Twinscrew Current Dyno Numbers & Issues
Awesome job so far, I can see good things in the future for this setup!
One thing you mentioned worries me though. I don't think de-sensitizing the knock sensor is a good idea. That sensor is there to protect your car and it is very sensitive for a reason. By messing with it, your eliminating the false knock, but your also preventing it from detecting actual knock as well. Just be careful when you playing with things like that.

No hijacking the thread or anything or trying to make negative comments toward the twinscrew or anything for that matter but i thought when purchase the twinscrew and put it on you are suppose to be around 350whp with a tune so is it me or just the dyno that is messin with my thoughts
The reason 2K5SS/SC? has to tweak his tune is because he's nothing close to stock before slapping on the kit.
Great job so far
it's always a battle with the things you never think of.

It all depends on how your car is set up before the install. Meth also from what I hear is a pain to deal with. Even with pulleys and injectors on our eaton you see people dyno up to 20whp less with the same mods. As bad as things sounded it should easily be hitting 300+ with a good set up of both car and tune. Plus, it isn't 3000 really it is +2200 since you are upgrading from an 800 model. Frankly, the efficiency is worth the money even if no power is gained. Just my point of view. Still can't afford one though. (3000k = 3,000,000)

i dont think you've proved anything but 281 whp at 5700 rpms...everything else is just what you think..and it will continue to just be what you think till the numbers show other wise...i'm not bashing i wanna go twinscrew i just want to wait till its right

Well 250whp on a Mustang Dyno is impressive. Whats the highest dyno in your shop with the M62 Cobalt or Redline??? ANd what were the mods. That will make people more belivable of the power then just 1 number.

Thanks for the positive posts gents. I promise that this is not the last of twinscrew, and all of it's potential will shine soon enough. That 272WHP was just the bottom of the barrel with the methanol when it's added to the mix. There was a ton of timing and A/F tuning to go all over the place as timing was at only 17-19* and the A/F was around 10.9 - 11.1 across the board on that run. It was also about 90*+ inside the bay where the car was dyno'd. The coolant went up to 210* at one point, so we had to let her cool down awhile. Just some minor set backs, but a least my engine didn't blow from the meth mix being dumped in there! that's what I'm really happy with right now more than anything!
As a side note just to **** the rest of my day off the guy at the Sonic dumped a Route 44 Ocean Water and a Large coke on the side of my car when I went to grab some grub an hour ago!
I just washed the damn car today too! 
I guess if it weren't for bad luck, I'd have no luck at all!

thats not too bad.....270ish on a mustang dyno you made 199whp with an intake on this same dyno? with an intake, you should probally make 215+ on a dynojet, so i would say on that one pull, you damn near 300whp.....with some more tuning and fixing you meth issues....I think you should see your +300whp in no time....
There is also a smaller pulley too, right?? I am assuming that once you get a the bugs worked out, you might be goin that way down the road???
anyways best of luck and hope you get it alll worked out!

Is it true that allthough the twinscrew reduces heat and increases power, is it allready running beyond its efficiency range in RPM? This is what i heard im looking for data to say other wise. Could someone tell me what the crank on the 2.0 is so i can do the math and find out if it is in or out of it range?

People need to stop guessing Dnumbers and get this thing done correctly. 272 is a good number on a mustang dyno. But its not a good number for the amount of money spent. 3k for the kit plus full exhaust and intake + Tune + Clutch. People have to realize to run this kit at full power you will have to spend atleast 5,000 dollars and thats if you install and tune the stuff yourself.

Only way I am seeing 300+ being able to come from this kit guaranteed is with cams and headwork. Even with all that, I don't think you will even be able to get 320+ though. Meth will only help so much, it doesn't do for us like it does for Turbo guys.
Good luck none the less, can't wait to see it doing better. Can we get a dyno chart?
PS: Don't know why in the other threads you were saying it pulled so freaking hard when you were only putting down 226 TQ, that is fairly close to stock. Go find a 2.5 pullied eaton, I am curious

On the same Mustang dyno I laid down 197WHP with the injen intake. With Stage 2 and an exhaust added I remember making around 212WHP. With my 2.6" pulley, header, and all the other crap on the car without the dual pass or methanol injection I made 238WHP and 230WTRQ. Rolling off the dyno with and unfinished tune without methanol and laying down 260WHP and 226WHP is still an improvement over my last run. The car runs so much better on the street now it's not funny. The powerband is a lot smoother and the car tends not to be so jerky now.
Take a look at the dyno graph from yesterday. The higher run is just before the meth blow out incident. The one below it is a decent tune that was done in a short amount of time, and the one I left the dyno with. The torque curve shows that between 2473 and 4400 that we can still add timing to bump up those numbers and smooth out that section to broaden the torque curve. Yes, even know the car was heatsoaked, it still made power up to redline whereas my eaton was peaking at around 6500rpms and certainly would have not allowed the timing we are running with the car at the moment without methanol.

Excuses, Excuses, Excuses. This post just proves that the kit is not a direct bolt-in. So on top of the 3K dollar asking price you'll need to spend 300-400 dollars to have it tuned. 
Even more if you need someone to install it for you. What a waste

Wow it took you longer than I expected to respond. I thought you'd have 15 posts in this thread by now.
