well it doesnt make much sense when you say heat kills the pistons but then you turn around and state how running richer than rich best torque saves the engine. Below rich best tq significantly increases egts. Which will melt **** down. The best policy is the sweet spot between the 2 with timing to match.

If you wanna go dyno racing there are ways to fudge the numbers.We DO NOT!
I've Personally dyno'd over 40 cobalts on the dyno and 100's of other cars that weren't cobalts. I've seen that same car go to another dyno and make 15-20% more or less.


We would have finished the tuning on the twin screw ourselves, but do not have a car with a clutch in it to take the power it is making. The stock clutch is not up to the power this kit is making thus we sent out the first kit to 2K5SS/SC?
The Kit is a direct bolt on you Unbolt and re-bolt. The tune is still being developed, you have to understand that the twin screw is nothing like the M62 interms of tuning.
We ask that everyone be patient with us and 2K5SS/SC?. He is busting his ass to get things tuned up right.

You have the exedy right? I have the exedy AND a solid top motor mount (metal on metal) +intense trans mounts and I have 0 false knock readings. Your clutch is definately not a factor of false knock and I seriously doubt the blower is.

You shouldnt need meth until over 23psi. I ran 21 psi and 19 deg of timing on my turbo on pump gas and made 305 whp on a mustang style dyno with a shitty tune (huge afr fluxuations due to blow thru maf sensor...lost 25whp in the mid range due to that spike)



Quit making guesstimates...This car is the "dream situation car" for you guys as it has every mod u said should make astounding power...and so far its not up to what you said it should







The stock head is fine to 450whp. The cams are the true problem...they are TINY,



Tune it to 11.5-12.0 for more power. See what I said above about timing and boost on pump gas.



In the above post i mentioned that their factors of possible knock are not the reasons. To show it is you need to get the vibration frequencies of the blower and get the spec of the sensor to show they really are. In this case decreasing the knock sensitivity would just risk the motor.



From what I can see on his chart hes right around 230whp at that rpm using a generous correction factor 15% for dynojet correction he is only at 265whp. Im not seeing this huge increase in power



This compressor isnt that efficient. Here it is overlaid with the map of a turbo of my car (in green) graph is adjusted so axis values can overlay exactly:





See above post to Rebel. At this point your up 34hp over a stock car...not that impressive



Honestly this car should be cake to tune since it is using a draw thru maf in the same piping he was using before. run a SD tune for a couple runs to eliminate chance of p0068 code then maf tune for all of the 30 minutes it takes tops and its good to go. Turbo cars are considerably harder especially in blow thru apps. Stock style metering systems are cake.



EXACTLY



I would prefer a company finishes their own tuning and development then to pass it onto a customer. I dont know why your even selling the kit when the tune isnt even done yet. BTW ZZP claims over 270whp on a 2.8 M62 car tho I am semi skeptical due to lack of mods listed. Tho it is a mustang dyno. They just started the thread a few days ago. Tho only track numbers will tell the truth. Its easy to make dyno lie.



Just talked about above. IMO this is unimmpresive so far.

Im tired of seeing speculation and for that reason have given my responses to the above posts. Enjoy

I never said running richer than rich saves the engine, i was givin 2 choices and I chose runnin rich instead of blowin 200 degrees IAT2's. As I stated above I know that running too rich is not good. You can tune all u want, but when the SC/turbo is blowing nothing but hot air, a few mouse clicks aint savin the engine.

I agree that you want a good balance but heat MUST be managed in that scenario. That was the only thing I was trying to say since the begining

heres their mustang dyno showing 270, before the final tune on both cars... and its a mustang dyno. everyone seems to think 10% over that is realistic for a dynojet, doing the math would be 297 whp my friends.







i dont personally discredit you and your knowledge, however, stop coming into any thread that is a dan turbo'd his redline ZOMG thread and talk down. Yes you built your own turbo set up, congrats, how much did you get paid doing it? what shop do you own? exactly, your experties are lacking at best. We're all happy you made 305 whp with your over sized turbo on a **** tune on a mustang dyno. how long did it take you to set it up, and it wasnt even tuned properly then, so why are u knocking his unperfected car. His car once tuned fully will in reality make the same numbers your car is making. Sure maybe it wont have the huge possibility your diesel truck turbo'd car may have but lets be honest, who cares. There seems to however be ALOT of issues, and i wish he would both use a dynojet, and have someone who knows alot about hpt finish the tuning, or perhaps not post until its done and said #'s are seen. no point being little bitchy honda drivers and fighting over #'s
