Hello again guys. I'm hoping that more and more ported blowers are starting to get to people now. I also know that GTP's and Cobra's benefit greatly from these. The before and after pictures on INTENSE's website look great! Anyway, I'm sure these provide good gains, but I have some questions for people who have them. How much more boost did you gain? How much did IAT2 temps drop? I would assume it boosts much faster? Does ANYONE have any before and after dyno or track results? I'm getting ready to do the custom CAI, and water injection, and thought a ported blower would compliment thoset nicely. If I had the money, I'd just go whipple and call it a day. Anyway, sorry for the long post, just looking for feedback on the ported blowers. Take care.

 

Nobody has one?! Also, I forgot to mention, let me know what brand you went with. I think our only options right now are INTENSE, and Stiegemeier.

 

Me and my friends ported my blower ourselfs, and let me tell you it makes a huge diff, iam getting almost 19lbs of boost, you can certainly feel gains, dont have a dyno, but i can tell a diff, and the boost is there, it is also louder.

 

Sweet, thanks for the response. I always thought that a ported blower would really help. It would be nice to actually see test results. Currently, I see 19.2lbs of boost with a 2.5" pulley-no KR. After the CAI and ported blower, I'm thinking I'll be over 20lbs. Then I'll have the water injection to help cool things down, and allow me to run more timing. I can't wait! You didn't happen to take any pictures of your blower before and after, did you?

 

Intense Stage 5 makes a mention of ported blower. Is it absolutly necessary? I know it will benefit but I am not keen on waiting for mine to get ported and I am not going to accept someone else's blower (2nd hand used and possible issues).

I'd just take it somewhere here local to get ported.

If you guys are into the 19+ PSI range, where is the "safe" limit of the head gasket?

 

I'm willing to do this kit for now but only after I put my car away in storage for the winter and I can work on getting my blower ported and PCM programmed after I've sent it in.

 

I think your wrong man, when you free the engine you see a drop in boost. For example when I was stock without exhaust and intense pulley I would see almost 17 lbs and when I got intake and exhaust I saw it down to like 15 to 16. so youll probably be at like 18lbs when u get the intake.

 

Selfinfliction blew his at 24psi and again between 22 - 24. The second time he also noticed a cracked piston. This was using some other blower that is yet to be announced. This could have been because of the tune. If there was any preignition it would send the pressure level into the extremes. I think he was also doing this before HP Tuners was released.

I doubt we will see those levels from an M62.

Freeing up the pre-blower side should yeild an increase in boost, while freeing up post-blower would decrease resistance and pressure.

 

I've seen wicked things with an M62 that would make you ****. Also i've seen someone push 25 PSI with an M90 on a Buick Regal. Talk about insane screaming!

 

That is crazy considering that Eatons supposedly start to really lose their efficiency after ~13 PSI.

 

how does one exactly port a blower...?

 

They lose there HP ability but they still make torque! Actually the new gen eatons still gain HP after 18 PSI but the gains are so small after that.

 

A good performance shop or a place that does nothing but port exhaust manifolds, throttle bodies and superchargers do a good job at this stuff.

 

To port the blower, you would grind down the intlet of the supercharger housing, smooth out everything, me and some friends did mine with a dremel tool, and it worked out great, free mod for me, and it really made a diff, after we ported it we cleaned it all up, and grased it up, and no witht he mods in my sig, iam seeing a hair shy of 19lbs of boost.

 

That's just porting the inlet. I think they also port and polish the housing where the blades are.

 

Ok. I guess the helical blade design helps them stop the pressure from beeding back through the blades.

 

Why would you want to port the housing where the blades are, porting the inlet would be best, becuase thats where all the air is coming from. The porting that was done to my blower proved to work, showing higher boost, and a deff, increase over before.

 

It was acually the outlet, that was ported and smoothed all out on mine, you wouldnt need to do the housing.

 

Yeah if you ported the housing wouldn't you need to get new blades or something? Since the blades move the air from top to bottom via the blower housing, but if the housing was bigger the air would just slip past the blades.

 

You're right. I just looked a Stiegmier's site. The only time the housing is if there is a major rub from the rotors. They machine it out to add clearance and prevent excessive wear.

 

On a ported eaton, you don't want to actually port the inside of the housing, this can make the efficiency worse. I learned that from the M90's on GTP's. You want to port and open up the inlet and outlet only, and then polish it smooth. This will then flow more air, and atleast on the M90's, drop outlet temps a little. Ljavy, cobalt supercharged already corrected you. A CAI, or bigger throttle body, basically anything before the blower like he said, will INCREASE boost. Freeing up the heads, bigger cams, bigger exhaust,(etc.) will cause a DECREASE in boost because it's getting out quicker. Since I'm not changing my exhaust setup, and only freeing up incoming restrictions, I should see an increase in boost.

I'm going to guess that the cracked piston was from some KR(unless he was past the stock piston's limit). The other question I have is if he was seeing 24psi, how much timing was he seeing? I will probably be real close to 20psi and 24 degrees of timing after the next setup.

 

My brother got his lightning ported from steg and they did a wonderful job he is running in the mid 12s just from that and a intake but. I talked to him about doing my blower and he said he will port and polish it for 600$ so if you are thinking about getting it done i whould give him a call he does very good work

 

I'm not sure. I think he said that he was at almost no knock the first time. Which would mean that there was some. He also said that he didn't check to see if the crack was there after the first headgasket malfunction. I almost wonder if it wasn't caused by coolant getting on the hot piston.

I have no clue what his tune was. He wouldn't even say who he was testing for or what kind of blower it was.
