When comparing blowers, cant forget you have to take into consideration of each mod each truck has...

 

Well both the Roush and the Magna are 1.8L M112 Roots blowers, but the stage 4 port that troyer has done makes a BIG difference not so much in just peak power, but it keeps the blower at lower temps to maintain a power that a roots normally has problems with.

 

Not just the port job but the more boost roush guys run. By the way magnacharger makes the roush unit.

my magna is a MP112

 

We all can spin our tires from idle so that is no big deal. What you do after that is what counts.
As far as your magnacharger bashing..........bring it on because it's really getting old.

Looking at your performance mods, post, and when you installed them, $10k spent would be a low ball park estimate on how you got your 13.6 time.
That leaves me just over $6300 to pick up 3/10ths of a second to run faster than your 13.6 in a truck not built for speed.

 

Well its the exact same blower. 1 PSI isnt a huge world of difference. 1PSI really makes between 10-20HP at the flywheel. Which with these trucks would probably be 5-8RWHP

I dont believe any F150 was ever built for speed other then the Lightning.

 

drew what gear ratio do you have

 

don't they run 10 psi? and a port would only increase the flow so much more causing a loss in boost showing 8 psi?

More Air= More power?

 

Do you have a updated track time other then the 14.0?

 

As I understand it from troyer he changes out the S/C pulley with a light weight pulley with the port kit. I believe it makes about 8.5PSI or so. A port will bring down the boost shown on a gauge, I dunno by how much.

 

Like I have been telling you, here in California making power is harder for us than these guy who put our trucks down..

Example of a California built engine with low numbers.

 

I thought the roush kit was 8 psi stock... humm...

 

I would have to agree with this...

 

That truck has some seriously low boost for that set up, and shorty headers dont help at all.

 

It is 8PSI stock if you get the inner cooled one. However troyer changes out the pulley(s) for light weight ones if you get the upgrade kit from him.

 

that's what im saying stock 8psi, 2lb upgrade = 10 lbs total then port makes it 8lbs again but flows so much more air now

so in theory more power right?
