third 11.0 all with traps well into the 130's.

Is that a 2wd dyno? or maybe an optimistic dyno? or something other than K16/24's? The EPL numbers are Mustang AWHP.

 

I'll take that action. What are the terms of the bet?

 

Bandimere raceway in Denver. Come on over, bring your car with stock injectors/pump (like mine) and we race on pump gas, to show reality on the street....Bottle of Johnny Walker Blue to the winner.

 

Hopefully someone in Colorado with 24/18s can meet you there. I'd love to see this happen.

 

I can't remember...was KPG running a full Stage 3 on race gas when he posted those numbers?

 

No sir. John claimed it was a race gas file,but that is not correct. Stg2 ZC turbos, miltek exhaust, stock FPR,ported stock headers, pump gas file with Sunoco 94 with 4 gals of 100 thrown in, full weight AWD. That is all....

 

I just checked KPG's dyno from the car that posted the quarter mile times/speeds you posted, and it showed peak torque of 565 and peak horsepower of 510 on race gas (AWD dyno). The Stage 3 K16/Hybrid dyno posted above shows about 600 lb-ft of torque and 640 hp (I assume it was on an AWD dyno).

 

That's what I thought...looked it up while you were posting the clarification.

 

Dock, that dyno above is a RWD dyno.
