awsome numbers just by porting the stock blower:rockon:
thanks true forged for the kick ass port!!:beer:

385hp to 422hp
492tq to 515tq
i was really happy about the torque because u usually lose when u port the blower but i actually gained:banana:

Nice improvement and good to see some numbers from a True Forged port:beer:.

Here's the thread. I lowered my upgrade price in like post #7. We've both been saying this is the cheapest way to get a great performing port for the least amount of money that it will ever get done for.:beer:

^That's for Cobra's only.


edit: I just saw his thread over here and that is NUTS!!!!!!!!!!!!!!!!!!!!!!!!!!! You guys need to jump on this while it's going on. Wow.

Crazy is what this is.

No props to the tuner :p

A/f is 11.5 until it pegs the maf and runs up top 12.2. He's been warned to stay out of it until he comes back with a MAFIA. I have been impressed with the TruForged blowers. I think it will make even more power once he ditches that Volant intake.

6lb lower
2lb upper
c&l plenum
sb throttle body
cai
borla exhaust
and the air fuel ratio im going by the graph and the line was around 12

only 13lbs?

I made 13.xx on stock upper/blower with 6 lower. I added a ported blower and a 2.7 upper and see 16.4lbs

13 seems quite low with that pulley combo

13lbs? Whats with that, pulley combo like that should yield higher

Either ditch the Volant, take off the outer case, or cut some holes in it. Thats why your only seeing 13#'s of boost Those things are restrictive if not modified.

Take off the CAI and make a pull and see if u get more boost. Talk with others of a 'True Forged port' and see if this is normal. Sometimes porting your blower will reduce boost but give u more airflow.

Think of Boost pressure sorta like an water hose. If u cover the end of the hose with your thumb pressure increases(this is sort of like a un-ported blower), take your thumb off and pressure decreases but it will flow more water with less pressure(this is like porting your blower). More airflow, less pressure (boost).

That is some nice gains for a good price on the blower Port. If I wasn't selling the truck, I would be all over that for the price.

I dont subscribe to that theory. Let me explain why..
Over the weekend I installed a ported supercharger. I noticed no change in boost,A/F, or MAF counts. All remained unchanged.
I think all a port does is make it easier to flow the air, thus taking less power to turn the rotors at the same RPM. A pump is a pump. If its going to flow a certain amount of air at a givin RPM, its going to flow that no matter what. Unless you change the gearing(pulleys) it will flow the same at a givin engine RPM. Now, open it up a bit and the air passes through easier requiring less power to maintain that same rpm, and create less heat doing it. If you could spin that supercharger at say 8000 RPM on a bench and close up the outlet,or inlet a bit you would see the rpms drop a bit because you didnt increase the power to compensate for the blockage of airflow.
