Lag vs. HP for Various Turbos

Joe, I have a similar story to John. My guess is the reason Porsche does not use them is they cost more money...the process to machine them is more precise and requires more processing time (it's not materials). This of course is a no no in the mass production of cars. Also ECU programming may need to be tuned better...again this takes time. I had the "stage 2" with stock K16s and GIAC flash. The car was fast and ran well. I have had my 16/24 hybrids and my 2nd custom program and I must say less lag then any of my previous set-ups and very fast. I'm planning on dyno runs in the next couple of weeks. I'm not sure what you m ean by free lunch BTW...the hybrid turbos cost $$$ too.

The ultimate "no lag" powerful turbo is Kevins stage 5 zero clearance with billet WGs. hard to explain unless u had them... I did.. as well as 2 other set ups...

After some research, I decided K16/24 hybrids best suited my goals. There were several options...standard K16/24, low clearance K16/24 (.003 vs. .008 stock), zero clearance K16/24 (require strict break-in or they are ruined) and K16/24 low or zero clearance with 1.2 bar wastegates (either heavier spring version of the originals or custom billet wastegates). I choose the K16/24 hybrids with .003 low clearance (supposedly an exact replica of the RUF turbo - low clearance is a major ingredient of how RUF gets their power) combined with the custom billet 1.2 bar wastegates. .

Everybody has there own opinions but the programing is just as important as what turbo's you have.It is often said on this board that K24's are laggy yet our 550 which has 24/26 has the same lag as a car with stock K16's.I am not saying on tuner is better than another or which Hybrid is best.

ebaker,
Yes, they are the GT-1 turbo. Speed gallery's K16/24 hybrid turbos go like this:
K16/24 turbo (GT1) - standard hybrid
K16/24 low tolerance hybrid turbo - same as above, but good for additional 20HP and quicker spool
K16/24 low tolerance hybrid turbo/billet wastegate = same as above with billet wastegate to hold the boost better and enhance turbo response
According to SG the package is good for about 550HP before the ported headers, Evo V-Flo, silicon hoses, etc. - so somewhere between 500-600 HP depending on the car. The headers dyno around 18HP and the V-Flo at this level is supposedly in the 20's. The FVD Stage 2 was quoted as 510HP and I had the V-Flo on top of that. I drove the car before and after the silicon hoses and the hoses seem to increase the flow and enhance the turbos response, as well.
In real world driving, if I had to describe the difference between the two levels, I would say the difference is like going from stock to stage 2 one more time - in other words, double the increase of a stage 2...maybe a little more. The acceleration is much more violent in nature and becomes very apparent on tight back roads where the car feels "significantly faster" in close quarters. On the highway, the car pulls very strong and at WOT passes much quicker than with stage 2.
Bottom line - I am not sure what the HP is, but it is a noticable step up from stage 2 and feels like it's probably nearing the limit of the stock internals.
