Intresting point you have there im not sure if we could push that blower 4.6 mustangs use kb 1.7l kits
the benefit to the turbo is running the high boost, heat really is not the problem it is how fast the blower can spin before it will seize.

yeah you can run the 2.8 with 60lbs and with all the cooling mods and a full exhaust and lets not forget the intake with a 50 shot of nitrous and be completely safe everyday for the rest of the cars life as long as your sprayin into tha blower....am i not correct ? but i allready know there are some ppl that will not use Nitrous... to get that magical 300 hp
2.8 and 42's with stock timing and a 75 shot. I have sprays about 5-6 bottles and the blades look fine still.

For comparison, my buddy has an SRT-4 that has about 280whp and 330wtrq, if not more, on a stock turbo with all sorts of toys. My car and his car are on pace with each other give or take a bumper when we run. I am only running 15* of timing as well, and I have not yet tuned for the meth, but I do spray it for the cooling properties.
Alright, here is my performance mod list:
2.6" ZZP Pulley, HPTuners PRO tuned by me, 60lb flow matched injectors, Devil's Own Methanol kit w/ boost pressure switch (50/50 mix), Cometic 2.2L headgasket (lowered compression around .2-.5), Golden Eagle headstuds, Injen intake, CTI header w/ 3" catless downpipe, Corsa Touring catback, DIY Dual-Pass mod, Exedy Hypersingle clutch/flywheel, Driveshaft Shop Stage 2 axles, Ingalls TD, light 17x7.5" Rota Subzeros wrapped in 235/45/17 Toyo T1R's (shaved 10lbs on each corner compared to stock setup), B&M "x-tra" short shifter, and an AEM UEGO to monitor it all
This is what the twinscrew will have for supporting mods going onto my car a lot sooner than everyone here knows. Obviously the 2.6" pulley is coming off, but you guys get the idea. The bottom end and cylinder head are all stock as well. I think that with what I have already, inconjunction with the twinscrew I'll make my 350whp goal.
Now, the dyno I go to is a Mustang Dyno that rates on the low side. I laid down 197whp and 177wtrq with just the Injen intake at 90+ degress and humid out in Charleston. I bet that I lay down around 330-340whp on this dyno when all is said and done which will definitely be higher on a Dynojet or other dyno. This is just my logic however from looking at the original dyno posted.

You won't lay down that much power on a mustang dyno sorry it won't happen. The 281whp was on a dynojet if i recall. You might get 300 when all is said and done, you will only have exhaust and meth on the car supporting mods don't do much for the car, there kit runs a 4pass endplate for cooling. The lighter wheels will help out the dyno though.

ok let me take a crack at this
1. You are assuming that since it says 15000rpm max on the compressor map that is the max for even instantaneous. It's hard to believe that 14000rpm is max for continous and another 1k is for instant. But regardless I will discuss this matter in detail with the engineers at lysholm.
2. I have driven both the turbo cobalt and Twin Screw each for 1-2 weeks and I must say they were very close in power. On top of this the turbo cobalt had a full 3" exhaust with no cat. I even drove the turbo cobalt at the track with slicks and it was a pain to get boost off the line, with the twin screw it just there all the time. Even when you are just driving on the road it so smooth when push from low rpms.
We encourage threads like this as we want to develop products that keep our customers 100% satisfied even if it means making the damn blowers ourselves with forged rotors and quality bearings.
We will know more this week as two of the kits should be installed on vehicles with proper mods.

This is what ive been saying in the 1242342134 million other threads ive started about us needing forged rotors and bigger bearings that can take more load. Here is a comparison of the KB 2.2L/2.4L TS compared top the lysholm 2.3L TS. Look how much bigger the bearings are and how much more the KB can withstand because of it. If you want to spin to 20+K forged rotors and bearings will be a must. End of story. You will be the greatest thing since sliced bread if you do this lol.

Let's take a look at the dyno Rebel did already with a little projection I laid over it. I hope we can all at least agree they weren't tuned all the way yet, and that the blower will make power all the way to redline by looking at the graph in comparison to everyone else dynos on here.
Now here is what I came up with. Looking at this as a fair projection of how the dyno would have ended the car would have clearly made at least 300whp. Take my mods and add some timing and I think 350whp is very do-able.

I, for one, would like to know how you have had access to these cars, without saying who you are. Are you the guy who tuned them? I bet there are many who want to know who rebel really is, before shelling out cash. Honesty and dislosure will probably net you some gross.

Man no offense but this projected graph is nothing but an error ... You'll never see 350whp coming out from the stock head, unless it will be a very unefficient setup, like a HUGE turbo or a serious shot of nitrous. Exhaust ports and cam lift dimension are the bottleneck.
Also, a Mustang dyno is usually 9-10% lower than a Dynojet, so please forget definitly about 350whp on a Mustang Dyno. Think about 275-300whp on a Mustang dyno with all bolt-ons, thus with a very good setup.

He had acces to them b/c he was had made both of these car . 2 he does do the tuning for these cars . rebel is 2 guys doing work on are cars . i have know these guys for long time now, and i complete trust these guys , there are not here to screw u guys , they just want theses cars to go fast and be safe .
yea car makes power to 7 grand with TS
